Abstract Mixed‐matrix membranes (MMMs) consisting of ethyl cellulose as continuous matrix and inorganic particle C60 as dispersed phase were prepared for propylene/propane separation. The impact of the C60 content on the separation properties of MMMs without and with ultraviolet cross‐linking was investigated. The inc…
We report a joint theoretical and experimental investigation on the effect of TiO 2 protonation on the interfacial electronic coupling and injection rates in organic dye-sensitized solar cells (DSCs). We model the electronic structure of different organic dye-sensitized TiO 2 cluster models at different degrees of sur…
Abstract Metal nanowires supporting propagating surface plasmons (SPs) can be used as nanowaveguides and nanoantennas for light manipulation beyond the diffraction limit. Here the control of the propagation and radiation of SPs on silver nanowires is investigated. By covering an Al2O3 layer onto a silver nanowire to c…
A C60 Prato derivative with bis-(t)Bu ester was prepared as a stable and convenient scaffold for the development of fullerene derivatives such as water-soluble C60-PEG conjugates, fulleropeptides via solid phase synthesis, and bis-functionalized C60.
In this work, we have synthesized two different phases of CdS nanoparticles, CdS/TiO2 composites and their supported form on ZSM-5 type metalosilicates (ferrisilicate and aluminosilicate) as CdS–TiO2/metalosilicate composites. The photocatalytic performance of these samples was evaluated by monitoring the amount of hy…
Golden single-walled carbon nanotubes (SWNTs) were prepared by growing gold nanoparticles onto the bilayer polysaccharide functionalized SWNTs. The layer-by-layer self-assembly of sodium alginate and chitosan on SWNTs provided an ideal surface with high density of active metal-binding groups such as amino and carboxyl…
This report investigates the impact of droplet temperature on the head-on collision of binary droplets on a superhydrophobic surface. Understanding droplet collision is critical to many fundamental processes and industrial applications. There are many factors, including collision speed, collision angle, and droplet co…
Twinning induced plasticity (TWIP) steels with excellent strength and elongation properties are expected to be the next generation of automotive high-strength steels. The present work investigates endogenous inclusions formed in Fe–25Mn–3Si–3Al TWIP steels in laboratorial ingot, mold casting after AOD steelmaking and…
Cu-poor Cu2− x SnS3 (CTS) powders with x = 0.0–0.3 prepared by mixing the elemental powders and post-heating at 600 °C in N2 gas were analyzed by X-ray diffraction and ultraviolet–visible–near-infrared (UV–vis–NIR) spectroscopy. The area of the solid solution region in the Cu-poor side of CTS was quite small in the Cu…
Current theoretical studies of electronic correlations in transition metal oxides typically only account for the local repulsion between d -electrons even if oxygen ligand p -states are an explicit part of the effective Hamiltonian. Interatomic interactions such as between d - and (ligand) p -electrons, as well as the…
Mn1.4Co1.0Ni0.6O4 (MCN) thin films are prepared by RF sputtering deposition method on amorphous Al2O3 substrate. Microstructure and X-ray photoelectron spectroscopy analyses suggest improvements in crystallinity and stoichiometry for MCN films with post-annealed process. Infrared (IR) optical constants of the MCN film…
Microfluidic platform for the synthesis of complex nanocapsules is presented via a controlled self-assembly. The monodisperse nanocapsules in the range of 50-200 nm consist of a dendritic polyethylene core and a Pluronic copolymer shell. The resultant nanocarriers encapsulate large amount of hydrophobic anticancer dru…
LED lighting has been a strongly growing field for the last decade. The outstanding features of LED, like compactness and low operating temperature take the control of light distributions to a new level. Key for this is the development of sophisticated optical elements that distribute the light as intended. The optics…
The lipidic mesophase or in meso method for crystallizing membrane proteins has several high profile targets to its credit and is growing in popularity. Despite its success, the method is in its infancy as far as rational crystallogenesis is concerned. Consequently, significant time, effort, and resources are still re…
Carbon nanotubes (CNTs) have promised a range of applications in biomedicine. Although influenced by the dispersants used, CNTs are recognized by the innate immune system, predominantly by the classical pathway of the complement system. Here, we confirm that complement activation by the CNT used continues up to C3 and…
Supramolecular interactions based on porphyrin and fullerene derivatives were successfully adopted to improve the photovoltaic performance of p-type dye-sensitized solar cells (DSCs). Photoelectron spectroscopy (PES) measurements suggest a change in binding configuration of ZnTCPP after co-sensitization with C60PPy, w…
We measure gate-tuned thermoelectric power of mechanically exfoliated Bi2Se3 thin films in the topological insulator regime. The sign of the thermoelectric power changes across the charge neutrality point as the majority carrier type switches from electron to hole, consistent with the ambipolar electric field effect o…
This study is aimed to investigate the applicability of poloxamer 407 (P407) and 188 (P188)-based temperature-sensitive in situ hydrogel (TSHG) in sustained delivery of hydrophilic macromolecules following intramuscular administration. Polyethylene glycols (PEGs) with molecular weight of 5-, 20-, and 40-kDa were used…
Coarse-grained models are becoming increasingly popular due to their ability to access time and length scales that are prohibitively expensive with atomistic models. However, as a result of decreasing the degrees of freedom, coarse-grained models often have diminished accuracy, representability, and transferability co…
Unwanted adhesion of microalgae on submerged surfaces is a ubiquitous problem across many maritime operations. We explored the strategy of developing a silver nanoparticle (AgNP) coating for antifouling applications in marine and freshwater environments. In situ growth of AgNPs was achieved by a polydopamine (PDA)-bas…
