Using a STEM-in-SEM conversion holder, we can convert a scanning electron microscope into a scanning transmission microscope. Neat... ==== Timeline ==== 0:00 Intro 0:27 How an SEM works 1:50 ...

An international research team reports the discovery of "hidden order" in systems that are disordered in space and time. The paper is published in the journal Nature Materials. The results were ...

Worcester Polytechnic Institute (WPI) researchers have created a new carbon-negative building material that could transform sustainable construction. The breakthrough, published in the high-impact ...

(a) The schematic of the fabricated ZnO device. Two-dimensional electron gas is formed between (Mg, Zn)O and ZnO. Quantum dots are formed by applying gate voltage to this two-dimensional electron gas.

Unlike optical microscopy, SEM does not rely on light waves but instead uses a beam of electrons to interact with materials, enabling magnifications up to 300,000× and resolutions approaching 1 nm. 1 ...

Microplastics are tiny, plastic fragments — many too small to see — found in the air, soil and water. Measuring their abundance in nature can direct cleanup resources, but current detection methods ...

Since its discovery in 1999, the near-Earth asteroid Bennu has captivated scientists as a time capsule from the early solar system — and also as a key to possibly understanding the origins of life. To ...

NASA's James Webb Space Telescope has made its first observations of interstellar comet 3I/ATLAS, revealing that the comet appears to be unusually rich in carbon dioxide. When you purchase through ...

3D NAND flash memory is built by vertically stacking multiple alternating layers (tiers) of silicon nitride (SiN) and oxide (TEOS) on top of each other. A major challenge in producing multilayered 3D ...

Staph infections can be deadly, especially in hospitals where certain strains have evolved to be resistant to antibiotics. The bacteria responsible for these infections, Staphylococcus aureus, is ...

In a bold challenge to silicon s long-held dominance in electronics, Penn State researchers have built the world s first working CMOS computer entirely from atom-thin 2D materials. Using molybdenum ...
