This paper presents the modeling, simulation and design guidelines of a high density power inductor for battery power unit (BPU) in order to reduce weight and size especially in automotive applications. A~ 4.5 μH 30A high current density low...

SNPTransformer: a lightweight toolkit for genome-wide association studies.

Genomics, proteomics & bioinformatics

Dong C.
PMID: 21382596
Genomics Proteomics Bioinformatics. 2010 Dec;8(4):268-73. doi: 10.1016/S1672-0229(10)60029-0.

High-throughput genotyping chips have produced huge datasets for genome-wide association studies (GWAS) that have contributed greatly to discovering susceptibility genes for complex diseases. There are two strategies for performing data analysis for GWAS. One strategy is to use open-source...

Photoluminescence, chemiluminescence and anodic electrochemiluminescence of hydrazide-modified graphene quantum dots.

Nanoscale

Dong Y, Dai R, Dong T, Chi Y, Chen G.
PMID: 25132204
Nanoscale. 2014 Oct 07;6(19):11240-5. doi: 10.1039/c4nr02539c.

Single-layer graphene quantum dots (SGQDs) were refluxed with hydrazine (N2H4) to prepare hydrazide-modified SGQDs (HM-SGQDs). Compared with SGQDs, partial oxygen-containing groups have been removed from HM-SGQDs. At the same time, a lot of hydrazide groups have been introduced into...

Quantum Maxwell's demon in thermodynamic cycles.

Physical review. E, Statistical, nonlinear, and soft matter physics

Dong H, Xu DZ, Cai CY, Sun CP.
PMID: 21797303
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):061108. doi: 10.1103/PhysRevE.83.061108. Epub 2011 Jun 08.

We study the physical mechanism of Maxwell's demon (MD), which helps do extra work in thermodynamic cycles with the heat engine. This is exemplified with one molecule confined in an infinitely deep square potential with a movable solid wall....

Successful removal of metal objects causing penile strangulation by a silk winding method.

Case reports in urology

Dong C, Dong Z, Xiong F, Xie Z, Wen Q.
PMID: 24288646
Case Rep Urol. 2013;2013:434397. doi: 10.1155/2013/434397. Epub 2013 Oct 31.

Penile strangulation is a challenge to urologists. The decompression of the penis is required to prevent long-term complications. Metal objects are difficult to remove. Cutting is the most common method described. Appropriate cutting tools may be difficult to obtain,...

Thiol-epoxy click polymerization for preparation of polymeric monoliths with well-defined 3D framework for capillary liquid chromatography.

Analytical chemistry

Lin H, Ou J, Liu Z, Wang H, Dong J, Zou H.
PMID: 25679546
Anal Chem. 2015 Mar 17;87(6):3476-83. doi: 10.1021/acs.analchem.5b00006. Epub 2015 Feb 24.

A facile approach was developed for direct preparation of organic monoliths via the alkaline-catalyzed thiol-epoxy click polymerization. Two organic monoliths were prepared by using tetraphenylolethane glycidyl ether as a multiepoxy monomer, and trimethylolpropane tris(3-mercaptopropionate) and pentaerythritol tetrakis(3-mercaptopropionate) as the...

Tunable Shape Memory Performances via Multilayer Assembly of Thermoplastic Polyurethane and Polycaprolactone.

ACS applied materials & interfaces

Zheng Y, Dong R, Shen J, Guo S.
PMID: 26713358
ACS Appl Mater Interfaces. 2016 Jan 20;8(2):1371-80. doi: 10.1021/acsami.5b10246. Epub 2016 Jan 08.

Shape memory materials containing alternating layers of thermoplastic polyurethane (TPU) and polycaprolactone (PCL) were fabricated through layer-multiplying extrusion. As a type of special co-continuous morphology, the multilayer structure had stable and well-defined continuous layer spaces and could be controlled...
