Professor Do Hyun Ryu's research team in the Department of Chemistry at Sungkyunkwan University (SKKU) has developed two new asymmetric catalytic methods for the precise synthesis of complex molecules using chiral organic catalysts. The team demonstrated that a single catalyst can promote two different carbon-carbon bond-forming reactions with high selectivity.
Dedicated carbon monoxide measurement complements Hiden mass spectrometry for syngas, biogas and catalysis applications.
A Defense Technology review examines how tunable plasma layers could absorb, reflect, refract, and scatter radar signals to reduce the radar cross-section of aircraft and other military platforms. The authors assess plasma-generation methods, hybrid stealth systems, and the substantial challenges in power, stability, communication, and integration that still separate laboratory research from operational use.
A review of durable superhydrophobic materials reframes surface design around three dominant failure modes: structural degradation, loss of low-surface-energy chemistry, and coating-substrate interfacial failure. The authors connect fabrication choices with failure-matched testing and examine fluorine-free chemistries, protected architectures, self-healing systems, and interface engineering as routes toward longer service life in demanding environments.
Researchers developed an AI-assisted computational pipeline that combines symmetry-guided screening, machine learning, and density functional theory to search for altermagnetic metal-organic frameworks. The approach also identified molecular features associated with altermagnetism and spin splitting, providing design rules for selecting future candidates for computational and experimental study.
Researchers reviewed advances in alloy-based anodes for rechargeable magnesium batteries, comparing Mg-free hosts, Mg-containing alloys and alloy-derived surface modifications as routes to improve reversibility, Mg²? transport and electrolyte compatibility. The review finds that material structure and interphase chemistry strongly influence performance, while higher alloy-anode operating potentials can reduce full-cell voltage, and practical validation remains a major research priority.
Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall off.
Electrochemical research often requires more than current, potential and time data alone. While a potentiostat provides essential control and measurement of the electrochemical experiment, it does not directly identify the gases or volatile species being produced during a reaction.
As transistors approach atomic dimensions, the interface between different materials grows in importance. Researchers from?National Yang Ming Chiao Tung University (NYCU), TSMC Corporate Research, and colleagues from National Taiwan University, Academia Sinica, and the National Center for Instrumentation Research have devised an interface engineering approach to address a major challenge in two-dimensional (2D) transistors.
Researchers developed a room-temperature, maskless electrodeposition method for directly 3D-printing freestanding copper microinductors onto chip contact pads, enabling inductance to be generated without requiring additional dedicated planar silicon area. The printed microsolenoids achieved nanohenry-range inductance, quality factors up to 18, and experimentally validated inductive behavior up to 15 GHz, supporting their potential for post-fabrication integration into future RF electronics.
