Credit: CC0 Public Domain Sodium-metal batteries (SMBs) are one of the most promising high-energy and low-cost energy storage systems for the next-generation of large-scale applications. However, one of the major impediments to the development of SMBs is uncontrolled dendrite growth, which penetrate the battery’s separator and result in short-circuiting. Building on previous work at the…

The industry has expanded rapidly worldwide and further growth is expected. This has contributed to a great deal more construction waste being generated—which has been identified as one of the core problems in the construction industry across the world….

As a result, traditional radio-based wireless communication, in other words WiFi, will struggle to meet…

This data visualization compares the land required for different kinds of power generation. Nuclear power, with its extremely energy-dense fuel, is the smallest by far. Credit: Good Energy Collective With no-wind-turbine signs on roadsides next to cornfields, it’s hardly surprising that land use is a thorny issue for renewables. But how much land do different…

Credit: Environmental Science: Advances One of the leading causes of water pollution is heavy metal contamination which has profound adverse effects on human health and the environment. That’s why Clarkson University researchers have developed a cost-effective, 3D printing technology to create sustainable bio-based adsorbents that can effectively remove toxic heavy metal ions from contaminated environments….

Shocking images of the burnt rail bridge and collapsed road bridge have been shown around the world. But Russia has moved quickly to return the bridge to operations, even…

Credit: Pixabay/CC0 Public Domain Permanent magnet synchronous motor (PMSM) systems have been widely used due to their high power density and high efficiency. Digital control systems have been applied to improve the performance of PMSM systems. Proportional integral control, as a straightforward and effective control method, has been implemented on the microprocessors to manipulate PMSM…
