ABSTRACT: Geomagnetic storms are generally the main source of interplanetary and geomagnetic disturbances, constituting a major natural hazard due to their potential to damage technological and ...

After several decades, researchers are finally getting a grasp on when an odd and destructive type of oxygen arises in chemical reactions in living cells and certain batteries. Not all oxygen ...

Although Adriamycin (doxorubicin) and related anthracycline antitumor drugs are amongst the most important antitumor drugs in clinical use, their mode of biological activity is not completely ...

A new model of the active site of a key enzyme in cellular respiration allows scientists to study the enzyme under conditions where the flow of electrons is the limiting step, as it is in the natural ...

Combining theory and experiment, researchers have solved a long-standing problem by confirming the effects of -electron delocalization on 1,3-butadiene bond lengths. Organic chemistry texts use ...

What Are Quantum Numbers: Well, in the world of atoms, tiny particles whizz around a central nucleus. These particles are electrons and, unlike planets orbiting the sun in neat circles, electrons ...

Abstract: An outline of electron spin-relaxation is briefly presented with mechanisms and processes of spin-lattice relaxation in ionic and amorphous solids. Electron spin resonance (EPR) and pulsed ...

A team of scientists is proposing a new explanation for some cases of long Covid, based on their findings that serotonin levels were lower in people with the complex condition. In their study, ...
