Controlling defectivity levels after the CMP process is critical for yield enhancement. CMP tools are equipped with an in-situ cleaning module to remove polishing byproducts, residues, and flakes.

Key Takeaway Titanium dioxide is a natural ingredient commonly found in mineral sunscreens.Mineral sunscreens with titanium ...

Titanium is a critical mineral with many high-tech applications but new supplies are needed to keep up with demand growth.

Tungsten dioxide imbedded in mesoporous carbon (WO2–MC) was obtained by in situ synthesis and then introduced into dye-sensitized solar cells (DSCs) as a counter electrode (CE) catalyst. Catalytic ...

MANILA, Philippines — Sulfur dioxide emissions from Kanlaon Volcano on Negros Island more than doubled in the past 24 hours, reaching 4,356 tons compared to 1,973 tons the previous day, the ...

The three acquired claims cover an area of 1,100 acres and host a historic resource of 409,300 tonnes at 0.48% WO₃ (tungsten trioxide) and 0.134% MoS₂ (molybdenum disulfide), all within the ...

The electrochemical carbon dioxide reduction reaction (CO2RR) is a promising means of carbon capture and use. The reaction not only removes carbon dioxide from the atmosphere but also transforms ...

The claims total 1,100.6 acres and host a historic resource of 409,300 tonnes at 0.48% WO₃ (tungsten trioxide) and 0.134% MoS₂ (molybdenum disulfide) in the Kuhn North zone.

Electrocatalytic reduction of carbon dioxide into value-added chemical fuels is a promising way to achieve carbon neutrality. Bismuth-based materials have been considered as favorable electrocatalysts ...

[SMM Tungsten Daily Review: Tungsten Market Shows Divergence, Upstream Ore Prices Fluctuate at Highs, Downstream Under Pressure] Today, the tungsten market experienced a slight drop. From the ...

Carbon dioxide peaks during the Northern Hemisphere spring. You’ll notice that there is a distinct sawtooth pattern in charts that show how carbon dioxide is changing over time. There are peaks and ...

Tungsten prices slumped in 2015, and none has been mined in Canada or the United States since then, according to Natural Resources Canada. More recently, things have turned around.
