Chemical models of adenine precursors cyanamide and carbodiimide in the interstellar medium [PDF]

Monthly notices of the Royal Astronomical Society, 2023
Cyanamide (NH2CN) and its isomer, carbodiimide (HNCNH), may form adenine in the interstellar medium (ISM) via a series of reactions. Therefore, they are considered key prebiotic molecules in the study of the origin of life.

Stabilized Cu⁰ -Cu¹⁺ dual sites in a cyanamide framework for selective CO₂ electroreduction to ethylene. [PDF]

Nat Commun
Electrochemical reduction of carbon dioxide to produce high-value ethylene is often limited by poor selectivity and yield of multi-carbon products. To address this, we propose a cyanamide-coordinated isolated copper framework with both metallic copper ...

Indium Cyanamide for Industrial-Grade CO2 Electroreduction to Formic Acid

Journal of the American Chemical Society, 2023
Developing industrial-grade electroreduction of CO2 to produce formate (HCOO–)/formic acid (HCOOH) depends on highly active electrocatalysts. However, structural changes due to the inevitable self-reduction of catalysts result in severe long-term ...

1-(4-Aminobutyl)guanidine

Molbank, 2022
Isotope labelling of otherwise endogenous metabolites has emerged as a powerful approach to study metabolism-related biological processes, when used in conjunction with nuclear magnetic resonance or chromatography-supported mass spectrometry.

The use of hydrogen cyanamide or nitrogen fertilizer increases vegetative and productive performance of fig cv. Roxo de Valinhos

Acta Scientiarum: Agronomy, 2021
Some plants do not demand a lot of chilling hours, but methods to overcome dormancy promote more vigorous and productive plant. This study aimed to assess hydrogen cyanamide and nitrogen fertilizer with different concentration to growth and production in

Recent advances in photocatalytic hydrogen peroxide production

PhotoMat, EarlyView., 2023
We classify the representative photocatalytic materials for photosynthesis of hydrogen peroxide (H2O2) in recent years and discuss the related modification methods in detail, providing inspiration and insights for the future design of photocatalysts for H2O2 production.

The Origin of the Feedstock Molecules for Life on the Hadean Earth. [PDF]

Angew Chem Int Ed Engl
The origin of life in the Hadean eon required the formation of amino acids and nucleosides among the key molecules of life. In an often postulated strongly reducing atmosphere, HCN and its derivatives are robustly formed as plausible starting molecules. But HCN does not form in a Hadean, weakly reducing atmosphere.

Comparative pharmacogenetic study of disulfiram or cyanamide efficacy for alcohol dependence: the key role of dopamine neurotransmission gene polymorphisms

Обозрение психиатрии и медицинской психологии имени В.М. Бехтерева, 2023
The actual direction of increasing the efficacy of alcohol dependence (AD) treatment is the search for opportunities for individualization of therapy using pharmacogenetic markers to stratify patients in order to select the most optimal therapeutic ...

Copper(II) Prevents the Saccarine-Dialkylcyanamide Coupling by Forming Mononuclear (Saccharinate)(Dialkylcyanamide)copper(II) Complexes

Inorganics, 2021
The reaction in the system CuII/sacNa(H)/NCNR2 (sacNa(H) = sodium saccharinate (saccharin); R = Me, Et) results in the formation of the complexes [Cu(sac)2(NCNR2)(H2O)2] (R = Me 1, Et 2) instead of the expected products derived from the saccharin ...
