Abstract As a remarkable class of plasmonic materials, two dimensional (2D) semiconductor compounds have attracted attention owing to their controlled manipulation plasmon resonances in the visible light spectrum, which outperforms conventional noble metals. However, tuning for 2D semiconductors remains challenging. Herein, we design novel method obtain amorphous molybdenum oxide (MoO 3 ) nanosheets, it combines oxidation MoS 2 and subsequent supercritical CO ‐treatment, is crucial step...
Abstract We report the application of a new conformation searching algorithm called simulated annealing to location global miniumum energy peptides. Simulated is Metropolis Monte Carlo approach generation in which both and temperature dependence Boltzmann distribution guides search for minimum. Both uphill downhill moves are possible, allows molecule escape from local minima. Applications 20 natural amino acid “dipeptide models” as well polyalanines up Ala 80 very successful finding lowest...
Treatment with Adriamycin (ADR) is one of the major causes chemotherapy‐induced cardiotoxicity and therefore principal limiting factor in effectiveness chemotherapy for cancer patients. Apigenin (API) has been shown to play a cardioprotective role. The present study examined effect API on ADR‐induced mice. Sixty male Kunming mice were randomly divided into 4 groups: control group, ADR model low‐dose treatment group (125 mg·kg −1 ), high‐dose (250 ). Blood samples taken evaluate spectrum...
Abstract We describe in this article our solution to the global minimum problem which uses simulated annealing algorithm of Kirkpatrick. This method is a Metropolis ( e ‐Δ E / kT ) Monte Carlo sampling conformation space with simultaneous constraint search by lowering temperature T so that converges on minimum. The Anneal‐Conformer program has been extensively tested peptides and organic molecules using either Amber or MM2 force fields. A history file process allows reconstruction random...
Carbyne, a sp1-hybridized allotrope of carbon, is linear carbon chain with exceptional theoretically predicted properties that surpass those sp2-hybridized graphene and nanotubes (CNTs). However, the existence carbyne has been debated due to its instability caused by Peierls distortion, which limits practical development. The only successful synthesis achieved inside CNTs, resulting in form known as confined (CC). CC can be synthesized multiwalled limiting property-tuning capabilities inner...
Low-dimensional carbon allotropes belong to the most revolutionary materials of last decades. The latest materialization confined carbyne, a linear chain sp1-hybridized encapsulated inside small-diameter nanotube host, is one extraordinary nano-engineering example. Inspired by these hybrid structures, in this work, we demonstrate feasibility synthesize nitrogen-doped carbyne using azafullerene (C59N) molecules nanotubes ("peapods") as precursors for growth carbyne. Resonance Raman...
An in situ electron microscopy study is presented of adhesion interactions between single-walled carbon nanotubes (SWNTs) by mechanically peeling thin free-standing SWNT bundles using nanomanipulation techniques inside a high-resolution scanning microscope. The measurements clearly reveal the process delaminating one bundle from its originally bound controlled-displacement manner and capture deformation curvature delaminated during process. A theoretical model based on nonlinear elastica...
Recently the applications of 2D materials have been broadened by engineering their mechanical, electronic, and optical properties through either lateral or vertical hybridization. Here, successful design fabrication a novel triphasic material vertically stacking 2H‐/1T′‐molybdenum disulfide (MoS 2 ) heterostructures on graphene with assistance supercritical carbon dioxide is reported. This structure experimentally shown to significantly enhance photocurrent densities for hydrogen evolution...
Poly(cyclotriphosphazene-co-4,4′-sulfonyldiphenol) (PZS) nanotubes were evaluated as an efficient adsorbent for the removal of Rhodamine B (RhB), a cationic dye from aqueous solution. The as-synthesized (PZS nanotubes) characterized by scanning electron microscopy (SEM), transmission microscope (TEM), Fourier transform infrared spectroscopy (FTIR) and N2 adsorption/desorption isotherms. factors influencing adsorption efficiency capacity had been systematically studied. Results showed that...
Neuropeptide Y (NPY) receptors belong to the G-protein-coupled receptor (GPCR) superfamily and mediate several physiological responses, such as blood pressure, food intake, sedation memory retention. To understand interactions between NPY Y1 subtype its ligands, computer modeling was applied natural peptide agonist, a small molecule antagonist, BIBP3226. An agonist antagonist binding domain elucidated using mutagenesis data for well other GPCR families. The ligands which were investigated...
<title>Abstract</title> The resonant Raman response is due to electronic and vibrational excitations. Interestingly, the fingerprint of confined carbyne highly unconventional comes concomitant several new features which can neither be assigned hosting tube, nor linear carbon chain a.k.a carbyne. This identifies tube-chain system as a true hybrid structure in spectrum usually driven by strong modifications excitations via charge transfer. Surprisingly, we show that results from those two...

Polyyne is an sp-hybridized linear carbon chain (LCC) with alternating single and triple carbon–carbon bonds. very reactive; thus, its structure can be easily damaged through a cross-linking reaction between the molecules. The longer polyyne is, more unstable it becomes. Therefore, difficult to directly synthesize long polyynes in solvent. encapsulation of inside nanotubes not only stabilizes molecules avoid reactions, but also allows restriction occur solely at ends polyynes, resulting...
