The reversible gas phase reaction dinitrogen tetroxide to nitrogen dioxide is very suitable for an integrated physical chemistry project incorporating thermodynamics, statistical mechanics, spectroscopy, and kinetics. Furthermore, nitrogen oxides are molecules of current interest given their important role in atmospheric chemistry. Only relatively common equipment and chemicals are required for...

To limit the impact of food on health issues as obesity, hypertension, or coronary diseases, the reduction of salt or fat content in food products without modifications of organoleptic properties remains a real industrial challenge. A better understanding of the mechanisms involved in release and perception could lead to a better formulation of diet dairy products. In this context, model dairy ...

Our studies of amorphous calcium phosphate (ACP)-based dental materials are focused on the design of bioactive, non-degradable, biocompatible, polymeric composites derived from acrylic monomer systems and ACP by photochemical or chemically activated polymerization. Their intended uses include remineralizing bases/liners, orthodontic adhesives and/or endodontic sealers. The bioactivity of these ...

BACKGROUND Crispness is an important characteristic to be controlled in deep-fat fried products. The physical state of food polymers influences the development of cellular structure and textural qualities of fried food. Glassy state is believed to play an important role in the mechanical properties of low-moisture food. Therefore, an understanding of the physicochemical phenomena in the develop...

Cellular internalization and trans-barrier transport of nanoparticles can be manipulated on the basis of the physicochemical and mechanical characteristics of nanoparticles. Research has shown that these factors significantly influence the uptake of nanoparticles. Dictating these characteristics allows for the control of the rate and extent of cellular uptake, as well as delivering the drug-loa...

The lithium oxygen battery is a promising energy storage system due to its high theoretical energy density and ability to use oxygen from air as a “fuel”. Although various carbonaceous materials have been widely used as a cathode material due to their high electronic conductivity and facial processability, previous studies mainly focused on the electrochemical properties associated with the mat...

The driving idea and the main objective of this synthetic work is study physicochemical factors such as dielectric constant solvent, polarizability chains Gap energy conductive polymers, these characteristics condition their properties. electrical electrochemical. We focused our on polyaniline, two methods are presented: chemical polymerization electropolymerization with emphasis theoretical as...

Inkjet printing is the most widespread technological application of microfluidics. It characterized by its high drop productivity, small volumes, and extreme reproducibility. This review gives a synopsis fluid dynamics inkjet discusses main challenges for present future research. These lie both on printhead side—namely, detailed flow inside printhead, entrained bubbles, meniscus dynamics, wetti...
