Published: January 2016

A new acid/base controllable host-guest system based on a triptycene-derived macrotricyclic host and protonated 4,4'-bipyridinium/pyridinium salts was developed. Moreover, the competition complexation process between the host and two different kinds of 4,4'-bipyridinium salts could also be chemically controlled by acid and base.

The endoplasmic reticulum (ER) is a vital organelle responsible for protein quality control, including the folding, modification, and transport of proteins. When misfolded or unfolded proteins accumulate in the ER, it triggers endoplasmic reticulum stress (ERS) and activates the unfolded protein response (UPR) to restore ER homeostasis. However, prolonged or excessive ERS can lead to apoptosis.

In nuclear wastewater treatment, ion-scavenging materials designed to trap TcO is urgently needed. However, strong acid/base, high radiation and high salt concentration of nuclear wastewater usually result in inadequate stability and adsorption capacity of the adsorbent. Herein, we report a new class of bifunctional anion-exchange olefin-linked COF (BPDC-MTMP) prepared via Knoevenagel condensation reactions, the first example exploring the synergistic integration of positively charged fragments at both nodes and linkers.

Challenges in CO capture, CO crossover, product separation, and electrolyte recovery hinder electrocatalytic CO reduction (COR). Here, we present an integrated electrochemical recovery and separation system (ERSS) with an ion separation module (ISM) between the anode and cathode of a water electrolysis system. During ERSS operation, protons from the anolyte flow through the anodic cation exchange membrane (CEM) into the ISM, acidifying the COR effluent electrolyte.
