Figure 1a and 1b. Due to the limited access for repair and maintenance of base station and cell towers, long life operation is required
Temperature control of sensitive telecom electronics in unattended mobile base stations and cell towers is vital for the operation of primary and back-up systems. Heat can significantly degrade the performance and operating life of telecom cabinets, energy storage systems and back-up battery systems. Mobile

Figure 1: DC-DC converters can be isolated or non-isolated
When Allesandro Volta made a battery out of copper and zinc disks and brine-soaked cardboard, it was a novelty and the low power DC produced had few practical applications. As electricity became better understood and it was discovered that rotating magnets could induce AC current in wires, the world of power

Figure 1: Average plant response to PAR
The horticultural lighting industry is in the middle of a disruptive change – growers are now getting to grips with the LED ‘solid-state’ artificial light alternative, traditionally provided by high-pressure sodium lamps (HPS). HPS lamps are relatively efficient at 100-150 lumens per watt, actually similar

Next-generation ammonia-salt based pretreatment processes facilitate efficient breakdown of waste biomass such as corn stalks, leaves and other residue (called corn stover).
Researchers have developed a new process that could make it much cheaper to produce biofuels such as ethanol from plant waste and reduce reliance on fossil fuels.
Their approach, featuring an ammonia-salt based solvent that rapidly turns plant fibers into sugars needed to make ethanol, works well

Researchers will work to improve the solar cell's back contact, the layer furthest from the light source.
Fifty years ago, solar power was rare, expensive and specialized - barely a blip on the energy landscape. Today, rooftop and commercial solar markets are exploding, generating 2.5% of all electricity in the U.S. and fueled by the urgency of climate change.
For many years, Colorado State University
