A novel kind of BaFe 12 O 19 /Fe 3 C/CNTs composite was developed by the acetylene chemical vapor deposition process. The composites perform great improvement in the microwave absorbing properties compared with pure BaFe 12 O 19 ferrite in 2–18 GHz range.
Hydrogel nanofibers with high swelling ratio are prepared by electrospinning polyvinylpyrrolidone and poly(acrylic acid) blend followed by subsequent heat treatment.
An efficient surface enhanced Raman scattering (SERS) substrate of graphene-isolated Ag nanoparticle (G/AgNP) has been developed by using excimer laser to ablate the ordered pyrolytic graphite in high vacuum onto Ag nanoparticles.
In this paper, we reported a facile strategy to fabricate a PDMS film-coated Au nanoparticle monolayer film (Au MLF) composite substrate for improving SERS detection of aromatic molecules in water and in the atmosphere.
Ni 0.85 Se was in situ grown on Ni foam via a facile hydrothermal process as a high-performance electrode for supercapacitors.
The GaSe flake can enhance Raman signal and the effect decreases with its thickness.
Here we present an in-depth and comprehensive study of the effect of the geometry and morphology of nanoarray (NA) substrates on their surface-enhanced Raman scattering (SERS) performance. The high-quality SERS-active NA substrates of various unit shapes and pitches are assembled through electron beam lithography and…
A hierarchical porous CNTs@NCS@MnO 2 composite was synthesized by a facile in situ chemical polymerization coating method, followed by a hydrothermal process, which exhibits high asymmetric performance.
Single crystals and nanocrystals of polyoxometalate-based metal-organic coordination networks for heterogeneous catalytic desulfurization.
An experimental and modeling study of glass–crystal Si 10 As 15 Te 75 –Bi 0.4 Sb 1.6 Te 3 composites.
The highly-polymorphic, strongly-coloured 'ROY' system exhibits a yellow → orange → red piezochromic response under hydrostatic compression. The 'Y' (yellow) polymorph accommodates the effect of pressure via a wine-rack-type mechanism, made accessible by the conformational flexibility of the molecule, while retaining…
A Ag nanoparticle-modified ZnO NWs based UV detector displays an excellent performance in UV detection such as high responsivity and fast response time.
The zT of Yb 14 MnSb 11 is improved by the introduction of a light rare earth element, RE 3+ (RE = Pr, Sm) with partially filled f-levels. The carrier concentration is reduced upon substituting RE 3+ for Yb 2+ , adding one electron to the system and improving the zT values 30–40% over that of the pristine material.
A series of racemic 2-[(2′-(dimethylamino)binaphthyl-2-ylimino)methyl]-4-R2-6-R(1)-phenols (L1H–L6H) were reacted with 1 equiv. of Mg[N(SiMe3)2]2 or Zn[N(SiMe3)2]2 to provide three heteroleptic magnesium silylamido complexes [(L4–(6))MgN(SiMe3)2] (4a: R(1) = R(2) = cumyl; 5a: R(1) = CPh3, R(2) = Me; 6a: R(1) = CPh3, R…
Graphene-containing fibrous structures with a high level of affinity towards a polymer matrix solution have been proved to be promising for high performance macroscopic nanocomposite reinforcement purposes.
Zinc substituted magnesium ferrite nanomaterials Mg1−xZnxFe2O4 (x = 0, 0.1, 0.3, 0.5, 0.7) powders have been prepared by a sol‐gel autocombustion method. The lattice parameter increases with increase in Zn concentration, but average crystallite size tends to decrease by increasing the zinc content. SEM results indicat…
Indoor aquatic mesocosms were designed to mimic pond ecosystems contaminated by a continuous point-source discharge of cerium oxide nanoparticles (CeO 2 -NPs).
Two models for the prediction of corrosion inhibition efficiency of various pure surfactant and mixed surfactants in salt-containing solution are developed, compared, and validated. The two prediction models are based on a modified Langmuir adsorption (MLA) sub-model and a modified Quantitative Structure Activity Rela…
The inhibitive action of leaf extract of Gundelia tournefortii (G. tournefortii) on mild steel corrosion in 2.0 M HCl and 1.0 M H2SO4 solutions was studied using weight loss measurement, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The inhibition efficiency was found to inc…
Diffusion-a measure of dynamics, and entropy-a measure of disorder in the system are found to be intimately correlated in many systems, and the correlation is often strongly non-linear. We explore the origin of this complex dependence by studying diffusion of a point Brownian particle on a model potential energy surfa…
