Can you take the heat? – Geothermal energy in mining [PDF]
, 2014 In 2013, there are less than 20 documented examples of operational geothermal systems on mine sites worldwide. This is surprising, since on remote mine sites, where fuels may have to be shipped in over great distances, heating and cooling from low ...

4D Printing of Self‐Immolative Polymers
Advanced Functional Materials, EarlyView.The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...

GROUND SOURCE HEAT PUMP OPERATION ANALYSIS
, 2021 The paper analyzes the influence of different parameters on the effective Coefficient of Performance (COP) of a ground source heat pump. Heat pump located in the Laboratory for Thermal Science Engineering at the Faculty of Mechanical Engineering in Belgrade is adopted for model. Since the change in soil temperature more or less depends on the change in

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response
Advanced Functional Materials, EarlyView.This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...
