SYNTHESIS AND APPLICATION OF PMMA EMULSION FOR COATING MEDICAL NATURAL LATEX GLOVES
Authors: Zhang Chengye , Yuan Yizhong , Sun Jinyu , Zhang Yao , Tian Xiaohui , Cai Chunhua 
Published: January 2025

ABSTRACT
Natural latex gloves are prone to allergies and adhesion during use. Corn starch and talc, while improving adhesion, do not solve the allergy problem. These powders even increase allergy transmission pathways as well as create safety hazards such as granulomas. Depositing polymethylmethacrylate (PMMA)-chitosan (CS) on glove surfaces improves surface adhesion and does not become airborne like powders. However, the physical stability of the film formed by PMMA-CS deposition leaves much to be desired, and azobisisobutyronitrile (AIBN) and hexadecane present safety hazards. To ameliorate these problems, PMMA-CS was prepared by replacing AIBN and hexadecane with tween-80 and β-cyclodextrin, and PMMA-TOFA was prepared by using methyl methacrylate (MMA) and tall oil fatty acid (TOFA). The sulfur-prevulcanized natural rubber (SPNR) films deposited with PMMA-CS and PMMA-TOFA (PMMA CS/PMMA-TOFA/SPNR) had fewer safety hazards, higher roughness and physical stability. It is expected that PMMA emulsion can be applied to the inner and outer surfaces of medical gloves to reduce the safety hazards that exist in medical gloves.
IMPACT OF 1-BUTYLPYRIDINIUM BROMIDE–MODIFIED GRAPHENE NANOPLATELETS ON THE PROPERTIES OF SBR NANOCOMPOSITES
Authors: Joseph Subin , Francis Bejoy 
Published: January 2025

ABSTRACT
It is essential to achieve a strong interfacial interaction between the filler and polymer matrix for the production of polymer nanocomposites with superior performance. Ionic liquid (IL) 1-butylpyridinium bromide (BPB) was used for the surface modification of graphene nanoplatelets (GnPs). The modified GnP (PMG) was characterized using Fourier transformation infrared spectroscopy, Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), and thermogravimetric analysis. BPB functioned as an intermediary between GnP and SBR via noncovalent interactions and promoted GnP dispersion in the SBR matrix. TEMs demonstrated that IL facilitates the homogeneous dispersion of PMG in the SBR/PMG nanocomposites. Dynamic mechanical analysis was used to understand viscoelastic behavior of the nanocomposites. The fraction of immobilized rubber chain around the PMG in the nanocomposites was obtained from the differential scanning calorimetric curve. The SBR nanocomposite prepared shows an improvement of 273% in tensile strength and 12.1 °C in degradation temperature.
CONTRIBUTION OF CROSSLINK NETWORK STRUCTURE TO THE VISCOELASTIC CHARACTERISTICS OF EPDM: TUNING DYNAMIC PROPERTIES THROUGH HYBRID CURING
Authors: Parathodika Arshad Rahman , Aziz Barkat , Naskar Kinsuk 
Published: January 2025

ABSTRACT
EPDM is the fourth most widely used general-purpose elastomer, accounting for approximately 10% of total synthetic rubber production. With its broad applications in the automotive and construction industries, the analysis of EPDM’s dynamic viscoelastic properties is critical for optimizing product performance. Although the effects of various fillers and their structures on EPDM’s viscoelastic behavior have been widely studied, the impact of crosslink network architecture on long-term viscoelastic properties is seldom explored. To investigate the influence of different crosslink types and their compositions on the long-term viscoelastic behavior of EPDM, we have used thiol-amine analysis, time–temperature superposition for frequency-dependent properties, and temperature scanning stress relaxation. We establish correlations between crosslink features and the viscoelastic properties of carbon black–filled EPDM. In addition, we explore the effects of unique crosslink networks formed through hybrid cure systems containing accelerated sulfur and peroxide on the viscoelastic performance of EPDM. Our findings indicate that the frequency dependence of viscoelastic properties is governed by crosslink length, whereas temperature dependence is influenced by crosslink type. The results also indicated a strong correlation between plateau modulus and polysulfide crosslinks. These insights offer valuable guidance for optimizing the viscoelastic characteristics of next-generation elastomeric materials.

Objective: Indonesia ranks third as the country with the most social media users, with emerging adults making up the largest group. On average, Indonesians spend almost 6 hours a day playing social media. This condition can cause both physical and psychological problems. One of the impacts of excessive social media use is Social Media Fatigue (SMF). The level of SMF is influenced by several factors, one of which is Fear of Missing Out (FoMo), which is a fear of missing out on experiences that others are enjoying. SMF and FoMo can significantly impact an individual's mental health. The link between the two conditions is clear, but there is little in-depth research linking the two. This study aimed to explore the association of Fear of Missing out (FoMo) with Social Media Fatigue (SMF) among emerging adults. Method: A cross-sectional study design was conducted among 157 men and women emerging adults. Participants completed a self-administered questionnaire that consisted of demographic characteristics, Fear of Missing Out scale, and Social Media Fatigue scale. Data were analyzed using descriptive analysis and Pearson Correlation statistic technique. Results: Descriptive analysis results showed that men showed a higher tendency of both fear of missing out and social media fatigue compared to women. Further, a significant yet moderate correlation was found between FoMo and SMF among emerging adults. Novelty: This study contributed to explore further on the relationship between fear of missing out (FoMo) and social media fatigue specifically among emerging adults.

Статья посвящена исследованию значения менеджмента медицинской организации в результативности профилактических мер на примере стоматологической помощи. Исследуются причины недостаточной профилактической направленности современной системы здравоохранения. Проводится обзор научных данных, подтверждающих актуальность пересмотра подхода к практической реализации превентивных мер как в государственных, так и в коммерческих медицинских структурах. Изучено влияние способа тарификации оплаты за медицинские услуги, пропорционального их объему, на мотивированность профессиональных организаций и врачей-специалистов к профилактическим манипуляциям. Ставится вопрос о необходимости разработки альтернативных экономических методов мотивации к активному маркетингу и реализации превентивных медицинских технологий. Акцентировано внимание на неравнозначной роли ответственности за личное и общественное здоровье в эффективности дентальной профилактики. Отмечена высокая значимость квалифицированных медицинских мер, которые реализуются медицинской организацией в осуществлении стоматологической профилактики (в отличие от домашних способов индивидуальной профилактики). Сделаны выводы о необходимости разработки цифровых технологий оптимизации менеджмента профилактики для клинических специалистов и руководителей медицинских организаций. Разработка и внедрение методов менеджмента профилактики является актуальной задачей экономических структур, осуществляющих внешнее и внутреннее управленческое консультирование как профессиональную деятельность.
The article is devoted to the study of the importance of medical organization management in the implementation of effective preventive measures using dental care as an example. The reasons for the insufficient preventive focus of the modern healthcare system are investigated. A review of scientific data confirming the relevance of revising the approach to the practical implementation of preventive measures in both public and commercial medical structures is conducted. The influence of the method of tariffing payment for medical services, proportional to their volume, on the motivation of professional organizations and medical specialists for preventive manipulations was studied. The question of the need to develop alternative economic methods of motivation for active marketing and implementation of preventive medical technologies is raised. Attention is focused on the unequal role of responsibility for personal and public health in the effectiveness of dental prevention. The high significance of qualified medical measures implemented by a medical organization in the implementation of dental prevention is noted, in contrast to home methods of prevention. Conclusions are made on the need to develop digital technologies for optimizing prevention management for clinical specialists and heads of medical organizations. The development and implementation of prevention management methods is a pressing task for economic structures that carry out external and internal management consulting as a professional activity.
