WebbAbstract This study aimed to evaluate the shape-memory effect (SME) of wood (Populus x beijingensis W. Y. Hsu) and identify the net-points and switches in its molecular and morphological structures. During several cycles of deformation and subsequent recovery, a high shape recovery rate and ratio were maintained. The transverse compression tests … In a classical one-way shape-memory effect, the first stage is the definition of a shape-shifting pathway using external physical manipulation, termed programming (Fig. 1). Of note, a shape change introduced during the fabrication process, for example, by lithography, should not be viewed as programming, … Visa mer Shape-memory behaviour in polymeric systems relies on the controlled storage of entropic energy, the subsequent release of which drives the shape change. The entropic energy is generated by conformational … Visa mer In a two-way reversible shape-memory effect, a bidirectional reversible actuation is enabled by conformational changes of the pre-oriented actuating polymer segments within the … Visa mer During a one-way shape-memory effect, the thermal energy derived from external temperature increase causes a phase change, for example, by overcoming the melting enthalpy of … Visa mer philippe hawotte

Webb Each year, Canadian homes and buildings—and the electricity generated to power them—release 111 million tonnes of greenhouse gas (GHG) emissions into the atmosphere. To limit the impact, the Government of Canada aims to reduce GHG emissions 40–45% by 2030, compared to levels in 2005. And heat pumps are emerging … philippe hecky
