“…As shown in the FT‐IR of TPPS (Figure C; Figure S1, Supporting Information), the peaks at 1506, 1144, 1006, and 800 cm −1 correspond to the deformation vibration of SO 3 − . Also, the peaks correspond to the deformation vibration of SO 3 − because NTP red‐shifted to 1486, 1156, 992, and 831 cm −1 . Furthermore, the S1s spectrum of TPPS possessed two peaks at 168.2 and 169.0 eV, and the S1s spectrum of the NTP possessed two peaks at 168.0 and 168.8 eV.…”

To address the urgent need for effective sonodynamic therapy (SDT), a facile and efficient strategy is developed for fabricating a new class of sonotheranostics. Herein, a Fe(III)-porphyrin nano-sonosensitizer is prepared by a one-step coordination synthesis, and then anchored with Bis(DPA-Zn)-RGD and manganese superoxide dismutase (SOD2) siRNA. Benefiting from the delicate interactions of the Fe(III)-coordinated nanoformulations, a highly potent sono/gene combinational therapy guided by fluorescence/magnetic resonance imaging is achieved. Importantly, this sonotheranostics significantly enhances the SDT effect of porphyrin through the cancer-targeted delivery capability and enhanced reactive oxygen species production via triple-regulated approaches, including down-regulation of SOD2, depletion of glutathione, and generation of Fenton reaction. This work opens up new perspectives for developing versatile sonotheranostics to overcome the clinical challenges of SDT.

This study was carried out for reducing the environmental effects of chromium and sodium chloride resulting in leather tanning process through salt-free pickling, which is considered as the most important way in reducing pollution of sodium chloride in process of chrome tanning. Two aromatic sulphonic acids (naphthalene sulphonic acid and phenol sulphonic acid) were prepared by sulphonation reaction. Thirty sheep pelts were used in tanning process and divided into ten groups where each group contains three pelts. Group 1 was tanned by traditional method as a control group. While the other groups tanned with prepared aromatic sulphonic acids and sulphonic acid in concentrations (2, 3 and 4%) from bating weight. The results showed that salt free pickling acids have ability to reduce total dissolved solids (TDS), chloride content and chemical oxygen demand (COD) compared to traditional method. Also, results indicated that utilization of sulphonic acid with concentration (4%) enhanced chrome exhaustion from 79.62% to 90.10% and reduced Cr (III) in spent liquor from 6.63% to 2.83%. It had no bad influence on the quality of the finished leather as well and was suitable for using in leather manufacturing.

“…Cram , Lehn, and Pedersen raised their study about host–guest chemistry for the first time, and in 1987 they won the Nobel Prize 1 – 5 . Among the various well-known supramolecules such as Calix[n]arenes 6 , cucurbits 7 , and rotaxanes 8 , cyclodextrins and their derivatives are very interesting to study, due to their hydrophobic cavities, and ability to encapsulate small molecules and generate inclusion complexes, which demonstrate host–guest relationships 9 . These compounds are very useful in drug delivery due to their non-toxicity in small amounts 10 , 11 , and in removing pollution from wastewater 12 – 14 .…”

The synthesis of 1,2,3-triazoles with immobilized Cu(I) in thiosemicarbazide-functionalized β-cyclodextrin (Cu@TSC-β‐CD) as a supramolecular catalyst was discussed. The catalyst was characterized by Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) measurements. The catalyst showed high activity (up to 95% yields of triazole products under optimized reaction conditions), providing a one-pot, atom-economic, and highly regioselective green method for 1,2,3-triazoles synthesis in an azide-alkyne cycloaddition (AAC) protocol in water. High stability and no appreciable leaching of Cu(I) were observed, owing to its strong binding via the coordination with thiosemicarbazide functionality.
