ZEMU Making United States Debut

-

 On October 24, 2022, the San Bernardino County Transportation Authority (SBCTA), in partnership with the Southern California Regional Rail Authority, expanded the public transit network in the San Bernardino Valley. This addition to the network is primarily using the state-of-the-art Arrow diesel multiple units (DMUs). One of SBCTA’s initiatives, however, is to reduce greenhouse gas (GHG) emissions and improve air quality. The Arrow DMUs are powered via a Tier 4 diesel engine “generator” that provides power to electric motors at the wheels.








Taking it one step further, SBCTA recognized an opportunity to convert the power generator to an alternative propulsion technology in an effort to produce a low or zero emission multiple unit (ZEMU) that could run on the existing heavy rail infrastructure, thus reducing air quality impacts while furthering the use of existing rail infrastructure. And, with the funding support from the California State Transportation Agency (CalSTA), the innovative solution of a zero-emission multiple unit (ZEMU) was launched.

In November 2019, the contract with Stadler US, Inc. (Stadler) for the production of the ZEMU was executed. Design of the vehicle commenced shortly after the contract execution and Stadler began manufacturing of the vehicle in the summer of 2021 with components similar to the DMUs and while further refining the hydrogen propulsion technology. The ZEMU vehicle assembly was completed in mid-2022 and unveiled at InnoTrans, an international trade and visitor fair for transport technology, in September 2022. Dynamic testing in Switzerland began in December 2022 and is wrapping up in preparation for shipment to the United States at the end of June 2023.

Staff is still working through scheduling and logistical details for testing, and the manufacturer is looking to showcase the vehicle at the American Public Transportation Association (APTA) TRANSform Conference & Expo (APTA Expo) in Orlando, Florida, in October – bringing even more recognition for SBCTA and CalSTA as innovators in transportation solutions. Integration into Metrolink’s revenue service in San Bernardino County’s east valley is anticipated for late 2024.

Today's KNOWLEDGE Share:PLA BOTTLE

-

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio

Today's KNOWLEDGE Share : biobased content of polycarbonate diols

Today's KNOWLEDGE Share MCG increases biomass content of polycarbonate diols Mitsubishi Chemical Group (MCG) has introduced grades of its Benebiol biomass-based polycarbonate diols that have a higher biomass content. The product is primarily used in the manufacture of polyurethane resins for coatings in sectors such as automotive, furniture and outdoor products. It is also used in the production of artificial leather. Existing Benebiol grades had a bio-based content of 20-50%, but the new HSS and NLDS grades have a biomass content in excess of 80%. Some of its previous petroleum-derived grades have also been converted to biomass, as the NLS grades. This, the company said, allows it to offer bio-based grades of all its Benebiol products. The shift to biomass-based raw materials while maintaining high-quality functions will contribute to our customers’ efforts to achieve sustainable manufacturing. source:MCG/www.utech-polyurethane.com
