Research News: The state-of-the-art of piezoelectric energy harvesting

The global energy crisis and environmental pollutions caused mainly by the increased consumption of nonrenewable energy sources prompted researchers to explore alternative energy technologies that can harvest energies available in the ambient environment. Mechanical energy is the most ubiquitous ambient energy.Piezoelectric transduction is the prominent mechanical energy harvesting mechanism, Thus, piezoelectric energy harvesting has received the utmost interest by the scientific community.Advancements of micro and nanoscale materials and manufacturing processes have enabled the fabrication of piezoelectric generators.

Research News: Bamboo inspires faster battery recharging

Scientists from Queensland University of Technology have developed a new way to boost the efficiency of batteries with electrodes that can be recharged at a much faster rate based on the unique properties of bamboo. The study, which furthers research into 2D nanomaterials for the very fast transport of ions through a battery, was inspired by a water-carrying membrane inside bamboo that allows it to be the fastest growing plant in the world.

The lab of Ziqi Sun has been studying how best to mimic the structural and optical properties of natural objects – such as seashells that have inspired advanced optical thin films, fish scales that have inspired multifunctional nano-coatings – to develop sustainable energy solutions from low-dimensional nanomaterials.

Research News: A new perspective on the application of nanomaterials to tumors

What is the nanomaterial?

Nanometer materials refer to materials whose structural unit sizes are in the range of 1 nanometer to 100 nanometers. This new type of material was discovered by scientists in the middle of the last century. Due to its unique size and structure, this new type of material has acquired unusual capabilities.

Research News: Emission Properties of Carbon Nanotubes

One of the most promising applications of CNTs is in field emission (FE) devices. High aspect ratio and atomically sharp radius of apex curvature of the CNTs enhance the local field and lower the threshold field for electron emission.

Research News: Advances and Applications of Diamond-like Nanocomposite

Diamond-like Nanocomposite (DLN) coatings are amorphous, hard and wear resistant coatings, deposited using a plasma-assisted CVD process. These coatings consist of two interpenetrating networks, one being a diamond-like carbon (a-C:H) network and the other a glass-like a-Si:O network.

Research News: Nanocomposites are an important resource in the 21st century

In recent years, advances in nanotechnology have promoted the development of reinforcements with dimensions at the nano-scale (10−9 m). This dimensional shift has opened new possibilities for altering physical properties of polymer matrices (mechanical, electrical, thermal, etc.) by incorporating relatively small amounts of nanofillers (several weight percent or less) .

Research News: Illinois engineers protect artifacts by graphene gilding

Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding—and these golden sculptures have resisted corrosion, wear, and environmental degradation for thousands of years. The middle and outer coffins of Tutankhamun, for instance, are gold leaf gilded, as are many other ancient treasures.

In a new study, Sameh Tawfick, an assistant professor of Mechanical Science and Engineering at the University of Illinois at Urbana-Champaign, inspired by this ancient , has added a single layer of carbon atoms, known as , on top of  leaves—doubling the protective quality of gilding against wear and tear.

Research News: Carbon nanodots do an ultrafine job with in vitro lung tissue

Epidemiological studies have established a strong correlation between inhaling ultrafine particles from incomplete combustion and respiratory and cardiovascular diseases. Still, relatively little is known about the mechanisms behind how air particulates affect human health. New work with carbon nanodots seeks to provide the first model of how ultrafine carbon-based particles interact with the lung tissues.

An international group of researchers created a 3-D lung cell model system to investigate how carbon-based combustion byproducts behave as they interact with human epithelial . In Biointerphases, an AVS journal, the investigators discovered that the surface properties of the carbon nanodot's properties and aggregation patterns affected their distribution in a lab-grown copy of the lung's barrier layer, the epithelium. The carbon nanodots served as representatives for air pollution particles.

Research News: Chemists develop nanocatalysts for continuous biofuel synthesis

A chemist from RUDN synthesized new catalysts with ruthenium (Ru) nanoparticles for producing biofuel from organic biowaste. Nanocatalysts support more intensive and sustained reactions than the compounds currently available in the market. The results of the study were published in the ChemSusChem journal.

Rafael Luque, an external specialist from RUDN, works on the synthesis of gamma-valerolactone (GVL) together with his Chinese and Spanish colleagues. This colorless liquid can be obtained from food waste or harvesting leftovers. GVL may be used as a safe solvent or an additive to gasoline or may be distilled into hydrocarbons, "green fuel" for internal combustion engines.
