Experimental study on wave motion of partial air cushion supported catamaran
Jinglei Yang,Hanbing Sun,Xiaowen Li,Defeng Wu 대한조선학회 2023 International Journal of Naval Architecture and Oc Vol.15 No.-
To study the performance of partial air cushion-supported catamaran (PACSCAT), which is sailing with a flexible air seal in waves, this paper uses the model tests, and research the motion characteristics of PACSCAT at different wavelengths, by monitoring the boundaries of heave, pitch, acceleration, air cushion pressure. Firstly this paper introduces the test situation of PACSCAT in the towing tank and introduces the test method, equipment, and test conditions. Second, this paper extracts the test data, analyzes the features of heave, pitch, acceleration, and air cushion pressure, and studies their linear and nonlinear changes in regular waves. Thirdly this paper analyzes the nonlinear air leakage flow of the bow of PACSCAT in detail under the test conditions and studies the internal and external free liquid surface under different conditions.

One-Pot Synthesis of Zincblende CuInSe2 Nanocrystals via a Green Solution Reaction Route
Dehui Li,Weichen Qi,Jinglei Xiao,Jing Yang,Yong Wu,Qiao Gao,Shengyong Zhai 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2017 NANO Vol.12 No.9
The facile and ecofriendly method for the synthesis of a suitable colloidal nanocrystal ink plays an important role in the field of solar cells. Here, we describe our recent efforts toward this direction by a simple one-pot colloidal method to engineer CuInSe2 (CISe) nanocrystals with cubic zinc-blende (ZB) structure. The suitable band gap value and obvious photoresponse of the as-synthesized CISe nanocrystals indicate their potential application in the field of thin film solar cells. In addition, a possible crystal growth mechanism has been suggested for the formation of ZB CISe.

Facilely tuning the surface wettability of Cu mesh for multi-functional applications
Xingwang Zhao,Fei Mao,Jiayue Wu,Jinglei Lei,Lingjie Li 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.116 No.-
The Cu meshes with reversible super-wettability have multifunctions of self-cleaning, oil–water separation,floating-oil collection and underwater oil lossless-transportation. However, the facile method totune the surface wettability and prepare reversibly super-wetting Cu meshes remains a great challenge. In this work, one-step chemical-etching method was used to construct the hierarchically-structured CuOof nano-sheets and micro-clusters on Cu meshes to provide suitable surface roughness essential forsuper-wettability. The surface wettability of Cu mesh was then facilely tuned by controlling the adsorptionand desorption of C-containing species at the Cu mesh surface through C-rich ambience storage andIR irradiation for short duration. The super-wetting transition of Cu meshes betweensuperhydrophobicity/superoleophilicity and superhydrophilicity/underwater-superoleophobicity couldrepeat for many cycles. Moreover, the super-wetting Cu meshes demonstrated excellent mechanical,physical and chemical stabilities. The switchable super-wettability endowed the Cu meshes with integratedmulti-functions, which demonstrated remarkable performance of self-cleaning, oil–water separation,floating-oil collection and underwater oil lossless-transportation. This study suggests that utilizingC-rich ambience storage and IR irradiation to control the content of C-containing species at the Cu meshsurface is a facile and effective way to tune the surface wettability of Cu meshes, which can be easilyextended to realize super-wettability transition of various materials.

Electrospun SrO-Incorporated Nanofiber Membranes for Biomedical Applications
Zhe Chen,Jitao Fan,Yangfan Ding,Yunlong Zhang,Ahmed I. Abd‑Elhamid,Jinglei Wu,Binbin Sun 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11
Bioactive ceramics have gained increasing interest in biomedical applications. Strontium (Sr)-based ceramics show unique bioactivity in stimulating cell proliferation and migration and promoting angiogenesis. Incorporation of bioactive ceramics into nanofibers represents a facile approach to alter the material properties of electrospun nanofiber membranes. Herein, we prepared SrO-incorporated nanofiber membranes by electrospinning and investigated the effects of SrO particles on the physicochemical properties and cytocompatibility of these membranes. Our results indicate that simple one-stream electrospinning could smoothly introduce SrO particles into poly(L-lactic acid) (PLA)/gelatin nanofibers. SrO-incorporated membranes showed significantly improved wettability but became brittle compared with PLA/gelatin nanofiber membranes. Cells differentially responded to SrO-incorporated membranes: endothelial cells showed greater cell area and coverage on SrO-incorporated membranes; in contrast, fibroblasts were inhibited on these membranes. These findings suggest that SrO-incorporated membranes might find opportunities in specific biomedical applications in which pro-angiogenesis and antiadhesion are simultaneously demanded.
