2D Homologous Perovskites as Light-Absorbing Materials for Solar Cell Applications.

Journal of the American Chemical Society, 2015
We report on the fabrication and properties of the semiconducting 2D (CH3(CH2)3NH3)2(CH3NH3)(n-1)Pb(n)I(3n+1) (n = 1, 2, 3, and 4) perovskite thin films. The band gaps of the series decrease with increasing n values, from 2.24 eV (CH3(CH2)3NH3)2PbI4 (n =

Preparation and Functional Properties of Glycosylated Walnut Peptides with Different Molecular Masses [PDF]

Shipin Kexue, 2023
Three walnut peptides with different molecular masses were prepared from walnut meal protein by sequential enzymatic hydrolysis and ultrafiltration, and separately glycosylated with five sugars (glucose, sucrose, lactose, maltodextrin and dextran).

Nitrogenase and homologs [PDF]

JBIC Journal of Biological Inorganic Chemistry, 2014
Nitrogenase catalyzes biological nitrogen fixation, a key step in the global nitrogen cycle. Three homologous nitrogenases have been identified to date, along with several structural and/or functional homologs of this enzyme that are involved in nitrogenase assembly, bacteriochlorophyll biosynthesis and methanogenic process, respectively.

Optimal Haplotype Assembly from High-Throughput Mate-Pair Reads

, 2015
Humans have $23$ pairs of homologous chromosomes. The homologous pairs are almost identical pairs of chromosomes. For the most part, differences in homologous chromosome occur at certain documented positions called single nucleotide polymorphisms (SNPs).
