Syllabus: The NTA has put the official JEE Main 2026 Syllabus online on their website: jeemain.nta.nic.in. If you're planning ...

Here we present cryoelectron crystallographic analysis of an isolated dimeric oxygen-evolving complex of photosystem II (at a resolution of ~0.9 nm), revealing that the D1–D2 reaction center (RC ...

We report the preparation, crystallization, and solid-state characterization of the first two members of a new family of spiro-bis(1,9-disubstituted phenalenyl)boron neutral radicals based solely on ...

An effective Hamiltonian mixed molecular orbital and valence bond (EH-MOVB) method is described to obtain accurate potential energy surfaces for chemical reactions. Building upon previous results on ...

Letter Published: 18 October 1958 Uptake of Molecular Oxygen by Ferrous Complexes J. F. DRAKE & R. J. P. WILLIAMS Nature 182, 1084 (1958) Cite this article ...

A similar mixing will also occur between the iron 3d orbitals and the Ti orbitals via the intervening oxygen atoms. We have also recorded PA spectra of Fe/sub 2/O/sub 3/, ZnO, NiCO/sub 3/ and TiO/sub ...

In this oxygen-free environment, the spoilage bacteria don't multiply very fast, which helps maintain the quality of the food product. Some dangerous bacteria, like Clostridium botulinum that causes ...

Interaction of molecular oxygen with semiconducting oxide surfaces plays a key role in many technologies. The topic is difficult to approach both by experiment and in theory, mainly due to multiple ...

Adsorption of molecular oxygen with a triplet ground state on Fe -, Co -, Ni -, Ru -, Rh -, Pd -, OS -, Ir - and Pt -doped graphene is studied using density functional theory (DFT) calculations. The ...
