Chemical organization in reaction-diffusion systems offer a strategy to generate materials with ordered morphologies and architecture. Periodic structures can be formed using molecules or nanoparticles. An emerging frontier in materials science aims to combine nanoparticles and molecules. In a new report on Science Advances, Amanda J. Ackroyd and a team of scientists in chemistry, physics and nanomaterials in Canada, Hungary and the U.S. noted how solvent evaporation from a suspension of cellulose nanocrystals (CNCs) and L-(+)-tartaric acid [abbreviated L-(+)-TA] caused the phase separation of precipitation to result in the rhythmic alteration of CNC-rich, L-(+)-TA rings. The CNC-rich regions maintained a cholesteric structure, while the L-(+)-TA-rich bands formed via radially elongated bundles to expand the knowledge of self-organizing reaction-diffusion systems and offer a strategy to design self-organizing materials.

Chemical organization

The process of self-organization and self-assembly occurs universally in non-equilibrium systems of living matter, geochemical environments, materials science and in industry. Existing experiments that lead to can be divided into two groups including the classical Liesegang-type experiments and chemical organization via periodic precipitation to generate materials with ordered morphologies and structural hierarchy. In this work, Ackroyd et al. developed a strategy for solvent evaporation to phase separate an aqueous solution of tartaric acid/cellulose nanocrystals [L-(+)-TA/CNC or TA/CNC] for its subsequent precipitation to result in a rhythmic alternation of CNC-rich or CNC-depleted ring-type regions. The team developed a kinetic model which agreed with the quantitatively. The work expands the range of self-organizing reaction-diffusion systems to pave the way for periodically structured functional materials.

Circa 2016

Clothing of the future could have the ability to repair itself after a tear – all you need to do is add water.

Researchers have developed a coating for textiles that can heal itself, and neutralize harmful chemicals.

They say this could one day be used to make chemically protective suits, helping to keep everyone from soldiers to farmers safe from toxic materials.

Breakthrough in quantum chemistry has implications for quantum technology.

Quantum technology has a lot of promise, but several research barriers need to be overcome before it can be widely used. A team of US researchers has advanced the field another step, by bringing multiple molecules into a single quantum state at the same time.

A Bose-Einstein condensate is a state of matter that only occurs at very low temperatures – close to absolute zero. At this temperature, multiple particles can clump together and behave as though they were a single atom – something that could be useful in quantum technology. But while scientists have been able to get single atoms into this state for decades, they hadn’t yet achieved it with molecules.

“Atoms are simple spherical objects, whereas molecules can vibrate, rotate, carry small magnets,” says Cheng Chin, a professor of physics at the University of Chicago, US. “Because molecules can do so many different things, it makes them more useful, and at the same time much harder to control.”

Getting closer.

Drugs and vaccines circulate through the vascular system reacting according to their chemical and structural nature. In some cases, they are intended to diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the side effects it causes —are a function of how well it can reach its target.

“A lot of medicines involve intravenous injections of drug carriers,” said Ying Li, an assistant professor of mechanical engineering at the University of Connecticut. “We want them to be able to circulate and find the right place at the right time and to release the right amount of drugs to safely protect us. If you make mistakes, there can be terrible side effects.”

Li studies nanomedicines and how they can be designed to work more efficiently. Nanomedicine involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for diagnosis, delivery, sensing or actuation purposes in a living organism. His work harnesses the power of supercomputers to simulate the dynamics of nanodrugs in the , design new forms of nanoparticles, and find ways to control them.

Researchers have developed a brain-like computing device that is capable of learning by association.

Similar to how famed physiologist Ivan Pavlov conditioned dogs to associate a bell with food, researchers at Northwestern University and the University of Hong Kong successfully conditioned their circuit to associate light with pressure.

The research will be published today (April 30, 2021) in the journal Nature Communications.

Still calling 2025 for the debut of a robotic set of human level hands.

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects – particularly in wet environments. Researchers have now discovered a new law of physics that accounts for this type of friction, which should advance a wide range of robotic technologies.

“Our work here opens the door to creating more reliable and functional haptic and robotic devices in applications such as telesurgery and manufacturing,” says Lilian Hsiao, an assistant professor of chemical and biomolecular engineering at North Carolina State University and corresponding author of a paper on the work.

At issue is something called elastohydrodynamic lubrication (EHL) friction, which is the friction that occurs when two solid surfaces come into contact with a thin layer of fluid between them. This would include the friction that occurs when you rub your fingertips together, with the fluid being the thin layer of naturally occurring oil on your skin. But it could also apply to a robotic claw lifting an object that has been coated with oil, or to a surgical device that is being used inside the human body.

Novel bio-sensing technologies to reduce food waste and optimize supply chains — a US$1 trillion need — katherine sizov — founder, strella biotechnology.

An estimated 40% of all global produce is wasted due to spoilage that occurs before it ever reaches consumers’ grocery bags. And this loss, not only represents loss due to quality or ripeness standards that consumers desire, but also a significant impact on global emissions and fresh water supplies that it took to produce and transport that produce, representing a combined figure of US$1 Trillion annually.

Katherine Sizov is the Founder of Strella Biotechnology (https://www.strellabiotech.com/), a company that builds novel bio-sensing platforms that can predict the ripeness of fruit and ultimately use this information to optimize supply chains by reducing food waste and increasing produce margins.

Strella won the 2019 President’s Innovation Prize (PIP) award from University of Pennsylvania, the grand prize at the Arizona State University Innovation Open, and the Venture Award at O3 World’s 1682 conference, and is recently is coming off of a US$3.3 million seed round with some very prominent institutional investors, including Marc Cuban Companies, Yamaha Motor Ventures & Laboratory Silicon Valley, and Catapult Ventures.

Katherine studied Molecular Biology and Chemistry, as well as Engineering Entrepreneurship, at the University of Pennsylvania.

A federal appeals court on Thursday said the Environmental Protection Agency (EPA) must ban a pesticide linked to developmental issues in children within 60 days unless it can find a safe use for the chemical.

The 9th Circuit ruled that the evidence compiled by the EPA fails to show that the substance chlorpyrifos is not harmful. Studies have linked exposure to chlorpyrifos to lower IQ, impaired working memory and negative impacts on motor development.

“The EPA has spent more than a decade assembling a record of chlorpyrifos’s ill effects and has repeatedly determined, based on that record, that it cannot conclude, to the statutorily required standard of reasonable certainty, that the present tolerances are causing no harm,” wrote Judge Jed Rakoff, a Clinton appointee, in the majority opinion. He was joined by Judge Jacqueline Nguyen, an Obama appointee.
