Recent progress on highly tough and stretchable polymer networks has highlighted the potential of wearable electronic devices and structural biomaterials such as cartilage. For some given applications, a combination of desirable mechanical properties including stiffness, strength, toughness, damping, fatigue resistanc…
Abstract Magnesio-riebeckite from the dumps of the abandoned mine of Varenche (45°47’22’’ N, 7°29’17’’ E), Saint-Barthélemy, Nus, Aosta Valley (Italy), was studied to provide the complete mineral description (including crystal structure) and insights into the crystal-chemistry of riebeckite. The empirical formula deri…
Abstract The crystal structure and chemical formula of zvyaginite, ideally Na 2 ZnTiNb 2 (Si 2 O 7 ) 2 O 2 (OH) 2 (H 2 O) 4 , a lamprophyllite-group mineral of the seidozerite supergroup from the type locality, Mt. Malyi Punkaruaiv, Lovozero alkaline massif, Kola Peninsula, Russia have been revised. The crystal struct…
Silk sericin is a family of water-soluble proteins extracted from the silkworm cocoon. Studies have been attempted to recycle the sericin waste sericulture to develop value-added products in biomedical, pharmaceutical, cosmetic and food industries. Thus, increased production of sericin-containing wastewater from seric…
This article reports a bioinspired strategy for the preparation of robust soy protein isolate (SPI) based nanocomposites using a poly(dopamine) coating montmorillonite (D‐MMT) as reinforcement and ferric ion (Fe (III) ) as a coordination crosslinking center. Typically, the catechol groups present on MMT provide multip…
Chalcone derivatives gained significant consideration from scientific community due to their potential applications ranging from better biological activity to the efficient semiconducting properties. Present investigation deals with the in-depth study of three chalcone derivatives (2E)-1-(2,5-Dimethyl-3-thienyl)-3-(2-…
Fe-doped LiNbO3 synthesized by the combustion method to seek new multiferroic materials exhibits room-temperature ferromagnetism, as reported in our previous work [1]. In this work, the defect structure of congruent and Fe-doped LiNbO3 (0.57–3.3 mol %) powders was investigated in detail by several methods. The molar r…
ABSTRACT A novel electrophoretic deposition (EPD) method was employed for grafting multiwalled carbon nanotubes (MWCNTs) on carbon fibers, which, after impregnation with bisphenol A dicyanate ester (BADCy), synergistically reinforced BADCy matrix composites (CNT‐C/BADCy). The effect of MWCNT presence on the mechanical…
We investigate the formation mechanisms of vacancy-ordered phase and collective mass transport in epitaxial SrCrO 3−δ films using ab initio simulations within the density functional theory formalism. We show that as the concentration of oxygen vacancies ( V O ) increases, they form 1D chains that feature Cr-centered t…
In this paper, we introduce a computational model for the simulation of hypervelocity impact (HVI) phenomena which is based on the Discrete Element Method (DEM). Our paper constitutes the first application of DEM to the modeling and simulating of impact events for velocities beyond 5 kms-1. We present here the results…
Abstract Stabilization of nonequilibrium phases of inorganic solids is an art in synthetic chemistry. Herein, we demonstrate the entrapping of nonequilibrium rock salt phase of BiAgSeS in the nanocrystalline form at room temperature via kinetic colloidal synthesis. High symmetry rock salt nanocrystals undergo an unusu…
ABSTRACT Ethylenediamine (EDA) covalently functionalized graphene sheets (GS‐EDA) and acidized carbon nanotubes (MWNTs‐COOH) were first prepared, followed by synthesizing l ‐aspartic acid functionalized GS‐EDA/MWNTs‐COOH (LGC) hybrid nanomaterials by using l ‐aspartic acid as a bridging agent. Then nanocomposites of h…
ABSTRACT The accuracy of the phenomenological curing and rheological models are strongly related to the estimated start parameters and selected regression algorithms. Considering the versatile methods for model start parameter estimation (model‐free vs. model‐fitting, dynamic vs. isothermal) and regression analysis al…
ABSTRACT This work reports on a green synthetic route to produce concentrated aqueous dispersions of silver nanoparticles (AgNP) employing high‐intensity ultrasound (US) and chitosan (CS) as a nontoxic reducing agent for Ag + salts and AgNP stabilizer. The sonication simultaneously boosted the synthesis and improved t…
Amphiphile self-assembly is an essential bottom-up approach of fabricating advanced functional materials. Self-assembled materials with desired structures are often obtained through thermodynamic control. Here, we demonstrate that the selection of kinetic pathways can lead to drastically different self-assembled struc…
ABSTRACT Sulfonated aramid (SA) fiber modified graphene nanoplatelet (GnP) paper was fabricated employing simple vacuum filtration technique. The SA macromolecules were noncovalently attached on the surface of GnP through π−π interactions. Robustness of the film was characterized via dynamic mechanical analysis study.…
This paper deals with the antibacterial properties of nonwoven Co/PET and PP fabrics and woven cotton fabrics treated with the pad-dry-cure (PDC) and electrospray processes. Firstly, the surface modification of nonwoven Co/PET and PP fabrics was carried out to obtain their hydrophilicity by RF-plasma system using acry…
4A zeolites (4A) and 4A zeolites containing La (4A‐La) were prepared by kaolinite and their element composition, morphology, and structure were characterized by X‐ray fluorescence (XRF), scanning electron microscope (SEM), X‐ray diffraction (XRD) and fourier‐transform infrared spectroscopy (FTIR). 4A and 4A‐La zeolite…
