Analysis of the economic viability and environmental impacts of a conceptual process model for the recovery of lactic acid from spent media in cultivated meat production

open access: yesBiotechnology Progress, EarlyView.
Abstract Scaled production of cultivated meat (CM) will co‐produce large volumes of spent media. Recycling of abundant metabolites such as lactic acid in spent media offers an opportunity for valorization and reduction of the carbon footprint of CM production; however, the feasibility has yet to be examined.

Commissural Misalignment Following Valve‐in‐Valve Transcatheter Aortic Valve Implantation

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data on commissural misalignment (CMA) during valve‐in‐valve transcatheter aortic valve implantation (ViV‐TAVI) for valve failure after surgical aortic valve replacement (SAVR) is scarce. Aims To study the impact of CMA on clinical and hemodynamic outcomes following ViV‐TAVI for failed SAVR.

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

Metasurface Enhanced Photothermal Cement Foam for Robust and High‐Throughput Seawater Desalination

open access: yesCarbon Energy, EarlyView.
Schematic of 3D metasurface‐enhanced cement foam for robust and high‐throughput seawater desalination. This study presents a cement‐based solar evaporator (CSE) fabricated in one step via viscoelastic lithography with simple negative pressure. In addition to boosting solar‐to‐vapor conversion efficiency via excellent light‐harvesting capacity, the ...

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.
