In this study, fresh harvested high moisture wheat was placed in a simulated warehouse for ventilation drying experiment, and the moisture content change in each layer of the wheat grain pile, the wheat crude protein, wet gluten content, flour properties, falling value, etc. were measured. The results showed that the longitudinal ventilation technology could reduce the wheat moisture content to safe moisture content in a short time for the wheat with moisture content more than 20% in the simulated warehouse, and had no significant adverse effect on the processing quality of wheat. The use of ventilation technology not only reduced the wheat moisture content effectively, but also restrained the deterioration of high moisture wheat quality, providing a theoretical basis for the actual warehouse drying of high moisture wheat.

The complexation behaviors of pagoda[n]arenes (n = 4, 5) with ferrocene, ferrocenium and analogues cobaltocenium were studied. The inclusion complexes of pagoda[n]arenes can protect ferrocenium from oxidation in organic solvents and improve the stability and oxygen resistance of ferrocenium. [ABSTRACT FROM AUTHOR]

Light harvesting is one of the fundamental steps in photosynthesis, and developing artificial light harvesting systems (LHSs) with high energy transfer efficiency is still a challenging task. Herein, we designed and constructed a novel fluorescent tetragonal Pd(II)-metallacycle (DDPH-Pd) as a new platform for the construction of artificial LHSs. 6,15-bis(pyridine)-9,12-bis(dodecyloxy)-substituted benzo[5]helicene (DDPH) and ethylenediamine palladium nitrate were coordinated to generate self-assembled DDPH-Pd. Carmosine and Nile red were chosen as acceptors due to their good spectral overlap with that of DDPH-Pd , which is essential for fabricating light-harvesting system. The artificial LHSs show good energy transfer efficiency (61%) and antenna efficiency (5.0) in Carmosine@ DDPH-Pd with a 50:1 donor/acceptor ratio. [Display omitted] • The new fluorescent metallacycles is assembled by the bipyridine ligand DDPH and ethylene-diamine palladium nitrate. • Amphipathic metallacycles further aggregate in water to form nano spheres. • The Pd(II)-metallacycles are used as a new platform for the construction of artificial light harvesting systems. • LHSs have good energy transfer efficiency (61%) and antenna efficiency (5.0) with donor/acceptor ratio of 50:1.
