Air Pollution Mitigation Technology

Chaganti V., Cheruvu M., Akshara Yantra, US

Particulate Matter (PM2.5 and PM10), and Greenhouse gases contribute to major pollution and climate change. Worldwide governments are implementing changes to cutdown the pollution producing sources and greenhouse gases. Can this change take place completely [...]

Effect of Biochar Loading on Carbon Nanofibrous Sponge Produced from Biochar and Electrospun Polymer Nanofibers

Numan-Al-Mobin A.M., Maddipudi B., Amar V.S., Shende R.V., Fong H., South Dakota School of Mines and Technology, US

The goal of this study is to process a typical waste product, namely the biochar obtained from the oxygen-limited hydrothermal system of biomass (e.g., corn stover), into the value-added product. Particularly, the 3D carbon nanofibrous [...]

Liquid core nanocapsules synthesized using flash nanoprecipitation

Van Keuren E., Taylor S., Chung Y., Chen L., Ugwu-Uche U., Aparicio V.A., Meehan R., Hughes E., Georgetown University, US

The synthesis and application of multicomponent and/or multifunctional nanoparticles is an area that has seen significant growth over the past decade. Nanocapsules, nanoparticles with a liquid core and hard shell, are one example. They have [...]

Memristor Nano Memory Passive Power Device

Christensen G., Hong H., Younes H., Bailey C., Novum Nano, US

A non-volatile memory circuit that has one or more of the following features was created and patented : (a) a logic source, and (b) a semi-conductive device being electrically coupled to the logic source, having [...]

Grooved Bottom electrode Based Molecular Spintronics Device

Tyagi P., University of the District of Columbia, US

Mass fabrication of molecular spintronics devices (MSDs) can harness the untapped exotic properties of variable spin state molecules for making the next generation of computers, including quantum computers. However, since the conceptualization of molecular devices [...]

Increasing Engine Efficiency with Friction Reducing-Oil Additives

Christensen G., Grablander T., Bailey C., Lou D., Hong H., Novum Nano, US

Typical engine oils used in internal combustion gas and diesel engines are not high in thermal conductivity and are limited in friction performance, which together limit engine efficiency and longevity. Carbon nanotubes and hexagonal boron [...]

Accurate Pole Testing Can Increase Resilience of Power Supply Grid and Save Billions of Dollars at the Same Time

Deuar K., Kris Deuar & Associates, Inc., US

Resilience of power supply grid can be increased substantially by more accurate pole inspection and testing. Electric utilities are unnecessarily replacing or re-enforcing electrical poles that still have many years of useful life. Our proof [...]

3D printed energy efficient magnetocaloric cooling devices with controlled microchannels, functional grading and magnetic anisotropy

Sharma V., Balderson L., Barua R., Zhao H., Hadimani R.L., Virginia Commonwealth University, US

Air conditioning and refrigeration are regarded as one of the most energy-intensive technologies in demand today. Currently, 15% of the world's electric power is devoted to cooling, with that value increasing to 20% in the [...]

Cost Effective Mitigation of Wildfire Risk Generated by Power Lines

Deuar K., Kris Deuar & Associates, Inc., US

The recently developed extremely accurate Micro- Stress Pole Testing (MSPT) technology can save a lot of money by elimination of costly replacements of poles which are prematurely rejected by presently used inaccurate pole inspection methods. [...]

Exploring the Role of Nanomaterials in Advancing Solar Thermal Technologies

Demirel O., Bond A., Beachnau B., Anderson M.G., Icarus RT, Inc., US

Photovoltaics (PV) are a viable renewable energy technology, yet inadequate conversion efficiency remains a steadfast problem. A heat extractor that will attach to the back of a PV panel will cool it and boost its [...]
