Abstract Hypothesis Combination of microwave irradiation (MWI) and ionic liquids (IL) is widely used for the synthesis of nanoparticles (NP) via decarbonylation of zero-valent metal carbonyl precursors. However, we carefully raise a question as to whether this combination is always beneficial. Upon MWI, highly-absorbing materials such as ILs would be subject to local intense heating, likely resulting in the occurrence of localized chemical decomposition. The decomposition is expected to influenc...

Carbon fiber reinforced plastics (CFRPs) have high specific stiffness and strength, but they are vulnerable to transverse loading, especially low-velocity impact loadings. The impact damage may cause serious strength reduction in CFRP structure, but the damage in a CFRP is mainly internal and microscopic, that it is barely visible. Therefore, this study proposes a method of determining impact damage in CFRP via poly(vinylidene fluoride) (PVDF) sensor, which is convenient and has high mechanical ...

For a robotic grasping task in which diverse unseen target objects exist in a cluttered environment, some deep learning-based methods have achieved state-of-the-art results using visual input directly. In contrast, actor-critic deep reinforcement learning (RL) methods typically perform very poorly when grasping diverse objects, especially when learning from raw images and sparse rewards. To make these RL techniques feasible for vision-based grasping tasks, we employ state representation learning...

Abstracts Cu-poor CIGS thin films were fabricated by RF magnetron sputtering from a single quaternary target with the composition of Cu0.7In0.7Ga0.3Se2, in an effort to improve the cell efficiency of CIGS solar cells. The Cu-poor thin films with the ([Cu]/[In]+[Ga]) composition ratios of 0.70–0.77 were obtained showing that the composition of the target can be transferred to the film. It was also observed that the strongly (220)/(204) preferred orientation appeared at the substrate temperatures ...

Abstract In this paper, particles produced by a high velocity impact were first analyzed numerically by using smooth particle hydrodynamics (SPH). Then, a method to cluster the particles into fragments dispersed in a space due to the impact was developed. High velocity impact simulations using SPH on different types of projectiles and target plates were conducted, and the predicted results including the residual velocity, hole diameter, and spall ring diameter in the target plate were verified b...
