Glass as Electrode Makes Batteries More Efficient

Today’s batteries provide a reliable power supply for our smartphones, electric cars and laptops, but are unable to keep up with the growing demands placed on them. Researchers have discovered a material that may have the potential to double battery capacity: vanadate-borate glass. The glass is being used as a cathode material, which is made of vanadium oxide (V2O5) and lithium-borate (LiBO2) precursors, and was coated with reduced graphite oxide (RGO) to enhance the electrode properties of the material. The vanadate-borate glass powder was used for battery cathodes, which were placed in prototypes for coin cell batteries to undergo numerous charge/discharge cycles. In tests, the glass electrodes demonstrated a vast improvement in these batteries’ capacity and energy density. Source:

Negative Dielectric Constant Material Based on Ion-Conducting Materials

Langley Research Center, Hampton, Virginia Metamaterials, or artificial negative index materials (NIMs), have generated great attention due to their unique and exotic electromagnetic properties. A negative dielectric constant material, which is an essential key for creating the NIMs, was developed by doping ions into a polymer, a protonated poly(benzimidazole) (PBI).

Energy Efficiency in Machine Tools

Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock removal rate, while the power consumption during finishing is significantly lower. There is a very close interdependence between the individual components and subassemblies of a machine tool and aspects of productivity and quality. From a detailed examination of manufacturing processes to the power consumption of individual components, potential for savings can be evaluated and measures can be defined for the efficient use of energy.

Energy Harvesting Could Help Power Spacecraft of the Future

A consortium is working on a project to maximize energy harvesting on a spacecraft of the future. The initiative seeks to find energy-saving and -maximizing solutions to enable eco-friendly aircraft to stay in space for long periods of time without the need to return to Earth to re-fuel, or to avoid carrying vast amounts of heavy fuel on long-stay journeys.

Variable-Sweep-Wing Aircraft Configuration

There are significant improvements in structural, aerodynamic, and energy efficiency. Ames Research Center, Moffett Field, California Efficient aircraft designs are increasingly desired in order to support the continued growth of the air transportation industry. Continued expansion of this vital mode of transportation is threatened due to concerns over ever-increasing emissions, noise, and the demand for fuel. Current airport runway, ramp, and terminal facilities are increasingly constrained by encroaching growth and neighborhood environmental issues. The challenges associated with ever-increasing demand for air travel will require the development of aircraft that can fly efficiently over wide speed ranges, minimize their environmental impacts, offer the potential for sizing and growth relative to market demand, and make efficient use of constrained airport and airspace resources.

Foldable Material Can Support Many Times its Weight

Researchers at Drexel University and Dalian University of Technology in China have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration, and radio frequency shielding in technology from portable electronics to coaxial cables.
