Test of genuine multipartite nonlocality without inequalities.

Physical review letters

Chen Q, Yu S, Zhang C, Lai CH, Oh CH.
PMID: 24765926
Phys Rev Lett. 2014 Apr 11;112(14):140404. doi: 10.1103/PhysRevLett.112.140404. Epub 2014 Apr 10.

In this Letter we propose a set of conditions on the joint probabilities as a test of genuine multipartite nonlocality without inequality. Our test is failed by all nonsignaling local models in which even nonlocal correlations among some observables...

The intrinsic origin of hysteresis in MoS2 field effect transistors.

Nanoscale

Shu J, Wu G, Guo Y, Liu B, Wei X, Chen Q.
PMID: 26782750
Nanoscale. 2016 Feb 07;8(5):3049-56. doi: 10.1039/c5nr07336g.

We investigate the hysteresis and gate voltage stress effect in MoS2 field effect transistors (FETs). We observe that both the suspended and the SiO2-supported FETs have large hysteresis in their transfer curves under vacuum which cannot be attributed to...

PMID: 24847850
Nanotechnology. 2014 Jun 13;25(23):235401. doi: 10.1088/0957-4484/25/23/235401. Epub 2014 May 21.

A three-dimensional (3D) carbon quantum dot (CQD) aerogel has been prepared by in situ assembling CQDs in the sol-gel polymerization of resorcinol (R) and formaldehyde (F) and subsequently pyrolyzing the formed CQD gel. Compared to the supercapacitor based on...

Abnormal gas-liquid-solid phase transition behaviour of water observed with in situ environmental SEM.

Scientific reports

Chen X, Shu J, Chen Q.
PMID: 28436421
Sci Rep. 2017 Apr 24;7:46680. doi: 10.1038/srep46680.

Gas-liquid-solid phase transition behaviour of water is studied with environmental scanning electron microscopy for the first time. Abnormal phenomena are observed. At a fixed pressure of 450 Pa, with the temperature set to -7 °C, direct desublimation happens, and...

Unique structural micro-adjustments in a new benzothiadiazole-derived Zn(ii) metal organic framework via simple photochemical decarboxylation.

Chemical communications (Cambridge, England)

PMID: 28872178
Chem Commun (Camb). 2017 Sep 14;53(74):10314-10317. doi: 10.1039/c7cc06125k.

The first example of micro-adjustments of a metal organic framework (MOF) structure was observed in a new Zn(ii) MOF (Zn-BTDC-M1) derived from a benzothiadiazole-4,7-dicarboxylic acid (H
