A two-step process for making graphene

A Korean team has developed a carbon material that is as effective as graphene in applications, such as solar cells and semiconductor chips, using a process that requires only two steps instead of the usual eight. High-quality graphene is usually…

These scales require no test weights for calibration

This company’s industrial floor scales are rated for 250,000 load cycles under normal loading conditions. The following load capacities are available: 1,000, 2,500, 5,000 and 10,000 lb. These scales come with a 20-ft cable and have two threaded holes in…

Advanced Control Methods for Combustion

Fuel combustion in engines, power plants, boilers, furnaces and other equipment provides energy for transportation, heating, electricity and goods manufacturing. Optimizing efficiency while lowering pollutant emissions is the main goal of industrial combustion, and reaching those goals, coupled with climate-change…

Dry Separation Methods

The chemical process industries (CPI) have many applications that require classifying or separating solid materials. Examples of separation or classification processes include those operations that attempt to isolate specific material fractions according to particle size, scalp off the coarse fraction…

A Safety Checklist For Laboratories

Laboratories, such as those used for quality control in a production environment and those in research and development, are an integral part of the chemical process industries (CPI). Everyday demands of business can easily overtake safety when it comes to…
