The structural feature except for the split distribution of Bi3+/Na+ was classified as a Na2MnCl4-type structure. DFT calculations based on a model discounting the split distribution of Bi3+/Na+ indicated that Bi 6s and O 2p orbitals form sp hybridization at the conduction band. This new mixed valence bismuth oxide exhibited photocatalytic activity for phenol degradation under visible light irradiation. In addition to Na3Bi3O8, the hydrothermal reaction using NaBiO3·nH2O in NaOH solution yielded micrometer-sized single crystals of an ilmenite-type NaBiO3 and two polymorphs of bismuth oxides with monoclinic (α-Bi2O3) and orthorhombic (ε-Bi2O3) structures, depending on the reaction temperature and NaOH concentration.This analysis investigates the cost of carbon capture from the US natural gas-fired electricity generating fleet comparing two technologies Post-Combustion Capture and Direct Air Capture (DAC). Many of the existing Natural Gas Combined Cycle (NGCC) units are suitable for post-combustion capture. We estimated the cost of post-combustion retrofits and investigated the most important unit characteristics contributing to this cost. Units larger than 400 MW, younger than 14 years, more efficient than 45% and with a utilization (capacity factor) higher than 0.5 were found to be the most promising for retrofit. Counterintuitively, DAC (which is usually not considered for point-source capture) may be cheaper in addressing emissions from non-retrofittable NGCC units. DAC can also address the residual emissions from retrofitted units. Moreover, the economic challenges of post-combustion capture for small natural gas-fired units with low utilization, such as gas turbines, make DAC look favorable for these units. After considering the cost of post-combustion capture for the entire natural gas-related emissions and incorporating the impact of learning-by-doing for both carbon capture technologies, our results show that DAC is the cheaper capture solution for at least 1/3 of all emissions.This study reports the transcriptional activity of fin (Balaenoptera physalus) and blue whale (B musculus) peroxisome proliferator-activated receptor gamma (PPARG), glucocorticoid receptor (GR) and thyroid hormone receptor beta (THRB), when exposed to 14 legacy persistent organic pollutants (POPs) and a synthetic mixture of POPs, using GAL4-UAS based in vitro luciferase reporter gene assays. PCBs had both agonistic and antagonistic effects on PPARG and GR, and mainly antagonistic, except PCB153, effects on THRB. DDT and its metabolites had mainly antagonistic effects on all of the receptors, except for o,p´-DDT. Given that the ligand binding domain (LBD) of PPARG is the same in killer whales, white whales, polar bears and humans, and that GR-LBD is identical in killer whales and minke whales and the LBD of THRB is the same in killer whales, white whales and humans, it is likely that the results of this study are representative for these other species as well. It is important to note that several environmental pollutants modulated the transcriptional activity of tested nuclear receptors at environmentally relevant concentrations for whales.Separation of C8 alkyl-aromatics (o-xylene, m-xylene, and p-xylene) remains one of the most challenging tasks to date due to their similar physical and chemical properties. Cd2+- and Zn2+-based luminescent metal-organic frameworks (MOFs) have been synthesized for the selective identification of m-xylene in a pool of other isomers by fluorometric methods. Inhibition of the photoinduced electron transfer process is the prime reason for fluorescence enhancement, owing to the comparable molecular orbital energies for m-xylene in comparison with o- and p-xylene. Density functional theory calculations signify that the extraordinary selectivity is mainly due to the high dipole moment of m-xylene that might enhance the ring current, leading to a strong π-π interaction with the MOF's co-ligand. As a practical application, fluorometric sensing could be used for the estimation of m-xylene in different solvent media. Moreover, X-ray structural analysis reveals that the Zn2+-MOF can encapsulate m-xylene selectively within its framework among other constitutional isomers, which also emphasizes its capability for practical implementation.Microalgae are primary producers with multiple nutrients in aquatic environments and mostly have applications in biological feed and fuel industry. There are few studies assessing the angiotensin-I-converting enzyme (ACE) inhibition potential of Isochrysis zhanjiangensis, other than its antioxidant potential. In this study, we evaluated a peptide from I. zhanjiangensis (PIZ, FEIHCC) and its vascular endothelial factors and mechanism in human umbilical vein endothelial cells (HUVEC). The results reveal that PIZ (IC50 = 61.38 μM) acts against ACE in a non-competitive binding mode. In addition, PIZ inhibits angiotensin II (Ang II)-induced vascular factor secretion and expression by blocking inflammation and apoptosis through nuclear factor κB (NF-κB), nuclear erythroid 2-related factor 2 (Nrf2), mitogen-activated protein kinases (MAPKs), and the serine/threonine kinase (Akt) signal pathways. This study reveals that PIZ has potential to be developed as a therapeutic agent for hypertension and provides a new method of high-value utilization of I. selleck compound zhanjiangensis.Proteins with a functionalized C-terminus such as a C-terminal thioester are key to the synthesis of larger proteins via expressed protein ligation. They are usually made by recombinant fusion to intein. Although powerful, the intein fusion approach suffers from premature hydrolysis and low compatibility with denatured conditions. To totally bypass the involvement of an enzyme for expressed protein ligation, here we showed that a cysteine in a recombinant protein was chemically activated by a small molecule cyanylating reagent at its N-side amide for undergoing nucleophilic acyl substitution with amines including a number of l- and d-amino acids and hydrazine. The afforded protein hydrazides could be used further for expressed protein ligation. We demonstrated the versatility of this activated cysteine-directed protein ligation (ACPL) approach with the successful synthesis of ubiquitin conjugates, ubiquitin-like protein conjugates, histone H2A with a C-terminal posttranslational modification, RNase H that actively hydrolyzed RNA, and exenatide that is a commercial therapeutic peptide.
