AbstractIntroducing specific textures to titanium alloy implant surface is helpful to modify the surface properties of materials. In this article, biomedical TC4 (Ti ‐6Al‐4V) alloy was textured by a 10‐ps infrared laser. Laser parameters that directly affected the detailed dimension of textures and its characteristics were optimized within laser power, defocusing amount, and scanning parameters via response surface methodology. These textures consisted of groove array about 30–90 μm in depth and 100 μm in width were prepared and their surface property (including surface morphology, element c...

The microstructures of Sn-Ti/SiC interface were characterized by scanning electron microscopy, X-ray diffraction and transmission electron microscopy, and the mechanical properties of joints were evaluated by shear tes...

Maleic anhydride-modified PP (MAPP) with different weight fractions (wMA) of acid-modified groups was added as the compatibilizer. Two nanoscale aspects were examined: the degree of wetting of the compatibilizer on the microcrystalline cellulose (MCC) filler and the extent of compatibil...

Publication date: Available online 22 October 2019Source: Journal of Membrane ScienceAuthor(s): Paul Jacob, Baptiste Dejean, Stephanie Labori, Corinne CabassudAbstractThis paper describes the development of a new optical tool to detect in-situ wetting in membrane distillation. The principle of the detection tool is based on the phenomenon of light transmission. A dedicated experimental setup was developed. The proof of concept of this optical tool is validated using in parallel the Detection of Dissolved Tracer Intrusion (DDTI) method that was previously developed, and which is based on the detection of remaining salt trac...

In this study, chiral mesoporous silica nanoparticles (CMSN) and enlarged chiral mesoporous silica nanoparticles (E-CMSN) with a particle size from 200 to 300 nm were synthesized. Fourier transform infrared spectrometer (FTIR), circular dichroism spectrum, scanning electron microscopy (SEM), transmission electron microscope (TEM), and nitrogen adsorption/desorption measurement were adopted to explore their characteristics. The results showed that the surface area, pore volume, and pore diameter of E-CMSN were higher than those of CMSN due to enlarged mesopores. Poorly water-soluble drug nimesulide (NMS) was taken as the mo...

Herein we describe a method to functionalize textile surfaces using thin, open coatings based on natural wax particles and natural polymers rendering cellulosic fabrics water-repellent while retaining their feel and breathability. The impact of curing temperature, catio...

Publication date: Available online 13 September 2019Source: Materials Chemistry and PhysicsAuthor(s): Veereshgouda S. Naragund, P.K. PandaAbstractCellulose acetate (CA) nanofiber membrane was prepared by electrospinning method using solvent mixtures of methyl ethyl ketone (MEK) and N, N, - dimethylacetamide (DMAc) in different ratios (2:1, 1:1, 1:2) and also different concentration of CA (7-19%). MEK was selected in place of acetone due to its high boiling point, thereby, minimises the evaporation loss of the solvent enabling the longer duration of electrospinning. The morphology of electrospun nanofibers was observed by S...
