In the present investigation, extended release tablets of metoprolol succinate were developed using cellulose derivatives and natural gums as matrix formers and were evaluated for its extended release characteristics. Th...

"En esta tesis, se estudia el uso de iniciadores multifuncionales para la polimerización en masa de estireno. El objetivo general es desarrollar modelos matemáticos detallados, y a la vez genéricos, que permitan descr...

"Chemical Enhanced Oil Recovery by alkali, surfactant and/or polymer flooding could be o good option to produce remaining oil from brown fields. One parameter that affects performance and economics of a CEOR process is h...

In coastal areas, microplastics (MPs) can deposit in sediment, allowing it to be ingested by benthic organisms, like mussels, thus creating a possible transfer to humans. The aim of this study is to evaluate MPs pollutio...

Abstract Objective Streptococcus agalactiae is an important pathogen in neonates and pregnant women. Neonatal invasive infections due to S. agalactiae are life-threatening and preventive strategies for this challenge o...

This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

We developed a method to graft a tripeptide (glutathione) onto 5-hydroxy-1,4-naphthoquinone, an electropolymerizable molecule. The resulting thin conducting polymer presents a well-defined and stable electroactivity ...

The behaviours of several cationic polyelectrolytes (chitosan; polyquaternium-4; diethylaminoethyl dextran; polyquaternium-10, and aminoacrylmethacrylate copolymer, Eudragit® E100) at a polarised liquid/liquid interface...

Background: Molecular sieves are materials with selective sorption properties, and are used to separate or load mixtures of compounds based on their molecular shape and size. These materials are usually made from porous ...

Abstract Polymer molecular weight plays a central role in determining the balance between electrostatic and steric stabilization in polymer-coated colloidal systems, yet its influence on nanoparticle accessibility at sof...

Influence of weight polymer variation towards sodium fluoride patch physical properties. Fluoride has been proven as a material for strengthen teeth. Many fluoride modalities are available nowadays, and the recent is sod...

Steady-state and time-resolved emission spectroscopy (TRES) of the medium-sensitive probes 4-aminophthalimide (4-AP) and 6-propionyl-2-(dimethylamino)naphthalene (Prodan) were performed at 77 and 298 K in vacuum-sealed t...

Non-toxic biodegradable linear poly(ester-urethane-urea)s with different hydrophilic character were synthesized from poly(ε-caprolactone) as macrodiol, l-lysine diisocyanate (LDI) and ethyl ester l-lysine or l-ornithine...

Abstract Carbon dioxide enhanced oil recovery (CO2-EOR) offers dual benefits of increasing hydrocarbon production and sequestering anthropogenic CO2; however, conventional CO2 flooding suffers from unfavorable mobility r...

Aims: The objective of this work was to study the influence of the sugar source on exopolysaccharide (EPS) production and the activities of the enzymes involved in the synthesis of sugar nucleotides in Lactobacillus case...

The fabrication of photonic and electronic structures and devices has directed the manufacturing industry for the last 50 years. Currently, the majority of small-scale photonic devices are created by traditional microfab...

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...

Abstract The miscibility behaviour of polybenzylmethacrylate (PBMA) blends with polyethylene oxide (PEO) at different compositions has been studied by inverse gas chromatography (IGC). The adequacy of two molecule probes...

Polymerized polypeptide nanomicelles have attracted much attention as novel drug carriers because of their good biocompatibility and degradability. To prepare doxorubicin (DOX)-loaded nanomicelles, an amphiphilic peptide...

The resultsof studies of the effect of nature and parameters of particle size distribution of graphite on physical and mechanical properties of polymer composites based on aromatic polyamide fenіlon C-2. The particle si...

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...

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...

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...
