Chemical Sites as Catalysts for the Transition to a Circular Economy

Swiss Journal of Business
The chemical industry, often referred to as the “industry of industries”, plays a crucial role in the Circular Economy, an economic model aimed at closing material loops and minimizing harmful environmental impacts.

(Ru-)Mo2C (MXene) catalysts for ammonia synthesis: From Haber-Bosch to chemical looping processes

Materials Today Catalysis
This study investigated (Ru-)Mo2C (MXene) materials for ammonia thermo-catalytic synthesis under atmospheric or moderate pressure. Under a H2-N2 (3:1) flow, the Mo2C MXene phase showed limited activity in ammonia synthesis at atmospheric pressure at 400 °

Four-electron Reduction and Functionalization of N2 by a Uranium(III) Bridging Nitride

CHIMIA, 2018
N2 is a cheap and widely available but very unreactive molecule. Notably, the only industrial process for the conversion of dinitrogen is the Haber-Bosch process to form ammonia, but under very harsh conditions (high temperature and pressure ...

From Mine to Meal: How Critical Minerals Shape the Future of Food

Food and Energy Security, Volume 15, Issue 5, September/October 2026.
ABSTRACT Food systems are increasingly recognised as material‐intensive socio‐technical systems rather than solely biological or land‐based systems. Yet, critical minerals, which underpin both agricultural inputs and emerging clean energy technologies, remain an under‐recognised determinant of modern food security.

Decadal Bowhead Whale Baleen Stable Isotope and Hormone Chronologies (1985–2010) Provide Insight Into Arctic Ecosystem Change

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

Transition Metal Chalcogenides: Perspectives on Their Applications for Nitrate Reduction

ChemistryOpen, Volume 15, Issue 9, September 2026.
This review paper reports the syntheses, properties, and applications of TMCs for electrochemical reduction of nitrate to ammonia. Various studies revealed that the conversion of nitrate to ammonia is principally the electrocatalytic hydrogenation of nitrate and the rate and yield of ammonia is competitively challenged by hydrogen evolution reaction ...

Breeding for Resilient Cereals: Integrating Molecular Networks and Trait‐Based Selection to Improve Nitrogen and Water Use Efficiencies

Plant, Cell &Environment, Volume 49, Issue 9, Page 6583-6595, September 2026.
ABSTRACT Cereal crops are fundamental to global food security, but their production is increasingly challenged by rising demand and the unpredictable impacts of climate change. Among the most limiting and interdependent resources sustaining yields are nitrogen and water.

Rational Design of Trimetallic Alloy for a High‐Performance and Selective Nitrogen Reduction Electrocatalysis

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
The CuAgMo alloy anchored on CNTs can be employed as an electrocatalyst for the nitrogen reduction reaction, exhibiting superior electrocatalytic activity for ammonia synthesis with a Faradic efficiency of 38.8% and long‐term stability of 90 h. Electrocatalytic nitrogen reduction is a vital strategy for green ammonia production. However, this is highly
