Oncotarget. 2017 May 31;8(35):59901-59914. doi: 10.18632/oncotarget.18316. eCollection 2017 Aug 29.

BACKGROUND: PD-1/PD-L1 inhibitors have been implicated as potentially effective anti-cancer therapies. Some clinical randomized controlled trials (RCTs) have been completed for a variety of PD-1/PD-L1 inhibitors to treat various malignancies, and more RCTs are still under way. We carried...

Insight into the phase evolution of a NiMgAl catalyst from the reduction stage to the post-reaction stage during the dry reforming of methane.

Chemical communications (Cambridge, England)

Bao Z, Zhan Y, Street J, Xu W, To F, Yu F.
PMID: 28516177
Chem Commun (Camb). 2017 May 30;53(44):6001-6004. doi: 10.1039/c7cc03094k.

Herein, phase evolution of a NiMgAl oxide catalyst at the reduction stage was qualitatively analysed and quantitatively determined by employing the continuous changes in its XRD intensity and TPR information. The stable crystallite size of both the active metal...

Error Propagation Dynamics of PIV-based Pressure Field Calculations: How well does the pressure Poisson solver perform inherently?.

Measurement science & technology

Pan Z, Whitehead J, Thomson S, Truscott T.
PMID: 27499587
Meas Sci Technol. 2016 Aug;27(8):084012. doi: 10.1088/0957-0233/27/8/084012. Epub 2016 Jul 06.

Obtaining pressure field data from particle image velocimetry (PIV) is an attractive technique in fluid dynamics due to its noninvasive nature. The application of this technique generally involves integrating the pressure gradient or solving the pressure Poisson equation using...

A Single-Molecular AND Gate Operated with Two Orthogonal Switching Mechanisms.

Advanced materials (Deerfield Beach, Fla.)

Zhang N, Lo WY, Jose A, Cai Z, Li L, Yu L.
PMID: 28512786
Adv Mater. 2017 Jul;29(28). doi: 10.1002/adma.201701248. Epub 2017 May 17.

Single-molecular electronics is a potential solution to nanoscale electronic devices. While simple functional single-molecule devices such as diodes, switches, and wires are well studied, complex single-molecular systems with multiple functional units are rarely investigated. Here, a single-molecule AND logic...

Carbon-Doped BN Nanosheets for the Oxidative Dehydrogenation of Ethylbenzene.

Angewandte Chemie (International ed. in English)

Guo F, Yang P, Pan Z, Cao XN, Xie Z, Wang X.
PMID: 28514048
Angew Chem Int Ed Engl. 2017 Jul 03;56(28):8231-8235. doi: 10.1002/anie.201703789. Epub 2017 Jun 12.

Carbon-based catalysts have demonstrated great potential for the aerobic oxidative dehydrogenation reaction (ODH). However, its widespread application is retarded by the unavoidable deactivation owing to the appearance of coking or combustion under ODH conditions. The synthesis and characterization of...

Chirality Inversion of CdSe and CdS Quantum Dots without Changing the Stereochemistry of the Capping Ligand.

ACS nano

Choi JK, Haynie BE, Tohgha U, Pap L, Elliott KW, Leonard BM, Dzyuba SV, Varga K, Kubelka J, Balaz M.

L-cysteine derivatives induce and modulate the optical activity of achiral cadmium selenide (CdSe) and cadmium sulfide (CdS) quantum dots (QDs). Remarkably, N-acetyl-L-cysteine-CdSe and L-homocysteine-CdSe as well as N-acetyl-L-cysteine-CdS and L-cysteine-CdS showed "mirror-image" circular dichroism (CD) spectra regardless of the...

First Detection of the Acoustic Oscillation Phase Shift Expected from the Cosmic Neutrino Background.

Physical review letters

Follin B, Knox L, Millea M, Pan Z.
PMID: 26371637
Phys Rev Lett. 2015 Aug 28;115(9):091301. doi: 10.1103/PhysRevLett.115.091301. Epub 2015 Aug 26.

The unimpeded relativistic propagation of cosmological neutrinos prior to recombination of the baryon-photon plasma alters gravitational potentials and therefore the details of the time-dependent gravitational driving of acoustic oscillations. We report here a first detection of the resulting shifts...
