ChemPlusChem 8/2015: Singapore Golden Jubilee Issue
To mark the 50th anniversary of the founding of Singapore, the Singapore National Institute of Chemistry is hosting an international conference in August 2015. This issue of ChemPlusChem highlights contributions associated with this conference and by authors based in this city--state.
The range of chemistry and chemistry-related topics covered in this issue is quite remarkable: from the synthesis of metal--organic frameworks (cover profile) described by Wen-Hua Zhang, the improvement of microbial fuel cells detailed in a minireview by Wei Huang, the synthesis of high-nuclearity nickel complexes reported by Pierre Braustein, and the study of RNA folding dynamics probed by Gang Chen.
Join the celebration!
This special issue is free to view in August.

It′s what′s inside that counts: The catalyst composition has been found to determine the reactivity and product selectivity of electrocatalytic nitrate-reduction reactions. The catalytic performance of both bimetallic (Pt–Pd) and trimetallic (Cu–Pt–Pd) assemblies was investigated. Reduction of NO3− to NH3 proceeded through a hydrogenation reaction followed by electrochemical hydrogen generation on the Pt–Pd surface. Hydrogen reduced NO3− to NH3 catalyzed by Cu (see scheme).

Family ties: Dithiocarbamate (DTC) glycoconjugates were synthesized, characterized, and compared to the parent DTC. Their copper(II) and zinc(II) complexes were investigated by electrospray ionization mass spectrometry and UV/Vis spectroscopy. The in vitro cytotoxic and apoptotic activities of DTC derivatives were assessed in human cancer cell lines, also in the presence of metal ions (see scheme). Moreover, their superoxide dismutase-like activity was determined.

Squeeze in! Sodium-deficient nickel–manganese oxides exhibit a layered structure, which is flexible enough to acquire different layer stacking. Specific features of the P3-type structure for reversible and fast sodium and lithium intercalation are demonstrated; this property contributes to the design of low-cost electrodes for both sodium- and lithium-ion batteries (see figure).
- Thermodynamically Favorable Conversion of Hydrogen Sulfide into Valuable Products through Reaction with Sodium Naphthalenide

Waste not, want not: The chemical waste hydrogen sulfide (H2S) is notorious for its production in many industries, harming creatures, corroding equipment, poisoning catalysts, and requiring energy-intensive and cost-ineffective abatements. Now a thermodynamically favorable process can convert H2S into value-added energy materials.
