Long-lived photoinduced charge separation for solar cell applications in supramolecular complexes of multi-metalloporphyrins and fullerenes (2013)

Monomers, dimers, trimers, dendrimers and oligomers of metalloporphyrins form supramolecular complexes with fullerene derivatives via electrostatic interactions, π–π interactions and coordination bonds. Photoexcitation of the supramolecular complexes resulted in photoinduced electron transfer from the porphyrin moiety to the fullerene moiety to produce the charge-separated states as revealed by laser flash photolysis measurements. The rate constants of photoinduced charge separation and charge recombination in supramolecular complexes of multi-metalloporphyrins and fullerenes were also determined by laser flash photolysis measurements and the results depending on the number of porphyrins in the supramolecular complexes are discussed in terms of efficiency of photoinduced energy transfer and charge separation as well as the lifetimes of charge-separated states. The photoelectrochemical performances of solar cells composed of supramolecular complexes of monomers, dimers, dendrimers and oligomers of metalloporphyrins with fullerenes are compared in relation to the rate constants of photoinduced charge separation and charge recombination.
Focused injection of vacuum arc plasmas into curved magnetic filters (1994)

Thin films of high quality can be deposited using vacuum arc plasmas when the macroparticles which are produced along with the plasma in the cathode spots are removed by curved magnetic filters (‘‘ducts’’). In order to improve the deposition efficiency of a vacuum arc plasma source coupled to a magnetic filter, the effect of a magnetically focused plasma injection into such a filter has been investigated. Maximum plasma output was found at an optimum focusing field strength of 20–40 mT with an optimum duct bias of +20 V with respect to the anode potential (ground potential). The maximum output is by a factor of 20–30 greater than without focusing field and the duct at ground potential. This significant effect at relatively low injection field strength indicates that not only the magnetic field distribution but also the plasma current distribution is essential for an efficient plasma transport.
Micro-machined optical add/drop multiplexer with client configurability (2002)

The rapid evolving of optical transport systems into WDM systems has shown clear demands for functionalities inside the optical layer to manipulate the traffic on the wavelength basis. One such important functionality is to use optical add/drop multiplexers (OADM) to add and drop a subset of wavelengths from the transmission system without full opto-electronic regeneration. OADMs play important roles both in optical core networks and in regional access networks. In this paper we demonstrate a client configurable OADM using a 8/spl times/6 micro-machined matrix switch, and propose several OADM architectures to achieve client-configurability in different network environments.
Feasibility of in hive control of adult small hive beetles 'Aethina tumida' Murray (Coleoptera: Nitidulidae) with an insecticide treated refuge trap (2008)

The significant impact of small hive beetle on the profitability of bee keeping in eastern Australia prompted research into the use of insecticidal traps for deployment in beetle infested hives. A prototype refuge trap comprising foil-covered fiproniltreated corrugated cardboard achieved up to 100% control of adult beetles in field efficacy trials conducted in western Sydney apiaries. Although demonstrating the feasibility of using such a refuge trap against beetle infestations damage to some traps by resident bees and resultant bee deaths highlighted the need for a more robust cover for the insecticide-treated cardboard insert.
Fabrication of out-of-plane SU-8 refractive microlens using direct lithography method (2004)

To develop an integrated optical bench or free-space optical system, a focusing lens’ optical axis is required to be parallel with the substrate on which the whole system is located. In micro-optical systems, hinged lenses were fabricated in surface technologies and suspended with a mechanical hinge, then driven up to the required vertical position using electrostatic or electromagnetic actuation. In this paper, we report the research work to design, simulate, and fabricate a new type of microlens using direct lithograph of SU-8 resist. Without any assembly process, this microlens’ optical axis is parallel with the substrate on which the whole optical system is. The lenses obtained this way are perpendicular to the substrate and can be pre-aligned with other micro optical components. The focus of the lens can be controlled with different surface curvature by using different cylindrical beams, expose dosage, and development time. A numerical simulation is done about the SU-8 development. The optical simulation is also being done with ZEMAX software. At the same time, the optical properties of the cured SU-8 and the optical properties of this cured-SU-8 refractive microlens are also being tested and presented in this symposium.
The development and implementation of a flying height tester calibration standard (1994)

A wedge standard is developed for the correlation measurement and calibration of intensity interferometric flying height testers. This standard provides self-intensity measurement capability, eliminates material effect, covers any desired flying height range, and is stable and easy to perform calibration. It is implemented on a polychromatic interferometric flying height tester, and the calibration results are presented and discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Eis-Based in-Situ Sensor for the Early Detection of Coatings Degradation and Substrate Corrosion (2000)

Abstract An in-situ corrosion sensor has been developed that allows early detection of coating degradation and substrate corrosion. The sensor is based on electrochemical impedance spectroscopy (EIS) and extends the use of this established laboratory technique to ambient environments and field applications. The sensor directly detects degradation of the structure or specimen of interest, as opposed to degradation of a sensor component. It has applicability both to field inspection and condition-based maintenance and to coating screening and development. A permanent, painted version is suited for inaccessible areas of structures or areas/specimens for which one wishes to take repeated measurements over time, such as a panel in an accelerated test chamber or a hidden area of an aircraft. A hand-held version is suited for spot inspection or if a permanent sensor is not desired for ascetics, aerodynamics, or other reasons. Both sensors utilize commercial potentiostats for data acquisition and analysis. The sensors are able to detect and quantify moisture absorption by a coating and the early stages of degradation well before any visual indication of deterioration. The sensor measurements have been shown to predict the amount of corrosion at the end of accelerated tests that have been correlated with service performance. They have also been used to evaluate coating systems and inspect structures in the field.
Real‐time object detection using power spectral density of ground‐penetrating radar data (2019)

A statistical analytical monitoring scheme is developed that utilizes maximum energy of ground-penetrating radar signals to detect hidden buried objects and estimate their location and depth automatically. The maximum energy is calculated for locations by Welch's power spectral density estimation. Using the proposed analytic, the maximum energy is tightly monitored for a significant change from reference signals generated using target-free locations. A warning message is triggered when monitoring process detects a site with potential buried objects, on average, 90 cm (2.95 ft) away from the object for 800-MHz antenna. Continuing the ground-penetrating radar scan in the same direction and monitoring the signals, the procedure uses a sophisticated hyperbola-mapping method to estimate the location and depth of buried objects with high accuracy. The analytics could successfully pinpoint the location and depth of hidden objects, respectively, with mean absolute error of 0.38 and 2.03 cm in synthetic noisy environments. Reliable performance of the proposed analytics in real cases that run in real-time for multiple object detection even in noisy media proves its efficiency for real-life exploration.
Glucoamylase immobilized on acid‐hydrolyzed starch graft polyacrylonitrile (1988)

A continuous stirred reactor fed maltose as substrate was used to show that acid hydrolyzed starch-g-polyacry-lonitrile and other polysaccharide graft copolymers can bind and retain significant quantities of active glucoamy-lase. Glucose productivities up to 2.7 g/g carrier/h were observed with the immobilized glucoamylase, and half-lives up to 1800 h were indicative of activity longevity. Factors influencing the immobilized enzyme activity and first-order decay rate included temperature, p(H), and carrier composition. In all cases, maltose was converted quantitatively to glucose with no evidence of reversion product formation.
Gene Alterations Identified by Expression Profiling in Tumor-Associated Endothelial Cells from Invasive Ovarian Carcinoma (2007)

Therapeutic strategies based on antiangiogenic approaches are beginning to show great promise in clinical studies. However, full realization of these approaches requires identification of key differences in gene expression between endothelial cells from tumors versus their normal counterparts. Here, we examined gene expression differences in purified endothelial cells from 10 invasive epithelial ovarian cancers and 5 normal ovaries using Affymetrix U133 Plus 2.0 microarrays. More than 400 differentially expressed genes were identified in tumor-associated endothelial cells. We selected and validated 23 genes that were overexpressed by 3.6- to 168-fold using real-time reverse transcription-PCR and/or immunohistochemistry. Among these, the polycomb group protein enhancer of Zeste homologue 2 (EZH2), the Notch ligand Jagged1, and PTK2 were elevated 3- to 4.3-fold in tumor-associated endothelial cells. Silencing these genes individually with small interfering RNA blocked endothelial cell migration and tube formation in vitro. The present study shows that tumor and normal endothelium differ at the molecular level, which may have significant implications for the development of antiangiogenic therapies.

Wide-view transflective liquid crystal display for mobile applications (2007)

A high optical efficiency and wide-view transflective liquid crystal display based on fringe-field switching structure is proposed. The transmissive part has a homogenous liquid crystal (LC) alignment and is driven by a fringe electric field, which exhibits excellent electro-optic characteristics. The reflective part has a hybrid LC alignment with quarter-wave phase retardation and is also driven by a fringe electric field. Consequently, the transmissive and reflective parts have similar gamma curves.
Topical interferon alpha 2b for corneal haze after excimer laser photorefractive keratectomy (1996)

Topical IFN-alpha may merit further investigation as a treatment to reduce corneal haze after excimer laser PRK for corrections greater than 5.00 D.
A new wafer-level packaging technology for MEMS with hermetic micro-environment (2011)

We report a new wafer-level packaging technology for miniature MEMS in a hermetic micro-environment. The unique and new feature of this technology is that it only uses low cost wafer-level processes such as eutectic bonding, Bosch etching and mechanical lapping and thinning steps as compared to more expensive process steps that will be required in other alternative wafer-level technologies involving thru-silicon vias or membrane lids. We have demonstrated this technology by packaging silicon-based AlN microsensors in packages of size 1.3 × 1.3 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and 200 micrometer thick. Our initial cost analysis has shown that when mass produced with high yields, this device will cost $0.10 to $0.90. The technology involves first preparing the lid and MEMS wafers separately with the sealring metal stack of Ti/Pt/Au on the MEMS wafers and Ti/Pt/Au/Ge/Au on the lid wafers. On the MEMS wafers, the Signal/Power/Ground interconnections to the wire-bond pads are isolated from the sealring metallization by an insulating AlN layer. Prior to bonding, the lid wafers were Bosch-etched in the wirebond pad area by 120 um and in the center hermetic device cavity area by 20 um. The MEMS and the lid wafers were then aligned and bonded in vacuum or in a nitrogen environment at or above the Au-Ge Eutectic temperature, 363°C. The bonded wafers were then thinned and polished first on the MEMS side and then on the lid side. The MEMS side was thinned to 100 ums with a nearly scratch-free and crack-free surface. The lid side was similarly thinned to 100 ums exposing the wire-bond pads. After thinning, a 100 um thick lid remained over the MEMS features providing a 20 um high hermetic micro-environment. Thinned MEMS/Lid wafer-level assemblies were then sawed into individual devices. These devices can be integrated into the next-level assembly either by wire-bonding or by surface mounting. The wafer-level packaging approach developed in this project demonstrated RF Feedthroughs with <;0.3 dB insertion loss and adequate RF performance through 2 GHz. Pressure monitoring Pirani structures built inside the hermetic lids have demonstrated the ability to detect leaks in the package. In our preliminary development experiments, we have demonstrated >;50% hermetic yields.
Sugarcane genes associated with sucrose content (2009)

Gene expression analysis of sugarcane populations contrasting for sucrose content indicated a possible overlap with drought and cell wall metabolism processes and suggested signaling and transcriptional regulators to be used as molecular markers in breeding programs. Transgenic research is necessary to further clarify the role of the genes and define targets useful for sugarcane improvement programs based on transgenic plants.
A system for automated mapping of bill-of-materials part numbers (2004)

Part numbers are widely used within an enterprise throughout the manufacturing process. The point of entry of such part numbers into this process is normally via a Bill of Materials, or BOM, sent by a contact manufacturer or supplier. Each line of the BOM provides information about one part such as the supplier part number, the BOM receiver's corresponding internal part number, an unstructured textual part description, the supplier name, etc. However, in a substantial number of cases, the BOM receiver's internal part number is absent. Hence, before this part can be incorporated into the receiver's manufacturing process, it has to be mapped to an internal part (of the BOM receiver) based on the information of the part in the BOM. Historically, this mapping process has been done manually which is a highly time-consuming, labor intensive and error-prone process. This paper describes a system for automating the mapping of BOM part numbers. The system uses a two step modeling and mapping approach. First, the system uses historical BOM data, receiver's part specifications data and receiver's part taxonomic data along with domain knowledge to automatically learn classification models for mapping a given BOM part description to successively lower levels of the receiver's part taxonomy to reduce the set of potential internal parts to which the BOM part could map to. Then, information about various part parameters is extracted from the BOM part description and compared to the specifications data of the potential internal parts to choose the final mapped internal part. Mappings done by the system are very accurate, and the system is currently being deployed within IBM for mapping BOMs received by the corporate procurement/manufacturing divisions.
Generation of Endosomolytic Reagents by Branching of Cell-Penetrating Peptides: Tools for the Delivery of Bioactive Compounds to Live Cells in Cis or Trans (2010)

We describe the synthesis and cellular delivery properties of multivalent and branched delivery systems consisting of cell-penetrating peptides assembled onto a peptide scaffold using native chemical ligation. A trimeric delivery system presenting three copies of the prototypical cell-penetrating peptide TAT shows an endosomolytic activity much higher than its monomeric and dimeric counterparts. This novel reagent promotes the endosomal release of macromolecules internalized into cells by endocytosis, and as a result, it can be used to achieve cytosolic delivery of bioactive but cell-impermeable macromolecules in either cis (covalent conjugation) or trans (simple coincubation).
Broad-gain (Δλ/λ_0~04), temperature-insensitive (T_0~510K) quantum cascade lasers (2011)

Broad-gain operation of λ~8.7 μm quantum cascade lasers based on dual-upper-state to multiple-lower-state transition design is reported. The devices exhibit surprisingly wide (~500 cm(-1)) electroluminescence spectra which are very insensitive to voltage and temperature changes above room temperature. With recourse to the temperature-insensitivity of electroluminescence spectra, the lasers demonstrate an extremely-weak temperature-dependence of laser performances: T0-value of 510 K, associated with a room temperature threshold current density of 2.6 kA/cm2. In addition, despite such wide gain spectra, room temperature, continuous wave operation of the laser with buried hetero structure is achieved.
Arabidopsis Novel Glycine-Rich Plasma Membrane PSS1 Protein Enhances Disease Resistance in Transgenic Soybean Plants (2017)

Nonhost resistance is defined as the immunity of a plant species to all nonadapted pathogen species. Arabidopsis (<i>Arabidopsis thaliana</i>) ecotype Columbia-0 is nonhost to the oomycete plant pathogen <i>Phytophthora sojae</i> and the fungal plant pathogen <i>Fusarium virguliforme</i> that are pathogenic to soybean (<i>Glycine max</i>). Previously, we reported generating the <i>pss1</i> mutation in the <i>pen1-1</i> genetic background as well as genetic mapping and characterization of the Arabidopsis nonhost resistance <i>Phytophthora sojae</i>-susceptible gene locus, <i>PSS1</i> In this study, we identified six candidate <i>PSS1</i> genes by comparing single-nucleotide polymorphisms of (1) the bulked DNA sample of seven F<sub>2:3</sub> families homozygous for the <i>pss1</i> allele and (2) the <i>pen1-1</i> mutant with Columbia-0. Analyses of T-DNA insertion mutants for each of these candidate <i>PSS1</i> genes identified the <i>At3g59640</i> gene encoding a glycine-rich protein as the putative <i>PSS1</i> gene. Later, complementation analysis confirmed the identity of <i>At3g59640</i> as the <i>PSS1</i> gene. <i>PSS1</i> is induced following <i>P. sojae</i> infection as well as expressed in an organ-specific manner. Coexpression analysis of the available transcriptomic data followed by reverse transcriptase-polymerase chain reaction suggested that <i>PSS1</i> is coregulated with <i>ATG8a</i> (<i>At4g21980</i>), a core gene in autophagy. PSS1 contains a predicted single membrane-spanning domain. Subcellular localization study indicated that it is an integral plasma membrane protein. Sequence analysis suggested that soybean is unlikely to contain a PSS1-like defense function. Following the introduction of <i>PSS1</i> into the soybean cultivar Williams 82, the transgenic plants exhibited enhanced resistance to <i>F. virguliforme</i>, the pathogen that causes sudden death syndrome.
Noncontact Selective Laser-Assisted Placement of Thinned Semiconductor Dice (2012)

New laser-induced forward transfer (LIFT) techniques promise to be a disruptive technology by enabling high-volume placement of ultrathin bare dice. Limitations of current die-attach techniques such as pick-and-place are presented and discussed which inspired the development of this new placement method. The thermo-mechanical selective laser-assisted die transfer (tmSLADT) process is introduced as an application of the unique blistering behavior of a dynamic releasing layer when irradiated by low-energy-focused UV laser pulses. The potential for tmSLADT to be the next generation LIFT technique is demonstrated by the “touchless” transfer of 65-μm-thick silicon tiles between two substrates spaced 195 μm apart. Additionally, the advantages of an enclosed blister actuator mechanism over previously studied ablative and thermal releasing techniques are discussed. Finally, experimental results indicate that this nonoptimized die transfer process compares with, and may exceed, the placement precision of current assembly techniques.
