Electrocatalytic N2 reduction reaction (NRR) represents an appealing solution for sustainable ammonia production, whereas exploring high-efficiency NRR catalysts is highly desired but extremely challenging. Herein, we combine Ti3C2Tx-MXene quantum dots (MQDs) with porous Cu nanosheets to design a novel heterostructured MQDs/Cu as effective and durable catalyst. Impressively, showed synergistica...

The aim of the study was to evaluate the effect of the addition of 20% bull seminal plasma to semen extenders on post-thaw sperm motility, morphology, and fertility. Two Merino rams at 3-5 years of age, 43 ewes, and one Holstein bull were used. Fourteen ejaculates were collected by the use of an artificial vagina, twice a day, at 60 min interval. Six semen ejaculates were extended with Tris-egg...

In 1952, India became the first country in the World to launch a family planning programme aimed at reducing population growth. But since then, as one keen observer had aptly put it, it has been “a saga of great expectations and poor performance” (Srinivasan, 1998). The overly optimistic demographic goals that have been set in various planned documents and policy statements have been continuous...

The electrochemical nitrogen reduction reaction (NRR) using clean energy is considered a promising alternative to the conventional Haber–Bosch process; however, developing highly active electrocatalyst still great challenge. In this study, ten metal dimers anchored in defective boron nitride (BN) monolayer as double-atom catalysts (DACs) with reverse sandwich structures were screened for their ...

Utilizing natural resources wisely, reducing pollution, and taking other environmental factors into account are now critical to the prospects for long-term economic growth and, by extension, sustainable development. We investigate impact of total resource rents (NRR) on India’s GDP in this study. The data sample consists NRR from World Bank’s official website collected between 1993 2020. In stu...

The nitrogen reduction reaction (NRR) under ambient conditions is still challenging due to the inertness of N2. Herein, we report a series superior NRR catalysts identified by examining Ti2NO2 MXenes embedded with 28 different single-atom using first-principles calculations. stability this system was first verified formation energies, and it discovered that N2 can be effectively adsorbed synerg...

The multimetallic sulfur-framework catalytic site of biological nitrogenases allows the efficient conversion dinitrogen (N2) to ammonia (NH3) under ambient conditions. Inspired by nitrogenases, a bimetallic sulfide material (FeWSx@FeWO4) was synthesized as highly N2 reduction (NRR) catalyst sulfur substitution surface FeWO4 nanoparticles. Thus prepared FeWSx@FeWO4 catalysts exhibit relatively h...
