Abstract The performance of Li batteries is influenced by the + solvation structure, which can be precisely adjusted components electrolytes. In this review, we overview strategies for optimizing electrolyte structures from three different perspectives, including anion regulation, binding energy and additive regulation. These optimize composition electrode‐electrolyte interface, enhance anti‐oxidative stability electrolytes as well regulate behaviors anions, solvents, during cycling process....
Due to the advantages of their structure and component, as-synthesized electrospun MoO<sub>3</sub>@C nanofibers could maintain a high reversible capacity 623 502 mA h g<sup>−1</sup> after 100 cycles at 500 1000 g<sup>−1</sup>, respectively.
A delicate method is developed to embed WS<sub>2</sub> nanosheets into lotus rhizome-like heteroatom-doped carbon nanofibers with abundant hierarchical tubes inside. The exhibit enhanced performance in sodium-ion batteries.
Semi-airborne electromagnetic method (SAEM) is a geophysical detection which places the transmitting subsystem on ground and receiver flight platform. This transceiver configuration has been found to be more efficient than that of traditional methods while it can get much deeper penetration airborne methods. Therefore, SAEM widely used in mineral, groundwater, geothermal, other resources exploration fields. In this paper, we would like take most key problems encountered system design...
The traditional source uses a square wave with fixed fundamental frequency to excite transient electromagnetic (TEM) fields, harmonic energy primarily concentrated in the low-frequency range, limiting detection resolution of TEM. differential pulse, composed two waves identical pulse widths but opposite polarities, concentrates more effectively. By adjusting width concentration band can be changed, enabling multi-resolution geological structures at different depths. In this study, TEM fields...

Abstract The development of efficient electrochemical energy storage devices is crucial for future renewable management. Aqueous rechargeable batteries (ARBs) are considered to be one the most sustainable battery technologies due their low cost, ease manufacture, high safety and environmental friendliness. However, some tough issues, such as narrow stability window water, chemical instability electrode materials, uncontrollable dendrite growth poor cycling lifespan, severely limit...

However, it requires solving dozens large sparse...
The efficacy of full lightweight ceramsite concrete as a restorative material has been widely acknowledged, given its light weight, strength, and durability. However, the extent performance in repairing existing or old remains uncertain. This study examined reparation flexural with concrete, using 14 different combinations new test blocks. primary focus was on investigating bond strength interface between concrete. included understanding effects interfacial roughness, agent type, curing age...

Multi-grounded source transient electromagnetic methods advantages large detection depths easy deployment emission sources. Therefore, they can be used for explorations such complex areas as mountains, lakes swamps. Previously, grounded had only one arranged on surface, were relatively rarely...
Unexploded ordnance (UXO), which causes many civilian casualties every year, has become a serious environmental problem. To deal with the problem, we have developed new drone-based transient electromagnetic (TEM) system, was designed for UXO detection through very low altitude measurements. Drone-based TEM system uses rotorcraft equipped central loop device to realize detection. The more safe and efficient than ground-based in Compared airborne magnetic method or helicopter-borne it...
The topography has serious effects on time-domain airborne electromagnetic (AEM) signal, and the EM responses resulted from frequently overwhelm those underground abnormal bodies.
