Plasma meets with Kapton surface

Dielectric barrier discharges are a type of AC plasmas aiming to limit current in time to prevent spark formation. The dielectric layer holds charges, instead of letting them flow as in conductive materials. The constant exposure to plasma species causes wear/deformation on the surface. Here I show an example of Kapton layer. 1 is where …

Seminar notes: Bubble Puzzles

Here is a summary of an interesting talk on bubbles! Prof. Lohse has given us an interesting talk ranging from shrimp to Lawrence of Arabia. The main topic was the bubble formation on fluids and solids. First, he started with a well-known example of bubbles in a glass of water. He examined the jet formation …

Balancing climate change with gender equality

Do we really care about both climate change and gender equality? If yes, please continue! If no, abort mission! World Resources Institute (WRI) has released comprehensive studies since 2016 showing that women’s access to decision-making process, low-carbon industry, infrastructure and transportation can boost energy efficiency, investments in renewable power, and reduction in carbon emissions. Here …

Seminar notes: Is Hydrodynamics Relevant to the Origin of Life?

We are attending at least 8 seminars for every semester. Here is a short summary of the most interesting one! This was an interesting talk mostly focused on the bubbles formed in ocean and relating those with the origin of life. The speaker mentioned the mechanical forces created by waves in ocean and pointed out …

Science policy is giving rise to open science or a new form of capitalism?

Here is a provocative paper recently published. I will add my thoughts when I’m done with reading.

Chemical bonds simulated with quantum computers!

“Quantum chemistry is the science of understanding the complicated bonds and reactions of molecules using quantum mechanics. The ‘moving parts’ of anything but the most-simple chemical processes are beyond the capacity of the biggest and fastest supercomputers. By modelling and understanding these processes using quantum computers, scientists expect to unlock lower-energy pathways for chemical reactions, …

Acceleration with stars

His idea is that an advanced civilization could build a sphere that emits waste radiation in a specific direction. This radiation would accelerate the sphere—and the star it contains—in the opposite direction.” I’m not sure about the process of building a sphere around ‘stars’, but the idea is very exciting. However, comparing the whole universe, …

Stabilizing fusion plasmas

Sawtooth swings—up-and-down ripples found in everything from stock prices on Wall Street to ocean waves—occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some …

Surface-bound hydrogen: diffusion > desorption

Wait! What? “The first step in hydrogen storage is chemisorption, wherein gaseous H2 collides with Pd and adsorbs (sticks) to the surface. Secondly, the chemisorbed H atoms diffuse into the sub-surface, several nanometers deep.” Why gold-palladium alloys are better than palladium for hydrogen storage
