Mashup Score: 0Sol-gel processing of a covalent organic framework for the generation of hierarchically porous monolithic adsorbents - 1 year(s) ago
Industrial application of porous materials frequently requires shaping into pellets. However, emerging porous materials are often incompatible with existing methods of pelletization as a result of their limited mechanical stability. Here, we present a simple way to prepare hierarchically porous centimeter-scale covalent organic framework (COF) monoliths. Monoliths thus formed exhibit gas-uptake…

Mashup Score: 1Molecular engineering of interplanar spacing via π-conjugated phenothiazine linkages for high-power 2D covalent organic framework batteries - 1 year(s) ago
A molecular strategy involving the π-conjugated heteroaromatic phenothiazine family to instantly engineer interlayer distance of a two-dimensional covalent organic framework (2D-COF) electrode has been designed, and this facilitates effective and fast Li+ storage between layers, significantly enhancing performance in fast-charging conditions. In-depth mechanistic studies reveal a dual storage…

Mashup Score: 0Supramolecular interactions enable pseudo-nanophase separation for constructing an ion-transport highway - 1 year(s) ago
A pseudo-nanophase-separation strategy enabled by supramolecular interactions is proposed to construct a ion-selective transport highway in polymeric membranes. “Side chains” are “grafted” onto polymer backbones via supramolecular interactions instead of covalent bonds. This simplifies membrane preparation and simultaneously protects backbones from chemical degradation caused by molecular…

Mashup Score: 1Stored photoelectrons in a faradaic junction for decoupled solar hydrogen production in the dark - 1 year(s) ago
Upon irradiation, photoelectrons were stored in a TiOx/CN faradaic junction in a form of TiOxHy for decoupled solar hydrogen generation in the dark. This faradaic junction generates 2.4 mmol/g hydrogen from alkaline methanol within 0.5 h after irradiation, which allows for efficient solar energy utilization under intermittent sunlight.

Mashup Score: 3
Proton-electron dual conductors with a well-defined structure allow for efficient charge transport while promoting a fundamental understanding of dual conduction. Herein, we present Zn-HHTP-H2O, a proton-electron dual-conducting MOF, which serves as a functionalizable platform. We found that substituting H2O with urea leaves electrical conductivity nearly the same while increasing proton…

Mashup Score: 2
The O–H bond dissociation free energies (BDFEs) and their distribution are reported for nickel oxide electrode surfaces. These BDFEs and the H-atom binding isotherms are remarkably independent of any changes in the solvent in contact. The unprecedented medium independence establishes these as important intrinsic parameters to describe metal oxide redox reactivity.

Mashup Score: 0Aqueous rechargeable zinc air batteries operated at −110°C - 1 year(s) ago
The freezing of aqueous electrolytes and the catalytic performance deterioration in electrocatalysts hinder the ultralow-temperature operation of zinc air batteries (ZABs). This work finds that the 8 M KOH electrolyte exhibits a freezing point down to −120°C and develops an ultralow-temperature-tolerant FeCo-PC bifunctional electrocatalyst. This results in a ZAB with unprecedented battery…

Mashup Score: 2Biodegrading plastics with a synthetic non-biodegradable enzyme - 2 year(s) ago
Natural enzymes capable of plastic degradation lack biostability in open environments. Jiang and colleagues chemically synthesized a non-biodegradable plastic-degrading enzyme that is composed of D-amino acids and is capable of degrading a variety of achiral plastics such as polyethylene terephthalate (PET). This work demonstrates a potential approach for gradating plastics in environments that…
