A Low-Cost Manufacturing Solution for CIGS-Based Solar Cells

Though the solar industry today predominately produces solar panels made from crystalline silicon, they remain relatively expensive to make. New players in the solar industry have instead been looking at panels that can harvest energy with CIGS (copper-indium-gallium-selenide) or CIGS-related materials.

First Step in Converting Solar Energy Using Artificial Leaf

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team, headed by Leiden University professor Huub de Groot, modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria.

Monitoring Plutonium Contamination

Five years from now, scientists will be able to better determine how, when, and why plutonium moves in soil and groundwater. The way to predict how plutonium is transported in groundwater away from a site is by looking at the dominant geochemical processes that control plutonium's (Pu) behavior in the subsurface at environmental levels. But that isn't always so easy.

Feather Fibers Fluff Up Hydrogen Storage Capacity

Scientists have developed a new hydrogen storage method - carbonized chicken feather fibers - that can hold vast amounts of hydrogen, and do it at a far lower cost than other hydrogen storage systems. The research could help overcome some of the hurdles to using hydrogen fuel in cars, trucks, and other machinery.

Sensing Method Checks Refrigerant Levels, Saves Energy

A new “virtual refrigerant charge sensor" saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime. Engineers at Purdue University developed the sensing technique, which is particularly practical for automotive air conditioners.

Computing Cost-Effective Pollution Control Strategies

A new tool could help in choosing the best ways to control pollution on even the smallest of waterways. The tool analyzes data from an area, and can compute the most cost-effective pollution-control strategies for water resources affected by agriculture in just a few hours - a process that currently takes weeks or months.
