Glass Transition

To make glass from soft tissue the sequence of events must be exactly right. This is how we think it happened

An international team of researchers has succeeded in "filming" the activation of an important receptor. They froze the involved molecules at different points in time and photographed them under the electron microscope. They were then able to place these still images in sequence. This sequence shows step by step which spatial changes the receptor undergoes when it is activated.

A new MIT framework uses machine learning to simultaneously predict molecular properties and generate new molecules using only a small amount of data for training.

Most crystalline materials are polycrystals, such as metals. They are composed of many small crystalline grains with different lattice orientations. The interface between two crystalline grains, i.e., the grain boundary, is a thin layer of disordered particles about one or two particles thick.

The first of two 300-tonne melters at the Hanford Site in Washington State which will transform radioactive and chemical waste into a glass form for safe disposal will take several weeks to reach its commissioning and operational temperature of 2100°F (1149°C).

For decades people have arranged to freeze their bodies after death, dreaming of resurrection by advanced future medicine. Many met a fate far grislier than death.

Researchers used an Artificial Intelligence Materials Selection framework (AIMS) to discover a new shape memory alloy. The shape memory alloy showed the highest efficiency during operation achieved thus far for nickel-titanium-based materials. In addition, their data-driven framework offers proof of concept for future materials development.

A supercritical fluid is a highly-compressed fluid that combines the properties of gases and liquids. Supercritical fluids have a range of supporting technologies used in several industrial applications. They form the basis of clean technology as an alternative solvents for extracting natural products, chemicals and other substances. How do you create a Supercritical Fluid? Applying...

Since this is a 101, let's start with the basics. What is cryonics? Speaking from a consumer's point of view, I view cryonics as life insurance. Not the usual euphemism for a payout to one's loved…

Optical micro and nanofibers (MNFs) have extensive applications in nonlinearity generation, near-field optics, quantum optics, and miniaturized sensing. Although MNFs have fostered the development of various disciplines, there have been few studies on the topic until the convenient fabrication of low-loss MNFs was made possible.

The process of liquid-to-glass transition is a complex procedure in science, as is the glass-to-liquid transition known as glass melting. In a new report published in Science Advances, Qi Zhang and a research team in physics at the Hong Kong University of Science and Technology in China assembled colloidal glasses via vapor deposition and melted them to observe the glass transition dynamics.

Cold temperatures stiffen tire rubber and reduce their performance even on dry roads, which is why experts suggest getting winter tires in cold climates.

Glasses are peculiar materials exhibiting excellent and well-known properties, but also some phenomena that are still not fully understood, even though they have been studied for more than a century. In particular, researchers have not yet reached a complete description of the glass formation process, upon cooling a liquid, and the converse transition of glass to a more stable state—called supercooled liquid—when…

Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) have prepared a P-Sn-O-Cl-N glass system at 350 °C and explored its structural properties.

A big problem with the disposal of nuclear and electronic wastes is that the process wastes precious metals such as gold and platinum-group metals, which are key metals in computer chips. Researchers form Nagoya University in collaboration with those from the Tokyo Institute of Technology have discovered that a solution to this pressing environmental and technological problem may lie in a pigment named Prussian…

In an 'historic' first, scientists freeze, thaw, and transplant rat organs — bringing transplant medicine one step closer to sci-fi dreams of stopping biological time.

Chloroplasts' choreography keeps plant cells powered

In a study published in Advanced Materials, a research team led by Prof. Luo Xuan from Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences made a breakthrough in tuning electronic properties of Weyl semimetal Td-MoTe2 by intercalating 3d-element Fe atoms into the van der Waals (vdW) gap, which brought about exotic electronic behaviors as well as the first-time observed magnetic states in…

Comparison of model simulations with atmospheric observations from the Southern Hemisphere mid-latitudes following the 2020 Australian wildfires shows that the wildfire aerosol composition promotes stratospheric chlorine and ozone depletion chemistry.

Tardigrades are able to tolerate almost complete dehydration by entering a reversible state called anhydrobiosis and resuming their animation upon rehydration. A study of the stress-dependent condensing properties of tardigrade tolerance proteins reveals how they work to enhance the physical stability of cells and counteract environmental stress in an on-demand manner.
