A theoretical model for the dependence of the diode forward voltage (V/sub f/) on junction temperature (T) is developed. A new expression for dV/sub f//dT is derived that takes into account all ...

MIT researchers have developed a clever 3D printing trick that could save materials and simplify cleanup. What sets it apart ...

In this paper, we propose a design of LED UV-curing system for automated industrial production lines. The main novelty of this design is the application of compact packaged UV-LED module. The optical ...

Additionally, because the resin is thicker, you can use it to build up repairs more effectively and easily than with ...

Elegoo’s Mercury XS Wash & Cure bundle excels in its capabilities, going above and beyond for high-volume printing needs.

In recent years, 3d resin printer technology has evolved rapidly, bringing professional-grade capabilities into the hands of hobbyists and scaling up for indust ...

High light curing, which is compensated by the intensity, can polymerize the resin composite in a shorter time. However, these high light intensities do not allow enough flow for reducing internal ...

What is ultraviolet light, and where does it come from? Learn how UV radiation is classified, measured, and used in medicine, manufacturing, astronomy, and daily life, plus how to stay safe.

Reducing your time in the sun when the UV index is high (especially in summer) is one of the most effective ways to protect your eyes. Protect your eyes year-round: Remember that UV eye damage is ...

Adequate polymerization plays an important role on the longevity of the composite resin restorations. OBJECTIVES: The aim of this study was to evaluate the effect of light-curing units, curing mode ...

Hybrid film coatings obtained by the sol–gel process are based on two important reactions: hydrolysis and condensation. Their kinetics varies with the curing temperature, which modifies the intrinsic ...
