Preparation of organic hydrazides [PDF]

open access: yes, 1959
Thesis (M.A.)--Boston UniversityDue to the actual high price of hydrazine, this chemical cannot be used in an economical preparation of organic hydrazides. A synthesis of such hydrazides can be envisaged by the reduction of N-nitroamides.

A Ferredoxin Disulfide Reductase Delivers Electrons to the to the Methanosarcina barkeri Class III Ribonucleotide Reductase [PDF]

open access: yes, 2015
Two subtypes of class III anaerobic ribonucleotide reductases (RNRs) studied so far couple the reduction of ribonucleotides to the oxidation of formate, or the oxidation of NADPH via thioredoxin and thioredoxin reductase.

Quantifying Carboxylate Burial in Synthetic Hydrophobic Pockets in Water

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
How “buried” is a buried ion? Double mutant cycles quantify the cost of placing a carboxylate within a deep aromatic calix[4]pyrrole pocket in water. The penalty is only +1.3 to +3.0 kcal·mol−1 because water penetrates through cracks and the portal, creating a wet, high‐dielectric microenvironment.

Seasonal differences and potential biological drivers of the methane paradox in two peri‐Alpine lakes

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Seasonal variations and the biological drivers underlying the methane paradox in freshwater lakes are poorly understood. Here, we investigated the relationship between subsurface methane inventories and phytoplankton in two peri‐Alpine lakes across different seasons.

Viral and metabolic controls on high rates of microbial sulfur and carbon cycling in wetland ecosystems

open access: yesMicrobiome, 2018
Background Microorganisms drive high rates of methanogenesis and carbon mineralization in wetland ecosystems. These signals are especially pronounced in the Prairie Pothole Region of North America, the tenth largest wetland ecosystem in the world ...

3-NOP vs. Halogenated Compound: Methane Production, Ruminal Fermentation and Microbial Community Response in Forage Fed Cattle

open access: yesFrontiers in Microbiology, 2018
The aim of this study was to investigate the effects of 3-nitrooxypropanol (3-NOP) and chloroform on methane (CH4) and H2 production, ruminal metabolites and microbial community structure in cattle fed a tropical forage diet.

Human α2‐Macroglobulin: Architecture, Mechanisms, and Functional Implications

open access: yesThe FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Visual representation of human α2‐macroglobulin in its native and induced conformations. General functions associated with the native form (green), the induced form (white), and both conformations (light red) are indicated. ABSTRACT α2‐Macroglobulin (α2M) is a large glycoprotein and one of the most abundant proteins found in the plasma of vertebrates ...
