Abstract Understanding and controlling the marine degradation of biodegradable polymers is crucial for sustainable materials engineering and pollution prevention. However, a unified interpretive method that links multisc...

In response to societal demands, the food industry constantly seeks innovations for its products. Active food packaging, developed from biopolymers incorporated with Pickering emulsions, is certainly one of these innovat...

We present the covalent modification of a Pani-like conducting polymer (polyaminobenzylamine, PABA) by grafting of a polyelectrolyte brush (poly [2-(methacryloyloxy)-ethyl-trimethylammonium chloride], PMETAC). As PABA ha...

Core-brush hybrid nanoparticles containing PEG surface functions are highly interesting as biologically inert and smart stimuli-responsive materials for future applications in biosensors, drug delivery, tissue engineerin...

Abstract Campylobacteriosis is a common cause of gastrointestinal disease. In this study, we suggest a general strategy of applying gold nanoparticles (AuNPs) in colorimetric biosensors to detect Campylobacter in chicken...

Amphiphilic comb polymers, like poly(maleic anhydride-alt-1-octadecene) (PMAO), are frequently used to transfer hydrophobic magnetic nanoparticles (NPs) into aqueous media. While it is accepted that the hydrophilization ...

Polymer vascular clips are commonly used in thoracic surgery to ensure secure ligation of pulmonary vessels and are generally considered safe. Clip migration is well described in various abdominal procedures but is extre...

In this research , microwave ray absorbing coating materials had been prepared which work within ( X - band ) frequency i.e 3 cm wavelength . The coating materials were prepared from a mixture of pigmented materials such...

GST-tagged proteins are important tools for the production of recombinant proteins. Removal of GST tag from its fusion protein, frequently by harsh chemical treatments or proteolytic methods, is often required. Thus, the...

Phenolic mercapto oxadiazole and triazole monomers were prepared and then azotized with aniline and Para-phenylene diamine. The prepared monomers have been characterized with FTIR and1HNMR. The six prepared monomers were...

ABSTRACT :         A continuation to a previous study of monosubstiuted transfer agents, carried out by the same author, this investigation had been done. It has been found that multisubstituted chain transfer age...

Abstract Photoinitiated polymerization of methyl methacrylate has been observed using cw-CO2 laser radiation of (10.6 µm). Both of DSC and TGA thermal analysis techniques were used for identification of the thermal char...

Background: Microcin J25 targets the RNA polymerase as well as bacterial membranes. Because there is scarce information on the relationship between the uptake and the activity, a fluorescent microcin J25-derivative was u...

The current technology for lithium extraction from brines is recognized both for its techno-economic disadvantages and its environmental impacts. We have synthesized, characterized, and evaluated particles based on lithi...

In this study, we investigated the thermal stability of polymer networks, which plays an important role in the function of polymer network-liquid crystal composite films. A glass transition temperature of the polymer net...

Abstract The stopping power of α-particles of initial energy 7.69 MeV (emitted from 214Po source) have been measured in the polyethylene(PE) and polypropylene(PP) using surface barrier detector technique and compared wi...

Novel binary liquid crystalline systems were obtained by mixing amorphous side-chain polymethacrylate (SCP) and polar compounds. Their thermal and orientational properties were examined by DSC measurement, polarizing mic...

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 ...

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 ...

When polymers are irradiated with heavy ions new chemical groups are created in a few microns of the material. The irradiation changed the polarity and wettability on the surface so that could enhance the biocompatibilit...

Neonatal sepsis has remained a foremost cause of morbidity and mortality globally, specifically in low- and middle-income countries. The neonatal period, which spans the first 28 days of life, has the highest lifetime ri...

The project is concerned with the preparation of fifteen imines derived from 2-acetyl pyridine ,3 or 4 –hydroxy benzaldehyde and m-anisaldehyde with aromatic primary amines by standard method . These imines include nam...

Inorganic materials contain remarkable properties for drug delivery, such as a large surface area and nanoporous structure. Among these materials, CaCO3 microparticles (CMPs) exhibit a high encapsulation efficiency and s...
