Stimuli-responsive drug delivery systems are highly desirable for improved therapeutic efficacy and minimized adverse effects of drugs. Mesoporous silica nanoparticles (MSNs) functionalized with pentadentate ligands, N-(3-trimethoxysilylpropyl)ethylenediamine triacetate (TSP-DATA), in the presence of metal ions with a…
Abstract A biodegradable alternative material to synthetic plastics was explored in this study through the extrusion of soy protein isolate (SPI) composite films containing soy cellulose microfibers (SMF). SMF were isolated from soy pods and stems using a chemo-mechanical method. The fibers produced through successive…
Natural calcium carbonate-based nanocomposites often have superior physical properties and provide a comprehensive source for bioinspired synthetic materials. Here we present thermodynamically stable, transparent CaCO3 microlens arrays (MLA) produced by transforming an amorphous CaCO3 phase into nanocrystalline calcit…
This study was conducted to investigate the effect of multilayer protective clothing on heat and moisture transport under various ambient conditions. By using the Human-Clothing-Environment simulator, a four-layered clothing system was exposed to a high rate of sweat pulse for a duration of 3 hours in seven different…
Block copolymer/lithium salt mixtures are promising materials for lithium battery electrolytes. The growth of ordered lamellar grains after a block copolymer electrolyte was quenched from the disordered state to the ordered state was studied by depolarized light scattering. Three quench depths below the order-to-disor…
Trapping of interstitial atoms by foreign substitutional atoms is a phenomenon that significantly influences the chemistry of the system as well as the diffusivity of the interstitial components. In their previous paper (Svoboda et al 2013 Modelling Simul. Mater. Sci. Eng. 21 065012), the present authors determined th…
Abstract One of the most commonly used vegetable oil plasticizer in polyvinyl chloride (PVC) is epoxidized soybean oil (ESBO). On the contrary, epoxidized palm oil is among the least used, because of its low compatibility with PVC. This work reports that epoxidized and esterified palm kernel oil (EEPKO) has the potent…
We have demonstrated that domain switching in ferroelectric copolymer films can be significantly affected by humidity. With increasing relative humidity (RH), we observed larger domains with highly irregular boundaries as a result of lateral spreading of the tip-induced electric field that originates from water adsorp…
The electronic structure and optical response of silicane to strain are investigated by employing first-principles calculations based on many-body perturbation theory. The bandgap can be efficiently engineered in a broad range and an indirect to direct bandgap transition is observed under a strain of 2.74%; the semico…
N 1 , N 1 ′‐(6‐methoxy‐1,3,5‐triazine‐2,4‐diyl)dibenzene‐1,4‐diamine (MTDA) containing triazine ring structure was synthesized and characterized. A new, montmorillonite (Mt) modified by MTDA (MTDA‐Mt), was prepared by ion‐exchange of sodium montmorillonite (Na + ‐Mt) with protonated form of MTDA. It was confirmed by F…
We report on a bistable light transmission through a bilayer “fish-scale” (meander-line) metamaterial. It is demonstrated that an all-optical switching may be achieved that is nearly the frequency of the high-quality-factor Fano-shaped trapped-mode resonance excitation. The nonlinear interaction of two c…
The electronic and magnetic properties of armchair edge MoS2 nanoribbons (MoS2-ANRs) underboth the external strain and transverse electric field (Et) have been systematically investigated by using the first-principles calculations. It is found that: (1) If no electric field is applied, an interesting structural phase…
This work presents the synthesis and characterizations of a stable and well-sinterable proton conductor BaCe 0.35 Zr 0.50 Y 0.15 O 3-δ in which a transition of conductivity occurred steeply from the order of 10 −3 to 10 −2 S cm −1 and activation energy changed from 0.35 to 0.22 eV in the temperature range from 350 to…
In order to improve the properties of electrodes based on carbon nanotubes (CNTs), nanocomposite electrodes of CNTs/activated carbon (AC) are prepared. The effect of CNT loadings on the performance of the nanocomposite electrodes is evaluated by electrochemical methods. Scanning electron microscopy images show the CNT…
Variable-wavelength photocurrent microscopy and photocurrent spectroscopy are used to study the photoresponse of (n, m) sorted single-walled carbon nanotube (SWNT) devices. The measurements of (n, m) pure SWCNT devices demonstrate the ability to study the wavelength-dependent photoresponse in situ in a device configur…
The precise measurement of conductivity of a semiconductor film such as polypyrrole (Ppy) should be carried out by the four-point probe method; however, this is difficult for classroom application. This article describes the development of a new, convenient, handmade conductivity device from inexpensive materials that…
The CMOS-compatible double-spacer lithography demonstrates a scalable approach to fabricate the tri-gate graphene nanoribbon (GNR) transistor with self-aligned side gates, controllable GNR width, and reduced variations in line-edge roughness and GNR width. The electrical characteristics show bandgap modulation with tr…
In this work, fully alpha-axis oriented SrTiO3 thin films were synthesized by ink-jet printing of water-based precursor inks. The developed precursor solution or 'ink' was optimized in terms of rheology, leading to the ejection of single droplets showing a maximum contact angle of 12 degrees on (100) oriented single c…
A facile colloidal approach to synthesize Ag8 (Ge1-x ,Snx )(S6-y ,Sey ) nanocrystals (NCs) in a highly controlled way across the entire compositional ranges (0≤x≤1, 0≤y≤6) has been developed. The NCs exhibit a uniform size distribution, highly crystalline structure, over 1 g scalable synthesis, and tunable band gaps i…
