TL;DR: In this article, a suite of transmission electron microscopy (TEM) and associated electron spectroscopy methods were used to examine the local structure and changes in the electronic structure of LiNi 0.8 Co 0.15 Al 0.05 O 2 positive electrode material.
Abstract: We used a suite of transmission electron microscopy (TEM) and associated electron spectroscopy methods to examine the local structure and changes in the electronic structure of LiNi 0.8 Co 0.15 Al 0.05 O 2 positive electrode material. We found a scattered rock-salt phase near grain surfaces and grain boundaries, where Ni 3+ turned to Ni 2+ , deduced from relative intensity ratios and fine structures of the L 2,3 white-line peaks of the transition metals. The spatial distribution of the degraded phase throughout the secondary particle was found using a scanning TEM-electron energy loss spectroscopy spectral imaging technique and multivariate analysis. The degradation process and its relationship to the surface reactions with electrolytes is discussed based on the spatial-distribution map of the degraded phases.

TL;DR: In this paper, an indicator display that can be visually recognized by a driver is disposed in a compartment of the vehicle, and a front camera for filming an area stretching forwards is placed in a front portion of a vehicle.
Abstract: A front camera for filming an area stretching forwards is disposed in a front portion of a vehicle. A side camera for filming an area stretching laterally and diagonally forwards is disposed in a lateral-left portion of the vehicle. An indicator display that can be visually recognized by a driver is disposed in a compartment of the vehicle. An amount of change in the direction of the vehicle, that is, a deflection angle of the vehicle is detected on the basis of a vehicle speed and a steering angle of a steering wheel, which have been detected by means of various sensors. After the indicator display has started displaying a lateral photo image filmed by the side camera, the photo image displayed by the indicator display is shifted from the lateral photo image filmed by the side camera to a front photo image filmed by the front camera if the deflection angle has reached a predetermined angle.

TL;DR: In this paper, a morphotropic phase boundary (MPB) between orthorhombic and tetragonal has been developed, which exhibits a piezoelectric actuator constant d 33 of 230 pm/V, 2.34 times that of pure (K 0.5 Na0.5 )NbO 3 (KNN).
Abstract: A new solid solution system, namely {(K 0.5 Na 0.5 ) 1− x Li x }(Nb 1− y Ta y )O 3 , with full density, a large piezoelectric constant and high stability has been developed. The system has a morphotropic phase boundary (MPB) between orthorhombic and tetragonal. The MPB gives the largest piezoelectric d constant at {(K 0.5 Na 0.5 ) 0.97 Li 0.03 }(Nb 0.8 Ta 0.2 )O 3 , which exhibits a piezoelectric actuator constant d 33 of 230 pm/V, 2.34 times that of pure (K 0.5 Na 0.5 )NbO 3 (KNN). Also, it gives a piezoelectric coupling Kp value (0.505), a dielectric constant (1256), and an elastic compliance (10.9 TPa−1 ) 1.51, 2.93, and 1.14 times those of pure KNN, respectively. The long-term stability of the dielectric loss was demonstrated to be far superior to that of pure KNN.

TL;DR: Major recent advances in nonaqueous Mg electrochemistry are highlighted, notably the development of electrolytes and cathodes, and some of the challenges that must be overcome to realize a practical magnesium battery are discussed.
Abstract: Magnesium is an ideal metal anode that has nearly double the volumetric capacity of lithium metal with a very negative reduction potential of −2.37 vs SHE. A significant advantage of magnesium is the apparent lack of dendrite formation during charging, which overcomes major safety and performance challenges encountered with using lithium metal anodes. Here, we highlight major recent advances in nonaqueous Mg electrochemistry, notably the development of electrolytes and cathodes, and discuss some of the challenges that must be overcome to realize a practical magnesium battery.
