Herein, we report the function of copper sites in Cu-SSZ-13, Cu-ZSM-5 and Cu-Beta catalysts with the same Si/Al ratio (14) and Cu/Al ratio (0.4) on selective catalytic reduction of NO with NH3 (NH3-SCR) and reveal the relationship between active sites (Cu sites, acid sites) and catalytic activity. The results show that the amount of isolated Cu2+ ions in the catalysts directly determines the formation of strong Lewis acid sites and reaction intermediate NO3− ions, thus affecting the low-temperature SCR performance, while the amount of highly stable Cu+ ions and Brønsted acid si

Based on metal-oxide-semiconductor field-effect transistor (MOSFET) devices and Von Neumann architecture semiconductor chip technology has led mankind into the information age. In recent years, new computing architectures have flourished. However, specialized algorithms and When mapping brain-like intelligent algorithms to MOSFET circuits, they usually face challenges such as high hardware overhead and low system energy efficiency. In response to the above problems, this paper developed a New transistor devices with the characteristics of fusion of storage and calculation are effectively ad

The cone photoreceptors in our eyes selectively transduce the natural light into spiking representations, which endows the brain with high energy-efficiency color vision. However, the cone-like device with color-selectivity and spike-encoding capability remains challenging. Here, we propose a metal oxide-based vertically integrated spiking cone photoreceptor array, which can directly transduce persistent lights into spike trains at a certain rate according to the input wavelengths. Such spiking cone photoreceptors have an ultralow power consumption of less than 400 picowatts per spike in vi

Black Carbon (BC), the second-largest contributor to global warming, has detrimental effects on human health and the environment. However, the accurate quantification of BC poses a significant challenge, impeding the comprehensive assessment of its impacts. Therefore, this paper aims to critically review three quantitative methods for measuring BC: Thermal Optical Analysis (TOA), the Optical Method, and Laser-Induced Incandescence (LII). The determination principles, available commercial instruments, sources of deviation, and correction approaches associated with these techniques are system

Because of the high cost and scarcity of Pt, the commercialization of fuel cell technology is still facing a great challenge. Compared with the proton exchange membrane fuel cell, one advantage of the anion exchange membrane fuel cell (AEMFC) is the possibility of partially replacing or completely removing Pt catalyst in the cathode. Recently, the oxygen reduction reaction (ORR) of transition metals (such as Fe, Co, Ni as well as their compounds) in alkaline environments has been greatly improved, with substantial efforts devoted to controlling the nanostructure and adjusting the active sit
