Evaluating the environmental risks of these manufactured materials is essential to assist relevant risk assessment and ensure safety of such bio-synthesised nanomaterials. 
Lethality assay data are available not only for seaweed-derived metallic NPs but also for organic and inorganic engineered nanomaterials [5].

The sample was identified as Padina tetrastromatica based on definitive taxonomic keys.

First, there was inadequate technical engineering review during look- ahead scheduling.
Efforts were put heavily on the planning of construction methods and physical construction resources, such as labor, material, and equipment loading, but technical engineering review of upcoming work received much less attention.

Such type of concrete can be engineered by utilizing alternative cementitious materials such as silica fume, fly ash and Ground Granulated Blast Furnace Slag (GGBFS).
The utilization of these materials not only enhances the durability of concrete, but also helps in curtailing emission of greenhouse gases such as CO2 to the environment.
The specifications suggested that pozzolanic materials and silica fume could be used to ensure durability together with epoxy coated steel bars.

Introduction Among various semiconducting materials, silicon carbide (SiC) possesses unique physical and electronic properties.
This approach has been used to evaluate the optical properties of Si bulk materials [30] as well as Si NCs [31-36].

The ideal bone replacement materials would be osteoconductive, allowing the host bone to rapidly and completely replace the native bone.
Bio-materials made of metals, like those based on titanium, have properties that are exactly identical to those of human bones.

Hence, it is one of the most required materials in various fields such as optical, magnetic, thermal, electronic, sensor, catalysis etc.
Results and discussion Phase formation and surface morphology of copper oxide nanostructures The physicochemical properties of crystalline materials depend on the parameters such as crystallite size, morphology, grain boundary etc.
In the case of nanocrystalline materials, the synthetic route and the experimental conditions decide the particle size and morphology.
Even though all the three starting materials are converted into nitrate before mixing with alginic acid, from the thermal analysis of the precursor (Fig. 5) it is clear that the condensed polymeric precursors differ chemically from each other due to the nature of the starting material.

Introduction For modelling a process chain to predict the final material properties, it is necessary to use microstructural physics based models, since microstructure is the state variable of materials properties.
It comprises a twofold integration, namely a horizontal connection of the processing steps and a vertical connection of the physical models of microstructure development to the engineering level.
For Aluminum sheet the crystallographic texture was identified as microstructural key issue governing the resulting sheet properties.
The simulation started with tandem hot rolling and took the transfer slab material as input.
Furthermore the Deutsche Forschungsgemeinschaft (DFG) is gratefully acknowledged for providing funding through the collaborative research center SFB370 (Integral Materials Modelling).

PDA films can be easily formed on the surfaces of organic and inorganic materials.
