Spectral-Splitting Optical Systems and Devices

The greatest source of loss in conventional single-junction photovoltaic cells is their inefficient utilization of the energy contained in the full spectrum of sunlight. To overcome this deficiency, UC researchers have validated a multijunction system that laterally splits the solar spectrum onto a planar array of single-junction cells with different band gaps. They have demonstrated dispersive diffractive optics that spatially separated visible (360–760 nm) and near-infrared (760–1100 nm) bands of sunlight in the far field. Their optimized thin film fabricated by femtosecond two-photon absorption 3D direct laser writing showed on average a splitting ratio of about 70% between the visible and near-infrared light over the 380–970 nm range at normal incidence, and with the splitting efficiency predicted >80% assuming a structure without fabrication errors. The spectral-splitting action was observed within an angular range of ±1° from normal incidence. Further design optimization and fabrication improvements could increase the splitting efficiency under direct sunlight, increase the tolerance to angular errors, allow for a more compact geometry, and ultimately incorporate a greater number of photovoltaic band gaps.

Mi-181: A Potent Small Synthetic Microtubule-Targeting Anticancer Agent

UCLA researchers in the Department of Chemistry & Biochemistry and Department of Molecular & Medical Pharmacology have discovered compound MI-181 and successfully synthesized its derivatives and analogs, which have the potential for use in cancer therapy by arresting cells during the process of cell division and promoting apoptosis.

Shaped Piezoelectric Micromachined Ultrasonic Transducer Device

Piezoelectric Micromachined Ultrasonic Transducers (pMUTs) have attracted industry attention for their good acoustic matching, small geometry, low cost-by-batch fabrication, and compatibilities with CMOS and consumer electronics. While planar pMUTs have reasonable performance over bulk piezoelectric transducers, certain deficits remain in terms of coupling and acoustic pressure outputs, DC displacements, bandwidth, and power consumption. To address these deficiencies, researchers at the University of California, Berkeley, have developed a next generation of shaped pMUTs which are no longer fully defined by resonance frequency and can accommodate larger pressure outputs and bandwidths. This new pMUT apparatus can significantly boost overall performance while dramatically reducing power as compared to flat diaphragm state-of-the-art pMUTs.

Electronically controllable laser and point location system for body worn laser therapeutic systems

Photonic physiological and neurological stimulation is the application of therapeutic lasers to classical acupuncture points on the body for therapeutic purposes. The therapy is typically delivered with a manually held and adjusted laser, which can be inexact and unsteady. Working together, inventors at UCI and Samueli Institute have developed a computer-controlled photonic stimulation system that is capable of using complex therapy protocols to provide more effective treatment using multiple laser sources.

Self-Adaptive Control And Optimization Of Ultrafiltration

UCLA researchers in the Department of Chemical and Biomolecular engineering have developed a novel UF-RO system.

Therapeutic strategies for Huntington’s Disease using stop codon suppression

In Huntington’s Disease (HD), aberrant splicing of the huntingtin protein can produce a highly toxic peptide that accumulates in the brain. The invention describes methods to minimize the toxicity of spliced proteins.

Antibodies targeting mammalian Sterol Regulatory Element Binding Proteins (SREBP) 1 and 2

Sterol Regulatory Element Binding Proteins (SREBP) are important factors that control lipid homeostasis in mammals. Researchers at UCI have prepared antibodies that have good affinity and specificity for human SREBP1/2 for use as research tools. These antibodies have application in genetic and immunotherapeutic research areas.

Method and apparatus for three-dimensional imaging of molecular bonds

Researchers at UCI have developed a 3D imaging technique with sub-nanometer resolution, which allows for imaging of individual bonds within molecules. Visualization and measurements taken at this resolution provide new and profound information about the fundamental aspects of atomic structures and their consequences on chemical activity.
