The structural profiles and electronic properties of pentacene (C 22 H 14 ) multilayers on Ag(111) surface has been studied within the density functional theory framework. We have performed first-principle total energy calculations based on the projector-augmented wave method to investigate the initial growth patterns…
Self-consistent, mean-field description of charge injection into a dielectric medium is modified to account for discreteness of charge carriers. The improved scheme includes both the Schottky barrier lowering due to the individual image charge and the barrier change due to the field penetration into the injecting elec…
We compute the electrical conductivity for liquid hydrogen at high pressure using quantum Monte Carlo. The method uses Coupled Electron-Ion Monte Carlo to generate configurations of liquid hydrogen. For each configuration correlated sampling of electrons is performed in order to calculate a set of lowest many-body eig…
We consider two spherical, roughened crystals with approximately isotropic surface free energy which are brought into contact and begin to sinter. We argue that the geometry immediately post-contact is two dimensional and Cartesian and can be approximated by the evolution of a slot-shaped cavity. On this basis, we con…
While the melting of crystals is in general not understood in detail on a microscopic scale, there is a microscopic theory for a class of two-dimensional crystals, which is based on the formation and unbinding of topological defects. Herein, we review experimental work on a colloidal two-dimensional model system with…
Multifunctional nanocarriers based on chitosan/gold nanorod (CS-AuNR) hybrid nanospheres have been successfully fabricated by a simple nonsolvent-aided counterion complexation method. Anticancer drug cisplatin was subsequently loaded into the obtained hybrid nanospheres, utilizing the loading space provided by the chi…
We have found that the hybrid organic-inorganic perovskite-like formate Mn(HCOO)(3)[(CH(3))(2)NH(2)] shows a dielectric transition around 190 K. According to single crystal X-ray diffraction, the compound shows rhombohedral symmetry at room temperature and monoclinic symmetry at low temperature (100 K), and the main d…
A new approach for synthesis of high quality core/shell nanocrystals, “thermal-cycling coupled single precursor” (TC-SP), was developed. It was applied for the synthesis of high efficiency, good color purity, nearly monodisperse, alloying-free, and stable CdS/ZnS core/shell nanocrystals with their emission peak tunabl…
We report the first NMR investigation of spin dynamics in the overdoped nonsuperconducting regime of $\mathrm{Ba}({\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}{)}_{2}{\mathrm{As}}_{2}$ up to $x=0.26$. We demonstrate that the absence of interband transitions with large momentum transfer ${\mathbf{Q}}_{\mathrm{AF}}\…
Scanning tunneling microscopy and photoemission spectroscopy have been used to determine the origin of the band-gap state in rutile TiO2(110). This state has long been attributed to oxygen vacancies (O{b} vac). However, recently an alternative origin has been suggested, namely, subsurface interstitial Ti species. Here…
Plasma was generated in organic solvents (ethanol-hexane mixture) in order to coating inside a narrow tube.The discharge feature was examined with oscilloscope.The deposited films were characterized with FTIR.We introduce the recent results in this presentation.
Significance The authors report the synthesis of three different copolymers incorporating benzodisdioxole units. By constraining the alkoxy units, the authors show a large Stokes shift in the resulting donor-acceptor copolymers.
Protein-peptide and protein-protein interactions involving Src homology domains, studied using nuclear magnetic resonance spectroscopy and isothermal titration calorimetry.
Inner wall coating have been developed by using PVD and CVD hybrid methods to narrow tubes by the 2nd harmonic ECR micro plasma source.Here, we report on the evaluation result of the deposited carbon films by PECVD, PVD (coaxial sputtering) and hybrid methods for various gas composition ratios and gas pressures.
The study has aimed to remove the brass layer on fine wire by using plasma dry etchings. The discharge characteristics of newly developed line-shaped plasma and the effect of brass wire sputtering for various gas pressures are presented.
We review progress in developing epitaxial graphene as a material for carbon electronics. In particular, improvements in epitaxial graphene growth, interface control and the understanding of multilayer epitaxial graphene's electronic properties are discussed. Although graphene grown on both polar faces of SiC is addre…

Kemampuan matrik membasahi permukaan serta disebut wettability. Salah satu cara untuk mengetahui sifat mampu basah (wettability) adalah dengan cara uji sudut kontak (droplet). Pengukuran sudut kontak () adalah salah satu metode paling sederhana untuk menentukan kompatibilitas antarmuka antar dua permukaan di mana mer…
Nanocomposites are materials that comprise dispersion of nanometer-size particles in a (polymer/ceramic/metal) matrix. The polymers containing layered silicate clay minerals as reinforcing agent can be classified as intercalated or exfoliated depending on dispersing of clays in the matrix. Smectite (especially montmor…
Trial coating of nano-diamond on fine wire surface has been investigated by using the long-shaped quadrupole cylindrical magnetron plasmas.The results of deposited film quality evaluated by Raman spectra are reported for controlling the wire temperature.
