A Device to Control “Color” of Electrons in Graphene Provides Path to Future Electronics
A device made of bilayer graphene, an atomically thin hexagonal arrangement of carbon atoms, provides experimental proof of the ability to control the momentum of electrons and offers a path to electronics that could require less energy and give off less heat than standard CMOS transistors. It is one step forward in a new field of physics called valleytronics.

Subatomic Microscopy Key to Building New Classes of Materials
Researchers at Penn State and the Molecular Foundry at Lawrence Berkeley National Laboratory are pushing the limits of electron microscopy into the tens of picometer scale, a fraction of the size of a hydrogen atom. The ability to see at this subatomic level is crucial in designing new materials with unprecedented properties, such as materials that transition from metals to semiconductors or that exhibit superconductivity.

Chemical Engineers' Research May Lead to Inexpensive, Flexible Solar Cells
Organic solar cells are potentially less expensive and certainly more flexible than the inorganic solar cells made of crystallinesilicon. Although there are several organic solar cells on the market in niche applications, the majority employ fullerene acceptors that are difficult to scale up.

Microencapsulation Produces Uniform Drug Release Vehicle
A new method of delivering anticancer drugs directly to tumors of the brain is being developed by researchers in biomedical and chemical engineering. By encapsulating the drug BCNU in FDA-approved biodegradable polymer microspheres, the drugs can be safely injected into the tumor where they can be controllably released over time. The encapsulation of the drug avoids the side effects from intravenous chemotherapy, which can affect the whole body.

Porous Silicon Developed for Solar Hydrogen Generator
team of Penn State mechanical engineers led by Donghai Wang has reported a new method for making porous silicon with nanoscale pores. Because of the reactivity of silicon to sunlight and the large surface area created by the pores, the material can act as a strong catalyst to break the molecular bonds of water when exposed to sunlight.

Synthetic Polymers Enable Cheap, Efficient, Durable Alkaline Fuel Cells
Current proton exchange membrane fuel cells (PEMFC) require expensive catalysts, such as platinum, combined with perfluorinated membranes and corrosion-resistant cell hardware, all of which drive up the cost. Michael Hickner’s (associate professor of materials science and engineering) membrane was developed to be used in an alkaline fuel cell, which can operate with non-noble metals or inexpensive metal oxides as catalysts, greatly reducing the cost of the devices.

Strongly Interacting Electrons in Wacky Oxide Synchronize to Compute Like the Brain
A device created by electrical engineers at Penn State uses a thin film of VO2 on a titanium dioxide substrate to create an oscillating switch. Ph.D. student Nikhil Shukla added a second similar oscillating system and discovered that over time the two devices began to oscillate in unison. This coupled system could provide the basis for non-Boolean computing similar to the way the brain functions.
