A way to electrically modify the chirality of organic–inorganic hybrid materials, in which chiral molecules adsorb onto inorganic surfaces, has been demonstrated by researchers at Science Tokyo. By using an electric double-layer transistor with a chiral electrolyte, specific chirality was imposed on an otherwise achiral molybdenum disulfide surface. This reversible method enables tunable chiral electronic states and opens new possibilities for advanced spintronic devices and the emerging field of “chiral iontronics.”

There is an increasing demand for novel materials with high-temperature oxidation resistance in harsh environments. Now, a joint research team from Jeonbuk National University and Korea Institute of Materials Science have demonstrated promising alumina-forming ferritic alloys that exhibit high-temperature oxidation resistance even under prolonged steam exposure. They achieve an outstanding balance between steam oxidation resistance, high-temperature strength, and cost- effectiveness, making them lucrative for high-temperature structural applications in extreme environments.

A research team from Peking University has successfully developed a vanadium oxide (VO₂)-based “locally active memristive oscillator” that operates at the edge of chaos. Through simple signal injection, the device exhibits diverse nonlinear dynamic behaviors such as frequency division, stochastic oscillation, and frequency locking. Remarkably, a single device demonstrates powerful frequency-domain feature extraction capability in speech recognition tasks, achieving performance comparable to a two-layer convolutional neural network. This breakthrough opens a new pathway for future energy-efficient and intelligent neuromorphic computing chips.

 In this system, Fc could convert overexpressed H₂O₂ to produce ·OH. Importantly, Cur could form dynamic boronate ester bonds with BA, and be encapsulated in SPSAs-1 through responsive chemical bond to form SPSAs-2. The acidic microenvironment and excessive H₂O₂ within tumor cells cause the dissociation of boronate ester bonds and β-CD/Fc complexes, releasing Cur. As a result, the GSH level could be reduced through the combination of the BA-induced GSH consumption and Cur-induced inhibition of TrxR activation, further enhancing CDT efficacy.

Structural alignment in fibrous tissues like myocardium and tendons is a key biomarker of physiological integrity and pathological remodeling. However, conventional imaging relies on staining. Researchers in Korea developed mid-infrared dichroism-sensitive photoacoustic microscopy, a label-free imaging modality that integrates molecular specificity with polarization sensitivity. It quantitatively maps protein content and extracellular matrix alignment in engineered heart tissues, enabling objective assessment of structural integrity and fibrosis without staining. This technique advances histopathology and regenerative medicine.
