Solution-deposited CIGS thin films for ultra-low-cost photovoltaics (2010)

We describe the production of photovoltaic modules with high-quality large-grain copper indium gallium selenide (CIGS) thin films obtained with the unique combination of low-cost ink-based precursors and a reactive transfer printing method. The proprietary metal-organic inks contain a variety of soluble Cu-, In- and Ga- multinary selenide materials; they are called metal-organic decomposition (MOD) precursors, as they are designed to decompose into the desired precursors. Reactive transfer is a two-stage process that produces CIGS through the chemical reaction between two separate precursor films, one deposited on the substrate and the other on a printing plate in the first stage. In the second stage, these precursors are rapidly reacted together under pressure in the presence of heat. The use of two independent thin films provides the benefits of independent composition and flexible deposition technique optimization, and eliminates pre-reaction prior to the synthesis of CIGS. In a few minutes, the process produces high quality CIGS films, with large grains on the order of several microns, and preferred crystallographic orientation, as confirmed by compositional and structural analysis by XRF, SIMS, SEM and XRD. Cell efficiencies of 14% and module efficiencies of 12% were achieved using this method. The atmospheric deposition processes include slot die extrusion coating, ultrasonic atomization spraying, pneumatic atomization spraying, inkjet printing, direct writing, and screen printing, and provide low capital equipment cost, low thermal budget, and high throughput.

Heat Transfer Predictions of Film Cooled Stationary Turbine Airfoils (2007)

Conventional heat transfer design methods for high temperature gas turbine airfoils decouple the internal and external flow. Thermal boundary conditions from these decoupled analyses are applied to the blade surfaces to predict turbine life. Typically, the domain for the external flow includes the hot gas path and the film cooling holes while the domain for the internal flow includes the internal flow passages and film cooling holes. The solid blade itself couples the external and internal flow and heat transfer. Since film cooling flow physics can play a significant role on the overall turbine blade heat transfer, there has been increased interest in capturing these effects by including the hole geometry in the solution procedure. Ideally, the complete turbine blade heat transfer analysis would be provided by efficient CFD simulations for the coupled problem including the internal passages, film cooling holes and hot gas path. By prescribing both the external flow and internal flow inflow/outflow boundary conditions, the hole physics can be included in the solution. The current paper presents results obtained for coupled simulations of the NASA C3X vane and VKI rotor which models the internal passages, hole geometries and hot gas path. In both cases, cooling is achieved by rows of pressure-side, leading-edge and suction-side film cooling holes. The rows are independently fed by span-wise, constant area plenums. The former has a total of 152 cylindrical cooling holes whereas the later has a total of 110 cylindrical/shaped holes. In addition, the C3X vane consists of 10 internal radial cooling passages of cylindrical cross-section. The simulations were conducted with the Shear Stress Transport (SST) model on a grid that extended into the viscous sub-layer along all surfaces. The computed surface pressure and external heat transfer coefficient distributions at mid-span are compared to experimental data for both cases. Internal heat transfer predictions are also presented and discussed.
Recombination-mediated escape from primary CD8+ T cells in acute HIV-1 infection (2014)

A major immune evasion mechanism of HIV-1 is the accumulation of non-synonymous mutations in and around T cell epitopes, resulting in loss of T cell recognition and virus escape. Here we analyze primary CD8+ T cell responses and virus escape in a HLA B*81 expressing subject who was infected with two T/F viruses from a single donor. In addition to classic escape through non-synonymous mutation/s, we also observed rapid selection of multiple recombinant viruses that conferred escape from T cells specific for two epitopes in Nef. Our study shows that recombination between multiple T/F viruses provide greater options for acute escape from CD8+ T cell responses than seen in cases of single T/F virus infection. This process may contribute to the rapid disease progression in patients infected by multiple T/F viruses.
Preparation of (Mrg-Gly-Asp)-(amino-poly(ethylene glycol)) hybrids and their inhibitory effect on experimental metastasis. (1991)

Hybrids of a fibronectin-related tripeptide (Arg-Gly-Asp) and amino-poly(ethylene glycol) were prepared and their inhibitory effect on experimental metastasis in mice was examined. The hybrids exhibited a potent inhibitory effect on the metastasis of B16 melanoma BL6.
Extracorporeal Shock Wave Therapy Is Effective In Treating Chronic Plantar Fasciitis: A Meta-analysis of RCTs (2013)

ESWT is a safe and effective treatment of chronic plantar fasciitis refractory to nonoperative treatments. Improved pain scores with the use of ESWT were evident 12 weeks after treatment. The evidence suggests this improvement is maintained for up to 12 months. We recommend the use of ESWT for patients with substantial heel pain despite a minimum of 3 months of nonoperative treatment.
Houston, we have a color issue! (2009)

Today's color imaging systems are powerful and complex entities that enable users to replicate lifelike colors. However when a color issue arises, it is very difficult to diagnose and solve. Therefore, it is beneficial to complement a color imaging system with sophisticated and user-friendly tools that help users to self-solve color issues. This paper discusses the assessment of a color printing workflow (CPW) for personal computers and the development of a web-based self-service customer support tool for color printing issues that may arise with electrophotographic color printers. We study the stages in the CPW where the colors of a document may change. From this evaluation, we find the system configuration that may have caused the change. This study provides the foundation for the development of our web-based tool, named the Color Printing Workflow Troubleshooting (CPWT) Tool. This comprehensive assessment of the CPW helps us to determine a troubleshooting strategy for our web-based tool. The set of color issues considered are those that arise when one attempts to reproduce a Pantone spot color.
Modification of constant-current circuit for coulometry (1970)

A theoretical study of a constant-current series vacuum tube circuit was given. The improved circuit was more stable for the fluctuation of load, and possible ranges of current and load were 1200 mA and 00.3 kΩ, respectively. The relative error in the determination of sodium thiosulfate by the use of this circuit was less than 0.8%.
Seismic sources at discontinuities: unambiguous moment and potency components (2018)

It is well known that for a seismic source on or near a material discontinuity, the moment tensor is ambiguous in the sense that its value depends on the exact location of the source. In this short paper, we demonstrate that this ambiguity can be resolved by considering components of the source moment and potency tensors separately. For a general source and any location ‘at’ an interface, certain components of its moment tensor and certain components of its potency tensor can be determined unambiguously. The other components depend on the exact location of the source. To investigate these results it is convenient to allow for an asymmetric moment tensor, where the antisymmetric part is physically equivalent to a torque source. These results are illustrated using ray theory for a source at a strong material contrast.
The Effect of Macromolecular Architecture in Nanomaterials:  A Comparison of Site Isolation in Porphyrin Core Dendrimers and Their Isomeric Linear Analogues (2002)

The influence of macromolecular architecture on the physical properties of polymeric materials has been studied by comparing poly(benzyl ether) dendrons with their exact linear analogues. The results clearly confirm the anticipation that dendrimers are unique when compared to other architectures. Physical properties, from hydrodynamic volume to crystallinity, were shown to be different, and in a comparative study of core encapsulation in macromolecules of different architecture, energy transduction from the polymer backbone to a porphyrin core was shown to be different for dendrimers as compared to that of isomeric four- or eight-arm star polymers. Fluorescence excitation revealed strong, morphology dependent intramolecular energy transfer in the three macromolecular isomers investigated. Even at high generations, the dendrimers exhibited the most efficient energy transfer, thereby indicating that the dendritic architecture affords superior site isolation to the central porphyrin it surrounds.
Passive Tracking of the Electrochemical Impedance of a Hybrid Electric Vehicle Battery and State of Charge Estimation through an Extended and Unscented Kalman Filter (2018)

Estimation of a lithium battery electrical impedance can provide relevant information regarding its characteristics. Currently, electrochemical impedance spectroscopy (EIS) constitutes the most recognized and accepted method. Although highly precise and robust, EIS is usually performed during laboratory testing and is not suitable for any on-board application, such as in battery electric vehicles (BEVs) because it is an instrumentally and computationally heavy method. To address this issue and on-line system applications, this manuscript describes, as a main contribution, a passive method for battery impedance estimation in the time domain that involves the voltage and current profile induced by the battery through its ordinary operation without injecting a small excitation signal. This method has been tested on the same battery with different passive voltage and current profile and has been validated by achieving similar results. Compared to the original idea presented in the published conference paper, this manuscript explains, in detail, the previously developed method of transforming the battery impedance from the frequency domain to time domain. Moreover, this impedance measurement is used to estimate more robustly the battery state of charge (SoC) through Kalman filters. In the original published conference paper, only an extended Kalman filter (EKF) was applied. However, in this manuscript, an EKF and an unscented Kalman filter (UKF) are used and their performances are compared.
Integrated Sensing and Communications with Reconfigurable Intelligent Surfaces (2022)

Integrated sensing and communications (ISAC) are envisioned to be an integral part of future wireless networks, especially when operating at the millimeter-wave (mmWave) and terahertz (THz) frequency bands. However, establishing wireless connections at these high frequencies is quite challenging, mainly due to the penetrating pathloss that prevents reliable communication and sensing. Another emerging technology for next-generation wireless systems is reconfigurable intelligent surfaces (RISs), which are capable of modifying harsh propagation environments. RISs are the focus of growing research and industrial attention, bringing forth the vision of smart and programmable signal propagation environments. In this article, we provide a tutorial-style overview of the applications and benefits of RISs for sensing functionalities in general, and for ISAC systems in particular. We highlight the potential advantages when fusing these two emerging technologies, and identify for the first time that: i) joint sensing and communications designs are most beneficial when the channels referring to these operations are coupled, and that ii) RISs offer means for controlling this beneficial coupling. The usefulness of RIS-aided ISAC goes beyond the individual obvious gains of each of these technologies in both performance and power efficiency. We also discuss the main signal processing challenges and future research directions which arise from the fusion of these two emerging technologies.
New insights into the influence of cigarette smoking on urothelial carcinogenesis: Smoking‐induced gene expression in tumor‐free urothelium might discriminate muscle‐invasive from nonmuscle‐invasive urothelial bladder cancer (2011)

Smoking is the main risk factor for urothelial bladder cancer. In former smokers the risk decreases but does not reach the low level of never smokers. This indicates reversible and permanent smoking-derived genetic alterations. Transcriptional changes may point to mechanisms, how smoking promotes urothelial bladder cancer. To identify smoking-derived transcriptional changes we performed gene expression profiling in current, former, and never smokers, using tumor and tumor-free urothelium from patients with nonmuscle-invasive urothelial bladder cancer (NMIBC) or muscle-invasive urothelial bladder cancer (MIBC). Smoking turned out to influence gene expression much less than tumor stage (NMIBC or MIBC) and tumor transformation (tumor-free or tumor). Smoking seemed to influence gene expression in patients with MIBC more strongly compared to those with NMIBC. The least irreversible changes after smoking cessation were proposed in tumor-free urothelium from patients with NMIBC. Growth factors and oncogenes were up-regulated in tumor-free urothelium from smokers with MIBC but not from smokers with NMIBC. A panel of genes up-regulated in smokers have potential for early detection and distinction of MIBC from NMIBC using tumor-free tissue.
Molecular Recognition in Biomimetic Receptors (2016)

Molecular recognition lies at the heart of biology, from the highly specific binding of an enzyme with its substrate to the vast surfaces involved in protein-protein interactions. In this chapter we outline the development of synthetic molecular receptors relevant to biology within our laboratory. Over the course of thirty years there is a substantial increase in the complexity of both the targets and receptors themselves. Early work focussed on the binding of small molecules and single functional groups, advancing to the development of peptidomimetics and a series of generalized scaffolds capable of mimicking and binding key secondary structural elements including the α-helix, β-sheet and β-strand. More recently these concepts have been applied to the mimicry of super-secondary structure, and self-assembly has been exploited to form these vast supramolecular structures in situ. This chapter explains the fundamental design features, chemical synthesis and clinical relevance of the receptors and mimics produced in our laboratory.
Diameter Selection of Single-Walled Carbon Nanotubes through Programmable Solvation in Binary Sulfonic Acid Mixtures (2007)

Pristine carbon nanotubes (CNTs) dissolve as polycarbocations in superacids through direct protonation. The solvating power of a superacid is determined by the stability of the conjugate base anion that competes with the CNTs for the dissociated proton. We have demonstrated that this equilibrium can be controlled in a predictable fashion, thus rendering the solvating power of a superacid system tunable. In this article, we show that the solvating power of chlorosulfonic acid can be changed in a desired fashion by forming binary mixtures in different proportions with a non-superacid such as methane sulfonic acid. Thus, the successive extraction of carbon nanotubes with binary acid mixtures of increasing solvating power leads to the differentiation of CNTs by their molecular geometry. We show that solvation by direct protonation is sensitive to the geometric strain at the carbon atom and, hence, to the nanotube diameter. In this respect, the direct protonation method is distinct from surfactant-based or electrical-field-based methods that distinguish metallic CNTs from semiconducting types mainly on the existence of finite density of states or not at the Fermi level. We have employed solid-state Raman spectroscopic analysis of the CNT radial breathing modes and UV−vis absorption spectroscopy and a systematic mapping method to support our conclusions. We believe the concept demonstrated in this paper holds the potential to be developed into a chemical tool kit useful in the scaleable separation of CNTs by their (n, m) types, thus paving the way for molecular carbon nanotechnology.

Long wavelength red to green emissions from {11 2 ¯ 2} semipolar multi-quantum wells on fully relaxed InGaN underlayer (2022)

Abstract In this study, we present {11 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mover accent="true"> <mml:mn>2</mml:mn> <mml:mrow> <mml:mo stretchy="true">¯</mml:mo> </mml:mrow> </mml:mover> </mml:math> 2} InGaN underlayers of high In composition and multi-quantum wells (MQWs) grown using the m-plane sapphire substrate. Fully relaxed InGaN templates with high In composition (In: ∼18%) were investigated. We used an InGaN template with an In composition of 16.5%. The photoluminescence (PL) spectrum of MQWs on the InGaN template exhibited higher emission intensity and longer emission wavelength than that on a GaN template. Moreover, an InGaN barrier was found to be more suitable than a GaN barrier for the long-wavelength (red) region in the InGaN underlayer. The intensity of the PL spectrum of InGaN/InGaN MQWs was twice as high as that of InGaN/GaN MQWs in the red emission region. Finally, we analyzed the optical polarization of the MQWs on {11 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mover accent="true"> <mml:mn>2</mml:mn> <mml:mrow> <mml:mo stretchy="true">¯</mml:mo> </mml:mrow> </mml:mover> </mml:math> 2} InGaN underlayers and its characteristics were discussed using theoretical equations.

Failure of Cytotoxic Chemotherapy, 1983&ndash;1988, and the Emerging Role of Monoclonal Antibodies for Renal Cancer (1989)

A review of 36 cytotoxic agents used singly in over 1,900 patients with renal cancer between 1983 and 1988 finds marginal antitumor activity, less than 5-10%. The future role of monoclonal antibodies for therapy of this disease may offer some hope with the recent description of rather specific phenotypic expression, URO 10+/URO 8+, suggesting the cell origin of most renal tumors from the distal portion of the proximal tubule.
Amine‐Directed Formation of B−N Bonds for BN‐Fused Polycyclic Aromatic Multiple Resonance Emitters with Narrowband Emission (2022)

Despite the remarkable multiple resonance (MR) optoelectronic properties of organic nanographenes with boron and nitrogen atoms disposed para to each other, the synthetic procedures are sophisticated with low yields and the molecular skeletons are limited. Here, a new paradigm of easy-to-access MR emitter is constructed by simplifying the multiborylation through amine-directed formation of B-N bonds while introducing an additional para-positioned nitrogen atom to trigger the MR effect. The proof-of-concept molecules exhibit narrowband emissions at 480 and 490 nm, with full width at half maxima (FWHMs) of only 29 and 34 nm. The devices based on them showed external quantum efficiencies (EQE) of >33.0 %, which remained above 24.0 % even at a high brightness of 5000 cd m<sup>-2</sup> . This is the first example of MR emitters with a B-N covalent bond, not only decreasing the synthesis difficulty but also increasing the diversity of MR skeletons for emerging new optoelectronic properties.

High-Temperature Microfluidic Synthesis of CdSe Nanocrystals in Nanoliter Droplets - eScholarship (2005)

The high-temperature synthesis of CdSe nanocrystals in nanoliter-volume droplets flowing in a perfluorinated carrier fluid through a microfabricated reactor is presented. A flow-focusing nanojet structure with a step increase in channel height reproducibly generated octadecene droplets in Fomblin Y 06/6 perfluorinated polyether at capillary numbers up to 0.81 and with a droplet:carrier fluid viscosity ratio of 0.035. Cadmium and selenium precursors flowing in octadecene droplets through a high-temperature (240-300 degrees C) glass microreactor produced high quality CdSe nanocrystals, as verified by optical spectroscopy and transmission electron microscopy. Isolating the reaction solution in droplets prevented particle deposition and hydrodynamic dispersion, allowing the reproducible synthesis of nanocrystals at three different temperatures and four different residence times in the span of four hours. Our synthesis of a wide range of nanocrystals at high temperatures, high capillary numbers, and low viscosity ratio illustrates the general utility of droplet-based microfluidic reactors to encapsulate nanoliter volumes of organic or aqueous solutions and to precisely control chemical or biochemical reactions.
The C2 fragment fromNeisseria meningitidisantigen NHBA increases endothelial permeability by destabilizing adherens junctions (2013)

Neisseria meningitidis is a human pathogen that can cause fatal sepsis and meningitis once it reaches the blood stream and the nervous system. Here we demonstrate that a fragment, released upon proteolysis of the surface-exposed protein Neisserial Heparin Binding Antigen (NHBA), by the bacterial protease NalP, alters the endothelial permeability by inducing the internalization of the adherens junction protein VE-cadherin. We found that C2 rapidly accumulates in mitochondria where it induces the production of reactive oxygen species: the latter are required for the phosphorylation of the junctional protein and for its internalization that, in turn, is responsible for the endothelial leakage. Our data support the notion that the NHBA-derived fragment C2 might contribute to the extensive vascular leakage typically associated with meningococcal sepsis.
The Future of Mobile Robotics (2010)

This textbook for advanced undergraduates and graduate students emphasizes algorithms for a range of strategies for locomotion, sensing, and reasoning. It concentrates on wheeled and legged mobile robots but discusses a variety of other propulsion systems. This edition includes advances in robotics and intelligent machines over the ten years prior to publication, including significant coverage of SLAM (simultaneous localization and mapping) and multi-robot systems. It includes additional mathematical background and an extensive list of sample problems. Various mathematical techniques that were assumed in the first edition are now briefly introduced in appendices at the end of the text to make the book more self-contained. Researchers as well as students in the field of mobile robotics will appreciate this comprehensive treatment of state-of-the-art methods and key technologies.
