Amyloid-Like Protein-Modified Carbon Nitride as a Bioinspired Material for Enhanced Photocatalytic CO Reduction.

Modification of g-CN with metal-free biomaterials through an environmentally friendly, low-energy, facile, and rapid single-step method is desired for the preparation of photocatalysts with efficient activity and high selectivity of CO reduction but remains a great challenge. Herein, we develop a phase-transitioned protein modification strategy for photocatalysts through superfast amyloid-like protein assembly on surfaces using a one-step sequential coating method. Metal-free carbon nitride/protein heterojunction composite photocatalysts (the phase-transitioned lysozyme (PTL), phase-transitioned bovine serum albumin (PTB), and phase-transitioned ovalbumin (PTO)-coated carbon nitride@SiO (CN@SiO) and bioinspired carbon nitride hollow nanospheres (CN-HS) obtained by etching of CN@SiO) are prepared using lysozyme, bovine serum albumin, and ovalbumin.

Simultaneous Loading of Ni P Cocatalysts on the Inner and Outer Surfaces of Mesopores P-Doped Carbon Nitride Hollow Spheres for Enhanced Photocatalytic Water-Splitting Activity.

Promoting charge separation, constructing active sites, and improving the utilization of metal atoms are very important for the design of efficient photocatalysts. A simultaneous loading of Ni P cocatalysts on the inner and outer surfaces of mesoporous P-doped carbon nitride hollow nanospheres (PCNHS) to construct a Ni P@PCNHS@Ni P photocatalyst is reported. Ni P cocatalysts loading provides enough active sites on both the inner and outer surfaces for proton reduction, and the formed heterojunctions simultaneously promote the migration and separation of the photogenerated charges on the inner and outer surfaces.

Screening for Autism Spectrum Disorder in Toddlers During the 18- and 24-Month Well-Child Visits.

Objective: Early screening contributes to the early detection of children with autism spectrum disorder (ASD). We conducted a longitudinal ASD screening study in a large community setting. The study was designed to investigate the diagnostic rate of ASD screening and determine the effectiveness of ASD screening model in a community-based sample.

Associations of early nutrition with growth and body composition in very preterm infants: a prospective cohort study.

Background/objective: To investigate impacts of early postnatal macronutrient intakes on growth and body composition of preterm infants within the first 6 months.

Subjects/methods: One hundred and thirty-three very preterm (VPT) and/or very low birth weight (VLBW) infants were consecutively included. Enteral and parenteral macronutrient intakes during the first 28 days were recorded and average daily intakes were calculated.
