Engineering the grain boundary: a promising strategy to configure NiCoPO/NiCoP nanowire arrays for ultra-stable

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 8,   Pages 1259-1267 doi: 10.1007/s11705-021-2132-0

Abstract: NiCoP4O12/NiCoP nanorod-like arrays with tunable grain boundary density and pores were synthesized by the processes composed of hydrothermal and pyrolysis, in which, the electron structure of Ni and Co atoms characterized by X-ray photoelectron spectroscopy was contemporaneous inverse manipulated. The optimized NiCoP4O12/NiCoP arrays have a high specific capacitance of 507.8 μAh∙cm–2 at 1 mA∙cm–2, and good rate ability of 64.7% retention at 30-folds increased current density. Importantly, an ultra-stable ability, 88.5% of retention after 10000 cycles, was achieved in an asymmetric cell assembled of the NiCoP4O12/NiCoP arrays with activated carbon. In addition, the energy and power densities of an asymmetric cell were higher than those of other work, demonstrating as-prepared NiCoP4O12/NiCoP arrays are promising electrodes for supercapacitors.

Resolving the Adhesive Behavior of 1D Materials: A Review of Experimental Approaches Review

James L. Mead, Shiliang Wang, Sören Zimmermann, Sergej Fatikow, Han Huang

Engineering 2023, Volume 24, Issue 5,   Pages 39-72 doi: 10.1016/j.eng.2023.02.012

Abstract:

The adhesive behavior of one-dimensional (1D) materials, such as nanotubes and nanowires, plays a decisive role in the effective fabrication, functionality, and reliability of novel devices that integrate 1D components, as well as in biomimetic adhesives based on 1D arrays. This review compiles and critically evaluates recent experimental techniques that aim to characterize the adhesion behavior of interfaces formed by 1D materials, including when such materials are brought into contact with a substrate or adjacent 1D materials. The conformation of 1D material to surfaces and the associated occurrence of multi-asperity contact are discussed, and the coupling of adhesion and friction during interfacial attachment and detachment is explored. The use of 1D materials as reinforcement agents in nanocomposites and the associated interfacial characterization techniques are considered. The potential for the environmental conditions that exist during sample preparation and adhesion testing to influence 1D interfacial interactions and, ultimately, to alter the adhesion behavior of a 1D material is scrutinized. Finally, a brief perspective is provided on ongoing challenges and future directions, which include the methodical investigation of the testing environment and the alteration of adhesion through surface modification.

Wideband cryogenic amplifier for a superconducting nanowire single-photon detector Research Article

Lianming Li, Long He, Xu Wu, Xiaokang Niu, Chao Wan, Lin Kang, Xiaoqing Jia, Labao Zhang, Qingyuan Zhao, Xuecou Tu,Lianming.LI@seu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 12,   Pages 1551-1684 doi: 10.1631/FITEE.2100525

Abstract: We present a low-power inductorless wideband differential using a 0.13-μm SiGe BiCMOS process for a . With a shunt–shunt feedback and capacitive coupling structure, theoretical analysis and simulations were undertaken, highlighting the relationship of the amplifier gain with the tunable design parameters of the circuit. In this way, the design and optimization flexibility can be increased, and a required gain can be achieved even without an accurate cryogenic device model. To realize a flat terminal impedance over the frequency of interest, an RC shunt compensation structure was employed, improving the amplifier’s closed-loop stability and suppressing the amplifier overshoot. The -parameters and transient performance were measured at room temperature (300 K) and cryogenic temperature (4.2 K). With good input and output matching, the measurement results showed that the amplifier achieved a 21-dB gain with a 3-dB bandwidth of 1.13 GHz at 300 K. At 4.2 K, the gain of the amplifier can be tuned from 15 to 24 dB, achieving a 3-dB bandwidth spanning from 120 kHz to 1.3 GHz and consuming only 3.1 mW. Excluding the chip pads, the amplifier chip core area was only about 0.073 mm.
