Huzhou, Zhejiang Launches Phase I "Drug-Device Combination" Clinical Trial for the Province's First BNCT System
Recently, the Boron Neutron Tumor Treatment Center at Huzhou Hospital Affiliated to Zhejiang University School of Medicine has drawn attention with the introduction of the province's first Boron Neutron Capture Therapy (BNCT) system. Previously, the system had already initiated a Phase I BNCT drug-device combination clinical trial. According to the system developer, Huapeng Neutron Technology (Hangzhou) Co., Ltd., BNCT is a radiotherapy technique combining drugs and devices, with its core lying in the coordinated use of boron-containing drugs and neutron irradiation. After entering the human body, the boron-containing drug can be absorbed by tumor cells; subsequent neutron beam irradiation triggers a localized reaction to achieve targeted radiotherapy against tumor cells. Unlike conventional radiotherapy, which typically employs fractionated irradiation over a longer treatment course, BNCT emphasizes selective targeting of tumor cells, aiming to reduce damage to surrounding healthy tissues and lower radiotherapy-related side effects such as hair loss and immunosuppression.

Korean Research Team Reveals Mechanism Behind Neutron Irradiation-Induced Reliability Degradation in Ferroelectric AI Semiconductors
Jeonbuk National University announced on the 20th that a research team led by Professor Bae Hak-yeol from the Department of Electronic Engineering at its College of Engineering, in collaboration with Professor Kim Tae-wan's team at Seoul National University and Q-Beam Solution, a startup affiliated with the Korea Atomic Energy Research Institute, conducted a joint study analyzing the causes of performance degradation in next-generation ferroelectric memory and neuromorphic semiconductor devices under neutron irradiation. The findings have been published in the latest issue of ACS Applied Electronic Materials. Ferroelectric semiconductors, which can maintain their polarization state even after power is disconnected, are considered a key candidate for next-generation non-volatile memory and neuromorphic computing devices. Neuromorphic computing aims to simultaneously implement both memory and computation within a single device...

CERN measures niobium-94 neutron capture for the first time, shedding new light on the mystery of molybdenum abundance in ancient stardust
The n_TOF collaboration at CERN recently reported that researchers have for the first time measured the probability of neutron capture by niobium-94. The results, published in Physical Review Letters, provide new experimental evidence for explaining the anomalous abundance of molybdenum-94 in presolar grains. The EAR2 facility in the n_TOF experiment at CERN produces intense neutron beams, opening new possibilities for nuclear research. Credit: CERN Niobium-94 is a niobium isotope containing 41 protons and 53 neutrons, occupying a critical juncture in the nuclear reaction chain that produces heavy elements in dying stars. Researchers are interested in it because niobium-94 is very close to molybdenum-94, differing by just one fewer proton and one more neutron. Under the high-temperature, high-pressure conditions inside stars, niobium-94 may either transform into molybdenum-94 through beta decay or form niobium-95 through neutron capture. The competition between these two reaction pathways directly affects scientists' understanding of the origin of molybdenum-94.

Russian enterprise develops borated polyethylene material for neutron radiation protection
A neutron radiation protection material developed by Russian company NPO Gelar has obtained relevant certification. The material, named Polikeramoplast-PB, is a borated polyethylene that resembles ordinary gray or black plastic sheets in appearance, but its protective performance derives from the combination of hydrogen and boron. According to reports, the hydrogen in the material effectively moderates fast neutrons, reducing the likelihood of subsequent secondary reactions, while the boron helps absorb moderated neutrons. In contrast, traditional heavy metal materials used for gamma-ray shielding are not suitable for standalone neutron protection, as heavy atomic nuclei have limited attenuation effects on neutrons. The material can be used in radiation therapy room protection systems and combined with lead...

Neutron and X-ray tomography reveal hydrogen-rich regions in Martian meteorite "Black Beauty"
An international team of researchers from Denmark, Sweden, and Switzerland recently conducted a three-dimensional non-destructive analysis of a slice of the Martian meteorite NWA 7034 "Black Beauty" using neutron tomography and X-ray tomography, discovering macroscopic hydrogen-rich regions within it. The study suggests that these hydrogen-rich features provide evidence of early water-rock interactions on Mars. The findings have been published in Geophysical Research Letters. Black Beauty is a brecciated meteorite from Mars that was ejected into space by an impact event and eventually landed in the Sahara Desert in Morocco. Weighing approximately 320 grams, the meteorite contains material up to 4.48 billion years old, making it one of the oldest known Martian crustal fragments...
