Graphene-to-substrate energy transfer through out-of-plane longitudinal acoustic phonons.

Nano letters

Chen IJ, Mante PA, Chang CK, Yang SC, Chen HY, Huang YR, Chen LC, Chen KH, Gusev V, Sun CK.
PMID: 24559107
Nano Lett. 2014 Mar 12;14(3):1317-23. doi: 10.1021/nl404297r. Epub 2014 Mar 03.

Practically, graphene is often deposited on substrates. Given the major substrate-induced modification of properties and considerable energy transfer at the interface, the graphene-substrate interaction has been widely discussed. However, the proposed mechanisms were restricted to the two-dimensional (2D) plane...

Organometallic-route synthesis, controllable growth, mechanism investigation, and surface feature of PbSe nanostructures with tunable shapes.

Langmuir : the ACS journal of surfaces and colloids

Shao G, Chen G, Yang W, Ding T, Zuo J, Yang Q.
PMID: 24559144
Langmuir. 2014 Mar 18;30(10):2863-72. doi: 10.1021/la4042869. Epub 2014 Mar 07.

Lead selenide (PbSe) nanostructures with well-defined star-shaped morphology are successfully fabricated via a facile organometallic synthetic route from the reaction of tetraphenyl lead (Ph4Pb) with triphenylphosphine selenide (Ph3PSe) in dibenzylamine (DBA) with the assistance of oleic acid (OA) and...

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...

Estimation of the electron affinities of C60, corannulene, and coronene by using the kinetic method.

Journal of the American Society for Mass Spectrometry

Chen G, Cookscor RG, Corpuz E, Scott LT.
PMID: 24203477
J Am Soc Mass Spectrom. 1996 Jul;7(7):619-27. doi: 10.1016/1044-0305(96)85610-8.

Novel anions that contain one molecule each of C60 and the polycyclic aromatic hydrocarbon coronene are generated in the gas phase by electron attachment desorption chemical ionization. Collision-induced dissociation reveals that these cluster ions are loosely bonded. Fragmentation of...

Patterning of high-quality two-dimensional chalcogenide crystals with unique planar structures and various fascinating electronic properties offers great potential for batch fabrication and integration of electronic and optoelectronic devices. However, it remains a challenge that requires accurate control of the...

Tunable spin-orbit coupling and quantum phase transition in a trapped Bose-Einstein condensate.

Scientific reports

Zhang Y, Chen G, Zhang C.
PMID: 23727689
Sci Rep. 2013;3:1937. doi: 10.1038/srep01937.

Spin-orbit coupling (SOC), the intrinsic interaction between a particle spin and its motion, is responsible for various important phenomena, ranging from atomic fine structure to topological condensed matter physics. The recent experimental breakthrough on the realization of SOC for...

Tailoring high-temperature radiation and the resurrection of the incandescent source.

Nature nanotechnology

Ilic O, Bermel P, Chen G, Joannopoulos JD, Celanovic I, Soljačić M.
PMID: 26751172
Nat Nanotechnol. 2016 Apr;11(4):320-4. doi: 10.1038/nnano.2015.309. Epub 2016 Jan 11.

In solar cells, the mismatch between the Sun's emission spectrum and the cells' absorption profile limits the efficiency of such devices, while in incandescent light bulbs, most of the energy is lost as heat. One way to avoid the...

TLR4 antagonist suppresses airway remodeling in asthma by inhibiting the T-helper 2 response.

Experimental and therapeutic medicine

Li M, Wang ZN, Yang LF, Yan Y, Cai LM, Li YT, Qiao YK, Chen ZG.
