Tomorrow’s Chemistry Today: Concepts in Nanoscience, Organic Materials and Environmental Chemistry

Carbon Materials And Technological Advances

Carbon, one of the most abundant element in nature, has the capability to be combined chemically with itself and with other elements by strong covalent bonds resulting in a variety of structures that enable the development of resources of Different properties. The carbon materials can be very solid as diamond or graphite as easily delaminated, very dense, high strength (composite materials carbon / carbon), and therefore appropriate for structural applications (aircraft and racing cars), or very porous (activated carbon); the latter being useful as adsorbents for energy storage or as a support for catalysts. They can be Extremely conductive (graphite) or insulating (vitreous carbon). This broad spectrum of properties is reinforced by the fact that only carbon resources are capable of operating at extreme temperatures in the most extreme conditions.

The carbon materials have been gathered much attention with the discovery of fullerenes and nanotubes. However, traditional carbon supplies have played an principal role since prehistoric period (pigment in cave paintings, a component of gunpowder, writing) and have contributed to the manufacturing and technological development of our society (steel).

The discovery of carbon fibers in the ’60s, with its eminent strength and flexibility, was a major achievement in the development of these materials. In parallel, we discover the vitreous carbon, named after filing a conchoidal fracture surface, with properties analogous to glass, very solid and brittle. At the same time, the discovery of brand new structural forms of graphitic carbon, needle and spherules, ostensibly contributed to the development of new carbon Materials for very diverse applications.

The outstanding biocompatibility of carbon materials, revealed in the 70s, its service in prostheses, ligaments and heart valves, among others.

In the early ’80s, the development of machinery for producing blocks of high-level density isotropic graphite allowed its application in high temperature reactors, in devices of synthesis of semiconductor crystals and to components of electric discharge electrodes. At mid-80s,  the introduction of carbon fibers in civil engineering, architectural systems (buildings, bridges) with the discovery of fullerenes.

In the 90s, was discovered nanotubes, opening a modern era for carbon supplies: The era of the nanostructure. It is not just the world of carbon graphite flat structures or three-dimensional type diamond, but we are now with closed structures containing pentagons of carbon atoms and carbon tubes with diameters in the nanometer scale, made of a sheet plain curved carbon atoms in hexagonal distribution. The discovery of carbon nanotubes of a single wall (single) and multiple wall, stimulated the fascination of scientists and engineers in fields associated to nanotechnology. At the same time, new applications of the materials of the family of graphite, such as anode materials for Li-ion battery rechargeable carbon fiber water refining, activated carbon electrodes for electric double layer supercapacitors, etc. .

More recently, in 2004, was developed the isolating graphene, a flat sheet structure of an atom thick. Its exceptional electrical properties have revolutionized the field of science, finding application in electronics (ultra-fast computers, replacing the silicon), in the imminent construction of space elevators, individual protection systems (body armor) in the field of security etc.. In July 2008, researchers at Columbia University confirmed that this is the strongest material so far identified.

Research Analysis on Materials Which Improve the Performance of Military Clothing

Bharatbook.com included “Developments in military clothing, 2008 edition” report which provides aesthetic appeal of military clothing and its impact on soldier morale

Military clothing is an integral part of a soldier’s fighting kit. It plays a key role in protecting soldiers  during combat, and must therefore perform several functions in the most rugged of wearing conditions.  At the same time, it must remain durable.

Developments in military clothing have been driven mainly by changes in the ways in which wars are  fought. Because modern warfare is more likely to take place in congested urban streets than on  battlefields, today’s military clothing has an appearance and performance characteristics which  contrast sharply with those of uniforms worn by soldiers fighting in the trenches during the First  World War.

Since the terrorist attacks on the USA on September 11, 2001 (9/11), and the consequent war on  terror, the demand for military clothing, body armour and other military equipment has risen sharply.  In turn, this rise has greatly benefited a number of clothing manufacturers in the Western world.

The ever present threat of terrorism has raised concerns about the vulnerability of military forces in  general, and troops in war zones in particular. Governments around the world have sharpened their  focus on military preparedness—including how best to clothe and equip their countries’ soldiers. They  have invested heavily in the development of military uniforms which improve a soldier’s performance  and comfort and offer the potential to save lives during combat.

As a result, developments in military clothing are being made today at a faster pace than at any time  in history. New battledress concepts which harness nanotechnology and other advanced technologies  have been devised with a view to helping the performance of soldiers on the battlefield by improving  their ballistic protection, reducing the weight they carry, optimising their camouflage and amplifying  their physical strength.

For the future, scientists have designed concepts for highly advanced multi-functional combat wear.  However, it many take several years before these technological breakthroughs can be translated into  wearable products.
