A new drug delivery nanocomposite system was prepared from sodium montmorillonite (Na+Mt) intercalated with modified polyethylene glycol (PEG). PEGs of different molecular weights (400, 4000, and 8000) were modified with glycidyltrimethylammonium chloride (GTMAC) to provide terminal quaternary ammonium sites capable for attaching with Mt or other materials through ion exchange. The modified PEG-GTMAC derivatives were reacted in excess amount with Na+Mt through ion exchange. The remaining quaternary sites were used for the attachment of sodium diclofenac as a model drug. The structures of the prepared clay-modified PEG-diclofenac systems were characterized using Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). The release behavior of diclofenac from the different nanocomposites was studied at different pH values. With regard to the PEG chain length, the drug release increased with increasing PEG molecular weight (GCDIII > GCD-III > GCDII > GCDI). The kinetics of the release models was discussed using Korsmeyer-Peppas, Higuchi, and zero- and first-order models. The results of the kinetics study revealed that modified samples with PEG 400 and PEG 4000 (GCD-I and GCDII) exhibited non-Fickian diffusion (anomalous transport) while modified samples with PEG 8000 (GCDIII) exhibited super case-II transport.A convenient and simple phenol electrochemical sensor was constructed based on the Au/CeO₂/ g-C₃N₄ nanocomposites, which were obtained by loading the gold-cerium oxide (Au/CeO₂) nanoparticle on graphite-like carbon nitride (g-C₃N₄) through precipitation-reduction methods. The microstructure and morphology of Au/CeO₂/g-C₃N₄ nanocomposite were verified using different techniques such as XRD, TEM, and HRTEM. Voltammetry and amperometry methods were used to study the electrochemical performance of the constructed phenol electrochemical sensors. The results demonstrated evidently that the combination of Au/CeO₂ and g-C₃N₄ may improve sensing performances of phenol determination. The detection linear range of the sensor was 10-90 μM under the optimum parameters. The Au/CeO₂/g-C₃N₄ based electrochemical sensor also has low detection limits (2.33 μM) and high sensitivities (0.1080 mA/μM) for phenol detection. In addition, the sensor also had considerably favorable anti-interference performance. As a consequence, the sensor demonstrated that the electrochemical system provided a promising effective strategy for detection of phenol.Recently, Mo-based materials have emerged as promising candidates to replace Pt catalysts for hydrogen evolution reaction. Among these, MoO₂ holds a great promise due to its metallic conductivity. Here, we investigate the effect of V doping on the hydrogen evolution reaction activity of MoO₂ thin films. V doped MoO₂ thin films with different dopant concentrations were prepared on conductive Si substrates by co-sputtering followed by thermal sulfurization. The electrochemical measurements revealed that V doping has an adverse effect on the hydrogen evolution reaction performance of MoO₂ films, attributed to the p-type doping nature of V. This study gives insight into the effect of dopant type on the catalytic activity of hydrogen evolution reaction catalysts and provides a hint for the correct selection of dopant elements to enhance the activity of the existing catalyst materials.Zn1-xCoxO nanoparticles with three different values of 'x' (x = 0.05, 0.10, 0.15) were prepared by chemical co-precipitation process without any further heat treatment. The X-ray diffraction studies confirmed the wurtzite hexagonal crystal structure for synthesized Zn1-xCoxO nanoparticles. The dislocation density results reveal that there is an increase in the concentration of lattice imperfections with increasing the concentration of Co ions. The true values of lattice constants were calculated by using Nelson-Riley Function (NRF). Further, the average bond length (BL) were also calculated and presented. The optical and magnetic properties of Zn1-xCoxO nanoparticles were examined by room-temperature photoluminescence (PL) spectroscopy and vibrating sample magnetometer (VSM), respectively. The calculated values of magnetic susceptibility for Zn1-xCoxO nanoparticles with x = 0.05, 0.10, 0.15 were found to be 9.883×10-4, 2.29×10-2 and 2.37×10-2, respectively.45S5 bioactive glass (45S5) scaffolds were fabricated using a novel additive-manufacturing (AM) technology. A ceramic injection printer (CIP) was designed by combining injection molding and fused deposition modeling, for the fabrication of three-dimensional constructs of ceramic materials. A high fraction (50 vol%) of 45S5 powder was mixed with the thermoplastic polymer. The synthesized 45S5 composites were subjected to Brunauer-Emmett-Teller (BET) analysis, X-ray diffraction (XRD) analysis, and field-emission scanning electron microscopy (FE-SEM). The BET results of prepared 45S5 powder were confirmed to have a mean pore diameter of 11.402 nm, and specific surface area is 0.966 m²/g. The prepared 45S5/thermoplastic composite powder was subjected to Thermogravimetric/Differential thermal analysis (TG/DTA). The debinding process of polymer occurred at 192.5, 360.8, and 393 °C. The elastic modulus and ultimate stress of these scaffolds were measured to be 312.49±87.36 MPa and 21.83±6.67 MPa, respectively. The XRD results revealed the presence of Na6Ca₃Si6O18 phases. The presence of Si, Ca, P, and Na was confirmed via energy-dispersive X-ray spectroscopy (EDS). The printed scaffold exhibited amorphous calcium phosphate (ACP) expression after immersion in simulated body fluid (SBF) and also it was observed that the intensity of the crystalline phase of 45S5 was decreased, as the immersion time increases. Bioactive glass composites with the high volume fraction can be able to construct 3D complex porous scaffolds using CIP.Hearing loss is one of the major complications of diabetes mellitus and significantly lowers the quality of life of diabetic patients. In studies using diabetic animal models hearing loss have been frequently associated with damages to cochlear afferent fibers. Recent studies suggested that cochlear afferent neurons are composed of heterogeneous populations and a subgroup of neurons equipped with low level of calretinin might be more vulnerable to various noxious stimuli such as noise and neurotoxins. Here, we tested if cochlear afferent neurons deficient in the Ca2+-buffering protein calretinin are more vulnerable to hyperglycemic insults. Streptozotocin-induced (50 mg/kg, i.p.) hyperglycemic mice (>250 mg/dl) were tested. The expression patterns of calretinin in peripheral processes and the cell bodies of cochlear afferent nerve fibers were examined using immunohistochemistry and confocal microscopy. buy MEDICA16 The proportion of calretinin-poor cochlear afferent fibers was much lower in hyperglycemic mice compared to the normoglycemic control group.
