“…In the manner of CO 3 2− doping, carbon was successfully introduced into an anatase photocatalyst by Sakthivel and Kisch. 21 Wang et al 22 also found a typical narrowed band gap of fibrous TiO 2 of 0.7 eV while C doping of TiO 2 blocks. As well, the visible light response of C-doped TiO 2 has been evidenced experimentally.…”

A C@Ti/anatase nanoporous fiber, where C ions replace the positions of Ti (1-5%) in the lattice, was prepared quasi-in situ by electrospinning a titanate gel containing a polyethylene-polypropylene glycol additive. Compared with immobilized nano-TiO2 and anatase fibers, C@Ti/anatase fibers showed improved optical absorption for visible light. The improved photocatalytic activity of the fibers was further testified by its decomposition of 2,4,6-trichlorophenol (TCP) and methyl orange (MO) under visible light irradiation. The strengthened optical absorptivity was attributed to modifying the energy band structure in the lattice of anatase which results from isotropic and anisotropic stress. Based on analysis by first principle theory calculations, the C@Ti/anatase has been evidenced to be "softer" than the pure anatase ones, and easily affected by micro-residual stress. The lattice parameters of the C@Ti/anatase fibers became distorted when anisotropic compressive stresses were applied, resulting in a narrowed band gap.

“…Dennard Scaling began to slow significantly in 2007 and faded to almost nothing by 2012, as shown in Figure 9 (reproduced with permission from [49]). Since 2007, this scaling effect has slowed down until 2012 when the power consumption per square nanometer began to rise rapidly, resulting in an increase in energy consumption and a decrease in efficiency [50][51][52]. Power consumption has become a major challenge for chip design.…”

“…Each interconnect interface integrates one to multiple high-speed SerDes, and the transmission performance of a single SerDes has been rapidly improved from the early 1.25 Gbps to 50 Gbps. SerDes bandwidth continues to increase, enabling high-performance chips to achieve higher throughput with fewer chip pins, and it has been driving interconnection networks to higher bandwidths for many years [52]. The performance of SerDes continues to improve, but in recent years, the SerDes power consumption per bit required to transmit has decreased slowly.…”

High-performance interconnection network is the key to realizing high-speed, collaborative, parallel computing at each node in a high-performance computer system. Its performance and scalability directly affect the performance and scalability of the whole system. With continuous improvements in the performance of high-performance computer systems, the trend in the development of high-performance interconnection networks is mainly reflected in network sizes and network bandwidths. With the slowdown of Moore’s Law, it is necessary to adopt new packaging design technologies to implement high-performance interconnection networks for high-performance computing. This article analyzes the main interconnection networks used by high-performance computer systems in the Top500 list of November 2021, and it elaborates the design of representative, state-of-the-art, high-performance interconnection networks, including NVIDIA InfiniBand, Intel Omni-Path, Cray Slingshot/Aries, and custom or proprietary networks, including Fugaku Tofu, Bull BXI, TH Express, and so forth. This article also comprehensively discusses the latest technologies and trends in this field. In addition, based on the analysis of the challenges faced by high-performance interconnection network design in the post-Moore era and the exascale computing era, this article presents a perspective on high-performance interconnection networks.

“…However, pure anatase shows photocatalytic activity only under ultraviolet light irradiation due to its wide band gap (3.2 eV), which leads to a low solar energy utilization. Many attempts have been made to improve the photocatalytic performance of TiO 2 photoanode for DSSCs by doping non-metal elements such as N, C and S [8][9][10]. For the N-doped TiO 2 photoanodes, improvement of both the open circuit voltage and the visible absorption [8], have been reported and high conversion efficiency has been recorded.…”
