Enhanced photocatalytic activity by Cu2O nanoparticles integrated H2Ti3O7 nanotubes

Tue, 20/06/2017 - 1:31pm
Compositing Cu2O nanoparticles with H2Ti3O7 nanotubes provides an effective strategy to reduce the bandgap energy and the recombination of photo-generated electrons and holes. There is an obvious synergistic effect between guest nanoparticles and host nanotubes due to the interaction to form heterojunction struction, which will enhance photocatalytic oxidation performance for removal of EM due to the stronger visible spectral response and wider absorbance in the long visble light region.

Nanoparticle based contrast agent developed for dual modal imaging of cancer

Tue, 20/06/2017 - 1:31pm
Dual modal imaging which shares the advantages of two imaging modalities such as magnetic resonance imaging and optical imaging, has the ability to produce images with higher spatial resolution and higher sensitivity. Contrast agents having both magnetic and optical properties identifies the cancer cells efficiently. Europium doped gadolinium oxide nanorods were synthesized and subsequently coated with silica to improve the biocompatibility.

A wooden toe: Swiss Egyptologists study 3000-year-old prosthesis

Tue, 20/06/2017 - 1:31pm
It is likely to be one of the oldest prosthetic devices in human history: Together with other experts, Egyptologists have reexamined an artificial wooden big toe. The find is almost 3000 years old and was discovered in a female burial from the necropolis of Sheikh ´Abd el-Qurna close to Luxor. This area is currently being studied using state-of-the-art methods.

Freshwater from salt water using only solar energy

Mon, 19/06/2017 - 8:54pm
A federally funded research effort to revolutionize water treatment has yielded a direct solar desalination technology that uses energy from sunlight alone to heat salt water for membrane distillation. The technology could provide off-grid water treatment for some of the 1 billion people who lack access to clean water.

Fighting global warming and climate change requires a broad energy portfolio

Mon, 19/06/2017 - 7:22pm
Can the continental United States make a rapid, reliable and low-cost transition to an energy system that relies almost exclusively on wind, solar and hydroelectric power? While there is growing excitement for this vision, a new study describes a more complicated reality. Researchers argue that achieving net-zero carbon emissions requires the incorporation of a much broader suite of energy sources and approaches.

Tiny fossils reveal backstory of the most mysterious amphibian alive

Mon, 19/06/2017 - 7:15pm
The fossils of an extinct species from the Triassic Period are the long-missing link that connects Kermit the Frog's amphibian brethren to wormlike creatures with a backbone and two rows of sharp teeth, new research shows. Named Chinlestegophis jenkinsi, the newfound fossil is the oldest relative of the most mysterious group of amphibians: caecilians. Today, these limbless, colorful serpentine carnivores live underground and range in size from 6 inches to 5 feet.
