It would be beneficial if the substrate surface were treated to have hydrophobic properties, in order to keep the line pattern fine during the inkjet processing, while at the same time having improved adhesion properties on the substrate. In this study, a polyimide surface was textured using atmospheric pressure plasm…
A hybrid organic-inorganic sol-gel coating with the addition of wollastonite particles is used as a potential solution to improve performance of low cost AISI 316L stainless steel. This work is focused on characterising the coatings by studying their synthesis and deposition, electrochemical, and in vitro and in vivo…
An analytical expression of Coulomb interaction between a sphere and a cylindrical rod was derived. Along with a recently reported van der Waals interaction expression, the derived Coulomb interaction expression, for the first time, allows one to quantitatively evaluate the activation energy in the oriented attachment…
In this study we synthesized a series of well-defined brush polymers, poly(oxy(11-(3-sulfonylpropyltrimethylglycinyl)undecylesterthiomethyl)ethylene-co-oxy(n-dodecylthiomethyl)-ethylene)s (PECH-DMAPSm, where m is the mol% of DMAPS (sulfobetaine) end group). The thermal properties and phase transitions of these polymer…
We demonstrate the first investigation of highly branched small-molecular organic microcrystals via self-organization of crystallites at the nucleation stage and then growth kinetics manipulation at the crystal growth stage. Temperature control was found to be critical in the formation of the branched structures. At h…
To study the effect of nanoscale titanium dioxide (TiO(2)) on cell responses, we synthesized four modifications of the TiO(2) (amorphous, anatase, brookite, and rutile) capable of keeping their physicochemical characteristics in a cell culture medium. The modifications of nanoscale TiO(2) were obtained by hydrolysis o…
Nanoporous Cu powders have been fabricated through mechanical alloying and subsequent dealloying. The ligament/channel size of as small as 21.3 ± 2.7 nm has been obtained by dealloying as-milled Al–Cu powders in a NaOH solution at room temperature, and can be tuned by changing the dealloying temperature. The surface d…
Natural leathers processed from hides and skins of animals face major threat from synthetic leathers as an alternative material with comparable properties for most of the applications. As consumers are becoming increasingly aware of environmental issues, there is a need for ecofriendly biodegradable materials. Natural…
Water-blown rigid polyurethane (PU) foams were made from 0–50% soy-phosphate polyol (SPP) and 2–4% water as the blowing agent. The mechanical and thermal properties of these SPP-based PU foams (SPP PU foams) were investigated. SPP PU foams with higher water content had greater volume, lower density, and compressive st…
Quantum dot-hydrotalcite layered nanoplatforms were successfully prepared following a one-pot synthesis. The process is very fast and a priori delamination of hydrotalcite is not a prerequisite for the intercalation of quantum dots. The novel materials were extensively characterized by X-ray diffraction, thermogravime…
The electrocaloric effect (ECE) has recently become very attractive phenomenon due to its various potential applications, for example in heating or cooling devices of new generation which could be more efficient and environmentally friendly. Here a direct measurements of the ECE in thick films of 8/65/35 PLZT ceramics…
This study examined the formation of nanofiber hydrogels at neutral pH for 16 types of peptides with different net charges, hydrophobicities, and degrees of polymerization. The peptides formed various hydrogels depending on the arrangement of charged amino acids in the antiparallel β ‐sheet structure. Circular dichroi…
A new strategy was explored for the visual determination of Cu(2+) using copper-catalysed in situ formation of Ag nanoparticles. In this method, only common reagents were used and the pre-synthesis and modification of nanoparticles are avoided. Ag(+) can form a milk-white suspension (AgBr) with Br(-) in an aqueous sol…
A blue phase (BP*) liquid crystal mixture was stabilised via doping with three different types of colloidal particles, smaller hexane thiolate-capped gold nanoparticles (NP1) with a size around 2.2 nm, larger oleylamine capped gold nanoparticles (NP2) with an average size of 13.2 nm, and manganese oxide nanoparticles…
A new approach to manufacture of metallic-intermetallic laminate (MIL) composites is realized: explosive welding of a package of titanium and aluminum sheets with the subsequent sintering without a hydraulic press. Sheets of the titanium (thicknesses of 0.5 and 0.6 mm), aluminum (thickness of 1.0 mm) were used. Packag…
A generic in situ method for producing triple component hydrophobic inorganic–organic nanocomposite particles, using a combination of modified emulsion templating and freeze-drying, is presented. Model nanocomposite particles have been developed bearing up to three hydrophobic ingredients chosen from polystyrene, oil…
Porous‐structured nickel oxide (PsNiO) was obtained through the oxidization of a nickel thin film. The nickel thin film was deposited using the pulsed laser deposition (PLD) method on a nickel foil as a substrate. The results show uniform PsNiO after the oxidization of the nickel thin film at 750 ∘ C for 1 h. X‐ray di…
This study presents the composites prepared by melt blending based on high-density polyethylene, containing various amounts of kenaf fiber loadings and polyethylene-grafted maleic anhydride (PE-g-MA) in an internal mixer were prepared and investigated. Fourier transform infrared spectroscopy was used to characterize b…
Regioselectively brominated BODIPYs were shown to undergo nucleophilic substitution and Sonogashira coupling reactions with a one-pot procedure, yielding diversely substituted fluorophores.
Monodisperse closed-pore silica spheres with small pore diameters have been prepared through a simple self-assembly approach. The closed-pore silica spheres were synthesized in near neutral conditions, using cetyltrimethyl ammonium bromide (C16TAB) as a template. The products show a spherical morphology with a uniform…
