A pd‐Catalyzed Three‐Component Approach for the Synthesis of Monomeric and Dimeric Tetrahydro‐4H‐Furo[2,3‐b]Chromene Steroids

Journal of Heterocyclic Chemistry, EarlyView.
The three‐component reaction of a steroid bearing a dihydrofuran ring, with methyl orthoformate and salicylaldehyde produced chromanketals. ABSTRACT The three‐component reaction of a steroid bearing a dihydrofuran ring, with methyl orthoformate and salicylaldehyde produced chromanketals through a [4 + 2] inverse electron demand cycloaddition ...

Characterization and Preliminary Investigation of Alkylpolyglucoside Combined With a Biopolymer for Enhanced Oil Recovery

Journal of Surfactants and Detergents, EarlyView.
Materials and main results of the study. ABSTRACT Surfactant–polymer (SP) flooding is a promising Enhanced Oil Recovery (EOR) technique, combining improved displacement from surfactants with enhanced sweep efficiency from polymers. This study investigates two SP systems based on the biopolymer scleroxanthan (a blend of sclerotium gum and xanthan gum ...

Multicentric development and validation of a fully automated artificial intelligence system for planning medial open wedge high tibial osteotomy on weight‐bearing anterior‐posterior long leg radiographs: The ISAKOS John Joyce Award 2025

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Preoperative planning, currently performed by orthopaedic surgeons (OS), is essential for successful osteotomy, but is labour‐intensive and error‐prone. As such, there is significant potential in the use of automated artificial intelligence (AI) algorithms to augment the abilities of OS in managing lower extremity pathologies in a high‐

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.
