Early one morning in 2019, I went to the Overlook Park to do exercise as usual. I saw two letters "T.K." written on the pathway entrance (left image at the bottom) and the floor (right image at the bottom) of the park pavilion. I pondered them in my heart because they are the initials of my former name Tangcheng Kuang. At that time, I was thinking of the meaning and direction of my research. I prayed to God for a theme to build a website. I thought He might have given me the theme: Thermodynamics and Kinetics. One year later, I thought that the term "Key Technologies" might better fit my website theme.

I designed the logo using the two letters. The alpha-helix and beta sheet are taken from the atomic-level model of SARS-CoV-2 spike glycoprotein. The whole shape looks like a transistor representing key technologies. The V-shape means victory.

In a word, I want to tell you that the website domain name, the logo and the theme are inspired by the two letters "T.K.". Their photos have been taken and shown here.
