MOFs as New Catalytic Platform for Covalent Adaptable Networks: Catalysis Meets Reinforcement

Angewandte Chemie International Edition, EarlyView.
A novel heterogeneous catalytic platform for covalent adaptable networks (CANs) is introduced by immobilizing bases of low molecular weight on metal‐organic frameworks (MOFs). The obtained catalyst UiO‐TBD benefits from the high loading capacity of the MOF and demonstrates a higher thermal stability relative to free TBD.

Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries

Batteries &Supercaps, EarlyView.
Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.

Improving Organic Acid Secretion of Aspergillus niger by Overexpression C4-Dicarboxylic Acid Transporters

Fermentation
C4-dicarboxylic acids are essential organic compounds characterized by a four-carbon structure and two carboxyl groups. Their export from cells is mediated by specialized transporter proteins known as C4-dicarboxylic acid transporters (DCTs).

A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

BMEMat, EarlyView.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐
