Quantum-chemical calculations and electromagnetic simulations used to explain delocalization, state mixing and field enhancement.
Mark Martirez, a staff research scientist at the Princeton Plasma Physics Laboratory, simulates diamond qubit defects as isolated clusters of 16 to 30 atoms. Simulation turned up boron- and oxygen-based defects that could make useful qubits. They are candidates until someone grows and measures them.

Hessian Interatomic Potentials predict molecular Hessians directly and run one to two orders of magnitude faster, their authors report. A cheaper Hessian would make second-order chemistry workflows easier to run routinely, if the reported gains survive independent tests.

Surrey simulations predict a lithium-6 versus lithium-7 difference in a flavin-vitamin C radical reaction similar in size to one derived from animal studies. That makes nuclear spin a testable explanation for why the isotopes act differently in animals, though no experiment has checked it yet.

Magnetite nanoparticles formed in dye-laden water took up more than 90% of two dyes as they crystallised, and the same loaded particles later captured almost 80% of a third dye in a single-dye test reported in RSC Advances.

Researchers led by Cardiff University say the inductive effect stops at the first bond of a neutral molecule, and two A-level exam boards are already reviewing how they teach it. Their evidence is drawn largely from measurements that were already published.

A Science Tokyo team reports singlet exciton transport more than an order of magnitude past the 5-20 nm norm for organic semiconductors. The plasmonic bonus depends on how the fibers are laid down.
