Chemistry: A Truly Blue Sky

UPDATE  (May 14th, 2019) Recently, Professor Jang Wook Choi had informed me that Professor Cui wanted me to try another project with him in Stanford instead of the fine dust mask particle project that I have been working on. He has recommended me to work with experimenting and researching about flexible batteries that Professor Jang Wook Choi was recently acknowledged for, in his recent invention in making flexible portable charger that you can put on your wrist to charge your Apple Watch. However, this doesn't mean that this fine dust particle journey will end. Even though I will not continue this experiment at Stanford, I will try to experiment and discover more in Professor Choi's laboratory at Seoul National University. It will probably be seen that the battery project with Professor Cui will be continued and introduced newly through another blog, and if made, I will inform and provide a link for more people to see. Once again, this experiment process is not a failu

I have found this Korean channel on YouTube that I enjoy watching because he creates various science experiments and pranks that relate to using machinery or learning basic ideas of chemistry or physics.  Recently, he had uploaded a video that is very similar to the experiment we will do during the summer. I think it will be helpful for viewers to watch to get into depth for our experiment. *Note: The video is in Korean

UPDATE - May 1st, 2019 Good news! I have communicated with Professor Yi Cui about my project, and I guess he will be looking forward to seeing me and helping me with my experiments during the summer at Stanford University! *Quality of the email screenshots seem to be very blurry, so here is the email content: Dear Professor Cui, Greetings, my name is Justin Choi, and I am currently a high schooler in Seoul International School that is very beloved in math and science. Recently, I have been researching for weeks of the reasoning behind the bad air quality in Seoul, which is due to the existence of fine dust particles. To this day, I developed my knowledge of what exactly fine dust particles are, as well as the function behind the common facial yellow-dust K94 masks that Koreans wear every day. Until now, I have been collaborating with Professor Jang Wook Choi in finding the basics of the project and idea, and he recommended me to have a deep discussion with you

Outside View UPDATE - May 5th, 2019 I visited Professor's Jang Wook Choi's lab at Seoul National University (SNU) to take a small trip around to understand the environment of an actual university lab. Coincidently, there was the electrospinner machine in one of his labs, and it was significant because it was a preview of one of the main machines I will use for my future experiments.

UPDATE Good news, I have received a brand new clean air particle counter from a professor I knew. According to this professor, this machine will be very helpful for my future experiments because it can count the air particles in a certain area. Using the quantitative results this can give me, I can produce data and soon make a conclusion through this helpful source.

Woven vs. Nonwoven? An important factor of the materials research is to exactly know what type of resources were used to make the filtering system from the Korean-made yellow dust masks. In order to know more about this, I started to investigate the basic facts of what I think I should know about fabrics and textures used in clothes and filtering systems. The huge distinction between various clothes or filtering materials is to see if it is woven or nonwoven. Woven is the past-tense term of the verb 'weave', which is to basically demonstrate any texture or cloth formed by weaving. According to Wikipedia, "Woven fabrics are often created on a loom, and made of many threads woven on a warp and weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another."
