2 Guys in Chemical Engineering wanted to create Take-offs from P&IDS and analyze P&IDs using HYSYS and create equipment specs sheets. 2 Draftsmen needed to work on the existing P&IDs and convert them into the 3D model to get piping and materials list. Everyone is needed to work in parallel. Cost is not an issue, only problem is only time. All is required to be done by 3rd Feb. Please apply if you can do it before that time.

We're looking for someone with access to a vacuum hood and an alginate centrifugal mixer (50ml) or another equivalent mixer to measure and mix together batches of nanoparticles and polymers. This would be a semi regular job and we would ship you the chemicals to mix and send to us in NYC.

Data collection research project involving ionic migration/conductivity electroceramic electrolytes as used in solid oxide fuel cells (SOFC). Some of these papers derive from the industry involved, but the majority will likely come from academic studies. This project does NOT require researcher to characterize materials or conduct experimentation. This project is for collection of, and rapid means to navigate the appropriate papers. It does NOT require an analytical report. Researcher will provide appropriate papers, and reference the materials’ characteristics as specified below via matrices/spreadsheet. Please pay special attention to alumina and materials that exhibit similar coefficients of expansion, as well as perovskites. It involves compilation of a comprehensive (though perhaps not exhaustive) collection of published, peer-reviewed articles, and organization of the contained information in a spreadsheet (MS Excel preferred, but any compatible program acceptable) utilizing the following criteria for characteristics’ criteria: 1. Membrane material – electrolyte only (e.g. yttria stabilized zirconium, alumina, aluminum titrate, etc.) 2. Thickness of membrane film (in µm or nanometers.) We are principally interested in sub-micron scale. 3. Membrane surface area. 4. Sealants used. 5. Temperatures 6. Velocity of ionic migration through electrolyte membrane (Siemens per cm). 7. Velocity comparison (by order of magnitude) of stressed membrane to unstressed, bulk material (where available.) 8. Electrode materials used for both anode & cathode (e.g. Pt, Ru, Ni, Co, doped ceramics, etc.) 9. Working fluid (e.g. O, H, He, Ar, etc.) 10. Internal stress during operation (expansion) 11. Means of obtaining stress (where applicable.) e.g., differences in coefficient of expansion, piezoelectric tensions applied, etc. 12. Fabrication method used. Most, but not all, of these will involve ceramic casting of various sorts. Such studies have been conducted for over ten years, and probably number ~50+, but could number several hundred. Ignore duplicate data. Researcher will present the articles themselves (PDF format please), and the above bullet-listed matrix criteria should reference to the articles (comment tags in Excel cells). Researcher should have access to deep knowledge base in chemical engineering/materials science or related field.

I am looking to hire a chemist/scientist or anyone who specializes in thermodynamics to create & develop a paper-like substance that will react with a liquid and become cold (4-6 degrees C.) for a short period of time. (1 hour). It will be a one time use disposable product. Some have suggested ammonium chloride. MUST be non-toxic and the liquid that is cooled from this product must be safely consumable.

I'm looking for creative and innovative team to prepare a complete technical, design and blueprint document for a next generation mechanics for commercialization. To be part of the team, individual needs to have experiences in the following subjects: - Computer science (Artificial Intelligence, Computational linguistics) - Engineering (Acoustical, Automotive, Chemical, Control, Electrical, Electronics, Mechanical, Mechatronics, Microelectronics, Nano, Optical, Software) - Psychology (Cognitive, Behavioral) - Physics (Dynamics, Kinematics) The project will be divided to several teams for different components, and should be familiar with terms such as: - Muscle group (Creating 850 muscles equivalent to a human body; 42 facial muscles equivalent to a human face) - Artificial / Synthetic, Sensors Skin (measure, stretches, senses, feel); Associated humidity sensores, eletroresistive heater and stretchable multi-electrode arrays, strain, pressure and temperature sensores - Exoskeletons - Hybrid fuel cells (Rechargeable Hydrogen Fuel Cell, Polymer Exchange Membrane Fuel Cells) Additional consideration on the safefy, lifetime cycle, weight, heat dissipation, form factor and cost Flexible arm & hand movements (At least 24 joints with 20 degrees of movement freedom for hand construction) - Zero Movement Point (ZMP), Dynamic-balancing and Passive-dynamics - Environmental interaction and navigation (extremely intuitive interface allow communication through speech, gesture and facial expression); Speech recognition; Synthetic voices; Facial expression; Social intelligence Information within the technical, design and blueprint document must be a working solution, and will be verify against subject matter expert from Stamford University, Bao Research Group, C3 Nano, MIT and etc. This project is not a fictional, or a built-and-sell project. I just need a complete documents, including technical requirement, specification, design consideration, final rendering, blueprint, hardware & software requirement, as well as other related information require to successfully construct the final product. Qualification questions is one method to gauge your experience and knowledge in this project. At the same time, feel free to ask me questions, just in case I missed out any. Good luck.

Hi, The below task needs to be done. Please look into the details. The work must be all ORIGINAL, and any form of copy-pasting will be rejected. Being well-versed in APA Referencing would be an added advantage for the applicant. Problem statement: Your task is to design a distillation column to separate 1000 kmol/h of a multicomponent mixture consisting of 8 mol% n-pentane, 42 mol% n-hexane, 38 mol% n-heptane and 12 mol% n-octane with 98% recovery of n-hexane in the distillate and 98% recovery of n-heptane in the bottoms. You should determine: i) optimum reflux ratio, ii) optimum feed plate, iii) total number of equilibrium stages, iv) total number of real stages, v) column height, vi) column diameter, vii) estimate of the column cost You should use the following design specifications: • Pressures: Pressure of column = 405.3 kPa Pressure of reboiler = 406 kPa Pressure in condenser = 404 kPa • Total condenser and partial reboiler • Sieve trays with 24-inch tray spacing • Feed flow rate is 1000 kmol/h of saturated liquid • Feed composition: 8 mol% C5H12, 42 mol% n-C6H14, 38 mol% n-C7H16, 12 mol% n-C8H18 • n-C6H14 recovery in distillate: 98% • n-C7H16 recovery in bottoms: 98% • Trays operate at 75% of flooding Project requirements: The project should be completed in teams of 3. You are expected to use process simulation tools such as HYSYS to assist you in completing a rigorous design of the distillation column. Also, you should conduct hand calculations using a shortcut method to check the simulation results and discuss any differences that you find. You should clearly explain your methodology and justify any assumptions you have made. The final report should contain the following sections: i) Cover page ii) Abstract iii) Table of contents iv) List of figures v) List of tables vi) Introduction vii) Problem statement viii) Hand calculations – methodology and results ix) Simulation results x) Results summary and discussion xi) Conclusion xii) Appendix xiii) References

We need a specialist to develop formulation (recipe) for a supplement product. We have the idea for the product type, how it should be consumed, what effect would it have to its consumers. But the exact formulation of the ingredients is required. It is recommended for the freelancer to have previous experience with such or similar task. Budget is not final, can be discussed.
