PURPOSE: The purpose of this work is to study the influence of photon energy cuts on the results of positron emission tomography (PET) Monte Carlo (MC) simulations. METHODS: MC simulations of PET scans of a box phantom and the NEMA image quality phantom are performed for 32 photon energy cut values in the interval 0.3…
A new 2-D coordination polymer, Co(H2O)2(Hoba)2 (1) [H2oba = 4,4′-oxybis(benzoic acid)], was synthesized under hydrothermal conditions. Polymer 1 has been characterized by single-crystal X-ray diffraction and TG analysis. Through hydrogen bonds 1 shows a supramolecular four-connecting 3-D matrix with 4284 PtS topology…

We present measurements of the temperature dependence of the electrical resistivity ρ(T) of CeRhSn up to ~27 kbar. At low temperatures, ρ(T) varies linearly with T for all pressures, indicating non-Fermi liquid behavior. Below Tf ~ 6 K, ρ(T) deviates from a linear dependence. We found that the low-T feature centered a…
Availability of Defect-free blank is one of the most critical issues for high volume mask production in EUV lithography. Blank defects will disrupt the structure of multi-layers and will cause phase defects in EUV lithography. Phase defects caused by the disruption in the structure of multi-layers are difficult to rep…
We report the facile and economical synthesis of an electrochromic copolymer for black based on electrochemical copolymerization of thiophene and 3, 4-ethylenedioxythiophene in boron trifluoride diethyl etherate. The resultant copolymer presents multicolor electrochromism with reversible color change between drab colo…
采用氟气（F2）对聚（对亚苯基-1，3，4-噁二唑）（p-POD）纤维表面进行直接氟化处理．衰减全反射红外光谱（ATR-FTIR）和表面电子能谱（XPS）的结果显示，通过直接氟化处理，p-POD纤维较易与F，发生反应，表面大分子链上引入了大量C-F键，表面氟元素含量高达28．2％，且F原子以-CF／C-O、-CFH及-CF2形式存在，表明在表面氟化过程中，既有取代反应，也有加成反应．热失重（TGA）结果表明氟化前后P-POD纤维的耐高温性能没有受到影响，X射线衍射图谱（XRD）表明氟化后纤维的聚集态有序性略微增加．氟化前后纤维的断裂强度基本无变化，在体积分数为20％的硫酸溶液中的人工加速酸老化条件下，氟化后纤维在老化120h后的断…

Cutaneous leishmaniasis (CL) which is caused by the different species of Leishmaina, produces a skin ulcer that heals spontaneously in most cases, leaving an unsightly scar. In the traditional medicine, the extracts of different species of Calotropis gigantea have been successfully used for the treatment of cutaneous…
This paper is concerned with the steady states of a one-dimensional strongly nonlinear PDE system arising from the study of phase transitions with microscopic movements. Using the plane analysis method, we prove that the number of equilibria is at most infinitely countable. Furthermore, we show that the global solutio…
Since the layout patterns on photomasks have been getting more and more complicated by OPC/RET processes, the mask patterns need to go through the verification to check the mask manufacturability even though the layout is 'DRC clean'. This verification process is called MRC (mask rule check). The fundamental functions…
This study deals with a biorefinery concept based on larch wood. Wood chips of Siberian larch (Larix sibirica Lebed.) were treated with water before pulping at the optimal pre-extraction (PE) condition of 150 °C and 90 minutes. Through PE, about 12.4% of the wood mass is dissolved, mainly from the arabinogalactan hemi…

A superconductor is a remarkable emergent state of matter in which electrons pair up and develop long range phase coherence resulting in zero resistance and perfect diamagnetism. How can a superconductor decohere? A thin superconducting film can be driven insulating in a remarkable number of ways: decreasing thickness…
ABSTRACT The impact of laterally non‐uniform carrier lifetime on the determination of the lifetime from photoconductance‐based measurements, based on the self‐consistent method proposed by Trupke and Bardos, is investigated using a simple model. It is shown that the method can result in an overestimation of the mean l…
Y2O3:(Eu3+,Gd3+) is introduced into a dye-sensitized solar cell. As a luminescence medium, Y2O3:(Eu3+,Gd3+) improves light harvest via conversion luminescence process and increases photocurrent; as a p-type dopant, Y2O3:(Eu3+,Gd3+) elevates photovoltage. The cell's light-to-electric energy conversion efficiency enhanc…
通过冷冻-熔融法制备了细菌纤维素/聚乙烯醇/聚乙烯吡咯烷酮(BC/PVA/PVP)双网络复合水凝胶,并采用X射线衍射,红外光谱,扫描电镜,力学性能测试等手段对凝胶的结构和性能进行表征.研究发现PVA、PVP通过氢键作用均匀地吸附于纤维微丝周围,将BC纤维有效地分开,因而干燥后的复合凝胶在热水中浸泡后仍可恢复原状;X射线衍射结果显示,直接干燥成膜样品和冻干样品的结晶性能差别明显,且PVA/PVP对BC的结晶有抑制作用,而BC增强复合凝胶中PVP对PVA结晶的影响作用与纯PVA/PVP体系类似,即少量PVP的存在对PVA的结晶有促进作用,浓度超过2%的PVP反而对PVA的结晶有抑制作用;力学性能测试结果表明,细菌纤维素的引入,明显地提…
This work presents a relativistic calculation of electron delocalization, optical properties, and zero field splitting in a group of molecules with the structure (C(8)H(8))M(μ(2)-,η(8)═C(8)H(8))M(C(8)H(8)), where M = Ti, Zr and Th. Additionally we also studied the heterobimetallic combinations (Ti-Th and Zr-Th). The m…
Abstract A monomer of the AB‐type and a bifunctional comonomer of the AA‐type containing two 2‐oxazoline rings and a biphenyl structural unit were prepared from the corresponding carboxylic acids via their esterification and subsequent amidation with an aminoalcohol. The cyclization of an amide to 2‐oxazoline structur…
