Polymer zwitterions are more promising cathode interlayers (CILs) for fused-ring electron acceptor (FREA)-based organic solar cells (OSCs) than amine-containing CILs and polyelectrolytes. However, they usually suffer from high synthetic cost low mobilities. Herein, we present a novel strategy that combines the n-type doping effect with polymer to develop new nonconjugated self-doped zwitterion (s-PZ), namely, PDI-M-DAN. PDI-M-DAN is afforded via cost-effective transition-metal-free...

In this paper, photonic reservoir computing chip architectures for noise equalization in optical fiber communication channels are proposed. These leverage instead of electrical to reduce computational pressure at the receiver and decrease processing latency. We examine impact factors such as number nodes, waveguide delay line length, input/output ports on performance. discuss ability these under various types noise. After parameter optimization, 36-node layout achieves a...

An unprecedented copper and in situ-generated triflic acid relay-promoted four-component cascade reaction of cyanamides, diaryliodonium triflates, propargylic amines, H2O was established for rapid concise construction diverse five-membered cycloguanidines. Copper-catalyzed guanidination/intramolecular hydroamination HOTf-accelerated hydration proceeded sequentially with high level chemoselectivity regioselectivity, six new bonds were simultaneously built yields. Thus, triflates served not...

Purpose Gas-insulated switchgear (GIS) stands as a pivotal component in power systems, susceptible to partial discharge occurrences. Nevertheless, manual inspection proves labor-intensive, exhibits low defect detection rate. Conventional robots face limitations, unable perform live line measurements or adapt effectively diverse environmental conditions. This paper aims introduce novel solution: the GIS ultrasonic robot (GBOT), designed assume role of substation personnel tasks....

Indoor positioning is the key technology for intelligent mobile platform, and laser SLAM a typical high accuracy solution. Compared with 2D method, 3D higher computational complexity. To improve real-time performance of SLAM, fast method proposed in this paper. Firstly, point cloud divided into several regions according to its height, each region projected onto corresponding plane. Then projection plane used as input obtain independent result set. Finally, layer combined get global by...

Since the terrorist attacks have increased over world in recent years, blast-resistant protection of building structures has received considerable attention. The rigid and flexible composite layer as a new measure was examined through method experimental tests this paper. Two sealed steel boxes were selected for testing, one with layer, while other without any protection. rubber material plate is material. effectiveness under different explosive loadings investigated. By comparing structural...

Under the impact loads, once key load-bearing member is damaged, it will endanger entire building structures. Hence, very important to study impact-resistant performance of structural members. In order verify effectiveness a new composite protective device proposed in earlier time, reinforced concrete beam hinged at both ends was choosen as observed object. During process numerical simulation, four different measures including unprotected, rigid, flexible and one were considered sequence....

UHMWPE composites were prepared by hot pressing process with micro-crystal muscovite as reinforced particulates. The mechanical behaviors of to impact loading was evaluated split Hopkinson bar. results demonstrated that dynamic yield stress and failure gradually increased when the filling amount less than 20%; content around 15%, energy absorption efficiency composite reaches maximum value. It also found strain rate within 3200/s, stress, increase display enhancement effect.

Traditional design of structural members is considered less collision effects, so it may be possible to cause damage due impact loads. In view this, impact-resistant performance the composite protective measures proposed in early time was analyzed. process numerical simulation, observed reinforced concrete beams fixed at both ends with four different including unprotected, rigid protective, flexible and one were separately. Protective effects compared analyzed by observing strain, velocity,...

Structural members are vulnerable to be damaged under the impact loads. According traditional design methods, load is seldomly considered. However, recently this situation changed gradually. In view of this, impact-resistant performance a new composite protective device was analyzed. A reinforced concrete beam with laminates, which fixed at one end and hinged other end, studied. Totally, four cases including unprotected, rigid, flexible measures were The effects different can compared by...
