Summary: A novel composite material CQD-OTNs was synthesized and applied for the photo-degradation of TC, showing significantly enhanced degradation efficiency compared to pure titanium dioxide nanosheets. The improved photocatalytic activity of CQD-OTNs was attributed to the constructed oxygen enriched structure and CQDs, leading to the effective separation of electron-hole pairs and enhanced degradation of TC with generated hydroxyl and superoxide radicals.

Summary: The study reveals the microscopic mechanism behind the reduced reaction rate observed in cavity-induced resonant vibrational strong light-matter coupling using quantum-electrodynamical density-functional theory. The cavity mode acts as a mediator between different vibrational modes, redistributing vibrational energy and ultimately inhibiting the reaction.

Summary: In this study, a Ti3+/TNS(TiO2 nanosheet arrays)-CZTS (Cu2ZnSnS4) photocatalyst was designed and synthesized. The Ti3+ modification evenly distributed p-type CZTS nanoflowers on the surface of n-type TNS, forming a CZTS/TiO2 p-n heterostructure. The Ti3+/TNS-CZTS photocatalyst exhibited significantly better photocatalytic activity for methyl orange degradation compared to TNS, which can be attributed to the doping of Ti3+ and the synergistic effect of the CZTS/TiO2 p-n heterojunction.

Summary: Two multichromophoric FRET macrocycles M1 [1+1] and M2 [2+2] with red emission (lambda(em) similar to 721 nm) composed of perylenediimide (PDI) as the energy donor and aza-BODIPY (ABDP) as the energy acceptor were synthesized by click reaction in a metal-free fashion. M1 and M2 exhibited distinct reversible ratiometric temperature responsive emission with temperature sensitivities of 0.09-0.14% degrees C-1 and owing to the redox active chromophores, they showed solution phase redox responsive reversible colour changes.

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: This study synthesized Cs2NaInCl6 nanocrystals co-doped with Sb3+ and Tb3+ ions as probes for copper ions detection in lubricating oil. The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

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.
