VIP: Non-Invasive Probing of Nanoparticle Electrostatics
Dr. Kristina Tschulik, Dr. Wei Cheng, Dr. Christopher Batchelor-McAuley, Stuart Murphy, Dr. Dario Omanović and Prof. Dr. Richard G. Compton
Not what you might think: A new and non-invasive technique to probe the electrostatic interaction between surface-charged nanoparticles and a charged metal/solution interface shows that electrostatic effects are insignificant in all but very dilute electrolytes.

- Nanoparticle-Imprinted Polymers: Shell-Selective Recognition of Au Nanoparticles by Imprinting Using the Langmuir–Blodgett Method
Netta Bruchiel-Spanier and Prof. Daniel Mandler
Article first published online: 4 MAR 2015 | DOI: 10.1002/celc.201402407
Catch me if you can! The formation of a matrix that selectively recognizes nanoparticles based on their size, shape and shell is described. The essence of the nanoparticle-imprinted polymer (NIP) approach is to imprint the nanoparticles in a matrix followed by their removal. The matrix is made of cellulose acetate in which gold nanoparticles stabilized by dodecanethiol are embedded. Very high selectivity and recognition is demonstrated by this approach.

KISSA fast ECL: Although not purposely investigated to date, the relative diffusivities of the co-reactants in amine/transition-metal(II) electrochemiluminescence (ECL) systems strongly affect the ECL intensities, as demonstrated by simulations performed by using our homemade KISSA software.

The core of the matter: The core–shell structure of a LiFe0.5Mn0.3Co0.2PO4@C composite was synthesized by using a facile rheological phase method. The obtained nanoplatelets were decorated with a uniform and complete carbon coating layer (4 nm thick). Electrodes for lithium-ion batteries prepared from this composite exhibited excellent electrochemical performance, including good capacity and stable cycling behavior.

MOFs in the making: Much research is devoted to the synthesis of metal–organic frameworks (MOFs) for catalysis, separation, drug delivery and other applications. Electrochemical syntheses of MOFs have many advantages including mild conditions and shorter reaction times; however, the progress of these methods lags behind that of other methods. In this Review, research efforts in this area are summarized and critically assessed.
- Exceptional Activity of a Pt–Rh–Ni Ternary Nanostructured Catalyst for the Electrochemical Oxidation of Ethanol
Nina Erini, Stefan Rudi, Vera Beermann, Paul Krause, Prof. Ruizhi Yang, Prof. Yunhui Huang and Prof. Peter Strasser

A perfect match? Platinum, rhodium, and nickel are combined to create a novel electrocatalyst with activity towards ethanol oxidation in alkaline and acidic media, supporting the notion that surface NiOx is an excellent oxygenate-supplying catalyst component for the complete oxidation of ethanol (see picture).
