What are Micro-electronic Sources?

Applications

These types of thermal evaporation sources measure under 2 inches and enable coating applications with limited power systems at more affordable prices. Because of their size, micro-electronic sources require less power to get up to temperature.

 

Material Cost-Effectiveness

Coating methods such as e-beam or sputtering require a minimum fill level or utilize expensive targets, discouraging small-scale applications.

 

Micro-electronic sources work well in cases where only small amounts of evaporation material is needed. This makes them particularly useful for one-off coatings or other small batch applications.

World-first solar thermal demonstrator targets net zero breakthrough for industry and agriculture

| University of South Australia |

Leveraging more than a decade of research into durable, weather-resistant reflective coatings, the project – funded by the Federal Government’s Australia’s Economic Accelerator (AEA) Ignite program – will fabricate and install a novel, two-module CST demonstrator incorporating the mirrors.

 

The panels incorporate a multilayer aluminium-silica reflective coating developed by UniSA’s Future Industries Institute, applied via a physical vapour deposition to ensure durability and optimal solar reflectivity. Dr Llusca Jane says the AEA funding is critical to the project’s success.

  • Technical Tip
S21-AOMaximizing Boat Lifetime

Over time, boats will need to be replaced as they go through cycles of extreme heat and cooling down. However, some materials, when molten, can alloy or corrode through metals.

 

Improper boat selection can lead to source failure, causing unnecessary inefficiencies in your thin film coating process.

 

  1. Take into account material thickness. Thicker material will be able to withstand more corrosion when compared to thinner boats.
  2. Consider adding tungsten wire mixture to the boat. Tungsten mix allows material to wet to it, preventing migration or splattering. This mix also acts as sacrificial clippings against corrosion.
  3. Utilize aluminum oxide when applicable. Alumina coatings are chemically inert to most materials, protecting refractory boats from reacting with evaporation materials.

Less is more: Efficient hydrogen production with less precious metals

| University of Twente |

In a step towards sustainable energy, a team of researchers at the University of Twente led by Dr. Marco Altomare has demonstrated a new method to reduce the use of precious metals such as platinum in green hydrogen production without sacrificing performance.

 

Polymer electrolyte membrane (PEM) water electrolyzers and fuel cells use precious metal catalysts such as platinum and iridium to make hydrogen production and conversion as efficient as possible. However, these catalysts are expensive and scarce and thus limit large-scale development of hydrogen technologies.
