The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems.

Lithium ion batteries (LIBs) have many advantages but there are much more abundant metallic elements available such as sodium, potassium, zinc and aluminum.

These elements have similar chemistries to lithium and have recently been extensively investigated, including sodium-ion batteries (SIBs), potassium-ion batteries (PIBs), zinc-ion batteries (ZIBs), and aluminum-ion batteries (AIBs). Despite promising aspects relating to redox potential and energy density the development of these beyond-LIBs has been impeded by the lack of suitable electrode materials.

Samsung’s latest scientific breakthrough might change the very way we perceive semiconductors, largely on account of the fact it’s two-dimensional. Called amorphous boron nitride (a-BN), the substance in question is composed of but a single layer of atoms and characterized by an amorphous (liquid-like) molecule structure. It’s also the best 2D material for insulation ever synthetized, with Samsung hoping it will be able to utilize in production of revolutionary graphene wafers with unprecedentedly low level of electrical interference.

The discovery of a-BN is hardly Samsung’s first foray into 2D materials. The first and possibly most famous such substance — graphene — has been the subject of countless projects at the Korean conglomerate ever since it was first isolated in 2004. Following the 2016 Galaxy Note 7 fiasco, Samsung is believed to have doubled down on graphene R&D with the goal of eventually integrating the 2D material into its batteries, making them more stable, i.e. less prone to spontaneous combustions.

Making graphene batteries is no small feat, however, and it’s been a while since Samsung last made significant inroads on that front. Scalability remains a key issue, particularly in regards to mass-production costs. Graphene wafers, on the other hand, are expected to play a major role in the development and volume production of next-generation server memory modules, as well as DRAM and NAND memory chips.

New UCLA research conducted in mice could explain why some people suffer more extensive scarring than others after a heart attack. The study, published in the journal Cell, reveals that a protein known as type 5 collagen plays a critical role in regulating the size of scar tissue in the heart.

Once formed, heart scar tissue remains for life, reducing the heart’s ability to pump blood and adding strain to the remaining heart muscle. People who develop larger scars have a higher risk of heart rhythm problems, heart failure and sudden cardiac death.

TuSimple, a trucking technology company, has announced a plan for the world’s first Autonomous Freight Network (AFN) – an ecosystem consisting of autonomous trucks, digital mapped routes, strategically placed terminals, and TuSimple Connect, a proprietary autonomous operations monitoring system.

Collectively, these components will work together to create the safest and most efficient way to bring self-driving trucks to market. Partnering with TuSimple in the launch of the Autonomous Freight Network are UPS, Penske Truck Leasing, U.S. Xpress (who operate one of the largest carrier fleets in the country) and McLane, a Berkshire Hathaway company and one of the largest supply chain services leaders in the United States.

“Our ultimate goal is to have a nationwide transportation network, consisting of mapped routes connecting hundreds of terminals to enable efficient, low-cost, long-haul autonomous freight operations,” said Cheng Lu, President of TuSimple. “By launching the AFN with our strategic partners, we will be able to quickly scale operations and expand autonomous shipping lanes to provide users access to autonomous capacity anywhere and 24/7 on-demand.”
