The question as to how far the development of chronic diseases in humans depends on diet still remains open. Simultaneously, epidemiological studies suggest the consumption of a flavonoids rich diet might decrease the risk of degenerative changes and certain diseases. The intake of this group of compounds as to quality and quantity depends on dietary habits and a widespread presence of querceti...

The advancement of efficient carbon capture technology is vital for the transition to a net-zero future. Critical developments in ultrasonic irradiation can be used enhance conventional CO2 absorption process. For example, sonophysical effects such as acoustic streaming, cavitation, fountain and atomization induced by propagation high-frequency waves liquid medium mixing create larger interfaci...

nanocomposites based on vinyl ester resin (derakane 470-300) and nano clay (cloisite 30b) were prepared. the effect of clay content of 1, 3 and 5% (by weight) on the morphology, mechanical properties and water absorption of vinyl ester resin nanocomposites were studied. the nanocomposites were characterized  using  small-angle x-ray  scattering  (saxs),  feld  emission  scanning electron micros...

A compact extended cavity diode laser (ECDL) system operating at 852 nm for small optically pumped cesium (Cs) beam frequency standards was reported. ECDL and a saturated absorption spectroscopy setup were all built in an aluminum box with dimension of 10 × 10 × 7 (cm). ECDL was based on a LittmanMetcaff configuration, whose free-running linewidth was less than 600 kHz. A digital automatic freq...
