Palm oil is a promising raw material for biofuel production using the simultaneous catalytic mechanism of bifunctional cracking-deoxygenation reactions. Through process, chains palmitic acid and oleic in palm were converted to diesel-range hydrocarbons. The combination effects CaCO3 HY zeolite enhanced into biofuel, because increasing basic sites catalysts due synergistic roles HY. introduction...

A solid super acid WO3/SO42--ZrO2–TiO2 catalyst was prepared with adjustable acidity via double bridge connection strategy for oxidation of cyclohexene (CHE) to adipic (AA). XRD, SEM and N2 adsorption-desorption isotherm indicated that WO3 successfully decorated highly dispersed on SO42--ZrO2–TiO2 surface. An obvious stretching vibration peak (1125-1055 ​cm−1) in FT-IR illustrated effect betwee...

Metal confinement catalyst MoS2/[email protected]%Ti (TD, TS-1/Dendritic mesoporous silica nanoparticles composite) in dendritic hierarchical pore structures was synthesized and showed excellent sulfur-resistance performance stabilities catalytic hydrodesulfurization reactions of probe sulfide molecules. The combines the concepts Pt-confinement effect hydrogen spillover Pt noble metal. modified...

BACKGROUND Acetylation of the xylan backbone was a major obstacle to enzymatic decomposition. Removal of acetyl groups by acetyl xylan esterases (AXEs) is essential for completely enzymatic hydrolysis of xylan. Appended carbohydrate binding modules (CBMs) can promote the enzymatic deconstruction of plant cell walls by targeting and proximity effects. Fungal acetyl xylan esterases are strictly a...

Objective(s) Sonodynamic therapy is a physical treatment which utilizes ultrasound waves with an appropriate sensitizer such as protoporphyrin IX (PpIX). The activation of sensitizer depends on cavitation, and therefore, high intensity ultrasound is an important necessity. Beside, high intensity ultrasound can induce side effects on the healthy tissues which have surrounded tumor. The particle...

Reduction of extensive CO2 emissions is one the key challenges that our society must overcome in order to minimize effects global warming and climate change. In this respect, electrochemical reduction via redox enzymes believed be a promising route concentrations, as they specifically catalyze selective reversible way at low potentials mild conditions. work, we describe effective anchoring enzy...

This research attempts to find a new approach for the removal of arsenic (As) from drinking water by developing novel solution. To author’s knowledge, iron-loaded activated carbons (Fe-AC) have not been previously applied As in synergistic process using ozonation and catalytic processes. The was investigated samples different areas Lahore, Pakistan, compared with without catalysts. results also...

The goal of this work was to investigate a possible synergistic effect between ethanolic extracts of propolis from Brazil and Bulgaria and some antibiotics (Amoxicillin, Ampicillin and Cefalexin) against Salmonella Typhi. Brazilian and Bulgarian propolis showed an antibacterial action, but the sample from Bulgaria was shown to be more efficient. Both samples showed a similar synergistic effect ...

7-ethyl-10-[4-(1-piperidyl)-1-piperidyl] carbonyloxy-camptothecin, a topoisomerase I (topo I) inhibitor, is one of the most active agent against lung cancer, and its radiosensitizing effect has been reported recently. We evaluated a combination in vitro effect of irradiation and 7-ethyl-10-hydroxy-CPT (SN-38), an active metabolite of 7-ethyl-10-[4- (1-piperidyl)-1-piperidyl] carbonyloxy-camptot...
