A Cataluminescence Sensor Based on NiO Nanoparticles for Sensitive Detection of Acetaldehyde

open access: yesMolecules, 2020
Sensitive and selective detection of harmful gas is an important task in environmental monitoring. In this work, a gas sensor based on cataluminescence (CTL) for detection of acetaldehyde was designed by using nano-NiO as the sensing material. The sensor

Acetaldehyde exchange above a managed temperate mountain grassland [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
An overview of acetaldehyde exchange above a managed temperate mountain grassland in Austria over four growing seasons is presented. The meadow acted as a net source of acetaldehyde in all 4 years, emitting between 7 and 28 mg C m−2 over the whole ...

Model studies on the pattern of volatiles generated in mixtures of amino acids, lipid oxidation-derived aldehydes, and glucose [PDF]

open access: yes, 2011
The development of flavor and browning in thermally treated foods results mainly from the Maillard reaction and lipid degradation but also from the interactions between both reaction pathways.

Slow-release L-cysteine capsule prevents gastric mucosa exposure to carcinogenic acetaldehyde : results of a randomised single-blinded, cross-over study of Helicobacter-associated atrophic gastritis [PDF]

open access: yes, 2016
Introduction: Helicobacter-induced atrophic gastritis with a hypochlorhydric milieu is a risk factor for gastric cancer. Microbes colonising acid-free stomach oxidise ethanol to acetaldehyde, a recognised group 1 carcinogen.

All You Can Eat Yeast: Substituting Hexose Transporters With AtSWEET7 Alleviates Glucose Repression, Enabling Simultaneous Utilization of Sugars in Renewable Feedstocks

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Yeast sugar transporters have highly evolved for preferential glucose transport, a significant roadblock for utilizing non‐glucose sugars in renewable feedstocks such as lignocellulosic biomass. To enable simultaneous transport of multiple sugars, native hexose transporters were replaced by SWEET7p from Arabidopsis thaliana in engineered ...

A theory for the tissue specificity of BRCA1/2 related and other hereditary cancers [PDF]

open access: yes, 2010
Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery. There has been much conjecture to explain such apparently

Green Hydrogen for Public Transportation: Insights From an ABM and From Palma de Mallorca Case Study

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The development of green hydrogen (GH2) value chains is crucial for decarbonizing sectors such as transport and industry. Their emergence, however, requires coordination among diverse actors, technologies, and regulations, which traditional analytical approaches struggle to capture.

Quantifying Acetaldehyde in Astronomical Ices and Laboratory Analogues: IR Spectra, Intensities, 13C Shifts, and Radiation Chemistry [PDF]

open access: yes
Acetaldehyde is of interest to astrochemists for its relevance to both interstellar and cometary chemistry, but little infrared (IR) spectral data have been published for the solid phases of this compound.

Spectroscopic Insights Into the Role of the Coverage of *CO and *H on Bifurcation of Ethylene and Ethanol Pathways in Carbon Dioxide Electroreduction

open access: yesCarbon Energy, EarlyView.
Zhao et al. control the coverage of *CO or *H intermediates by introducing foreign metal into Cu nanoparticles. The increased *CO coverage on Ag‐doped and Zn‐doped Cu promotes the generation of multi‐carbon products while the increased *H coverage of Co‐doped and Pd‐doped Cu enhances the selectivity of oxygenates. ABSTRACT As key reaction intermediates
