Flexible Microfluidics-Integrated Organic Transistor as Biofeedback for Advanced Wound Healing

Heidrich J., Oh K.W., The State University of New York at Buffalo, US

This paper will discuss how incorporating a biofeedback sensor into an electrical stimulation bandage used on chronic ulcers will improve the healing process. Current wound healing devices, and specifically wearable ones, are an open loop [...]

HTL Derived Biochar for Supercapacitor Electrodes

Amar V.S., Houck J.D., Huynh K., Maddipudi B.K., Shende R.V., South Dakota School of Mines and Technology, US

In this study, biochar samples were prepared by conversion of biomass feedstock (corn stover) via catalytic hydrothermal liquefaction (HTL) and later used as electrode material in conjunction with sol-gel derived perovskite based mixed (Mn,Ti)-oxides (Mn:Ti [...]

So, You’ve Set Sustainability Goals, Now What? The Growing While Shrinking Paradox

Gebolys G., Murray N., Trunfio E., World Energy, US

Climate change has emerged as the world’s greatest challenge,and pressure is coming from multiple angles for companies to reduce their carbon impact. The integrity of today’s brands is on the line, leaving businesses with the [...]

Establishing rubber dandelions and guayule in the United States via premium markets to secure essential supplies

Cornish. J. Cardina K., Fresnedo J., Michel_Jr. F.C., The Ohio State University, US

Natural rubber and latex are imported, critical, agricultural raw materials essential to all sectors of the US economy and cannot be replaced by unsustainable petroleum-derived synthetic rubbers due to their performance deficiencies. National security is [...]

The Coupling of COVID-19 Respiratory Droplet Adsorption and Photocatalysis through Metal Organic Frameworks

Ackerman D., Boehme A., Herrera V., Nouar F., Ornstein J., Ozdemir R., Santarpia J., Serre C., framergy, Inc, US

As the world recovers from the lockdown imposed by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS- CoV-2) pandemic, returning to shared indoor spaces is still considered risky. It is now clear that transmission of [...]

Fast COVID-19 diagnosis with deep learning and chest X-rays: from toy datasets to clinical applications

Dias S.D., Lopes P.E.M., FastCompChem, Lda, PT

Accurate diagnosis of COVID-19 infection is a crucial tool to identify and control the spread of the disease. Current frontline technology, based on Reverse Transcription Polymerase Chain Reaction (RT-PCR), can depend on getting an adequate [...]

Kidney Cancer Staging using Deep Learning Neural Network: Comparing Models Trained on Whole Kidney with Cancer and Only the Cancer

Hadjiyski N., Ann Arbor Pioneer High School, US

In kidney cancer, Stage 1 is an important threshold for the decision of organ preservation surgery versus chemotherapy and organ removal for higher stages. The purpose of this study is to compare the classification accuracy [...]

Roboplasmid: A remotely programmable plasmid for rapid viral inactivation

Jayarapu K., Kalra A., Carmel High School, US

For eons, humankind has been plagued by viral infections that have decimated populations; we lack a system that can simply inactivate any virus at will. Here we describe a model for a non-nucleotide-based, robotic plasmid [...]

Gelation Behavior Study of Thermogelling Poly(ε-Caprolactone-co-1, 4, 8-Trioxa[4, 6]Spiro-9- Undecanone)-Poly(Ethylene Glycol)-Poly(ε-Caprolactone-co-1, 4, 8- Trioxa[4, 6]Spiro-9-Undecanone)

Chen T.Y., Wang X-Y, Wang Z.F., Zhong S., Zhuang T.T., ABB US Corporate Research Center, US

PEG-PCT) has been successfully synthesized via ring opening polymerization. By adjusting initial monomer feeding ratio, TOSUO molar content in the hydrophobic block increases from 0% to 20% while the repeat units of the blocks remain [...]

Focused Transcranial Magnetic Stimulation

Baron M., Carmona I., Hadimani R.L., Kumbhare D., Virginia Commonwealth University, US

Transcranial Magnetic Stimulation is a non-invasive technique used to regulate the synaptic activity of neurons, improving the functionality of several regions and bringing effective treatment to neurological and psychiatric disorders applying external time-varying magnetic fields [...]
