From field harvest to the consumer’s table, fresh citrus fruit spends a considerable amount of time in shipment and storage. During these processes, physiological disorders and pathological diseases are the main causes of fruit loss. Heat treatment (HT) has been widely used to maintain fruit quality during postharvest storage; however, limited molecular(More)
Citric acid plays an important role in fresh fruit flavor and its adaptability to post-harvest storage conditions. In order to explore organic acid regulatory mechanisms in post-harvest citrus fruit, systematic biological analyses were conducted on stored Hirado Buntan Pummelo (HBP; Citrus grandis) fruits. High-performance capillary electrophoresis,(More)
Recently we demonstrated oriented formation of gold nanoparticle (AuNP) dimers for ultrasensitive sensing oligonucleotides (J. Am. Chem. Soc. 2013, 135, 12338). Herein, we investigate the reverse process of this sensing mechanism using target analytes to disassemble the orient-aggregated AuNP dimers. This enables us to expand the analytes from(More)
Citrus (Citrus spp.), a nonclimacteric fruit, is one of the most important fruit crops in global fruit industry. However, the biological behavior of citrus fruit ripening and postharvest senescence remains unclear. To better understand the senescence process of citrus fruit, we analyzed data sets from commercial microarrays, gas chromatography-mass(More)
Based on investigating growth characteristic of bayberry, harvest manipulator was developed in this paper. Single-mast rising mechanism, driven by hydraulics cylinder is used in the manipulator frame structure. Rods with irregular section in rising mechanism, material of which is 2A12, have great intensity and stiffness. Drive between rods is transmitted by(More)
With assistance of reactive and coordinative hydrazine, transition-metal telluromercurates [Mn(trien)(N2H4)2]2[Hg2Te4]2 (A), [Zn(trien)(N2H4)2]Hg2Te4 (B), [Mn(tepa)(N2H4)]2Hg4Te12 (C), [TM(trien)(Hg2Te4)] (TM = Mn (D), Zn (E)), and [Zn(atep)]2Hg5Te12 (atep = 4-(2-aminoethyl)triethylenetetramine) (F) were solvothermally prepared in triethylenetetramine(More)
The preparative-scale separation of chiral compounds is vitally important for the pharmaceutical industry and related fields. Herein we report a simple approach for rapid preparative separation of enantiomers using functional nucleic acids modified gold nanoparticles (AuNPs). The separation of DL-tryptophan (DL-Trp) is demonstrated as an example to show the(More)
