Summary: This study explores the importance and mechanism of chiral self-assembly and self-sorting in gold cluster systems. By introducing ligands with different chirality, unique chiral gold clusters with specific shapes were successfully synthesized. Both homochiral and heterochiral self-sorting processes were observed, as well as the transfer of chirality from ligands to gold clusters, resulting in changes in symmetry.

Summary: Schnockel's [(AlCp*)(4)] and Jutzi's [SiCp*][B(C6F5)(4)] are important in modern main-group chemistry with various applications in synthesis and catalysis. However, the reactivity between AlCp* and [SiCp*](+) has not been explored. In this study, their reaction was investigated and complex salts [Cp*Si(AlCp*)(3)][WCA] were obtained. The tetrahedral [SiAl3](+) core not only represents a rare example of a low-valent silicon-doped aluminium-cluster, but also provides a convenient preparative entry towards low-valent Si-Al clusters.

Summary: This study investigated the self-assembly phenomenon of nucleator DCHT in isotactic polypropylene from the perspective of sublimation and condensation. A correlation between T-c of iPP and T-f was constructed, showing a V shape phenomenon with DCHT concentration dependence. A phase diagram distinguishing assembly structures of DCHT and a schematic condensation mechanism were proposed. Rheology results provided indirect evidence of the condensation process with two steps observed.

Summary: This study demonstrates the preparation and self-assembly of giant molecules composed of vinyl polyhedral oligomeric silsesquioxane (VPOSS) tethered with monodispersed oligo(L-lactide) chains, achieving ultra-small domain sizes of phase-separated lamellar morphology. Small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) results show that the strong tendency and fast kinetics for crystallization of VPOSS moieties drive the formation of ultra-small domain sizes. Upon pyrolysis at high temperature, ultra-thin two-dimensional nano-silica sheets can be obtained.

Summary: This study successfully applied ultrasound technology to control polymorph nucleation. Different ultrasound application methods were proposed based on the nucleation mechanisms. For systems with molecular self-assembly similar to crystal structure synthon, ultrasound pretreatment was used to alter the nucleated form. For systems where molecular self-association couldn't predict the nucleated polymorph, continuous ultrasonic irradiation was introduced during nucleation to accelerate the process and avoid solute molecule rearrangement.

Summary: This study investigates five functionalized hydroxamic acid ligands as potential collectors for the REE-containing bastnasite mineral. Through density functional theory calculations and surface-sensitive analytical spectroscopies, the researchers establish a systematic relationship connecting the ligands' structure to adsorption activity on well-defined mineral surfaces. The inclusion of explicit water solvent molecules is found to be necessary for accurate mapping of energetic and structural trends. The results and insights from this work can inspire and guide the design of improved flotation collectors for REE ores.

Summary: Anionic Te2O6(OH)(4)(4-) dimers were captured and structurally characterized using single-crystal X-ray diffraction and vibrational spectroscopy. The crystal structure revealed the presence of hydrogen-bonded chains of Te2O6(OH)(4)(4-) dimers, stabilized by hydrogen bonding from the GBIG cations and water molecules. FTIR spectroscopy confirmed the presence of TeO6 octahedra and axially-bonded hydroxyl groups, while Raman spectroscopy and DFT calculations suggested the presence of Te2O6(OH)(4)(4-) dimers in the crystalline phase and TeO(OH)(5)(-) monomers in solution.

Summary: Guanidine functional groups are often unstable due to hydrolysis, but by synthesizing guanidines with sterically bulky alkyl substituents and testing their stabilities, researchers have found that the branching of the alkyl group can increase the stability. This research is important for the development of the next-generation caustic-side solvent extraction (NG-CSSX) process for removing radioactive cesium from complex alkaline solutions. The most hydrolysis-resistant guanidine molecule, N,N '-dicyclohexyl-N''-(10-nonadecyl)guanidine (DCNDG), was found to have a stability 8 to 44 times greater than that of the currently used compound (TiDG) under different process conditions.

Summary: This work introduces calix[4]pyrrole-based ion-pair receptors, cis/trans-1 and cis/trans-2, designed for extracting sodium hydroxide. The structure of the cis-1·NaOH isomer was analyzed using X-ray diffraction and revealed a unique dimeric supramolecular structure. The extraction efficiency of NaOH using purified receptors cis- and trans-2 was found to be 50-60%, but precipitation was observed in all cases. Precipitation was avoided by immobilizing the receptors onto a poly(styrene) resin, allowing for lower pH and salinity in the extraction process.

Summary: Selenium (Se) contamination in aquatic ecosystems, caused by human activities such as mining, fossil fuel combustion, and agriculture, has become a major concern. This study presents an efficient approach to remove Se-oxyanions by cocrystallization with bisiminoguanidinium (BIG) ligands, utilizing high sulfate concentrations in wastewaters. The experiments demonstrate near quantitative removal (>99%) of sulfate or selenate from solution, and no discrimination between the two oxyanions during cocrystallization, even in highly concentrated sulfate solutions. This work provides a simple and effective alternative for selective separation of highly toxic selenate oxyanions from wastewaters.

Summary: This study investigated the complexation of two acyclic aminopolycarboxylate chelators with trivalent lanthanides and minor actinides. The chelators, H(4)octapa and H(4)pypa-peg, are suitable for radiometal coordination and f-element isolation. H(4)octapa forms a compact coordination packet, while H(4)pypa-peg is less constrained. The solubility of H(4)pypa-peg is increased by introducing a polyethylene glycol group, without affecting its ability to complex the lanthanides and minor actinides.
