Growth of hydrophilic CuS nanowires via DNA-mediated self-assembly process and their use in fabricating smart hybrid films for adjustable chemical release.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhou L, Li W, Chen Z, Ju E, Ren J, Qu X.
PMID: 25504567
Chemistry. 2015 Feb 09;21(7):2930-5. doi: 10.1002/chem.201405796. Epub 2014 Dec 11.

Facile growth of CuS nanowires through self-assembly and their application as building blocks for near-infrared light-responsive functional films have been demonstrated. It is found that DNA is a key factor in preparing the CuS material with defined nanostructure. An...

A novel copper-rich open-framework chalcogenide constructed from octahedral Cu4Se6 and icosahedral Cu8Se13 nanoclusters.

Chemical communications (Cambridge, England)

Yang H, Wang L, Hu D, Lin J, Luo L, Wang H, Wu T.
PMID: 26857029
Chem Commun (Camb). 2016 Mar 18;52(22):4140-3. doi: 10.1039/c6cc00183a.

We demonstrated a unique copper-rich open-framework chalcogenide constructed from icosahedral Cu8Se13 and octahedral Cu4Se6 nanoclusters connected to each other through a SnSe3(Se2) bridging unit. The specific copper-rich composition gives rise to a narrow band gap and photoelectrical responsive properties...

Cu2O-templated strategy for synthesis of definable hollow architectures.

Chemical communications (Cambridge, England)

Sun S, Yang Z.
PMID: 24728137
Chem Commun (Camb). 2014 Jul 18;50(56):7403-15. doi: 10.1039/c4cc00304g.

The template-strategy is one of the most significant techniques for the controllable synthesis of hollow architectures with unique structures, morphologies and properties. In this review, we selectively summarize the general principles of the Cu2O-templated strategy for the synthesis of...

Enhanced nonlinear optical characteristics of copper-ion-doped double crossover DNAs.

Nanoscale

Park B, Lee BJ, Dugasani SR, Cho Y, Kim C, Seo M, Lee T, Jhon YM, Choi J, Lee S, Park SH, Jun SC, Yeom DI, Rotermund F, Kim JH.
PMID: 26469873
Nanoscale. 2015 Nov 21;7(43):18089-95. doi: 10.1039/c5nr05075h.

The modification of deoxyribonucleic acid (DNA) samples by sequencing the order of bases and doping copper ions opens the possibility for the design of novel nanomaterials exhibiting large optical nonlinearity. We investigated the nonlinear characteristics of copper-ion doped double...

A smart magnetic resonance contrast agent for selective copper sensing.

Journal of the American Chemical Society

Que EL, Chang CJ.
PMID: 17165700
J Am Chem Soc. 2006 Dec 20;128(50):15942-3. doi: 10.1021/ja065264l.

We describe the synthesis and properties of Copper-Gad-1 (CG1), a new type of smart magnetic resonance (MR) sensor for selective detection of copper. CG1 is composed of a gadolinium contrast agent core tethered to copper-selective recognition motif. Cu2+-induced modulation...

Quantitative determination of pairing interactions for high-temperature superconductivity in cuprates.

Science advances

Bok JM, Bae JJ, Choi HY, Varma CM, Zhang W, He J, Zhang Y, Yu L, Zhou XJ.
PMID: 26973872
Sci Adv. 2016 Mar 04;2(3):e1501329. doi: 10.1126/sciadv.1501329. eCollection 2016 Mar.

A profound problem in modern condensed matter physics is discovering and understanding the nature of fluctuations and their coupling to fermions in cuprates, which lead to high-temperature superconductivity and the invariably associated strange metal state. We report the quantitative...

A multivalent mixed-metal strategy for single-Cu.

Chemical communications (Cambridge, England)

Zhang J, Wang X, Lv J, Li DS, Wu T.
PMID: 31065633
Chem Commun (Camb). 2019 May 30;55(45):6357-6360. doi: 10.1039/c9cc02905b.

Here we report two new metal-chalcogenide open frameworks (MCOFs) with large-sized supertetrahedral clusters bridged by an accessible single-cuprous ion via a multivalent mixed-metal strategy. Such Cu-rich semiconductor MCOFs have been investigated for the first time for nonenzymatic detection of...

Effect of sample preparation on contaminant leaching from copper smelting slag.

Journal of hazardous materials

Vítková M, Ettler V, Mihaljevič M, Sebek O.
PMID: 22030274
J Hazard Mater. 2011 Dec 15;197:417-23. doi: 10.1016/j.jhazmat.2011.09.102. Epub 2011 Oct 06.

Currently standardised leaching tests require grain size reduction, which for large fragments of slags could overestimate the leaching results. To assess the effect of the fine-grained fraction generated by sample crushing, a set of leaching experiments was performed on...
