Magnetic nanowires as permanent magnet materials
, 2007 We present the fabrication of metallic magnetic nanowires using a low temperature chemical process. We show that pressed powders and magnetically oriented samples exhibit a very high coercivity (6.5 kOe at 140 K and 4.8 kOe at 300 K).

Delaminated areas beneath organic coating: A local electrochemical impedance approach [PDF]
, 2006 Local electrochemical impedance mapping was used to investigate delamination phenomena at the steel/epoxy-vinyl primer interface. The delamination occurred from an artificial defect(cutter scribing) and from ageing in a salt spray chamber.

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes
ChemistryEurope, EarlyView.A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

Exploiting the localized surface plasmon modes in gold triangular nanoparticles for sensing applications [PDF]
, 2012 In this study we investigate and exploit, for optical sensing, the surface plasmon excitation in gold triangular nanoparticles with high aspect ratios (i.e., the ratio of the edge length of the triangles with the height) prepared by nanosphere ...

Multi-objective optimisation of bio-based thermal insulation materials in building envelopes considering condensation risk [PDF]
, 2018 The reduction in energy demand for heating and cooling with insulation materials increases the material related environmental impact. Thus, implementing low embodied energy materials may equilibrate this trade-off.
