Thank you sir for you reply!
I'm sorry but I have another question...
The process that creating a network via hydrogen bonds means not just interaction between alginate and alginate, but also interaction between alginate and water molecule??
I'm sorry.. Because I'm not the chemistry major...
Hello everyone.
I have a question about the sodium alginate (NaC6H7O6)n.
Recently, sodium alginate is widely used for fabricating edible bottle.
And I also try to utilize sodium alginate for controlling the viscosity of water.
I found that with small amount of sodium alginate powder in DI water...
Hi. I have a question about the term, "Ionic liquid"
When I researched the papers, I found the word "Ionic liquid" in many papers.
First, I thought the ionic liquid just means the solution that solvent is ionized.
But as I read other papers, I found that people don't mean ionized solution as...
Hi everyone.
I'm doing research with sodium alginate (NaC6H7O6) and I really need your help.
Sodium alginate is a cell wall component of seaweed or brown algae.
During the research, I read some pages telling that we can get alginic acid by dissolve sodium alginate in water.
But what I think is...
Hi everyone.
I have a question with a DLC (Diamond-like-carbon) coating.
In many papers, the DLC coating without hydrogen (a-C or ta-C) shows very good frictional properties and wear resistance with water lubrication.
I'm studying on eco-friendly engineering, so I surprised that water can be...
Hi everyone.
I'm a college student, and I need help of experts with gears.
What I know is that there are two dynamics in gear : rolling and sliding.
And I heard that the main cause of failure (wear) of spur gear is rolling.
Then... how about the cause of failure in the case of helical gear...
Hi everyone.
I'm designing a steady state feedback H2 control system.
Actually, my major is tribology and I have no experience in designing control system.
So it is really big problem for me.
Anyway, this is my simple model of tribometer which applies normal load on the surface.
(is it...
