AI in chemical engineering: From promise to practice

AIChE Journal, Volume 72, Issue 7, July 2026.
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.

Gastroscopic Evaluation of Gastric Mucosa in Horses Treated With Flunixin Meglumine or High‐Dose Firocoxib: A Descriptive Pilot Study

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
In this descriptive pilot study, short‐term (5‐day) high‐dose firocoxib (1.0 mg/kg) was not associated with detectable gastric mucosal injury in horses. Due to non‐randomised design and small sample size (n = 5/group), no causal conclusions can be drawn. Findings are hypothesis‐generating and require confirmation in adequately powered trials.

Development and validation of a 3D printed phantom for image quality assessment in fluoroscopy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Low‐contrast detectability is a key image‐quality parameter in fluoroscopy, directly influencing diagnostic accuracy and patient safety. Commercial phantoms such as the CDRAD provide reliable assessments but are costly and lack flexibility for routine use. Purpose To develop and validate a low‐cost 3D‐printed phantom for fluoroscopy
