Nanocomposites of and conductive carbon were prepared by two different methods which lead to enhanced electrochemical accessibility the Fe redox centers in this insulating material. Method A employs a composite phosphate with xerogel formed from resorcinol-formaldehyde precursor; method B uses surface-oxidized particles act as nucleating agent for growth. Both particle size minimization intimate contact are necessary optimize performance. Although both succeed first criteria, latter is best...
Impressive capacity improvements can be obtained by wrapping insulating crystallites of Li3V2(PO4)3 within a conductive carbon web. The single crystal analysis (see Figure) and electrochemical characteristics are reported. X-ray diffraction the phases formed on Li extraction shows that framework is maintained with little loss crystallinity; re-insertion Li, Li3.0V2(PO4)3 fully recrystallized.
DNA methylation is an important epigenetic mark involved in many biological processes. The genome of the climacteric tomato fruit undergoes a global loss due to active demethylation during ripening process. It unclear whether other fruits also associated with demethylation. We characterized single-base resolution methylomes sweet orange fruits. Compared immature fruits, ripe gained at over 30,000 genomic regions and lost about 1,000 regions, suggesting increase ripening. This was correlated...
Abstract A contribution of DNA methylation to defense against invading nucleic acids and maintenance genome integrity is uncontested; however, our understanding the extent involvement this epigenetic mark in genome-wide gene regulation plant developmental control incomplete. Here, we knock out all five known methyltransferases Arabidopsis , generating methylation-free plants. This quintuple mutant exhibits a suite defects, unequivocally demonstrating that essential for multiple aspects...
Element doping/substitution has been recognized as an effective strategy to enhance the structural stability of layered cathodes. However, abundant substitution studies not only lack a clear identification sites in material lattice, but rigid interpretation transition metal (TM)-O covalent theory is also sufficiently convincing, resulting proposals being dragged into design blindness. In this work, taking Li1.2Ni0.2Mn0.6O2 prototype, intense correlation between "disordered degree" (Li/Ni...
Demetalation, caused by the electrochemical dissolution of metal atoms, poses a significant challenge to practical application single-atom catalytic sites (SACSs) in proton exchange membrane-based energy technologies. One promising approach inhibit SACS demetalation is use metallic particles interact with SACSs. However, mechanism underlying this stabilization remains unclear. In study, we propose and validate unified which can Fe Metal act as electron donors, decreasing oxidation state...
Although Ru-based materials are among the outstanding catalysts for oxygen evolution reaction (OER), instability issue still haunts them and impedes widespread application. The of OER is generally ascribed to formation soluble species through over-oxidation Ru structural decomposition caused by involvement lattice oxygen. Herein, an effective strategy selectively activating around site proposed improve activity stability. Our synthesized spinel-type electrocatalyst Zn co-doped Co
Abstract In pursuing cheap and effective oxygen reduction catalysts, the Fe/N/C system emerges as a promising candidate. Nevertheless, structural transformations of starting materials into Fe- N-doped carbon catalysts remains poorly characterized under pyrolytic conditions. Here, we explore evolution Fe species track formation Fe–N 4 site development by employing diverse in-situ diagnostic techniques. In-situ heating microscopy reveals initial FeO x nanoparticles subsequent internal...

Drought stress is a major threat to crop production, but effective methods mitigate the adverse effects of drought are not available. Here, we report that adding fluorine atoms in benzyl ring abscisic acid (ABA) receptor agonist AM1 optimizes its binding ABA receptors by increasing number hydrogen bonds between compound and surrounding amino residues ligand-binding pocket. The new chemicals, known as AMFs, have long-lasting promoting stomatal closure inducing expression stress-responsive...
Abstract Epigenetic variation has been proposed to facilitate adaptation changing environments, but evidence that natural epialleles contribute adaptive evolution lacking. Here we identify a retrotransposon, named “NMR19” (naturally occurring DNA methylation region 19), whose and genomic location vary among Arabidopsis thaliana accessions. We classify NMR19 as NMR19-4 NMR19-16 based on its location, uncover an epiallele controls leaf senescence by regulating the expression of PHEOPHYTIN...
Active DNA demethylation is critical for controlling the methylomes in plants and mammals. However, little known about how demethylases are recruited to target loci, involvement of chromatin marks this process. Here, we identify 2 components SWR1 chromatin-remodeling complex, PIE1 ARP6, as required ROS1-mediated demethylation, discover SWR1-associated bromodomain-containing proteins, AtMBD9 nuclear protein X1 (NPX1). NPX1 recognize histone acetylation established by increased methylation 1...
Although organic artificial enzymes have been reported as biomimetic oxidation catalysts and are widely used for colorimetric biosensors, developing with high enzymatic activity is still a challenge. Two-dimensional (2D) covalent frameworks (COFs) shown superior potential in biocatalysts because of their periodic π-π arrays, tunable pore size structure, large surface area, thermal stability. The interconnection electron acceptor donor building blocks the 2D conjugated COF skeleton can lead...
Vigorously developing new stationary phases to meet the requirements for separation of positional isomers that have similar physicochemical properties is still an urgent topic in science. Herein, a single-crystalline covalent organic framework (COF-300) packed column high-performance liquid chromatography (HPLC) was reported first time. Benefitting from its regular shape, excellent chemical and thermal stability, microporous feature, strong hydrophobicity COF-300, COF-300-packed showed...

Replacement of expensive and rare platinum with metal-nitrogen-carbon catalysts for oxygen reduction reactions in proton exchange membrane fuel cells is hindered by their inferior activity. Herein, we report a highly active iron-nitrogen-carbon catalyst optimizing the carbon structure coordination environments Fe-N
Open-cage fullerenes can act as hosts for small molecules such water, nitrogen, or hydrogen, forming endohedral fullerenes. Following a brief summary of carbon, and oxygen insertion in the fullerene framework to form homofullerenes, methods creating hole surface are surveyed. Techniques enlargement atoms through orifice described. Finally, possibility subsequent closure is considered.
An electrically bistable and non-volatile rewritable memory effect on a sandwich architecture, ITO/PEDOT:PSS/organic–inorganic hybrid perovskite/Cu, is shown.
Significance The epigenome influences gene regulation and genome evolution. DNA methylomes of Arabidopisis hybrids are distinct from both parents; however, how the parental interact in is poorly understood. We discovered pervasive, nonadditive methylation changes (“methylation interactions”) throughout Col C24 Arabidopsis accessions. Methylation interactions correlated with high levels small interfering RNAs, known components RNA-directed (RdDM) pathway. Indeed, abrogation RdDM activity...
