The production stage refers to the smelting process, cobalt become crude products from raw materials, raw materials including domestic cobalt resources, imported cobalt resources and secondary cobalt resources.
It indicates that battery is the major consumption of cobalt, cobalt application in the field of battery materials mainly in lithium cobalt oxides, ternary cathode materials, hydrogen storing alloy and spherical nickel.
In the stage of production, 5100t cobalt raw materials has consumed in 2012.
These are the raw materials of Li-ion battery, magnetic materials, cemented carbide tools, ceramic, and catalyst.

A study was carried to develop model equations for selecting optimum storage parameters for stored cabbages in passive evaporative cooling structures.Three sets of four different types of passive evaporative cooling structures made of two different materials; clay and aluminium were designed and constructed as part of the study.
Materials and Methods Mature cabbages were obtained from Minna Central Market in Niger State and transported in wooden crates to the laboratory.

Introduction Unmodified thermoset epoxy resins usually have poor impact resistance and fracture toughness, which limits their applications as structural materials.
It is well known that addition of rubber to brittle epoxies can greatly improve resistance of the materials to crack propagation (1-4).
Pre-cracks were produced by the razor blade pressing method because, in current materials, it can create a sharp pre-crack which quickly jumps several millimetres ahead of the razor blade front when the razor blade edge penetrates a few millimetres into the specimen.

The road safety barrel commonly employs the polypropylene (PP) material[1,2,3].The material is light-weighted, corrosion-resistant, of good cushion-effect and easy to process, making it widely used in vehicles and roads.
Bilinear kinematic material model (BKIN) is used for Road safety barrel [4], and rigid body models are used for vehicle body and displacement constraint.

From the materials point of view, PAAM is an electroactive hydrogel that can sense the biological environment and respond to external stimuli in a controllable way [3-4].
Materials and Methods Acrylamide 97%, N,N'-methylenebisacrylamide ≥ 98%, N,N,N',N'-tertramethylethylenediamine 99% (TEMED) and ammonium persulfate ≥ 98% (APS), was used.
Water was repeatedly changed to wash out most of the extractable materials and allow them to reach an equilibrium.
