Compositional Stages in the Thermal Activation of Metal‐Organic Frameworks in Vacuo: In Situ Spectroscopy and Computation

Chemistry – A European Journal, EarlyView.
The ultrahigh surface area intrinsic to many metal‐organic frameworks (MOFs) may only be accessed after the removal of synthesis solvent from within the pores. This study elucidates the electronic and structural changes undergone through the guest removal process within a commonly used CUS MOF.

Assessment of Gibbs Free Energy Calculation in PI‐Controlled Heating

Chemie Ingenieur Technik, EarlyView.
For description and control of chemical processes in lab or industry thermodynamic variable Gibbs free energy provides opportunity to compare and interpret phenomena, even on a quantitative level. In a case study for PI‐controlled heating, impacts on its limits from control delay until parameter quantization are highlighted and assessed.

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower

The Canadian Journal of Chemical Engineering, EarlyView.
Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...
