The decarboxylation of brown grease (BG) to green diesel hydrocarbons over a 5 wt % Pd/C catalyst was investigated in semibatch and batch reactors. Catalytic deoxygenation of BG under H 2 –Ar occurs primarily via decarboxylation with the liquid products of primarily n -heptadecane and n -pentadecane. A 90% conversion…
The spatial switching of mid-infrared light near-fields is proposed in coupled graphene heterogeneous ribbon pairs. By using the coupled plasmon modes in graphene ribbon pairs, the electric near-field enhancement can be spatially controlled in graphene ribbons as the tuning of the external bias voltage difference. Mor…
To overcome the limitations of the conventional particle size reduction technologies, a novel combinative particle size reduction method for the effective production of homogeneous nanosuspensions was investigated. Ursodeoxycholic acid, a poorly soluble drug representative, was tried to prepare nanosuspension by homog…
We report enhanced solar cell performance using high-density InAs quantum dots. The high-density quantum dot was grown by antimony mediated molecular beam epitaxy. In-plane quantum dot density over 1 × 1011 cm−2 was achieved by applying a few monolayers of antimony on the GaAs surface prior to quantum dot growth. The…
Thin film capacitors on areas up to 6 mm2 have been measured regarding capacitance density, relative permittivity, and electrical breakdown. The maximum storable energy density of the thin film capacitors will be discussed as a parameter to evaluate the thin film capacitors applicability. Therefore the measurements of…
Diazadithia[7]helicenes were synthesized from the readily available building block ethyl 7-chloro-8-formylthieno[3,2-f]quinoline-2-carboxylate by a Wittig reaction-photocyclization strategy. The helicene core was functionalized by nucleophilic aromatic substitution with a variety of nucleophiles (e.g., O-, N-, and C-c…
A systematic study is conducted to reveal how far the polymeric vesicle wall can embed gold nanoparticles (AuNPs) with different sizes by combining experiments and self-consistent field simulations. Both the experimental and simulative results indicate that the location of AuNPs in vesicle wall or in spherical micelle…
An unusually large Kadowaki–Woods ratio of A/γ2 ∼ 43 μΩ·cm·mol2·K2·J−2 has been observed for intermetallic Mn1-xFexCoGe compounds in the proximity of x = 0.2 where the magnetic state of itinerant electrons system changes. The ratio is approximately four times larger than observed for heavy fermion systems. The manifes…
The rheological model, Huet model, which is composed of one spring and two power function elements, has two expressions: one in time domain, which is used for creep compliance, and one in the frequency domain, which is associated with complex modulus. Previous research efforts showed that the Huet model provides a ver…
This study investigates encapsulation efficiency of model drug, encapsulated by magnetic poly d,l-lactic-co-glycolic acid (PLGA) nanoparticles (NPs). This is the following part of our preceding paper, which is referred in this paper as Part I. Magnetic nanoparticles and model drug human serum albumin (HSA)-loaded PLGA…
The nanocomposite of TiO2-MWCNTs has been synthesised by simple hydrothermal route showing significant enhancement in the photocatalytic activity for the degradation of methyl orange dye (MO). Several characterisations employed were X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy-dispersive X-ray s…
BACKGROUND: We have previously proposed triosephosphate isomerase of Giardia lamblia (GlTIM) as a target for rational drug design against giardiasis, one of the most common parasitic infections in humans. Since the enzyme exists in the parasite and the host, selective inhibition is a major challenge because essential…
Docyanine green (ICG) and LHRH-PE40 fusion protein are tethered onto drug carriers of silica nanorattles for imaging-guided tumor-specific drug delivery and bimodal therapy. The synergistic therapeutic effect of toxin PE40 and the chemotherapeutic drug docetaxel (Dtxl), specifically directed by LHRH to cancer, improve…
This letter reports microwave-assisted magnetization reversal (MAMR) in a 700-Gbit/in2 perpendicular media sample. The microwave fields were applied by placing a coplanar waveguide on the media sample and feeding it with narrow microwave pulses. The switching states of the media grains were measured by magnetic force…
We report significantly improved photosynthesis system based on AlGaN/GaN photochemical process. The resultant energy conversion efficiency is 0.13% which is the same level as that of real plants. The capability of this system is enhanced by high cathode potential due to the reduction of energy loss while utilizing th…
This paper reviews the physical characteristics of lunar dust and the effects of various fundamental forces acting on dust particles on surfaces in a lunar environment. There are transport forces and adhesion forces after contact. Mechanical forces (i.e., from rover wheels, astronaut boots and rocket engine blast) and…
We report a study on the Eu luminescence properties of Eu-doped GaN grown on a GaN substrate by organometallic vapor phase epitaxy. The site-selective excitation of Eu ions revealed the concentration of each luminescent site using the luminescence properties under resonant excitation. The quantitative evaluation of th…
This paper sets forth a method to obtain scaling laws for low-frequency power magnetic devices using normalized magnetic equivalent circuits. The resulting scaling laws are meant to facilitate the system-level design. While the method is presented in general, it is demonstrated using an inductor as an example. The pre…
We present an analysis of the photoluminescence (PL) properties of nanostructured titania (TiO2) thin films produced by femtosecond pulsed laser deposition. Up to four PL bands are evidenced and analyzed, corresponding to radiative transitions ranging from the blue/violet to the near-infrared. The PL analysis was carr…
The most serious problem associated with 193 nm lithography using ArF photoresists is the formation of roughness on photoresist film during plasma processes. The main determining factor for the formation of roughness during plasma etching is a chemical reaction between the photoresist polymer and reactive species from…
