Making ferromagnets stronger by adding non-magnetic elements
Fri, 23 Jun 2017 15:55:14 EDT
Magnetic materials can be functionalized through a thoroughly unlikely method, report researchers: by adding amounts of the virtually non-magnetic element scandium to a gadolinium-germanium alloy.
A unique amino acid for brain cancer therapy
Fri, 23 Jun 2017 08:50:53 EDT
Photodynamic therapy is often used to treat brain tumors because of its specificity — it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light. When the photosensitizer is exposed to this light, it emits what is known as a reactive oxygen species (ROS) that causes the cells to die.
How a single chemical bond balances cells between life and death

With SLAC's X-ray laser and synchrotron, scientists measured exactly how much energy goes into keeping a crucial chemical bond from triggering a cell's death spiral.
Catalyst mimics the z-scheme of photosynthesis

A new study demonstrates a process with great potential for developing technologies for reducing CO2 levels.
New efficient, low-temperature catalyst for hydrogen production
Thu, 22 Jun 2017 14:29:56 EDT
Scientists have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO). The discovery could improve the performance of fuel cells that run on hydrogen fuel but can be poisoned by CO.
