Ultra-Stable Perovskite Solar Cell Remains Stable for Over a Year

Perovskite solar cells promise cheaper and efficient solar energy, with enormous potential for commercialization. But even though they have been shown to achieve over 22{261f6ead6a0f3cabae584e9904bae8bd53a3c91c6c837aa2d58453541104ad2d} power-conversion efficiency, their operational stability still fails market requirements. Despite a number of proposed solutions in fabrication technology, this issue has continued to undercut whatever incremental increases in efficiency have

New Material for Splitting Water Could Make Hydrogen Production Cheaper

UNSW chemists have invented a new, cheap catalyst for splitting water with an electrical current to efficiently produce clean hydrogen fuel. UNSW chemists have invented a new, cheap catalyst for splitting water with an electrical current to efficiently produce clean hydrogen fuel. The technology is based on the creation of ultrathin slices of porous metal-organic

Researchers Create 3-D Printed Tensegrity Objects Capable of Dramatic Shape Change

A team of researchers from the Georgia Institute of Technology has developed a way to use 3-D printers to create objects capable of expanding dramatically that could someday be used in applications ranging from space missions to biomedical devices. The new objects use tensegrity, a structural system of floating rods in compression and cables in

The Ethics of Using Brain Implants to Upgrade Yourself

Neurotechnology is one of the hottest areas of engineering, and the technological achievements sound miraculous: Paralyzed people have controlled robotic limbs and computer cursors with their brains, while blind people are receiving eye implants that send signals to their brains’ visual centers. Researchers are figuring out how to make better implantable devices and scalp electrodes

Army Brings Back Stinger Missile in Face of Russian Aggression

The Army has intensified the training soldiers receive on the FIM-92 Stinger — a man-portable, air defense missile — after nearly 15 years of moving away from the weapon system. The Stinger has been around since the late 1970s, according to the Army. As counterinsurgency became the Army’s primary mission focus, however, training drifted away

NATO Nations Testing Equipment Interoperability

The most recent event in a series of coalition capability demonstrations is helping to ensure that equipment from NATO countries are able to work together, according to military officials from participating nations. John Miller, the event’s program manager assigned to the U.S. Joint Staff command and control, communications and computers/cyber directorate, told reporters during an

Inexpensive and Stable – the Salt Water Battery

Water could form the basis for future particularly inexpensive rechargeable batteries. Empa researchers have succeeded in doubling the electrochemical stability of water with a special saline solution. This takes us one step closer to using the technology commercially. In the quest to find safe, low-cost batteries for the future, eventually we have to ask ourselves

The Complexity of Multi-Domain Operations

For the U.S. military to maintain its status as the greatest fighting force in the world, it must continue to learn and understand the multi-domain battlespace and significantly improve its operations across the entire range of military activity. It is widely believed that the U.S. military is exceptional and by far the best in the

Did a Warhead’s Refurbishment Enhance its Military Capabilities?

In a brief press release last month, the US Department of Energy’s National Nuclear Security Administration (NNSA) announced it had completed, on time and within budget, the manufacturing of a key replacement component for submarine-launched nuclear warheads. What the release didn’t say is how the new device reportedly dramatically increases the capability of refurbished weapons

Scientists Designed an Instrument to Identify Unexploded Artillery Shells

Society faces threats through the malicious use of chemical, biological, radiological, nuclear and/or explosive (CBRNE) materials. The detection of illicit trafficking or other criminal acts, as well as many security and safety applications, call for novel material analysis techniques and instruments. These detection systems should be non-destructive but still be able to detect and identify

Misconfigured Communications Equipment Prevents Rocket Lab’s First Test Rocket from Reaching Orbit

Aerospace startup Rocket Lab says it knows why the first test launch of its small rocket failed to reach orbit in May. The failure had nothing to do with the rocket itself, but instead the mission was terminated early because of a problem with ground equipment supporting the launch. Now that Rocket Lab knows what

Scientists Develop Ultrafast Battery with Quarter-Million Cycle Life

Aluminum-ion batteries (AIB) have significant merits of low cost, non-flammability, and high-capacity metallic aluminum anodes based on three-electron redox properties. However, due to its inadequate cathodic performance, especially in terms of capacity, high-rate capability, and cycle life, AIB still cannot compete with Li-ion batteries and supercapacitors. To address these issues, a research team led by
