Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Measuring thermal conductivity in extreme conditions: sub-Kelvin temperatures and high (27 T) magnetic fields

open access: yes, 2003
We present a one-heater-two-thermometer set-up for measuring thermal conductivity and electric resistivity of a bulk sample at low temperatures down to 0.1 K and in magnetic fields up to 27 Tesla.

Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

A comparison of temporal artery thermometers with internal blood monitors to measure body temperature during hemodialysis

open access: yesBMC Nephrology, 2018
Background Thermometers that measure core (internal) body temperature are the gold standard for monitoring temperature. Despite that most modern hemodialysis machines are equipped with an internal blood monitor that measures core body temperature ...

Control of Covalent Bond Enables Efficient Magnetic Cooling

open access: yesAdvanced Materials, EarlyView.
Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Single‐Cell Hyperthermia: Diamond Quantum Thermometry Reveals Thermal Control of Macrophage Polarization

open access: yesAdvanced Materials, EarlyView.
Photothermal nanodiamonds with quantum sensing capabilities generate lysosome‐confined hyperthermia, enabling simultaneous temperature and radical detection via diamond sensing. This localized thermal and oxidative stress drives pro‐inflammatory (M1) macrophage polarization, revealing a new strategy for precision immunomodulation through subcellular ...
