Oral administration of ionic drugs generally encounters with significant fluctuation in plasma concentration due to the large variation of pH value in the gastrointestinal tract and the pH-dependent solubility of ionic drugs. Polymeric complex micelles with charged channels on the surface provided us with an effective…
With the ITER project now well under way, the countries engaged in fusion research are planning, with renewed intensity, the research and major facilities needed to develop the science and technology for harnessing fusion energy. The Workshop on MFE Roadmapping in the ITER Era was organized to provide a timely forum f…
Soy protein isolate (SPI)–based cast films were incorporated with eugenol and isoeugenol. The release of eugenol and isoeugenol from the SPI films into simulated fatty food (olive oil) at 5°C, 20°C, 40°C and 60°C was determined by high performance liquid chromatography (HPLC) to investigate the effect of temperature o…
Photoconductive gain and normalized gain, which determine the device and material properties on photoconduction, respectively, have been defined for single-crystalline titanium dioxide (TiO2) nanorods (NRs) with various diameter sizes. The gain values of the NR photodetectors can reach 105 easily at a low bias of 0.1…
CaCu 3 Ti 4 O 12 ( CCTO ) was prepared by a conventional synthesis ( CS ) and through reaction sintering, in which synthesis and sintering of the material take place in one single step. The microstructure and the dielectric properties of CCTO have been studied by XRD , FE ‐ SEM , EDS , AFM , and impedance spectroscopy…
We report the three-dimensional electronic structure of iron pnictide superconductor LiFeAs obtained by polarization-dependent angle-resolved photoemission spectroscopy. The obtained orbital characters of each Fermi surface (FS) as well as the band dispersions were qualitatively consistent with those derived from loca…
ZnO-based junction field-effect transistors were fabricated by pulsed-laser deposition using room-temperature-deposited amorphous p-type ZnCo2O4as heterojunction gate on top of a n-ZnO channel layer. A channel mobility of 8.4 cm2/(Vs), current on/off ratio of 1.3 ×107, and a subthreshold swing of 91 mV/dec were achiev…
We have formed noncovalent inclusion compounds (ICs) between guest poly(ε-caprolactone) (PCL) chains, with molecular weights ranging from ∼2000 to 80 000 g/mol, and host urea (U). Upon careful removal of the U host, each of the guest PCL chains were coalesced from their U-IC crystals to produce coalesced samples (c-PC…
The mixed-valence manganite Sr${}_{0.65}$Pr${}_{0.35}$MnO${}_{3}$ has been prepared and its crystal and magnetic structure investigated between 7 and 1200 K using high-resolution powder neutron diffraction. The structural and lattice parameter data have been used to determine the octahedral tilting and spontaneous str…
Hydrogen isotope inventory (HII) is a key issue for fusion devices such as ITER. Simultaneous use of Be, W and C as the wall material for different parts of plasma-facing components (PFCs) will bring in material mixing issues, which compound that of hydrogen isotope retention. To simulate the hydrogen inventory in the…
Abstract A novel catalyst‐free synthetic strategy for producing high‐quality CdTe nanowires in solution is proposed. A special reaction condition is intentionally constructed in the reaction system to induce the formation of nanowires through oriented in situ assembly of tiny particles. To establish such special synth…
The systematic control over surface chemistry is a long-standing challenge in biomedical and nanotechnological applications for graphitic materials. As a novel approach, we utilize graphite-binding dodecapeptides that self-assemble into dense domains to form monolayer-thick long-range-ordered films on graphite. Specif…
While transition metal oxides have been thoroughly investigated as coatings for electrochemical capacitors due to their pseudocapacitance, little work has been done investigating other oxide coatings. There exists a whole class of nanoporous oxides typically synthesized by sol-gel chemistry techniques that have very h…
The develpoment of a highly selective immobilization strategy for the self-assembly of quantum dots (QDs) from solution on lithographically defined, biochemically functionalized metal nanopatterns is presented. Nanosale control is achieved for the formation of predominantly single-particle structures consisting of a Q…
Graphene has recently attracted wide-spread attention because of its unique transport and physical properties that are appealing for a wide range of electronic applications. Integration with scalable high-κ dielectrics is important for the realization of graphene-based top-gated electronic devices, including next gene…
In vitro and in vivo bioimaging, Yb/Tm doped fluoride nanocrystals (NCs) as nanoprobes have attracted much attention due to their near infrared (NIR) upconversion (UC) emission at 800 nm under NIR 980 nm excitation. Our paper presents a simple and general method which can further improve the intensity of NIR 800 nm em…
Green synthesis of protein stabilized silver nanoparticles (AgNPs) using the supernatant of a marine isolate, Pseudomonas fluorescens PMMD3 ( P.fluorescens ), and its biomedical applications and biocompatibility when coated on polycaprolactam is reported here. The AgNPs are spherical and are 1–10 nm in size. AgNP-coat…
A free-space broadband carpet-cloak, designed based on transformations optics and quasi-conformal mapping, was realized with all-dielectric gradient index rod-connected diamond-structured photonic crystals (PCs) in metamaterial regime. Complex three-dimensional sample with smooth continuous changing unit cells was fab…
Quantum dot (QD)-encoded microspheres play an important role in suspension arrays by acting as supports for various reactions between biomolecules. With regard to QD-encoded microspheres utilized in suspension arrays, three key requirements are controllable size, abundant surface functional groups, and especially exce…
