Braskem, a biopolymer producer, and SCG Chemicals, a petrochemical company in Thailand and Southeast Asia, sign a joint venture (JV) agreement to create Braskem Siam Company. The joint venture aims to produce bio-ethylene from bio-ethanol dehydration and to commercialize I'm green™ bio-based polyethylene (PE), using the EtE EverGreen™ technology. The technology results from the partnership agreement between Lummus Technology LLC and Braskem B.V. to develop and license this technology. Sugarcane-derived Polyethylene: I'm green™ bio-based polyethylene is a plastic made from a #sustainably sourced renewable raw material (ethanol from sugar cane) instead of traditional fossil feedstock (e.g., naphtha from oil). This promotes a significant reduction of the plastic's carbon footprint which helps combat climate change. I'm green™ bio-based polyethylene is used in a variety of products, from packaging for food and beverage to personal and home care products, toys, houseware,

Today's KNOWLEDGE Share Do you really understand how important mold temperature is in Injection Molding ? When molding semi-crystalline materials, a higher mold temperature will accelerate crystallization and possibly reduce (Yes, REDUCE) cycle time (see top right kinetic curve), while producing a stiffer part. When molding amorphous polymers, the degree of Physical Aging induced by a higher mold temperature will lead to a higher Yield Stress (left graph) and serious consequences on mechanical response. Creep performance and Impact will change by orders of magnitude, in opposite directions. Many erroneously interpret these effects as being due to residual stresses.

Solar is set to attract more capital than global oil production in 2023 for the first time. This reflects the major shift taking place in energy systems around the world. And it's another sign that clean energy is moving faster than many people think:   https://iea.li/3EhE7G5 Source:Faith Birol Visit MY BLOG  https://lnkd.in/fcSeK9e   

GluECO Adhesives has received the U.S. Department of Agriculture (USDA) certified biobased product label for BondAmaize™ Adhesives. According to the company, BondAmaize™ has been certified as containing 98% biobased content, far exceeding any other #USDA -certified adhesive. In fact, 83% of certified #adhesives contain less than 50% biobased content. Address Climate Change BondAmiaze™ line of adhesives are fully #sustainable and contains renewable raw materials. Formulations can be easily fine-tuned to achieve performance characteristics for specific applications, materials and ambient conditions. GluECO is presently focusing on the packaging, textile, and construction industries. The adhesive can also produce a clear, flexible, food-safe film which is ideal for use as a laminating adhesive for flexible food packaging. BondAmaize™ products can now display a unique USDA label that highlights its percentage of biobased content. Third-party verification for a product's biobased cont

Virginia Tech tire retreading research applies 3D scanning and printing for better commercial truck tires. The  #tire retreading industry applies fresh tread to 4.5 million tires a year, and Mordor Intelligence forecasts the global #retreading market to grow from $5.45 billion this year to $6.41 billion in 2028. While each of these tires represents the reuse of most of a tire, there is still 9 pounds of material removed on average from each of those tires, generating a mountain of waste rubber. Compounding the matter is the fact that the retreaded tires that are commonly used by #commercialtrucks have more rolling resistance than new tires, which causes those trucks to burn more fuel than they would otherwise, said Chris Williams, Professor of Mechanical Engineering at Virginia Tech. The university is working with a former colleague now at the New Mexico and  #michelin to develop #3dscanning and printing techniques and materials that will produce retreaded tires that produce less

The findings point to faster way to detect bacteria in food, water, and clinical samples. Getting results from a blood test can take anywhere from one day to a week, depending on what a test is targeting. The same goes for tests of water pollution and food contamination. And in most cases, the wait time has to do with time-consuming steps in sample processing and analysis. Now, MIT engineers have identified a new optical signature in a widely used class of magnetic beads, which could be used to quickly detect contaminants in a variety of diagnostic tests. For example, the team showed the signature could be used to detect signs of the food contaminant Salmonella. The so-called Dynabeads are microscopic magnetic beads that can be coated with antibodies that bind to target molecules, such as a specific pathogen. Dynabeads are typically used in experiments in which they are mixed into solutions to capture molecules of interest. But from there, scientists have to take additional, time-consu

Today's KNOWLEDGE Share: Jacobus Henricus van 't Hoff-Nobel Prize 1901 Stereochemistry Methane was known to consist of four atoms of hydrogen and one of carbon. It had also been determined that it was a symmetrical compound, meaning that in chemical reactions, other chemicals did not discriminate as to which hydrogen atom they would react to. Van 't Hoff quickly concluded that the only spatial arrangement consistent with this finding was one where the carbon atom lay at the center of a regular tetrahedron (a four-sided figure with equilateral triangles as sides) with each of the other four molecules at a corner of the tetrahedron. This was the first peek that scientists had ventured to take into the three-dimensional structure of molecules. Van 't Hoff claimed as the inspiration for his discovery, Johannes Wislicenus's studies on lactic acid, in which he declares that differences in some chemical properties may be attributable to structural differences in their mole
