The chemistry of semiconductors - Chemical Engineering

2 weeks ago | chemengonline.com | Dorothy Lozowski

Semiconductors are vital components in the modern technologies that we use in our everyday lives, both in industrial automation and consumer products. Computers, automobile electronics, smartphones and other “smart” devices, robotics and medical devices that depend on semiconductor chips are just a few examples that demonstrate the wide breadth of their applications. The demand for semiconductors is surging.
Trends in automation - Chemical Engineering %

I remember first learning the fundamentals of process control in my undergraduate courses some years ago. Our professor taught the class with a passion for the subject while impressing upon us, his students, how important the subject would be for our future jobs. He was right. Since then, the worlds of process control and automation have advanced by leaps and bounds.

Decrease SizeDefault sizeIncrease Size Print New sustainable materials from recycled carbon nanotubes February 1, 2025 | By Dorothy Lozowski Recycling materials, such as plastics and metals, is an attractive, but challenging path toward sustainable material manufacture. Now, researchers have made a discovery that may have far-reaching implications in material manufacture by positioning carbon nanotube (CNT) fibers as a sustainable alternative to metals, polymers and much larger carbon fibers....
AI’s potential in the CPI - Chemical Engineering

Jan 31, 2025 | chemengonline.com | Dorothy Lozowski

One of the aspects of my job that I really enjoy is keeping in touch with new and advanced technologies emerging from the chemical process industries (CPI) — an interest that traces back to my roots as an R&D engineer. Since products from the CPI are used in just about every facet of our lives, the technologies being developed and scaled up are as varied as the intended applications, and many have far-reaching implications.
New Materials Advance Solar Evaporation for Freshwater Production

Jan 6, 2025 | waterhq.world | Dorothy Lozowski

Efforts to address global water scarcity have driven advancements in technologies for water conservation, re-use, and treatment. Among these, desalination of seawater is a well-established method to combat shortages, although it is known for being energy-intensive. In contrast, solar-powered evaporation offers a more energy-efficient alternative. However, the presence of salt in seawater reduces the evaporation rate, with studies indicating seawater evaporates about 8% slower than pure water.
CPI Outlook for 2025 - Chemical Engineering

Dec 31, 2024 | chemengonline.com | Dorothy Lozowski

The industrial sector consumes more than 80% of basic and specialty chemicals. Worldwide, industrial activity saw a modest recovery in 2024. Global industrial production is expected to have increased by 1.3% by the end of 2024, with predictions of about 2.6% growth in 2025. These findings are according to the American Chemistry Council (ACC; Washington, D.C.; americanchemistry.com) [1].

Typically, hydrogen is produced by steam methane reforming (SMR), a process which itself produces greenhouse gases. Efforts to lower the carbon footprint of hydrogen production include producing “green” hydrogen via electrolysis, using...
Electrochemistry and much more - Chemical Engineering

Nov 30, 2024 | chemengonline.com | Dorothy Lozowski

A couple of years ago on Chemical Engineering’s 120th anniversary, I looked back at the history of this publication and at that time, I wrote: “In September of 1902, the first issue of Electrochemical Industry was published to serve those applying the principles of electrochemistry in industry.
