Synthesis of Black TiOx Nanoparticles by Mg Reduction of TiO2 Nanocrystals and their Application for Solar Water Evaporation (2016)

TiO x ( x &lt; 2) nanoparticles with tunable colors from white to gray to blue–gray to black are synthesized by magnesium (Mg) reduction of white P25 TiO 2 nanocrystals followed by removal of excess Mg with aqueous HCl and distilled water. Increasing amounts of Mg smoothly decrease the oxygen content in TiO x which is responsible for the gradual increase in light absorption and concomitant darkening of its color from white to black with decreasing values of x . The as‐synthesized TiO x nanoparticles are spin‐coated onto the surface of a stainless steel mesh followed by surface superhydrophobization in order to test their performance as a solar water evaporator. Results from the tests show that the black TiO x efficiently generates water vapor with a solar thermal conversion efficiency as high as 50% under solar‐simulated light irradiance at an intensity of 1000 W m –2 (1 Sun). Moreover, TiO x nanoparticles have inherent advantages over other materials used for solar water desalination, such as their tunable light absorption, low‐cost, low‐toxicity, superhydrophobicity, and chemical stability.
A Modular Sydnone Cycloaddition/Suzuki−Miyaura Cross-Coupling Strategy to Unsymmetrical 3,5-Bis(hetero)aromatic Pyrazoles (2010)

The [3 + 2] dipolar cycloaddition of 4-halosydnones with 1-haloalkynes opens a straightforward access to 3,5-dihalopyrazoles, valuable scaffolds for the elaboration of unsymmetrically 3,5-substituted pyrazole derivatives via site-selective Pd-catalyzed cross-coupling reactions. For instance, the flexible introduction of different (hetero)aryl substituents at the C-5 and C-3 positions of the PMP-protected pyrazole nucleus was achieved in a one-pot operation via sequential reactions with various boronic acids.

An injection seeded single frequency Nd:YAG Q-switched laser with precisely controllable laser pulse firing time (2010)

We have realized a single frequency Q-switched Nd:YAG laser with precisely controllable lasing time and thus enabled synchronization of multi-laser systems. The use of injection seeding to the slave ring oscillator results in unidirectional Q-switched laser oscillation with suppression of bidirectional Q-switched oscillation that otherwise would be initiated from spontaneous emission if the seeding laser is not present. Under normal condition, the cavity is high in loss during the pumping period; then a Pockels cell opens the cavity to form the pulse build up, with a second Pockels cell to perform cavity dumping, generating the Q-switched pulse output with optimized characteristics. The two Pockels cells can be replaced by a single unit if an adjustable gated electrical pulse is applied to the Pockels cell in which the pulse front is used to open the cavity and the falling edge to dump the laser pulse. Proper selection of the pump parameters and Pockels-cell gating enables operation of the system in a mode in which the Q-switched pulse can be formed only under the seeding condition. The advantage of the realized regime is in stable laser operation with no need in adjustment of the seeded light wavelength and the mode of the cavity. It is found that the frequency of the Q-switched laser radiation matches well to the injected seeded laser mode. By using two-stage amplifiers, an output energy better than 300 mJ has been achieved in MOPA configuration without active control of the cavity length and with pulse width adjustability from several nanoseconds to 20 ns. The Q-switched oscillator operates not only at precisely controlled firing time but also can be tuned over wide range. This will enable multi-laser systems synchronization and frequency locking down each other if necessary.
Effect of Calcium - Potassium Equilibrium on Tomato Plants Grown Hydroponically (2023)

In order to study the effect of calcium-potassium Equilibrium in hydroponics culture nutrient solution on growth, nutritional status and productivity of tomato plants (cv. Red spring) an experiment was conducted at a private hydroponic farm in Qena Governorate through the Soils and Water department, faculty of Agriculture, South Valley University, Egypt. The site is at (latitude 26° 11' 22.2'' N to Longitude 32° 44' 25.5'' E), and 81 m above sea level.Tomato plants were grown hydroponically using six types of nutrient solution: 1) standard solution adapted with nutritive needs of tomato plants (balanced in Ca and K), 2) Ca deficient solution, 3) Ca excess solution, 4) K deficient solution, 5) K excess solution and 6) Ca and K excess solution.The obtained results showed that, Compared to balanced Ca-K solution or those deficient in Ca or K content, “Red Spring” tomato plants grown in nutrient solution rich Ca or in K or rich in both Ca and K present higher and significant growth parameters, cluster number/plant and fruit numbers/cluster. Significant differences were obtained in leaves mineral contents (N, P, K, Ca, Fe and Zn) as a result of varying Ca-K equilibrium of nutrient solution. However, the antagonism between Ca, K and Mg Clearly observed. Fruit physical and chemical characteristics significantly affected by varying the Ca-K equilibrium in the nutrient solution.
Very Small-Sized Resonator Filter Using Shear Horizontal Wave on Quartz (2001)

By composing interdigital transducers (IDTs) and reflectors consisting of films made of a heavy metal such as Au, Ta or W on an ST cut 90°X propagation (direction perpendicular to X-axis) quartz substrate, the authors realized a new type of shear horizontal (SH) wave. This wave has an excellent temperature characteristic, a large electromechanical coupling factor ( k ), and a large reflection coefficient at reflector electrodes. The square of this electromechanical coupling factor ( k 2 =0.28∼0.34%) and the reflection coefficient at reflector electrodes are 2.2∼2.6 times and 30∼35 times, respectively, as large as those of a Rayleigh wave on an ST cut X propagation quartz substrate. The authors applied this technology to filters for the first intermediate frequency (first IF) stage of a global system for mobile communications (GSM) in the nominal center frequency from 200 to 400 MHz. As a result, we succeeded in developing the first IF filter having a low insertion loss, an excellent temperature characteristic (frequency shift: 1 ppm/°C) and a small package size (3×3 mm 2 ), which is as small as a radio frequency (RF) surface acoustic wave (SAW) filter, for the first time.
Surge Analysis and Snubber Design for a Full-Bridge Isolated DC-DC Converter in HVDC Power Distribution Systems (2013)

In an isolated DC-DC converter utilized in a high-voltage DC power distribution system for data centers, a large surge voltage occurs across the secondary-side diodes owing to the transformer's leakage inductance, necessitating diodes with a large withstand voltage. However, these diodes cause large power losses owing to relatively large ON-resistances. First, this study analyzes surge occurrences using a high-frequency equivalent circuit. Second, the surge-suppression capability of a simple snubber capacitor is examined, and the surge-voltage evaluation through analysis using high-frequency equivalent circuits is described. This is followed by experimental confirmation with SiC diodes. Finally, the minimum capacitance of the surge-snubber capacitor is determined for miniaturization.
Development of Rust Stripping System using High Power Laser (2005)

The repainting cycle depends on removal of rust in maintenance of outdoor steel-frame structural facilities. However existing stripping process, which is usually made by hands with brushes, cannot strip the rust completely in maintenance of power transmission towers, for example. To solve this problem, we investigated laser fluence and pulse width for removal of rust using DPSSL (Diode Pumped Solid State Laser), and selected optimum laser supply. Then we checked the effect of laser stripping on prolongation of the repainting cycle compared with the conventional stripping process. Utilizing results of the research, we developed rust stripping system using DPSSL. From the results of field trial of rust removal operation using this system at high places of a power transmission tower, possibility of practical use of the system for the maintenance was confirmed.

Slow AV Nodal Pathway Ablation Utilizing a Unique Temperature Controlled Radiofrequency Energy System (1997)

Thirty-nine consecutive patients with symptomatic AV nodal reentrant tachycardia (AVNRT) underwent temperature guided slow AV nodal pathway ablation (group 1). Forty-three consecutive patients undergoing nontemperature guided slow AV nodal pathway ablation late in our experience compose the control population (group 2). Slow pathway ablation was achieved in all patients of both groups. The mean fluoroscopy and ablation times for group 1 were significantly shorter than for group 2 (26.1 +/- 14.9 vs 33.9 +/- 18.9 min, P < 0.05; 19.9 +/- 12.1 vs 30.9 +/- 23.3 min, P < or = 0.02). There were no episodes of coagulum formation in group 1, while there were 15 episodes (7.1% of energy applications) in group 2 (P = 0.0006) despite a significantly higher applied power in group 1 (53.4 +/- 25.1 vs 35.6 +/- 9.5W, P = 0.0001). Successful energy applications were associated with significantly higher temperatures than unsuccessful applications in group 1 (55.6 degrees +/- 5.8 degrees C vs. 52.9 degrees +/- 6.8 degrees C, P < or = 0.03). The minimum temperature required for successful ablation was 48 degrees C for two patients (5%) and was > or = 50 degrees C for the remainder of patients (37/39 [95%]). The catheter ablation system used in this study was safe, effective, and prevented coagulum formation while delivering relatively high power. In addition, shorter ablation times and radiation exposure were seen with this system. Although successful energy applications and the production of junctional rhythm were associated with higher achieved temperatures, temperature alone did not predict either endpoint. Future prospective, randomized trials are needed to confirm these findings and further evaluate the value of temperature monitoring.
Formulation and Delivery Mode Affect Disposition and Activity of Tyrphostin-Loaded Nanoparticles in the Rat Carotid Model (2001)

Poor drug residence in the arterial wall hinders clinical implementation of local drug delivery strategies for the treatment of restenosis. A rat carotid model of vascular injury and intraluminal delivery of tyrphostin-containing polylactic acid (PLA) nanoparticles (NPs) were used to determine the relationship between residence properties and biological activity of different formulations and administration modes. The effects of delivery modes (denudation and delivery time) and formulation variables (adsorbed vs encapsulated drug, and NP size) on arterial drug/NP retention were examined. Antirestenotic effects of large (160 nm) and small (90 nm) tyrphostin-containing NPs, surface-absorbed tyrphostin, and systemic treatment were compared. Fluorescent NPs were used to study the spatial distribution of the carrier in the arterial wall. The decrease in arterial tyrphostin level over time fitted a biexponential model. Delivery time and pressure, endothelium integrity, particle size, and drug-polymer association affected local pharmacokinetics and the antirestenotic results after 14 days. The PLA-based tyrphostin NP formulation ensured a prolonged drug residence at the angioplasty site after single intraluminal application. Several readily adjustable formulation and procedural factors considerably modified arterial ingress of the drug-loaded NPs and governed their subsequent redistribution, tissue binding, elimination, and ensuing antirestenotic effect.
A Method for the Asymmetric Hydrosilylation of N-Aryl Imines (2000)

[reaction: see text] The asymmetric reduction of N-aryl imines to yield chiral amines with enantiomeric excesses above 90% was achieved. Ethylenebis(eta5-tetrahydroindenyl)titanium difluoride ((EBTHI)TiF2, 1) was employed as the precatalyst with polymethylhydrosiloxane (PMHS) as the stoichiometric reducing agent. A variety of N-aryl imines derived from nonaromatic ketones were reduced with high ee.
Experiences of healthcare professionals with support for mesothelioma patients and their relatives: Identified gaps and improvements for care (2021)

Our study showed that psychosocial support and palliative care for patients with mesothelioma could be improved. A more fluent transition between primary and secondary cancer care and early integration of psychosocial support and palliative care is advised. Lastly, more attention is needed for psychosocial and palliative care in the basic medical training of healthcare professionals.
Effects of Intravenous and Oral Esomeprazole in the Prevention of Recurrent Bleeding from Peptic Ulcers after Endoscopic Therapy (2014)

High-dose oral esomeprazole at 40 mg BID may be considered as a useful alternative to IV bolus plus infusion of esomeprazole in the management of ulcer bleeding in patients who are not candidates for high-dose IV infusion. However, as this study was stopped prematurely and was not designed as an equivalency trial, a much larger study would be necessary to document whether there is equivalency or non-inferiority of the two treatments in a heterogeneous patient population.
Using government purchasing power to reduce equipment standby power (2003)

Although the government sector represents only 10 to 15 percent of the economy in most countries, carefully targeted public procurement can play a significant role in market transformation through its influence on both buyers and suppliers. Government leadership in energy-efficient purchasing can set an example for other buyers, while creating opportunities for leading manufacturers and distributors to increase their sales and market share by offering energy-efficient products at competitive prices. Under proper circumstances, a highly visible government purchasing policy can have a disproportionately large influence on the market for efficient products. In the United States, President Bush signed an Executive Order in 2001 directing all federal agencies to buy products with low standby power (1 watt or less where possible). This represents a deliberate choice to use government purchasing - rather than regulations or incentives - as a market-based strategy to encourage energy savings. It also builds upon existing efforts to encourage Federal purchase of energy-efficient products (Energy Star products and others in the top 25th percentile of efficiency). This paper summarizes the Federal Energy Management Program s first 18 months of experience in implementing this Executive Order, including analysis of data on standby power, interactions with manufacturers and industry groups, and the relationship between these efforts and other federal programs concerning product labelling, testing, rating, and efficiency standards. After five years of implementing low-standby power purchasing, we estimate energy savings for federal agencies alone at about 230 GWh/year (worth US$14 million), with spillover effects on the broader market that will save all US consumers nearly 4000 GWh/year (US$300 million).
Nanoscale hybrid implant surfaces and Osterix‐mediated osseointegration (2021)

Endosseous implant surface topography directly affects adherent cell responses following implantation. The aim of this study was to examine the impact of nanoscale topographic modification of titanium implants on Osterix gene expression since this gene has been reported as key factor for bone formation. Titanium implants with smooth and nanoscale topographies were implanted in the femurs of Osterix-Cherry mice for 1-21 days. Implant integration was evaluated using scanning electron microscopy (SEM) to evaluate cell adhesion on implant surfaces, histology, and nanotomography (NanoCT) to observe and quantify the formed bone-to-implant interface, flow cytometry to quantify of Osterix expressing cells in adjacent tissues, and real-time PCR (qPCR) to quantify the osteoinductive and osteogenic gene expression of the implant-adherent cells. SEM revealed topography-dependent adhesion of cells at early timepoints. NanoCT demonstrated greater bone formation at nanoscale implants and interfacial osteogenesis was confirmed histologically at 7 and 14 days for both smooth and nanosurface implants. Flow cytometry revealed greater numbers of Osterix positive cells in femurs implanted with nanoscale versus smooth implants. Compared to smooth surface implants, nanoscale surface adherent cells expressed higher levels of Osterix (Osx), Alkaline phosphatase (Alp), Paired related homeobox (Prx1), Dentin matrix protein 1 (Dmp1), Bone sialoprotein (Bsp), and Osteocalcin (Ocn). In conclusion, nanoscale surface implants demonstrated greater bone formation associated with higher levels of Osterix expression over the 21-day healing period with direct evidence of surface-associated gene regulation involving a nanoscale-mediated osteoinductive pathway that utilizes Osterix to direct adherent cell osteoinduction.
Overcoming Challenges to Make Bacteriophage Therapy Standard Clinical Treatment Practice for Cystic Fibrosis (2021)

Individuals with cystic fibrosis (CF) are given antimicrobials as prophylaxis against bacterial lung infection, which contributes to the growing emergence of multidrug resistant (MDR) pathogens isolated. Pathogens such as <i>Pseudomonas aeruginosa</i> that are commonly isolated from individuals with CF are armed with an arsenal of protective and virulence mechanisms, complicating eradication and treatment strategies. While translation of phage therapy into standard care for CF has been explored, challenges such as the lack of an appropriate animal model demonstrating safety <i>in vivo</i> exist. In this review, we have discussed and provided some insights in the use of primary airway epithelial cells to represent the mucoenvironment of the CF lungs to demonstrate safety and efficacy of phage therapy. The combination of phage therapy and antimicrobials is gaining attention and has the potential to delay the onset of MDR infections. It is evident that efforts to translate phage therapy into standard clinical practice have gained traction in the past 5 years. Ultimately, collaboration, transparency in data publications and standardized policies are needed for clinical translation.

Influence of plantation climate and storage time on thermal and viscoelastic properties of natural rubber (2021)

<abstract> The Sociedad de Caucho Colombo Argentina (SOCCA) collected natural rubber (NR) from Yarima, Colombia, for seven months spanning two years. The unvulcanized NR was used to conduct a preliminary study, part of a long-term study, to uncover some underlying mechanisms in charge of imparting variation between NR batches, such as the collection site's rainfall conditions and storage period by using calorimetry, rheometry, and a dynamic mechanical analyzer. The ultrasound study found that an increase in monthly rainfall increased the material's elastic constant at 10 MHz, and the crystallization study uncovered that the amount of crystallization decreased with increased rain while remaining relatively constant if rainfall was within the recommended rainfall amount for the tree. Additionally, stress relaxation measurements revealed that an increase in rainfall suggested an increase in the material's temperature sensitivity. The temperature sensitivity relates to the material's processability in which an increase in temperature with high sensitivity will have a more drastic decrease in stress during a relaxation test compared to a material with low sensitivity. </abstract>
