Hyperpolarization of [1‐13C]Ketoisocaproate‐d2 by Reversible Exchange with Parahydrogen Enables Profiling of Branched‐Chain‐Amino‐Acid Metabolism in Cellulo and in Vivo

Advanced Science, EarlyView.
We report the fast generation of biocompatible solutions of highly 13C‐hyperpolarized (≈11%) partially‐deuterated ketoisocaproate within <6 min using spin‐lock‐induced crossing and reversible exchange with parahydrogen (SLIC‐SABRE). This enables rapid detection of branched‐chain‐amino‐acid transferase 1 (BCAT1) protein expression and investigation of ...

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

Advanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Fouling‐Free Inertial Microfluidic Cell Clarification for Lentivirus Manufacturing

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Lentiviral vectors (LVVs) are widely used as gene‐delivery vehicles in cell and gene therapy, enabling stable integration of transgenes into target cells. However, efficient clarification of LVV harvest remains a major bottleneck in large‐scale manufacturing, as conventional depth filtration often results in significant product loss.

Signalling ESG Misconduct: What Matters to Investors?

Business Strategy and the Environment, EarlyView.
ABSTRACT We investigate what matters most to investors when environmental, social and governance (ESG)‐related corporate misconduct news is signalled and how these factors influence the magnitude of market value punishment. Using an event study on 44,859 corporate news items related to ESG incidents, we find that investors react negatively to such ...
