Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

RESPONSE OF CsI:Pb SCINTILLATOR CRYSTAL TO NEUTRON RADIATION
The helium-3 world crisis requires a development of new methods of neutron detection to replace commonly used 3He proportional counters. In the past decades, great effort was made to developed efficient and fast scintillators to detect radiation.

By adjusting Ga's doping in Cu–Sn alloy, an ultra‐high elongation of 100.8% is achieved in first time. Ga forms a stable solid solution structure and a stronger electron exchange with Cu. This enhances strength‐ductility synergistically by tuning SFE to balance twinning and slip.

Halide perovskites in wide‐spectrum photodetection
Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...

The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed
