Scientists have discovered yet another amazing aspect of the weird and wonderful behavior of water—this time when subjected to nanoscale confinement at sub-zero temperatures.

The finding that a crystalline substance can readily give up water at temperatures as low as −70 °C, published in the journal Nature on April 12, has major implications for the development of materials designed to extract water from the atmosphere.

The protoplanet was found surrounding HD 169,142, a star located 374 light years from our solar system.

Astronomers have caught a rare glimpse of a planet’s formation. This is only the third time scientists have discovered a protoplanet — an early stage in forming a planet, where cosmic material clumps in a disk surrounding newborn stars.

The observation of new protoplanet.

A team led by Prof. Zeng Changgan and Associate Researcher Li Lin from the University of Science and Technology (USTC) / Chinese Academy of Sciences (CAS) Key Laboratory of Strongly-Coupled Quantum Matter Physics, collaborating with Prof. Feng Ji’s team from Peking University, revealed significant quantum interference effect in inter-layer transport process for the first time using graphene-based electronic double-layer systems. Their work was published in Nature Communications.

Coulomb drag is an effect that occurs between two conductive layers in proximity but insulated from each other, wherein moving carriers in one layer (active layer) induces the transport of carriers in the other layer (passive layer), thereby generating an open-circuit voltage in the passive layer.

Coulomb drag has been widely applied in previous studies of long-range interactions between carriers, such as the Bose-Einstein condensation of indirect excitons. However, there is a lack of research on the external field response and possible quantum effects of the Coulomb drag.

A new material was used in a simple snail robot, but it could one day make artificial nervous systems for more complex machines.

Nearly 200 years since its discovery, industry rarely uses the carbon–carbon bond-forming Kolbe reaction – but now US researchers have shown it can sustainably make valuable substances.

Phil Baran’s team at Scripps Research Institute in La Jolla has done away with high voltages and platinum electrodes best established in the Kolbe reaction. In doing so, the researchers have made it much more versatile. ‘The most important feature is the ability to take waste or similarly priced products convert them into extremely high value materials,’ Baran tells Chemistry World.

Scientists are still getting to grips with the ins and outs of strange materials known as time crystals; structures that buzz with movement for eternity. Now a new variety might help deepen our understanding of the perplexing state of matter.

Just as regular crystals are atoms and molecules that repeat over a volume of space, time crystals are collections of particles that tick-tock in patterns over a duration of time in ways that initially seem to defy science.

Theorized in 2012 before being observed in the lab for the first time just four years later, researchers have been busy tinkering with the structures to probe deeper foundations of particle physics and uncover potential applications.

The industry, particularly in the U.S. is undergoing significant growing pains with demand outstripping supply in materials and personnel.

An international team, headed by the University of Geneva (UNIGE), has created a quantum material that allows the fabric of the space inhabited by electrons to be curved on demand.

The advent of cutting-edge information and communication technologies presents scientists and industry with new hurdles to overcome. To address these challenges, designing new quantum materials, which derive their remarkable characteristics from the principles of quantum physics, is the most promising approach.

A global collaboration headed by the University of Geneva (UNIGE) and featuring researchers from the universities of Salerno, Utrecht, and Delft, has developed a material that allows for the control of electron dynamics by curving the fabric of space in which they evolve. This advancement holds promise for future electronic devices, particularly in the field of optoelectronics. The findings were published in the journal Nature Materials.

Origami robots are autonomous machines that are constructed by folding two-dimensional materials into complex, functional three-dimensional structures. These robots are highly versatile. They can be designed to perform a wide range of tasks, from manipulating small objects to navigating difficult terrain. Their compact size and flexibility allow them to move in ways that traditional robots cannot, making them ideal for use in environments that are hard to reach.

Another notable feature of origami-based robots is their low cost. Because they are constructed using simple materials and techniques, they can be produced relatively inexpensively. This makes them an attractive option for many researchers and companies looking to develop new robotics applications.

There are many potential applications for origami robots. They could be used in search and rescue missions, where their small size and flexibility would allow them to navigate through rubble and debris. They could also be used in manufacturing settings, where their ability to manipulate small objects could be put to use in assembly lines.
