Enzyme-induced carbonate precipitation (EICP) is a biocementation technique that produces comparatively fewer carbon dioxide emissions than traditional cementation. However, the use of synthetic reagents for EICP costly, and process an ammonium byproduct water pollutant. This study utilized fresh human urine as source urea calcium-rich zeolites adsorbent calcium ions cementation technique. Batc...

Synthesis of YSZ nanopowder by alkoxide sol-gel method, through two different hydrolysis routes, one under careful control by using acetyacetone as ligand, and the other through basic hydrolysis, was investigated. The synthesized powders were characterized by various analytical techniques such as, XRD, STA, PSA, BET, SEM, and TEM. The results showed that, the YSZ powders prepared through the ba...

The efficiency of ammonia removal from fresh source-segregated domestic food waste digestate using biogas as a stripping agent was studied in batch experiments at 35, 55 and 70°C, at gas flow rates of 0.125 and 0.250Lbiogasmin(-1)L(-1)digestate with and without pH adjustment. Higher temperatures and alkaline conditions were required for effective ammonia removal, and at 35°C with or without pH ...

China experienced severe haze pollution in the past decades. However, systematic characterization of atmospheric fine particles with advanced measurement techniques has been very scarce Shanghai, which is largest megacity China. Herein, we present non-refractory submicron aerosol (NR-PM 1 ) urban Shanghai during winter 2017 by applying an Aerosol Chemical Speciation Monitor (ACSM, Aerodyne Rese...

Protein hydrolysate is highly regarded as a source of naturally occurring antioxidant peptides. The purpose of this study was to investigate the effect of Ultrasonic (Frequency, 20 KHz; Amplitude, 50%; Time, 30 min) and high-pressure homogenization (Power, 1500 bar; Rated flow, 10 dm/h) pretreatmenton the enzymatic hydrolysis and antioxidant properties of yeast protein hydrolysate obtained from...

Robinson, Birnbaum, and Greenstein (1) in 1953 accomplished the isolation of renal aminopeptidase from fresh hog kidney by extracting the activity from the particulate fraction of kidney homogenate with I-butanol and thereafter fractionating between 50 and 75% saturation with ammonium sulfate at pH 7. About 30% of the final product was extractable by organic solvents, the extractable material a...

Anaerobic digestion (AD) is a key technology at many wastewater treatment plants (WWTPs) for converting primary and surplus activated sludge to methane-rich biogas. However, the limited number of surveys lack comprehensive datasets have hindered deeper understanding characteristics associations between variables microbial community composition. Here, we present six-year survey 46 anaerobic dige...

Ionosilica nanoparticles are original ionic nano-objects at the interface of liquids and mesoporous silica. nanoparticles' synthesis was achieved via sol-gel procedures exclusively from trialkoxysilylated precursors without any silica source. However, knowledge about main parameters for a controlled ionosilica remained fragmental so far. In this work, we present systematic study nanoparticle fo...

the hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of h+ to nabh4. the sulfonated porous carbon (spc) is used as a source of hydrogen ion and catalyst. it is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of nabh4 to generate hydrogen gas at room temperature in comparison to amberlyst-15 and nafion-nr50. the ki...
