Asbestos-containing pottery shards collected in the northeast of Corsica (Cap Corse) and dating from the 19th century, or earlier, have been analyzed by SEM-EDS, XRPD, FTIR and Raman microspectroscopy. Blue (crocidolite) and white (chrysotile) asbestos fiber bundles are observed in cross-sections. Most of the asbestos…
Abstract We studied computationally the effects of TeO defects on the distribution of reduced centers, V4+, in the MoVNbTeO M1 bulk material. To this end, we selected a distribution of V and Mo centers, constructed models with periodic boundary conditions, and applied a hybrid DFT approach. We identified two main fact…
Five thieno[3,4- c ]pyrrole-4,6-dione (TPD)-terthiophene copolymers, PHT, P1F3HT, P1F1HT, P3F1HT, and PFT, having 0, 25, 50, 75, and 100% of fluorine substituents on the center of terthiophene exhibit a progressive increase of open-circuit voltage ( V OC ), short-circuit current density ( J SC ), and hence a power con…
Cellulose nanocrystal (CNC) gold nanoshell was prepared using a polymer-coated CNC as a template. A seed-mediated shell growth approach ( ex situ ) was employed, gold nanoparticles (AuNPs) of two sizes were prepared, and the effect of the size of AuNP on the shell quality (smoothness, evenness, and continuity) was elu…
In this paper, the microstructure and mechanical properties of two magnesium matrix composites—a hypoeutectic with 1.9 wt% Mg2Si phase and a hypereutectic with 19 wt% Mg2Si compound—were analyzed. The investigated materials were prepared using the gravity casting method. Microstructure analyses of the fabricated compo…
Abstract In this work, we performed a systematic study on a hybrid plasmonic system to elucidate a new insight into the mechanisms governing the fluorescent enhancement process. Our lithographically defined plasmonic nanodisks with various diameters act as receiver and transmitter nano-antennas to outcouple efficientl…
The present study investigated the effects of adding 20 vol.% biodiesel to petroleum diesel (to produce a mixture termed B20) on the physical properties and reactivity of the resulting exhaust soot particles. Tests were performed at different engine loads of a constant speed, and the soot particles from the combustion…
Amyloid-β (Aβ) aggregates are believed to be one of the main causes of Alzheimer's disease. Aβ peptides form fibrils having cross β-sheet structures mainly through primary nucleation, secondary nucleation, and elongation. In particular, self-catalyzed secondary nucleation is of great interest. Here, we investigate the…
A model hydrochar was synthesized from glucose at 180 °C and its Cu(II) sorption capacity was studied experimentally and computationally as an example of molecular-level adsorbent design. The sorption capacity of the glucose hydrochar was less than detection limits (3 mg g−1) and increased significantly with simple al…
In this article, a novel wideband metal-only transmitarray based on 1-bit polarization rotation element is proposed. First, a novel wideband polarization rotation element is designed, which consists of four metallic layers without any substrate layers. The element can be used to rotate polarization of the transmission…
Originally developed for the structural biology field, lipid bicelle nanostructures composed of long- and short-chain phospholipid molecules have emerged as a useful interfacial science tool to fabricate two-dimensional supported lipid bilayers (SLBs) on hydrophilic surfaces due to ease of sample preparation, scalabil…
Magnesium alloys have been known as the next generation material for lightweight body structures. Pulsating hydroforming is an effective method to improve magnesium alloy sheet forming performance, and the formed parts are characterized by lightweight, high-specific strength and stiffness. The deformation performance…
An appropriately designed periodic lattice in graphene can cause plasmonic modes, absorbing a specific THz frequency band, minimizing transmission. A suitable Fabry-Perot cavity, on the other hand, can resonate at another desired frequency in the nearby THz band, enhancing the transmittance. Integrating, these two typ…
Due to mass diffusion issues, it is challenging to prepare black-phase thick formamidinium-based perovskite (FAPbI 3 ) films via vapor approaches. Precursor engineering is employed here to overcome the dilemma of thorough reaction and black-phase stabilization of FAPbI 3 in a sequential vapor approach. For the first t…
Conventional cement production process emits tons of carbon dioxide gas which is one of the greenhouse gases that influence the environment across the world. Discovering the alternative construction material with the eco-friendly process and the performance similar to or greater than ordinary Portland cement has been…
Trivalent actinides generally exhibit ninefold coordination in solution. 2,6-Bis(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (nPr-BTP), a tridentate nitrogen donor ligand, is known to form ninefold coordinated 1:3 complexes, [An(nPr-BTP) 3 ] 3+ (An = U, Pu, Am, Cm) in solution. We report a Cm(III) complex with tenfold co…
In this study, a new method was proposed to study the relaxation properties of carbon fiber reinforced plastics (CFRP) fabric under axial tension. Under the condition of constant temperature and humidity, six groups of 168 h stress relaxation tests were conducted. Considering the influence of the prestress level, the…
In this study, the interaction of Fe3O4@CaAl-LDH@L-Dopa nanoparticles (NPs) with human serum albumin (HSA) was investigated in simulated physiological conditions applying UV-visible, fluorescence, and circular dichroism (CD) spectroscopic techniques. The consequences of UV-vis and CD spectroscopy demonstrated that the…
Abstract For experimental research to offer valuable insights and predictions, its results and interpretation need to be properly validated. When the experiments deal with complex systems, such as biological materials, multicomponent mixtures, or multiple phases, the use of the rigorous scientific method is essential.…
In this paper, the reaction mechanism for the adsorption of Zn2+ by synthetic triclinic Na-birnessite was studied by reacting synthetic triclinic Na-birnessite with Zn2+ in solution, thereby providing a theoretical basis for the purification of heavy metal ions in acid soil and water by triclinic birnessite. The adsor…
