Low temperatures and high water/rock ratios in asteroid (101955) Bennu's history based on X‐ray powder diffraction of returned samples

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1077-1094, June 2026.
Abstract Samples returned by NASA's OSIRIS‐REx mission from the carbonaceous asteroid (101955) Bennu hold clues about conditions in the early solar system and the formation of planetary bodies. Initial investigation of Bennu samples found that they are rich in phyllosilicates and other secondary minerals formed during aqueous alteration of a larger ...

Detection voltage PSD (distance PSD-VCSEL 40 cm) without collimation

, 2022
 The dataset contains the voltage measured  by a PSD (Position Sensing Detector) depending on the x-position of a  VCSEL light source (850 nm). The VCSEL is not collimated, and at a z-position of 40 cm of the PSD.

Synergistic Electron Density and Oxygen Defect Regulation in Fluorite High‐Entropy Oxides for Superior Ionizing Radiation Shielding

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...

Hybrid VLC–IR Communication System With Beam‐Steered Uplink and Turbo Coding Under Mobility

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
This paper presents a hybrid VLC–IR communication system integrating a beam‐steered infrared uplink with Turbo coding for reliable indoor optical wireless links. The proposed architecture achieves BER below 10−3 at 10 dB SNR and maintains stable coverage under NLOS conditions through adaptive beam steering.
