ZM Xiao, O Hauser, C Kirkwood, DZ Li, B Jones… - 2020 - osf.io

… The use of large-scale Randomised Controlled Trials (RCTs) is fast becoming" the gold standard" of testing the causal effects of policy, social, and educational interventions. RCTs are typically evaluated—and ultimately judged—by the economic, educational, and statistical …

Hierarchically structured materials for lithium batteries.

Nanotechnology

Xiao J, Zheng J, Li X, Shao Y, Zhang JG.
PMID: 24067410
Nanotechnology. 2013 Oct 25;24(42):424004. doi: 10.1088/0957-4484/24/42/424004. Epub 2013 Sep 25.

The lithium-ion battery (LIB) is one of the most promising power sources to be deployed in electric vehicles, including solely battery powered vehicles, plug-in hybrid electric vehicles, and hybrid electric vehicles. With the increasing demand for devices of high-energy...

Multi-camera and structured-light vision system (MSVS) for dynamic high-accuracy 3D measurements of railway tunnels.

Sensors (Basel, Switzerland)

Zhan D, Yu L, Xiao J, Chen T.
PMID: 25875190
Sensors (Basel). 2015 Apr 14;15(4):8664-84. doi: 10.3390/s150408664.

Railway tunnel 3D clearance inspection is critical to guaranteeing railway operation safety. However, it is a challenge to inspect railway tunnel 3D clearance using a vision system, because both the spatial range and field of view (FOV) of such...

Stereospecific Synthesis of Tetrahydronaphtho[2,3-b]furans Enabled by a Nickel-Promoted Tandem Reductive Cyclization.

Organic letters

Peng Y, Xiao J, Xu XB, Duan SM, Ren L, Shao YL, Wang YW.
PMID: 27658859
Org Lett. 2016 Oct 07;18(19):5170-5173. doi: 10.1021/acs.orglett.6b02665. Epub 2016 Sep 23.

A Ni-mediated cascade to a stereoselective synthesis of trans-tetrahydronaphtho[2,3-b]furans is efficiently achieved for the first time. The mild reductive system can be easily generated from inexpensive and air-stable materials and shows a broad positional tolerance of substituents that were...

Photocatalytic Radical Trifluoromethylation/Cyclization Cascade: Synthesis of CF3-Containing Pyrazolines and Isoxazolines.

Organic letters

Wei Q, Chen JR, Hu XQ, Yang XC, Lu B, Xiao WJ.
PMID: 26332823
Org Lett. 2015 Sep 18;17(18):4464-7. doi: 10.1021/acs.orglett.5b02118. Epub 2015 Sep 02.

A general visible light induced photoredox-catalyzed radical trifluoromethylation/cyclization cascade of β-aryl-β,γ-unsaturated hydrazones and oximes is described. The protocol enables an efficient access to various densely functionalized and biologically important CF3-containing dihydropyrazoles and isoxazolines with generally high yields.

BACKGROUND: Sodium tanshinone IIA sulfonate (STS) is a water-soluble derivative of tanshinone IIA for treating cardiovascular disorders. The roles of cytochrome P450 enzymes (CYPs) in the metabolism of STS have remained unclear. This study aims to screen the main...

Absence of Exceptional Points in Square Waveguide Arrays with Apparently Balanced Gain and Loss.

Scientific reports

Liu Z, Zhang Q, Liu X, Yao Y, Xiao JJ.
PMID: 26948829
Sci Rep. 2016 Mar 07;6:22711. doi: 10.1038/srep22711.

The concept of parity-time (PT) symmetry in the field of optics has been intensively explored. This study shows the absence of exceptional points in a three-dimensional system composed of a square waveguide array with diagonally-balanced gain/loss distribution. More specifically,...
