Carbon membranes for efficient water-ethanol separation [PDF]

open access: yesJ. Chem. Phys. 145, 124708 (2016), 2016
We demonstrate, on the basis of molecular dynamics simulations, the possibility of an efficient water-ethanol separation using nanoporous carbon membranes, namely carbon nanotube membranes, nanoporous graphene sheets, and multilayer graphene membranes.

Nitrogen incorporated Zinc oxide thin film for efficient ethanol detection [PDF]

open access: yesarXiv, 2021
Zinc oxide which is a n-type semiconducting metal oxide (SMO) has been a promising material for detecting ethanol vapor. However, pure ZnO based ethanol sensors often suffer from high working temperature, cross sensitivity towards methanol and poor stability against humidity.

The excess wing in the dielectric loss of glass-forming ethanol: A relaxation process [PDF]

open access: yesPhys. Rev. B 62, 8878 (2000), 2000
A detailed dielectric investigation of liquid, supercooled liquid, and glassy ethanol reveals a third relaxation process, in addition to the two processes already known. The relaxation time of the newly detected process exhibits strong deviations from thermally activated behavior.

A exposição pré-natal ao álcool como fator de risco para comportamentos disfuncionais: o papel do pediatra Prenatal alcohol exposure as a risk factor for dysfunctional behaviors: the role of the pediatrician

open access: yesJornal de Pediatria, 2008
OBJETIVO: Ainda que as características clássicas da síndrome fetal alcoólica tenham sido descritas desde 1968, a pesquisa sobre a teratogênese do álcool apenas recentemente demonstrou que o cérebro é o órgão do corpo mais vulnerável aos efeitos da ...

Investigation of the Uniformity of Gel Shrinkage by Imaging Tracer Particles Using X‐Ray Microtomography

open access: yesAdvanced Engineering Materials, EarlyView., 2023
A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Effects of microbial inoculants and amino acid production by-product on fermentation and chemical composition of sugarcane silages

open access: yesRevista Brasileira de Zootecnia, 2012
The objective of this study was to evaluate the chemical composition, fermentation patterns and aerobic stability of sugarcane silages with addition of amino acid production (monosodium glutamate) by-product (APB) and microbial inoculants.

Ethylene Glycol/Ethanol Anolyte for High Capacity Alkaline Aluminum-Air Battery With Dual-Electrolyte Configuration

open access: yesFrontiers in Energy Research, 2020
Aluminum-air batteries (AABs), due to their low cost and high specific capacity, receive much attention nowadays. Nonetheless, a vital problem curbing wide application of AABs is corrosion of the aluminum (Al) anode, which is triggered by hydrogen ...

Pretreatment of Sweet Sorghum Bagasse for Ethanol Production Using Na2CO3 Obtained by NaOH Absorption of CO2 Generated in Sweet Sorghum Juice Ethanol Fermentation

open access: yesFermentation, 2019
(1) Background: Commercial production of fuel ethanol currently uses sugarcane and corn as feedstocks. Attempts to develop other renewable feedstocks that are more abundant have led to lignocellulosic biomass, which requires pretreatment prior to ...

Qualidade pós-colheita de melão 'Orange Flesh' minimamente processado armazenado sob refrigeração e atmosfera modificada Postharvest quality of fresh-cut 'Orange Flesh' melon stored under refrigeration and modified atmosphere

open access: yesRevista Brasileira de Fruticultura, 2004
Melões 'Orange Flesh' minimamente processados foram armazenados por 8 dias sob refrigeração (6 ± 1ºC e 90 ± 5% UR) e atmosfera modificada (passiva e ativas: 5% O2 + 5% CO2 e 2% O2 + 10% CO2).

Energy efficient ethanol concentration method for scalable CO$_2$ electrolysis [PDF]

open access: yesarXiv, 2023
Vacuum membrane distillation efficiently concentrates dilute ethanol streams produced by CO$_2$ electrolysis (CO2R), yielding up to ~40 wt.% ethanol in pure water. Our results allow for a more precise estimation of energy inputs to the separation processes and for the reformulation of CO2R technology development goals.
