Extraction of 2D Cellulose Nanosheets From Natural Cellulose

SusMat, EarlyView.
2D cellulose nanosheets can be selectively extracted from various natural cellulose via precise breaking of their structure using a zwitterion combined solid catalyst. This provides direct evidence of 2D arrangement and challenges the classical fibrillar model, prompting a redefinition of cellulose hierarchy.

Dose‐Dependent Effects of Simulated Clinical Radiotherapy on the Structure and Properties of Root Dentine

Australian Endodontic Journal, EarlyView.
ABSTRACT Head and neck radiotherapy (HNRT) can expose teeth to moderate radiation doses, yet the effects on root dentine under clinically relevant conditions remain unclear. This in vitro study compared dentine subjected to 0, 30, or 50 Gy IMRT. Palatal roots from 35 maxillary molars were allocated to non‐irradiated, 30 Gy (oropharyngeal simulation ...

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Problem‐Solving Strategies for Creativity in Business Model Design: A Configurational Study

Journal of Management Studies, EarlyView.
Abstract We study how individuals develop mental representations of how a business may create and capture value. Specifically, we analyse how different configurations of problem‐solving strategies lead to creative business models. We observe the design process of 101 experienced business‐model designers in real time, using think‐alouds.
