SILVER ECONOMY IN RURAL AREAS IN THE CONTEXT OF (UN)SUSTAINABLE DEVELOPMENT
Authors: Krzyminiewska Grażyna
Published: September 2019

he aim of the article is to show how the implementation of the silver economy can enable the transformation of demographic problems into opportunities for the development of rural areas. Desk research and descriptive analysis are applied and the study is based on documents of international organisations, a critical literature review and secondary sources. The problem of the ageing Polish society (inhabitants of rural areas) and its resulting social and economic consequences have formed the basis of a new paradigm of development – the development of the silver economy The effect of the analysis is the thesis that the development of the silver economy may be of unsustainable character, where rural areas become beneficiaries to a lesser extent, thus generating new social inequalities and the development of destructive phenomena. The issue of the ageing rural population in Poland, the concept of the silver economy as a new paradigm of development in rural areas and the problems associated with it are presented in the study. The consistent development of the silver economy offers the opportunity of weakening the effects of the ageing population. Recognizing the potential of seniors will allow for greater development benefits which can be gained by the country’s economy or the economy of individual regions. The importance of the ethical aspect of the ageing rural population, which is the prevention of unsustainable development of the silver economy from a regional and environmental perspective, is highlighted.
The impact of tax optimization on the picture of the financial position of enterprises
Authors: Adamczyk Adam
Published: September 2019

The paper discusses the impact of tax optimization in the area of corporate income tax on the picture of
the company's financial position. The purpose of the article is to answer the question whether the introduction
of a preferential, reduced rate of corporate income tax for small taxpayers affected the dynamics
of revenues from sales and financial results presented by enterprises. The study used the histogram analysis
method and U Mann-Whitney's non-parametric test for independent trials. The article confirmed the
thesis that the application of a preferential tax rate with a simultaneous rigid revenue criterion resulted in
a reduction in the dynamics of sales revenues in the research sample entities. At the same time, it was
proved that despite the decrease in sales revenue, the net profit of entities using the preferential rate was
improved. The original contribution of the work is the application of the original research methodology.
A balanced paradigm of higher education in the context of integrated reporting
– academic teachers’ perspective
Authors: Chłapek Katarzyna , Krajewska Sylwia , Jonas Krzysztof
Published: September 2019

Integrated reporting is a complex process of creating and presenting information about an enterprise's
activities that significantly exceeds the traditional financial reporting framework. Difficulties in the preparation
of non-financial information and ensuring its high quality imply changes in the teaching model.
The aim of this study is to examine the opinion of academic teachers on the content and teaching methods
used in the context of their adaptation to integrated reporting requirements. According to the authors, only
the combination of hard and soft skills in accounting teaching will allow further development of integrated
reporting. The basic research methods used to verify this hypothesis are surveys and literature studies,
as well as formulating conclusions on the basis of the deduction and synthesis methods. The conducted
research indicates the need for modification of accounting education to adapt it to market requirements.
Disclosure of risk areas and factors in the reports on the activities of listed companies
– observations regarding changes in legal regulations
Authors: Karmańska Anna , Łada Monika
Published: September 2019

The aim of the paper is to present the results of empirical research on the changes in the scope of risk
disclosures, expected in the year 2017 as a result of significant changes in accounting regulations. The
results of the research (qualitative and quantitative) are based on the analysis of reports on the activities
(management commentaries) of the largest WIG30 listed companies. In the analysis of the collected
empirical material, the event studies approach was used, i.e. the changes in the quantitative and qualitative
scope of disclosures before (in 2016) and after the introduction of new regulations (in 2017) were
compared. The research results indicate a selective increase in the scope of disclosures on risk areas and
factors as well as a significant increase in the risk rhetoric. The conclusions from the research confirm the
multidimensionality and complexity of phenomena related to narrative disclosures and the impact of legal
regulations of accounting on the scope of risk disclosures in the listed companies’ reports.
The size of the enterprise as a determinant of management accounting practice
Authors: Szychta Anna
Published: September 2019

The aim of the paper is to indicate differences in the application of management accounting methods and
the type of tasks that management accountants perform. It will also identify the type and importance of
factors determining the application of these methods in small, medium and large enterprises in Poland
that participated in the empirical study. The paper answers several research questions based on data
obtained from companies in a survey conducted in 2016. The study shows, among others, that in the third
decade of the development of the market economy, after the transformation of the political system in
Poland, enterprises, regardless of size, still mainly use traditional cost accounting systems; along with the
increase in the size of enterprises, the number of entities implementing the operational management
accounting methods increases. Strategic management accounting methods in large and medium-sized
entities are relatively rarely implemented, excluding long-term planning in large companies, which is
used in around 83% of the surveyed companies. Management accounting practice in Poland is now more influenced by economic factors than by institutional ones. Of the ten tasks of management accountants indicated in the study, the reduction of costs and expenses and the measurement of company performance were considered the most important.
Is accounting ready for the dual measurement in the statement of financial position and the statement of profit or loss? Content analysis of comment letters to the Exposure Draft of the Conceptual Framework
Authors: Mućko Przemysław , Janowicz Magdalena , Hońko Stanisław , Hendryk Michał
Published: September 2019

The aim of the paper is to study the responses of the IASB constituents to the Exposure Draft of the Conceptual Framework, given on the proposed matter of dual measurement for the statement of financial position and the statement of profit or loss, and to assess their potential impact on standard-setting and accounting practice. The authors briefly analysed the literature about measurement bases and then presented the results of their empirical research. The research methodology involves mainly content analysis of comment letters sent to the IASB in response to the Exposure Draft of the Conceptual Framework. On the basis of the gathered data, the authors concluded that despite the positive feedback that the proposal received, the number of suggestions made and the concerns it provoked may lead to the conclusion that the concept was introduced too early and thus not developed well. The IASB did not provide enough justification behind their proposal. The Board seems more interested in enforcing certain solutions than actually dealing with the problems related to them. The lack of a clear conceptual concept behind the dual measurement basis may cause it to remain rather an ad hoc tool used to forge a compromise. It may even be seen just as a post factum description of inconsistently applied measurement bases in IFRS.
SOCIAL AND ECONOMIC DEVELOPMENT STATUS OF EUROPEAN UNION COUNTRIES
Authors: Łuczak Aleksandra , Wysocki Feliks
Published: September 2019

The purpose of this paper is to compare the social and economic development statuses of European Union countries in 2005 and 2016. The study relied on bilinear ordering with the use of positional TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) approach. By applying these methods, it was possible to determine the development levels in social and economic fields, and in socio-economic development levels (six levels: from very low to very high). Furthermore, four main types of development status were identified: socially and economically beneficial; economically beneficial; socially beneficial; and socially and economically less beneficial. Central and Eastern European countries (including Poland in particular) witnessed a clear improvement in their development statuses in 2016 compared to 2005. In turn, countries experiencing clear deterioration primarily include Greece. In both years under consideration, Denmark and Luxembourg were the only countries to maintain a very high level of socio-economic development accompanied by a socially and economically beneficial development status. Eurostat data provided the empirical basis for this study.
AGRICULTURAL LAND PRIVATIZATION IN POLAND
Authors: Maśniak Jacek , Jędruchniewicz Andrzej
Published: September 2019

The aim of the article is to present the process of agricultural land privatization in Poland, taking into account the role that this policy has played in terms of shaping the Polish agricultural model, based on family households. The purpose of the agrarian system shaping policy is the protection and development of family households. To this end, the said group of agricultural households is being granted privileges in terms of access to agricultural land. From an economic point of view, it translates into replacing market allocation with political decisions. The sale of agricultural land on behalf of the state was conducted by the Agricultural Property Agency (APA), which on 1 September 2017 was merged with the Agricultural Market Agency and transformed into the National Center for Agricultural Support. Between 1992 and 2017, a total of over 2.6 million ha of agricultural land (amounting to 55% of all acquired land) was sold. Natural persons acquired a total of 81% of privatized agricultural land, 19% of which was acquired by legal entities. In the years 2005-2017, the prices of agricultural land demonstrated an upward trend. The prices obtained by the Agency were very close to private market prices. The average price amounted to EUR 4,504 per 1 ha in the case of state-owned land and EUR 4,716 per 1 ha in the case of private land.

Authors: Dominiak Natalia , Oleszczyk Natalia
Published: September 2019

The aim of the analysis was to determine the trends of changes in the level of economic development in four voivodships: West Pomeranian, Pomeranian, Warmian-Masurian and Podlaskie. The study discusses the genesis of economic development, using the example of countries with oil deposits. The thesis presents the approach of development by Adam Smith, John S. Mill, Paul Krugmann and others. The research was carried out based on secondary data obtained from the Local Data Bank of the Central Statistical Office. The publication applies, among others, an analysis of sources of domestic and foreign literature as well as an index analysis, the results of which were presented in tabular form. For the purpose of this publication, the author used an analysis of sources of domestic and foreign literature as well as an analysis of secondary data expressed in real terms, the results of which have been presented in tabular form. The publication uses current quality data. The assessment of changes in the context of development covered the years 2004-2017. The analyses made indicate an increase in the level of economic development in individual voivodships in the examined period. The research has shown a growing trend in the value of analysed economic values (including GDP per capita). The Pomeranian Voivodship achieved the greatest growth. A divergence in the level of economic growth of voivodships located in eastern and western parts of Poland is visible. The voivodships located at the eastern Polish border, i.e. Warmian-Masurian and Podlaskie, show a significant slowdown, achieving the lowest development parameters.

Published: September 2019

The aim of the study is to compare price competitiveness in Poland and Lithuania based on selected food products and catering services. Special attention was paid to selected parameters characterizing both countries and retail prices of products available under specific brands in selected retail outlets. Secondary and primary studies were carried out for the purpose of the research. Empirical research in the field of price competitiveness of selected food products and catering services was carried out in Poland and Lithuania in May and June of the current year. As a hypermarket, Carrefour was selected in Poland, while in Lithuania - Maxima, and as a supermarket, Carrefour Express (Poland) and IKI (Lithuania). The selection of these stores was made on the basis of retail trade reports in Poland and Lithuania presenting the largest retail chains. Based on our research, it can be pointed out that the products available on the Polish market were mostly characterized by lower prices compared to products present on the Lithuanian market. This indicates their greater price competitiveness.
OPINION OF THE LOCAL COMMUNITY ON THE TOURIST ATTRACTIVENESS OF THE COMMUNE AND SELECTED AGRITOURISM DEVELOPMENT FACTORS
Authors: Roman Michał
Published: September 2019

The main objective of the research was to present the opinion of the local community on the tourist attractiveness of the commune of Siemiatycze (Podlasie province) and selected factors of agritourism development. In order to fully and objectively recognise such factors, empirical material was collected with the use of the diagnostic survey method and survey questionnaire. Research was conducted in May 2019 and the questionnaire was sent to commune inhabitants. 52 respondents took part in the research. In addition, the author used the method of CATI (computer-assisted telephone interviewing) with 11 owners of overnight accommodation facilities operating in Siemiatycze commune. Research shows that the tourist attractiveness of the commune has a significant impact on the level of agritourism development. In addition, the majority of surveyed residents (73.1%) considered the area of the Siemiatycze commune as conducive to the development of tourism and agritourism. In their opinion, the area of the commune is rich in natural and cultural values and is characterized by high forest cover, the occurrence of meadows, ponds and rivers. The majority of respondents (80.1%) believed that the development of agritourism could increase the income of the population and raise the standard of living. Only 15.4% of respondents believed that agritourism could bring negative effects, e.g. taking over negative patterns of behaviour (especially young people), destroying traditional equipment and buildings, and the aversion of the community towards visitors.
THE EFFECTS OF SOME AGRI FOOD TRADE RELATIONSHIPS CONCERNING BREXIT IN EASTERN EUROPEAN COUNTRIES
Authors: Vásáry Miklós
Published: September 2019

The aim of the study is to examine which part of agricultural and food trade between Visegrad countries and the United Kingdom is threatened by Brexit. On 23 June 2016, the United Kingdom voted in a referendum to leave the European Union, but this has not yet taken place, though it should have happened by 29 March 2019. Therefore, it remains uncertain and the conditions the exit remain to be seen. In the absence of a final agreement, it is only possible to determine currently competitive sectors that could remain in this situation in the future, too. Competitiveness studies can provide guidance to determine expected effects. For products with a lower competitiveness value, turnover is expected to decrease due to changing regulations or increasing duties. Based on the long-term analysis of agri-food trade values of the parties, it is clear that markets are sufficiently diversified. So British withdrawal will not result in significant consequences in the case of Visegrad countries. In terms of trade relations, highly processed products are expected to be competitive in the future.
THE VALUE OF OCCUPATIONAL SAFETY – ESTIMATION OF LOST PRODUCTIVITY IN THE POLISH AGRICULTURAL INDUSTRY
Authors: Jakubowska Agnieszka , Rosa Anna
Published: September 2019

The study was to assess the level of lost productivity of human resources in the Polish agricultural industry determined by working conditions. The assumed analysis was conducted in a time frame by assessing the accident ratio and its economic consequences in Polish agriculture. The estimation of costs of lost productivity is based on the adoption of the so-called human capital approach. A comparison of the lost product value in the A section – “Agriculture, Forestry, Fishing”, with average results recorded in the economy indicates high divergence resulting both from existing differences in the scale of burden with consequences of incapacity for work and from the conducted valuation of working time against mean values in economy. Depending on the adopted criterion for valuation of the unit of working day, estimated values of lost productivity in the A section per one injured fluctuate between 22 and 150% of mean values obtained for economy in total, and between 30 and 212% per 1,000 persons working in the given section (year 2016). The obtained results, apart from indicating an economic aspect of relations between occupational safety and productivity, constitute the basis for discussion on the profitability of health “interventions”.
FEMALE ENTREPRENEURSHIP IN RURAL AREAS (EXAMPLE OF THE WIELKOPOLSKIE VOIVODSHIP)
Authors: Wojcieszak Monika
Published: September 2019

The purpose of the study presented in this paper is to indicate the conditions for, determinants of and barriers to female entrepreneurship. To meet the objective defined above, the author relied on the findings from her own survey conducted in 2019 with a sample of 213 women engaged in economic activity in rural areas of the Wielkopolskie Voivodship. In the group surveyed, most people offered trade-related services. Hairdressing and beauty services are another highly popular activity among the women covered by this study. Once collected from the respondents, the information was analyzed and described with the use of descriptive statistics methods. According to the respondents, the group of key conditions that promote entrepreneurship includes the availability of capital (funds for new and developing companies) and thoughtfully prepared educational and developmental programmes encouraging people to start their own business, as well as public policy for taxes etc. Other important conditions include adequate access to entrepreneurial instruments and measures, and adequate access to technical infrastructure. The interviewees believe that the greatest barrier faced when running a business is the complicated administrative procedure and a lack of startup funds.

Authors: Penfold Naomi C , Polka Jessica K
Published: September 2019

Preprints are gaining visibility in many fields. Thanks to the explosion of bioRxiv, an online server for preprints in biology, versions of manuscripts prior to the completion of journal-organized peer review are poised to become a standard component of the publishing experience in the life sciences. Here we provide an overview of current challenges facing preprints, both technical and social, and a vision for their future development, from unbundling the functions of publication to exploring different communication formats.
Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights
Authors: Liberti Joanito , Görner Julia , Welch Mat , Dosselli Ryan , Schiøtt Morten , Ogawa Yuri , Castleden Ian , Hemmi Jan M , Baer-Imhoof Barbara , Boomsma Jacobus J , Baer Boris
Published: September 2019

Queens of social insects make all mate-choice decisions on a single day, except in honeybees whose queens can conduct mating flights for several days even when already inseminated by a number of drones. Honeybees therefore appear to have a unique, evolutionarily derived form of sexual conflict: a queen’s decision to pursue risky additional mating flights is driven by later-life fitness gains from genetically more diverse worker-offspring but reduces paternity shares of the drones she already mated with. We used artificial insemination, RNA-sequencing and electroretinography to show that seminal fluid induces a decline in queen vision by perturbing the phototransduction pathway within 24–48 hr. Follow up field trials revealed that queens receiving seminal fluid flew two days earlier than sister queens inseminated with saline, and failed more often to return. These findings are consistent with seminal fluid components manipulating queen eyesight to reduce queen promiscuity across mating flights.
Consistent and correctable bias in metagenomic sequencing experiments
Authors: McLaren Michael R , Willis Amy D , Callahan Benjamin J
Published: September 2019

Marker-gene and metagenomic sequencing have profoundly expanded our ability to measure biological communities. But the measurements they provide differ from the truth, often dramatically, because these experiments are biased toward detecting some taxa over others. This experimental bias makes the taxon or gene abundances measured by different protocols quantitatively incomparable and can lead to spurious biological conclusions. We propose a mathematical model for how bias distorts community measurements based on the properties of real experiments. We validate this model with 16S rRNA gene and shotgun metagenomics data from defined bacterial communities. Our model better fits the experimental data despite being simpler than previous models. We illustrate how our model can be used to evaluate protocols, to understand the effect of bias on downstream statistical analyses, and to measure and correct bias given suitable calibration controls. These results illuminate new avenues toward truly quantitative and reproducible metagenomics measurements.
Actomyosin regulation by Eph receptor signaling couples boundary cell formation to border sharpness
Authors: Cayuso Jordi , Xu Qiling , Addison Megan , Wilkinson David G
Published: September 2019

The segregation of cells with distinct regional identity underlies formation of a sharp border, which in some tissues serves to organise a boundary signaling centre. It is unclear whether or how border sharpness is coordinated with induction of boundary-specific gene expression. We show that forward signaling of EphA4 is required for border sharpening and induction of boundary cells in the zebrafish hindbrain, which we find both require kinase-dependent signaling, with a lesser input of PDZ domain-dependent signaling. We find that boundary-specific gene expression is regulated by myosin II phosphorylation, which increases actomyosin contraction downstream of EphA4 signaling. Myosin phosphorylation leads to nuclear translocation of Taz, which together with Tead1a is required for boundary marker expression. Since actomyosin contraction maintains sharp borders, there is direct coupling of border sharpness to boundary cell induction that ensures correct organisation of signaling centres.
Plant density and life history traits of Aconitum spicatum in North-central Nepal: effects of elevation and anthropogenic disturbances
Authors: Chapagain Deep J. , Meilby Henrik , Ghimire Suresh K.
Published: September 2019

Increasing cross-border trade of medicinal and aromatic plants (MAPs) has put heavy pressure on a considerable number of species in the Himalayas. One of the threatened species in Nepal is Aconitum spicatum. Unfortunately for this species and for many others, our knowledge on population ecology and performance across the distribution range is insufficient, hindering the formulation of species-specific management plans. We therefore studied density and population structure of A. spicatum and assessed variation in its life history traits among three populations (subalpine, lower alpine and alpine) along an elevation gradient (3,000–4,200 m a.s.l.) in Annapurna Conservation Area, north-central Nepal. The results show that human disturbances and topographic factors contributed to the variation in density and life history traits. The overall density ranged between 0.56 ± 0.09 (Mean ± SE) and 2.48 ±  0.24 plants/m2 with highest mean density in the lower alpine and lowest in the subalpine population. The subalpine population was also characterized by lower investment in reproductive structures with lowest seed mass and low seed viability and fecundity. Among the environmental variables tested, harvesting, animal droppings and fire appeared to be the most important factors affecting density of different life stages of A. spicatum. The prevailing harvesting pattern is destructive as it involves uprooting of the whole plant and this appears to be a main reason for low recruitment and reduced density of the subalpine population. The level of disturbance decreased with increasing elevation. In terms of reproductive effort, the alpine population performed best. Our results indicate that the viability of A. spicatum populations depends on controlling over-harvesting and pre-mature harvesting of tubers and protecting younger life stages from grazing, trampling and fire. We therefore recommend that when formulating management guidelines, measures aiming to mitigate such anthropogenic disturbances should be considered.

Vulnerability of Local Communities to Oil Installation in Isoko Local Government Area of Delta State, Nigeria
Authors: Tammy Cookey A. , Bodo Tombari , Ukusowa M. M. P. , Igbogho Jude
Published: September 2019

Background of Study: Petroleum exploration has generated over 90 percent revenues to the Nigerian government, and as such the nation pays all her liabilities from the sales of petroleum products. Nigerian’s mono economy mostly based petroleum exploration, has brought a lot of sufferings to the people in the region where the oils are being drilled from. The people of Isoko Local Government Area (LGA) has suffered from the environmental pollution and devastation of their lands as a result of oil exploration activities for many years now, especially from numerous oil installations of the operating oil companies. This study examines the vulnerability of the local communities to these oil installations.

Materials and Methods: The study employed the use of questionnaire to acquire data relating to the vulnerability of communities to oil installation in Isoko LGA in Delta State. 600 copies of questionnaires were administered to the residents of the chosen communities using a simple random sampling technique which gives room for equal chance of any of the resident to be chosen in the study area. Descriptive statistics was used to explain the frequencies of the variables in terms of their percentage. Results of the analysis were presented using tables, bar charts, hazard maps, among others.

Results: it was revealed that the vulnerability to oil installation is high in the Isoko LGA, thereby leading to a high rate of environmental degradation in these communities.

Conclusion: it is concluded that end the suffering of the people to oil installations, the operating oil companies should pay special attention to needs of their host communities and proactive to any possible hazard that might have results from oil installation. The government should enforce the environmental laws that protect the environment and ensure that the multinational oil companies adhere strictly to them.

There are many historic alleys in central Kyoto. The alleys in Kyoto's historical townscape have commonly been considered part of its special charm. However, in recent years, such characteristics of this townscape are disappearing. This paper aims to analyze and discuss the disappearance of alleys from 2006 to 2016. The total number of alleys in the subject area declined 7.78%. The following three typical patterns of disappearance of alleys were identified: (i) A pattern where the plot of land that includes the alley is sold by the owner, and as a result, the building along the alley are demolished. Immediately after the alley disappears, collective housing is built. (ii) A pattern where the individual owners of the land, including the alley, decide to demolish the existing building along the alley and replace them with a new detached house. (iii) A pattern where a parking lot is built after the owner of the building along the alley demolishes them.

An organic electronic ion pump (OEIP) delivers ions and drugs from a source, through a charge selective membrane, to a target upon an electric bias. Miniaturization of this technology is crucial and will provide several advantages, ranging from better spatiotemporal control of delivery to reduced invasiveness for implanted OEIPs. To miniaturize OEIPs, new configurations have been developed based on glass capillary fibers filled with an anion exchange membrane (AEM). Fiber capillary OEIPs can be easily implanted in proximity to targeted cells and tissues. Herein, the efficacy of such a fiber capillary OEIP for modulation of inflammation in human monocytes is demonstrated. The devices are located on inflammatory monocytes and local delivery of salicylic acid (SA) is initiated. Highly localized SA delivery results in a significant decrease in cytokine (tumor necrosis factor alpha and interleukin 6) levels after lipopolysaccharide stimulation. The findings—the first use of such capillary OEIPs in mammalian cells or systems—demonstrate the utility of the technology for optimizing transport and delivery of different therapeutic substances at low concentrations, with the benefit of local and controlled administration that limits the adverse effect of oral/systemic drug delivery.

High‐performance liquid chromatography integrated with tandem mass spectrometry (HPLC–MS/MS) has become a powerful technique for proteomics research. Its performance heavily depends on the separation efficiency of HPLC, which in turn depends on the chromatographic material. As the “heart” of the HPLC system, the chromatographic material is required to achieve excellent column efficiency and fast analysis. Monolithic materials, fabricated as continuous supports with interconnected skeletal structure and flow‐through pores, are regarded as an alternative to particle‐packed columns. Such materials are featured with easy preparation, fast mass transfer, high porosity, low back pressure, and miniaturization, and are next‐generation separation materials for high‐throughput proteins and peptides analysis. Herein, the recent progress regarding the fabrication of various monolithic materials is reviewed. Special emphasis is placed on studies of the fabrication of monolithic capillary columns and their applications in separation of biomolecules by capillary liquid chromatography (cLC). The applications of monolithic materials in the digestion, enrichment, and separation of phosphopeptides and glycopeptides from biological samples are also considered. Finally, advances in comprehensive 2D HPLC separations using monolithic columns are also shown.

Constructing plasmonic hotspots in metal nanostructures is essential for plasmon‐enhanced spectroscopies (PESs), but their application in quantitative analysis is a long‐standing challenge. Herein, highly uniform, reproducible, stable, and sensitive 3D hotspots platform substrates are assembled on hydrophobic silicon wafers using a drop of solution containing silica coated surface plasmon resonance (SPR) active nanoparticles (NPs). Plasmon‐enhanced second harmonic generation (PESHG) and surface‐enhanced Raman scattering (SERS) experimental signals increase sharply with the increase of droplet evaporation time, which is attributed to the rapid increase of 3D hotspots generated by gradual decrease of distance between adjacent NPs. Compared with 3D bare metal NP substrate, 3D metal shell‐isolated nanoparticles (SHINs) substrate demonstrates much more stable PESHG and SERS signals attributing to the protecting SiO2 shells. Besides that, uniform distribution of 3D “hotspots” on the hydrophobic substrate can facilitate the quantitative analysis of an analyte using SERS. Experimental and theoretical results demonstrate that the 3D hotspots platform has the potential to be developed as a plasmon‐enhanced substrate for linear and nonlinear spectroscopies with practical sensing applications.

At present, dual‐channel or even multi‐channel recording is a developing trend in the field of photodetection, which is widely applied in environment protection, security, and space science and technology. This paper proposes a novel MoS2/InAlAs/InGaAs n–i–n heterojunction phototransistor by integrating multi‐layered MoS2 with InGaAs‐based high electron mobility transistors (InGaAs‐HEMTs). Due to the internal photocurrent amplification in the InGaAs channels with a narrow energy bandgap of 0.79 eV, this device exhibits high photoresponsivity (R) of over 8 × 105 A W–1 under near‐infrared illumination of 1550 nm at 500 pW. Furthermore, with the combination of the photoconductance effect in the vertical MoS2/InAlAs/InGaAs n–i–n heterojunction and the photogating effect in the lateral phototransistor, this device possesses a unique characteristic under visible illumination that its photoresponsivity can be tuned by the top gate electrode from 6 × 105 A W–1 to ‐4 × 105 A W–1 by gate voltage. This may lead to a new application as an optically controlled electronic inverter, which needs further study in depth. This MoS2/InAlAs/InGaAs phototransistor builds up a new bridge between 2D materials and conventional ternary compounded semiconductor devices.
Enhanced Performance and Stability of Ternary Organic Solar Cells Utilizing Two Similar Structure Blend Fullerene‐Free Molecules as Electron Acceptor
Authors: Liu Zhiyong , Wang Ning
Published: September 2019

Fullerene‐free organic solar cells (OSCs) are fabricated using a blend of J61 polymer as donor and the blend of m‐3,9‐bis(2‐methylene‐(3‐(1,1‐dicyanomethylene)‐indanone))‐5,5,11,11‐tetrakis(4‐hexyl phenyl)‐dithieno[2,3‐d:2′,3′‐d′]‐s‐indaceno[1,2‐b:5,6‐b′] dithiophene (ITIC) and ITIC‐Th as electron acceptor. The blend of m‐ITIC and ITIC‐Th as electron acceptor due to the similar lowest unoccupied molecular orbital energy levels and good compatibility among J61, m‐ITIC, and ITIC‐Th, are beneficial for the small energy barrier at the m‐ITIC:ITIC‐Th interface. Simultaneously, the ternary photoactive layer can maintain the optimize film morphology and beneficial to ensure effective suppression of charge recombination at the three kind materials interface. The power conversion efficiency of ternary OSCs achieves to 12.57% when the blend of m‐ITIC:ITIC‐Th (the ratio of m‐ITIC:ITIC‐Th is 40:60) as electron acceptor, with enhanced open‐circuit voltage (VOC) of 0.91 V, short‐circuit current densities (JSC) of 19.94 mA cm−2, and fill factor of 69.6%. Moreover, the optimal ternary OSCs show enhanced thermal stability and photostability than the binary OSCs. This study indicates that the blend of m‐ITIC and ITIC‐Th as electron acceptor and J61 as donor is a promising strategy to fabricate high performance and stable OSCs.
Optimal experimental design for optimal process design: A trilevel optimization formulation
Authors: Walz Olga , Djelassi Hatim , Mitsos Alexander
Published: September 2019

Typical optimal experimental design (OED) methods aim at minimizing the covariance matrix of the estimated parameters regardless of the intended application of the model that is being estimated. This can unnecessarily increase the experimental costs. Herein, we propose a new OED method, which tailors the designed experiments to the model application. The method is demonstrated for model‐based process design and aims at mitigating a worst‐case realization of the process design. The proposed formulation results in a min–max–min problem and is based on bounded‐error OED. The method is illustrated via an ad hoc solution method using two examples, a simple illustrative example and the van de Vusse reaction, that show the differences between typical and the new tailored OED method: experimental designs can be considered good using the latter method, while the same design would be considered bad with the former methods.
