Carbon-Dot-Based Ratiometric Fluorescent Probe for Imaging and Biosensing of Superoxide Anion in Live Cells

Xiang Gao、Changqin Ding、Anwei Zhu 等 4 位作者2014-06-16Analytical Chemistry

In this article, a ratiometric fluorescent biosensor for O2(•-) was developed, by employing carbon dots (C-Dots) as the reference fluorophore and hydroethidine (HE), a specific organic molecule toward O2(•-), playing the role as both specific recognition element and response signal. The hybrid fluorescent probe CD-HE…

Chiral Liquid Crystals: Structures, Phases, Effects

Ingo Dierking2014-06-16Symmetry

The introduction of chirality, i.e., the lack of mirror symmetry, has a profound effect on liquid crystals, not only on the molecular scale but also on the supermolecular scale and phase. I review these effects, which are related to the formation of supermolecular helicity, the occurrence of novel thermodynamic phases…

The Effect of Salt on the Complex Coacervation of Vinyl Polyelectrolytes

Sarah L. Perry、Yue Li、Dimitrios Priftis 等 5 位作者2014-06-16Polymers

Complex coacervation is an electrostatically-driven phase separation phenomenon that is utilized in a wide range of everyday applications and is of great interest for the creation of self-assembled materials. Here, we utilized turbidity to characterize the effect of salt type on coacervate formation using two vinyl po…

Tailoring the Electronic Structure in Bilayer Molybdenum Disulfide via Interlayer Twist

Arend M. van der Zande、Jens Kunstmann、Alexey Chernikov 等 15 位作者2014-06-16Nano Letters

Molybdenum disulfide bilayers with well-defined interlayer twist angle were constructed by stacking single-crystal monolayers. Varying interlayer twist angle results in strong tuning of the indirect optical transition energy and second-harmonic generation and weak tuning of direct optical transition energies and Raman…

Characterization of Titanium Dioxide Nanoparticles in Food Products: Analytical Methods To Define Nanoparticles

Ruud Peters、Greet van Bemmel、Zahira Herrera-Rivera 等 10 位作者2014-06-16Journal of Agricultural and Food Chemistry

Titanium dioxide (TiO2) is a common food additive used to enhance the white color, brightness, and sometimes flavor of a variety of food products. In this study 7 food grade TiO2 materials (E171), 24 food products, and 3 personal care products were investigated for their TiO2 content and the number-based size distribu…

МОДЕЛЮВАННЯ РУЙНУВАННЯ ПІДПІРНИХ СТІН ПРИ ВЗАЄМОДІЇ З АГРЕСИВНИМИ ПІДЗЕМНИМИ ВОДАМИ

Biliaev, N. N.、Gunko, Ye. Yu.2014-06-15The Scientific Issues of Ternopil Volodymyr Hnatiuk National Pedagogical University Series pedagogy

Purpose. Ground waters flowing through the soil could leach different salts and gases. As a result these waters obtain the ability to destroy cement solutions (cause the corrosion of cement stone). Prediction of the construction destruction in this case is a problem of great interest. The goal of this paper is the dev…
