Monitoring of microbial cell viability using nanostructured electrodes modified with Graphene/Alumina nanocomposite   Original Research Article Biosensors and Bioelectronics, Available online 26 January 2017, Pages Rabeay Y.A. Hassan, Moataz M. Mekawy, Pankaj Ramnani, Ashok Mulchandani An ion-migration and electron-transfer cycle containing graphene and copper substrate analyzed with Raman spectra   Original Research Article Carbon, Available online 26 January 2017, Pages Weiyi Lin, Pingping Zhuang, Bo Tian, Tie Liu, Cankun Zhang, Tien-mo Shih, Weiwei Cai Graphical abstract Electrons transfer between graphene and electrically-contacted metals because of the former's semi-metallic characteristics. We discover a cycle comprising two components (graphene and copper) and two processes (ion migration and electron transfer). In this cycle, electrons travel from the copper to graphene based on Fermi-level variations, and ions migrate reversely via the intercalated electrolyte. To validate this proposed cycle, we investigate first the copper-oxide formation, then graphene-lattice phonon-frequency variations, and finally the morphological evolution of copper oxides via Raman and SEM measurements. Our study offers a guide for basic research on graphene-metal assemblies and broadens graphene-based applications.Image 1 A D-π-A organic dye - reduced graphene oxide covalent dyad as a new concept photosensitizer for light harvesting applications   Original Research Article Carbon, Available online 26 January 2017, Pages Teresa Gatti, Norberto Manfredi, Chiara Boldrini, Francesco Lamberti, Alessandro Abbotto, Enzo Menna Graphical abstract Image 1 Heavily aluminated graphene nanoplatelets as an efficient flame-retardant   Original Research Article Carbon, Available online 26 January 2017, Pages In-Yup Jeon, Sun-Hee Shin, Hyun-Jung Choi, Soo-Young Yu, Sun-Min Jung, Jong-Beom Baek Graphical abstract Heavily aluminated graphene nanoplatelets (AlGnPs) are produced by mechanochemical ball-milling of graphite with solid aluminum beads. AlGnPs show outstanding flame retardancy via chemical and physical flame retardation mechanisms. Hence, AlGnPs provide a very promising option for cost-effective, eco-friendly, efficient flame retardants.Image 1 Formation of dicalcium phosphate dehydrate coating on carbon fibers with in-situ grown graphene nanosheet interlayer   Original Research Article Ceramics International, Available online 26 January 2017, Pages Zhang Leilei, Li Wei, Li Hejun, Liu Shoujie, Li Shaoxian, Zhang Yulei Graphene nanosheets as counter electrode with phenoxazine dye for efficient dye sensitized solar cell   Original Research Article Organic Electronics, Available online 26 January 2017, Pages Iftikhar Ali Sahito, Kyung Chul Sun, Woosung Lee, Jae Pil Kim, Sung Hoon Jeong Graphical abstract Image 1 Access all 6 new results in ScienceDirect for : TITLE(graphene) and TITLE-ABSTR-KEY(graphene)
