Filamentous bacteria transport electrons over centimetre distances
Oxygen consumption in marine sediments is often coupled to the oxidation of sulphide generated by degradation of organic matter in deeper, oxygen-free layers. Geochemical observations have shown thatExpand

Self-assembly of a nanoscale DNA box with a controllable lid
The unique structural motifs and self-recognition properties of DNA can be exploited to generate self-assembling DNA nanostructures of specific shapes using a ‘bottom-up’ approach. Several assemblyExpand

The influence of polymeric properties on chitosan/siRNA nanoparticle formulation and gene silencing.
We have previously introduced the use of the biomaterial chitosan to form chitosan/siRNA nanoparticles for gene silencing protocols. This present study shows that the physicochemical propertiesExpand

In Vivo Toxicity of Silver Nanoparticles and Silver Ions in Zebrafish (Danio rerio)
The influence of water chemistry on characterised polyvinyl pyrrolidone- (PVP-) coated silver nanoparticles (81 nm) was investigated. NaCl solution series of 100–800 mg L−1 lead to initial andExpand

One-dimensional metallic edge states in MoS2.
By the use of density functional calculations it is shown that the edges of a two-dimensional slab of insulating MoS2 exhibit several metallic states. These edge states can be viewed asExpand

Antifouling enzymes and the biochemistry of marine settlement.
Antifouling coatings are used extensively on marine vessels and constructions, but unfortunately they are found to pose a threat to the marine environment, notably due to content of metal-basedExpand
