Tailor-Making Nano Insulation Materials with Lowered Thermal Conductivity by Utilizing the Knudsen Effect

Jelle B.P., Mofid S.A., Grandcolas M., Norwegian University of Science and Technology (NTNU), NO

As the world is turning its focus even more towards aspects like energy efficiency and renewable and non-polluting energy harvesting, including the building sector, the quest has been set for developing high-performance thermal insulation materials [...]

Monte Carlo simulation of the energetics and thermodynamics of polypyrrole in condensed phases

Helmick G., Abere Y., Blaisten-Barojas E., George Mason University, US

Polypyrrole (PPy) is a conducting polymer with a wide range of applications such as supercapacitors, sensors, batteries, actuators, and neural prosthetics. PPy is a popular polymer in experimentation not so easily accessed in computational modeling [...]

Study of Nonclassical Fullerenes C_192 and C_204 with Seven Heptagon Rings

Sanchez-Bernabe F.J., Universidad Autónoma Metropolitana, MX

In this paper, we present some examples of nonclassical fullerenes with seven heptagon rings. For instance, a nonclassical fullerene with 192 carbons, seven heptagons, 19 pentagons, and 72 hexagons, is considered. Two of the seven [...]

Distinctive thermoresponsive behavior of smart polymers solvated in glycerol from Molecular Dynamics

Hopkins S.D., Blaisten-Barojas E., George Mason University, US

Thermoresponsive polymers have been utilized in a broad range of medical and industrial applications as smart materials, including controlled drug delivery, and water treatment and desalination. While the behavior of such polymers has been modeled [...]

Delocalized Electron Relay in Superconductive Multiple-layer Self-Assembled Membranes Promoted Room-temperature d Wave Mixed-spin Triplet of Copper-pair to Penetrate Toroidal Josephson Junction Barriers with a Magnitude Higher Open Circuit Potential

Chen E.T., Thornton J.T., Duh S-H, Advanced Biomimetic Sensors, Inc., US

A room temperature superconductive/mem-element device is developed, and it comprises (1) superconductive - insulator-superconductive (SIS) structure, (2) immobilized zinc ions in the self-assembled membrane (SAM) promoted d wave mixed-spin triplet bounding enhanced curvature nanotubes formations [...]

Adhesive Offering Z-Axis Conductivity, Stretchability and Manufacturing Scalability for LED Electroactive Light Sheets

Stemmermann A., Stemmermann M., Balder D., Stemmermann A., Stemmermann M., Lall P., SunRay Scientific LLC, US

New product demands call for new solutions. Globally, the electrically conductive adhesives market has seen more than 40 new product launches in the last three years. Clearly certain needs are as yet unmet. Among those [...]

Malekmohammadi A., Bautista R.R., Hernandez R., California state university Bakersfield, US

COVID-19 is a pandemic that has put countries in a global crisis. In the United states over 78 Million people are infected, and more than 900 thousand deaths are reported as on February 18, 2022. [...]

Development, Manufacturing, and Application of Photoacoustic Test Phantom

Christie L.B., Schneider P.J., Heidrich J.R., Oh K.W., University at Buffalo, US

Photoacoustic (PA) research is an up and coming field that is being applied to the medical space. PA combines the use of both optics and acoustics to create a final outputted signal (Figure 1). The [...]

Computational Modeling of a Wearable Device with Feedback to Advance the Healing of Chronic Skin Ulcers

Heidrich J., Oh K.W., University at Buffalo, US

This paper discusses how COMSOL Multiphysics modeling software allows for design ideas to be validated through computer simulation. The simulations generated show the Organic Electrochemical Field Effect Transistor (OECT) with a Poly(imide) (PI) polymer microfluidic [...]

COGMCI – Toward a Zero CO2 Economy

Boschiero do Espirito Santo D., Sisterm Thermal Systems, BR

Intermittent electricity (solar and wind) needs to be equilibrated with resilient supply. Fuel demand can be partially replaced by electric cars, heat pumps, and electrical equipment. How much additional electricity will be required? How much [...]
