Cascade Promotion of Gas Separation Performances in CMS Membranes: MOFs With Functional Groups and Loaded Noble Metals

open access: yesAdvanced Science, EarlyView.
Novel mixed‐matrix carbon molecular sieve (MMCMS) membranes are fabricated via employing palladium‐doped carboxyl‐functionalized UiO‐66 (Pd/UiO66‐COOH)/polyimide MMM as precursor. The synergistic effect of decarboxylation‐induced thermally cross‐linking and catalytic graphitization of Pd promoted the formation of more ordered Langmuir domains, thereby ...

High‐Throughput Tiling of Essential mRNAs Increases Potency of Antisense Antibiotics

open access: yesAdvanced Science, EarlyView.
The systematic tiling of essential genes’ mRNA here presented, proposes a valuable tool for the identification of novel PNA sequences with antibiotic potential. The high‐throughput synthetic set up opens the door to investigating thousands of sequences in an economic way and ultimately identifies potent antisense oligonucleotides while also giving room

Polarographic behavior of acetate ions in acetic anhydride.

open access: yesBUNSEKI KAGAKU, 1983
The half-wave potential (E1/2) of the anodic wave of acetate ion (AcO-) shifted more positively in the presence of alkali metal cations (M+) than in the presence of tetraalkylammonium cations. The difference of E1/2 was caused by ion-pair formation between AcO- and M+.

An Osteoconductive Janus Hydrogel with Full Barrier Protection and Adaptable Degradation Properties for Superior Bone Regeneration

open access: yesAdvanced Science, EarlyView.
The filler‐barrier hydrogel system developed by dual‐network Janus structural strategy breaks through the difficulty of a single hydrogel to combine barrier protection with bone regeneration, and realizes the regeneration‐material degradation adaptation for the field of mandibular regeneration.
