Summary: Copper-catalyzed alkyne azide click chemistry (CuAAC) is important for drug development and biological materials labeling. A new tridentate Cu-ligand called TDETA was synthesized as a scalable and non-toxic alternative to HN3 and the previously used DTEA ligand. TDETA showed excellent solubility in organic solvents and aqueous solutions, outcompeted commercial ligands THPTA and TBTA for various azide and alkyne combinations using Cu(I) and Cu(II) species, and had a 80% recovery yield.

Summary: This study rationalized the mechanism of Cu(I)-catalyzed 5-enamine-functionalized fully substituted 1,2,3-triazole synthesis using density functional theory (DFT) and multicomponent artificial force-induced reaction (MC-AFIR) methods. The research provided important mechanistic insights for the interrupted CuAAC reaction and identified the rate-determining step as the transmetalation process along the triplet state potential energy surface. Further predictions suggest the role of solvent and extra strong ligand coordination in competitive reactions.

Summary: Designing selective oil sorption and recovery systems using special-wetting materials has gained significant attention. In this study, a coating material based on functionalized halloysite nanotubes (HNT) supported over fluorinated graphene (FG) nanosheets was developed and analyzed. The HNTC-FG hybrids showed a water contact angle of 145 +/- 2 degrees and a surface free energy of 18.1 mJ/m(2), which significantly affected solvent wettability. The HNTC-FG dispersion was applied onto polyurethane (PU) sponge to carry out oil-water separation. The HNTC-FG-PU sponges showed excellent sorption capacity for various oils and organics, as well as remarkable recyclability and stability. They were also effective in the continuous separation of organic solvents. Overall, the stable hydrophobicity, chemical stability, and recyclability of the HNTC-FG-PU sponges make them suitable for oil/organics recovery prototypes.

Summary: Recent literature on thermoelectric materials has indicated that ionic thermoelectric (i-TE) materials are well-suited for directly converting low-quality waste heat into electricity. In this study, a unique platform for i-TE research was developed by stacking two-dimensional sheets of beta-Ni(OH)(2) using a bottom-up approach. The beta-Ni(OH)(2) lamellar membrane itself does not exhibit significant thermovoltages, but upon doping with anion-generating or cation-generating species, it demonstrates negative and positive Seebeck coefficient values, respectively. The doped i-TE materials were assembled into ionic thermopiles capable of producing thermovoltages up to 1 V at a temperature difference of 12 K. Furthermore, connecting the colder regions of the positive and negative i-TE materials with other ion-conducting membranes in the Ni-M-based nanofluidic systems allowed for additional electricity harvesting.
