Dry reforming of methane (DRM) has provided an effective avenue to convert two greenhouse gases, CH4 and CO2 , into syngas. Here, we design a DRM photocatalyst Rh/Cex WO3 that invokes both photothermal photoelectric processes, which overcomes the thermodynamic limitation under conventional conditions. In contrast plasmonic or UV-response photocatalysts, our produces superior light-to-chemical energy efficiency (LTCEE) 4.65 % with moderate light intensity. We propose light-induced...
Sleep is known to benefit consolidation of memories, especially those motivational relevance. Yet, it remains largely unknown the extent which sleep influences reward-associated behavior, in particular, whether and how modulates reward evaluation that critically underlies value-based decisions. Here, we show neural processing during can selectively bias preferences simple economic choices when sleeper stimulated by covert, cues. Specifically, presenting spoken name a familiar, valued snack...
Listener vmPFC simulates speaker utterance choices in a rational, automatic way to recover unstated intent communication.
Consistent descriptions of the equation states, and information about transport coefficients deuterium-tritium mixture are demonstrated through quantum molecular dynamic (QMD) simulations (up to a density 600 g/cm$^{3}$ temperature $10^{4}$ eV). Diffusion viscosity compared with one component plasma model in different regimes from strong coupled kinetic one. Electronic radiative coefficients, which models currently used hydrodynamic inertial confinement fusion, evaluated up 800 eV. The...
In recent years, single image dehazing methods based on Atmospheric Scattering Model (ASM) have achieved state-of-the-art results. But the outputs of those suffer from color shift and blocking effect. Our preliminary experiments show that negative bias estimated transmission tiny value will cause serious shift. Therefore, in this study, a new loss function (TransLoss) natural activation (NAF) are proposed to restrain avoid being activated, respectively. Moreover, it is noted block effect...
We have performed first-principles molecular-dynamics simulations based on density-functional theory to study the thermophysical properties of ethane under extreme conditions. present results for equation state fluid in warm dense region. The optical conductivity is calculated via Kubo-Greenwood formula from which dc and reflectivity are derived. close correlation between nonmetal-metal transition its decomposition, that dissociates significantly into molecular and/or atomic hydrogen some...
In the frequency dissemination system over fiber, users can obtain highly stable RF signal from one source. To ensure that stability loss of meets user's need, performance evaluation for fiber is necessary. Considering numerous links and long distance, traditional transfer quality method not very practical, because cost loop-back configuration relatively large. this paper, we propose a to directly evaluate radio via at remote site. At local site, amplitude-modulated on continuous-wave lasers...
Isolated DC/DC converters have the disadvantage of inefficiency, instability, magnetic bias and shoot-through problems, etc.They also influence other electrical devices severely in same power network.Therefore, a novel photovoltaic off-grid inverter based on boost converter is designed this paper.The following works been done study: to design circuit inverter, parameters simulate.The research paper has laid theoretical foundation for industrial applications.
Abstract The network of smart cities is a typical complex with big data in the theoretical level and practical level. How can we analysis better under complexity uncertainty. It question. We try to give new framework this question, providing chance make city smarter.
Rapid laser heating is an important experimental technique to achieve extreme conditions for uranium. Theoretical simulations of the electron–ion nonequilibrium energy relaxation after usually employ a two-temperature model using thermal quantities electron heat capacity and electron–phonon coupling factor as input parameters. Based on first-principles calculations density states Eliashberg function, we theoretically determine their dependence temperature external pressure uranium revealed...
Alcoholysis and hydrolysis of NaBH4 to produce H2 offer attractive routes sustainable development with high energy density environmentally-friendly features. However, the productivity is often limited by increased alkalinity reaction system deactivation catalysts. Here, we present a novel strategy constructing polyol/water composite promote catalyst free alcoholysis while inhibiting ionization products. The exhibits conversion more than 90% in less 60 min, especially when erythritol/water...
An accurate equation of state for deuterium-tritium mixture is crucial importance in inertial confinement fusion. The can determine the compressibility imploding target and energy deposited into fusion fuel. In present work, a new state, which calculated according to quantum molecular dynamic orbital free simulations, has been used study implosion hydrodynamics. results indicate that peak density predicted by ∼10% higher than quotidian data. During implosion, areal neutron yield are also discussed.
