As power grids add more renewable energy and large-scale battery storage, utilities face a growing challenge: how to stress-test tomorrow’s electricity systems before investing billions to build them. Wind, solar and battery-backed grids behave differently […]

A research team affiliated with UNIST has demonstrated that liquid electrolytes, when frozen, can still facilitate lithium-ion conduction sufficient for battery operation—challenging the traditional view that electrolytes must be in liquid form to function. The […]

Scientists from Tokyo Metropolitan University have discovered that a hydrogen-absorbing material shrinks in one direction upon heating, so-called negative thermal expansion (NTE). They found that this NTE is driven by a phase transition in the […]

Engineers at Oxford University have developed a rapid, ultra-low-cost method for manufacturing soft robots using common lab equipment. The method has been published in Advanced Science. The new technique enables researchers to fabricate soft robotic […]

The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of which can overheat under stress, causing steep drops in performance. To address this, a team led by researchers at […]

A study involving the IIAMA Institute at the Universitat Politècnica de València (UPV) proposes a series of solutions to address a critical engineering problem: unforeseen water leaks during the construction of deep excavations. The work, […]

The human body continuously generates a rich spectrum of vibrations—often without us ever noticing. Everyday unconscious activities such as breathing, speaking, and swallowing all produce subtle yet distinct mechanical signals. Although these faint vibrations carry […]

Rechargeable batteries are everywhere—from portable electronic devices and electric vehicles to renewable energy storage. Battery failures are often due to the loss or chemical degradation of the electrolyte.This post was originally published on this site

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching sensors to the inspection target. By enabling […]

Purdue University engineers have developed a patent-pending method to decrease hazardous strikes to underground utility pipes during construction projects. This could lower related financial losses, service disruptions, injuries and fatalities.This post was originally published on […]
