For the 40 K superconductor ${\mathrm{MgB}}_{2},$ we have calculated electronic and phononic structures electron-phonon (e-ph) interaction throughout Brillouin zone ab initio. In contrast to isoelectronic graphite, ${\mathrm{MgB}}_{2}$ has holes in bonding \ensuremath{\sigma} bands, which contribute $42%$ density of states: $N(0)=0.355$ $\mathrm{states}/({\mathrm{MgB}}_{2})(\mathrm{eV})(\mathrm{spin}).$ The total strength, $\ensuremath{\lambda}=0.87$...
We report molecular dynamics simulations showing that a DNA molecule could be spontaneously inserted into carbon nanotube (CNT) in water solute environment. The van der Waals and hydrophobic forces were found to important for the insertion process, with former playing more dominant role DNA−CNT interaction. Our study suggests encapsulated CNT−DNA complex can further exploited applications such as modulated electronics, sensors, electronic sequencing, nanotechnology of gene delivery systems.
3D N-doped graphene crosslinked by covalent bonds is fabricated through thermal treatment of oxide with a nitrogen-contained resin. The material possesses hierarchical porous architecture, robust mechanical stability, and abundant properties. As an electrode for supercapacitors, this multifunctional exhibits unprecedented specific capacitance, high rate capability, excellent long-term cycle stability.
The development of highly active and durable inexpensive electrocatalysts for hydrogen evolution reaction (HER) is still a formidable challenge. Herein, an ordered hexagonal-closed-packed (hcp)-Ru nanocrystal coated with thin layer N-doped carbon (hcp-Ru@NC) was fabricated through the thermal annealing polydopamine (PDA)-coated Ru nanoparticle (RuNP@PDA). As alternative to Pt/C catalyst, hcp-Ru@NC nanocatalyst exhibited small overpotential 27.5 mV at current density 10 mA cm–2, as well...
▪ Abstract Carbon nanotubes functionalized with biological molecules (such as protein peptides and nucleic acids) show great potential for application in bioengineering nanotechnology. Fundamental understanding, description, regulation of such bio-nano-systems will ultimately lead to a new generation integrated systems that combine unique properties the carbon nanotube (CNT) recognition capabilities. In this review, we describe recent advances understanding interactions between...
Aniline was chemically bonded to the surface of graphene oxide (GO) via a nucleophilic ring-opening reaction. The aniline-bonded GO then reduced (RGO) in presence multi-walled carbon nanotubes (MWCNTs), which could prevent RGO from aggregating. aniline further responsible for grafting polyaniline (PANI) onto chemical oxidative polymerization aniline, and resultant PANI-RGO/MWCNT ternary nanocomposite be used as supercapacitor electrode with high performance.
Although several studies related with the electrochemiluminescence (ECL) technique have been reported for chiral discrimination, it still has to face some limitations, namely, complex synthetic pathways and a relatively low recognition efficiency. Herein, this study introduces facile strategy synthesis of ECL-active covalent organic frameworks (COFs) employed as platform. In artificial structure, ruthenium(II) coordinated dipyridyl unit COF enantiopure cyclohexane-1,2-diamine was harnessed...
Designing single-template molecularly imprinted chiral sensors for the enantioselective recognition of various amino acids (AAs) is great importance analysis. Here, a dummy template-based sensor developed by using l-alanine (l-Ala) as template and poly(o-phenylenediamine) imprinting layer, which can be used AAs such Ala, tryptophan (Trp), tyrosine (Tyr), cysteine (Cys), arginine (Arg). Compared with conventional sensors, designed shows universality since all possess an Ala-analogous segment....
The effects of single-walled carbon nanotubes on the polymerase chain reaction (PCR) were investigated via quantitative PCR product measurements, scanning electron microscopy (SEM), high-resolution transmission (TEM) and x-ray photoelectron spectroscopy (XPS). results showed that adding (SWCNTs) into liquid increases amount at SWCNT concentrations below 3 µg µl−1, but this effect is reversed higher concentrations. Similar observed in reactions with or without Mg2+. Both SEM HRTEM DNA...
Inspired by the double helix structure of DNA, a simple enantioselective system based on chitosan (CS) was employed for electrochemical enantiorecognition tryptophan (Trp) isomers. The recognition mechanism proposed from supramolecular point view, which further verified Trp isomers with sulfonated CS (SCS). SCS-based chiral presented ability indicating percentage d-Trp in racemic mixture, extending future applications natural polysaccharides.

Construction of convenient systems for isomer discrimination is great importance medical and life sciences. Here, we report a simple effective chiral sensing device based on highly ordered self-assembly framework. Cu2+-modified β-cyclodextrin (Cu-β-CD) was self-assembled to the ammonia-ethanol cotreated chitosan (ae-CS), framework gradually formed during "re-growth" process shrinked ae-CS films. Tryptophan (Trp) isomers were well discriminated with by electrochemical approach. This study...
We report a Cu2+-modified β-cyclodextrin, Cu2-β-CD, that was self-assembled on poly(l-glutamic acid) (P-l-Glu) for chiral recognition of d-tryptophan (d-Trp). Cu2+ formed binuclear hydroxy-bridge (Cu(OH)2Cu) at the wider opening cavity β-CD and acted as cap to prevent high-energy water molecules from being released while forcing Trp isomers enter through its narrower opening. Because H-bonds were favored form between amino groups d-Trp inside β-CD, thus recognized. The capability Cu2-β-CD...
The development of a highly active and exceedingly durable electrocatalyst at low cost for the oxygen reduction reaction (ORR) is extremely desirable but remains to be grand challenge. Over past decade, transitional-metal (e.g., Fe, Co, Ni) N codoped graphene materials have attracted most attention as state-of-the-art nonprecious-metal-based effective ORR still entail unsatisfactory issues such moderate activity life. Herein, main-group-metal Al (ANG) successfully fabricated via thermal...
