A green, one-step microwave-assisted polyol synthesis was employed to prepare blue luminescent carbon nitride dots (CNDs) using folic acid molecules as both carbon and nitrogen sources. The as-prepared CNDs had an average size of around 4.51 nm and could be well dispersed in water. Under excitation at 360 nm, the CNDs exhibited a strong blue luminescence and the quantum yield was estimated to b...

─ A new functionality for the hybrid electromagnetic – thermodynamic simulations of microwave heating scenarios in the time domain is presented. The new functionality consists in the modelling of the heated load movement throughout the simulated process. Various types of the movement trajectories have been allowed for, including load rotation and load translation along user-defined piecewise-li...

A pilot plant for continuous flow microwave-assisted chemical reaction combined with microreactors was developed and water heating tests were conducted for evaluation of the developed plant. We developed a microwave apparatus having a single microwave generator that can heat reaction solutions in four reaction fields simultaneously in order to increase throughput. We also designed a four-branch...

The work describes the accelerated enzymatic digestion of several proteins in various solvent systems under microwave irradiation. The tryptic fragments of the proteins were analyzed by matrix-assisted laser desorption/ionization mass spectrometry. Under the influence of rapid microwave heating, these enzymatic reactions can proceed in a solvent such as chloroform, which, under traditional dige...

background: autoxidation is considered to be the main route of edible oil deterioration, which produces undesirable odors and flavors during storage and heating. the unpleasant flavor of oxidized oil has been attributed to primary and secondary products of unsaturated fatty acids. the microwave heating is a rapid method when compared with other methods of heating. objective: in this research, t...

Salmonella Enteritidis culture was subjected to heat or microwave treatment to obtain bacteria reduction by 4, 5, and 6 log units. Control, heated and microwaving micro-organisms were incubated in a nutrient broth at 10°C for 432 h. Growth-curve parameters were calculated using Gompertz and Baranyi equations. It was found that in most cases untreated salmonellae had a shorter generation time, a...

Scale up of microwave sintering for high temperature stable non-oxide ceramics, such as SiC, Si3N4, and dispersion ceramics, like SiC-MoSi2 is still difficult, mainly because of lack of an affordable equipment. For air atmosphere sintering different furnaces were developed, like e.g., gas-microwave hybrid heated tunnel kilns [1] or microwave sintering using an adiabatic casket in tunnel kilns [...

the composite powders of barium-magnesium ferrite were prepared using sol-gel auto-combustion and microwave methods. the crystal structure and the shape of nanocomposites have been compared. x-ray diffraction (xrd), scanning electron microscope (sem) and vibrating sample magnetometer (vsm) were used to investigate the structural, morphological and magnetic properties of nanopowder. the formatio...

The study aims to develop a full-scale plant produce biobased PU foam from microwave liquefaction of riparian shrubs and evaluate its environmental burden using cradle-to-gate, scaled-up LCA approach. Life Cycle Inventory was built on experimental data for polyol synthesis by Response Surface Methodology (RSM) maximize the yield. Bio-based also compared with petrochemical counterpart. Assessmen...
