Summary: Lithium-ion batteries are the leading energy storage technology due to their high energy density. The electrode architecture and microstructure can be engineered to further enhance the energy density, in addition to traditional improvements through materials chemistry. Active material (AAM) electrodes, which only consist of the electroactive material, have advantages over conventional composite electrodes in terms of mechanical stability and ion transport properties. However, the absence of binders and composite processing makes AAM electrodes more susceptible to volume changes in the electroactive material during cycling. The use of TiNb2O7 (TNO) and MoO2 (MO) as multicomponent AAM anodes shows promising results in terms of energy density, rate capability, and cycle life.

Summary: This study presented experimental results on intermittent cutting of quenched steel AISI 52100 using a PcBN tool. The finite element method was used to analyze the machining process, considering the polycrystalline structure and composition of the tool. Experimental results showed that a PcBN tool with low PcBN content had comparable efficiency to a tool with high PcBN content when machining quenched steel AISI 52100 at a cutting speed of 210 m/min under intermittent cutting conditions. These findings demonstrate the potential and high performance of tools made from PcBN composites with different compositions under specific operational conditions.

Summary: Inhomogeneous swelling of fluoroelastomer films in liquid environments can be used in soft actuators and sensors. We report an abnormal size-dependent bending phenomenon of rectangular fluoroelastomer films, where the bending direction changes from long-side bending to short-side bending with increasing length or width or decreasing thickness. By using finite element analysis and a bilayer model, we reveal the key role of gravity in determining the size-dependent bending behavior. These findings can be useful for designing swelling-based polymer actuators and sensors in the future.
