A biofuel cell is a device for converting chemical energy to electrical energy by a simple way. A high-impact anode is prepared in this research. Here, carboxylated multiwall carbon nanotube (COOH-MWCNT), polydiallyldimethyl ammonium chloride (PDDA) and alcohol dehydrogenase were cast on modified glassy carbon with polymethylene green to construct the bioanode for ...

Nature has evolved materials that possess mechanical properties surpassing many man-made composites. Bones, teeth, spider silk, or nacre, are just a few well-known examples of biomaterials that exhibit exceptionally high tensile strengths, hardness, or toughness. These remarkable properties have driven scientists to study and model their architectures and compositions, from microto nanoscales, ...

Monitoring water quality has become a goal to prevent issues related human health and environmental conditions. In this sense, the concentration of metal ions in sources is screened, as these are considered persistent contaminants. work, we describe implementation customized graphite electrodes decorated with two types Hg nanoparticles (Hg-NPs), optimized toward electrochemical detection Cd, Pb...

Surface chemistry of wood is based on the exposed cut surface that is the combination of intact (lumen wall) and cut cell wall material. It is inherently complex and changes with history of processing. Modification of wood surface through noncovalent attachment of amine containing water soluble polyelectrolytes provides a path to create functional surfaces in a controlled manner. Furthermore, m...

[Ru(bpy)2(PVP)10] (RuPVP (bpy = 2,2-bipyridyl; PVP = poly(4-vinylpyridine)) was synthesized and characterized as described previously. Styrene (MW= 104.15), 2Acetylaminofluorene (2-AAF, MW= 223.27), 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK, MW= 207.23), poly(diallyldimethylammonium chloride) (PDDA, average Mw= 100,000200,000), poly(sodium 4-styrenesulfonate) (PSS, average MW= 70000),...

BACKGROUND Methylxanthines are natural and synthetic compounds found in many foods, drinks, pharmaceuticals, and cosmetics. Aside from caffeine, production of many methylxanthines is currently performed by chemical synthesis. This process utilizes many chemicals, multiple reactions, and different reaction conditions, making it complicated, environmentally dissatisfactory, and expensive, especia...

Responsive polymer thin films play an important role as structural components in the emerging fields of soft actuators, wearable electronics, and biomedical devices. These are capable changing their physical and/or chemical properties significantly response to environmental stimuli, such temperature, light, pH, magnetic fields, ion strength. The integration multifunctional designs networks enab...

Transient Receptor Potential (TRP) channel Melastatin subfamily member 4 (TRPM4) is a broadly expressed nonselective monovalent cation channel. TRPM4 is activated by membrane depolarization and intracellular Ca 2+ , which is essential for the activation. The Ca 2+ sensitivity is known to be regulated by calmodulin and membrane phosphoinositides, such as PI(4,5)P2. Although these regulators must...
