How to choose a watch?

Citizen for men
Citizen for women

The watch has necessity and it become in a beautiful thing and suitable for any gender and any age.How to choose the right item of jewelry and which item will make us unique and different?
So we should follow some of techniques that help us to find and choose  the right things. There are some rules are follow such as
1. According to the mechanism of the clock
The clocks are available in three types such as mechanical, electronic and electro-mechanical. There are three arrows in mechanical clock such as hours, minutes and seconds andon the screen the quartz displays the current time in numbers.The new models display the exact date , except time and air temperature.It is looking better externally and controversial.
2.According to the material
First we have to need a watch is the material and it is the important factors. It is made different types of materials such as gold, silver, brass, platinum, plastic, stainless steel, aluminum alloy, lead , titanium etc. Stainless steel and brass are mostly used. These are extremely durable and affordable in price.When anyone want to use platinum or gold then should careful because they are easily scratched. There are various  types of glass use for watch such as sapphire, minerals, plastic, crystal etc.Plastic materials are really inexpensive.  So you can hold other option for choose it.

3. According to the style
Giordano for women
There are various types of watches available in the market and they have different style, colors, shapes and materials. You should choose watch according to your own preferences and style.Watch with rubber strap is the
ideal choice for an athlete , active and love hiking  person and it is ideal for causal environment.For classic look leather or metal strap is best and it will look more clean, elegant,so you should the strap that will ideally fit your hand.
4.Price and maintenance
The price of the watch determines large part and when anyone choose a beautiful , sustainable watch then need invest more money . The watches  will be returned many times over the years and that will not regret for you. You can choose and inquire the manufacturer. You can experiment with materials, brands and colors freely and you can search the real one.You can collect and buy this product and should take care of it

Electric charge propagating along microbial nanowires

Electric charges indeed propagate and along with microbial nanowires that produce nanotubes . It is a highly conductive human-made material. Microbiologist Derek Lovely and colleagues of the University of Massachusetts Amherst researched that microbe Geobacter produces tiny electrical wires that is called microbial nanowires. Malvankar says that they injected electrons at one spot in the microbial nanowires  and through the nanowire  the electrons  propagated  and whole filament lit up. In biology it offers many opportunities and in biological proteins EFM has been applied. Lovely says that through microbial nanowires , the ability of electric current to flow and has practical implications and environmental .Through these wires, Microbial  species electrically communicate and methane gas produce by conversion of wastes and sharing energy.
Geobactor act an important role in environmental cleanup and significantly changing soil chemistry . This geobactor live in on iron and other metals in the soil. Geobactor has ability to produce electricity and it is adapted to biological computing devices and adapted to engineer microbial sensors. It has protein filaments and metallic- like conductivity. It can conduct electrons like a wire. It has biochemical stepping-stones and it can hold the individual electrons. It has metallic-like conductivity and these are conducted to a copper like wire. Malvankar and Tuominen’s labs in 2011 says that   Metalic-like how to changed with different temperature or PH. In their hypothesis, add more support and it is removing the aromatic amino acids that is necessary for metallic-like conductivity. It has delocalized electrons and has final key evidence.
It has microbial nanowires and it is protein. It has ability to visualize the charge propagation and in the nanowires  at a molecular level. This technique has speciallity about physics and biological interest. In Tuominen ,this is important in biology and in materials science and this discovery is not only an important nw principle. Natural amino acids can produce carbon nanotubes and it has exciting opportunities for protein-based nanoelectronics. It has potential   green electronics and it is made from non-toxic materials , renewable. For a diversity of applications , it can be engineering electric microbes , genetically manipulated . To detect environmental contaminants , Geobactor making into electronic sensors.There  are also Geobacter-based microbiological computers. The office of naval research, the national Science Foundation and the Department of Energy was supported this.
