The interaction of exposure radiation with amorphous solid films of resists and their constituents leads to distinct photophysical and photochemical processes that in turn underlie the basis of the contrast between the exposed and the unexposed sections of the resist film. A short section of this chapter is therefore…
采用密度泛函理论方法（DFT）,对三联吡啶铂（Ⅱ）配合物的结构与电子光谱进行了系统研究.筛选的PBE/LanL2DZ（6-311＋G（d））—BMK/LanL2DZ（6-31＋G（d））方法,计算结果能较好地与实验值吻合：对光谱峰波长的计算,吸收光谱和发射光谱平均误差分别为14 nm和17 nm.通过对前线分子轨道的分析,归属了各光谱峰的跃迁类型.计算结果表明,不同推拉电子效应的取代基对配合物光谱峰的位置和跃迁类型具有较大影响,为已有的实验结论提供了有力的理论阐述.
Purpose: The use of high-field MRI scanners has introduced new challenges for cardiac imaging, associated with B1- and B0-field inhomogeneities. A dual – source RF transmission system may help reduce dielectric effects, thus improving image contrast and reducing local SAR peaks of cardiac TSE and SSFP sequences, there…
A new nickel zinc chromate with the composition of (NH 4 OH) 3/2 NiZn 2 Cr 2 O 9 ⋅2H 2 O was synthesized by hydrothermal method. The compound was characterized by XRD, TGA, and XRF. X-ray powder diffraction data show that the crystal system of the title compound is hexagonal with space group R -3 m , z =3, and unit-ce…

With the means of Schrodinger equation a two electron problem is considered. It is shown that electrons in a periodic potential might experience effective attraction without any mediating agents; which means electrons in HTSC might have effective attraction potential.
In the title complex, [Mn(C(10)H(6)O(7))(C(12)H(8)N(2))(2)(H(2)O)]·2H(2)O, the Mn(II) atom is coordinated by two O atoms from one 2-(3-carb-oxy-5-carboxyl-atophen-oxy)acetate (HOABDC(2-)) dianion and one water mol-ecule and by four N atoms from two 1,10-phenanthroline (phen) ligands within a distorted octa-hedral geom…
Improved material for use in organic photovoltaics (OPV) devices, also called polymer-solar cells (PSC), has been developed. Increased ordering of the active layer of bulk heterojunction (BHJ) cells has been achieved by the use of inert silica spheres in conjunction with suitable fullerene derivatives. Silica spheres…
This research was concerned about clothes production from remnant fabrics that can increase product value and meet market demand by using patchwork and applique technique. The research was conducted into 3 phases : data collecting, prototype production and consumer satisfaction evaluation. Questionnaires were used as…

Background: Arterial grafts such as right internal thoracic artery (RITA) and radial artery(RA) has been used as second graft with various configuration. The aim of this study was to compare the ar...
A general, efficient method is demonstrated for exchanging native oxyanionic ligands on inorganic nanocrystals with functional trimethylsilylated (TMS) chalcogenido ligands. In addition, newly synthesized TMS mixed chalcogenides leverage preferential reactivity of TMS-S bonds over TMS-O bonds, enabling efficient trans…
Vehicle emissions, arising from incomplete fuel combustion and reactions between N2 and O2 leading to NOX, have detrimental effects on human health and environment quality. Engine exhaust contains a variety of regulated components, such as hydrocarbons, CO, nitrogen oxides (NOX), and particulate matter (PM). Governmen…
Electron capture dissociation mass spectrometry data provide information about the three-dimensional structure of the three-helix bundle protein KIX. In their Communication on page 873 ff., K. Breuker and co-workers report on the stabilization of the protein by electrostatic interactions after transfer into the gas ph…

Applications of YBa2Cu3Ox(YBCO) coated conductors require strong vortex pinning to ensure a non-dissipative state over a large range of temperatures and magnetic field values. Incorporations of nanoparticles and nanorods have generally resulted in a substantial increase of pinning, but the actual mechanism producing t…

Abstract We present results on the use of multilayered a‐SiC:H heterostructures as an integrated device for simultaneous measurement and wavelength‐division demultiplexing of optical signals. These devices are useful in optical communications applications that use the wavelength division multiplexing technique to enco…
Background: Although cardiac fibrosis is associated with increased incidence of cardiac arrhythmias, the underlying proarrhythmic mechanisms remain incompletely understood and antiarrhythmic therapies are still suboptimal. Objective: To test the hypothesis that myofibroblasts (MFB) proliferation leads to tachyarrhythm…
