The present study investigates the photocatalytic degradation of three quinolone antibiotics (i.e., Flumequine (FLU), Oxolinic Acid (OA) and Nalidixic Acid (NA)) in mono-, binary and ternary compound systems. The closed-loop step photo-reactor and TiO 2 impregnated on cellulosic paper as supported photo-catalyst in presence of UV light irradiation ...
A new type of sandwiched nanosheets 3D MoS2/[email protected] is synthesized by supramolecular self-assembly methods, as a novel and excellence electrode material. The surface characterization techniques show that the sandwiched 3D MoS2/[email protected] possesses rich porosity and large specific area, which is convenient for electrolyte ion transportation and beneficial ...
We report the mid-IR s-SNOM surface characterization of a chalcogenide glass photo-inscribed by ultrashort laser pulses. Imaging allows to access to the morphology and the optical properties of the material at nanoscale, unravelling topographical and optical contrasts resulting from the laser inscription process. © 2019 IEEE.
El propósito de este estudio fue evaluar el efecto del uso de los auxiliares de higiene oral combinados con agentes blanqueadores sobre la microdureza y la micro-morfología del esmalte dental. Materiales y métodos. Se utilizaron 40 incisivos humanos y se seccionaron para obtener muestras de 4x4 mm los cuales se dividieron en cuatro grupos de estudi...
Ce travail s’inscrit dans le cadre général du développement de biomatériaux ostéoinducteurs pour la réparation de grands défauts osseux. L’étude est une contribution à la compréhension des interactions physiques et chimiques entre des céramiques phosphocalciques et deux protéines d’intérêt : la fibronectine, protéine d’adhésion cellulaire, et le VE...

Roughness and curvature of diamond-like carbon (DLC) surface coatings change with both scale and direction of a measurement. However, the changes are not detected by currently used standard parameters which are designed to work with isotropic surfaces at a single scale, thus providing only a limited information about multiscale and directional roug...

In this study, 25,27-bis(3-mercaptopropoxyl)-26,28-dihydroxy calix[4]arene was successfully synthesized from the reaction of calix[4]arene-dialkylbromide derivative with thiourea. The structure of 25,27-bis(3-mercaptopropoxyl)-26,28-dihydroxy calix[4]arene was fully characterized using 1HNMR, 13CNMR and elemental analysis techniques. The obtained m...

In order to clarify the surface features of zirconia ceramics fabricated by ultrasonic vibration-assisted grinding (UVAG), five geometric parameters (width dw, depth hd, length ld, spacing df and number N) of UVAG surface are selected to characterize UVAG surface topography. In this study, firstly, the mathematic modeling between five geometric par...

High-density inorganic nanoparticles have shown promise in medical applications that utilize radiation including X-ray imaging and as radiation dose enhancers for radiotherapy. We have developed an aqueous synthetic method to produce small (~ 2 nm) iridium nanoparticles (IrNPs) by reduction of iridium(III) chloride using a borohydride reducing agen...
