Wireless Energy Harvesting and Storage
PAGE TITLEOverviewPAGE SUMMARY Energy storing and harvesting textiles are currently being developed at Drexel University. Antennas are tuned to harvest or scavenge energy at 2.4 GHz from the WiFi frequency band. The antenna is fully knitted from conductive yarns on industrial knitting machines. The antenna is connected to a small circuit that can collect...

Low-cost manufacturing of highly sensitive label-free molecular detection substrates
PAGE TITLE Overview PAGE SUMMARY Label-free detection and characterization of molecules is an important tool for detecting a composition of a substance, be it a water, soil, chemical product or biological sample. Its main advantage is the ability to measure quantities of different molecules without knowing their identity in advance. Examples...

Fibrous Mats Containing Chitosan Nanofibers
PAGE TITLEOverviewPAGE SUMMARY Electrolytes such as sodium play an important role in maintaining homeostasis within the body. Sweat is the visible manifestation of a body’s attempt to correct electrolytic imbalances due to changes in hydration state. However, the appearance of dampness on clothing is insufficient to assess homeostasis because...

Infinite-dimensional integrated digital image correlation (IDIC)
Background Digital image correlation (DIC) methods are common in laboratory experi­ments. Often termed two-dimensional digital image correlation (2D-DIC), the method uses a camera to acquire images of a planar object that is deforming nominally within the specimen surface plane that is being imaged. DIC algorithms typically perform the image registration...

Rare earth metal extraction from ash
Background Rare earth elements (REEs), such as lanthanides, yttrium, and scandium, are critical components in numerous advanced technologies, including electronics, energy storage systems, and medicine. Currently, the majority of REEs are sourced from a limited number of mining operations, which poses substantial risks to geopolitical tensions, supply...

Negative enthalpy collector coatings to enhance stability of metal anodes
Problem Anodeless or anode-free liquid, solid and hybrid liquid-solid batteries hold tremendous promise, offering lower cost in parallel to over 50% higher energy by weight and by volume. However, because of the poor Coulombic efficiency (CE)—which leads to poor cathode utilization, rapid capacity fade during cycling, an unstable solid electrolyte...

Functionalized kapok fiber filter for oil and bacteria removal
Problem statement Contaminated water from the produced water industry must be treated prior to discharge, reuse, or recycling. Advanced treatment is often necessary to meet increasingly strict regulations, leading to membrane filtration use in produced water treatment. These membranes are susceptible to different forms of fouling, especially when organics...
