U.S. Senate Weighs Big Plans for Small Reactors

by Rahul Rao in Energy, Engineering, Engineering News

Small modular reactors (SMRs) power many of today’s nuclear enthusiasts’ clean-energy dreams. SMRs promise to be cheaper and nimbler than their far larger counterparts within today’s nuclear power plants. Countries from Britain and France to Ghana and Indonesia have shown interest in linking SMRs to the grid for the 2030s and beyond. In the U.S., […]

Supercapacitors Get Smaller Than Ever

by Rahul Rao in Energy, Engineering, Engineering News

As smart devices, wearable sensors, IoT technologies, and implantable electronics shrink in size, so too should the energy storage devices they rely on. Supercapacitors—with high capacity for energy storage but also a capability to handle rapid charge-discharge cycles that would founder a conventional chemical battery—have in recent years shrunk to “micro” size. Now researchers in […]

World’s Largest Biofuel Program Places a Risky Bet

by Rahul Rao in Energy, Engineering, Engineering News

The U.S. Environmental Protection Agency runs the world’s largest biofuel program: the Renewable Fuel Standard (RFS). On its surface, the RFS requires providers of U.S. transportation fuel to blend in a certain quota of fuels from renewable sources. But when is a renewable fuel not renewable? On 23 February, ProPublica reported that the agency gave […]

The Future of Fission Reactors May Be Small

by Rahul Rao in Engineering, Engineering News

On the island of Hainan, south China, one possible future is taking shape within a compact labyrinth of concrete and metal. Last July, a crane hoisted the upper half of a steel containment shell into place. Slowly, steadily, workers are piecing together a miniature nuclear reactor. This is Linglong One, whose diminutive size is a […]

The World’s Largest Camera Is Nearly Complete

by Rahul Rao in Engineering, Engineering News

The world’s largest camera sits within a nondescript industrial building in the hills above San Francisco Bay. If all goes well, this camera will one day fit into the heart of the future Vera C. Rubin Observatory in Chile. For the last seven years, engineers have been crafting the camera in a clean room at […]

Modeling Thermal Management Systems for Electronics

by Rahul Rao in Engineering, Engineering News

The ability to dissipate heat is one of the most important features of modern electronic devices and is usually a limiting factor in the miniaturization of these devices. COMSOL Multiphysics includes functionality for heat transfer through conduction, convection, and radiation. Its ability to treat conjugate heat transfer, including laminar and turbulent flow as well as […]

Converting Coal Power Plants to Nuclear Gains Steam

by Rahul Rao in Engineering, Engineering News

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past. In the United States, […]

Government’s Role in Further Developing 5G Technologies and Future Networks

by Rahul Rao in Engineering, Engineering News

Similar to 5G, many key technology developments have been supported by government funding and institutions for years. Federally Funded Research and Development Centers (FFRDC) and University Affiliated Research Centers (UARC) have been foundational elements of this government support. This webinar will examine the impact this research has had on national security and the overall economy. […]

This AI Could Be Robocallers' Kryptonite

by Rahul Rao in Engineering, Engineering News

Last year, the U.S. government got serious about snuffing out robocalls. Effective 30 June 2021, the FCC mandated that phone providers verify all callers’ IDs with a cryptography-based protocol called STIR/SHAKEN. Anyone expecting robocalls to vanish in a puff of regulation will be disappointed. But relief may be coming, gradually. The technology to block robocalls […]
