The valorization of CO2 appeals to the chemical industry due reduction in greenhouse gas emissions and ability offer more renewable products. Propylene production is second largest process industry, it strongly depends on fossil fuel feedstocks. Coupling with propane dehydrogenation boosts conversion produces CO, a valuable platform currently synthesized by fossil-methane reforming. In this work, (i) we demonstrate environmental benefits coupling life-cycle assessment under industrial...
Pharma-products are mostly single or multiple cyclic compounds. They pollute surface water and persistent in the aquatic ecosystem. When irradiated by UV light, TiO2 catalysts cleave degrade organic contaminants water. Removal of organics photocatalysis results from a synergistic effect adsorption photocatalysis. Synthesis ultrasound (US) produces high area porous solids. Here, we synthesized Mn-doped with US-assisted sol-gel method. Compared to classical synthesis, US increased BET 83 m2...
Specialty chemicals from sugars are destined to displace fermentation alcohols due their superior economic value and atom efficiency. Compared bioethanol, retention of oxygen functional groups increases by 2–5 times the market specialty like furfural, 2,5-furan dicarboxylic acid, 2,5-dimethyl furan, γ-valerolactone. For first time, we report a gas-phase process that converts C-6 monosaccharides furfural in microfluidized bed reactor. A spray nozzle inserted directly into catalytic atomizes...
Biolubricants synthesized from vegetable oils with oleic acid and 1,3-propanediol possess better cold flow properties have a smaller environmental footprint than mineral-based lubricants. However, their synthesis is lengthy (>6 h) requires temperatures above 120 °C. We applied ultrasound (US) to synthesize long-chain diesters (biolubricants): an ultrasonic horn delivered rated powers of 500 750 W at frequency 20 kHz solution 1,3-propanediol. Amberlyst15-H esterified the diester biolubricant....
The first stereoselective synthesis of lippidulcines A, B and C has been accomplished starting from (+)-hernandulcin, which prepared on a multigram scale. previously assigned absolute configurations have confirmed. key steps this are based modified version the Kornblum-DeLaMare rearrangement, highly regioselective ketone reduction with MeCBS reagent. taste evaluations indicate that none these sesquiterpenes sweet, instead lippidulcine A is cooling agent mint after taste.
Abstract Removing solvents from nanoparticle solid suspensions requires the same diligence as drying pharmaceutical ingredients. nanoparticles suspension in water oxidize, sinter, and segregates on surface when they dry a furnace. Spray preserves material properties because contact times are orders of seconds; furthermore, atomized droplets ensure particles small (5 m to 20 m) dispersed. A Yamato GA‐32 (120 mm inner diameter) spray dried co‐current flow water, with content up 60 %....
Abstract Nuclear magnetic resonance (NMR) spectroscopy measures free induction decay (FID) signals that atomic nuclei emit when excited by a radio‐frequency (RF) pulse in static field. The Fourier‐transformed spectrum shows chemically shifted peaks, area intensity, and multiplicity, which give information on molecular structure, bonds, functional groups, purity.

Abstract Wet media mills grind solids to the nanometric size and performance of depends on loading, particle morphology, surfactant concentration, material characteristics. As decreases, they tend form clusters that reduce grinding efficiency. Ultrasound deagglomerates these thereby increasing efficiency but, surprisingly, it can operate at higher concentrations. We processed suspensions (LFP) with a yttria stabilized zirconia from 0.3 mm 0.4 mm, surfactant‐to‐LFP mass ratio 0.008. The...
To meet the objectives of Intergovernmental Panel on Climate Change nations are adopting policies to encourage consumers purchase electric vehicles. Electrification automobile industry reduces greenhouse gases but active metals for cathode—LiCoO2 and LiNiO2—are toxic represent an environmental challenge at end their lifetime. LiFePO4 (LFP) is attractive alternative that non-toxic, thermally stable, durable with a moderate theoretical capacity low electrical conductivity. Commercial...
Abstract This paper presents a study of the conversion pathway acetaminophen (APAP) and amoxicillin (AMO) in water by ultrasound as single degradation method. Results showed that sonication power output, continuous vs. pulsed starting concentration, result different pathways, well simultaneous presence two molecules reduces yield. Hydroquinone hydroxyl‐hydroquinone were detected by‐products, while degraded into four main products. Accordingly, we proposed mechanism finally regressed kinetics...
Abstract The first stereoselective synthesis of peroxylippidulcine A (IIa) and lippidulcines (IIb), B (III), C (IV) is described.
