Scientists Develop Groundbreaking Sensor That Can Wirelessly Detect Chemical Warfare Agents
Posted by Genevieve Klien in categories: chemistry, energy, military
Researchers have developed a revolutionary sensor capable of detecting chemical warfare agents without wires, representing a major advancement in technology for public safety. This innovative device, capable of identifying substances like dimethyl methylphosphonate (DMMP), offers a new level of efficiency and reliability in monitoring and responding to chemical threats, without the need for direct power sources or physical connections.
The urgent need for advanced detection of chemical warfare agents (CWAs) to ensure global security has led to the development of a novel gas sensor. This sensor is distinguished by its rapid response, high sensitivity, and compact size, crucial for the early detection of CWAs. Accurate detection and monitoring of CWAs are vital for effective defense operations, both military and civilian. Due to the hazardous nature of CWAs, research is typically limited to authorized laboratories using simulants that mimic CWAs’ chemical structure without their toxic effects.

Scientists proved the fundamental limits of electromagnetic energy absorption
Posted by Shailesh Prasad in categories: energy, mathematics
Until recently, researchers were unsure of the minimum thickness of a transparent substance required to take in a given quantity of light.
Konstantin N. Rozanov of the Institute for Theoretical and Applied Electrodynamics in Russia discovered more than two decades ago the amount of light that a gadget might absorb at various wavelengths if one side of it was coated in metal. This metal establishes a barrier where light is absorbed or bounced back, simplifying the mathematical solution.

MIT Unveils the Dance of Protons: Pioneering Energy’s New Era
Posted by Saúl Morales Rodriguéz in categories: chemistry, energy
New insights into how proton-coupled electron transfers occur at an electrode could help researchers design more efficient fuel cells and electrolyzers.
A key chemical reaction — in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current — is a critical step in many energy technologies, including fuel cells and the electrolyzers used to produce hydrogen gas.
For the first time, MIT chemists have mapped out in detail how these proton-coupled electron transfers happen at an electrode surface. Their results could help researchers design more efficient fuel cells, batteries, or other energy technologies.

Unlocking the Future of Microelectronics With Argonne’s Redox Gating Breakthrough
Posted by Saúl Morales Rodriguéz in categories: energy, quantum physics
Argonne researchers pioneer “redox gating” — a new way to precisely modulate electron flow.
Breakthrough could help lead to the development of new low-power semiconductors or quantum devices.
As the integrated circuits that power our electronic devices get more powerful, they are also getting smaller. This trend of microelectronics has only accelerated in recent years as scientists try to fit increasingly more semiconducting components on a chip.

Measurement of non-monotonic Casimir forces between silicon nanostructures
Posted by Quinn Sena in categories: chemistry, energy, nanotechnology, physics
Like Brian Greer has said the casimir technologies can power anything and create a free society a free utopia without the need for using any chemicals and it has been known since the 1950s in the physics community.
Previous demonstrations of the elusive Casimir force between interfaces exhibit monotonic dependence on surface displacement. Now a non-monotonic dependence of the force has been shown experimentally by exploting nanostructured surfaces.

US researchers determine the limits of energy absorption in transparent materials
Posted by Gemechu Taye in categories: energy, mathematics
Duke researchers find limits of energy absorption in transparent materials.
Researchers at Duke University in the US have determined the theoretical limits of how much electromagnetic energy a transparent material can absorb. This can help researchers optimize device designs in the future, but it has also ended a 20-year wait for a mathematical solution to the problem.

Study shows inverting fusion plasmas improves performance
Posted by Genevieve Klien in category: energy
To become commercially viable, fusion power plants must create and sustain the plasma conditions necessary for fusion reactions. However, at high temperatures and densities, plasmas often develop gradients in those temperatures and densities. These gradients can grow into instabilities such as edge localized modes (ELMs).
