P-Type Boron Carbon Nitride wafer growth shows useful device metrics, CMOS relevance, and unresolved manufacturing questions.

EPA SNURs for 19 chemicals take effect December 14, 2026, creating 90-day SNUN duties for designated new uses.

U.S. chemical manufacturers and industrial employers face an important workplace safety deadline on November 20, 2026. By that date, employers must update relevant workplace labels, written hazard communication programs and employee training, where necessary, to reflect newly identified hazards of chemical substances under OSHA's revised Hazard Communication Standard. The deadline does not mean every industrial…

The U.S. Environmental Protection Agency is asking chemical manufacturers, waste generators and laboratories whether its long-established hazardous-waste testing methods need to change. The review includes the Toxicity Characteristic Leaching Procedure (TCLP), a laboratory method used to assess how certain contaminants may leach from waste under specified conditions. The comment deadline is November 13, 2026, according…

A titanium dioxide supplier reports high electrical resistivity in a pigment's water extract, while another reports a lower percentage of water-soluble matter. Which pigment is cleaner? Neither result can answer that question alone. Electrical conductivity and water-soluble matter are different measurements. Conductivity indicates how readily an aqueous extract carries electrical current. Water-soluble matter measures the…

A titanium dioxide supplier reports a Hegman grind reading of 7, while another provides a median particle size of 0.3 micrometres. Both numbers may be accurate, but they do not describe the same property and cannot be used to rank the pigments directly. A Hegman grind gauge helps identify coarse particles and agglomerates remaining in…
