Single-atom vibrational spectroscopy now sensitive at the level of chemical bonds

Posted by in categories: chemistry, particle physics

Researchers led by Prof. Zhou Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom vibrational spectroscopy to the chemical-bonding-configuration extreme, which is critical for understanding the correlation of lattice vibrational properties with local atomic configurations in materials.

Using a combination of experimental and theoretical approaches, the researchers demonstrated the effect of chemical-bonding configurations and the atomic mass of impurity atoms on local vibrational properties at the single-atom level.

The study was published in Nature Materials.

‘Inkable’ nanomaterial promises big benefits for bendable electronics

Posted by in categories: chemistry, computing, mobile phones, nanotechnology

An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.

The material, , could be incorporated into many components of future technologies including mobile phones and computers, thanks to its versatility and recent advances in nanotechnology, according to the team.

RMIT University’s Associate Professor Enrico Della Gaspera and Dr. Joel van Embden led a team of global experts to review production strategies, capabilities and potential applications of zinc oxide nanocrystals in the journal Chemical Reviews.

Growing Neurons to Heal Brain Damage

Posted by in categories: chemistry, neuroscience

Watch as primordial neural cells dance across, grow into, and even move 3D scaffolds engineered to heal brain injury from stroke and other trauma. Decorating the scaffold with various nutrients and biochemical signals allow researchers to control what types of brain tissues they become.

Artificial neurons may repair damaged cells and circuits

Posted by in categories: biotech/medical, chemistry, robotics/AI

Electronic neurons made from silicon mimic brain cells and could be used to treat autism1.

Researchers plan to use the technology in conjunction with machine learning to retrain damaged or atypical neurons and restore function in the brains of people with Alzheimer’s disease, autism or other conditions.

Another team attempted to make artificial neurons in 2015 from a conductive organic chemical, but that version oversimplified brain signaling and was too large to implant in a human brain2.

Protecting Infrastructure

Posted by in categories: chemistry, economics, life extension

Year 2022 Basically this mechanoluminescence material can bring illumination to the mysterious info of stress in infrastructure so there could eventually be an easier way to measure aging infrastructure.


Both in Japan and other developed countries, social infrastructure built during periods of rapid economic growth is rapidly aging, and accidents involving aging infrastructure are becoming more frequent. The useful life of infrastructure is considered to be about 50 years due to the deterioration of concrete, a key component. Concrete eventually cracks due to internal chemical reactions and external forces, and so-called “moving cracks” that are gradually progressing due to the constant application of force are particularly dangerous. However, finding such cracks is a difficult task that requires significant time and effort. That’s why Nao Terasaki, a team leader at the National Institute of Advanced Industrial Science and Technology (AIST), and his colleagues have developed a luminescent material that helps reveal dangerous cracks by making them glow.

Electroactive bacterium generates well-defined nanosized metal catalysts with remarkable water-splitting performance

Posted by in categories: biological, chemistry, nanotechnology, particle physics, sustainability

A biological method that produces metal nanoclusters using the electroactive bacterium Geobacter sulfurreducens could provide a cheap and sustainable solution to high-performance catalyst synthesis for various applications such as water splitting.

Metal nanoclusters contain fewer than one hundred atoms and are much smaller than nanoparticles. They have unique electronic properties but also feature numerous active sites available for catalysis on their surface. There are several synthetic methods for making nanoclusters, but most require multiple steps involving and harsh temperature and pressure conditions.

DNA synthesis technologies to close the gene writing gap Reviews Chemistry

Posted by in categories: biotech/medical, chemistry

There is increasing demand for synthetic DNA. However, our ability to make, or write, DNA lags behind our ability to sequence, or read, it. This Review discusses commercialized DNA synthesis technologies in the pursuit of closing the DNA writing gap.

A Trendy New Chemical Theory for Where the Aliens Are Hiding

Posted by in categories: alien life, chemistry

There’s a theory that’s in vogue in astrochemistry called “Assembly Theory.” It posits that highly complex molecules—many acids, for example—could only come from living beings. The molecules are either part of living beings, or they’re things that intelligent living beings manufacture.

If Assembly Theory holds up, we could use it to search for aliens—by scanning distant planets and moons for complex molecules that should be evidence of living beings. That’s the latest idea from Assembly Theory’s originator, University of Glasgow chemist Leroy Cronin. “This is a radical new approach,” Cronin told The Daily Beast.

But not every expert agrees it would work—at least not anytime soon. To take chemical readings of faraway planets, scientists rely on spectroscopy. This is the process of interpreting a planet’s color palette to assess the possible mix of molecules in its atmosphere, land, and oceans.
