Expediting the torpid kinetics of oxygen reduction reaction (ORR) at cathode with minimal amounts Pt under acidic conditions plays a significant role in development proton exchange membrane fuel cells (PEMFCs). Herein, novel Pt–N–C system consisting single atoms and nanoparticles anchored onto defective carbon nanofibers is proposed as highly active ORR catalyst (denoted Pt–N–C). Detailed characterizations together theoretical simulations illustrate that strong coupling effect between...
Hierarchical equations of motion theory for Drude dissipation is optimized, with a convenient convergence criterion proposed in advance numerical propagations. The theoretical construction on the basis Padé spectrum decomposition that has been qualified to be best sum-over-poles scheme quantum distribution function. resulting hierarchical dynamics under priori are exemplified benchmark spin-boson system, and also transient absorption related coherent two-dimensional spectroscopy model...
We present an optimized hierarchical equations of motion theory for quantum dissipation in multiple Brownian oscillators bath environment, followed by a mechanistic study on model donor-bridge-acceptor system. show that the optimal hierarchy construction, via memory-frequency decomposition any specified bath, is generally achievable through universal pre-screening search. The algorithm goes identifying candidates best be just some selected Padé spectrum based schemes, together with priori...
Herein, three novel electron donor-acceptor rings ( DARs ) were synthesized, in which four methoxy groups introduced DARc to study the influence from substituents on their properties. Their photoluminescence was...
Using dehydrobenzoannulene as an acceptor, two curved π-conjugated electron donor–acceptor architectures were concisely synthesized, and unexpected deshielding effect was observed in the annulene fragment. Anomalously, π-extended homologue exhibited blue-shifted fluorescence. Intriguingly, stunning stable electrochemiluminescence emissions first discovered nonaromatic derivatives. Finally, based on those properties, a highly efficient sensor for detecting dopamine constructed. This work...
Utilizing [14]dehydrobenzoannulene as an electron acceptor, four twisted donor-acceptor architectures were divergently synthesized. Intriguingly, the antiaromatic diazocine core could interrupt transfer in π-frameworks. Benefiting from junction of dehydrobenzoannulene and carbazoles, all displayed stunning fluorescence electrochemiluminescence. Anomalously, blue-shifted was observed electron-donating-group-substituted homologues. Finally, a molecular carbon-based sensor for dopamine...
CeVO<sub>4</sub> hierarchical hollow microspheres assembled from nanoscaled building units (nanoparticles, nanocubes and nanoflakes) were synthesized by a one-step hydrothermal approach using <sc>l</sc>-Asp as the morphology-directing agent.
A nonperturbative quantum dissipation theory is developed based on an optimal construction of biexponential Drude bath correlation function for its influence the system dynamics. It advanced hierarchical master equation approach, aiming at a numerically efficient non-Markovian propagator, with support convenient criterion to estimate in advance accuracy general systems. Compared low level, single-exponential counterpart [R. X. Xu et al., J. Chem. Phys. 131, 214111 (2009)], present remarkably...
A unified theory for minimum exponential-term ansatzes on bath correlation functions is proposed numerically efficient and physically insightful treatments of non-Markovian environment influence quantum systems. For a general Brownian oscillator frequency Ω friction ζ, the ansatz results in function bi-exponential form, with effective Ω¯ ζ¯ being temperature dependent satisfying Ω¯/Ω=(ζ¯/ζ)1/2=r¯BO/rBO≤ 1, where r¯BO=ζ¯/(2Ω¯) rBO=ζ/(2Ω). The maximum value r¯BO=rBO can effectively be reached...
We revisit Caldeira-Leggett's quantum master equation representing mixed quantum-classical theory, but with limited applications. Proposed is a Fokker-Planck generic bi-exponential correlation function description on semiclassical Brownian oscillators' environments. The new theory has caustic terms that bridge between the primary systems and or quasi-classical Various parametrization schemes, both analytical numerical, for environment bath functions are proposed scrutinized. of same...
A new glucosyl triblock PGNA copolymer was first synthesized and the aqueous solution exhibits good sol–gel phase transition behaviours. The formed hydrogels are sensitive to temperature pH.
We compare the results of some perturbative quantum dissipation approaches to exact linear absorption two state systems. The considered approximate methods are so-called complete second-order theories, in either chronological ordering prescription or correlated driving-dissipation form. Analytical can be derived for two-state Assessments on their applicability then made by comparison results.
