Subpicosecond time-resolved absorption measurements at 77 K on two reaction center (RC) mutants of Rhodobacter capsulatus are reported. In the D(LL) mutant the D helix of the M subunit has been substi...
The rates of electron-transfer reactions can be systematically varied by application of external electric fields. The electric field effect on the charge recombination rate constant of the state P[sup...
The time-dependent wavepacket diffusion method for carrier quantum dynamics (Zhong and Zhao 2013J. Chem. Phys.138014111), a truncated version of the stochastic Schrödinger equation/wavefunction a...
The hierarchical equations of motion technique has found widespread success as a tool to generate the numerically exact dynamics of non-Markovian open quantum systems. However, its application to low ...
An exact method to compute the entire equilibrium-reduced density matrix for systems characterized by a system-bath Hamiltonian is presented. The approach is based upon a stochastic unraveling of the ...
In our recent work [Phys. Chem. Chem. Phys. 11, 9149 (2009)], a molecular-mechanics force field-based amide-I vibration frequency map (MM-map) for peptides and proteins was constructed. In this work, ...
Understanding the mechanisms of efficient and robust energy transfer in light-harvesting systems provides new insights for the optimal design of artificial systems. In this paper, we use the Fenna-Mat...
Novel packed-capillary columns for gas chromatography were developed with a thin-wall stainless-steel capillary of 1.0 mm i.d.; and rapid temperature-programmed separations have been carried out after...
A novel method for the evaluating the transpiration rate (TR) has been proposed. Miniature temperature/humidity loggers were attached onto the leaf surface of a mangrove plant, Bruguiera gymnorrhiza, ...
Using ultraviolet (UV)-excited ozone gas, we prepared high-quality SiO2 films that can be used as gate dielectric films on poly-silicon or silicon wafers without sample heating. The UV-excited ozone g...
利用可见-近红外光谱技术结合最小二乘支持向量机(LS-SVM)对不同贮存温度下的蜂花粉进行鉴别。选择-20、4、15、25和40℃ 5个温度下分别贮存60d后的蜂花粉为研究对象。对原始光谱数据进行平滑和附加散射校正(MSC)的预处理后进行主成分分析,选择4~20个主成分作为输入变量进行LS-SVM建模。模型预测参数比较结果显示,当主成分数取20时模型的预测效果最好,预测相关系数r2p≥0.9919...
Arylperimidines, 3(a-l), were synthesized in good yields by cyclocondensation reaction of 1,8-diaminonaphthalene and aromatic aldehydes in the presence of NaY zeolite as a catalyst. The simple environ...
摘要 Quinoxaline derivatives have been synthesized in a very short time with excellent yields by the condensation of 1,2-diamines with aliphatic or aromatic 1,2-dicarbonyl compounds or benzilmonoxime in...
The kinetics of low temperature CO oxidation were studied over sequentially impregnated 1wt%Pt-0.25wt%SnOx supported on HNO3-oxidized activated carbon (AC3) using a wide range of CO (1-10 mol%) and O2...
The cold-melting mechanism and the cold-dissolving-melting mechanism were further studied by TG/DSC and in situ micro-photographs techniques with the mixture of hexamethylene tetramine and CoCl2·6H2O ...
