Convection in vertical Bridgman configurations [PDF]

, 1991
We are interested in tracing the convective profiles of vertical Bridgman growth in two configurations, the pure Rayleigh convective mode and the combined Rayleigh-Marangoni mode.

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Neutron Diffraction Evidence for Stress‐Induced Melting of Ice During Deformation of D2O‐Ice Ih—Fluorite Mixtures

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Water ice is an important rock‐forming mineral, both on the Earth and on various extraterrestrial bodies. Naturally occurring ice is often “dirty”–an intimate mixture with harder mineral grains, which can have significant effects on the bulk properties of the aggregate. We have used neutron powder diffraction, with in situ triaxial deformation,

From Materials to Medical Images: Translating Perovskite‐Based X‐Ray Detectors Toward Clinical Imaging

Advanced Science, Volume 13, Issue 40, 17 July 2026.
This review examines perovskite‐based X‐ray detectors from a materials‐to‐medical‐images perspective. Recent progress in perovskite‐based X‐ray detectors is discussed with emphasis on their relevance to clinical imaging. The key barriers to clinical implementation are analyzed.

RESPONSE OF CsI:Pb SCINTILLATOR CRYSTAL TO NEUTRON RADIATION

EPJ Web of Conferences, 2018
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.

An induction heating system for in situ X‐ray diffraction imaging: design, simulation and application to dislocation dynamics in semiconductors

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 1126-1142, July 2026.
This work presents a compact induction heating system for time‐resolved in situ X‐ray diffraction imaging. The system enables contact‐free volumetric heating up to approximately 1600°C and provides flexible operation in different operating modes. Its performance is demonstrated through representative diffraction imaging experiments.We present a compact

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.
