Abstract We present a simple analytical model to estimate the magnetization ( σ s ) and intrinsic coercivity ( H ci ) of a hard/soft nanocomposite magnet using the mass fraction. Previously proposed models are based on the volume fraction of the hard phase of the composite. However, it is difficult to measure the volu…
We present a systematic study on the adsorption properties of molecular oxygen on Pt, Ni and PtNi clusters previously deposited on MgO(100) by means of density functional theory calculations. We map the different adsorption sites for a variety of cluster geometries, including icosahedra, decahedra, truncated octahedra…
Abstract Ideally hexagonally ordered TiO 2 nanotube layers were produced through the optimized anodization of Ti substrates. The Ti substrates were firstly covered with a TiN protecting layer prepared through atomic layer deposition (ALD). Pre‐texturing of the TiN‐protected Ti substrate on an area of 20×20 μm 2 was ca…
An electro-optically switchable infrared filter based on guided-mode resonances in a zenithal-bistable liquid-crystal grating is designed and theoretically investigated. By proper selection of the material and geometrical parameters, it is shown that the grating can switch between transparent and narrowband filtering…
For martensitic transformations the macroscopic crystal strain is directly related to the corresponding structural rearrangement at the microscopic level. In situ optical microscopy observations of the interface migration and the change in crystal shape during a displacive single crystal to single crystal transformati…
A photochemical strategy for the sequential dual compaction of single polymer chains is introduced. Two photoreactive methacrylates, with side chains bearing either a phenacyl sulfide (PS) or an α‐methylbenzaldehyde (photoenol, PE) moiety, are selectively incorporated by one‐pot iterative reversible‐addition fragmenta…
The functions of some natural supramolecular architectures, such as ribosomes, are dependent on the recognition of different types of chiral biomolecules. However, the recognition of different types of chiral molecules (multiobject chiral recognition), such as amino acids and sugars, by independent and identically art…
A general 3-D internal charge analysis method, 3-D NUMIT, was developed by combining a Monte Carlo radiation transport simulation tool such as MCNPX or GEANT4 and a commercial finite-element analysis software such as COMSOL. The method was validated in 1-D cases with the analytical solution and NUMIT 2.0 and in a 3-D…
BACKGROUND: Nanomedicine offers a promising tool for therapies of brain diseases, but potential effects on neuronal health and neuronal differentiation need to be investigated to assess potential risks. The aim of this study was to investigate effects of silica-indocyanine green/poly (ε-caprolactone) nanoparticles (PC…
High‐resolution X‐ray photoelectron spectroscopy (XPS) of valence bands of vitreous silica (SiO 2 (vit)), and Na‐silicate glasses are divisible into 3 sub‐bands. These are the O 2s band, the lower valence band (LVB), and the upper valence band (UVB). Many peaks of the LVB and UVB have line widths (full width at half m…
Abstract Preparation of two‐dimensional (2D) heterostructures is important not only fundamentally, but also technologically for applications in electronics and optoelectronics. Herein, we report a facile colloidal method for the synthesis of WO n ‐WX 2 ( n =2.7, 2.9; X=S, Se) heterostructures by sulfurization or selen…
The Letter presents the results of characterisation of intercalated and exfoliated graphite. The electrochemically exfoliated graphite (EEG) was synthesised in solution containing sulphuric acid and potassium chlorate(V). The number of graphene layers, degree of disordering and the presence of functional groups were d…
Heteropolymers are important examples of self-assembling systems. However, in the design of artificial heteropolymers the control over the single chain self-assembling properties does not reach that of the natural bio-polymers, and in particular proteins. Here, we introduce a sufficiency criterion to identify polymers…
In the present study, five soil exoenzymes (dehydrogenase, urease, acid phosphatase, neutral phosphatase, and alkaline phosphatase) were investigated in rhizosphere of wetland plants (Iris wilsonii, Arundo donax, and Typha orientalis) treated with silver nanoparticles (0, 0.024, 0.24, 4.80, and 9.60 μg/g dry soil). It…
Abstract In this paper, we report the first hydrogenation kinetics of TiFe + X wt.% Zr with X = 4, 8, 12, and 16. We found that these alloys are multiphase with a TiFe matrix having about 1 at.% of zirconium in it and two secondary phases, which are rich in zirconium but also contain Ti and Fe. When X increases, the c…
Abstract Accurate prediction of the electronic and hydrogen storage properties of linear carbon chains (C n ) and Li-terminated linear carbon chains (Li 2 C n ), with n carbon atoms ( n = 5–10), has been very challenging for traditional electronic structure methods, due to the presence of strong static correlation eff…
Nonlinear optical (NLO) materials have a nonlinear response to the electric field associated with the light of a laser beam, leading to a variety of optical phenomena, such as the generation of new...
Abstract Mycothiol (MSH) is the major low molecular weight (LMW) thiol in Actinomycetes and functions in post-translational thiol-modification by protein S -mycothiolation as emerging thiol-protection and redox-regulatory mechanism. Here, we have used shotgun-proteomics to identify 26 S -mycothiolated proteins in the…
Anisotropic colloidal building blocks are quite attractive as they enable the self-assembly towards new materials with designated hierarchical structures. Although many advances have been achieved in colloidal synthetic methodology, synthesis of colloidal rings with low polydispersity and on a large scale remains a ch…
Researches on cargo delivery systems have received burgeoning attention and advanced rapidly. For synthetic nanodevices, polymer nanoassemblies and their inorganic-organic hybrid materials, especially smart mesoporous silica nanoparticle (MSN)-polymer hybrids (e. g., MSN@PGMAs), have attracted increasing attention in…
