1-(5,7-Dihydroxy-2,2-dimethylchroman-6-yl)ethanone
In the title molecule, C13H16O4, the pyran ring is in a half-chair conformation. There is an intramolecular hydrogen bond involving the ketone O atom and an H atom of a phenol group which forms an S(6) ring.

Is Schr\"{o}dinger's Conjecture for the Hydrogen Atom Coherent States Attainable
We construct the most general SO(4,2) hydrogen atom coherent states which are the counterpart of Schr\"{o}dinger's harmonic oscillator coherent states. We show that these states cannot be localized and cannot follow the classical orbits.

Earthing effects on mitochondrial function: ATP production and ROS generation
In contrast to sham and naive controls, grounded mitochondria not only exhibit significantly enhanced energy production but also demonstrate a remarkable reduction in membrane potential and oxidative stress. This suggests a profound improvement in mitochondrial health, presenting a promising avenue for therapeutic interventions.

6-[(5-tert-Butyl-2-hydroxyanilino)methylene]cyclohexa-2,4-dienone
In the title compound, C17H19NO2, the dihedral angle between the two aromatic rings is 26.02 (5)°. One phenol O atom is deprotonated and the N atom of the azomethine unit carries the H atom, forming an intramolecular hydrogen bond. The packing

Noncommutative Coulombic Monopole
We have constructed the appropriate Hamiltonian of the noncommutative coulombic monopole (i.e. the noncommutative hydrogen atom with a monopole). The energy levels of this system have been calculated, discussed and compared with the noncommutative ...

Interaction of class III cellobiose dehydrogenase with lytic polysaccharide monooxygenase
The activity of lytic polysaccharide monooxygenase (LPMO) is supported by its auxiliary enzyme cellobiose dehydrogenase (CDH). The catalytic activity of both enzymes is coupled by electron transfer and a cyclic cascade generating substrates for both enzymes – hydrogen peroxide for LPMO and oxidized and non‐oxidized cellobiose and cello‐oligosaccharide ...

N′-(5-Bromo-2-hydroxybenzylidene)-3,4,5-trihydroxybenzohydrazide dihydrate
The title compound, C14H11BrN2O5·2H2O, crystallizes as hydrogen-bonded sheets. The 2-hydroxy group on the benzylidene group forms an intramolecular hydrogen bond to the N atom of the C=N double bond.

Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.

Study on synergistic effects of H and He in α-Fe
The synergistic effect of hydrogen and helium in α-Fe has been investigated using density functional theory calculation method. In perfect crystal of Fe, the presence of helium atom would decrease the dissolution energy of hydrogen atom near helium atom.

A critical analysis of the hydrino model
Recently, spectroscopic and calorimetric observations of hydrogen plasmas and chemical reactions with them have been interpreted as evidence for the existence of electronic states of the hydrogen atom with a binding energy of more than 13.6 eV.
