Multistep mechanism of nanostructure formation in liquid crystal
Most of our daily commodities, such as plastics, alloys and processed foods, are provided as solids, and they are often processed by a controlled cooling process from a liquid mixture to a solid. Liquid crystals, solutions, polymers, and biomaterials.....»»
Astronomers find direct link that supernovae give rise to black holes or neutron stars
Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the universe—black holes and neutron stars. With the help of the European Southern Observatory's Very.....»»
A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular me.....»»
Study uncovers low-temperature deformation mechanism of pure titanium
Titanium (Ti), often hailed as the wonder metal for its remarkable properties, has many applications in aerospace, marine, and biomedicine industries. Known for their low density, high strength, high ductility, great corrosion resistance, and excelle.....»»
New study suggests some forms of life could exist in Venus"s sulfuric acid clouds
A team of chemists and planetary scientists from Worcester Polytechnic Institute, Nanoplanet Consulting and MIT has found evidence that a form of life that uses sulfuric acid as a liquid medium could exist in some of the clouds covering Venus. The te.....»»
Elucidating the process of bile duct formation in the liver
Bile ducts are pathways that carry hepatocyte-produced bile from the liver to the small intestine. In the human fetal liver, bile ducts are formed from bile duct epithelial cells surrounding the portal vein, and hepatocytes form on the outside. Both.....»»
Researchers discover how atmospheric feldspar dust contributes to cloud formation
Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role. Fine powder carried by air influences cloud formation. Water molecules adhere better to feldspar d.....»»
Researchers reveal new findings on diamond rain on ice planets
An international team of researchers led by Dr. Mungo Frost from the SLAC research center in California has gained new insights into the formation of diamond rain on icy planets such as Neptune and Uranus, using the X-ray laser European XFEL in Schen.....»»
Unraveling the mystery of lignosuberization: A comprehensive study of periderm formation in Sikkim cucumber fruit skin
In fleshy fruits, periderm tissue often forms on the skin surface as a response to mechanical damage caused following environmental cues or developmental programs, known as lignosuberization, creating a protective, corky matrix......»»
Tumor microenvironment-activated nanostructure enables precise multi-modal therapy
Recently, a research team led by Prof. Wu Zhengyan from Hefei Institutes of Physical Science, Chinese Academy of Sciences, in collaboration Binzhou Medical University, successfully designed a nanostructure that improves the detection and treatment of.....»»
Stripes in a flowing liquid crystal suggest a route to "chiral" fluids
Hold your hands out in front of you, and no matter how you rotate them, it's impossible to superimpose one over the other. Our hands are a perfect example of chirality—a geometric configuration by which an object cannot be superimposed onto its mir.....»»
Researchers discover important membrane transport mechanism in pathogenic bacteria
Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside t.....»»
Metal-organic frameworks study unravels mechanism for capturing water from air
Researchers from the Helmholtz-Zentrum Dresden-Rossendorf and Dresden University of Technology have unraveled the water adsorption mechanism in certain microporous materials—so-called hierarchical metal-organic frameworks (MOFs)—while probing the.....»»
Face to face with sun-eclipsing Proba-3
Through exquisite, millimeter-scale, formation flying, the dual satellites making up ESA's Proba-3 will accomplish what was previously a space mission impossible: Cast a precisely held shadow from one platform to the other, in the process blocking ou.....»»
New crystalline sponge method proposed for undergraduate courses
The crystal sponge technology is a revolutionary technique, which enables the direct and precise determination of the molecular structure of liquid and gas targets. The technique uses a special network complex to selectively absorb liquid or gas targ.....»»
The zaï technique: How farmers in the Sahel grow crops with little to no water
Hubert Reeves once wrote that "on the cosmic scale, liquid water is rarer than gold". And what is true for the universe is even truer in the Sahel, the name given to the vast, arid belt that skirts the Sahara and stretches across Africa from east to.....»»
A dense quark liquid is distinct from a dense nucleon liquid
Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quar.....»»
A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets, study finds
Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers' best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the presence, of a chemical feature in their atmospheres.....»»

This Samsung 75-inch 4K TV deal includes a discount on a Crystal UHD smart TV that you don't want to miss......»»
BarbNet: Awn phenotyping with advanced deep learning, potential applications in the automation of barley awns sorting
Awns, bristle-like extensions on grass crops like wheat and barley, are vital for protection and seed dispersal, with barbs on their surface playing a crucial role. While the genetic basis of barb formation has been explored through genome-wide assoc.....»»
Engineers pair laser light to crystal lattice vibrations to enhance optical properties of 2D material
Engineers at Columbia University and theoretical collaborators at the Max Planck for the Structure and Dynamics of Matter have found that pairing laser light to crystal lattice vibrations can enhance the nonlinear optical properties of a layered 2D m.....»»
