Defect structures in CuZr martensite are studied by conventional and high-resolution transmission electron microscopy. Two different types of planar defects are observed. It is concluded that both defect types can be inherited from anti-phase boundaries in the austenite phase. With respect to the martensitic transformation, both defect types can be explained by the different shuffles of atoms a...

In the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. In this work, α-Fe2O3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (FeCl3.6H2O) as precursor and ammonia solution as precipitator. The samples we...

Hydrogels are introduced to modem medicine as novel materials suitable for a variety ofbiomedical applications. Studying hydrogels as novel biomaterials has become a fast-developingand exciting research field during the last two decades. These interesting biomaterials have found awide range of application including contact lenses, vehicles for drug delivery and scaffold in tissueengineering and...

Strategically, ‘biomaterials research’ should be refocusing its science on new areas – but it has not! Traditionally, biomaterials research has been heavily leveraged in ‘synthetic biomaterials product-testing’, but it should be moving towards ‘biological materials and clinical research’. There is an adage (Lubin’s Rule) that says ‘If another scientist thought your research was more important t...

fuel cells, secondary batteries and capacitors are among many promising energy storage devices. in particular, supercapacitors have attracted much attention because of their long life cycle and high power density. graphene/nickel ferrite(g-nf) based supercapacitors were successfully fabricated through a one-step facile solvothermal route. effects of synthesis conditions i.e. solvothermal time a...

The characterization of nanostructures down to the atomic scale is essential to understand some physical properties. Such a characterization is possible today using direct imaging methods such as aberration-corrected high-resolution transmission electron microscopy (HRTEM), when iteratively backed by advanced modeling produced by theoretical structure calculations and image calculations. Aberra...
