Physics, photosynthesis and solar cells

Researchers combine quantum physics and photosynthesis to make discovery that could lead to highly efficient, green solar cells.

Controlled electron pulses

Scientists have successfully measured photoemission from sharp metal needles on a scale never before achieved.

Tailor-made membranes for the environment

By inserting foreign atoms into the crystal lattice, a novel membrane is more stable and can be used at lower temperatures. However, the greatest achievement is the increased hydrogen flow.

Microbubbles and ultrasound open the blood?brain barrier to administer drugs

Scientists have succeeded in embedding medicines in tiny lipid bubbles, in such a way that ultrasound can be used to release them into the specific area of the brain where they are needed.

Creating new physical properties in materials

A collaborative effort between research groups demonstrates that the physical properties of SrTiO3, or strontium titanate, in its single crystal form can be changed by a relatively simple electrical treatment. SrTi03 is a mineral often studied for its superconducting properties.

A nanotechnology method for storing vaccines at room temperature

Using minute quantities of nanoparticles, or FDA-approved polymer (polyethylene glycol), or higher amounts of sucrose, researchers were able to stabilize vaccines at room temperature for several weeks or, in some cases, months.

Quantum obstacle course changes material from superconductor to insulator

Scientists ave demonstrated an unusual method of putting the brakes on superconductivity, the ability of a material to conduct an electrical current with zero resistance.

Understanding the way liquid spreads through paper

Researchers have created a model to explain how liquid diffuses through paper which has applications in medical testing and perfume manufacturing.

Mix and match lasers

Combining silicon with an optically active material enables tiny lasers compatible with industrial fabrication techniques.

Throwing new light on printed organic solar cells

Researchers have achieved record power conversion efficiencies for large area organic solar cells.
