A MOF-derived composite with multi-functional effects for high-performance Li–S batteries, especially its Co–N dual-catalyzing S redox.
High-index surfaces of a face-centered cubic metal (e.g., Pd, Pt) have high density low-coordinated surface atoms and therefore possess enhanced catalysis activity in comparison with low-index faces. However, because their energy, the challenge chemically preparing nanocrystals having high-index facets remains. We demonstrate this work that introducing amines as controller allows concave Pt {411} to be prepared through facile wet-chemical route. The as-prepared display unique octapod...
Because of the high theoretical capacity 1675 mAh g–1 and energy density 2600 Wh kg–1, respectively, lithium–sulfur batteries are attracting intense interest. However, it remains an enormous challenge to realize utilizations loadings sulfur in cathodes for practical applications Li–S batteries. Herein, we design a quasi-2D Co@N–C composite with honeycomb architecture as multifunctional host via simple sacrificial templates method. The cellular flake large surface area can encapsulate much...

A unique SEI is established, which can be rooted in metal via situ pre-implantation of atoms, called a (R-SEI).
Constructing powerful anode/cathode interphases by modulate ion solvation structure is the principle of electrolyte design. However, methodological and theoretical design principles electrolyte/solvation their effect on electrochemical performance are still vague. Here, we propose a cationic weakly coordinating-intervention strategy for modulating Na+ sheathes constructing robust in sodium-metal batteries. Unlike local highly concentrated electrolytes, 1,2-difluorobenzene can coordinate with...
Today's computing systems, to meet the enormous demands of information processing, have driven development brain-inspired neuromorphic systems. However, there are relatively few optoelectronic devices in most systems that can simultaneously regulate conductivity through both optical and electrical signals. In this work, Au/MXene/Y:HfO2/FTO ferroelectric memristor as an artificial synaptic device exhibited digital analog resistance switching (RS) behaviors under different voltages with a good...

Crystal phase engineering is an important strategy for designing noble-metal-based catalysts with optimized activity and stability. From the thermodynamic point of view, it remains a great challenge to synthesize unconventional phases noble metals. Here, new class Pd-based nanostructure rhombohedral Pd20 Sb7 successfully synthesized.

Antibiotics play an essential role in the treatment of various diseases. However, overuse antibiotics has led to pollution water bodies and food safety, affecting human health. Herein, we report a dual-emission MOF-based flexible sensor for detection water, which was prepared by first encapsulating rhodamine B (RhB) zeolite imidazolium ester skeleton (ZIF-8) then blending it with polyvinylidene difluoride (PVDF). The luminescent properties, structural tunability, porosity composites were...
Abstract For the lithium (Li) metal anode, constructing a strong and durable protective layer with lithium‐ion permeability is crucial, especially in high donor number (DN) solvent system. High DN solvent‐based electrolytes can support both higher capacity lower charge overpotential rechargeable lithium–oxygen batteries (LOBs). However, Li anodes system suffer from severe corrosion uncontrolled dendrite growth due to unstable solid‐electrolyte interphase (SEI). Typically, this interface...

Dissolved gas analysis (DGA) is a popular method for diagnosing faults inside power transformers. However, some of the recorded data are with ambiguous characteristic, leading to misdiagnosis conventional methods. In this work, hybrid method, which combines relevance vector machine (RVM) and adaptive neural fuzzy inference system (ANFIS) has been proposed address issue. Given fuzziness between DGA records fault type, minimise number rules that ANFIS needs extract, RVM algorithm performs...
Solid-state lithium metal batteries are hindered from practical applications by insufficient room-temperature ionic conductivity and poor electrode/electrolyte interfaces. Herein, we designed synthesized a high metal–organic-framework-based composite solid electrolyte (MCSE) with the synergy of DN value ligands Uio66-NH2 succinonitrile (SN).
