The aim of this study was to evaluate the effectiveness microwave-assisted extraction (MAE) as an environmentally friendly approach compared conventional heat-reflux (CE) for isolation fennel (Foeniculum vulgare Mill.) seed polyphenols and assess bioactivity obtained extracts. Water, ethanol (30%, v/v) acetone were used solvents, carried out varying temperature (40, 60 80 °C), irradiation time ...

The fatty acid photodecarboxylase from Chlorella variabilis NC64A (CvFAP) promotes the elimination of CO2 acids (Cn) producing corresponding hydrocarbon (Cn-1). Therefore, this enzyme is great biotechnological interest since it can be used in alternative biofuel production routes matching concept green chemistry. However, due to its recent discovery, reaction still requires optimizations, which...

The exopolysaccharide (EPS B3-15) and biosurfactant (BS B3-15), produced by the marine Bacillus licheniformis B3-15, were recently reported to possess different antibiofilm activities, with EPS being more active in preventing adhesion of Pseudomonas aeruginosa Staphylococcus aureus BS destroying their preformed biofilms on surfaces. In this study, synergistic effects two exopolymers bacterial b...

Abstract Molybdenum dialkyldithiocarbamate (MoDTC) is widely used as a friction modifier in engine lubricating oil. Under MoDTC lubrication, the and wear behaviors of tungsten-doped diamond-like carbon (W-DLC) films annealed at 100–400 °C were discussed evaluated using scanning electron microscopy (SEM), atomic force (AFM), Raman spectroscopy. (polymerized alpha olefin) PAO + coefficient all sa...

The purpose of this study was to investigate the effect of weighted jump squat training with and without eccentric braking. Twenty male subjects were divided into two groups (n = 10 per group), Non-Braking Group and Braking Group. The subjects were physically active, but not highly trained. The program for Non-Braking Group consisted of 6 sets of 6 repetitions of weighted jump squats without re...

Enhanced resistive memory characteristics with 10,000 consecutive direct current switching cycles, long read pulse endurance of >10 cycles, and good data retention of >10 s with a good resistance ratio of >10 at 85°C are obtained using a Ti nanolayer to form a W/TiOx/TaOx/W structure under a low current operation of 80 μA, while few switching cycles are observed for W/TaOx/W structure under a h...

The effect of thermal aging homogenized Fe-Au and Fe-Au-W alloys, irradiated at room temperature with hydrogen ions, was studied for an treatment 300 °C times up to 100 h. behavior the Fe-based alloys is compared results pure Fe. precipitation Au-rich W-rich precipitates its correlation H+ irradiation-induced defects investigated by variable energy positron annihilation spectroscopy (VEPAS). fo...

Enhanced resistive memory characteristics with 10,000 consecutive direct current switching cycles, long read pulse endurance of >105 cycles, and good data retention of >104 s with a good resistance ratio of >102 at 85°C are obtained using a Ti nanolayer to form a W/TiOx/TaOx/W structure under a low current operation of 80 μA, while few switching cycles are observed for W/TaOx/W structure under ...
