I need an experienced palm-oil technologist to help me raise the purity and improve the chemical profile of my crude palm oil by fine-tuning the existing refining line. My current production meets basic food-grade standards, but I want a cleaner product with lower FFA, peroxide, and trace metal levels so it competes with premium brands. The focus is strictly on refining process optimization—no changes to raw-material sourcing or additive blends at this stage. What I need from you • Audit of my present degumming, neutralization, bleaching, and deodorization steps (P&IDs, temperatures, residence times, vacuum levels, etc.) • Data-driven recommendations for parameter tweaks or equipment upgrades that can realistically be implemented on my line • Predicted ta...

I am seeking a qualified professional with demonstrated experience in both Engineering and Industrial Hygiene to develop a comprehensive, technically sound Industrial Hygiene (IH) proposal. The proposal must be written to a high professional standard and suitable for submission to corporate, regulatory, and/or government clients. The successful candidate must have strong knowledge of occupational exposure assessment, sampling methodologies (air, bulk, wipe, noise, etc.), ventilation evaluation, and regulatory compliance frameworks. Experience developing defensible IH sampling strategies, risk assessments, and technical scopes of work is essential. The final deliverable should reflect senior-level Industrial Hygiene competency (CIH-level quality), including clear objectives, methodology, Q...

I need a seasoned academic writer who can craft a 4,000–5,000-word manuscript on “Molecular Design of Silicone Adhesives with Thermal Resistance at 500 °C and Synergistic Acid-Thermal Aging Mechanism,” polished enough for submission to an EI-indexed journal. Scope and focus The paper must be organised in my custom structure—Abstract, Literature Review, Methodology, Findings, Discussions and Implications—with particular strength in the Analysis and Results content. You will be drawing on up-to-date polymer chemistry and materials-science literature, then translating experimental insights into a clear narrative that highlights how molecular design choices translate into sustained performance at 500 °C, especially under combined acid and thermal stress...

Project Title: Medical Device V&V Testing — Contract Biomedical Engineer (Bay Area, 4-6 weeks) Description: We're an early-stage medical device startup preparing an IRB submission for an early feasibility clinical study of an Intermittent Hypoxic-Hyperoxic Therapy (IHHT) device. We need an experienced contract biomedical engineer to execute verification and validation testing on 3 prototype units in the San Francisco Bay Area, starting mid-April 2026. Scope of work: FiO2 & gas delivery characterization — measure oxygen concentration accuracy across the operating range (8-35% FiO2) using calibrated external oxygen analyzer and flow meter. Continuous logging over extended test sessions to characterize PSA cycling dynamics, transient behavior, and stability. Syste...

I'm looking for a skilled designer to create several items for the Mexican army. The project involves: Uniforms: - Design and fit - Material selection Gear and Equipment: - Design of protective gear Ideal candidates should have experience in military design, strong understanding of functional materials, and an eye for practical and ergonomic design.

I require a fully-formatted, 16-section Safety Data Sheet that meets the latest Globally Harmonised System (GHS) guidelines. The product in question is an industrial-use liquid chemical, so accuracy in hazard identification, classification, and labelling is critical. All content must align with international standards (EU CLP, OSHA HazCom 2012, UN GHS Rev 9 where applicable). I will provide the raw formulation data, test results, and any existing technical sheets; you will transform these into a compliant SDS ready for worldwide distribution. Deliverable • One editable SDS document (Word) plus a print-ready PDF, laid out in the standard 16-section order with correct pictograms, signal words, H- and P-statements, transport information, and regulatory references. Acceptance will ...

I’m looking for a chemist who can take the lead on formulation adjustments for a new set of histopathology-related reagents that will be used in our medical-device line. The core of the assignment is to fine-tune the current formulation, run stability tests to confirm performance. Freelance Formulation Chemist – ISTOS Medical (Histopathology Reagents) Project Scope Support chemical formulation, reagent preparation, and quality validation for histopathology and medical device applications. Responsibilities Develop and prepare chemical formulations for histopathology reagents (stains, buffers, fixatives, mounting media).
