We just need a list of biomarkers/blood constituents (from the list of parameters that are tested in a regular blood test) organized in the order of their optical characteristic. Meaning the ones that have the strongest optical response first (which I believe are the ones that have more aromatic bonds or more number of tryptophan, tyrosine and phenylalanine in their amino acid sequence). We would like this as fast as possible.

Condensation can occur on the interior surface of windshields, reducing driver visibility. The windshield temperature can be cooled below the dew point temperature of the interior air: if the interior warm moist air contacts the cold surface, the water vapor in the air will condense on the interior surface of the windshield. To solve this problem, warm air is directed over the interior surface of the windshield to keep the interior surface of the windshield above the dew point temperature of the interior air. As the design engineer for the A/C system, you need to determine the time it will take to ensure driver visibility. You model the transient behavior of the windshield using the finite difference method to solve this problem. The model developed is below

Looking to hire an engineer to help me create/ work out a specific chemical application that would preferably be a spray on, that will reduce the friction on metal (stainless steel) and carbon surfaces. Freelancer will work with me to create an application that will greatly reduce the friction coefficient of these materials for a specific application that will be discussed at the beginning of the project. Application does not have to be permanent, but it would be very useful for it to last at least a little while after friction is applied to the material surface. Think a spray on type of teflon.

Electrical and aesthetic design for personal Ketone Breathalyzer. Product focus is on a digital readout of acetone levels present in user breath. Key skills include Electronic Design, Product Design, and Chemical Engineering. This product needs to be able to detect Acetone levels accurately and display them in the millimolar amount present in the user's breath. Our design goals for this product are geared towards a final product that is as minimal as possible. No moving parts; just a detachable mouthpiece. Operation of product would be ideal with just one button for the user to interact with. Lastly this job posting is for a product that will be a high end product.
