Monolithic crystalline silicon solar cells with SiNx layers doped with Tb~(3+) and Yb~(3+) rare-earth ions

In this study, we propose the fabrication of monolithic crystalline silicon solar cells with Tb~(3+) and Yb~(3+)- doped silicon nitride (SiN_x) layers by low-cost screen-printing methods. The performances of c-Si solar cells can be enhanced by rare-earth ions doped SiN_x layers via the mechanism of spectrum conversion. These SiN_x doped and codoped thin films were deposited by reactive magnetron co-sputtering and integrated as the antireflection coating layers in c-Si solar cells. The characterizations of SiN_x, SiN_x:Tb~(3+) and SiN_x:Tb~(3+)-Yb~(3+) thin films were conducted by means of photoluminescence, Rutherford backscattering spectroscopy, Ellipsometry spectroscopy and Fourier transform infrared measurements. Their composition and refractive index was optimized to obtain good anti-reflection coating layer for c-Si solar cells. Transmission electron microscopy performs the uniform coatings on the textured emitter of c-Si solar cells. After the metallization process, we demonstrate monolithic c-Si solar cells with spectrum conversion layers, which lead to a relative increase by 1.34 %in the conversion efficiency.

The resulting structure-property correlations of the WBG donor polymers were also discussed to highlight the importance of chemical modifications, which have promoted the great progress of NF-PSC field. Finally, an outlook for future innovations of WBG donor polymers and their NF-PSCs was provided.
Transition metal coordinated framework porphyrin for electrocatalytic oxygen reduction

Oxygen reduction reaction (ORR) constitutes the core process of many clean and sustainable energy systems including fuel cells and metal-air batteries. Developing high-performance and cost-efficiency ORR electrocatalysts is of great significance to the practical applications of the above-mentioned energy storage devices. Transition metal coordinated porphyrin electrocatalysts are highly considered as a promising substitution of noble-metal-based electrocatalyst because of their high ORR reactivity, where the ORR performances of the porphyrin-based electrocatalysts are highly dependent on the transition metal center. Herein a series of framework porphyrin electrocatalysts coordinated with different transition metal centers (M-POF, where M is Mn, Fe, Co, Ni, Cu, or Zn) was designed, synthesized, and evaluated in regards of electrocatalytic ORR performances. Among all, the Co-POF electrocatalyst exhibits the best ORR performances with the highest half-wave potential of 0.81V vs. RHE and the lowest Tafel slope of 53 mV/dec. This contribution affords an optimized high-performance ORR electrocatalyst and provides instructions for further rational design of porphyrin-based ORR electrocatalysts for sustainable energy applications.

光谱对斑翅果蝇和黑腹果蝇成虫趋光行为的影响

斑翅果蝇Drosophila suzukii和黑腹果蝇D.melanogaster是为害甜樱桃的优势种(郭建明,2007)。关于这2种果蝇的研究主要集中于地理分布、形态鉴定、分类检索、寄主与危害、生物学和生态学特性以及综合治理等方面(林清彩等,2016)。目前,常采用糖醋酒液诱集、色板诱集的方法进行害虫预测预报和物理防治,在田间多采用色板与食物相结合的方法来防治果蝇成虫。利用昆虫趋光性对成虫进行灯光诱杀已广泛用于防控多种害虫(伍苏然等,2007),但对于果蝇趋光性的成因未见深入研究。本试验应用光行为学方法研究不同波长光对斑翅果蝇和黑腹果蝇成虫趋光行为的影响,试图揭示光源特征与其趋光性间的内在联系,以期为研发高效测报和防治这2种果蝇的光源或光活性物质提供科学依据。
Modeling and characterizing the typical under-ice acoustic channel for the Arctic

The properties of arctic underwater acoustic channel were researched using Burke-Twersky (BT) model and ray theory. In the BT model, sea ice ridge is assumed as a set of semi-elliptical cylinder randomly distributed on a stress-free surface. By approximation of low frequency and high frequency of the BT model, the reflection coefficients were calculated at different frequencies. On the basis of ray theory, the acoustic field was calculated and the properties of underwater acoustic channel was analyzed. Compared to underwater acoustic channel properties when the boundary is air, the results show that under the ice surface some sound rays disappear during transmission, because the ice surface reflection coefficients is less than absolute soft surface. Especially, the higher the frequency, the higher the under-ice transmission loss. As a result, under-ice condition is unfavourable for acoustic signals to travel far. Besides, as to the channel structure, the reflection coefficient of ice layer is smaller, the channel multi-path structure is not significant compared to water-air interface without ice. The research results are valuable for our understanding of hydroacoustic channel and the prediction of the sonar system working in the polar region.
中期妊娠合并扩张型心肌病1例报告

讨论扩张型心肌病是一类以左室、右室或双心腔扩大和收缩功能障碍为特征的复合型心肌病,病毒感染、遗传及免疫因素在疾病的发生发展中起到了重要作用。其诊断主要依靠超声心动图,但需排除其他可能造成类似心脏结构及功能改变的疾病。扩张型心肌病起病隐匿,进展缓慢,一旦出现心脏衰竭现象,患者的心功能发生进行性恶化,心脏功能控制难度加大,合并症也越来越多,因此,扩张型心肌病的早期诊断和早期干预极为重要。目前主要措施包括强心、利尿、抗凝、扩张血管及起搏治疗等,以达到改善症状,延缓病情进展,提高患者生存率的目的,心脏移植仍然是在最后阶段治疗扩张型心肌病最有效的方法。国外文献报道妊娠合并扩张型心肌病的发病率约为29/10万,国内缺少相关报道。妊娠合并扩张型心肌病患者的母儿结局与患者的心功能密切相关,定期产检并进行NTBNP检查、超声心动图等检查,及时发现病情并评估妊娠风险,予以强心、利尿等治疗的同时适时终止妊娠,往往能取得较好结局。本例患者入院后经全面评估心功能为Ⅱ~Ⅲ级,左室射血分数不足20%,NTBNP等心肌损伤标志物远远超过正常值,继续妊娠风险极大,故积极予以终止妊娠。在终止妊娠的方式上可根据患者的孕周、心脏耐受能力等来选择。考虑本例患者心功能极差,行双持硬膜外阻滞下剖宫取胎术,终止妊娠效果较为满意。总之,对于妊娠合并扩张型心肌病患者,予以强心、利尿、营养心肌等治疗的同时应联合多学科、多方法全面评估患者心功能及妊娠风险,做到早期诊断,密切监测,适时终止,以改善妊娠结局。
Bismuth-interlayer-based Stable Electrode for Efficient and Stable Halide Perovskite Solar Cell

Highly efficient and low-cost halide perovskite solar cells (PSCs) have attracted great attention over the last few years as one of the most promising photovoltaic (PV) technologies.Yet,to gauge the technical feasibility for commercialization of PV technologies,the long-term stability of PSCs is still a challenge that must be addressed.
Optical coherence tomography for ocular surface and corneal diseases:a review

The advent of optical coherence tomography (OCT) imaging has changed the way ophthalmologists image the ocular surface and anterior segment of the eye.Its ability to obtain dynamic,high and ultra-high resolution,cross-sectional images of the ocular surface and anterior segment in a noninvasive and rapid manner allows for ease of use.In this review,we focus on the use of anterior segment OCT,which provides an "optical biopsy" or in vivo imaging of various ocular surface and corneal pathologies,allowing the clinician to diagnose diseases otherwise not visualized by traditional methods.The utility of anterior segment OCT for various anterior segment pathologies is reviewed.
Open and robotic radical prostatectomy

Open retropubic radical prostatectomy has been the “gold standard” treatment for locally confined prostate cancer (PCa) but in recent years minimal invasive techniques as laparoscopy and robot-assisted prostatectomy have become widely available. The trifecta of the surgical treatment of PCa is cancer control, the preservation of continence, and erectile potency. Over the years the complication rates of radical prostatectomy have become very limited with improved cancer control and better functional results.We review the indications and the surgical technique of radical prostatectomy, be it open or laparoscopic, eventually robot-assisted as well as the pre- and postoperative measures and the surgery-related consequences.
Ichthyoplankton recruitment from mainstream of the Changjiang River into the Dongting Lake,the second largest freshwater lake in China

Floodplains are important and distinctive ecosystems around the world,and the recruitment of ichthyoplankton from river to floodplain lakes is crucial to maintain this unique ecosystem.However,this process has not been well documented.In this study,ichthyoplankton were sampled to investigate the details of ichthyoplankton recruitment from the Changjiang (Yangtze) River to the Dongting Lake via a floodway channel,the Songzi River,from May to July in 2013 and 2014.During the study period,41 species of eggs and larvae were sampled.Among the samples,16 were river-lake migratory species (RL),representing 23.5% of the species in the Dongting Lake.In 2013,an estimated 130 million eggs and 3 180 million larvae drifted through the sampling section,and in 2014,an estimated 1 060 million eggs and 1 040 million larvae drifted through the sampling section.The amount of eggs and larvae of RL reached 3 210 million in 2013 and 1 850 million in 2014,respectively.These results demonstrated the importance of ichthyoplankton recruitment from the river to the lake,as species diversity will decrease sharply without this recruitment.Canonical correspondence analysis (CCA) showed that water temperature and water flow are the two most important factors influencing the spawning activities of fish.To maintain the high fish diversity in the Changjiang floodplain,we suggest to irrigate the channel to increase water discharge and increase the transport of ichthyoplankton from the Changjiang mainstream into the Dongting Lake.
Production of bio-fertilizer from Ascophyllum nodosum and Sargassum muticum (Phaeophyceae)

Oceans and seas form a large body of water that contains a natural biodiversity.For humans,represents a resource,which makes this a point of interest,from researches to improve the economy.Seaweeds produce many compounds and secondary metabolites that can be used in diff erent fields of industry such as food,agricultural,pharmaceutical and health.Even though seaweeds are ancestral resources,recently it was notorious a global interest in knowing more about its potentials,where biotechnology plays an important role in research.Studies showed that seaweed has many bioactive compounds beneficial to plant development,giving them a great potential as an agricultural fertilizer.Adding seaweeds to the soil provides organic matter,minerals,trace elements,growth plant regulator,metabolites,vitamins,and amino acids and it can work as a soil conditioner.In Portugal,the use of seaweeds for agriculture is important since long time ago.In the past,populations that lived near coastal zone depended on the seaweeds as a family subsistence but,throughout the years,synthetic fertilizers replaced seaweeds.Our work aimed to assess the potential of the extracts obtained from Ascophyllum nodosum and from Sargassum muticum as an agricultural fertilizer.This evaluation was carried out with rice plants (Oryza sativa) and lettuce (Lactuca sativa),in germination bioassays,the culture of rice and lettuce plants in pots,and culture of lettuce plants in hydroponics.For that,seaweed liquid extracts were used in diff erent concentrations in diff erent bioassays.Results show that extracts obtained from two seaweeds,A.nodosum and S.muticum,can be promissory plant biofertilizer at a concentration of 25% and had a positive eff ect on seed germination,plant development,and production.
Extracts of the seaweed Bifurcaria bifurcata display antifungal activity against human dermatophyte fungi

Bifurcaria bifurcata is a seaweed of the Order Fucales (Ochrophyta,Phaeophyceae) that can be found all year round along the Portuguese Atlantic shore.Although it is considered edible in some countries,its biotechnological potential has not yet been assessed in detail and here we report its antimicrobial potential against human dermatophyte fungi.Three samples were harvested from Baleal Island (Peniche,Portugal) harvested in winter (BbPe);from Aguda Beach (Arcozelo,Vila Nova de Gaia,Portugal),harvested in autumn (BbAg) and a sample obtained by culturing the Aguda sample under laboratory conditions (BbLC).A broth macrodilution assay was applied to determine the MIC (minimum inhibitory concentration) and MLC (minimum lethal concentration) of the B.bifurcata extracts.Results show that the BbPe MeOH extracts were the most eff ective and had higher antifungal activity against all the tested dermatophyte strains than the BbLC and BaAg extracts [ Epidermophyton floccosum FF9 (100–200 μg/mL MIC;200 μg/mL MLC),Microsporum canis FF1 (400 μg/mL MIC;≥400 μg/mL MLC),Trichophyton mentagrophytes FF7 (100 μg/mL MIC;>800 μg/mL MLC),M.gypseum CECT 2908 (800 μg/mL MIC;≥800 μg/mL MLC),T.mentagrophytes var.interdigitale CECT 2958 (800 μg/mL MIC;≥800 μg/mL MLC),T.rubrum CECT 2794 (200 μg/mL MIC;≥400 μg/mL MLC)].In fact,only E.floccosum FF9 was sensitive to BbAg and BbLC MeOH extracts.To our knowledge,this is the first report of antifungal activity of B.bifurcata against human dermatophyte fungi.
A mini-review on the microbial continuum:consideration of a link between judicious consumption of a varied diet of macroalgae and human health and nutrition

As the primordial,prokaryotic inhabitants on Earth,microbial entities were responsible for significant influences on the pathways taken in the development of life as we know it.The manifestation of numerous pathologies in humans is considered to be intrinsically associated with microbial dysbiosis in the gut (i.e.a poorly balanced microbiota).Such adverse health conditions include obesity,chronic fatigue syndrome,cancer,cardiovascular issues,neurological disorders,colitis,irritable bowel syndrome (IBS),and rheumatoid arthritis.Endosymbiotic events at the single cell level took place billions of years ago,eventually leading to eukaryotes,photosynthesis,and multicellularity.Macroalgae (seaweeds) were amongst the first organisms to develop these characteristics.Microbes and macroalgae interacted in a pattern of co-evolution,a process that applies to most,if not all living organisms.It is recognized that the normal human microbiome consists of over a trillion microorganisms,including about 2 000 commensal bacterial species typically stationed in the gut.Many of these live in the colon,where they function in the digestion of foods,releasing bio-available nutrients,bioactive molecules,and various metabolites.They mediate communication signals between the gut and the brain,and promote the normal development of immune function,metabolic activities,behaviour,and neurological stability.As very early humans foraged for food,some would have benefitted from coastal diets,rich in seaweeds and associated microbes.Such diets would have consistently provided all the nutrients essential for survival and growth,and as such,could have conveyed competitive advantages and contributed to enhanced cognitive sophistication.This mini-review article highlights studies regarding the health benefits of dietary fibres and the production of short chain fatty acids (SCFA).Insights are off ered regarding the positive eff ects the inclusion of macroalgae into the standard,Western diet can deliver in terms of providing appropriate fodder for those microbial populations deemed beneficial to human health and wellness.
Ambient noise Love wave tomography of China

We first report on the Love wave tomography of China based on ambient noise cross-correlations. We used 3 years of continuous waveform data recorded by 206 broadband seismic stations on the Chinese Mainland and 36 neighboring global stations and obtained Love wave empirical Green’s functions from cross-correlations of the horizontal components. The Love wave group velocity dispersion measurements were used to construct dispersion maps of 8- to 40-s periods, which were then inverted to obtain a threedimensional horizontally polarized S-wave (SH) velocity structure. The resolution was approximately 4° ×4° and 8° ×8° for eastern and western China, respectively, and extended to a depth of approximately 50 km. The SH model was generally consistent with a previously published vertically polarized S-wave (SV) model and showed large-scale features that were consistent with geological units, such as the major basins and changes in the crustal thickness across the north-south gravity lineament. The SH and SV models also showed substantial differences, which were used to examine the subsurface radial anisotropy. We define the radial anisotropy parameter as ψ= 2(V_(SH)-V_(SV)) = (V_(SH)+V_(SV)). At a shallow depth, we observed significant radial anisotropy under major basins, which may be related to thick sedimentary layers. At the mid to lower crust, most of the Chinese continent showed strong positive radial anisotropy (SH > SV). Central and southern Tibet showed strong positive anisotropy, whereas the radial anisotropy was relatively weak at the northern and eastern margins, which suggests a change in deformation style from the plateau interior to its margins. The North China craton showed prominent positive radial anisotropy, which may be related to decratonization and strong extension since the Mesozoic Era. Love waves are less well retrieved than Rayleigh waves from ambient noise cross-correlations. Increasing the duration of the cross-correlation data beyond 4 to 8 years may not aid in retrieving Love waves of longer periods, for which improved methods need to be explored.
High damage threshold liquid crystal binary mask for laser beam shaping

In order to improve the damage threshold and enlarge the aperture of a laser beam shaper, photolithographic patterning technology is adopted to design a new type of liquid crystal binary mask. The inherent conductive metal layer of commercial liquid crystal electro-optical spatial light modulators is replaced by azobenzene-based photoalignment layers patterned by noncontact photolithography. Using the azobenzene-based photoalignment layer, a liquid crystal binary mask for beam shaping is fabricated. In addition, the shaping ability, damage threshold, write/erase flexibility and stability of the liquid crystal binary mask are tested. Using a 1 Hz near-IR (1064 nm) laser, the multiple-shot nanosecond damage threshold of the liquid crystal mask is measured to be higher than 15 J=cm2. The damage threshold of the azobenzenebased photoalignment layer is higher than 50 J=cm2 under the same testing conditions.
Modelling and development of recycled water conditioning of copper-molybdenum ores processing

Current use of enrichment and processing technologies of ores requires the introduction of closed circuits of water treatment. A decrease in technological properties is caused by accumulations of ion-molecular components in the circulating water. The objective of the simulation is to determine the maximum allowable concentrations of ions and molecules as well as the choice of conditions for deposition or adsorption. First of all, our examinations decrease the concentration of copper ions and fatty acids in the circulating water. By pre-mixing water with the highest concentration of these ions, a reduction of copper ion and fatty acid concentrations in the recycled water occurs. The results do not only ensure the achievement of the maximum permitted concentration (MPC) of copper and iron, significantly reducing the amount of oxidized copper, they also make it possible to use the united sewage as current water for the flotation process. Mixing and adding filtrate of tailings, discharges of urban wastewater treatment and effluent of ash pit of thermal power stations (TPS) to recycled water causes an increase in the capacity of the enrichment plant by 15–17%.
Degradation behavior of concrete under corrosive coal mine environment

Experimental investigations were taken for the degradation of concrete under coupling effects of hydrochloric acid mist and mixed salt mist consisting of chlorine and sulfate and carbon dioxide according to coal mine environment. Concrete specimens were subjected to four different deterioration time from 45 days to 180 days, with an interval of 45 days. The results showed that the carbonization depth of concrete increased speedy at first, then gently and then rapidly again with the change of fragility. The compressive strength of concrete increased at the initial stage of deterioration, and then decreased until the time of 135 days when they came to the second ascension of small quantity and then entered the decline trend under the coupling effect of carbonization and acid-salt attack. The elastic modulus changed slightly with the deterioration, meanwhile the fragility and ductility changed significantly before and after deterioration time of 180 days, which was identical to the failure modes.
Subsidence over room and pillar retreat mining in a low coal seam

The objective of this paper is to study the behavior of a low thick and low depth coal seam and the overburden rock mass. The mining method is room and pillar in retreat and partial pillar recovery. The excavation method is conventional drill and blast because of the small production. The partial pillar recovery is about 30% of the previous pillar size, 7 m × 7 m. The roof displacement was monitored during retreat operation; the surface movement was also monitored. The effect of the blasting vibration on the final pillar strength had been considered. Due to blasting, the pillar reduced about 20%. The consequence is more pillar deformation and roof vertical displacement. The pillar retreat and ground movement were simulated in a three-dimensional numerical model. This model was created to predict the surface subsidence and compare to the subsidence measured. This study showed that the remaining pillar and low seam reduce the subsidence that was predicted with conventional methods.
Underground ground control monitoring and interpretation, and numerical modeling, and shield capacity design

Mine or longwall panel layout is a 3D structure with highly non-uniform stress distribution. Recognition of such fact will facilitate underground problem identification/investigation and solving by numerical modeling through proper model construction. Due to its versatility, numerical modeling is the most popular method for ground control design and problem solving. However numerical modeling results require highly experienced professionals to interpret its validity/applicability to actual mining operations due to complicated mining and geological conditions. Underground ground control monitoring is routinely performed to predict roof behavior such as weighting and weighting interval without matching observation of face mining condition while the mining pressures are being monitored, resulting in unrealistic interpretation of the obtained data on mining pressure. The importance of ground control pressure monitoring and simultaneous observation of mining and geological conditions is illustrated by an example of shield leg pressure monitoring and interpretation in an U.S. longwall coal mine: it was found that the roof strata act like a plate, not an individual block of the size of a shield dimension, as commonly assumed by all researchers and shield capacity is not a fixed property for a longwall panel or a mine or a coal seam. A new mechanism on the interaction between shield's hydraulic leg pressure and roof strata for shield loading is proposed.
