Modulating the Morphological Features of Hydrothermally Derived Nickel Cobaltite for Supercapacitor Application: Role of Precursor Anions.

Morphologically engineered porous electrodes show great promise in energy applications as they exhibit improved electrochemical activity owing to increased electrical conductivity, increased surface area, and a shorter path length for ion transport. Herein, the role of precursors (chlorides, acetates and nitrates) on the crystallinity and textural features of Nickel Cobaltite, obtained by the controlled precipitation through hydrothermal synthesis, is studied. The synthesis yielded urchin like structures with morphological variations in substructures based on the precursor anion types.

Sodium silicate-derived aerogels: effect of processing parameters on their applications.

Inorganic silica aerogels derived from sodium silicate are voluminous three-dimensional open networks with exceptional properties such as a density as low as ∼100 kg m, high porosity (∼99%), low thermal conductivity (∼0.01 W m K), high specific surface area (∼1000 m g), low refractive index (∼1.05) and high optical transmittance (∼95%) depending on their preparation conditions.

Degradation-Dependent Controlled Delivery of Doxorubicin by Glyoxal Cross-Linked Magnetic and Porous Chitosan Microspheres.

Glyoxal cross-linked porous magnetic chitosan microspheres, GMS (∼170 μm size), with a tunable degradation profile were synthesized by a water-in-oil emulsion technique to accomplish controlled delivery of doxorubicin (DOX), a chemotherapeutic drug, to ensure prolonged chemotherapeutic effects. The GMS exhibit superparamagnetism with saturation magnetization, = 7.2 emu g.

Correlation of Transabdominal Ultrasonography and Cystoscopy in Follow-up of Patients with Non-muscle Invasive Bladder Cancer.

Cystoscopy (CS) is considered to be the gold standard in the follow-up of non-muscle invasive bladder cancer. However, CS is invasive, time-consuming, and expensive. On the other hand, modern sensitive transducers have improved the imaging of urinary tract rendering transabdominal ultrasonography (US) more effective in visualizing intraluminal filling defects in the bladder than it was in the past.

Surface modification induced enhanced CO sorption in cucurbit[6]uril, an organic porous material.

The CO adsorption properties of an organic macrocycle, cucurbit[6]uril (CB[6]), have been evaluated through experimental and theoretical studies. Quantum mechanical calculations show that CB[6] is capable of adsorbing the CO molecule selectively within its cavity relative to nitrogen. Adsorption experiments at 298 K and at 1 bar pressure gave a CO adsorption value of 1.

Role of precursors on the photophysical properties of carbon nitride and its application for antibiotic degradation.

In this paper, we provide a comprehensive evaluation of graphitic carbon nitride (CN) powders derived from the four different precursors melamine, cyanamide, thiourea, and urea for the photocatalytic degradation of tetracycline (TC) antibiotic under sunlight irradiation. The powders were synthesized by employing the conventional thermal decomposition method. The synthesized powders were examined using different characterization tools for evaluating the photophysical properties.

Graphene Oxide Sheathed ZIF-8 Microcrystals: Engineered Precursors of Nitrogen-Doped Porous Carbon for Efficient Oxygen Reduction Reaction (ORR) Electrocatalysis.

Nitrogen containing mesoporous carbon obtained by the pyrolysis of graphene oxide (GO) wrapped ZIF-8 (Zeolitic Imidazolate Frameworks-8) micro crystals is demonstrated to be an efficient catalyst for the oxygen reduction reaction (ORR). ZIF-8 synthesis in the presence of GO sheets helped to realize layers of graphene oxide over ZIF-8 microcrystals and the sphere-like structures thus obtained, on heat treatment, transformed to highly porous carbon with a nitrogen content of about 6.12% and surface area of 502 m/g.

Hydrophobic and Metallophobic Surfaces: Highly Stable Non-wetting Inorganic Surfaces Based on Lanthanum Phosphate Nanorods.

Metal oxides, in general, are known to exhibit significant wettability towards water molecules because of the high feasibility of synergetic hydrogen-bonding interactions possible at the solid-water interface. Here we show that the nano sized phosphates of rare earth materials (Rare Earth Phosphates, REPs), LaPO4 in particular, exhibit without any chemical modification, unique combination of intrinsic properties including remarkable hydrophobicity that could be retained even after exposure to extreme temperatures and harsh hydrothermal conditions. Transparent nanocoatings of LaPO4 as well as mixture of other REPs on glass surfaces are shown to display notable hydrophobicity with water contact angle (WCA) value of 120° while sintered and polished monoliths manifested WCA greater than 105°.

Laparoscopic pyelolithotomy: An emerging tool for complex staghorn nephrolithiasis in high-risk patients.

Objectives: To evaluate the effectiveness of laparoscopic pyelolithotomy (LP) for staghorn stones (>3-4 cm) in patients with chronic liver disease or coronary artery disease.

Patients And Methods: In all, 49 patients underwent LP; they were divided into four groups, with stones in group 1 in the renal pelvis only, in group 2 in the renal pelvis and one calyx, in group 3 in the renal pelvis and two calyces, and in group 4, in the renal pelvis and more than two calyces. Patient demography, stone characteristics, surgical outcomes and complications were evaluated.

Bifunctional lanthanum phosphate substrates as novel adsorbents and biocatalyst supports for perchlorate removal.

Porous lanthanum phosphate substrates, obtained by an environmentally benign colloidal forming process employing methyl cellulose, are reported here as excellent adsorbents of perchlorate with >98% efficiency and with 100% reusability. Additionally, the effectiveness of such substrates as biocatalyst supports that facilitate biofilm formation of perchlorate reducing microbes (Serratia marcescens NIIST 5) is also demonstrated for the first time. The adsorption of perchlorate ions is attributed to the pore structure of lanthanum phosphate substrate and the microbial attachment is primarily ascribed to its intrinsic hydrophobic property.

Laparoscopic adrenal surgery in children: Lessons from a single centre experience.

Purpose: Although commonly performed in adults, laparoscopic adrenalectomy in children is performed only in centres with advanced laparoscopic expertise.

Materials And Methods: This is a retrospective analysis of laparoscopic adrenalectomies performed at a single centre between January 2003 and May 2010. After preoperative evaluation with biochemical assays and radiologic imaging, surgery was performed by using the lateral transabdominal approach in all patients.

Concomitant laparoscopic urological procedures: Does it contribute to morbidity?

Aim: With advancement in minimal access surgery two laparoscopic procedures can be combined together shortening the total hospital stay, decreasing morbidity and overall reduced cost. Combining two laparoscopic procedures in a single session has been reported in general surgery. Very few articles are available in literature with regard to combined urological laparoscopic surgeries.

Adult presentation of congenital ectopic vas deferens insertion into ureter with unilateral renal agenesis.

Congenital vas deferens-ureteral connection is known to cause epididymitis and scrotal infections in infancy and childhood. Embryologically, the anomaly results from an abnormal high origin of the ureteric bud on the mesonephric duct with a resultant long common excretory duct being incompletely absorbed into the bladder. This report describes a rare adult presentation in a 20-year-old man where evaluation with ultrasonograms, isotope renogram, magnetic resonance imaging scans and cystoscopy with retrograde instillation of contrast into the right ureter confirmed aberrant insertion of vas deferens into the ureter associated with ureterocele and ipsilateral renal agenesis.
