A stimuli-responsive poly(vinyl alcohol) (PVA)/sodium alginate (SA) blend monolith with nanoscale porous (mesoporous) structure is successfully fabricated by thermally impacted non-solvent induced phase separation (TINIPS) method. The PVA/SA blend monolith with different SA contents is conveniently fabricated in an aqueous methanol without any templates. The solvent suitable for the fabrication...

Tabular dunites in the Josephine peridotite of southwestern Oregon represent conduits for melt extraction from the upper mantle. The amount of melt trapped within these channels during cooling and exhumation of the peridotite massif was calculated using a mass-balance approach. These calculations suggest that no more than 0·1^0·2 vol. % melt could have been trapped within these dunites after cr...

Introduction: Impact melts resulting from craterproducing impacts on asteroids can be used to understand the collisional evolution of our solar system. Part of that analysis includes an assessment of the cooling rates of the impact melts and/or the locations where the melts are deposited. In this study, we examined LAP 04751 [1], which is an impact melt breccia that came from the H-chondrite pa...

Hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. Today this technology has found its place in the array of pharmaceutical manufacturing operations. Melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

It has long been recognised that at elevated temperatures surface energy is the driving force for the distribution of melts and fluids among crystalline grains. While for ideal isotropic systems only two parameters, the dihedral angle (the ratio of grain boundary energy to solid-liquid surface energy) and the melt fraction are needed to completely constrain the melt distribution, anisotropic sy...

Melt electrowriting, a high-resolution additive manufacturing technique, is used in this study to process magnetic polymer-based blend for the first time. Carbonyl iron (CI) particles homogenously distribute into poly(vinylidene fluoride) (PVDF) melts result well-defined, highly porous structures or scaffolds comprised of fibers ranging from 30 50 µm diameter. This observes that CI particle inc...

Halloysite nanotubes (HNTs) were incorporated into an EPDM/SBR rubber/styrene-butadiene rubber (SBR) composite by melt blending of HNTs the blend. The mechanical properties, abrasion and swelling resistance ranging from 2 parts per hundred (phr) to 10 investigated in base rubber. Tensile strength, 100% modulus (modulus at elongation), elongation break tear strength evaluated ambient temperature...

BACKGROUND/AIMS High viscosity silicone oils are used as tamponade agents to increase the resistance to emulsification; however, this makes the oils more difficult to inject. Increasing the extensional viscosity is one way to reduce emulsification. This study aimed to evaluate how silicone oils with increased extensional viscosity behave in terms of their ease of injection. METHODS The shear ...
