2020
Impact print-type hot embossing technology uses an impact header to engrave dot patterns on flexible materials in real time. This technology has a control system for controlling the on-off motion and position of the impact header to create dot patterns with various widths and depths on different polymer films.

Source: Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Working with extreme temperatures, both high and low, is an integral part of many laboratory operations. For many, mentioning a laboratory instantly evokes the mental picture of a Bunsen burner. Bunsen burners and hot plates are used extensively in small and large operations in research laboratories and industries, thus making it necessary for all users to be aware of their safe handling...

Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Hot-wire anemometers have a very short time-response, which makes them ideal to measure rapidly fluctuating phenomena such as turbulent flows. The purpose of this experiment is to demonstrate the use of hot-wire anemometry.

A micropunching lithography approach is developed to generate micro- and submicron-patterns on top, sidewall and bottom surfaces of polymer substrates. It overcomes the obstacles of patterning conducting polymers and generating sidewall patterns. This method allows rapid fabrication of multiple features and is free of aggressive chemistry.

Hot Weather Concreting

2024
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing. Mitigating the heat increase in concrete can be economically achieved by shading aggregate stockpiles to prevent heating from solar radiation,...
FAQs
Heating the thermoplastic polymer above its glass-transition temperature softens it enough to accept the mold’s microscale pattern. The material can therefore conform to the intended geometry under pressure without remaining permanently fluid. This temperature-dependent change is central to producing defined channels, surfaces, and other structures that retain their shape after cooling.
The patterned mold transfers the desired microscale geometry into the softened polymer, so its features determine the arrangement and shape of the replicated structures. Consistent mold-pattern transfer supports reproducible geometries across devices. In biological research, that consistency helps researchers compare fluid behavior, cell organization, or analyte detection under controlled structural conditions.
Cooling allows the embossed thermoplastic polymer to solidify while it remains in the formed configuration. This preserves the microscale features produced during pressing and helps maintain the intended device geometry. The resulting solid structures can then serve as channels, culture surfaces, biosensor components, or scaffold features in subsequent biological experiments.
A typical workflow requires a thermoplastic polymer, a patterned mold, and conditions that support heating, pressing, and cooling. The polymer provides the formable material, while the mold supplies the microscale geometry. Controlling these stages enables researchers to produce structures with the reproducibility needed for microfluidic and biomedical platforms.
Embossed microscale channels provide defined pathways for fluid movement within lab-on-a-chip systems. Their reproducible geometries help researchers control fluid flow, which is important when biological platforms must guide or manage small-scale liquid transport. The same fabrication approach can also be combined with biosensor components or cell-related structures in integrated research devices.
Applications include microfluidic channels, cell-culture substrates, biosensor components, and tissue-engineering scaffolds. These structures address different biological needs: channels help control fluid flow, culture substrates help influence cell organization, biosensor components support analyte detection, and scaffolds provide defined geometries for tissue-engineering research.
