Holographic optical elements (HOEs) are essential in augmented reality (AR) displays, providing benefits such as design flexibility and improved optical efficiency. However, current materials' limited refractive index modulation hampers performance, part

Chronic diabetic wounds are prevalent in patients and are difficult to heal, presenting a significant medical challenge. The development of multifunctional hydrogel dressings with a well-designed morphology and structure can enhance their flexibility and

As far as water gear goes, floaties are not exactly high tech. But the tiny air-filled bubbles some microorganisms use as flotation devices when they compete for light on the water surface are a different story.

The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the atomic level manufacturing of semiconductors. The basic idea of atomic level manufacturing is to process and manipulate matt

Single-walled carbon nanotubes (SWCNTs) are known for their remarkable properties, which make them essential in many advanced technologies. Yet, creating these nanotubes efficiently and on a large scale has been a persistent challenge.

Researchers have fabricated a quasi-one-dimensional van der Waals zirconium telluride thin film, which is a form of a substance that has long promised advances in quantum computing, nano-electronics and other advanced technologies. Until now, it has stump

Micro- and nanoplastics are in our food, water and the air we breathe. They are showing up in our bodies, from testicles to brain matter. Now, University of British Columbia researchers have developed a low-cost, portable tool to accurately measure plasti

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, used high-speed atomic force microscopy to observe dynamic changes in AMPA receptors, which are vital for brain communication. Their findings, published in ACS Nano, reveal

An international group of researchers has developed a novel approach that enhances the efficiency of the oxygen evolution reaction (OER), a key process in renewable energy technologies. By introducing rare earth single atoms into manganese oxide (MnO2), t

A researcher in Purdue University's College of Science is developing a patent-pending platform technology that mimics the dual-layer structure of viruses to deliver nucleic acid (NA)-based therapies to targeted cancer cells.

Chloroplast, which is a double-membrane-bounded organelle, is the main site for CO2 fixation via photosynthesis in green plants. The double-membrane configuration can regulate the transport of substances into and out of the chloroplasts with the aid of fu

It is well known that more and more plastic waste is ending up in soil and bodies of water. Researchers are particularly concerned about tiny micro- and nano-sized particles. It remains unclear how and to what extent they are able to enter living organism
