Hierarchically Porous Networks Structure Based on Flexible SiO2 Nanofibrous Aerogel with Excellent Low Frequency Noise Absorption

SSRN Electronic Journal (2022)

Mengmeng Yang Zhaofeng Chen Lixia Yang Xiaoyang Chen Manna Li

Environmental noise has been regarded as major noise pollutions with severe hazards to human physical and mental health. The common commercial fiber sound-absorption materials have insufficient low frequencies wave absorbing and fire-resistant ability, limiting their wide application. To solve those problem, a novel strategy combining flexible nanofibers and rGO/MXene nanosheets is proposed to fabricate rGO/MXene/SiO 2 nanofibers composite aerogel with hierarchically porous structured, which possess extremely low density of 9.8 mg/cm 3 and superior low-frequency sound absorption ability (NRC value of 0.51). The obtained composite aerogel possessed a large deformation up to 80% with compressive tress of 17KPa, and quickly recover. In addition, the obtained composite aerogel could be easily produced on a large scale, providing a reference for development of new generation of sound absorbing products.

Superconducting 112 MHz QWR electron gun

S. Belomestnykh I. Ben‐Zvi C. Boulware X. Chang Terry Grimm

Brookhaven National Laboratory and Niowave, Inc. have designed and fabricated a superconducting 112 MHz quarter-wave resonator (QWR) electron gun. The first cold test of the QWR cryomodule has been completed at Niowave. The paper describes the cryomodule design, presents the cold test results, and outline plans to upgrade the cryomodule. Future experiments include studies of different photocathodes and use for the coherent electron cooling proof-of-principle experiment. Two cathode stalk options, one for multi-alkali photocathodes and the other one for a diamond-amplified photocathode, are discussed. A quarter-wave resonator concept of superconducting RF (SRF) electron gun was proposed at BNL for electron cooling hadron beams in RHIC. QWRs can be made sufficiently compact even at low RF frequencies (long wavelengths). The long wavelength allows to produce long electron bunches, thus minimizing space charge effects and enabling high bunch charge. Also, such guns should be suitable for experiments requiring high average current electron beams. A 112 MHz QWR gun was designed, fabricated, and cold-tested in collaboration between BNL and Niowave. This is the lowest frequency SRF gun ever tested successfully. In this paper we describe the gun design and fabrication, present the cold test results, and outline our plans. This gun will also serve as a prototype for a future SRF gun to be used for coherent electron cooling of hadrons in eRHIC.

Construction of Chitosan/Graphene Oxide Hybrid Hydrogel Electrode with Conductive Porous Network for High Energy Density Flexible Supercapacitor

SSRN Electronic Journal (2022)

Chen Jiang Mingming Gao Zhang Shou-yun Shitao Yu Lang Huang

The hybrid hydrogel (MCHG) with conductive porous network and heteratomic functional groups are constructed through microwave-assisted hydrothermal, by cross-linking of modified chitosan (M-chitosan) and holey graphene oxide (HGO). Amides and carboxyl groups are introduced during the acylation modification, enabling M-chitosan soluble in water for sufficient reaction. The oxidation etching occurred for graphene oxide in the defect area of substrate by H2O2 provides MCHG with in-plane nanopores, which can provide abundant active surface and short ion diffusion pathway. Due to the high conductivity and flexibility, MCHG can be used as additive-free electrode in three-electrode and it delivers a high specific capacitance of 377 F/g at 5 A/g. The abundant nitrogen and oxygen groups on surface of MCHG can contribute to high capacitance directly. The in-plane nanopores and hierarchically porous network of MCHG is beneficial to improve their wettability, accelerate the charge transfer and enhance their ability of charge storage. When MCHG is adopted into a flexible solid-state supercapacitor using lignin hydrogel electrolyte, it delivers a specific capacitance of 420 F/g at 0.5 A/g, with ultrahigh energy density of 14.8 Wh/kg at the power density of 100 W/kg. The solid-state supercapacitor exhibits promising potential applications in signal sensors and portable energy storage.

Cloning, sequencing analysis and prokaryotic expression of the IGF-I gene from mink.

Zhongguo shengwu gongcheng zazhi (2009)

Rong Min Yang Fu-he Shang‐Zhong Xu Guiwu Wang Xiumei Xing

The sequence of mink IGF-Ⅰgene was obtained and analyzed,and the fusion protein of the IGF-Ⅰ was produced in E.coli.By RT-PCR,liver IGF-Ⅰfrom mink were isolated.The IGF-ⅠcDNAs encoding 153 amino acids,and showed high degree of homology(90%)with other reported sequences(gold monkey,lesser panda,giant panda,A.tiger,horse,et al.)at nucleotide and amino acids levels.Two differences in mink amino acids sequences were found from sequence alignment.Whether these differences affect the molecular conformation or function for the growth factor's processing or these changes in the molecular structure may be responsible for the abnormal ability of growth and reproductive by influencing the function of IGF-Ⅰ have not yet been determined.The DNA fragment encoding the mature peptide of mink IGF-Ⅰwere subcloned to the pGEX-6P-1 expression vector and highly expressed in E.coli.BL21 with IPTG induction.The expression fusion proteins(pGEX-6P-1-IGF-Ⅰ)were mostly existed in soluble form and were about 34kDa.The induced cells culture were proved to be active IGF-Ⅰantigens.The mink IGF-Ⅰ gene was successfully cloned and expressed.Furthermore,the structure and function of this gene were analyzed and predicted.These result provided a good basis for further study of its biological activity.
