I am looking for someone to create Chapter notes for a chemistry textbook (University entry level). Think of it like a cliff's notes version of the textbook. To be more specific, I need you to take key concepts from each chapter, including any diagrams, and have it presented in a form of a study/review guide. I've attached a single chapter of the textbook as sample. Looking for somebody who can finish quickly. Thanks

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.

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.
