Advances in conducting polymers (CPs) have promoted the development of diabetic monitoring and treatment, which is of great significance in human healthcare and modern medicine. CPs are special polymers with physical and electrochemical features resembling metals, inorganic semiconductors and non-conducting polymers.…
Superhydrophilic surfaces have attracted attention from more and more fields. Here, based on superhydrophilic coatings, insulating substrates are made temporarily conductive and suited for electrostatic powder coating (EPC). Furthermore, by manipulating surface wettability of the substrate, epoxy‐polyester powder part…
The development of synthetic vascular grafts for coronary artery bypass is challenged by insufficient endothelialization, which increases the risk of thrombosis, and the lack of native cellular constituents, which favors pathological remodeling. Here, a bifunctional electrospun poly(ε-caprolactone) (PCL) scaffold with…
DEMO is the name for the first stage prototype fusion reactor considered to be the next step after ITER. For the realization of fusion energy especially materials questions pose a significant challenge already today. Advanced materials solution are under discussion in order to allow operation under reactor conditions…
White hybrid light‐emitting diodes (WHLEDs) are considered as a solid approach toward environmentally sustainable lighting sources that meet the “Green Photonics” requirements. Here, WHLEDs with protein‐based down‐converting coatings, i.e., Bio‐WHLEDs, are demonstrated and exhibit worthy white color quality, luminous…
Abstract Fe-based superconductors (FBS) present a large variety of compounds whose properties are affected to different extents by their crystal structures. Amongst them, theREFeAs(O,F) (RE1111,REbeing a rare-earth element) is the family with the highest critical temperatureTcbut also with a large anisotropy and Josep…
The applications of transition metal oxides as photovoltaic and photocatalytic materials are mainly impeded by their poor visible light absorption, low photogenerated carrier mobility, and low valence band position, which originate from the generally large band gap (≥3 eV), narrow transition metal d states, and deep o…
ABSTRACT Incorporating long chain branching (LCB) structure into biodegradable copolyesters can effectively improve their melt strength and film blowing processability. However, branching also results in deterioration of crystallizability which is also important for copolyester properties and processing. In this study…
A series of four tetra- or octacarbazolyl-substituted, tetraphenylmethane/-silane monomers have been oxidatively coupled into microporous polymer networks (MPNs). Chemical polymerization with iron(III) chloride gives bulk MPNs with BET surface areas ( S BET ) of up to 1331 m 2 g –1 (for the octacarbazolyl-substituted…
AIM: To design pluronic F68 (PF68)-conjugated polyamidoamine (PAMAM) dendrimer conjugates for doxorubicin (DOX) delivery for overcoming multidrug resistance, and clarify the reversal mechanism. MATERIALS & METHODS: A series of PAMAM-PF68 conjugates were designed. The antitumor activity of the DOX-loaded conjugates was…
Corrosion and scaling phenomena often appear simultaneously and act synergistically in geothermal water system. We prepared the nano-ZrO 2 –TiO 2 composite coatings on the AISI type 304 stainless steel with the chemical liquid phase deposition method. Surface morphology, crystal form, and chemical elements of the coat…
This paper aims to investigate the fractal characteristics of concrete fragments produced by impact fragmentation. The dynamic compressive tests for concretes with different static strengths were conducted by split Hopkinson pressure bar apparatus under various strain rates. The results indicate that the fragments siz…
Zinc oxide nanoparticles (ZnO-NPs) are among nanoscale materials displaying exponentially growing production due to their applications in the field of cosmetology, medicine, as antibacterial agent and catalyst. The ZnO nanomaterials release into the aquatic ecosystems through domestic and industrial wastewaters has th…
ABSTRACT Polyurethanes (PUs) were prepared by in situ polymerization of three diisocyanate with three synthesized low cost ester‐based polyols. The effect of diisocyanate type, diol structure, and molar ratio of diisocyanate to polyol on the mechanical properties was examined and the optimum chemical structure was int…
Abstract Sputter-deposited indium–tin oxide (ITO) electrodes became ohmic contacts for unintentionally doped β-Ga2O3(010) substrates with a carrier concentration of 2 × 1017 cm−3 after rapid thermal annealing in a wide range of annealing temperatures of 900–1150 °C. The formation of an ohmic contact is attributed to i…
Abstract Transition‐metal Group 5 vanadium dichalcogenides have shown promising properties for many applications, such as batteries, capacitors, electrocatalysts for hydrogen production and many more. However, their toxicological effects have not yet been well understood. Here, we studied the cytotoxicity of exfoliate…
Many buildings in Egypt e.g. museums, mosques and churches, do not possess controlled environments for minimizing the risks of damage of wooden artifacts due to the growth of fungi. Fungal damage usually appears as change in wood color, appearance of stains, and sometimes deformation of wooden surfaces. In this study…
The catalytic NH 3 combustion properties and local structures of copper oxides (CuO x ) supported on aluminum oxide borates (Al 20 B 4 O 36, 10Al 2 O 3 ·2B 2 O 3: 10A2B) were studied by means of high-angle annular dark-field scanning transmission electron microscopy, energy dispersive X-ray mapping, X-ray absorption f…
Low-cost TiB whiskers reinforced titanium matrix composite (TMCs) was fabricated with enhanced mechanical performances using in situ technologies and hot working. Morphologies observation indicates that needle-like TiB whiskers with a hexagonal transverse section grow along the [010] direction due to B27 crystal struc…
