Study reports melting curve of superionic ammonia under icy planetary interior conditions
Icy planets, such as Uranus (U) and Neptune (N), are found in both our solar system and other solar systems across the universe. Nonetheless, these planets, characterized by a thick atmosphere and a mantle made of volatile materials (e.g., hydrogen w.....»»
Laser differential confocal Raman-Brillouin spectrum microscopy for analysis of cancer cells
There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor tissues can provide multi-dimensional information fo.....»»
Laser pulse creates exotic order in quantum material
Water flows, ice is rigid—this clear difference between the liquid and solid state of substances is part of our everyday experience. It follows from the very regular arrangement of atoms and molecules in crystalline solids, which is lost when they.....»»
Impact of film thickness in laser-induced periodic structures on amorphous Si films
Since the scientists at Bell Labs invented the world's first transistor in December 1947, a revolution in microelectronics technology has profoundly affected lifestyles worldwide. As electronics get smaller and smaller, it is a challenge to find an e.....»»
Tracking ships" icy paths amidst climate change
There has been much buzz about the warming planet's melting Arctic region opening shipping routes and lengthening travel seasons in ocean passageways that ice once blocked. Expanded fishing, trade and tourism is envisioned. The operative word here is.....»»
Fossilized beaches help scientists understand impacts of past global warming
Fossilized beaches along the UK coastline have enabled scientists to demonstrate for the first time how melting Antarctic ice sheets impacted global sea levels during a period of pronounced climate warming more than 100,000 years ago......»»
Nvidia may have finally fixed its melting power connectors
Nvidia's controversial 12VHPWR connector managed to wreak some havoc in people's PCs, but it seems that Nvidia is changing things up......»»
