The ammonium molybdophosphate (AMP) with excellent ability of separation and extraction for radioisotope 137Cs and Cs+ in saline has a high solubility in water, which avoids its adsorbent role to extract Cs+ from enhydrous solutions directly. In our paper, the copolymers as the carrier of AMP are prepared via RAFT (reversible addition-fragmentation...

Rubidium and cesium play increasingly important roles in high-tech fields such as aerospace engineering, arms development, and perovskite solar cell fabrication owing to their unique physical and chemical properties. Noting that abundant reserves of rubidium and cesium are often found in the brine of salt lakes, efficiently separating and extractin...

Triacetone triperoxide (TATP) is a new terrorist explosive, and most nitrogen-based sensors fail to detect TATP. Herein, a sea urchin-like TiO2-covered TiO2 nanoarray is constructed as a TATP-sensitive homojunction (HJ) by one step hydrothermal method. By taking fluorine-doped tin oxide (FTO) and indium tin oxide (ITO) conducting glass as the subst...

The phosphoric acid-based metakaolin geopolymers were prepared by regulating H3PO4/Al2O3 ratios. X-ray diffraction (XRD), thermogravimetry and differential scanning calorimeter (TG-DSC), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to determine the reaction process and phase formation. The results...

Building novel functional nanomaterials with a polymer is one of the most dynamic research fields at present. Here, three amphiphilic block copolymers of 8-hydroxyquinoline derivative motifs (MQ) with excellent coordination function were synthesized by Reversible Addition-Fragmentation Chain Transfer Polymerization (RAFT) polymerization. The coordi...

... Numerous options for the extraction and sorption of cesium and strontium from HLW can be found in reviews. [2][3][4][5][6] The most frequently used extractants are derivatives of 18-crown-6, 21-crown-7 or calix [4]arene-crown ethers for cesium recovery [2] and substituted 18-crown-6 for strontium recovery [4,7] or their mixtures for the joint extraction of cesium and strontium. [8] Aliphatic alcohols and their mixtures with paraffins, [7][8][9] fluorinated telomer alcohols and their mixtures, [10,11] and ionic liquids [12,13] are mainly used as diluents for crown ethers and calix-crown ethers. ...
... The excitation effect of raw materials is not good when the amount of phosphoric acid is insufficient, while the excessive [PO 4 ] 3− unit will cause a charge imbalance when the amount of phosphoric acid is too high, resulting in a looser microstructure and decreased mechanical properties and water resistance of ASP geopolymers [56]. In addition, too much phosphoric acid will also lead to an increase in the volume shrinkage, cracking rate, porosity, and pore size of the geopolymer matrix [68]. At present, scholars generally believe that the compressive strength will first increase and then decrease with increasing concentrations of phosphoric acid, but the understanding of the optimal phosphoric acid concentration or Al/P ratio is still a problem that cannot be unified. ...
... The ten published papers reflect the original spirit of the Special Issue, ranging from nanoparticles [1,2] to thin films [3][4][5][6][7][8] to heterostructures [9] and homojunctions [10] and covering various aspects of oxide-materials preparation, characterization, and applications. ...
