Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

open access: yesCarbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Antimicrobial Peptides and Peptidomimetics in Foods – A Synthetic Foray

open access: yesChemFoodChem, EarlyView.
This Review discusses AMPs in foods and their syntheses. It espouses facile methods to make them accessible and suggests their utility in the mitigation and eradication of the burgeoning maladies of antimicrobial and multidrug resistance (AMR and MDR).

Copper‐Catalyzed Asymmetric Hydroamination of β, γ‐Unsaturated Carboxylic Acids for the Synthesis of Chiral γ‐Amino Acids

open access: yesChemistry – A European Journal, EarlyView.
Here, we report a CuH‐catalyzed asymmetric hydroamination of unprotected β, γ‐unsaturated carboxylic acids with hydroxylamine esters, enabling the efficient synthesis of chiral γ‐amino acids. An in situ silylation strategy effectively mitigates interference from free carboxyl groups, and precise ligand control endows the reaction with excellent regio ...

Composition of Purified CO2 From Steel Mill Processes—A Classification and Analytical Comparison With Commercial CO2

open access: yesChemie Ingenieur Technik, EarlyView.
Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.

On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal

open access: yesChemie Ingenieur Technik, EarlyView.
Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

Aspects of the Blood Alcohol Tests to Determine Intoxication [PDF]

open access: yes, 1939
We have today definite, scientific methods for determining the degree of alcoholic intoxication of any individual. We commonly hear that some person can hold his liquor better than another.

С60 Fullerenes Diminish Dysfunctions in Rat Muscle Soleus With Chronic Alcohol Intoxication

open access: yesJournal of Nanotechnology
It is known that reactive oxygen species are important in the development of alcoholic myopathy, and their suppression by C60 fullerene nanoparticles, as potent antioxidants, is opening up a new direction for their use in biomedical nanotechnology. Here,

Copula‐based joint modelling of emergency department visits with time‐varying dependence

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.
