Despite tellurium being less abundant in the Earth's crust than gold, platinum, or rare‐earth elements, the number of industrial applications of tellurium has rapidly increased in recent years. However, to date, many properties of tellurium and its associated compounds remain unknown. For example, formation mechanisms of many tellurium nanostructures synthesized so far have not yet been verified, and it is unclear why tellurium can readily transform to other compounds like silver telluride by simply mixing with solutions containing silver ions. This uncertainty appears to be due to previous misunderstandings about the tellurium structure. Here, a new approach to the tellurium structure via synthesized structures is proposed. It is found that the proposed approach applies not only to these structures but to all other tellurium nanostructures. Moreover, some unique tellurium nanostructures whose formation mechanism are, until now, unconfirmed can be explained. 相似文献

While driving research on affect has mostly focused on anger and road rage, there has been little empirical research on other affective states. Affect researchers widely acknowledge the “sadder but wiser” phenomenon, but there is little evidence if this tendency can be applied to the driving environment as well. The objective of the present study is to empirically test whether sadness enhances driving performance as the sadder but wiser notion might predict or sadness impairs driving performance as its negative valence or low arousal dimension might predict. The study consists of a simulated driving experiment with induced anger, sadness, and neutral affect to examine how anger and sadness influence driving-related risk perception, driving performance, and perceived workload. Sixty-one young drivers drove under three different road conditions with either induced anger, sadness, or neutral affect conditions. After affect induction, there was no difference in subjective risk perception across three affect conditions. However, participants in both affect conditions showed significantly more errors and took longer driving time than those in the neutral condition. Only participants with induced anger reported significantly higher physical workload and frustration than participants with neutral affect. Results are discussed in terms of affect mechanisms, design directions for the in-vehicle affect mitigation system, and limitations of the study. 相似文献

We investigated the electronic perturbation between graphene oxide and cobalt porphyrin to reveal the origin of the enhanced electrocatalytic activity of a hybrid complex using time-resolved spectroscopic measurements and theoretical calculations. The impulsively generated charge-separated state, GO−-(CoIIAPFP)+, undergoes fast charge recombination (<10 ps) between GO− and (CoIIAPFP)+ moieties. This fast charge recombination is directly related to the quick neutralization of (CoIIAPFP)+, which shortens the dead time of inactive CoIIIAPFP after the electrocatalytic reduction reaction. The fast transformation of inactive CoIIIAPFP to active CoIIAPFP is an important factor in the enhanced electrocatalytic activity of the hybrid complex. 相似文献

Effect of sodium dodecyl sulfate (SDS) on the adsorption of Zn(II) and Ni(II) on CMOC was investigated. Addition of SDS favored the adsorption process. Adsorption process was found to be dependent on concentration, pH, dose, contact time and temperature. Thermodynamic studies showed that the process is endothermic and spontaneous. The spontaneity increases with increase in temperature. D–R isotherm suggests that the adsorption is chemical in nature. Kinetics studies showed better applicability of pseudo second order model. Reichenberg equation showed that pore diffusion was not only the rate determining step but some other process like film diffusion was also involved in the adsorption. These metals could be desorbed (75–80%) with 0.1 M HCl as eluent. 相似文献

A femoral artery pseudoaneurysm is one complication of vascular intervention, and the incidence is increasing. Early management is then needed to avoid potential dangers from it. It differs from a true aneurysm in that it doesn't include any component of the vascular wall, and is not studied as much as a true aneurysm. Here, a model of a femoral pseudoaneurysm was made and a Computational Fluid Dynamics(CFD) simulation was verified with PIV experiment. Afterwards, a CFD simulation with two different models was performed to look for any findings which may help in developing new treatment methods. 相似文献
