Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Smectic C Self‐Assembly in Mesogen‐Free Liquid Crystalline Chiral Polyethers with Sulfonylated Methyl‐Branched Side Chains

open access: yesMacromolecular Rapid Communications, Volume 44, Issue 1, January 2023., 2023
Smectic C self‐assembly is achieved for the first time in mesogen‐free liquid crystalline chiral polymers with sulfonylated methyl‐branched alkyl side chains, as revealed by X‐ray diffraction and polarized light microscopy. These polymers exhibit high dielectric constants between 7.9 and 11.7.
