The influence of Pt doping on the lattice structure, magnetism, elastic moduli, and martensite transition of Ni2MnGa and Ni2FeGa Heusler alloys was studied using first-principles calculations. We investigated Pt substitution at all three different sites of Ni, Mn (Fe), and Ga with different concentrations. Partial Pt…
Magnesium borohydride, Mg(BH4)2, and calcium borohydride, Ca(BH4)2, are promising materials for hydrogen storage. Mixtures of different borohydrides have been the subject of numerous researches; however, the whole Mg(BH4)2-Ca(BH4)2 system has not been investigated yet. In this study, the phase stability and the hydrog…
Here, we report a straightforward approach to fabricate antifogging antireflective dual-function nanostructured coatings, where antireflective nanograsses were etched into antifogging polymer coatings by self-masking reactive ion etching (RIE). The transmittance of coatings increases with the etching time, and the max…
We have fabricated a pillar structure phase change memory (PCM) with the prototypical phase change material Ge2Sb2Te5. Using a Low Current SET (LCS) pre-operation, the devices can operate with an ultralow RESET current density and have multilevel cell (MLC) capability, and these features both contribute to high storag…
Multiferroic materials that demonstrate magnetically driven ferroelectricity have fascinating properties such as magnetic (electric) field-controlled ferroelectric (magnetic) response that can be used in transformative applications including fast-writing, power-saving, and nondestructive data storage technologies in n…
Ferroresonance causes overvoltage and excessive current flow on potential transformers (PT), which can cause substantial damage to PTs and interrupt the power system normal operation. In this article, a sustained overvoltage event on a de-energized 138 kV bus after the circuit breakers were opened to clear a phase A t…
An anisotropic coding metasurface (CM) is proposed for achieving circular-to-linear polarization conversion and beam deflection. Different phase coding consequences were independently achieved for two orthogonal linear polarized (LP) waves. Thus by elaborately designing coding sequences of the metasurfaces, different…
Biaxially oriented polypropylene (BOPP) films are currently an indispensable material for pulse capacitor production. Research on the structure-activity relationship of BOPP films is an important way to optimize its manufacturing process and achieve high energy density. In this article, the influences of three key str…
Properties arising from ordered periodic mesostructures are often obscured by small, randomly oriented domains and grain boundaries. Bulk macroscopic single crystals with mesoscale periodicity are needed to establish fundamental structure-property correlations for materials ordered at this length scale (10-100 nm). A…
Plastic flow at small scales is generally observed to be intermittent, whereas the stress-strain behavior of bulk crystals is mostly smooth. Here we find that when the external deformation rate of small-scale crystals approaches the speed of the crystallographic slip velocity, an intermittent-to-smooth transition of p…
Understanding the mechanical properties of nanoconfined polymers is essential in the design of nanostructured soft materials. Here, we investigate the mechanical properties of free-standing polymer thin films by employing an atomistically based coarse-grained (CG) modeling approach. By examining three representative C…
The representatives of relaxor ferroelectric (1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3 (PZNT) and (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMNT) have been extensively studied due to their excellent dielectric and piezoelectric properties near the morphotropic phase boundary (MPB). However, low rhombohedral to tetragonal phase transition te…
Multi-walled carbon nanotubes (MWCNTs) in the form of "forests" were synthesized directly on the surface of stainless steel (SS) mesh from ethanol flame volume. The growth dependence of the MWCNT forests on the porosity of SS mesh substrate and the morphologies and growth mechanism of the MWCNT forests were investigat…
The purpose of this review is to compare and contrast silicate natural glasses with so-called un-natural glasses, bringing together literature and common issues in geology and technical glass science and engineering. The review is organized into three proposed ‘frontiers’ of glass science of interdisciplinary interest…
The European Commission has recognized nanotechnologies as extremely promising for increasing competitiveness of different sectors of the economy. On account of climate changes and the quest for food security, they are an effective way of solving key problems in the agrarian sector. Nowadays nanotechnologies are widel…
Abstract Four complexes, namely, [Ln 2 ( L2 ) 2 (NO 3 ) 4 ]. 2CH 3 OH (Ln = Tb ( 1 ), Dy ( 2 ), Ho ( 3 ), Er ( 4 ), and L2 = ( E )-2-methoxy-6-(((pyridin-2-ylmethyl)imino)methyl)phenol), were obtained by reacting ( E )-2-((3-methoxy-2-oxidobenzylidene)amino)ethanesulfonate ( L1 ), Ln(NO 3 ) 3 ·6H 2 O, and 2-aminomethy…
The synthesis and study of colloidal molecules, that is to say clusters of a small number of colloidal entities that resemble the configuration of atoms in molecules both in constituent size and angular arrangement to that of valence shell electron pair repulsion model-related space-filling geometries, are of continue…

We measured the near-field infrared response of ${\mathrm{MnPS}}_{3}$ in bulk, few-, and single-layer form and compared our findings with traditional far-field vibrational spectroscopies, a symmetry analysis, and first-principles lattice dynamics calculations.

Abstract An advanced mathematical approach to describe the influence of corrosion products on the corrosion rate is presented here. The related model can be used as input equation for numerical predictive corrosion simulations or simply as an empirical model, to extrapolate experimental data of corrosion tests to long…
