Nanonets Could Convert Sunlight Into Hydrogen

Nanonets Could Convert Sunlight Into Hydrogen

The top image shows a nanonet magnified 50,000 times. At bottom, a
flexible nanonet rolls up when poked by the tip of a scanning tunneling microscope.

One problem with solar cells is that they only produce electricity during the day. A promising way to use the sun’s energy more efficiently is to enlist it to split water into hydrogen gas that can be stored and then employed at any time, day or night. A cheap new nanostructured material could prove an efficient catalyst for performing this reaction. Called a nanonet because of its two-dimensional branching structure, the material is made up of a compound that has been demonstrated to enable the water-splitting reaction. Because of its high surface area, the nanonet enhances this reaction.

Nano-sized “Cargo Ships” Developed To Carry Anti-Cancer Drugs And Markers Through The Body

Nano-sized “Cargo Ships” Developed To Carry Anti-Cancer Drugs And Markers Through The Body 

 The nanometer-sized cargo ships look individually like a chocolate-covered nut cluster, in which a biocompatible lipid forms the chocolate shell and magnetic nanoparticles, quantum dots and the drug doxorubicin are the nuts.

Scientists have developed nanometer-sized ‘cargo ships’ that can sail throughout the body via the bloodstream without immediate detection from the body’s immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected.

Tiny Handlike Gripper Could Make It Easier For Doctors

Tiny Handlike Gripper Could Make It Easier For Doctors

A tiny gripper that responds to chemical triggers could be a new tool for surgery.

A tiny handlike gripper that can grasp tissue or cell samples could make it easier for doctors to perform minimally invasive surgery, such as biopsies. The tiny device curls its “fingers” around an object when triggered chemically, and it can be moved around remotely with a magnet.

Gold Stained Glass Windows An Early Air Purifier

Gold Stained Glass Windows An Early Air Purifier 

 Associate Professor Zhu Huai Yong, from Queensland University of Technology’s School of Physical and Chemical Sciences, said that church windows stained with gold paint purify the air when they are lit up by sunlight.

Scientists have discovered that, in medieval churches, stained glass windows painted with gold purify the air when heated by the sun. The researchers hope that this discovery could also be used for modern technologies, since the chemical reaction involved is very energy-efficient.
