3 D Interlayer Nanohybrids Composed of Sulfamic‐Acid‐Doped PEdot Grown on Expanded Graphite for High‐Performance Supercapacitors
Authors: Kan Kan , Wang Lei , Yu Peng , Zhou Wei , Wang Ruihong , Lin Yufei , Shi Keying , Fu Honggang 
Published: August 2015

AbstractSulfamic acid (SFA)‐doped poly(3,4‐ethylenedioxythiophene) (PEdot) grown on expanded graphite (EG) nanohybrids (S‐PEdot/EG) were synthesized by surfactant‐free in situ chemical oxidative polymerization. The 3D hierarchical structure S‐PEdot/EG with homogenous ridgelike surface morphology was achieved by intercalating 3,4‐ethylenedioxythiophene monomers between the interlayers of EG using a vacuum‐assisted method. The composition of the nanohybrids and the π–π interaction between the EG and PEdot molecules were characterized by using Raman spectroscopy, thermogravimetric analysis, and X‐ray photoelectron spectroscopy. The nanohybrid with an EG content of 10 % exhibited excellent capacitive performance with a high capacitance of 139.6 F g−1 at 1.0 A g−1 in 1 m LiClO4 electrolyte. In the two‐electrode symmetric supercapacitors, the device performed with a high energy density of 6.83 W h kg−1 at the power density of 146 W kg−1, and retained high stability during the charge–discharge process. The excellent performance can be attributed to the 3D hierarchical structure, the π–π interaction between EG and PEdot molecules, and the doped SFA as an immobilized counter‐ion. This cost‐effective and simple method used to fabricate 3D S‐PEdot/EG nanohybrids is promising for the generation of electrode materials for high‐performance supercapacitors.
Strain inhomogeneities in epitaxial BaFe2As2 thin films
Authors: Chekhonin Paul , Engelmann Jan , Langer Marco , Oertel Carl‐Georg , Holzapfel Bernhard , Skrotzki Werner 
Published: August 2015

Epitaxial BaFe2As2 thin films grown by pulsed laser deposition on spinel substrates with a thin iron buffer layer show strain‐induced superconductivity. Using high resolution electron backscatter diffraction in a scanning electron microscope very small orientation changes (≤ 0.2°) of the lattice and strain inhomogeneities on a length scale of few 100 nm or less were measured. Furthermore, partially strain relaxed areas were revealed. It was found, that the quality of the BaFe2As2 thin films crucially depends on the iron buffer layer.
Organic Charge Carriers for Perovskite Solar Cells
Authors: Völker Sebastian F. , Collavini Silvia , Delgado Juan Luis 
Published: August 2015

AbstractThe photovoltaic field is currently experiencing the “perovskite revolution”. These materials have been known for decades, but only recently have they been applied in solid‐state solar cells to obtain outstanding power conversion efficiencies. Given that the variety of perovskites used so far is limited, a lot of attention has been devoted to the development of suitable organic charge‐transport materials to improve device performance. In this article, we will focus on the most promising materials able to transport electrons or holes from a structural point of view. Thereby, we focus on organic materials owing to their ease of preparation and manipulation, and this is nicely combined with the potential tuning of their properties through chemical synthesis.
The Role of MicroRNAs in the Chemoresistance of Breast Cancer
Authors: Wang Jing , Yang Muyi , Li Yu , Han Bo 
Published: August 2015

ABSTRACT

Preclinical Research

Breast cancer is the most prevalent malignancy in women with more than 1.3 million new cases every year worldwide. Chemotherapy is a critical therapeutic strategy for breast cancer, while chemoresistance remains a major obstacle to treatment success. In the past two decades, significant progress has been achieved in understanding drug resistance in breast cancer, involving drug efflux, alterations in DNA repair pathways, suppression of apoptosis as well as epithelial‐mesenchymal transition, and cancer stem cells. However, more effective therapeutic targets and novel biomarkers are still urgently needed to improve the overall survival and refine the therapeutic strategy for breast cancer patients. MicroRNAs (miRNAs) play crucial roles in cellular processes, such as cell differentiation, proliferation, and apoptosis. The recent discovery of miRNAs in malignancy has provided new directions for research on mechanisms underlying response to chemotherapy. Furthermore, several studies have documented that selected miRNAs, such as miR‐200c and miR‐34a, may influence response to chemotherapy in several tumor types, including breast cancer. The use of miRNAs as therapeutic targets to overcome chemoresistance is currently under investigation. In this review, we summarize the roles of miRNAs in chemoresistance through multiple molecular mechanisms, and highlight the potential diagnostic and therapeutic applications of miRNAs in overcoming breast cancer chemoresistance.
