Supramolecular Protection–Deprotection for Switching Pore‐Surface Functionality in a Crystalline Porous Organic Salt

Angewandte Chemie, EarlyView.
A supramolecular protection–deprotection strategy temporally separates the framework construction from pore‐surface activation in a porous organic salt. In Form I, phenolic OH groups are protected by DMSO, enabling framework formation. Stepwise single‐crystal‐to‐single‐crystal phase transformation (SCSC) affords a dormant intermediate (Form II ...

Quine's Platonism

Journal for the History of Analytical Philosophy
Quine’s stance towards mathematical entities is usually divided into two phases. Until 1948 he sympathised with nominalism and the rejection of abstract objects, but then concluded that they are indispensable and accepted mathematical Platonism.

Platonic sphalerons

Physics Letters B, 2004
We construct sphaleron solutions in Weinberg-Salam theory, which possess only discrete symmetries. Related to rational maps of degree N, these sphalerons carry baryon number Q_B=N/2. The energy density of these sphalerons reflects their discrete symmetries.

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Taming Flexibility: Synergistic Pore and Polarity Engineering in a MOF for High‐Efficiency Xe/Kr Separation

Advanced Science, EarlyView.
Through a mixed‐ligand strategy that precisely regulates pore size and framework polarity, the Xe adsorption behavior is transformed from flexible to near‐rigid. ZIF‐7‐Cl(20) achieves sensitive recognition, efficient capture, and high selectivity for Xe, enabling high‐efficiency separation from Xe/Kr mixtures.
