Synthesis, characterization and cytotoxicity of polyethylene glycol coupled zinc oxide–chemically converted graphene nanocomposite on human OAW42 ovarian cancer cells

28-Sep-2015 | Atanu Naskar, Susanta Bera, Rahul Bhattacharya, Sib Sankar Roy, Sunirmal Jana, Polymers for Advanced Technologies, 2015

Present work reports for the first time on successful synthesis of polyethylene glycol (PEG) coupled ZnO–chemically converted graphene (CCG) nanocomposites (ZGP) as well as pristine nano ZnO (ZO), ZnO–CCG (ZG) and ZnO–PEG (ZP) by adopting facile solvothermal method using zinc acetate dihydrate, ...


Ultrabroadband superoscillatory lens composed by plasmonic metasurfaces for subdiffraction light focusing

24-Sep-2015 | Dongliang Tang, Changtao Wang, Zeyu Zhao, Yanqin Wang, Mingbo Pu, Xiong Li, Ping Gao, Xiangang Luo, Laser & Photonics Reviews, 2015

Abstract Conventional optics is diffraction limited due to the cutoff of spatial frequency components, and evanescent waves allow subdiffraction optics at the cost of complex near‐field manipulation. Recently, optical superoscillatory phenomena were employed to realize superresolution lenses ...


Sensors, Vol. 15, Pages 23418-23430: A Simple, Low-Cost Platform for Real-Time Isothermal Nucleic Acid Amplification

16-Sep-2015 | Craw, Pascal ; Mackay, Ruth E.; Naveenathayalan, Angel ; Hudson, Chris ; Branavan, Manoharanehru ; Sadiq, S. Tariq; ..., Sensors, 2015

Advances in microfluidics and the introduction of isothermal nucleic acid amplification assays have resulted in a range of solutions for nucleic acid amplification tests suited for point of care and field use. However, miniaturisation of instrumentation for such assays has not seen such rapid ...


A review of cellphone microscopy for disease detection

16-Sep-2015 | R. DENDERE, N. MYBURG, T.S. DOUGLAS, Journal of Microscopy, 2015

Summary The expansion in global cellphone network coverage coupled with advances in cellphone imaging capabilities present an opportunity for the advancement of cellphone microscopy as a low‐cost alternative to conventional microscopy for disease detection in resource‐limited regions. The ...


Probing Local Electronic Transitions in Organic Semiconductors through Energy‐Loss Spectrum Imaging in the Transmission Electron Microscope

02-Sep-2015 | Changhe Guo, Frances I. Allen, Youngmin Lee, Thinh P. Le, Chengyu Song, Jim Ciston, Andrew M. Minor, Enrique D. Gomez, Advanced Functional Materials, 2015

Improving the performance of organic electronic devices depends on exploiting the complex nanostructures formed in the active layer. Current imaging methods based on transmission electron microscopy provide limited chemical sensitivity, and thus the application to materials with compositionally ...


Microscopic and nanoscopic observations of metallurgical structures around inclusions at interior crack initiation site for a bearing steel in very high‐cycle fatigue

07-Aug-2015 | T. Sakai, N. Oguma, A. Morikawa, Fatigue & Fracture of Engineering Materials & Structures, 2015

Abstract In some high‐strength steels, a fatigue crack tends to occur at the interior inclusion after a long‐term sequence of the cyclic loadings at low stress levels, although the crack takes place at the surface in the usual life region at high stress levels. Thus, we have the duplex S–N ...


Complete determination of plant tissues based only on auto‐fluorescence and the advanced image analysis – study of needles and stamens

23-Jul-2015 | Aleksandar G. Savić, Suzana Zivković, Katarina K. Jovanović, Ludovic Duponchel, Ivica Kopriva, Journal of Chemometrics, 2015

Proper determination of tissues is one of the challenging problems in modern medicine and histology. Currently, interpretation of the results mainly depends on the experience of a histologist, leading to high percentage of results misinterpretation. Bearing in mind potential application, we ...


HERMES: a soft X‐ray beamline dedicated to X‐ray microscopy

26-Jun-2015 | Rachid Belkhou, Stefan Stanescu, Sufal Swaraj, Adrien Besson, Milena Ledoux, Mahdi Hajlaoui, Didier Dalle, Journal of Synchrotron Radiation, 2015

The HERMES beamline (High Efficiency and Resolution beamline dedicated to X‐ray Microscopy and Electron Spectroscopy), built at Synchrotron SOLEIL (Saint‐Auban, France), is dedicated to soft X‐ray microscopy. The beamline combines two complementary microscopy methods: XPEEM (X‐ray Photo Emitted ...


A Roadmap to Success in Photopharmacology

23-Jun-2015 | Johannes Broichhagen; James Allen Frank; Dirk Trauner, Accounts of Chemical Research, 2015

ConspectusLight is a fascinating phenomenon that ties together physics, chemistry, and biology. It is unmatched in its ability to confer information with temporal and spatial precision and has been used to map objects on the scale of tens of nanometers (10–8 m) to light years (1016 m). This ...


Efficient cross‐section preparation method for high‐resolution imaging of hard polymer composites with a scanning electron microscope

22-Jun-2015 | N. BRODUSCH, M. YOURDKHANI, P. HUBERT, R. GAUVIN, Journal of Microscopy, 2015

Summary Characterization of distribution and arrangement of filler particles in polymer composites is of primary importance to understand and maximize their mechanical, electrical and thermal properties. An innovative procedure that allows reliable and straightforward preparation of ...
