In this work, we have successfully developed a novel multifunctional near-infrared (NIR)-stimulus controlled drug release system based on gold nanocages as photothermal cores, mesoporous silica shells as supporters to increase the anticancer drug loading and thermally responsive poly( N -isopropylacrylamide) (PNIPAM)…
Identifying cancer cells and quantifying cancer-related events in particular organelles in a rapid and sensitive fashion are important for early diagnosis and for studies on pathology and therapeutics of cancers. Herein a smart "off-on" cyclooxygenase-2-specific fluorescence probe (ANQ-IMC-6), able to report the prese…
The stacking orders in layered hexagonal boron nitride bulk and bilayers are studied using high-level ab initio theory [local second-order Møller-Plesset perturbation theory (LMP2)]. Our results show that both electrostatic and London dispersion interactions are responsible for interlayer distance and stacking order,…
Two-dimensional semiconductors are structurally ideal channel materials for the ultimate atomic electronics after silicon era. A long-standing puzzle is the low carrier mobility (μ) in them as compared with corresponding bulk structures, which constitutes the main hurdle for realizing high-performance devices. To addr…
Because of their heterogeneous nature, supported metal catalysts always contain metal centers in a rather broad dispersion range, and the presence of even atomically dispersed metals has been reported on oxide supports. The role of the atomically dispersed metal centers in the overall catalytic performances of these s…
Eu3+-doped Na2Ti6O13 (Na2Ti6O13:Eu) nanorods with diameters of 30 nm and lengths 400 nm were synthesized by hydrothermal and heat treatment methods. Raman spectra at ambient conditions indicated a pure monoclinic phase (space group C2/m) of the nanorods. The relations between structural and optical properties of Na2Ti…
Taphonomy is a tool used in palaeoenvironmental interpretations dating back to the process of palynomorphs deposition. The interpretation of taphonomic studies provides subsidies to the understanding of the environmental past conditions through the marks left on the preserved palynomorphs. The study area is located in…
A new concept of a beam bump for high current proton beams is presented. A beam dump prototype was built and tested with electron and proton beams up to 1.5 kW and 1 kW respectively. The tests demonstrated that the new concept satisfies the main requirements for the beam dump: acceptance of high beam intensity, low pr…
We propose a method for in-plane switching of vertically aligned negative liquid crystals (LCs) for high transmittance and wide viewing angle. By applying an in-plane electric field using a double-layered electrode structure, LC molecules can be rotated by the vertical as well as the in-plane components of the applied…
Self-assembly is a process in which components autonomously organized into structure without external direction. There are many researches of self-assembly system at molecular scale to macro scale. Such a self-assembly system may serve as the new production method with the characteristics, such as decomposability, sel…
Three series of nematogens with a terminal p-nitrophenyl group linked with biphenyl groups via flexible spacers were synthesised and their transitional properties were studied by means of differential scanning calorimetry (DSC) and polarising microscopy (POM). The nematic–isotropic transition temperature and the assoc…
The behavior of the layered Fe 3+ perovskite superstructure with composition Ba 1.7 Ca 2.4 Y 0.9 Fe 5 O 13 (BCYF) as an intermediate temperature solid oxide fuel cell (IT-SOFC) cathode is investigated by an integrated modeling, secondary ion mass spectroscopy (SIMS), processing, and electrochemistry approach. Electron…
Abstract A poly(4‐bromoaniline) (PBA) film is electrochemically synthesized on a gold electrode for the recognition of amino acids enantiomers. Scanning electron microscopy measurements show that the porous PBA films are made up of nano‐ribbons. At the PBA modified Au electrode differential pulse voltammograms of L ‐…
Poly(ethylene- co-vinyl acetate), acrylonitrile butadiene copolymer, and their blend (50/50 wt%) loaded with different concentrations of high-abrasion furnace were prepared. Mechanical, thermal, and electrical properties as well as the morphology and the swelling behavior have been investigated in view of filler loadi…
ABSTRACT The synergistic mechanism of tetrabutyl titanate (TBT) in the intumescent flame‐retardant polypropylene (PP) composites was investigated in this work. The intumescent flame‐retardant was composed of pentaerythritol (PER) as a carbonizing agent ammonium polyphosphate (APP) as a dehydrating agent and blowing ag…
Electrically‐active nanoporous membranes are prepared by coating the surface of anodized alumina with electroactive polymers using vapor phase polymerization with four combinations of conjugated polymers and doping ions: poly(3,4‐ethylenedioxythiophone) and polypyrrole, FeCl 3 and FeTs 3 . The permeability of the poly…
The calculation of the 3d-intrashell excitations in coordination compounds by means of the Effective Hamiltonian Crystal Field (EHCF) method is generalized to their polynuclear analogues to properly describe several open d-shells and their magnetic interactions. This challenge requires improving the precision of ca. 1…
A test set-up in intermediate scale was conceived to investigate the structural integrity of materials under fire. The task was to develop a realistic test scenario targeting component-like behaviour. Carbon-fibre-reinforced sandwich specimens (500 × 500 × 20 mm) were used to examine failure mechanisms, times to failu…
Prior to its use for microwave absorption, NiZn ferrite with certain compositions and with ultrafine microstructures (submicron/nanoscale) have been fabricated to investigate the best chemical composition and microstructure for such absorption. A mixture of iron oxide$({\rm Fe}_{2}{\rm O}_{3})$, nickel oxide (NiO) and…
Abstract Surface functionalization plays a crucial role in the design of biosensors. For this purpose, a novel functional monomer, 6‐(4,7‐bis(2,3‐dihydrothieno[3,4‐ b ][1,4]dioxin‐5‐yl)‐2 H ‐benzo[ d ][1,2,3]triazol‐2‐yl)hexan‐1‐amine (BEDOA‐6), was designed and synthesized. Poly(BEDOA‐6) was utilized as an immobiliza…
