Hierarchical Porous Titanium Nitride

A team of researchers at Korea Advanced Institute of Science and Technology (KAIST) has recently created high-rate, ultra-stable lithium-sulfur batteries (LSBs) by employing hierarchically porous titanium nitride (h-TiN) as a host material for sulfur. It achieved high-rate performance and excellent cycle stability for LSBs. The control of massive amounts of energy is needed for use in smart grid systems and electric vehicles. To that end, there had been an increasing


Efficient recycling process is of high importance to reduce the amount of plastics being dumped in the landfills. Currently, it is not economically viable to sort plastics to enable their recycling. Many plastics, for example, contain flame retardants to resist ignition, reduce flame spreading, minimize smoke formation, and prevent them from dripping. Quantity and types of flame retardants added to plastics may vary considerably, due to the need to tailor


Organic polymers find wide application in LEDs, sensors, solar cell, and other products. One particular type of polymers called ‘S-PPVs’ were theoretically regarded as promising but it was almost impossible to generate these polymers from a technical perspective. After years of work, a group of researchers at TU Wien has successfully identified a new chemical synthesis process to produce S-PPVs, which has now been patented. Sulfur (S-PPVs) over Oxygen (O-PPVs)

Hierarchical Porous Titanium Nitride

A group of researchers at the Boise State University has recently released an open-source design of a chemical vapor deposition (CVD) system for developing two-dimensional materials, an advance which could overcome challenges in 2D materials research and accelerate their discovery, and enable translation from benchtop to commercial market. The pioneering work on 2D materials (one to a few atoms thick) involved isolating and determining the physical properties of graphene –

Hierarchical Porous Titanium Nitride

A team of researchers has recently created a new bio-composite material using date palm fiber biomass, which is potential for sustainable, lightweight, and low-cost applications in automotive and marine industries for non-structural parts such as door linings and car bumpers. Unlike synthetic composites reinforced by glass and carbon fibers, the polycaprolactone (PCL) bio-composite reinforced by date palm fiber is completely renewable, recyclable, biodegradable, and sustainable, according to researchers whose work has

Smart Textiles

Scientists have recently developed thin, flexible wires with silver that may find potential application in comfortable wearable electronics and smart textiles. A group of researchers at China’s Nanjing University of Posts and Telecommunications have built a simple, scalable, and inexpensive technique to produce conductive fibers with good mechanical strength, high conductivity, and uniform morphology. Owing to capillary actions of fibers including nylon, cotton, and polyester yarns, the solution containing nanowires

Hypersonic Vehicles

Hypersonic vehicles can be an airplane, missile, or spacecraft that travel through the atmosphere at extremely high speeds. These vehicles create intense friction with the surrounding air, as they fly at speeds above Mach 5 which is five times faster than the speed of sound. It is technically challenging to develop structure that can withstand furnace-like temperature at such incredible high speed, especially for leading edges that bear the maximum

Lignin Composites

Scientists from the Oak Ridge National Laboratory (ORNL) have discovered that a by-product of biorefinery processes called – lignin composites; could serve as renewable 3D printing feedstock. The new discovery has been outlined in the journal Science Advances, which extends ORNL’s achievements in the reducing the cost of bio-products by creating profitable new uses of lignin. The lignin is a form of complex organic polymers that creates structural materials in

Plastic Waste

Researchers at the Lund University have made new discoveries that plastic waste in the environment degenerates into nano-sized particles called ‘nanoplastics’. In order to mimic the degradation of plastic in the ocean, the researcher subjected takeaway coffee cup lids to mechanical breakdown. Most of the marine debris is plastic and calculations have revealed that around 10 percent of all plastic produced worldwide ends up in the sea. Such plastic waste

High-energy Magnesium Batteries

A new version of high-energy magnesium batteries may find promising applications in wide range of electric vehicles and battery storage for renewable energy systems, according to researchers at University of Houston (UH) and the Toyota Research Institute of America. The new high-energy magnesium batteries, detailed in the recent issue of journal Joule, has been reported to use an organic electrode, while operating with limited electrolytes. The researchers said that such
