Preserving federal statistics

Since its introduction in 1963, the Chemical Engineering Plant Cost Index® (CEPCI) has been tracking changes to construction costs for chemical manufacturing and related process facilities. The data from which the CEPCI is calculated come from a carefully selected and…

Transitioning from Academia to the Engineering Workforce

Moving from engineering student to engineering employee can be a challenge, but there are strategies to help facilitate the transition New college graduates provide a continued source of engineering talent to companies, government agencies and other organizations. However, integrating new…

Low-cost graphene-encapsulation technology improves cathode lifetimes

Battery performance tends to degrade over time due to the natural wear that occurs when, for example, cathode active materials (CAMs) expand and contract while shuttling ions for the reversible storage and release of electrical energy. CAMs also degrade due…

Nozzle Penetrations in Pressure Vessels: Two Methods for Reinforcement Design

Pressure vessels are weakened when nozzles must be introduced, and reinforcement is required to compensate. Presented here are two methods for calculating the necessary reinforcement When pressure vessels are penetrated for introducing nozzles, the vessel is weakened and must be…

Destroy PFAS and remove perchlorate in a single process

A new water-treatment process is said to be the first to comprehensively destroy per- and polyfluoroalkyl substances (PFAS) while also eliminating perchlorates. The PFASER technology, developed by WSP Global (Montreal, Que., Canada; www.wsp.com) is an advanced electro-oxidation (EO) treatment system…

Accelerating Speed to Market and Sustainability Outcomes Using Digital Twins

An AI-driven digital twin has fundamentally altered the way new products are developed in the automotive sector Your product might be a game changer. But if it takes two years longer than your competitors to bring it to market, that’s…

Low-capital-cost reactor could bring SAF closer to cost parity with fossil jet fuel

A unique reactor design allows the conversion of raw biogas (methane and carbon dioxide) into synthesis gas (syngas; hydrogen and carbon monoxide) at capital costs 100 times lower than those for gas-fired reformer reactors. Developed by e-fuels startup company Circularity…

Low-energy, application-specific carbon nanotube manufacturing with hydrogen co-product

Due to their strength, electrical conductivity and surface area, carbon nanotubes (CNTs) are increasingly finding application in advanced electronics, energy-storage installations, batteries, medical devices, separation processes and much more. A new CNT production technology developed by the SPICE division of…

Protein nanocages: Selective mini-concentrators for critical metals

Protein nanocages are hollow structures that can be used for a variety of applications in medical fields, including for drug and vaccine delivery. Now, groundbreaking work from the University of Pittsburgh (Pitt; www.pitt.edu) has shown that a class of protein…

New techniques improve abilities of hybrid quantum-classical computer systems in catalyst design

By leveraging the peculiar laws of quantum physics, quantum computing aims to render currently intractable scientific problems feasible. Using quantum-enhanced simulations for accelerating catalyst design is an example of an area where quantum computers could be brought to bear on…
