A team of engineers led by the University of Massachusetts Amherst and including colleagues from the Massachusetts Institute of Technology (MIT) recently announced in Nature Communications that they had successfully built a tissue-like bioelectronic mesh system integrated with an array of atom-thin graphene sensors that can simultaneously measure both the electrical signal and the physical movement of cells in lab-grown human cardiac tissue.

For the past hundred years, it has been widely recognized through X-ray and electron diffraction measurements that graphene interlayers can only accommodate a single layer of alkali metal. Each layer being fully filled by single layer alkali metal atoms is considered the theoretical charging limit.

However, there have been no reports of studies directly observing the atomic arrangement of interlayer alkali metals and verifying whether graphene layers can only accommodate a single layer of alkali metal atoms or whether other techniques can achieve higher density or multiple layers of alkali metals.

The research team developed a technique to insert dense alkali metals between graphene layers. Utilizing a high-performance low-voltage (60 kV) electron microscope, they have successfully observed the arrangement structure of alkali metal atoms between the graphene layers. The alkali metals are found densely packed in a two-layer structure in both bilayer graphene and in the surface layer graphite due to the flexible extension ability of their interlayer spacing.

Researchers in Drexel’s College of Engineering, recently reported on the science behind a special concrete, that can warm itself up when it snows, or as temperatures approach freezing.

Chinese researchers are making variations of LK99 room temperature superconductor materials with more sulfur and copper in the chemistry. They are publishing results with stronger magnetic indications of a Meissner effect.

The chinese researchers have been online discussing their room temperature superconducting research and the challenges of the materials.

Here are the issues discussed.

The quest for boundless energy takes an electrifying turn with this magic mineral.

A new material for direct air capture systems turns trapped carbon into baking soda when introduced to seawater.

Incorporating a phase-change material into concrete, researchers have created a self-heating material that can melt snow and ice for up to 10 hours without using salt or shovels. The novel material could reduce the need for plowing and salting and help preserve the integrity of road surfaces.

According to the US Department of Transportation (DOT), more than 70% of roads are in snowy regions. Snow and ice accumulation reduces road friction and vehicle maneuverability, causing drivers to slow and increasing the risk of crashes. Snow-obstructed lanes and roads also reduce roadway capacity and increase travel time.

The DOT states that local and state agencies spend more than US$2.3 billion annually on snow and ice control operations, in addition to the millions spent repairing infrastructure damage caused by snow and ice. Salting is often used before a snow event to prevent icing, but the highly concentrated salt solution can deteriorate concrete or asphalt. In addition, when water seeps into the road and freezes, it expands, causing internal pressure and damaging the road.

Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
