Realization of quantum cascade laser operating at room temperature
, 2003 X-ray diffraction, as an effective probe and simple method, is used to ascertain the precise control of the epilayer thickness and composition. Intersubband absorption from the whole structure of the QC laser is used to monitor the wavelength of the QC ...

Advanced Energy Materials, EarlyView.Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

A Cholesterol Analogue for Cell‐Surface Enzyme Display
Angewandte Chemie, EarlyView.We report a non‐genetic strategy for bacterial cell surface enzyme immobilisation using cholesterol‐based artificial lipids containing Ni2+‐NTA binding groups that can integrate into biological membranes. The engineered cells can capture His‐tagged enzymes directly from cell lysates while preserving intracellular and surface activity, allowing for ...

Advanced Energy Materials, EarlyView.Metal‐halide perovskite solar cells offer high‐efficiency power for orbital missions but suffer from permanent proton‐induced degradation. This work identifies non‐ionizing energy loss (NIEL) as the primary driver of irreversible failure, inducing atomic displacements and microcracks in the high‐fluence regime. Through energy‐tuned mapping and scalable
