At-Nozzle Injection of Agrochemicals

Researchers at the University of California, Davis have developed a direct, at-nozzle system for directly mixing and dispensing a carrier fluid with additives.

Novel Sensor to Transduce and Digitalize Temperature Utilizing Near-Zero-Power Levels

Temperature sensors are routinely found in devices used to monitor the environment, the human body, industrial equipment, and beyond. In many such applications, the energy available from batteries or the power available from energy harvesters is extremely limited, thus the power consumption of sensing should be minimized in order to maximize operational lifetime.

Novel Anti-Bacterial, Anti-Fungal Nanopillared Surface

Medical devices are susceptible to contamination by harmful microbes, such as bacteria and fungi, which form biofilms on device surfaces. These biofilms are often resistant to antibiotics and other current treatments, resulting in over 2 million people per year suffering from diseases related to these contaminating microbes. Death rates for many of these diseases are high, often exceeding 50%. Researchers at UCI have developed a novel anti-bacterial and anti-fungal biocomposite that incorporates a nanopillared surface structure that can be applied as a coating to medical devices.

Advanced Chemical Sensing Method and Apparatus

Conventional chemical sensors or chemical resistors detect the molecule concentration by monitoring the resistance change caused by the reaction near the sensing material surface. One of the problems with these systems is with drift, when over time the analyte molecules poison the device’s sensing surface, causing weaker performance on selectivity and sensitivity. This often requires rigorous and timely calibrations to the sensor, which involves human intervention, and often times complete sensor replacement. To address this problem, researchers at the University of California, Berkeley, have developed a vertical platform that dramatically improves the sensor’s ability to manage and recover from the poison environments. By examining and manipulating the sensing plane vis-à-vis the near field surface, researchers have demonstrated an effective and robust chemical sensing platform for a range of gas sensing applications.

Soft-tissue injuries and organ transplantation are common in modern combat scenarios.

Micro and nanobubbles (MNBs) offer a new technology that could supply oxygenation to such tissues prior to transplantation, thus affording better recovery and survival of patients. Described here is a novel device capable of producing MNB solutions that can be used to preserve viability and function of such organs/tissue. Additionally, these solutions may be used with negative pressure wound therapy to heal soft-tissue wounds.
