This method involves using a substance which has a strong affiliation with the water vapour in the air as a solid adsorbent, or liquid absorbent, to remove water vapour from the air. upon contact with the absorbent (adsorbent), water vapour is taken into the liquid absorbent via diffusion or...
Batteries are also periodically discharged and recharged, and when charging, a portion of the water is used by the battery. The liquid levels in the cells must thus be monitored, and if necessary, water should be given to depleted cells in accordance with the manufacturer’s instructions. Accor...
Liquid-liquid extraction is an important unit operation in chemical engineering. The conventional designs such as mixer settler have lower-energy efficienc... PV Hule,BN Murthy,CS Mathpati - International Journal of Chemical Engineering,2012,(2012-5-30) 被引量: 1发表: 2012年 Square Root Extracto...
Using the conservation of mass law, the char and liquid fractions were weighed once the pyrolysis process had occurred and subtracted from the initial sample weight in order to obtain a weight for the gaseous fraction. The sample weights of all phases were converted into a percentage of the ...
Preparation of low-molecular-weight plant extracts About 20 g fresh cabbage leaves were homogenized in liquid nitrogen, and the powder was resuspended in 100 ml water. The extract was centrifuged, fractionated in series by 0.45 µm filter membrane, ultrafiltration membranes YM10 and YM1 to ...

The inside is evacuated, and water or ethanol/water solution is selected as the working fluid. The aluminum plate-like fin is attached with a commercial PV module. By receiving solar insolation, working fluid boils and pushes steam with liquid particles to the condenser. The boiling behavior is...
The bacterial culture of strain 814/98 was initiated from a single colony and grown for 24 h in Luria Broth liquid medium on a rotary shaker at 28 °C and 200 rpm. Total genomic DNA was extracted using the DNA Genomic-tips 100/G kit (Qiagen, Germany), as per the manufacturer’s inst...
(3)φ(%)=mnpvnp+vbfx100%Where φ is the nanofluid concentration; mnp is the mass of the nanoparticle; vnp and vbf are the nanoparticle volume and the base liquid volume, respectively. Magnetic stirring was used in the study to guarantee uniform dispersion of nanoparticles in a base liquid....
Moreover, the phosphorylation of the histidine residue H229 was directly confirmed through liquid chromatography mass spectrometry (LC-MS/MS) analysis following tryptic digestion of the protein (Fig. S12). To assess the role of histidine phosphorylation in enzyme activation, we introduced a mutation ...
