 In spite of worldwide research, carbon nanotubes (CNTs) still have not fully realized their

 original promise as ideal reinforcements for composite materials due to a number of

 challenging issues such as weak interface, poor dispersion, misalignment and lack of optimized

 design. Here we propose a bio-inspired structure of CNT bundles with controllable

 crosslink density and staggered pattern of organization that mimic the architecture of

 Biological materials in nature serve as a valuable source of inspiration for developing

 novel synthetic materials with extraordinary properties or functions. Much effort to date

 has been directed toward fabricating and understanding bio-inspired nanocomposites

 with internal architectures mimicking those of nacre and collagen fibril. Here we establish

 simple and explicit analytical solutions for both upper and lower bounds of the elastic

I apply force using one slider to another slider. Best part is one slider move little bit and help second slider to slide 6 times length at 70 % force.

Energy Used to move first slider=force*distance

=100N*0.05m

=5Nm

Energy Get on Other Slider= Force*Distance

=Force applied by first slider*cos(45`)*distance

=100*0.7*0.25

=17.5

We get 3 times energy on second slider than we use to move first slider.

A lot work has been done/published in the area of in-situ mechanical testing using electron microscopy. Please list which, according to what you feel has had a significant impact. Here are two in my opinion:
