Strain Tuning and Strong Enhancement of Ionic Conductivity in SrZrO3–RE2O3 (RE = Sm, Eu, Gd, Dy, and Er) Nanocomposite Films (2015)

Fast ion transport channels at interfaces in thin films have attracted great attention due to a range of potential applications for energy materials and devices, for, solid oxide fuel cells, sensors, and memories. Here, it is shown that in vertical nanocomposite heteroepitaxial films of SrZrO 3 –RE 2 O 3 (RE = Sm, Eu, Gd, Dy, and Er) the ionic conductivity of the composite can be tuned and strongly enhanced using embedded, stiff, and vertical nanopillars of RE 2 O 3 . With increasing lattice constant of RE 2 O 3 from Er 2 O 3 to Sm 2 O 3 , it is found that the tensile strain in the SrZrO 3 increases proportionately, and the ionic conductivity of the composite increases accordingly, by an order of magnitude. The results here conclusively show, for the first time, that strain in films can be effectively used to tune the ionic conductivity of the materials.
A Platform for Robot-Assisted Intracardiac Catheter Navigation (2009)

Steerable catheters are routinely deployed in the treatment of cardiac arrhythmias.&#13;\nDuring invasive electrophysiology studies, the catheter handle is manipulated&#13;\nby an interventionalist to guide the catheter's distal section toward endocardium&#13;\nfor pacing and ablation. Catheter manipulation requires dexterity and experience,&#13;\nand exposes the interventionalist to ionizing radiation. Through the course of this research, a platform was developed to assist and enhance the navigation of the&#13;\ncatheter inside the cardiac chambers. This robotic platform replaces the interventionalist's hand in catheter manipulation and provides the option to force the catheter tip in arbitrary directions using a 3D input device or to automatically navigate the catheter to desired positions within a cardiac chamber by commanding the software to do so. To accomplish catheter navigation, the catheter was modeled as a continuum manipulator, and utilizing robot kinematics, catheter tip position control was designed and implemented. An electromagnetic tracking system was utilized to measure the position and orientation of two key points in catheter model, for position feedback to the control system. A software platform was developed to implement the navigation and control strategies and to interface with the robot, the 3D input device and the tracking system. The catheter modeling was validated&#13;\nthrough in-vitro experiments with a static phantom, and in-vivo experiments on&#13;\nthree live swines. The feasibility of automatic navigation was also veri ed by navigating to three landmarks in the beating heart of swine subjects, and comparing &#13;\ntheir performance with that of an experienced interventionalist using quasi biplane fluoroscopy. The platform realizes automatic, assisted, and motorized navigation&#13;\nunder the interventionalist's control, thus reducing the dependence of successful&#13;\nnavigation on the dexterity and manipulation skills of the interventionalist, and&#13;\nproviding a means to reduce the exposure to X-ray radiation. Upon further development,&#13;\nthe platform could be adopted for human deployment.
Acoustofluidic Medium Exchange for Preparation of Electrocompetent Bacteria Using Channel Wall Trapping (2021)

Transformation, i.e. reprogramming of bacteria by delivering exogenous genetic material (such as DNA) into the cytoplasm, is a key process in molecular engineering and modern biotechnology in general. Transformation is often performed by electroporation, i.e. creating pores in the membrane using electric shocks in a low conductivity environment. However, cell preparation for electroporation can be cumbersome as it requires the exchange of growth medium (high-conductivity) for low-conductivity medium, typically performed via multiple time-intensive centrifugation steps. To simplify and miniaturize this step, we developed an acoustofluidic device capable of trapping the bacterium Escherichia coli non-invasively for subsequent exchange of medium, which is challenging in acoustofludic devices due to detrimental acoustic streaming effects. With an improved etching process, we were able to produce a thin wall between two microfluidic channels, which, upon excitation, can generate streaming fields that complement the acoustic radiation force and therefore can be utilized for trapping of bacteria. Our novel design robustly traps Escherichia coli at a flow rate of 10 µL minute-1 and has a cell recovery performance of 47 ± 3 % after washing the trapped cells.To verify that the performance of the medium exchange device is sufficient, we tested the electrocompetence of the recovered cells in a standard transformation procedure and found a transformation efficiency of 8∙105 CFU per µg of plasmid DNA. Our device is a viable low-volume alternative to centrifugation-based methods and opens the door for miniaturization of a plethora of microbiological and molecular engineering protocols.
Novel high-index resists for 193-nm immersion lithography and beyond (2007)

A preliminary Quantitative Structure Property Relationship (QSPR) model for predicting the refractive index of small molecules and polymers at 193 nm is presented. Although at this stage the model is only semiquantitative we have found it useful for screening databases of commercially-available compounds for high refractive index targets to include in our program of synthesis of high refractive index resist polymers. These resists are targeted for use in 2<sup>nd</sup> and 3<sup>rd</sup> generation 193 nm immersion lithography. Using this methodology a range of targets were identified and synthesized via free radical polymerization. Novel resist polymers were also synthesized via Michael addition polymerization. Preliminary dose to clear experiments identified a number of promising candidates for incorporation into high refractive index resist materials. Furthermore, we have demonstrated imaging of a high index resist using water-based 193 nm immersion lithography.
Devouring the Human: (2014)

Abstract Erika Murphy's essay begins with reflection on the anecdote Hélenè Cixous tells in Stigmata of being bitten by a dog as a child. This deep bite was an epiphany of “the meat we are,” yet also emerged out of the animal's suffering. The dog becomes Job and Christ for Cixous. For Murphy, Cixous's reflections open up crucial aspects of the Johannine Jesus' corporality as flesh to be devoured and sacrificial animal. Murphy proceeds to add layer upon layer to this corporeal Christology, concluding that the call to consume Christ is an invitation to recognize the shared vulnerability of human and animal flesh, a vision that takes us to the brink of transcendence. Consumed by the animal, the human develops a taste for the divine.

Functional Organization of the Hepatitis Β Virus Enhancer (1990)

We have studied the functional constituents of the hepatitis B virus enhancer in a number of cell lines. The sequence of this enhancer, being embedded within an open reading frame of the virus, is in part evolutionarily frozen and therefore serves as a good model to investigate the fundamental enhancer elements. The hepatitis B virus enhancer contains three functionally important DNA sequence elements, EP, E, and NF-1a, each of which is bound by a distinct protein(s). The synergistic action of these elements accounts for all of the enhancer activity in a nonliver cell line and for most, but not all, of the activity in liver-derived cell lines. Multimers of the E but not of the EP element act as an autonomous enhancer. Conversely, a single element of either the E or the NF-1a element can act only when linked to the EP element. These results suggest that EP is a crucial enhancer element that acts only in interaction with a second enhancer element with intrinsic enhancer activity. Interestingly, a highly similar enhancer structure is found in a number of distinct viruses.
Line-of-Sight MIMO in aircraft-to-aicraft data links (2014)

In this paper, the capability of a generic Multiple Input Multiple Output (MIMO) Line of Sight (LoS) wireless communication simulation framework is demonstrated, that enables arbitrary, non-linear, three dimensional antenna constellations with freely selectable number of elements. In case studies, LoS MIMO gains for a fly-by and a realistic air-to-air refueling mission with different numbers of antennas in aircraft-shape-determined arrays are presented. The results confirm the hypothesis that nearly full MIMO gain is theoretically achievable in realistic airborne scenarios with moderate aircraft distances. A discussion on the practical feasibility of these impressive theoretical values concludes this publication.

Effect of Supercritical Drying Method on Microstructure and Properties of Al2O3 Composites Reinforced with Ultrafine SiC Particulate. (1999)

Mixtures of 95vol% ultrafine γ-Al2O3 powder and 5vol% ultrafine SiC powder, with average particle size of 40nm, were mixed wet-ball milling and prepared by drying their slurry with a supercritical drying method and a microwave drying method. Al2O3 specimens dispersed with ultrafine-SiC particles as the secondary phase were hot-pressed, their powders being prepared by both the above drying methods. Difference between the superitical drying and the microwave drying method on the microstructure of Al2O3/5vol% SiC composites was investigated. Dense Al2O3/SiC composites were obtained at lower hot-pressing temperatures when the mixture was prepared by supercritical drying method. Influence of the drying method on the γ- to α-Al2O3 transition behavior was also examined. Al2O3/SiC powder dried by the supercritical drying method showed narrow particle size distribution and the formation of soft agglomerates. Al2O3/SiC composite sintered by hot-pressing the powder dried with the supercritical drying method indicated relatively higher strength, whereas the strength of Al2O3/SiC composite through microwave drying method was low and had the large scatter.

Complexes of dimethyltin dihalides with N-methylpyrrolidinone, C12H24N2O2X2Sn (X = Cl, Br or I) (2000)

The single-crystal X-ray structure determinations of the title complexes, cis-di­chloro-trans-di­methyl-cis-bis(N-methyl­pyr­rolidin-2-one-O)­tin(IV), [Sn(CH3)2Cl2(C5H9NO)2], cis-di­bromo-trans-di­methyl-cis-bis(N-methyl­pyrrolidin-2-one-O)tin­(IV), [SnBr2(CH3)2(C5H9NO)2], and cis-di­iodo-trans-di­methyl-cis-bis(N-methyl­pyrrolidin-2-one-O)­tin(IV), [Sn(CH3)2I2(C5H9NO)2], show that those tin complexes in which coordination of the lactam ligand to SnIV is realized via oxygen exhibit a distorted octahedral geometry.
Close correlation of the cardioprotective effect of FK409, a spontaneous NO releaser, with an increase in plasma cyclic GMP level (1994)

FK409 ((±)‐(E)‐ethyl‐2‐[(E)‐hydroxyimino]‐5‐nitro‐3‐hexeneamide), which has been reported by us to be a new spontaneous nitric oxide (NO) releaser, prevented myocardial infarction following occlusion and reperfusion in rat coronary artery and increased plasma cyclic GMP level in rats, dose‐dependently and significantly at 32 mg kg −1 . Isosorbide dinitrate (ISDN), which is the most popular orally active NO donor used in the treatment of ischaemic cardiovascular diseases, did not show significant effects at 32 mg kg −1 in either experiment. Therefore, it is suggested that FK409 can attenuate myocardial injury during ischaemia and reperfusion in contrast to ISDN and a change in plasma cyclic GMP level may serve as an indicator of the cardioprotective effect of NO‐releasing drugs.
Layered polymer whole structure health monitoring using capacitance sensing (2010)

Capacitive sensors have a wide field of applications for measuring a parameter that results in displacement of parallel capacitor plates, displacement of the sandwiched dielectric material, or a change in the dielectric's material properties. This theory of parallel plate capacitance can be used in a layered polymer structure to allow continuous whole structure health monitoring. The sensor itself is created from integrated layers of conductive polymers separated by a polymer layer which has a high dielectric constant. This paper is an overview of current research into the application of this type of sensor. When incorporated into a hydraulic hose, it was found that capacitance measurement of the sensor increased slightly noticeably at the start of failure in a linear manner as pressure inside the hose increased. Similar results are seen when investigating on-highway tires and lumbar total disc replacement.

Synthesis and physical properties of laterally fluoro substituted ferroelectric liquid crystals with a fluoro substituted chiral terminal chain (2001)

A new series of ferroelectric liquid crystals (FLCs) has been designed for active matrix displays based upon the chiral smectic C phase. The FLCs have been derived from optically active fluorinated alkanols and a laterally fluoro substituted biphenylyl-1,3-dioxan core. Their physical properties such as spontaneous polarization, current response time, and tilt angle have been determined. The FLC derived from 2-fluoro-octanol showed a very short current response time of 10μs at T Sm*-N* - T= 10°C, while another FLC with the same core derived from 5-fluoro-octanol gave a value of 150μs.
Annealing and N2 Plasma Treatment to Minimize Corrosion of SiC-Coated Glass-Ceramics (2020)

To improve the chemical durability of SiC-based coatings on glass-ceramics, the effects of annealing and N<sub>2</sub> plasma treatment were investigated. Fluorapatite glass-ceramic disks were coated with SiC via plasma-enhanced chemical vapor deposition (PECVD), treated with N<sub>2</sub> plasma followed by an annealing step, characterized, and then immersed in a pH 10 buffer solution for 30 days to study coating delamination. Post-deposition annealing was found to densify the deposited SiC and lessen SiC delamination during the pH 10 immersion. When the SiC was treated with a N<sub>2</sub> plasma for 10 min, the bulk properties of the SiC coating were not affected but surface pores were sealed, slightly improving the SiC's chemical durability. By combining N<sub>2</sub> plasma-treatment with a post-deposition annealing step, film delamination was reduced from 94% to 2.9% after immersion in a pH 10 solution for 30 days. X-ray Photoelectron spectroscopy (XPS) detected a higher concentration of oxygen on the surface of the plasma treated films, indicating a thin SiO<sub>2</sub> layer was formed and could have assisted in pore sealing. In conclusion, post-deposition annealing and N<sub>2</sub> plasma treatment where shown to significantly improve the chemical durability of PECVD deposited SiC films used as a coating for glass-ceramics.

We present an analytical model for the current transport in polycrystalline (poly)Si/interfacial oxide/monocrystalline ( c)-Si base junctions, which consistently describes the symmetrical behavior of an n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> poly-Si emitter/ p c-Si base and p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> poly-Si emitter/ n c-Si base configuration. Our model is focused on a regime within which the current transport is possibly dominated by a flow through oxide pinholes rather than by tunneling. For an emitter region assumed to form underneath the interfacial oxide by diffusion of dopants from the poly-Si into the c-Si, we calculate the minority charge carrier distribution and the resistance implied for majority charge carriers. With reasonable parameters, our model simultaneously reproduces the experimentally observed low emitter saturation current densities and low junction resistances values. Our model provides a plausible explanation for the high current gain observed in p-n-p and n-p-n bipolar transistors featuring a poly-Si emitter. In principle, the obtained correlation between recombination current and series resistance is analogous to the situation in a base region of a solar cell with local rear contacts. Thus, a poly-Si/ c-Si junction can be explained within the framework of a classical p-n junction picture for a passivated, locally contacted emitter.
Mechanism for ammonia-induced promotion of gastric carcinogenesis in rats (1995)

Although an association is suggested between gastric cancer and prior infection with Helicobacter pylori (HP), the role of HP in gastric carcinogenesis remains obscure. HP has potent urease activity and produces ammonia, a factor causing HP-related gastroduodenal mucosal lesions. In this study, rats were examined in an effort to determine effects of ammonia on gastric carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). After pretreatment with MNNG (83 mg/l) for 24 weeks, a solution of either 0.01% ammonia or plain tap water was administered to the animals as drinking water for an additional 24 weeks. The administration of the 0.01% ammonia solution significantly increased the incidence and number of cancers in the glandular stomach. The numbers of cases in which these cancers penetrated the muscle layer or deeper and of low-grade differentiated adenocarcinomas were significantly higher in rats receiving the ammonia solution. Continuing administration of ammonia accelerated cell proliferation in the gastric mucosa, but had no effect on the serum gastrin level. Therefore, gastric ammonia, which stimulates mucosal cell proliferation, appears to be an important promoter in carcinogenesis in rats and possibly in the HP-related gastric carcinogenesis in humans.
The Endocannabinoid System and Multiple Sclerosis (2008)

Multiple sclerosis (MS) is a neurodegenerative disease that is characterised by repeated inflammatory/demyelinating events within the central nervous system (CNS). In addition to relapsing-remitting neurological insults, leading to loss of function, patients are often left with residual, troublesome symptoms such as spasticity and pain. These greatly diminish "quality of life" and have prompted some patients to self-medicate with and perceive benefit from cannabis. Recent advances in cannabinoid biology are beginning to support these anecdotal observations, notably the demonstration that spasticity is tonically regulated by the endogenous cannabinoid system. Recent clinical trials may indeed suggest that cannabis has some potential to relieve, pain, spasms and spasticity in MS. However, because the CB(1) cannabinoid receptor mediates both the positive and adverse effects of cannabis, therapy will invariably be associated with some unwanted, psychoactive effects. In an experimental model of MS, and in MS tissue, there are local perturbations of the endocannabinoid system in lesional areas. Stimulation of endocannabinoid activity in these areas either through increase of synthesis or inhibition of endocannabinoid degradation offers the positive therapeutic potential of the cannabinoid system whilst limiting adverse events by locally targeting the lesion. In addition, CB(1) and CB(2) cannabinoid receptor stimulation may also have anti-inflammatory and neuroprotective potential as the endocannabinoid system controls the level of neurodegeneration that occurs as a result of the inflammatory insults. Therefore cannabinoids may not only offer symptom control but may also slow the neurodegenerative disease progression that ultimately leads to the accumulation of disability.
