Rheological Tuning of the Crystal Growth

Solutions of shear-thinning polymers are known to decrease in viscosity as a shear force is applied to the solution. In this work, the inventors show that by pre-shearing a shear-thinning polymer solution mixed with a precursor solution of a semiconducting crystal we can tune the size and morphology of the growing crystals, which governs the optoelectronic properties of the formed crystals. By pre-shearing the solution we are able to lower the viscosity of the solution, which plays a key role in the liquid phase processing (eg., coating processes). By forming a thinner, low-viscosity coating, we are able to tune the nucleation and growth rate of the crystals to form crystals that are smaller and more uniformly distributed in size, leading to a uniform and conformal coating. This approach allows us to coat a uniform layer of semiconducting crystals, which is necessary for developing functional optoelectronic devices.

Method and Apparatus for Movement Therapy Gaming System

Rehabilitation therapy, while an important tool for the long term recovery of patients affected by brain injury or disease, is expensive and requires one-on-one attention from a certified healthcare professional. UCI researchers have developed a computer-based system that provides arm movement therapy for patients. The system allows patients to independently practice hand and arm movements, improving therapeutic outcomes, while reducing hospital visits and cost for both patients and healthcare providers.

Array Atomic Force Microscopy Enabling Simultaneous Multi-point and Multi-modal Nanoscale Analyses

Nanoscale multipoint structure-function analysis is essential for deciphering the complexity of multiscale physical and biological systems. Atomic force microscopy (AFM) allows nanoscale structure-function imaging in various operating environments and can be integrated seamlessly with disparate probe-based sensing and manipulation technologies. However, conventional AFMs only permit sequential single-point analysis. Widespread adoption of array AFMs for simultaneous multi-point study is still challenging due to the intrinsic limitations of existing technological approaches.

Near-Zero Power Fully Integrated CMOS Temperature Sensor

With the planned proliferation of the Internet-of-Things, billions of power limited wireless sensing devices are expected to be sold worldwide.  Within that group is a large subset of applications in which temperature sensing will be important.  Needed for this application space are ultra-small and ultra-low-power temperature sensors. 

Low-noise Low-power ADC for Direct Biopotential Recording in Neuroscience Applications

High-density multi-channel neural recording is critical to driving advances in neuroscience and neuroengineering through increasing the spatial resolution and dynamic range of brain-machine interfaces.  Neural signal acquisition ICs have conventionally been designed composed of two distinct functional blocks per recording channel: a low-noise amplifier front-end (AFE), and an analog-digital converter (ADC).  Hybrid architectures utilizing oversampling ADCs with digital feedback have seen recent adoption due to their increased power and area efficiency. However, input dynamic range (DR) is still relatively limited due to aggressive supply voltage scaling and/or capacitive sampling noise.

Cloud- enabled Wireless pH Monitoring in Laboratory Sample Vials

A team of inventors at UCI have developed a miniaturized, wireless pH sensing system capable of monitoring the pH of laboratory samples in real-time with cloud-enabled connections for data collection. The sensor is designed to fit into the caps of standard sample vials, providing continuous measurements and eliminating the need to open vials during sensing.

Multiplex Charge Detection Mass Spectrometry

Native mass spectrometry (MS), in which electrospray ionization (ESI) is used to transfer large macromolecules and macromolecular complexes directly from solution into the gas phase, is a powerful tool in structural biology.  However, charge-state distributions of individual components in mixtures of macromolecular complexes or synthetic polymers are often unresolved making it impossible to obtain mass information directly from an ESI mass spectrum. Other conventional methods can provide accurate masses of individual ions, but often at the expense of analysis time.     Weighing ions individually with charge detection mass spectrometry (CDMS) has the advantage that fast measurements are possible depending on the accuracy and sensitivity required. However, a limitation of trapping CDMS technology is the need to weigh single ions individually in order to eliminate potential interferences between the signals of multiple ions or ion-ion interactions that can potentially interfere with these measurements. UC researchers have created multiplex charge detection mass spectroscopy, particularly for high throughput single ion analysis of large molecules and measuring the masses of large molecules, macromolecular complexes and synthetic polymers that are too large or heterogeneous for conventional mass spectrometry measurements.  The new multiplexing method makes it possible to measure the masses of many ions simultaneously.  

Source Tracking Though Spectral Matching To Mass Spec Databases

Modern metabolomics, proteomics and natural product datasets have now reached into the millions of tandem mass (MS/MS) spectra. The rapidly growing size of these datasets precludes laborious manual data interpretation of all of the data. While MS/MS spectral library search approaches match spectra in an automated fashion, the limited size of available spectral libraries limits identification rates of datasets to single digit percentages. In addition, the sharing of experimental MS/MS data between researchers is not that common. What is needed is a way to organize both identified and unidentified spectra into structurally related molecular families that is searchable.

Flavonol Profile as a Sun Exposure Assessor for Grapes

Researchers at the University of California, Davis have developed a solar radiation assessment method for grapes that uses a flavonol profile.

Cavity Atom Interferometer For Noise-Suppressed Inertial Sensing

The sensitivity of mobile atom interferometers for gravimetry, gradiometry and inertial sensing has been limited by a noise floor due to ground vibrations, as well as available free-fall space.    UC Berkeley researchers have developed an interferometer geometry that addresses both problems within an optical cavity. The utility of such a device lies primarily in its application as a mobile sensor, particularly for situations in the absence of a GPS signal (such as in deep-sea submarines, or in the event of a GPS system failure).  Similarly, sensing using gravitational signals has wide applicability. The configuration of this device accumulates an acceleration phase sensitive to low-frequency accelerations (i.e., gravity) while demonstrating an immunity to accelerations at higher frequencies than the held times (i.e., vibrations).
