A high throughput synthesis method is established to produce ultrathin MOF nanosheets and nanosheet membranes within only 30 min, shedding light on 2D high-performance membrane customization for separation and purification requirements.

This study initiatively developed the phosphor-free LED lamp based on high-efficiency yellow LED, and explored the photo-biological effects of yellow-green spectrum. Analyzing multiple ocular physiological parameters, cortical functional connectivity, and melatonin secretions at various moments, the authors demonstrated the positive photo-biological effects of yellow-green-rich phosphor-free LED lamp. This study revealed the spectral regulation mechanism and the intrinsic mathematic model of human physiological response, applicable in the fields of health-oriented lighting and displays.

UCLA and Broadcom researchers introduced the design and fabrication of a broadband, polarization-insensitive unidirectional imager operating in the visible spectrum. This device was fabricated through wafer-scale lithography on high-purity fused silica, offering high optical transparency, thermal stability and ultra-low loss. This work marks the first wafer-scale multilayer diffractive processor designed for visible imaging, enabling scalable, high-throughput production for advanced applications such as intelligent imaging, optical sensing, privacy protection, and all-optical information processing.

A research team led by Professor Sung Hoon Kim from the School of Electrical and Computer Engineering at Korea University has developed the world’s first alginate-based microrobot that can be tracked using Magnetic Particle Imaging (MPI). The newly developed system marks a major milestone in microrobotics by enabling real-time localization, selective thermal therapy, and cell delivery—all powered and controlled through a single magnetic actuation system, completely independent of conventional medical imaging devices such as cameras, CT, or X-ray machines.

Animals like bats, whales and insects have long used acoustic signals for communication and navigation. Now, an international team of scientists have taken a page from nature's playbook to model micro-sized robots that use sound waves to coordinate into large swarms that exhibit intelligent-like behavior. The robot groups could one day carry out complex tasks like exploring disaster zones, cleaning up pollution, or performing medical treatments from inside the body, according to team lead Igor Aronson, Huck Chair Professor of Biomedical Engineering, Chemistry, and Mathematics at Penn State.

New research by University at Buffalo and University of Colorado Boulder researchers has uncovered and characterized novel two-dimensional wave patterns — waves that propagate along two directions — whether they are in water or other settings like plasmas and condensed matter.
