A kinetic model for the conversion of dihydroxyacetone (DHA) to methylglyoxal (MGO) in honey is proposed; a building block approach was used to create the model. Artificial honeys doped with DHA and individual perturbants were fitted first, then multiple perturbants (alanine, proline and iron, and combinations of these) were fitted before comparing the simulation to real honey samples (doped cl...

In most flow systems, the rate of protein transfer from bulk solution to a macroscopic surface is site-dependent. In studies on surface-mediated protein conversion, this hampers the comparison of a proposed expression for the conversion process, such as the Michaelis-Menten equation, which actually measured overall conversion rates. However, the rotating disc is a classical example of a uniform...

Conversion-alloying-based materials have been regarded as potential anode electrodes for low-cost sodium-ion batteries (SIBs), but their applications are limited owing to the large volume variation and poor electrochemical kinetics. In this study, Bi2Se3 nanoflowers assembled by ultra-thin na-nosheets, vertically anchored on reduced graphene oxide (rGO) via strong chemical bonding of C–O–Bi, en...

A numerical study is presented aiming to maximize the solar to hydrogen energy conversion efficiency of a mixed culture containing microorganisms with different radiation characteristics. The green algae Chlamydomonas reinhardtii CC125 and the purple non-sulfur bacteria Rhodobacter sphearoides ATCC 49419 are chosen for illustration purposes. The previously measured radiation characteristics of ...

Most resources of natural gas hydrate (NGH) exist in marine sediments where salts and sea mud are involved. It is great importance to investigate the effects on NGH formation kinetics. In this study, mixture silica sand montmorillonite was used mimic mud. The NaCl concentration pore water content methane were studied. A low 0.2 mol/L a range 10–25 wt% beneficial reduce induction time formation....

Porous carbon materials have extraordinary importance as electrodes in many electrochemical devices used for energy storage and conversion. For this reason, there is a growing interest the design of new with improved chemical structural properties that enhance their performance providing high power densities well long cyclability. To satisfy demand, researchers are continuously looking types fu...

Lithium–Sulfur Batteries In article number 2204353, Jeongyeon Lee, Ho Seok Park, and co-workers design triethylene glycol functionalized polymeric cobalt phthalocyanines uniformly coated onto multi-wall carbon nanotubes, which act as an efficient redox mediator in lithium–sulfur batteries. The as-designed materials enable co-operative catalytic lithiophilic sites, facilitating the conversion re...

It is of great interest to understand the nanowelding metallic nanoparticles induced by laser illumination due its potential for offering convenient and controlled means shape-conversion fabrication nanodevices. However, real-time kinetics process were rarely investigated in literature. In this work, we applied fluorescence microscopy directly image silver (AgNPs) shined with continuous wave at...

Despite numerous works devoted to the cellulose hydrogenolysis process, only some of them describe reaction kinetics. This is explained by complexity process and simultaneous behavior different reactions. In this work, we present results kinetic study glucose into ethylene- propylene glycols in presence Ru@Fe3O4/HPS catalyst as a part catalytic conversion glycols. The structure Ru-containing ma...
