An automatic feeder for poultry farm with digital display, adjustable temperature and humidity and timing function. It is mainly composed of feeding mechanism, feeding mechanism, travel mechanism, temperature humidity and electrical control box with digital display, can display 24 hours, and with time setting function, in the case of a single intervention to perform automatic feeding work, reduces the labor cost, not only can reduce the time of staff contact with poultry, reduce the spread of disease. With a temperature humidity sensor at the same time, the real-time monitoring and display of breeding field numerical, temperature and humidity can be set to allow upper and lower limits of temperature and humidity fluctuations, and according to the set point control spraying water pump, fan, or heating equipment synchronization work, simplifies the operation of separation equipment, precise control of the feeding environment of temperature and humidity value, achieve the goal of the poultry feeding scientifically.

Silica microspheres functionalized with 5-(4-allyloxy)phenyl-10,15,20-tri(p-sulfonatophenyl)porphyrin (APTSPP), SiO2-S-APTSPP, have been synthesized and characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and ultraviolet–visible diffuse reflectance spectroscopy (DRS). The visible light photocatalytic activity of SiO2-S-APTSPP was demonstrated successfully for the photooxidation of 1,5-dihydroxynaphthalene (DHN) in water. Influencing factors such as amount of catalyst, pH value and the addition of NaN3 were studied in detail. This new heterogeneous catalyst is of high stability and reusability and can be reused several times without loss of its activity in the oxidation reactions.

On the basis of synthesis of styrene–hydroxyethyl methacrylate copolymer microspheres with a functionalized hydroxyl, we have prepared a new type of copolymer microspheres immobilized porphyrinatomanganese(III), P(St-co-HEMA)MnP, by a condensation reaction between a hydroxyl in copolymer microspheres surface and a carboxyl in porphyrin ring. The obtained copolymer catalyst (P(St-co-HMEA)MnP) was characterized by SEM, UV–vis, IR, ICP and TG–DTG. The SEM image shows that the morphology of the copolymer catalyst is spheriform with ca. 4 μm diameter. The catalytic activity of P(St-co-HMEA)MnP to epoxidize cyclohexene in the presence of molecular oxygen and isobutylaldehyde has been studied. The catalytic efficiency of P(St-co-HMEA)MnP is comparable to that of non-supported MnCMPTTP. It is a mild, reusable and highly efficient heterogeneous catalyst for the epoxidation of cyclohexene.

The photodegradation of 1,5-dihydroxynaphthalene catalyzed by meso-tetra(4-sulfonatophenyl)porphyrin (H2TPPS4−) under visible light irradiation in aerated aqueous solution has been studied and the main product has been identified as 5-hydroxy-1,4-naphthoquinone. It is found that the photodegradation is dependent on the pH of reaction system and the addition of sodium azide (NaN3) leads to a significant decrease in the degree of 1,5-dihydroxynaphthalene photodegradation. The species distribution of H2TPPS4− in solution was obtained from potentiometric titration experiments. It is suggested that the mono-protonated monomeric species [H(H2TPPS)]3− is the main active species of H2TPPS4− to catalyze 1,5-dihydroxynaphthalene photodegradation.

The density functional theory (DFT) is used to calculate magnetic coupling constants and electronic absorption spectra of binuclear copper (II) complexes. The calculated results show that the increase in electronegativity of the terminal ligands can weaken the antiferromagnetic interaction, and can make the maximum absorption wavelength red-shift. In addition, the influence of conjugate structure between magnetic center and bridging atom on magnetic coupling interactions and electronic absorption spectra has also been analyzed. The calculated results may be useful as theoretical references for synthesis of the new functional complex and the molecular assembly analysis.
