Summary: Due to the unique geometric structure of dendritic amphiphiles, their micelles can provide a large void space, which offers a new research focus and approach for micellar functionalization. In this study, we used the void space to construct a UV-responsive micelle system of mixed dendritic amphiphile and cationic azobenzene surfactant. The results showed that the micelles can inhibit the UV response of the trans-isomer and activate the thermal relaxation of the cis-isomer, suggesting potential applications in light-controlled smart nanocarriers.

Summary: The corrosion inhibition effect of Artemisia capillaris leaf extract (ACLE) on Q235 steel in 1 M HCl at temperatures ranging from 25-65°C was analyzed using weight loss measurements, electrochemical tests, and quantum chemical calculations. ACLE was found to have a significant corrosion inhibition effect, with an inhibition efficiency of 99% at 10 g/L ACLE at 25°C. Caffeic acid was identified as a major effective corrosion inhibition component in ACLE. The adsorption of ACLE on the Q235 steel surface was a spontaneous process and followed the Langmuir adsorption isotherm model.

Summary: In this study, an ethyl viologen-functionalized reduced graphene oxide composite (EV-RGO) was synthesized by one-step hydrothermal method. The ethyl viologen cations are anchored on the RGO sheets through different interactions, making EV-RGO more stable and reversible as an electrode material. The presence of viologen cations with ethyl groups effectively suppresses the stacking of RGO sheets and expands their interlayer spacing. In an ethyl-methylimidazolium tetrafluoroborate ionic liquid electrolyte, the electrochemical performance of EV-RGO is enhanced due to the synergistic contributions of electric double-layer capacitance and pseudocapacitance. The specific capacitance of EV-RGO as a negative electrode material for supercapacitors reaches 222.7 F g(-1) at a current density of 0.5 A g(-1). An asymmetric supercapacitor device (EVRGO//AC ASC) exhibits an energy density of 64.1 Wh kg(-1) at a power density of 888 W kg(-1). This work offers an advanced strategy for fabricating high-performance supercapacitors using organic molecule-modified graphene composites.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
