Despite great advances in the field of organic semiconductors, especially regarding charge carrier mobility, most fabrication processes still involve toxic organic solvents. Aqueous colloids of polymeric semiconducting nanoparticles may be good alternatives to address this environmental issue. Here, we demonstrate the…
In this paper, a series of Wx/Ag/Al2O3 catalysts with different tungsten contents (0, 0.04, 0.06, 0.08, and 0.10 g/g) and 0.03 g/g silver for selective catalytic reduction of NO with methanol under excess oxygen (methanol‐SCR), were prepared with a traditional impregnation method. At a gas hourly space velocity (GHSV)…
The sphere impacting on the thin wall is simulated with node-separation finite element method, and investigations of the projectile fragmentation initiation threshold are processed based on the numerical results. The bumper-thickness-to-projectile-diameter ratio ( t/ D) is found to be the main determinant of the veloc…
Bubbles have been formed from solutions of 1-palmitoyl-2-oleoyl- sn -glycero-3-phosphocholine (POPC) in formamide. The bubbles were transferred onto a hydrophobic substrate after drainage time of 0–20 min. Drainage time of 20 min is sufficient to generate fully drained bubbles. The structure of the transferred films w…
Ordering of interpolated Ba(2+) chains and alternate Ta-O rows (TaO)(3+) in the pentagonal tunnels of tetragonal tungsten bronzes (TTB) is controlled by the nonstoichiometry in the highly nonstoichiometric Ba0.5-xTaO3-x system. In Ba0.22TaO2.72, the filling of Ba(2+) and (TaO)(3+) groups is partially ordered along the…
In this paper, rice husk (RH) and multi-walled carbon nanotubes (MWCNTs) composite have been fabricated as single layer microwave absorber. The MWCNTs with various weight ratio composites with RH have been prepared. Three different weight ratio 3 wt% MWCNTs, 5 wt% MWCNTs, and 15 wt% MWCNTs of the RH-CNTs have been des…
ABSTRACT The aim of this study is to fabricate polymer/hydroxyapatite (HA) particle composite fibers for drug encapsulation and sustained release. Firstly, drug‐loaded hydroxyapatite particles are synthesized in one step, then by electrospinning of the blends of drug‐loaded hydroxyapatite particles and polymer solutio…
By high‐throughput screening Fe–Sn–Cr, (Fe,Cr)3Sn2 (Fe53.5Cr6.5Sn40) with high potential as new hard magnetic compound is discovered. To produce the compound in large amounts a special procedure is needed. By quantitative microscopy and magnetometry promising intrinsic properties, Js ∼ 0.9 T, K1 ∼ 1.7 MJ/m3, TC ∼ 612…
Heterostructures of two-dimensional (2D) layered materials are increasingly being explored for electronics in order to potentially extend conventional transistor scaling and to exploit new device designs and architectures. Alloys form a key underpinning of any heterostructure device technology and therefore an underst…
Colloidal CuInS 2 nanocrystals are a promising alternative to toxic cadmium or lead chalcogenide nanocrystals that are widely studied as absorbing material in hybrid solar cells. Photovoltaic devices with colloidal CuInS 2 nanoparticles suffer, however, still from low performance. The present study focuses on a detail…
Since over 20 years it is known that riblet surfaces can reduce drag in fluids. The process by applying riblet paint in a single step by application, embossing and partial curing by UV-light is an alternative to bonded riblet foils for large area applications. The main advantage of this technique is the ability to pai…
In order to provide background for a review of stress corrosion cracking (SCC) in nuclear power plants, a review is first presented of the history of occurrence of SCC in fossil fired power plants and a few related applications. The historical development of SCC in nuclear power plants is then described. The many mate…
With the help of simulations we study the benefits of using coherent, phase-structured illumination to detect the overlay error in resist gratings fabricated by double patterning. Evaluating the intensity and phase distribution along the focused spot of a high numerical aperture microscope, the capability of detecting…
Peculiarities of X-ray diffraction from a rough surface at an extremely small grazing angle of an incident beam are theoretically studied. The interrelation of four diffraction channels (coherent reflectance, coherent transmittance, diffuse scattering in vacuum, and scattering into the matter depth) is analyzed for di…
Depending on the synthetic conditions (surfactant, acid, base, and presence or absence of TEOS), the sol–gel polymerization of functionalized polyorganosiloxane affords various textured silica-based materials.
Abstract Metal ion signaling in biology has been studied extensively with ortho‐nitrobenzyl photocages; however, the low quantum yields and other optical properties are not ideal for these applications. We describe the synthesis and characterization of NTAdeCage, the first member in a new class of Zn2+ photocages that…
Borneol, one of the commonly used Chinese medicines, can be used to treat many diseases. The main ingredient of natural borneol is d-borneol extracted from the volatile oil of dipterocarp trees. Numerous studies have proved the effectiveness of borneol. It has been widely used in relieving symptoms of anxiety, fatigue…

Chiral molecular crystals built up by chiral molecules without inversion centers have attracted much interest owing to their versatile functionalities related to optical, magnetic, and electrical properties. However, there is a difficulty in chiral crystal growth due to the lack of symmetry. Therefore, we made the mol…
The biodistribution of biodegradable nanoparticles can be difficult to quantify. We report a method using time resolved fluorescence (TRF) from a lanthanide chelate to minimize background autofluorescence and maximize the signal to noise ratio to detect biodegradable nanoparticle distribution in mice. Specifically, an…
