dat head fit still carry book??

all i see there is somtin dat looks like light reflection

op the last one na iroko spirit joh

hdd 25gb ?? how many yrs i won download am finish ?? wit this edge wey dey my area ?

#3 rilli got me tinking ?? is dat programming error predicting d future abi wetin ?? som rilli need to explain dis

kowalsky: the lamboghini sexto elemento costs more than all the afforementioned car

sexto elemento comes with $2.9m price tag nd 570hp.

wetin dat man on left carry for head ?

useles idiots. i hope dey unite wit dere virgins in hell

iro oo. pple no gree giv am money for street na so he turn to his accnt

where is d phone spec nw ?

pics and phone spec.

y not if i av d money

(In iya ibadan's voice) op is a foolis sombody

And he'll still win the election

fabregas !!!!!!!!

It seems phone batteries always die at the same moment you need to make an important call. But while shouting at your mobile in frustration might seem pointless, a new gadget could soon mean your screams won't be in vain. Researchers in London have created a new technology that uses sound, such as chants at a football ground or chatter in a coffee shop, to charge up mobile phones.
While shouting at your mobile in frustration might seem pointless, a new gadget could soon mean your screams won't be in vain. Researchers in London have created a new technology that uses sound, such as chants at a football ground or chatter in a coffee shop, to charge up mobile phones
Their prototype device, which is about the size of a mobile phone, uses zinc oxide to convert vibrations caused by sound into electricity. The invention was inspired by previous research at Queen Mary University of London ( QMUL), which found playing pop and rock music improved the performance of solar cells.
This was because the sound vibrations triggered the movement of material in the solar cell that caused it to improve efficiency by up to 40 per cent. Developing this research further, Nokia worked with the QMUL team to create an energy-harvesting prototype that could be used to charge a mobile phone using everyday background noise.
Nokia worked with the QMUL team to create an energy-harvesting prototype that could be used to charge a mobile phone using everyday background noise. Pictured here is the zinc oxide used in the device
The team used the key properties of zinc oxide, a material that when squashed or stretched creates a voltage by converting energy from motion into electrical energy, in the form of nanorods. The nanorods can be coated onto various surfaces in different locations making the energy harvesting versatile. When this surface is squashed or stretched, the nanorods then generate a high voltage.
The nanorods respond to vibration and movement created by everyday sound, such as our voices. Electrical contacts on both sides of the rods are then used to harvest the voltage to charge a phone. In order to make it possible to produce these nanogenerators at scale, the scientists found innovative ways to cut costs in the production process. Firstly, they developed a process whereby they could spray on the nanorod chemicals - almost like nanorod graffiti - to cover a plastic sheet in a layer of zinc oxide. When put into a mixture of chemicals and heated to just 90°C, the nanorods grew all over the surface of the sheet. Secondly, gold is traditionally used as an electrical contact, but the team were able to produce a method of using cheap and cheerful aluminium foil instead. The final device is the same size as a Nokia Lumia 925 and generates five volts, which is enough to charge a phone. 'Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept,' said Dr Joe Briscoe from QMUL. 'We hope that we have brought this technology closer to viability.'

Nw dats i'm talking abt !!! Goal !!!

Debuchy get ebola ??

0:1 3more togo

arsenal 0 4 city.. he go pepper dem

yet MTN dd nt give me 1gb of 13 anniversary. ..... in jst 5 month? dey ar makin enough to reduce dere call rate to 10k/sec or less nw

she must av done somtin wrong, i no dey support bad tin jare

cortana programmers ar really crazy sha !!!... wo eva or group dat develop dat tin ar fucking genius !!!

d devil is a lier. cortana must fail tonyt #holland
