Cleaning Lithium to Improve Protective Layer

Professor Dunn and colleagues have developed a method to improve the homogeneity of a protective layer placed upon a lithium metal surface. By removing surface impurities from the lithium and applying a uniform protective layer, a more homogenous current distribution can be maintained across the electrode and dendrite formation can be suppressed. 

Method and System for High Recovery Water Desalting

Professor Cohen and colleagues have developed a method and system to continuously, sustainably, and inexpensively desalinate high salinity water of high mineral scaling propensity. The system is able to process waters as contaminated as industrial, agricultural, and mining wastewaters, with recovery levels reach in excess of 90-95%.

Thermal Mechanical Energy Harvesting

An inventive energy harvesting apparatus may include a ferromagnetic material and/or a shape memory alloys to convert thermal energy to mechanical energy to electrical energy. The apparatus is subjected to a thermal gradient to cause beams to bend thus creating stress/strain in a piezoelectric material, or creating magnetic flux in a magnetic path. The charges created in this process can be transferred to electrical batteries.

Fouling and Scaling Resistant Surface Nano-Structured Membranes

Professor Cohen and his research team have developed a novel class of membranes capable of resisting organic- and biofouling, as well as mineral salt scaling. These novel membranes have applications in water treatment and desalination, where biomaterial buildup and salt scaling of reverse osmosis membranes represent major impediments to high recovery rates.

Inorganic Admixtures for Preventing Conversion Phenomena in High-Alumina Cements

Professor Sant and colleagues have developed a method to prevent the strength loss caused by increased porosity seen in high alumina cement systems. The addition of inorganic admixtures serves to suppress hydrogarnet formation at the expense of more stable AFm phases. The result is high-alumina cement with increased volume stability and corrosion resistance.

Flexible Nanotube Transistors

Professor Grüner and colleagues have developed films of nanostructures that can be integrated into flexible semiconducting substrates. This technology has applications in flexible displays, wearable electronics, intelligent paper, and other lightweight, low-cost electronics. 

Nanostructured Polymer Electrodes

Professor Kaner and colleagues at UCLA and Caltech have developed novel electrode structures for use in the storage of ions made with novel nanostructured polymer films. This technology takes advantage of a new class of nanofiber conjugate polymer materials to form amphoteric electrodes that demonstrate improved cycling properties and remarkable application flexibility.

Integrated Ultrafiltration and Reverse Osmosis Process and System

Professor Cohen and colleagues have developed a compact and self-adaptive integrated water ultrafiltration and reverse osmosis (UF/RO) process and system. Designed to produce up to 18,000 gallons of drinking quality water per day with no intermediate tanks between UF and RO or for UF backwash, the system can be further expanded for even larger capacity. In addition, the system is remotely monitored and is self-adaptive, making use of advanced model-based control.

Polyaniline Nanofiber Composite Materials: New Chemical Sensors for Phosgene

Professor Kaner and colleagues have developed a sensor with polyaniline polymers for the detection of phosgene (COCl2), a colorless, highly toxic gas that has been used in chemical warfare as well as in industrial processes for polyurethanes. The approach provides a sensitive (ppb) method to detecting this highly poisonous gas.

UCLA scientists have developed a tabletop system capable of generating small-scale nuclear fusion.

Polyanaline Nanofibers as Hydrogen Sensors

Professor Kaner and colleagues have developed a method for sensing hydrogen using polyaniline nanofiber material. The approach utilizes detectable conductivity changes in the nanofiber material when exposed to hydrogen gas. This polyaniline sensor has advantages over traditional palladium-based sensors in that its phase change for detection is reversible and its synthesis is inexpensive.  

Multiple Donor/Acceptor Bulk Heterojunction Solar Cells

Professor Yang and colleagues have developed a new device structure for organic photovoltaics that expands the absorption bandwidth and increases overall device performance of the organic solar cells. In contrast to multiple junction solar cells, the approach does not require further fabrication steps, thereby mitigating increases in manufacturing cost and complexity.        

Conjugated Polymers with Selenium Substituted Diketopyrrolopyrrole Unit for Electronics Devices

Organic photovoltaic devices provide an opportunity to utilize solar energy efficiently and at low cost. To harvest a greater spectrum of light, scientists have sought to reduce the energy bandgap of the active material. UCLA researchers have developed a novel low-bandgap polymer that provides excellent photovoltaic performance in single junction devices (PCE >7%). This technology has application to organic solar cells, tandem solar cells, transparent solar cells, field-effect transistors, near infrared (NIR) organic photo-detectors, and NIR organic light emitting diodes, among others.

Researchers at UCLA have developed a low-cost thin-film solar cell fabrication method by replacing vacuum-based deposition with a spray-coating solution-based deposition technique that produces dense films, while avoiding film cracking and the edge-effect.
