A novel micro/nanoscale rough structured superhydrophilic hybrid-coated mesh that shows underwater superoleophobic behavior is fabricated by spray casting or dipping nanoparticle–polymer suspensions on stainless steel mesh substrates. Water droplets can spread over the mesh completely; meanwhile, oil droplets can roll off the mesh at low tilt angles without any penetration. Besides overcoming the oil-fouling problem of many superhydrophilic coatings, this superhydrophilic and underwater superoleophobic mesh can be used to separate oil and water. The simple method used here to prepare the organic–inorganic hybrid coatings successfully produced controllable micro-nano binary roughness and also achieved a rough topography of micro-nano binary structure by controlling the content of inorganic particles. The mechanism of oil–water separation by the superhydrophilic and superoleophobic membrane is rationalized by considering capillary mechanics. Tetraethyl orathosilicate (TEOS) as a base was used to prepare the nano-SiO2 solution as a nano-dopant through a sol-gel process, while polyvinyl alcohol (PVA) was used as the film binder and glutaraldehyde as the cross-linking agent; the mixture was dip-coated on the surface of 300-mesh stainless steel mesh to form superhydrophilic and underwater superoleophobic film. Properties of nano-SiO2 represented by infrared spectroscopy and surface topography of the film observed under scanning electron microscope (SEM) indicated that the film surface had a coarse micro–nano binary structure; the effect of nano-SiO2 doping amount on the film’s surface topography and the effect of such surface topography on hydrophilicity of the film were studied; contact angle of water on such surface was tested as 0° by the surface contact angle tester and spread quickly; the underwater contact angle to oil was 158°, showing superhydrophilic and underwater superoleophobic properties. The effect of the dosing amount of cross-linking agent to the waterproof swelling property and the permeate flux of the film were studied; the oil–water separation effect of the film to oil–water suspension and oil–water emulsion was studied too, and in both cases the separation efficiency reached 99%, which finally reduced the oil content to be lower than 50 mg/L. The effect of filtration times to permeate flux was studied, and it was found that the more hydrophilic the film was, the stronger the stain resistance would be, and the permeate flux would gradually decrease along with the increase of filtration times.

Cu2ZnSnS4(CZTS) is a promising semiconductor material for photovoltaic applications,with excellent optical and electronic properties while boasting a nontoxic, inexpensive, andabundant elemental composition. Previous high‐quality CZTS thin films often required eithervacuum‐based deposition processes or the use of organic ligands/solvents for ink formulation,which are associated with various issues regarding performance or economic feasibility. To addressthese issues, an alternative method for depositing CZTS thin films using an aqueous‐basednanoparticle suspension is demonstrated in this work. Nanoparticles of constituent binary sulfides(CuxS and ZnS) are stabilized in an ink using tin(IV)‐based, metal chalcogenide complexes such as[Sn2S6]4‐. This research paper provides a systematic study of the nanoparticle synthesis and inkformulation via the enabling role of the tin chalcogenide complexing power, the deposition of highqualityCZTS thin films via spin coating and annealing under sulfur vapor atmosphere, theirstructural characterization in terms of nanocrystal phase, morphology, microstructure, anddensification, and their resultant optoelectronic properties.

In this study, water is apprehended as conventional fluid with the suspension of two types of hybrid nanoparticles, namely, single-walled CNTs (SWCNTs) and multiwalled CNTs (MWCNTs). The influence of a magnetic field, thermal radiation, and activation energy with binary chemical reaction has been added to better examine the fine point of hybrid nanofluid flow. The mathematical structure regarding the physical model for hybrid nanofluid is established and then the similarity variables are induced to transmute the leading PDEs into nonlinear ODEs. These equations were solved using the shooting technique together with RKF 4-5th order for various values of the governing parameters numerically. The results of prominent parameters were manifested through graphs and tables. The results indicate that the hybrid nanofluid SWCNT − MWCNT / water is fully adequate in cooling and heating compared to other hybrid nanofluids. In addition, the rise in the value of activation energy E upsurges the nanoparticle transfer rate of hybrid nanofluid.

Cefixime; widely employed cephalosporin antibiotic is unfortunately coupled to poor water solubility with resultant low oral bioavailability issues. To solve this problem micro-emulsion technique was used to fabricate binary SLNs using blend of solid and liquid lipids, surfactant as well as co-surfactant. The optimized nano suspension was characterized followed by modification to solidified dosage form. During characterization, optimized nano-suspension (CFX-4) produced particle size 189±2.1 nm with PDI 0.310±0.02 as well as −33.9±2 mV zeta potential. Scanning electron microscopy (SEM) presented nearly identical and spherical shaped particles. Differential scanning calorimetry and X-ray powder diffraction analysis ascertained decrease in drug’s crystallinity. In-vitro release of drug pursued zero-order characteristics and demonstrated non-fickian pattern of diffusion. The freeze dried nano suspension (CFX-4) was transformed to capsule dosage form to perform comparison based In-Vivo studies. In-Vivo evaluation corresponded to 2.20-fold and 2.11-fold enhancement in relative bioavailability of CFX nano-formulation (CFX-4) as well as the prepared capsules respectively in contrast to the commercialized product (Cefiget®). In general; the obtained results substantiated superior oral bioavailability along with sustained pattern of drug release for CFX loaded binary nano particles. Thus, binary SLNs could be employed as a resourceful drug carrier for oral CFX delivery.
