Exceptionally large second-order nonlinear optical response in donor-graphene nanoribbon-acceptor systems.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhou ZJ, Li XP, Ma F, Liu ZB, Li ZR, Huang XR, Sun CC.
PMID: 21319235
Chemistry. 2011 Feb 18;17(8):2414-9. doi: 10.1002/chem.201001727. Epub 2011 Jan 07.

Graphene nanoribbon (GNR) has been used, for the first time, as an excellent conjugated bridge in a donor-conjugated bridge-acceptor (D-B-A) framework to design high-performance second-order nonlinear optical materials. Owing to the unique diradical planar conjugated bridge of GNR, D(NH(2))-GNR-A(NO(2))...

Structures of Pb(n) (n = 21-30) clusters from first-principles calculations.

Journal of physics. Condensed matter : an Institute of Physics journal

Li XP, Lu WC, Wang CZ, Ho KM.
PMID: 21403370
J Phys Condens Matter. 2010 Nov 24;22(46):465501. doi: 10.1088/0953-8984/22/46/465501. Epub 2010 Oct 29.

Neutral lead clusters Pb(n) (n = 21-30) were studied using a genetic algorithm (GA)/tight-binding (TB) search combined with density functional theory (DFT)-Perdew-Burke-Ernzerhof (PBE) calculations. The calculated results show that the Pb(n) (22 ≤ n ≤ 30) clusters favor endohedral...

Identification of adsorbed molecules via STM tip manipulation: CO, H₂O, and O₂ on TiO₂ anatase (101).

Physical chemistry chemical physics : PCCP

Setvin M, Daniel B, Aschauer U, Hou W, Li YF, Schmid M, Selloni A, Diebold U.
PMID: 25186563
Phys Chem Chem Phys. 2014 Oct 21;16(39):21524-30. doi: 10.1039/c4cp03212h. Epub 2014 Sep 04.

While Scanning Tunneling Microscopy (STM) has evolved as an ideal tool to study surface chemistry at the atomic scale, the identification of adsorbed species is often not straightforward. This paper describes a way to reliably identify H2O, CO and...

Topological insulators with SU(2) Landau levels.

Physical review letters

Li Y, Zhang SC, Wu C.
PMID: 24237548
Phys Rev Lett. 2013 Nov 01;111(18):186803. doi: 10.1103/PhysRevLett.111.186803. Epub 2013 Oct 30.

We construct continuum models of 3D and 4D topological insulators by coupling spin-1/2 fermions to an SU(2) background gauge field, which is equivalent to a spatially dependent spin-orbit coupling. Higher dimensional generalizations of flat Landau levels are obtained in...

New Labdane diterpenes from Hedychium yunnanense with cytotoxicity and inhibitory effects on nitric oxide production.

Natural product research

PMID: 26965832
Nat Prod Res. 2016 Dec;30(23):2669-2674. doi: 10.1080/14786419.2016.1143829. Epub 2016 Mar 11.

Two new labdane diterpenes, hedychenoids A (1) and B (2), were isolated from the rhizomes of Hedychium yunnanense, together with four known ones hedychenone (3), forrestin A (4), villosin (5) and calcaratarin C (6). Their structures were determined on...

In situ measurement of the two-dimensional temperature field of a dual-jet direct-current arc plasma.

The Review of scientific instruments

Guo H, Li P, Li HP, Ge N, Bao CY.
PMID: 27036772
Rev Sci Instrum. 2016 Mar;87(3):033502. doi: 10.1063/1.4942965.

In this paper, a real time method for an in situ measurement of the two-dimensional (2-D) temperature filed of thermal plasmas is developed with the combination of the visible image processing technique and the spectroscopic line-ratio method at two...

Adaptive Control via Neural Output Feedback for a Class of Nonlinear Discrete-Time Systems in a Nested Interconnected Form.

IEEE transactions on cybernetics

Li DJ, Li DP.
PMID: 28920913
IEEE Trans Cybern. 2018 Sep;48(9):2633-2642. doi: 10.1109/TCYB.2017.2747628. Epub 2017 Sep 14.

In this paper, an adaptive output feedback control is framed for uncertain nonlinear discrete-time systems. The considered systems are a class of multi-input multioutput nonaffine nonlinear systems, and they are in the nested lower triangular form. Furthermore, the unknown...

Molecular recircumscription of Broussonetia (Moraceae) and the identity and taxonomic status of B. kaempferi var. australis.

BACKGROUND: Despite being a relatively small genus, the taxonomy of the paper mulberry genus Broussonetia remains problematic. Much of the controversy is related to the identity and taxonomic status of Broussonetia kaempferi var. australis, a name treated as a...

Macrodeformation Twins in Single-Crystal Aluminum.

Physical review letters

Zhao F, Wang L, Fan D, Bie BX, Zhou XM, Suo T, Li YL, Chen MW, Liu CL, Qi ML, Zhu MH, Luo SN.

Deformation twinning in pure aluminum has been considered to be a unique property of nanostructured aluminum. A lingering mystery is whether deformation twinning occurs in coarse-grained or single-crystal aluminum at scales beyond nanotwins. Here, we present the first experimental...
