Harmless viruses trap Salmonella on flexible polymer in portable microfluidic sensor
Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica), an advance that could lead to new ways of finding contamination in the food supply. The work is published in the journal ACS Applied Bio Materials...Read More>>>

Principles of Polyurethane
Tough Urethanes for Tough Applications
What is Polyurethane?
Originating during World War II as an alternative to rubber, polyurethane evolved from a laboratory curiosity into an
industrial product. Combining the outstanding properties of rigid plastic, metals, and rubbers, a superior plastic was
born. What sets polyurethane apart from other elastomers and steel is its resilience and overall toughness.

Advantages of Polyurethane
Polyurethane compounds possess an extraordinary combination of physical, mechanical, and environmental properties. The type of resin and the ratio between the resin and the curative can be varied to optimize some of these properties

Polyurethane Application Comparisons
Polyurethanes have definite advantages over plastics, conventional rubber and metals which make them a better substitute in applications where these materials are normally used...Learn More>>> https://files.constantcontact.com/66f9c93f701/047d7b40-d766-4ffe-a844-d02b15f6b25d.pdf?rdr=true

This plastic is made from milk and it vanishes in 13 weeks
Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form a thin, durable material designed to mimic everyday plastic. In soil tests, the film fully broke down in about 13 weeks, pointing to a realistic alternative for single-use food packaging...Read More>>>

Why building Smart Factories begins with data governance… and not before
Since the Industry 4.0 revolution, smart factories have become a tried-and-tested staple of modern manufacturing. Many organizations have already used automation to create more efficient, connected operations. However, those early successes, combined with the rapid emergence of technologies such as AI, have triggered an industry-wide race to catch up, or even overtake, those perceived to be ahead...Read More>>> https://www.manufacturingtomorrow.com/article/2026/03/why-building-smart-factories-begins-with-data-governance%E2%80%A6-and-not-before/27123
