Graphene Brouhaha: Why So Much Noise?

Graphene is a two-dimensional allotropic form of carbon, in which hexagonal crystal lattice atoms are combined, forming a layer of one atom thickness. Graphene was discovered in 2004 by Andrew Geim and Konstantin Novoselov, immigrated to the Netherlands and the UK, respectively.

Outstanding strength, flexibility and conductivity

The unusual properties of graphene promise a bright future for a good number of industries. Graphene boasts incredibly high strength. A one square meter sheet of graphene (again, keep in mind only one atom thickness) is capable of holding the weight of 4 pounds with no damage or even deformation. Due to the two-dimensional structure, graphene is a very flexible material that should enable its use in future, for example, for weaving yarns (the thin graphene material would be comparable to thick and heavy steel ropes). Furthermore, in certain circumstances, graphene is even capable of healing the deformations in its crystalline structure.

Graphene is a material with a sky-high conductivity of electricity and heat, which should make it the best choice for use in various electronic devices, especially, taking into account its flexibility and optical transparency. A number of experiments have been conducted on solar batteries made from grephene as a substitute to a relatively expensive indium selenide. Thus graphene solar cells demonstrate higher efficiency.

Another possible application of graphene is creation of flexible electronics, and in particular, flexible displays. In contemporary screens (LCD or OLED) indium tin oxide is used as a transparent conductor, which is relatively expensive and fragile. In this sense, high strength and flexibility of graphene make it an ideal candidate for a substitution. A widespread graphene use may certainly give a mind-blowing boost to the wearable electronics, as it allows embedding chips in clothing, paper and other goods of daily use.

Some graphene companies, e.g. 2-DTECH already assist businesses with integrating innovative solutions that imply using the neoteric material. According to 2-DTECH, the number of graphene uses even today is countless, the company is convinced the material will revolutionise the world in the nearest two decades. (more…)

Water Borehole Drilling In A Nutshell

Water borehole drilling job is typically implemented in case commercial or residential facilities are located at long range from central water supply infrastructure and there is no possibility for connecting an additional water supply system. As for residential purposes, homeowners are oftentimes not satisfied with the quality of the water, and this is where borehole drilling companies step in to conduct their business. Depending on the particular characteristics of the area, such businesses offer establishing a new source of water in the desired location for the customer.

Borehole drilling preparation submissions

Despite the widely spread myth, the adjustment of water supply does not depend much on geographical location. Therefore, a modern well can be built in virtually any region; the only difficulty consists in the depth of the inland waters. Before starting work, a group of specialists proficient in geophysics carries out a geological exploration in order to detect aquifers and determine the depth of their location. In addition, the driveway to deliver and accommodate the equipment is needed to be properly prepared. Since the equipment drilling is characterized by huge dimensions, it will simply not be able to travel to the place of proposed drilling, if the driveway appears to be smaller in size. It is also recommended to organize the 50 yards site approximately.

Post drilling complex of measures

Once the exploration and implementation of drilling water well is carried out, a chemical analysis of water is needed to be carried out. If the water has been extracted from the upper layers, it is suitable only for industrial purposes; drink such water must be avoided by any means. The fact should be underlined that the chemical composition of the water partially depends on the quality of work done. Thus, if the drill team works diligently and professionally, they will do their best to prevent water source pollution. Obviously, a greater percentage of successful completion of drilling depends on the particular company and its staff, so should definitely make an informed choice on the borehole drilling company.
