Aberration correction lenses help improve resolution in transmission electron microscopy

Using electron scattering and diffraction, transmission electron microscopy is able to achieve resolution higher than that of optical microscopy. However, the effect of aberration due to refraction of electron beams also introduce uncertainty into the image and reduces resolution. Nevertheless, the advent of aberration correction lenses has helped improve the resolution of transmission electron microscopy … More Aberration correction lenses help improve resolution in transmission electron microscopy

Conformal outsole of New Balance Fresh Foam Zante v2

Outsole of running shoes typically do not flex in response to the feet landing on the ground. However, New Balance has designed conformal outsole that flexes in response to each stride landing on the ground. Specifically, New Balance Fresh Foam Zante v2’s outsole flexes in response to the feet landing on the ground, which delivers … More Conformal outsole of New Balance Fresh Foam Zante v2

Reusing the first stage of a commercial rocket: Economic cost of retrofitting a used rocket

Rockets for satellite launches remain the most important cost item of the launch process of any commercial satellite project, given the single use nature of the rocket. Thus, commercial space launch companies such as SpaceX and Blue Origin have endeavoured to develop reusable rocket systems for reducing the cost of commercial satellite launches, and helping … More Reusing the first stage of a commercial rocket: Economic cost of retrofitting a used rocket

Challenges of recycling lithium-ion batteries

With increasing use of lithium ion batteries for personal mobile devices and computers, there is a concomitant need to plan the end of life treatment of these batteries that contain precious metals as well as toxic and flammable substances. Specifically, while lithium ion is thought to be the most important element for recover in the … More Challenges of recycling lithium-ion batteries

How does the outsole design affect the performance of the midsole in shock absorption?

Focus on running shoes have always been on the midsole foam technology as well as the upper mesh design and colors. But, what is less well known is the strong influence of the outsole on the performance of the midsole foam in absorbing shock and stress. Specifically, the thread pattern of the outsole affects the … More How does the outsole design affect the performance of the midsole in shock absorption?

Strain gauges for measuring structural stability of buildings

Many buildings in earthquake prone regions of the world are vulnerable to structural damage resulting from slow creep of movement of earth. Thus, could it be possible that modern buildings incorporate strain gauges and pressure sensors for understanding the vibrations within the building due to wind effect, ground movement, or inherent oscillations of the building? … More Strain gauges for measuring structural stability of buildings
