Tailored Synthesis of Doped Non‐Layered Oxide Nanosheets Using Designed Solid‐State Surfactants
Advanced Science, EarlyView.This work reports a solid‐state surfactant templating method that enables precise doping of non‐layered oxide nanosheets. Using ceria and rare‐earth elements as model systems, we established design principles for solid‐state surfactants containing multiple elements.

Hydrogen‐State‐Engineered Oxide Semiconductor Channels Enabling Reliable 2T0C DRAM Operation
Advanced Electronic Materials, EarlyView.We introduce a three‐step hydrogen annealing method for oxide semiconductor devices that modulates hydrogen incorporation and its passivation behavior. Consequently, interface traps are suppressed, whereas the mobility, reliability, and data retention of the IGO‐based 2T0C DRAM are simultaneously improved.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, EarlyView.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...
