Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

open access: yesFlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

Degradation of Polyhydroxyalkanoate (PHA): a Review [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2017
Polyhydroxyalkanoate (PHA) is an attractive material due to its mechanical properties and biodegradability. As a result of its ability to degrade naturally in the environment, utilization of PHA is a step closer towards a greener environment with the aim

Microbial PHA biosynthesis and its biomedical applications

open access: yes, 2009
Polyhydroxyalkanoates (PHAs), are polyesters of 3-, 4- 5- and 6-hydroxyalkanoic acids, produced by a variety of bacterial species under nutrient-limiting conditions with excess carbon[1]. PHA production by Bacillus cereus SPV and Pseudomonas sp. has been

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.

Habitat use governs distribution patterns of saprophagous (litter-transforming) macroarthropods - a case study of British woodlice (Isopoda: Oniscidea)

open access: yesEuropean Journal of Entomology, 2012
Despite the importance of saprophagous macroarthropods as key facilitators of plant litter decomposition within ecosystems and their likely sensitivity to global climate change and land-use change, a lack of ecological data has precluded attempts to ...

Polyhydroxyalkanoate (PHA) production from waste

open access: yes, 2003
PHA (polyhydroxyalkanoate) production was attempted with SBRs from food waste. Seed microbes were collected from a sewage treatment plant with a biological nutrient removal process, and acclimated with synthetic substrate prior to the application of the ...

Corrosion Performance of Steel and Zinc‐Based Materials in Diverse Unsaturated Soils: Insights From a 2‐Year Field Exposure

open access: yesMaterials and Corrosion, EarlyView.
The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Mutants deficient on polyhydroxyalkanoate (PHA) accumulation and construction of recombinants to control monomer composition on PHA

open access: yes, 2010
Pseudomonas putida produz PHA de cadeia média (PHAMCL) a partir de carboidratos e óleos vegetais. Genes de biossíntese de P3HB (poli-3-hidroxibutirato) de Ralstonia eutropha foram inseridos em P. putida IPT046 selvagem e mutantes PHA-.
