Photogrammetric documentation in tunneling

Civil Engineering Design, EarlyView.
Abstract Photogrammetric surveys for geological excavation documentation are standard practice in tunnel construction, benefiting from the sector's ongoing digitalization. However, the application of photogrammetry often remains confined to geological assessments. By creating comprehensive 3D models of excavated tunnels, it is also possible to evaluate

Thermally Activated On‐Surface Self‐Metalation of Pd‐Phthalocyanines

Chemistry – A European Journal, EarlyView.
Surfaces enable scalable reactions. Here, Pd(001) drives the self‐metalation of H2Pc${\rm H}_2{\rm Pc}$, where the molecule captures a substrate atom to form PdPc. Spectroscopy reveals the reaction pathway, marking the first demonstration of phthalocyanine self‐metalation on Pd.

Evaluating the feasibility of using a rapeseed oil‐derived anionic polymeric surfactant for enhanced oil recovery from carbonate/sandstone composite reservoirs

The Canadian Journal of Chemical Engineering, EarlyView.
The experimental procedure for evaluating the rapeseed oil‐based polymeric surfactant in enhanced oil recovery. Abstract This study aims to investigate enhanced oil recovery from carbonate/sandstone composite (CSC) reservoirs using a negative‐charged rapeseed oil‐based polymeric surfactant.
