The design should have nothing similar with chemistry.

feedback plz

Well if u do not provide feedback then I'm not sure if get what you want soon...

The final logo should have a very clear design, without shadows or 3D effects.

Eliminating designs is a good start but not saying what you have in mind will not work. Please explain what you are looking for. What would you like to see in the design. If you have any examples of logos that appeal to you and might work for your business. Any input from your side helps. It's more than a month since you started the project - time cost money but you need to invest to get what you need.
Hope you'll get more involved into this...
Best Regards,
