The Paradox of Patience
Authors: Tebben Nicholas ,   Southwestern Philosophical Society
Published: July 2021

Some normative theories—act utilitarianism and rational decision theory among them—both designate some range of outcomes as particularly important, and, with an eye towards securing those outcomes, provide agents with advice concerning what is to be done. In this paper I argue that there are situations in which these two aspects of such theories are in tension. I provide a handful of conditions that, when jointly satisfi ed, pick out situations in which these theories recommend that agents act in ways that do not contribute to the outcomes on which they place value.

América Latina: amenazas y calidad de la democracia en el siglo XXI
Authors: Navarro Carlos Andrés Jiménez
Published: July 2021

La primera década del siglo XXI en América Latina ha trascurrido en la mayoría de los países bajo el control de gobernantes elegidos democraticamente, lo que no indica necesariamente que la democracia esté plenamente consolidada, sino que aún se encuentra en proceso de construcción. Por lo tanto, en medio del desarrollo de los procesos democráticos en la región, es necesario establecer factores que se conviertan en punto de partida para evaluar la calidad de las democracias; un primer factor que permite determinar de manera general la calidad de las democracias es la justicia, entendida como: La democracia opera con justicia, contenido de justicia dentro de las democracias y la democracia como herramienta para identificar injusticias. Asimismo, se determinaron tres aspectos identificados como amenazas latentes y permanentes para las democracias en la región: 1. Desigualdad e inequidad. 2. Participación e inclusión de la ciudadanía. 3. Personalización de la democracia.
Fim do consenso: a Política Externa Brasileira no século XXI
Authors: Bravo Juliano Dos Santos
Published: July 2021

Da política externa brasileira do governo Fernando Henrique Cardoso (1995-2002) à gestão atual, marcada pela consolidação do impeachment da presidenta Dilma Rousseff em agosto de 2016, pode ser vislumbrada como um arco de ascensão, consolidação e declínio. Entendemos que a ascensão e a consolidação foram possíveis devido a um consenso político interno em volta do presidencialismo de coalizão que produziu estabilidade, além, evidentemente, de inúmeros fatores internos e externos que são apreciados aqui de forma adjacente. A partir da eleição de Dilma Rousseff para o segundo mandato esse consenso foi desfeito. A ‘guerra’ política ficou amplamente aberta. Portanto, o objetivo central do artigo é visualizar esse arco da ascensão ao declínio para, dessa maneira, obter ferramentas analíticas capazes de identificar as primeiras marcas e desafios do governo atual, especialmente no que tange as capacidades de autonomia e desenvolvimento nacionais. Para tanto, o texto procura se auxiliar dos conceitos de autonomia e desenvolvimento produzidos e entendidos por grandes pesquisadores da área. Por fim, frisa-se esta linha argumentativa e analítica do texto: conceitos ou valores entendidos como fundamentais e constantes na política externa brasileira; características gerais e essenciais da política externa de FHC, Lula e Dilma; e o delineamento da política externa atual, bem como seus desafios.

Suspect detention during the pre-investigation proceedings in Republic of Serbia
Authors: Prica Ljubica
Published: July 2021

According to the Article 27, paragraph 1 of the Constitution of Republic of Serbia (2006), the right to liberty is guaranteed to all domestic and foreign persons, which is derived from the constitutional provision that the holder of this right is "everyone". Everyone has the right to move freely, to settle in Republic of Serbia, to leave it, and to return to it. This freedom may be restricted by law if it is necessary to conduct a criminal proceedings, protect the public order and peace, prevent the spread of infectious diseases, or defense of Republic of Serbia (the Constitution of Republic of Serbia, 2006, the Article 39, paragraph 2). Deprivation of liberty is allowed only for legal reasons and in the procedure provided by law. Both minors and adults may be deprived of their liberty. A person who has not reached the age of 14 is considered a child, and he/she cannot be deprived of liberty in the pre-investigation procedure because, according to our legal regulations, children are not subject to criminal liability. The aim of this paper will be to explore the concept of deprivation of liberty by arresting and/or detaining a suspect in the pre-investigation procedure according to the criminal procedure legislation of Republic of Serbia, with examples from previous practice and a proposal for some legal improvements.
Police subculture and the influence of machismo on women's position in the police
Authors: Subošić Dane , Vranešević Milena
Published: July 2021

The aim of this research was to establish the position of women in the police force regarding the fact that this profession is traditionally considered to be a male working environment, in which it is easy to discern the presence of "machismo". With that in mind, it was necessary to explore the attitudes, values and convictions among the members of the police force, who are a part of the police subculture. For that purpose 90 police officers - male and female, were interviewed in the Police Department in Sremska Mitrovica. The results of the empirical research show that there is an improvement in the field of integration of women in the police force. However, there are still significant differences between male and female respondents when it comes to the comprehension of the competence of women for the police work.

Overtime work as a form of work exploitation
Authors: Kuzminac Mina
Published: July 2021

In the paper, the author analyzes the normative framework that regulates overtime work at the international and national level, but also the issue of overtime work in practice. The author puts forward the thesis that employers resort to overtime work in order to reduce labour costs, and employees agree to work overtime, even when it is illegal, due to the fear of dismissal, so by such abuse by employers, overtime work becomes a form of work exploitation. The author has conducted the research through a survey and an interview in order to determine the extent to which (illegal) overtime work is present in practice. The results of the research show that unpaid overtime work is widely present and that employees are afraid to stand up against this practice. In conclusion, there is a discrepancy between the normative and the real when it comes to overtime work.

Authors: Zhezhova Silvana , Jordeva Sonja , Golomeova-Longurova Sashka , Jovanov Stojanche
Published: July 2021

Medical textile is an extremely important subcategory of technical textile because it is covering a wide range of products. The term medical textile itself covers all types of textile materials that are used in the healthcare system for various purposes. Medical textile is also known as health textile and is one of the fastest growing sectors in the technical textile market. The growth rate of technical textiles in this area is due to constant improvements and innovations in both areas: textile technologies and medical procedures. Textile structures used in this field include yarns, woven, knitted and non-woven textile materials as well as composite materials reinforced with textiles. The number of applications is large and diverse, from simple surgical sutures to complex composite structures for bone and tissue replacement, hygiene materials, protective products used in operating rooms and in the process of postoperative wound treatment. The purpose of this paper is to emphasize the importance of technical textiles for medical, surgical and healtcare applications, to indicate which textiles are currently used in this field.

Authors: Mrdak Mihailo , Lačnjevac Časlav , Rakin Marko , Janaćković Đorđe , Veljić Darko
Published: July 2021

In this paper, studied was the melting of W powder particles in plasma, their behavior at oxidation as well as the mechanism of hardening on the surface of the substrate. Tungsten coating layers were deposited with vacuum plasma spray technology (VPS) on the test specimens of steel Č.4171 (X15Cr13 EN10027). VPS technology has advantages over the APS technology due to decreased oxidation of melted powder particles, by producing a coating with a controlled proportion of micro pores and greater uniformity of the deposited layers. Evaluation of mechanical characteristics of the layers was done by examining the microhardness using the HV0.3 method and tensile bond strength by tensile testing. The microstructures of the deposited layers were analyzed by means of optical microscopy (OM) and scanning electron microscopy (SEM). The results obtained showed that the tungsten coating consisted of well melted particles that interconnected and were overlapping, which shows a typical lamellar microstructure. Present in the microstructure are micro pores in very small proportion at the inter-lamellar boundaries. Tests have shown that layers of W coating deposited by plasma spray in inert gas shielding at low pressure have good mechanical properties and microstructure, which in the fully enables its use in exploitation.

Resultados de la política de formación profesional en España y Alemania
Authors: Soler Guillén Ángel , Pascual Fernando
Published: July 2021

La formación profesional ofrece un itinerario educativo cercano a la realidad del mercado laboral que responde a la demanda social de contar con personal cualificado en los diferentes sectores profesionales y productivos. Este artículo analiza el estado actual de la formación profesional en España y compara su situación respecto de Alemania, caso de éxito gracias a un modelo maduro, consensuado y con una fuerte implicación del sector empresarial. La revisión del marco institucional y legal, así como el reparto de competencias educativas entre el estado central y las regiones, no arroja grandes diferencias entre ambos países. No obstante, el análisis exhaustivo de una serie de indicadores procedentes de Centro Europeo para el Desarrollo de la Formación Profesional (Cedefop) apunta hacia una menor implantación de la formación profesional en España, más acusada en la modalidad dual, que podría atribuirse, entre otros factores, a un menor consenso en las reformas educativas y una insuficiente coordinación vertical y horizontal entre las administraciones y los agentes sociales. Los indicadores analizados muestran el impacto positivo de la formación profesional, reflejado en mayores niveles de inserción laboral, productividad y salarios. El artículo concluye con unas orientaciones de política económica, que señalan los cambios necesarios para que España pueda converger hacia una formación profesional potente y atractiva, en línea con los países de su entorno, y que ejerza como palanca para mitigar las altas tasas de abandono educativo y desempleo juvenil.
Política de empleo: posibilidades y limitaciones
Authors: Benítez-Aurioles Beatriz
Published: July 2021

El objetivo de este artículo es analizar las posibilidades y limitaciones de la política de empleo. Después de algunas consideraciones sobre su contenido y alcance, se aborda, en primer lugar, las políticas que afectan a la oferta de trabajo y, más concretamente, las destinadas a establecer controles o incentivos para regular la población activa. Posteriormente, se discuten las políticas sobre la demanda de trabajo y, en particular, los efectos de las bonificaciones a la contratación y la pertinencia de establecer normas que protejan a los empleos existentes. Por último, respecto a la política que afecta a la formación de salarios, se estudian las consecuencias del salario mínimo y las circunstancias en las que se enmarca la negociación colectiva. A lo largo de la exposición se argumentará que la eficacia de la política de empleo está condicionada, entre otros factores, por la lógica económica y por las restricciones que imponen los marcos institucionales en los que se desarrollan.
Políticas públicas de cuidados de larga duración: residencias para mayores, calidad del servicio y atención de calidad
Authors: Briones Peralta María Ángeles , Pardo García Isabel , Escribano Sotos Francisco
Published: July 2021

En este artículo se presenta una revisión de la repercusión que tendrá el envejecimiento de la población en el aumento de la demanda de cuidados de larga duración, en particular de la atención en residencias para mayores. Estas previsiones y la situación actual de las residencias, especialmente tras la grave situación provocada por la pandemia, hacen necesario un repaso por algunos conceptos imprescindibles como la gestión de calidad, la calidad asistencial, el modelo de atención centrada en la persona o las buenas prácticas. Una consideración muy especial debe tenerse en relación a la formación y condiciones de los profesionales del sector. Todos estos aspectos deberán ser tenidos en cuenta para la elaboración de políticas públicas dirigidas a cambiar el modelo residencial en España.
Kant, Hölderlin, Edipo, Deleuze
Authors: García Ferrer Soledad
Published: July 2021

En este trabajo queremos seguirle la pista a una sugerencia que hace Deleuze en Diferencia y repetición según la cual Kant sería el heredero de Edipo. El Edipo al que nos referimos no es otro que el de la tragedia de Sófocles pero tal como fue interpretado, no por Freud, sino por otro trágico: Hölderlin. Nos interesa saber cuál es la interpretación que hizo Hölderlin, inspirado en su admiración por Kant, del personaje trágico. Nos proponemos, pues, poner en relación los cuatro nombres que aparecen en el título, entre los cuales hemos alcanzado a escuchar el eco de una repetición.
La intuición pura y la representación de conexión (Verbindung) en Kant
Authors: Koch Anton Friedrich
Published: July 2021

El ensayo responde a una crítica de Christian Martin al segundo paso de prueba de Kant en la B-Deducción de los conceptos puros del entendimiento. Martin critica a Kant por permitir de manera inadmisible que la espontaneidad del entendimiento tenga un efecto sobre la intuición pura del tiempo y el espacio, como si pudiera crear la unidad del continuo que Kant había asignado correctamente al lado de la sensibilidad en la Estética trascendental. Por el contrario, el ensayo defiende la siguiente doble tesis a favor de Kant: (1) Aunque, como sostiene Martin, la continuidad del espacio y del tiempo se da independientemente de nuestra espontaneidad, no puede ser conocida receptivamente, sino que debe ser puesta espontáneamente en el proceso de la cognición. (2) Este poner espontáneo sólo puede reconstruir la continuidad de la misma manera que se obtiene independientemente de la reconstrucción. De (2) se desprende que los principios de la reconstrucción postulada, las categorías, ya se aplican independientemente del propio continuo espaciotemporal.

Eastern psychosomatic techniques and modern psychological practices
Authors: Gusev Evgenii Ivanovich , Malikov Vladislav Mikhailovich
Published: July 2021

The goal of this article consists in the analysis of Eastern psychosomatic techniques for determining the possibility of their use in modern psychological practices. The growing interest in the Eastern psychosomatic Buddhist and Taoist practices is observed in the humanities; they are actively implemented in correction of psychological problems that arise among the residents of urban agglomerations. The author demonstrates the interaction between the Russian culture and Eastern civilizations, as well as formulates a thesis on the continuity of cultures of the Eurasian region. The examples of interrelation of the methods of Eastern psychosomatic techniques in the correction of psychological problems of modern individual are described. The article provides the results of empirical study to prove the hypothesis of the possible correlation of psychological problems of an individual by Eastern psychosomatic practices. For acquisition of statistically significant data, the author employs psychosemantic technique, and for verification of the statistical hypothesis – χ2 criterion. The sampling consists of practicing psychologists with over 10 years of experience. In the course of the study, the hypothesis has been proven correct. Practicing psychologists do not have sufficient information for implementing Eastern practices in counseling; however, getting familiar with such practices, consider it promising to synthesize Eastern practices in their work, and indicate psychological effectiveness for solution of the problems of modern individual. Integration of the principles and methods of Eastern practices into psychotherapeutic activity would prompt versatile and comprehensive understanding of the existential problems of personality, as well allow using the acquired knowledge in counseling.

Authors: McGregor Vidette L. , Horn Peter , Dutilloy Adele , Datta Samik , Rogers Alice , Porobic Javier , Dunn Alistair , Tuck Ian
Published: July 2021

The Tasman and Golden Bays (TBGB) are a semi-enclosed embayment system in New Zealand that supports numerous commercial and recreational activities. We present three ecosystem models of the TBGB ecosystem with varying levels of complexity, aimed at contributing as tools to aid in understanding this ecosystem and its responses to anthropogenic and natural pressures. We describe the process of data compilation through to model validation and analyse the importance of knowledge gaps with respect to model dynamics and results. We compare responses in all three models to historical fishing, and analyse similarities and differences in the dynamics of the three models. We assessed the most complex of the models against initialisation uncertainty and sensitivity to oceanographic variability and found it most sensitive to the latter. We recommend that scenarios relating to ecosystem dynamics of the TBGB ecosystem include sensitivities, especially oceanographic uncertainty, and compare responses across all three models where it is possible to do so.

Antifungal therapeutics is confronted today with the challenge of drug resistance of most fungal germs to current antifungal drugs. Faced with this situation, the search for new and more efficient antifungal molecules that avoid the phenomenon of drug resistance becomes an urgent task. The design of new antifungal drugs acting on new biological targets and/or by innovative mechanisms of action is essential in the fight against fungal infections. Current advances in molecular biology have identified new targets for the development of new antifungal therapy. Several biological targets for the development of new antifungal agents are currently being explored. Amongst these, the most promising are BET (Bromodomain and Extra-Terminal) proteins, Homoserine transacetylase (HTA), mannan cell wall, Glycosylphosphatidylinositols (GPI) anchor biosynthesis, Histone deacetylases, Sphingolipid biosynthesis, D9 fatty acid desaturase and Chitin biosynthesis. This review summarizes the new biological targets and their inhibitors under development as potential new antifungal drugs.

The purpose of the study was to investigate the challenges found in the implementation of school guidance services in Ghana. The study was underpinned by pragmatic paradigm where concurrent triangulation mixed method design was used for the study. At the quantitative phase, survey was conducted while multiple case study was also used for the qualitative phase. The total sample for the study was one thousand six hundred and ninety-one (1691) teachers was selected. At the quantitative phase questionnaire were administered to 1679 teachers while 12 headmaster/mistresses were interview at the qualitative phase. It emerged that orientation, counselling and information services should be adequately provided in senior high schools to provide students from indiscipline. Moreover, the study revealed that the location of the teacher-counsellor’s office should be convenient to ensure privacy and confidentiality which would enable students to patronise guidance service. Again, the finding revealed that there should be a clear national policy on funding, allocation of time and role definition of school counsellors to help them carry their duties. The paper highlights comprehensive overview on issues related to the implementation school guidance services.

Published: July 2021

Persistent challenges of potable water supply and its implications hinder man’s progress in Limbe municipality. The growing population of Limbe Municipality faces increasing challenges of potable water supply with lots of implications. And the Cameroon Water Utilities Corporation (CAMWATER) with the local communities involved in potable water management is unable to meet up with this increasing demand.  This has led to the challenges of potable water supply in Limbe municipality which is very frustrating to water consumers. This present study sought to examine the challenges of potable water supply and its implications in Limbe. A combination of research methods (desk review, interviews and reconnaissance field appraisal) have been used in this study. Our findings revealed that increasing population and poor management of potable water supply were the major problems. In the methods utilized, a community based cross-sectional survey was conducted from March to December 2020 using quantitative and qualitative approaches. Wealth Health Organization checklist was used for observation around catchments, then the assessment of water supply challenges was done with a semi quantitative approach. And 200 questionnaires were administered where qualitative data was collected through Focus Group Discussions and in-depth interviews. The results obtained from the 7 water catchments assessed indicated that 50% of the water supply challenges were as a result of the increasing population in Limbe municipality. Meanwhile 30% stated that poor management of potable water supply by the authorities concern is another reason of persistent challenges of potable water supply in Limbe. While 20% were of the opinion that the challenges of potable water supply is as a result of anthropogenic activities near water catchments leading to a progressive reduction in water volume. An integrated potable water management team is needed and a periodic monitoring of these catchment in order to reduce this persistent challenges.

Revisiting the Role of the Triple‐Phase Boundary in Promoting the Oxygen Reduction Reaction in Aluminum–Air Batteries
Authors: Choi Sangjin , Do Hyung Wan , Jin Dana , Kim Sungsoon , Lee Jeongyoub , Soon Aloysius , Moon Jooho , Shim Wooyoung
Published: July 2021

The decomposition, electron transfer, and protonation of oxygen molecules are typically assumed to be the rate‐limiting steps of the oxygen reduction reactions (ORR), and the activation energy barriers of these reactions can be surmounted using catalysts. In this study, the physical rate‐limiting step of the ORR consists of the adsorption of gaseous oxygen molecules at the liquid–solid phase boundary, indicating that the formation of a gas–liquid–solid triple‐phase boundary (TPB) is important for accelerating the ORR kinetics. This is experimentally confirmed by analyzing the ORR in aluminum–air batteries. Moreover, the formation of a TPB using the hierarchical pores of sparked reduced graphene oxide is demonstrated, which serve as the cathode, and the remarkable electrochemical performance of the fabricated battery is presented. These findings can be used to accelerate the ORR kinetics by maximizing the TPB, particularly in aluminum–air batteries.

White light emission is of great importance in our daily life as it is the primary source of light indoor and outdoor as well as day and night. Among various materials and lighting technologies, intensive efforts have been made to quantum dots based‐light‐emitting diode (QD‐LEDs, or QLEDs) because of outstanding optical properties, facile synthesis, and bandgap tunability of QDs. Despite the fact that QLEDs are able to present various colors in a visible range, realizing efficient direct white light emission is a challenge as white light emission can only be achievable through stacking and patterning of QD films or mixing of different sizes of QDs. This inevitably involves energy band mismatch at interfaces, leading to degradation of device performance. Here, a new effective method to improve white QLED performances through embedding a ferroelectric islands structure is introduced, which induces an electric field to effectively modulate the energy band at the junction interface. The formation of a favorable energy landscape leads to efficient charge transport, improved radiative recombination, and consequently high external quantum efficiency in the white QLEDs. In addition, it is demonstrated that this new approach is proved to be effective in different color temperatures ranging from 3000 to over 120 000 K.
Metal‐Catalyzed Reactivity Reversal in the Sulfonylation Reaction of α‐Allenols: Controlled Synthesis of 4‐(Arylsulfonyl)‐2,5‐Dihydrofurans

The synergy between metal catalysis and radical chemistry allows to surpass previous limitations of the reactions between allenols and sulfonylating reagents. Considering that previous studies of the reactivity of the allenol moiety with sulfonylating reagents have been limited to addition and rearrangement reactions lacking cyclization, we decided to modify the protocol for achieving a catalytic cyclization/functionalization. In this way, we accomplished a copper‐catalyzed cascade cycloetherification/sulfonylation for the controlled preparation of 4‐(arylsulfonyl)‐2,5‐dihydrofurans from allenols and sulfinates involving in situ‐generated sulfur‐centered radicals. The generality of our strategy was illustrated using various methyl‐ and phenyl‐substituted allenes.

Achieving high energy storage performance and fast rate capability at the same time is one of the most critical challenges in battery technology. Here, a high‐performance textile cathode with notable specific/areal capacities and high rate capability through an interfacial interaction‐mediated assembly that can directly bridge all interfaces existing between textile and conductive materials and between conductive and active materials, minimizing unnecessary insulating organics is reported. First, amine (NH2)‐ and carboxylic acid (COOH)‐functionalized multiwalled carbon nanotubes (MWNTs) are alternately layer‐by‐layer (LbL)‐assembled onto cellulose textiles for the preparation of conductive textiles using hydrogen bonding interactions. Dioleamide‐stabilized LiFePO4 nanoparticles (DA‐LFP NPs) with high crystallinity and high dispersion stability in organic media are consecutively LbL‐assembled with MWNT‐NH2 onto conductive textiles through ligand replacement between native DA ligands bound to the surface of the LFP NPs and NH2 groups of MWNTs. In this case, 35 nm sized LFP NPs are densely and uniformly adsorbed onto all regions of the textile, and additionally, their areal capacities are increased according to the deposition number without a significant loss of charge transfer kinetics. The formed textile cathodes exhibit remarkable specific/areal capacities (196 mAh g−1/8.3 mAh cm−2 at 0.1 C) and high rate capability with highly flexible mechanical properties.

Stereoselective inhibition of the nucleation and crystal growth of one enantiomer aided by “tailor‐made” polymeric additives is an efficient method to obtain enantiopure compounds. However, the conventional preparation of polymeric additives from chiral monomers are laborious and limited in structures, which impedes their rapid optimization and applicability. Herein, we report a “plug‐and‐play” strategy to facilitate synthesis by using commercially available achiral polymers as the platform to attach various chiral small molecules as the recognition side‐chains through non‐covalent interactions. A library of supramolecular polymers made up of two vinyl polymers and six small molecules were applied with seeds in the selective crystallization of seven racemates in different solvents. They showed good to excellent stereoselectivity in yielding crystals with high enantiomeric purities in conglomerates and racemic compound forming systems. This convenient, low‐cost modular synthesis strategy of polymeric additives will allow for high‐efficient, economical resolution of various racemates on different scales.

Ein bizyklisches Peptid wurde mit einem Diarylethen modifiziert, um lichtschaltbare Inhibitoren der Serinprotease Bos taurus Trypsin 1 (T1) zu erzeugen. Ausgehend von dem Sonnenblumen‐Trypsin‐Inhibitor‐1 (SFTI‐1) als Prototyp, erhielten wir lichtschaltbare Inhibitoren von T1 mit Ki im niedrigen nanomolaren Bereich, deren Aktivität durch Bestrahlung mit Licht um das 20‐Fache moduliert werden konnte. Die inhibitorische Potenz sowie die Resistenz gegen proteolytischen Abbau wurden systematisch an einer Reihe von 17 SFTI‐1‐Analoga untersucht. Die Isomerisierung des Photoschalters beeinflusst das Netzwerk aus Wasserstoffbrücken, das zur Stabilisierung der Struktur der Inhibitoren dient, und möglicherweise auch die Bindungsdynamik zwischen Enzym und Inhibitor. Die Machbarkeit einer zeitlichen und räumlichen Manipulation der Enzymaktivität wurde durch kontrollierten Verdau eines Hydrogels auf Gelatinebasis und eines antimikrobiellen Peptids BP100‐RW bewiesen. Die angewendeten Designprinzipien für Diarylethen‐Photoschalter stellen eine Grundlage für die Entwicklung anderer Serinprotease‐Inhibitoren dar.

The use of poly(2‐ethyl‐2‐oxazoline) (PEOX) in a wet environment is limited because of its high hydrophilicity. In this study, PEOX based blends were prepared via blending PEOX with hydrophobic polymers, such as poly(styrene‐co‐acrylonitrile) (SAN), poly(4‐vinylphenol) (PVPh), and poly(vinylidene fluoride) (PVDF), in order to improve the water‐resistance of PEOX. The blends' water resistance properties are evaluated by the contact angle, solubility, moisture absorption, and mechanical strength in a wet environment. The results show that the water resistance and the adhesion strength of PEOX in a wet environment are dramatically enhanced by polymer blending. The blend with 30 wt% PVPh demonstrates excellent performances in transparency and water‐resistant abilities. It is found that the stable hydrogen bonding within the blend plays an important role in hydrophobic modification. The PVPh/PEOX blend can be applied as a new type of transparent coating or adhesive with enhanced water‐resistant properties in a wet environment.

The SiO2@SiO2:Tb(1,2‐BDC)3phen microspheres with monodispersed core‐shell structure, are kind of fluorescent particles, which are prepared by a seeded growth method under the catalysis of glacial acetic acid (1,2‐BDC, 1,2‐benzenedicarboxylic acid; phen, 1,10‐phenanthroline). Firstly, silica seed was fabricated by the hydrolysis of ethyl orthosilicate, and the Tb(1,2‐BDC)3phen was prepared by using 1,2‐BDC and phen. Then, a thin mesoporous silica shell doped with Tb(1,2‐BDC)3phen was grown on the prepared monodisperse silica colloids. The prepared phosphor was analyzed by Fourier‐transform infrared spectroscopy, X‐ray diffraction analysis, scanning electron microscopy, transmission electron microscopy, thermogravimetric and fluorescence spectroscopy. The experimental results showed that the diameter of the SiO2@SiO2:Tb((1,2‐BDC)3phen microsphere was about 200 nm with a typical core‐shell structure, among which the diameter of the silica core was 180 nm, and that of the mesoporous silicon shell doped with terbium complex was about 10 nm. The fluorescence intensity of SiO2@SiO2:Tb((1,2‐BDC)3phen microsphere is nearly three times higher than that of Tb((1,2‐BDC)3phen complexes. The prepared microspheres could be widely used in bio‐imaging, optoelectronic appliances and medical diagnosis.
