In the field of flat panel displays (FPD), packaging technology has significant influence on display performance. The electrical and mechanical interconnect between the liquid crystal displays (LCD) and its driver integrated circuit (IC) is a key issue that needs improvement to achieve finer pitch, easier assembly and greater connection reliability. With the decrease of the pixel size and the i...

The resulting internal stress situation in curing dental composites is still oversimplified due to analytical inaccessibility of local information of state and loading. Similar applies to the strength behavior of cured dental composites. Using recent progress of a finite-element-based curing model, we developed and attempted to benchmark dental composites based on their mechanical behavior and ...

Carbohydrates as a component in adhesive formulations have been reported for many years. A rapid cure at moderate temperatures is remaining challenge the development of renewable adhesives. Rheology provides insight into all stages structure formation cured polymer. This work analyses curing carbohydrate-amine adhesives with and without addition 5-hydroxymethylfurfural (HMF) biomass-derived key...

Lignin has been studied as an adhesive for more than 100 years, but there are only a few industrial applications. The reason for the current interest is the high availability and low price of lignin. Lignin is the main by-product of paper pulping processes and is typically burned as fuel. Being the natural glue in plants and having a phenolic nature makes lignins an attractive replacement for w...

Bonding of polymer-based microfluidics to polymer substrates still poses a challenge for Lab-On-a-Chip applications. Especially, when sensing elements are incorporated, patterned deposition of adhesives with curing at ambient conditions is required. Here, we demonstrate a fabrication method for fully printed microfluidic systems with sensing elements using inkjet and stereolithographic 3D-print...

objective: the aim of the present study was to compare microtensile bond strengths (μtbs) of glass fiber posts to different parts of intra-radicular dentin using conventional method and one-shot technique under different light intensities. materials and methods: twenty-eight single-rooted teeth were prepared to receive fiber posts: group 1: conventional method at light intensity of 600 mw/cm2; ...
