The latest developments in the field of materials to improve the physical and chemical properties is the use of physical modification of polymeric materials. The specimens of polyepoxy and composites on the base metal ox...

The purpose of this work was to investigate the interaction of graphene-like nanoclusters with fragments of polymers of the same nature, but of a slightly different structure, for example, polyethylene (PE) and polypropy...

By the method of microarc oxidation for different types of electrolytes (which include KOH, Na2SiO3, Н2О2, NaOH, NaAlO2, Na5P3O10, NaF) and electrolysis conditions, multifunctional ceramic coatings on a magnesium alloy...

Polystyrene (PS) is generally considered as a passive optical material that is transparent to light with wavelengths longer than 300 nm. In practice, PS micro- and nanospheres with uniform sizes are usually used to buil...

Abstract Microplastic pollution in freshwater is a global concern, yet field monitoring often lacks standardization, hindering data comparability and analysis. This systematic review bridges the gap between lab findings ...

Elastomeric conductive textiles are promising for wearable electromagnetic shielding, requiring maintained performance under stretch. Herein, weft-stretch conductive woven fabric integrating silver-plated elastic wrapped...

Aluminum alloys are commonly subjected to chromatization to improve adhesion and protect against corrosion. However, this process is harmful to health and the environment. In this context, hybrid organic–inorganic sila...

This study evaluates the low-velocity impact response of aerospace-grade epoxy laminates (M18/1) interleaved with four distinct thermoplastic films (PEI, PES, PSU, PC). Impact performance was correlated with quasi-static...

This study employs molecular dynamics (MD) simulations to systematically investigate the effects of the degree of polymerization (DP 10, 20, and 35) on the mechanical and tribological properties of nitrile butadiene rubb...

Tertiary fatty amide, N,N-dibutyldodecanamide (DBDA), has been synthesized and evaluated as a new environmentally friendly plasticizer for polyvinyl chloride (PVC). Homogeneous PVC/DBDA films containing from 10 to 40 w...

Tesis Energía y Ambiente (maestría) - Instituto Tecnológico de Buenos Aires, Buenos Aires - Karlsruher Institut für Technologie, Karlsruhe, 2024 "Fibre reinforced polymers (FRP) used in outdoor applications are expos...

Benzocaine (BZC) is an ester-type local anesthetic used mainly in topical, dermal and mucosal formulations. The present work consists of the development and validation of analytical methodology for evaluation of benzocai...

The solubility behaviour of drugs remains one of the most challenging aspects in formulation development. Solid dispersions (SD) and inclusion complexes (IC) are two of the most promising strategies to improve the oral...

The main objective of this work was to obtain biodegradable nancomposites from polycaprolactone and bentonite with optimized mechanical properties by the chemical modification of the clay (cation exchange reactions). Fir...

Neste estudo, comprimidos matriciais de captopril foram desenvolvidos utilizando-se hidroxipropilmetilcelulose (HPMC) e quitosana (QTS) em diferentes proporções (50:50, 60:40, 40:60, 20:80), por compressão direta. Os ...

A biphasic gastroretentive drug delivery system of acyclovir consisted of loading dose tablet and floating multiple matrix tablets was prepared by direct compression process. The delivery system was designed by hydroxy...

Diclofenaco foi associado a nanocápsulas e a nanoesferas, preparadas através do método de nanoprecipitação, utilizando poli(e -caprolactona) (PCL) ou Eudragit S90® (EUD) como polímeros. As suspensões obtidas fora...

Chitosan is increasingly used as an alternative to synthetic polymers due to its water solubility, biodegradability, and biological activity. In this work, chitosan samples from three suppliers were evaluated and charact...
