Titanate Nanotubes Decorated Graphene Oxide Nanocomposites: Preparation, Flame Retardancy, and Photodegradation

Most polymers exhibit high flammability and poor degradability, which restrict their applications and causes serious environmental problem like “white pollution.” Thus, titanate nanotubes (TNTs) were adopted to decorate graphene oxide (GO) by a facile solution method to afford TNTs/GO nanocomposites with potential in improving the flame retardancy and photodegradability of flexible ...

Preparation of Alumina Nanorods from Chromium-Containing Alumina Sludge

Alumina nanorods were prepared from chromium-containing alumina sludge, and the effects of doping elements, such as Cr, Fe, and Mg, were researched. The results show that the crystal transformation of alumina is restricted by the doped Cr and facilitated by the doped Fe and Mg, which is transformed from θ-Al2O3 to α-Al2O3 in the calcination process. Meanwhile, the crystal ...

Does salt stress affect the interspecific interaction between regionally dominant Suaeda salsa and Scirpus planiculumis?

Plant-plant interactions that change along environmental gradients can be affected by different combinations of environmental characteristics, such as the species and planting density ratios. Suaeda salsa and Scirpus planiculumis are regionally dominant species in the Shuangtai estuarine wetland. Compared with non-clonal S. salsa, clonal S. planiculumis has competitive advantages ...

Higher spins and Yangian symmetries

The relation between the bosonic higher spin \( {\mathcal{W}}_{\infty}\left[\lambda \right] \) algebra, the affine Yangian of \( \mathfrak{g}{\mathfrak{l}}_1 \), and the SHc algebra is established in detail. For generic λ we find explicit expressions for the low-lying \( {\mathcal{W}}_{\infty}\left[\lambda \right] \) modes in terms of the affine Yangian generators, and deduce from ...

De novo transcriptomic analysis and development of EST-SSRs for Sorbus pohuashanensis (Hance) Hedl.

Sorbus pohuashanensis is a native tree species of northern China that is used for a variety of ecological purposes. The species is often grown as an ornamental landscape tree because of its beautiful form, silver flowers in early summer, attractive pinnate leaves in summer, and red leaves and fruits in autumn. However, development and further utilization of the species are hindered ...

Forced oscillation for solutions of boundary value problems of fractional partial difference equations

In this paper, we obtain the forced oscillation of solutions for certain fractional partial difference equations with two different types of boundary conditions. Our results are based on discrete Gaussian formula and some basic theories of discrete fractional calculus. MSC: 26A33, 39A21, 39A14, 39A12.

Applications of the generalised Dirichlet integral inequality to the Neumann problem with fast-growing continuous data

By using the generalised Dirichlet integral inequality with continuous functions on the boundary of the upper half-space, we prove new types of solutions for the Neumann problem with fast-growing continuous data on the boundary. Given any harmonic function with its negative part satisfying similarly fast-growing conditions, we obtain weaker boundary integral condition.

Design of High Performance Si/SiGe Heterojunction Tunneling FETs with a T-Shaped Gate

In this paper, a new Si/SiGe heterojunction tunneling field-effect transistor with a T-shaped gate (HTG-TFET) is proposed and investigated by Silvaco-Atlas simulation. The two source regions of the HTG-TFET are placed on both sides of the gate to increase the tunneling area. The T-shaped gate is designed to overlap with N+ pockets in both the lateral and vertical directions, which ...

BPS spectrum on AdS3×S3×S3×S1

The BPS spectrum of string theory on AdS3 × S3 × S3 × S1 is determined using a world-sheet description in terms of WZW models. It is found that the theory only has BPS states with j + = j − where j ± refer to the spins of the \( \mathfrak{s}\mathfrak{u}(2) \) algebras of the large \( \mathcal{N} \) = 4 superconformal algebra. We then re-examine the BPS spectrum of the corresponding ...

Directing nucleation and growth kinetics in solution-processed hybrid perovskite thin-films

A heightened understanding of nucleation and growth mechanisms is paramount if effective solution processing of organic-inorganic perovskite thin-films for optoelectronic applications is to be achieved. Many fabrication techniques have been utilized previously to develop high-performance perovskite layers but there remains an absence of a unifying model that describes accurately ...

Computational explanation for bioactivation mechanism of targeted anticancer agents mediated by cytochrome P450s: A case of Erlotinib

EGFR inhibitors, even with therapeutics superiorities in anticancer, can cause idiosyncratic pulmonary and hepatic toxicities that are associated with the reactive electrophile bioactivated by Cytochrome P450s (P450s). Until now, neither has the electrophilic intermediate been caught experimentally, nor has the subtle mechanism been declared. Herein, the underlying mechanism of ...

Heterologous expression and characterization of a 3-ketosteroid-∆1-dehydrogenase from Gordonia neofelifaecis and its utilization in the bioconversion of androst-4,9(11)-dien-3,17-dione

3-Ketosteroid-∆1-dehydrogenase (KstD), a key enzyme in microbial steroid catabolism, catalyzes the trans-axial elimination of the C1 and C2 hydrogen atoms of the A-ring from the polycyclic ring structure of 3-ketosteroids, and it was usually used to transform androst-4-ene-3,17-dione (AD) to produce androsta-1,4-diene-3,17-dione. Here, the KstD from Gordonia neofelifaecis was ...

Oscillation results for certain forced fractional difference equations with damping term

In this paper, we establish two sufficient conditions for the oscillation of forced fractional difference equations with damping term of the form ( 1 + p ( t ) ) Δ ( Δ α x ( t ) ) + p ( t ) Δ α x ( t ) + f ( t , x ( t ) ) = g ( t ) , t ∈ N 0 , with initial condition Δ α − 1 x ( t ) | t = 0 = x 0 , where 0 < α < 1 is a constant, Δ α x is the Riemann-Liouville fractional difference ...

Exposure to atheroma-relevant 7-oxysterols causes proteomic alterations in cell death, cellular longevity, and lipid metabolism in THP-1 macrophages

The 7-oxysterols are recognised as strong enhancers of inflammatory processes in foamy macrophages. Atheroma-relevant 7-oxysterol mixtures induce a mixed type of cell death in macrophages, and trigger cellular oxidative stress responses, which mimic oxidative exposures observed in atherosclerotic lesions. However, the macrophage proteome has not previously been determined in the ...

Yellow-Leaf 1 encodes a magnesium-protoporphyrin IX monomethyl ester cyclase, involved in chlorophyll biosynthesis in rice (Oryza sativa L.)

Magnesium-protoporphyrin IX monomethyl ester cyclase (MPEC) catalyzes the conversion of MPME to divinyl protochlorophyllide (DVpchlide). This is an essential enzyme during chlorophyll (Chl) biosynthesis but details of its function in rice are still lacking. Here, we identified a novel rice mutant yellow-leaf 1 (yl-1), which showed decreased Chl accumulation, abnormal chloroplast ...

Background The prognostic value of neutrophil-lymphocyte ratio (NLR) and Glasgow Prognostic Score (GPS) has been extensively validated in various cancers. We aimed to examine the usefulness of a combination of NLR and GPS (named CNG) for predicting survival outcomes in patients after curative resection for gastric cancer (GC). Methods We retrospectively analyzed the records of 1056 ...
