A simplified prototype device of high-performance all-solid-state supercapacitors (ASSSs) based on 3D nitrogen and boron co-doped monolithic graphene aerogels (BN-GAs) is demonstrated for the first time. The resulting ASSSs show high specific capacitance, good rate capability, enhanced energy density or power density.

The high cost of platinum-based electrocatalysts for the oxygen reduction reaction (ORR) has hindered practical application fuel cells. Thanks to its unique chemical and structural properties, nitrogen-doped graphene (NG) is among most promising metal-free catalysts replacing platinum. In this work, we have developed a cost-effective synthesis NG by using cyanamide as nitrogen source oxide precursor, which led controllable contents (4.0% 12.0%) after pyrolysis. thermally treated at 900 °C...

DGAT1 encodes diacylglycerol O -acyltransferase (EC 2.3.1.20 ), a microsomal enzyme that catalyzes the final step of triglyceride synthesis. It became functional candidate gene for lactation traits after studies indicated mice lacking both copies are completely devoid milk secretion, most likely because deficient synthesis in mammary gland. Our mapping placed close to region quantitative trait locus (QTL) on bovine chromosome 14 variation fat content milk. Sequencing from pooled DNA revealed...
Highly uniform, ultrathin, layer-by-layer heteroatom (N, B) co-doped graphene films are fabricated for high-performance on-chip planar micro-supercapacitors with an ultrahigh volumetric capacitance of ∼488 F cm−3 and excellent rate capability due to the synergistic effect nitrogen boron co-doping.

Abstract Plant seeds prepare for germination already during seed maturation. We performed a detailed transcriptome analysis of barley (Hordeum vulgare) grain maturation, desiccation, and in two tissue fractions (starchy endosperm/aleurone embryo/scutellum) using the Affymetrix Barley1 GeneChip. To aid data evaluation, Arabidopsis thaliana MapMan PageMan tools were adapted to barley. The analyses allow number conclusions: (1) Cluster revealed smooth transition transcription programs between...

The highest molecular mass polypropylene, best isotacticity, and activity all are provided by 1, R1 = R3 CH3, R2 i-C3,H7. Hydrogenation six-membered ring drastically lowers obtained.
Various QTL mapping experiments led to the detection of a in centromeric region cattle chromosome 14 that had major effect on fat content milk. Recently, gene encoding diacylglycerol O-acyltransferase (DGAT1) was proposed be positional and functional candidate for this trait. This study investigated effects nonconservative lysine alanine (K232A) substitution DGAT1, which very likely represents causal mutation, milk production traits.

Recent work has mapped a quantitative trait locus (QTL) with effect on to the centromeric region bovine chromosome 14, gene encoding thyroglobulin ( TG ) being proposed positional and functional candidate for this QTL. Recently, diacylglycerol O ‐acyltransferase DGAT1) , which been within QTL, demonstrated affect content milk. In present study, effects 5′‐polymorphism...
Abstract The coordination compounds of the tridentate oligopyridine ligand 2,2′:6′,2′′‐terpyridine (tpy) are utilized in very different fields research, such as materials science (e.g. photovoltaics), biomedicinal chemistry DNA intercalation), and organometallic catalysis. Applications latter area have arisen from initial reports on electro‐ or photochemical processes and, today, a broad range reactions—from artificial photosynthesis (water splitting) to biochemical organic transformations...

Abstract 2,2′:6′,2′′‐Terpyridine (tpy) and its derivatives represent highly versatile ligands for the complexation of transition metal ions. Today, such complexes are employed in a diverse fashion – including inter alia materials science, opto‐electronics, pharmacy or catalysis. Concerning latter one, vast development has led to new improved applications both “conventional” organic chemistry ( i. e ., catalysis functional‐group interconversions, CH‐activation cross‐coupling reactions) as...
Defect-free graphene is impermeable to gases and liquids but highly permeable thermal protons. Atomic-scale defects such as vacancies, grain boundaries, Stone-Wales are predicted enhance graphene's proton permeability may even allow small ions through, whereas larger species gas molecules should remain blocked. These expectations have so far remained untested in experiment. Here, we show that atomically thin carbon films with a high density of atomic-scale continue blocking all molecular...
Abstract A quantitative trait locus (QTL) for milk fat percentage has been mapped consistently to the centromeric region of bovine chromosome 14 (BTA14). Two independent studies have identified nonconservative mutation K232A in acylCoA-diacylglycerol-acyltransferase 1 (DGAT1) gene as likely be causal observed variation. Here we provide evidence additional genetic variability at same QTL that is associated with variation within German Holstein population. Namely, show alleles DGAT1 promoter...
