NMR Reveals Thermal Self-Organization in Resistive Switching of Organic Conductor by Japanese Team

NMR Reveals Thermal Self-Organization in Resistive Switching of Organic Conductor by Japanese Team

A joint research team from Tokyo University of Science, the National Institute for Materials Science, and RIKEN in Japan recently used bulk-sensitive ¹H-NMR measurements to reveal the internal electronic state of the organic conductor (d7-DMe-DCNQI)2Cu during resistive switching. The study found that, in the switching state, the material does not form a uniform new electronic phase, but rather a coexistence of metallic and insulating phases within the material. Schematic of bulk-crystal ¹H-NMR measurements Resistive switching refers to the phenomenon in which a material's resistance changes significantly under an applied current or voltage, and has attracted attention in research on correlated electron systems, memory devices, and neuromorphic devices.

U.S. Heavy-Ion Collision Research Suggests Protons and Neutrons May Not Be Just "Three Quarks"

U.S. Heavy-Ion Collision Research Suggests Protons and Neutrons May Not Be Just "Three Quarks"

The STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy's Brookhaven National Laboratory recently proposed, based on heavy-ion collision data studies, that baryons such as protons and neutrons may not be simply composed of three valence quarks, and that their baryon number may be more closely related to "baryon junctions" in the gluon field. The findings were published in the journal *Science*. In the traditional valence quark model, each quark is assigned a baryon number of 1/3, so baryons such as protons and neutrons, composed of three quarks, carry a baryon number of +1. However, this model is not a fundamental requirement of quantum chromodynamics (QCD). As early as the 1970s, alternative explanations had been proposed in the theoretical community; in 1996, Dmitri Kharzeev proposed a model suggesting that the baryon number is not necessarily carried by the quarks themselves, but may instead be concentrated at the Y-shaped junction formed by the gluon field—the "baryon junction."

Gallium ion FIB-SEM sample preparation has a damage limit; low-energy argon ion beam cleaning is used to improve TEM sample quality

Gallium ion FIB-SEM sample preparation has a damage limit; low-energy argon ion beam cleaning is used to improve TEM sample quality

Gallium ion focused ion beam-scanning electron microscopy (Ga⁺ FIB-SEM) has become an important method for site-specific thin lamella sample preparation for transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM), enabling cutting, extraction, and thinning of target regions at the nanometer scale. However, the literature indicates that while gallium ions provide high-precision machining capability, they also cause amorphization, ion implantation, and localized chemical modification on the sample surface, which can subsequently affect high-resolution imaging and energy dispersive spectroscopy analysis results. According to the literature, Ga⁺ FIB-SEM typically enables high-resolution site-specific machining at 30 keV, but high-energy gallium ions form a damage layer on the sample sidewalls. Taking silicon as an example...

Portable X-ray Equipment in the U.S. Used for On-Site Assessment of American Football Injuries

Portable X-ray Equipment in the U.S. Used for On-Site Assessment of American Football Injuries

As the 2026–2027 American football season approaches, team training camps, player evaluations, and medical support preparations are getting underway. Given the risk of acute sports injuries from the high-intensity physical contact in American football, portable X-ray equipment is being used to improve the efficiency of injury assessment on the sidelines and at training facilities. According to reports, American football players are prone to fractures, sprains, joint dislocations, and contusions. Relevant data indicates that the incidence of severe injuries such as fractures, dislocations, and contusions in this sport is higher than in other sports, with fractures accounting for approximately 10% of all football injuries. Such injuries typically require X-ray radiography to aid diagnosis, but traditional X-ray machines are bulky and fixed in place, usually requiring use in facilities with appropriate shielding. Injured players often need to be transported to the radiology department for examinations, which may delay diagnosis and treatment decisions.
