lineolatus. It was found that adult bugs of both genders were significantly attracted to methyl salicylate. Taken together, our findings suggest that AlinOR59 plays a crucial role in the perception of floral scents in A. lineolatus and could be used as a potential target to design novel olfactory regulators for the management of bugs.Knowledge of the biochemical processes responsible for the release of phenolic acids (precursors of vinyl aromatics) during malting is important to find mitigation strategies for the toxicologically relevant styrene (formed from cinnamic acid) in wheat beer. Therefore, grain and malts of four barley and three wheat varieties were screened for the activities of various enzymes and the amounts of nonstarch polysaccharides (to which the phenolic acids are bound to a certain extent). During malting, a very strong degradation of β-glucan, synonymous to a depletion of the cell walls, was found, suggesting that a partial degradation of cell walls cannot have an effect on the release of phenolic acids. In barley malts, water-extractable arabinoxylan contents were between 0.59 and 0.79 g/100 g dm and in wheat malts between 0.93 and 1.51 g/100 g dm. Additionally, higher soluble ferulic acid contents in wheat wort compared to barley wort indicated that the degradation of nonstarch polysaccharides has an impact on the release of phenolic acids. For the feruloyl esterase, higher activities were found in malts of the barley varieties. However, this fact was not reflected by the free phenolic acid contents in those malts. Correlation coefficients between the protease activity and the feruloyl esterase, α- and β-amylase, and β-glucanase activities were proven to be insignificant, highlighting that the protease activity had no effect on the activities of these other enzymes.In this paper, 2 atom % Al-doped ZnO (AZO) was prepared by the co-precipitation method together with sparking plasma sintering (SPS) treatment. The as-synthesized AZO powders show the morphology of hollow hexagonal towers, which result in a high porosity of 50.6% in the bulk sample consolidated by SPS sintering at 400 °C, and the porosity decreases gradually with increasing sintering temperature up to 1000 °C. Positron annihilation measurements reveal that even after sintering at 1000 °C, there are still a considerable number of small pores. A high electrical conductivity of 3 × 105 S m-1 is achieved at room temperature for the AZO sample sintered at 1000 °C, while the absolute values of Seebeck coefficient keep at relatively high values between 59 and 144 μV K-1 in the measurement temperature range of 27-500 °C, leading to a high power factor of 3.4 × 10-3 W m-1 K-2. On the other hand, the pores in AZO act as strong phonon scattering centers, and an extremely low thermal conductivity of 1.5 W m-1 K-1 measured at room temperature is obtained for AZO sintered at 400 °C. Due to the residual pores in the 1000 °C-sintered sample, the thermal conductivity is still relatively low. As a result, a maximum ZT of 0.275 measured at 500 °C is obtained in this sample, which is the highest ZT reported for ZnO around this temperature.The fabrication of hybrid protein-Cu3(PO4)2 nanoflowers (NFs) via an intermediate toroidal structure is dramatically accelerated under shear using a vortex fluidic device (VFD), which possesses a rapidly rotating angled tube. As-prepared laccase NFs (LNFs) exhibit ≈1.8-fold increase in catalytic activity compared to free laccase under diffusion control, which is further enhanced by ≈ 2.9-fold for the catalysis under shear in the VFD. A new LNF immobilization platform, LNF@silica incorporated in a VFD tube, was subsequently developed by mixing the LNFs for 15 min with silica hydrogel resulting in gelation along the VFD tube surface. The resulting LNFs@silica coating is highly stable and reusable, which allows a dramatic 16-fold enhancement in catalytic rates relative to LNF@silica inside glass vials. Ultraviolet-visible spectroscopy-based real-time monitoring within the LNFs@silica-coated tube reveals good stability of the coating in continuous flow processing. The results demonstrate the utility of the VFD microfluidic platform, further highlighting its ability to control chemical and enzymatic processes.Currently, most of the hole transport layers (HTLs) of organic solar cells (OSCs) are unable to meet the requirements of printing preparation, which imposes restrictions on the commercial process of the OSCs severely. Here, we report a printable HTL, PCPDTK0.50H0.50-TT. The PM6Y6PC71BM device with PCPDTK0.50H0.50-TT as an HTL exhibits a power conversion efficiency (PCE) of 16.3% (with an area of 0.04 cm2). More importantly, the PCE of the device is up to 10.2%, with an area of 1.0 cm2 prepared by the wire-bar coating PCPDTK0.50H0.50-TT HTL, which is in favor of the printing fabrication of the OSCs. In view of the superiorities of the large-area printing and the impressive PCE, we believe that PCPDTK0.50H0.50-TT should be a potential HTL for industrial production of OSCs.Asian and American Vitis species possess a strong potential for crossbreeding programs, owing to their several resistance properties. Stilbenes are phenolic compounds present in grape berries and are well-known for their main role as phytoalexins and resistance to biotic stresses in plants. However, their identification and quantification in grape berries from wild Vitis remains unexplored. A mass spectrometry multiple reaction monitoring method combined with the analysis of pure standards allowed for the unambiguous characterization of 20 stilbenes in the grape berry skin extracts of nine native Vitis species and one cultivated Vitis vinifera species (cv. Cabernet Sauvignon). selleck products A main occurrence of monomeric (Z-piceid, E-piceid, E-isorhapontin, and E-astringin), dimeric (E-ε-viniferin, Z-ε-viniferin, and pallidol), and oligomeric (isohopeaphenol and r-viniferin) stilbenes was highlighted. Some stilbenes were clearly characterized for the first time in grape berries, such as the dimers ampelopsin A, E-vitisinol C, and parthenocissin A as well as the tetramers r2-viniferin and r-viniferin. Stilbene composition and content varied widely among several Vitis species and vintage years.
