Improved Drain Current Saturation and Voltage Gain in Graphene-on-Silicon Field Effect Transistors.

Scientific reports

Song SM, Bong JH, Hwang WS, Cho BJ.
PMID: 27142861
Sci Rep. 2016 May 04;6:25392. doi: 10.1038/srep25392.

Graphene devices for radio frequency (RF) applications are of great interest due to their excellent carrier mobility and saturation velocity. However, the insufficient current saturation in graphene field effect transistors (FETs) is a barrier preventing enhancements of the maximum...

Emulsified isoflurane anesthesia decreases brain-derived neurotrophic factor expression and induces cognitive dysfunction in adult rats.

Experimental and therapeutic medicine

Zhang F, Zhu ZQ, Liu DX, Zhang C, Gong QH, Zhu YH.
PMID: 25009603
Exp Ther Med. 2014 Aug;8(2):471-477. doi: 10.3892/etm.2014.1769. Epub 2014 Jun 10.

Post-operative cognitive dysfunction (POCD) is a severe complication characterized by cognitive decline in patients following anesthesia and surgery. Previous studies have suggested that volatile anesthetics, for example isoflurane, may contribute to such impairment. In the present study, the effects...

Acetylated bovine serum albumin differentially inhibits polymerase chain reaction in microdevices.

Biomicrofluidics. 2017 May 17;11(3):034110. doi: 10.1063/1.4983692. eCollection 2017 May.

Bovine serum albumin (BSA) is widely used as an additive in polymerase chain reaction (PCR)-based microfluidic devices to passivate reactors and alleviate nucleic-acid amplification. BSA is available commercially in two types: either acetylated or non-acetylated. A survey of literature...

Asymmetric Total Synthesis of Distaminolyne A and Revision of Its Absolute Configuration.

Organic letters

Sun DY, Han GY, Gong JX, Nay B, Li XW, Guo YW.
PMID: 28111958
Org Lett. 2017 Feb 03;19(3):714-717. doi: 10.1021/acs.orglett.6b03892. Epub 2017 Jan 23.

The first total synthesis of a marine derived polyacetylene, distaminolyne A, and its enantiomer were achieved from the commercially available undec-10-en-1-ol. A key proline-catalyzed asymmetric α-aminooxylation of an aldehyde intermediate was used to introduce the chiral center en route...

J Cheminform. 2017 Jan 05;9:2. doi: 10.1186/s13321-016-0188-5. eCollection 2017.

BACKGROUND: Natural products have increasingly attracted much attention as a valuable resource for the development of anticancer medicines due to the structural novelty and good bioavailability. This necessitates a comprehensive database for the natural products and the fractional extracts...

Genome-wide analysis of the CaHsp20 gene family in pepper: comprehensive sequence and expression profile analysis under heat stress.

Frontiers in plant science

Guo M, Liu JH, Lu JP, Zhai YF, Wang H, Gong ZH, Wang SB, Lu MH.
PMID: 26483820
Front Plant Sci. 2015 Oct 01;6:806. doi: 10.3389/fpls.2015.00806. eCollection 2015.

The Hsp20 genes are present in all plant species and play important roles in alleviating heat stress and enhancing plant thermotolerance by preventing the irreversible aggregation of denaturing proteins. However, very little is known about the CaHsp20 gene family...

In situ observation of a hydrogel-glass interface during sliding friction.

Soft matter

Yamamoto T, Kurokawa T, Ahmed J, Kamita G, Yashima S, Furukawa Y, Ota Y, Furukawa H, Gong JP.
PMID: 24962139
Soft Matter. 2014 Aug 14;10(30):5589-96. doi: 10.1039/c4sm00338a.

Direct observation of hydrogel contact with a solid surface in water is indispensable for understanding the friction, lubrication, and adhesion of hydrogels under water. However, this is a difficult task since the refractive index of hydrogels is very close...
