Carboxylic ligands and their influence on the structural properties of PbTe quantum dots.

PLoS ONE
We present a low-cost, straightforward, and tunable hot-injection method for synthesizing PbTe quantum dots (QDs). By incorporating short-chain carboxylic acids-hexanoic acid (HexA), heptanoic acid (HepA), and acetic acid (AcA)-alongside oleic acid (OA),

Chemical and Quality Changes in Natural Green Manzanilla Olives: Impact of Preservation, Brine, and Storage

Journal of Food Science, Volume 91, Issue 8, August 2026.
ABSTRACT This study evaluated the effect of different storage conditions on the chemical (pH, acidity, organic acids, polyols, phenolic compounds, and volatilome) and quality characteristics (surface color, brine color, and firmness) of natural green Manzanilla table olives.

7-(Disubstituted thiazolyl)-3,5-dihydroxy-6-heptenoic/heptanoic acid derivatives as HMG-COa reductase inhibitors

, 1994
A series of disubstituted thiazole, functionalized with the essential 3,5-dihydroxy-6-heptenoic or heptanoic chain, were prepared and evaluated in vitro as HMG-CoA reductase inhibitors.

The alimentary impact of the hemp seed [PDF]

, 2013
Hemp seed and hemp seed oil can supply us with many important substances. Their essential fatty acid compositions are favourable, but they may contain non-psychotropic cannabinoids. Emerging data show that these components can influence the health status

Evidence That Parietal Lobe Fatty Acids May Be More Profoundly Affected in Moderate Alzheimer’s Disease (AD) Pathology Than in Severe AD Pathology

Metabolites, 2018
Brain is a lipid-rich tissue, and fatty acids (FAs) play a crucial role in brain function, including neuronal cell growth and development. This study used GC-MS to survey all detectable FAs in the human parietal cortex (Brodmann area 7).

Flowzonolysis: Continuous Oxidative Ozonolysis of Algae‐Derived Palmitoleic Acid for the Synthesis of Azelaic Acid

Chemistry–Methods, Volume 6, Issue 7, July 2026.
Flowzonolysis enables the continuous oxidative cleavage of algae‐derived palmitoleic acid to azelaic acid in a single integrated process. By combining alkene cleavage and oxidation without isolating reactive intermediates, this method minimizes auxiliary reagents, improves atom economy, and supports safer, more sustainable diacid production from ...

Structure–activity relationship study shows versatility in substrate specificity for heterodisulfide reductase in methanogenic archaea

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Hydrogenotrophic methanogens are anaerobic archaea that convert carbon dioxide and hydrogen into methane. Central to this process is the heterodisulfide reductase (Hdr), which catalyzes the reduction of the heterodisulfide made of coenzyme M and coenzyme B. In vivo, Hdr functions in association with electron‐donating modules such as the [NiFe]‐
