The neutron Bragg-edge imaging is expected to be a new non-destructive energy-resolved neutron imaging technique for quantitatively two-dimensional or three-dimensional visualizing crystallographic information in a bulk material,which could be benefited from pulsed neutron source.Here we build a Bragg-edge imaging system on the General Purpose Powder Diffractometer at the China Spallation Neutron Source.The residual strain mapping of a bent Q235 ferrite steel sample has been achieved with a spectral resolution of 0.15%by the time-of-flight neutron Bragg-edge imaging on this system.The results show its great potential applications in materials science and engineering. 展开更多

Natural adhesives have been widely replaced by industrial adhesives made from petroleum-based products.Compared with that of traditional natural adhesives,modern industrial adhesives show improved adhesion performance.However,the drawbacks of modern adhesives,including toxicity and nonbiodegradability,drive the need for new and high-performance adhesive materials from renewable and biocompatible natural feedstock.In this study,a new family of acid-sugar adhesive materials exhibiting excellent and long-term adhesion effects was developed inspired by the concept of deep eutectic solvents(DESs).The supramolecular polymerization between natural sugars and acids gave rise to both strong cohesion and adhesion properties.Moreover,high resistance to organic solvents is an advantage of acid-sugar supramolecular adhesive materials.This study not only dramatically expands the applications of DESs but also sheds light on the development of supramolecular adhesive materials as promising alternatives to polymeric adhesives. 展开更多
