HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots
Advanced Intelligent Systems, EarlyView.A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study analyses the association between carbon emissions and financial performance in Latin American firms. The scientific literature on this topic is limited, with little evidence available in this geographical region. This study aims to address this research gap by testing hypotheses focused on analysing how Scope 1, 2 and 3 carbon ...
