Hong Y, Ren G, Liu E.
PMID: 26368490
Opt Express. 2015 Sep 07;23(18):23992-4003. doi: 10.1364/OE.23.023992.

This paper presents a new and effective technique to calibrate a camera without nonlinear iteration optimization. To this end, the centre-of-distortion is accurately estimated firstly. Based on the radial distortion division model, point correspondences between model plane and its...

In this letter, we present a sapphire direct bonding method using plasma surface activation, hydrophilic pre-bonding, and high temperature annealing. Through the combination of sapphire inductively coupled plasma etching and the direct bonding process, a vacuum-sealed cavity employable for...

Observation of Magnetoelectric Multiferroicity in a Cubic Perovskite System: LaMn(3)Cr(4)O(12).

Physical review letters

Wang X, Chai Y, Zhou L, Cao H, Cruz CD, Yang J, Dai J, Yin Y, Yuan Z, Zhang S, Yu R, Azuma M, Shimakawa Y, Zhang H, Dong S, Sun Y, Jin C, Long Y.
PMID: 26340207
Phys Rev Lett. 2015 Aug 21;115(8):087601. doi: 10.1103/PhysRevLett.115.087601. Epub 2015 Aug 18.

Magnetoelectric multiferroicity is not expected to occur in a cubic perovskite system because of the high structural symmetry. By versatile measurements in magnetization, dielectric constant, electric polarization, neutron and x-ray diffraction, Raman scattering, as well as theoretical calculations, we...

Effects of foliar application of salicylic acid and nitric oxide in alleviating iron deficiency induced chlorosis of Arachis hypogaea L.

Botanical studies

Fan X, Zheng W, Liu H, Zhuang X, Fan P, Gong Y, Li H, Wu X, Jiang Y, Zhu X, Zhang Q, Zhou H, Hu W, Wang X, Duan X, Pan A.
PMID: 28513703
Nanoscale. 2017 Jun 01;9(21):7235-7241. doi: 10.1039/c7nr01345k.

Recombination dynamics during photoluminescence (PL) in two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) are complicated and can be easily affected by the surroundings because of their atomically thin structures. Herein, we studied the excitation power and temperature dependence of...
