3-D printed batteries handle the squeeze

While flexible and stretchable electronics technologies have progressed in leaps and bounds over the past 10 years, batteries to power them have some catching up to do. Researchers in Singapore and China have now demonstrated ...

Regulating the absorption spectrum of polydopamine

Polydopamine (PDA) is an advanced functional material and its emergent light absorption properties make it crucial for applications in materials science. However, it is challenging to rationally design and regulate PDA absorption ...

Fish-inspired material changes color using nanocolumns

Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material.

Trisulfur anion helps explain gold deposits on Earth

(Phys.org)—People have been excavating gold for thousands of years as a precious rare metal. Gold is in relatively low abundance in the Earth's crust likely coming from the metallic core and from meteorites. For reasons ...

Safer way to make diazomethane developed

(PhysOrg.com) -- Diazomethane is a toxic, explosive reagent prepared as needed in laboratories, where it is commonly used in cyclopropanation, but its explosive nature prevents it being used widely on an industrial scale. ...

Going platinum: New catalyst could boost cleaner fuel use

(PhysOrg.com) -- Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts. ...

Programming pH: New technique could accelerate DNA synthesis

pH—the concentration of protons in a watery solution—indicates how acidic the solution is. It regulates a broad range of natural and engineered chemical processes, including the synthesis of designed DNA sequences for ...
