FDA regulates e‐cigarettes, but advocates say more action is needed to protect youth
Authors: Knopf Alison
Published: May 2016

Last month, the Food and Drug Administration (FDA) issued rules that regulate e‐cigarettes, as well as other tobacco‐related products such as cigars, hookahs, and pipes. The rule extends the FDA's tobacco authority and implements the Family Smoking Prevention and Tobacco Control Act of 2009. The main focus is on banning e‐cigarette use by youth under age 18; e‐cigarette use (“vaping”) has been increasing in young people even as there have been tremendous decreases in smoking in that age group.
Stabilizing Low‐Silica Zeolites through Aluminum Sulfate Assisted Cannibalistic Dealumination
Authors: Shi Zongbo , Ji Peng , Zhu Zhiguo , Jiang Jin‐gang , Fu Wenhua , Wu Peng , Wang Yimeng , He Mingyuan
Published: May 2016

A versatile dealumination strategy was proposed to stabilize low‐silica zeolites through cannibalistic interaction between the host framework Al (FAL) and the guest aluminum salt. It is possible to capture selectively the FAL and Na ions in NaY zeolite by employing a special external Al source such as aluminum sulfate as the dealuminating agent. This unique postmodification reduces the FAL amount efficiently and converts the chemically reacted Al species into a γ‐alumina support for the catalytically active component of zeolite, which avoids wasting Al sources. Possessing greatly enhanced hydrothermal stability, newly generated intracrystal mesopores, as well as an optimized distribution of FAL, the resultant dealuminated Y zeolite catalysts can be used practically in heavy oil cracking.

Authors: Herrera‐Leyton Camilo , Madrid‐Rojas Matías , López Jhon J. , Cañete Álvaro , Hermosilla‐Ibáñez Patricio , Pérez Edwin G.
Published: May 2016

The mild and fast copper‐catalyzed radical and regioselective aminoalkoxylation of styrenes by using N‐fluorobenzenesulfonimide and simple alcohols as nitrogen and alkoxy sources, respectively, was investigated. The aminoalkoxylated products obtained could be used in the synthesis of new compounds with possible activity as neurotransmitter receptor ligands.
Pure Pyridinic Nitrogen‐Doped Single‐Layer Graphene Catalyzes Two‐Electron Transfer Process of Oxygen Reduction Reaction
Authors: Zheng Bo , Cai Xiao‐Li , Zhou Yue , Xia Xing‐Hua
Published: May 2016

A post‐treatment approach is presented to prepare nitrogen‐doped single‐layer graphene via ultraviolet/ozone (UV/O3) irradiation followed by NH3 annealing. Under optimal experimental conditions, a maximum atomic ratio (N/C) of 16.6 % can be reached. X‐ray photoelectron spectroscopy analysis reveals that only one type of pyridinic N is doped in the graphene lattice, which can be used as an ideal platform to investigate its catalytic activity toward oxygen reduction reaction (ORR). Electrochemical results demonstrate that ORR on the pyridinic N doped graphene sheet occurs via a two‐electron transfer process, indicating that the pure pyridinic N doped graphene is not an effective 4e‐process promoter.
Evaluating the Feasibility of Microbial Electrosynthesis Based on Gluconobacter oxydans
Authors: Gimkiewicz Carla , Hunger Steffi , Harnisch Falk
Published: May 2016

Primary microbial electrochemical technologies are utilizing the interfacing of microbial redox reactions and electrodes. Based on its exploitation as recognition element for bioelectrochemical glucose sensors and inspired by its biotechnological potential Gluconobacter oxydans was studied on its suitability for microbial electrosynthesis. It is demonstrated that in bioelectroreactors the conversion of glucose by G. oxydans based on mediated extracellular electron transfer is not related to electric current flow. Oxidation current can only be recorded after preceding aeration phase, but the response does strongly depend on the microbial activity status, pO2 and gas supply as well as the pH regime. It is proven that the electric current is derived from the microbial cells, but the mechanism still needs to be elucidated. The suitability of G. oxydans for microbial electrosynthesis but also for bioelectrochemical sensors is critically assessed.
