Enhanced Radiation Shielding with Conformal Light-weight Nanoparticle-polymer Composite

INV-19025 Background The efficient shielding of ionizing X-ray and gamma radiation is required in medical, nuclear and aerospace industries. High Z elements such as lead, tungsten, bismuth and uranium are often used to attenuate X-ray radiation, where the shielding ability is dependent on the density and mass of the material, leading to heavy shielding...

High throughput toxicity assay on coordinately ordered single cells with individual identity

INV-18104 Background Cytotoxicity plays an important role in understanding biological mechanisms, detecting diseases, and screening therapeutics. Cytotoxicity measurement is usually carried out by incubating cells in different sized wells with a specific treatment, which yields results based on the average response of cells in the same well. However,...

A Programmable Digitally Controlled Point-of-Load DC-DC Buck Converter Suitable for Space Applications

Buck converters are essential to modern electronics as they can maintain an output voltage at a desired range. Two of the main methods to accomplish this are hysteretic control and pulse width modulation (PWM). Hysteretic controllers continually monitor the output voltage and adjust it if it is too high or too low, but have bad frequency control. On...
