Lutein production from microalgae: A review.

Lutein production from microalgae is a sustainable and economical strategy to offer the increasing global demands, but is still challenged with low lutein content at the high-cell density for commercial production. This review summarizes the suitable conditions for cell growth and lutein accumulation, and presents recent cultivation strategies to further improve lutein productivity. Light and nitrogen play critical roles in lutein biosynthesis that lead to the efficient multi-stage cultivation by increasing lutein content at the later stage.

Metallic-Bonded Pt-Co for Atomically Dispersed Pt in the CoN Matrix as an Efficient Electrocatalyst for Hydrogen Generation.

Exploiting highly efficient electrocatalysts toward hydrogen evolution reaction (HER) has a significant role in the mass production of hydrogen energy through water electrolysis. Herein, ginkgo leaf-like CoN coupled with trace Pt with metallic bond Pt-Co on nickel foam via solvothermal, tannic acid treated, and nitridation procedures for HER (T-Pt-CoN) is developed. It only requires low overpotentials of 31 mV and 27 mV to achieve 10 mA cm in alkaline and neutral electrolytes, respectively, surpassing the benchmark Pt/C and previously reported values.

Hollow-structured amorphous Cu(OH) nanowires doped with Ru for wide pH electrocatalytic hydrogen production.

Developing efficient and stable catalysts for electrocatalytic hydrogen evolution reaction (HER) with low overpotential is the key point to realizing large-scale hydrogen commercialization. Herein, Ru doped amorphous hollow copper hydroxide nanowires on copper foam (Ru-Cu(OH)/CF) is prepared by surface chemical oxidization and following solvothermal process. The hollow 3D nanowire structure can provide abundant accessibility active sites, promote electrolyte in filtration and facilitate gas diffusion in the process of the electrochemical reaction.

Two new inorganic-organic hybrid zinc phosphites and their derived ZnO/ZnS heterostructure for efficient photocatalytic hydrogen production.

Two novel inorganic-organic hybrid zinc phosphites, namely, [Zn(1,2-bimb)(HPO)] (1) and [Zn(1,4-bmimb)(HPO)] (2), (1,2-bimb = 1,2-bis(imidazol-1ylmethyl)benzene; 1,4-bmimb = 1,4-bis((2-methyl-1-imidazol-1yl)methyl)benzene) were synthesized for the first time by hydrothermal reaction. Compound 1 generates a three-dimensional (3D) pillared-layer structure with a 2-nodal 3,4-connected topology. While compound 2 exhibits a 2D hybrid zinc phosphite sheet with a 3,4-connected topology network.

Storage carbon metabolism of Isochrysis zhangjiangensis under different light intensities and its application for co-production of fucoxanthin and stearidonic acid.

This study explored the co-production of fucoxanthin and stearidonic acid from Isochrysis zhangjiangensis by investigating its carbon metabolism under different light intensities. Results showed high light inhibited the synthesis of fucoxanthin and stearidonic acid, while promoted cell growth and enhanced cellular lipid content compared with low light, achieving 2.4 g/L and 28.

Surfactant-free microemulsions of 1-butyl-3-methylimidazolium hexafluorophosphate, propylamine nitrate, and water.

Generally, surfactants (or amphiphiles) are believed to be necessary components of microemulsions. However, it has been demonstrated that, in the absence of traditional surfactants, microemulsions can also form from a ternary system of two immiscible fluids (i.e.
