Obtaining movies of molecular movement of proteins through serial femtosecond crystallography

Seeing is believing; thus, it would be much better if we could observe real-time molecular level movement of proteins during catalysis, where, for example, binding of a substrate to an active site leads to molecular cleavage and enzymatic action. But, this feat is not realized until recent advent of serial femtosecond crystallography (SFX).   In … More Obtaining movies of molecular movement of proteins through serial femtosecond crystallography

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

Aggressive frontal aerodynamic features on 2017 Formula One cars

Changes in technical regulations afford 2017 Formula 1 cars with a larger wheel base as well as a faster overall speed for enhancing overtaking opportunities, which has been a bugbear of the sport. However, current Formula 1 cars may be unbalanced in distribution of aerodynamic downforce between the front and rear of the car, given … More Aggressive frontal aerodynamic features on 2017 Formula One cars

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
