Summary: We synthesized a hexabenzoperihexacene (HBPH) with two incorporated octacene substructures, characterized by single-crystal X-ray analysis. The isomerization barrier of the (P,P)-/(P,M)-forms was estimated to be 38.4 kcal/mol, and resolution was achieved by chiral HPLC. The enantiomers exhibited opposite circular dichroism responses up to the near-infrared (NIR) region, with a high g(abs) value of 0.017 at 616 nm. HBPH demonstrated NIR emission with a maximum at 798 nm and an absolute PLQY of 41%. The excited-state photophysical properties of HBPH were investigated, revealing interesting rotational and/or conformational dynamics after excitation. These findings provide new insights into designing chiral nanographene with NIR optical properties for potential chiroptical applications.

Summary: This study used P K-edge X-ray absorption near edge structure (XANES) spectroscopy to identify and quantify the dominant P minerals in legacy phosphorus (P) soils. Four phosphate mineral groups were identified, and organic P in the form of phytic acid was also found. The different forms of P have different impacts on soluble P losses and crop uptake in soils.

Summary: This study analyzed soil samples from six sites along a climatic gradient on Hawaii to investigate the presence of dust-derived phosphorus-containing minerals. The research found evidence of apatite grains collocated with quartz in wettest soils, suggesting recent atmospheric deposition of dust particles carrying phosphorus. Additionally, backward trajectory modeling indicated that dust particles may have been transported to Hawaii from major global dust-loading areas in central Asia and northern Africa.

Summary: Mg1-xCoxAl2O4, Zn1-xCoxFe2O4, and CrxSbxTi1-2xO2 pigment series with varying chemical constitution were prepared and structurally confirmed. Valence band maximum and Raman signal area were used to represent electronic and phononic absorption, respectively. The behavior of electronic and phononic absorption in near-infrared reflectance was trivial for Mg1-xCoxAl2O4 and Zn1-xCoxFe2O4, but nontrivial for CrxSbxTi1-2xO2. In CrxSbxTi1-2xO2, electronic absorption dominated at low doping regime, while phononic absorption played a dominance role at high doping regime. This nontrivial scenario provides insights into the reflective mechanism and paves the way for improving solar reflective pigment with color tuning.

Summary: In this work, the local structure of layered Ga1-xInxSe alloys was studied using X-ray Absorption and Raman spectroscopy. The presence of Ga - In bonds in the alloys was demonstrated, with similar cation-anion bond lengths to those of pure compounds and no significant increase in static disorder. The Raman spectra showed similar features to pure compounds, but with continuous peak shifting as impurity cations were introduced.

Summary: Mid-infrared dielectric metasurfaces offer potential for integrated sensing with high sensitivity, compositional selectivity, and low loss. A silicon metasurface with resonance properties in the mid-infrared region and a volume enhancement of up to 9 times was designed and fabricated. The detection limit of solutions of tungsten hexacarbonyl molecules was found to be 1 mg/mL without surface enrichment treatment. Volume field enhancement analysis rationalized the detection limit at the molecule-nanostructure interface. The results suggest that mid-infrared silicon metasurfaces may be suitable for integration with microfluidic devices for in vivo detection.

Summary: There is an ongoing debate in Europe regarding the criticality of phosphorus, with Switzerland and Germany requiring phosphorus recovery from phosphorus-rich waste streams. Thermochemical treatment of sewage sludge ash has shown to remove heavy metals and produce plant-available CaNaPO4. Upscaling of the process was successful, but differences were noticed in phosphorus solubility and crystal phases between pilot-scale and laboratory-scale experiments. Heavy metal removal increased at higher temperatures, while phosphorus solubility peaked at 950 degrees C in pilot-scale and 875 degrees C in laboratory-scale experiments.

Summary: Fluorine K-edge X-ray absorption near-edge structure (XANES) spectroscopy was used for the first time to detect per- and polyfluoroalkyl substances (PFAS) in soils and sewage sludges, offering the ability to differentiate between inorganic and organic fluorides without sample pre-treatment. While direct detection of targeted PFAS in bulk-XANES spectroscopy was not feasible in low concentration samples, direct analysis of pure PFAS showed promise for analyzing organofluorine species in more concentrated samples. Additionally, combustion ion chromatography (CIC) measurements emphasized that sewage sludges are a significant source of organic fluorine in agriculture.

Summary: Voltammetric and in situ infrared (IR) spectroelectrochemical studies were conducted to investigate the electrochemical dynamics of a stable trioxotriangulene (TOT) organic neutral pi- radical on a graphite electrode surface. The formation and dissolution of upright columnar crystals (face-on alignment) of TOT neutral radical were observed in a low concentration electrolyte, while more flat-lying columnar crystals (edge-on alignment) were formed in a higher concentration electrolyte. In situ IR attenuated total reflectance spectroscopy analyses characterized the crystal alignment and electrochemical behaviors of TOT neutral radicals, shedding light on the irreversible redox reaction of TOT on the graphite electrode.
