Efficient fermentable sugar release from softwood biomass is considerably hampered by the recalcitrant nature of its plant cell wall. Here, we reported an ultrasonic and microwave assisted ethylene glycol pretreatment coupled with fast pyrolysis to make total utilization of softwood (pine sawdust) for pyrolytic sugar (levoglucosan), hemicellulosic ...
The periodic low-frequency force can improve mixing efficiency and reduce water constraint, thus intensifying the high solids enzymatic hydrolysis. However, the availability of intensification methods for the periodic force with different frequencies needs to be studied. The periodic high-frequency vibration with rigid spheres added as another inte...

The present work quantifies the impact of fuel chemistry on burning modes using premixed dimethyl ether (DME), ethanol (EtOH) and methane flames in a back-to-burnt opposed jet configuration. The study considers equivalence ratios 0 ≤ Φ ≤ 1, resulting in a Damköhler (Da) number range 0.06 ≤ Da ≤ 5.1. Multi-scale turbulence (Re ≃ 19,550 and Ret ≃ 360...
BACKGROUND: There are no current pharmacological therapies to improve sperm quality in men with sub-fertility. Reducing the exposure to lifestyle risk factor (LSF) is currently the only intervention for improving sperm quality in men with sub-fertility. No previous study has investigated what proportion of men with sub-fertility are exposed to adve...
The Ni catalyst supported on CaO-modified attapulgite (CaO-ATP) were synthesized by wet impregnation method at a constant Ni metal loading (10 wt%). The catalyst was tested by carrying out a glycerin steam reforming reaction under the following conditions: 400-800 degrees C, W/G is 3, GHSV is 1 h(-1). Ni-CaO-ATP exhibited the highest hydrogen yield...

NaOH pretreatment is one of leading technologies for pilot-scale production of cellulosic fuel ethanol. It has two obvious features: low-energy input which is good for its practical application and high wastewater generation which makes it cost too much to avoid environmental pollution. As the methods developed for solving pollution from wastewater...

This paper describes the He non-thermal plasma treatment of liquid impregnated cotton fabrics. The cotton fabrics were soaked in either H2O, D2O or ethanol after which they were placed in an atmospheric pressure parallel-plate DBD reactor. The influence of the used liquid in combination with the plasma exposure time was studied using OES, FTIR, XPS...
