description: Carbon quantum dots (CQDs) have attracted significant attention due to their wide range of applications. These include biosensing, bioimaging, wound healing and antibacterial applications. In this study, we examine the potential Ultraviolet (UV) radiation protection role of CQDs towards the development of viable sunscreens. The CQDs will serve as a less toxic and bio-compatible alternative to the more toxic sunscreen actives used in commercial products. Phoenix dactylifera (date) fruit pulp was used as a promising precursor for the synthesis of fluorescent CQDs. The effects of reaction temperature and reaction time on the %mass yield, hydrodynamic size and zeta potential were evaluated. The morphology and surface groups were studied before and after dialysis. The optical properties of the CQDs were examined spectrophotometrically, and the sun protection factor was calculated to obtain an insight into whether the CQDs are suitable for use as filters for the development of new sunscreens. From the results obtained, considerable sun protection factor values were obtained at small CQDs concentrations. This potentiates their use for the development of viable and less toxic sunscreens.

description: The ability to control the behavior of fluid instabilities at material interfaces, such as the shock-driven Richtmyer--Meshkov instability, is a grand technological challenge with a broad number of applications ranging from inertial confinement fusion experiments to explosively driven shaped charges. In this work, we use a linear-geometry shaped charge as a means of studying methods for controlling material jetting that results from the Richtmyer--Meshkov instability. A shaped charge produces a high-velocity jet by focusing the energy from the detonation of high explosives. The interaction of the resulting detonation wave with a hollowed cavity lined with a thin metal layer produces the unstable jetting effect. By modifying characteristics of the detonation wave prior to striking the lined cavity, the kinetic energy of the jet can be enhanced or reduced. Modifying the geometry of the liner material can also be used to alter jetting properties. We apply optimization methods to investigate several design parameterizations for both enhancing or suppressing the shaped-charge jet. This is accomplished using 2D and 3D hydrodynamic simulations to investigate the design space that we consider. We also apply new additive manufacturing methods for producing the shaped-charge assemblies, which allow for experimental testing of complicated design geometries obtained through computational optimization. We present a direct comparison of our optimized designs with experimental results carried out at the High Explosives Application Facility at Lawrence Livermore National Laboratory.

In the present report, we investigated the validity of the mentioned electronic structure rules in the explaining of the chemical reactivity or stability of fullerenes. For this purpose, important quantum chemical parameters like frontier orbital energies, hardness, electronegativity, softness and electrophilicity for carbon fullerenes (from C20 to C240) were calculated and discussed. As a result, it was shown that none of the electronic construction principles mentioned are fully sufficient. To explain the chemical reactivity of fullerenes, new electronic structure rules or new parameters are required

description: Observations suggest that red central galaxies align closely with their group galaxies and the large-scale environment.This finding was also replicated in simulations, which added information about the alignment of the stars that form the galaxies with the dark matter in the halo they inhabit. These results were obtained for the present universe. Our study aims to build upon previous findings by examining the evolution of central galaxy alignment with their environment, as well as the alignment between their stellar and dark matter components. Based on previous studies, in this work, we describe the evolution of the alignment of bright central galaxies over time and try to understand the process leading to the current observed alignment. By employing the merger trees from the simulation, we track the alignment evolution of the central galaxy sample at z=0 used in a previous study, whose results correspond to the observations. In particular, we exploit the anisotropic correlation function to study the alignment of the central galaxies with the environment and the probability distribution of the angle between the axes of the shape tensor calculated for each component to deepen the analysis of the stellar and dark matter components. A description was given of the evolution of alignment in bright central galaxies with a focus on the distinctions between red and blue galaxies. Furthermore, it was found that the alignment of the dark matter halo differs from that of the stellar material within it. According to the findings, the assembly process and mergers influenced the evolution of alignment

description: In the present study, the effects of classical oils (kerosene, fuel oil) and their mixtures (25% Kerosene + 75% fuel oil; 50% Kerosene + 50% fuel oil; 75% Kerosene + 25% fuel oil) on the enrichment of Soma Lignite coal by flotation were investigated. The effects of collector amount on combustible recovery, ash reduction and efficiency index, which are among the parameters that are effective in the enrichment of Soma Lignite coal using both pure and mixed classical oils, were analyzed. In the experiments made with pure oils, the best value in terms of combustible part recovery was obtained with fuel oil. Combustible recovery obtained from experiments with mixtures are higher than those with pure oils. It should be noted that especially in experiments with 25% kerosene + 75% fuel oil, higher combustible recovery values were obtained. According to these results, it shown that depending on the oil or emulsion type, the degree of processes taking place at the coal-air-water interface and the presence of unstable functional groups in the oils seem to significantly affect the flotation performance.

description: In the context of the study of the size-age relationship observed in star clusters in the Large Magellanic Cloud and the investigation of its origin, here we present the determination of the structural parameters and the dynamical age of the massive cluster NGC 1835. We have used a powerful combination of optical and near-ultraviolet images acquired with the WFC3 onboard the HST to construct the star density profile from resolved star counts, determining the values of the core, half-mass and tidal radii through the comparison with the King model family. The same data also allowed us to evaluate the dynamical age of the cluster by using the 'dynamical clock'. This is an empirical method that quantifies the level of central segregation of blue stragglers stars (BSSs) within the cluster half-mass radius by means of the A+ parameter, which is defined as the area enclosed between the cumulative radial distribution of BSSs and that of a reference (lighter) population. The results confirm that NGC 1835 is a very compact cluster with a core radius of only 0.84 pc. The estimated value of A+ ($0.30\pm 0.04$) is the largest measured so far in the LMC clusters, providing evidence of a highly dynamically evolved stellar system. NGC 1835 nicely fits into the correlation between A+ and the central relaxation time and in the anti-correlation between A+ and the core radius defined by the Galactic and the Magellanic Cloud clusters investigated to date.

description: The suitability of phyto-synthesized metal oxide nanoparticles for producing super-hydrophobic coatings for potential biomedical, agricultural and industrial applications was studied for the first time. ZrO2, CeO2 and SnO2 nanoparticles were synthesized through a green and facile method by using the aqueous leaf extract of the widely distributed Azadirachta indica as capping agent with over 60 % percentage mass yield. Organic groups acting as capping/stabilizing agents and siloxane attachments were identified using Fourier transform infra-red (FTIR). Tiny spherical ZrO2 nanoparticles, angular shaped CeO2 particles and a bed of tiny SnO2 particles with overall predominant particle sizes less than 15 nm were observed using field emission scanning electron microscope (FESEM). As expected, non-wettability of surfaces generally increased with increasing siloxane coupling of the nanoparticles. At a nanoparticle to fluoroalkylsilane mole ratio of 1:1, non-wettable, highly non-wettable and super-hydrophobic surfaces were obtained for CeO2, SnO2 and ZrO2 nanoparticles, respectively. The extent of initial phytochemical adsorption, size of the nanoparticles and extent of agglomeration are major factors that influence the coupling of fluoroalkylsilanes and consequently, the wettability of surfaces produced.

Clystopsenella Kieffer, 1911: 204. Type species: Clystopsenella longiventris Kieffer, 1911, by monotypy.
Diagnosis and comments. The genus can be readily distinguished from other scolebythids by the possession of a modified region on the medial surface of the sternum V of females, consisting of an elevated area with patches of appressed setae on each side. The forewing has a relatively well-developed venation, with medial, marginal and submarginal cells closed by tubular veins. In contrast to Ycaploca Nagy, Clystopsenella lacks a strong medial elevation on the frons with carinate sides; the vein 2rs-m is inserted anteriorly on the marginal cell, and the vein 2r-rs is shorter than 1m-cu; the posterior surface of the propodeum is not rugulose medially; the first flagellomere is longer than two-thirds of the length of the second one; and the tibial spur formula is 1:2:2. Differently from Scolebythus Evans, species of Clystopsenella have the occipital carina completely absent or vestigial and restricted to its lateral portions, the malar space longer than one-half of the basal mandibular width, and the posterior ocelli distanced from each other by about 3 × anterior ocellus width or more. In addition, Clystopsenella has relatively robust legs in comparison to the other genera.

description: Primordial black holes (PBH) can efficiently form black hole binaries in the early universe. We update the resulting constraints on PBH abundance using data from the third observational run (O3) of LIGO-Virgo-KAGRA. To capture a wide range of PBH scenarios, we consider a variety of mass functions, including critical collapse in the QCD epoch in the presence of non-Gaussianities. Applying hierarchical Bayesian analysis to a population binaries consisting of primordial and astrophysical black holes, we find that, in every scenario, the PBHs can make up at most $f_{\rm PBH} \lesssim 10^{-3}$ of dark matter in the mass range $1-200~M_\odot$. The shape and strength of the constraints are insensitive to the type of non-Gaussianities, the modifications to the mass function during the QCD epoch, or the modelling of the astrophysical PBH population.

Subjects: Nickel; Chromium; Electrodeposition; Filter membranes; Electrolytic cleaning.

description: Porosity in coatings is a vital parameter for many engineering applications. Having a porous coating is good with respect to few aspects and bad with respect to others. One of the main applications of porous metal coating is in the field of membrane filters for oil water separation to deal with industrial waste water and off-shore oil spill. It is also used for electrolytic cleaning (purification) of water. Studying the nature of formation and development of pores is being carried out by many researchers to determine the parameters affecting the porosity of coatings. Optimizing the parameters to obtain a favourable coating with least defect is the idea behind these research topics. Nickel and chromium coatings are widely used for many industrial applications because of specific properties. Nickel-chromium alloy coatings offer better hardness, wear and corrosion resistance compared to individual nickel or chromium coatings. The alloy coatings are observed to be porous in nature compared to individual nickel and chromium coatings. Controlling the porosity of the deposition by varying the process parameters is a very interesting topic of research as it greatly influences the properties. In the present work, the coating microstructures of nickel-chromium alloys developed by electrodeposition techniques are analysed and evaluated using Field Emission Scanning Electron Microscopy (FESEM) for varying current densities and plating time resulting a good uniform coating with varying porosity

description: Magnetic materials with negative spin polarization have attracted attention for their potential to increase the design freedom of spintronic devices. This study investigated the effects of off-stoichiometry on the atomic ordering, microstructure, and magneto-transport properties in Mn2+xV1-xGa (x = -0.2, 0, +0.2, +0.4) Heusler alloy films, which are predicted to have large negative spin polarization derived from a pseudo band gap in the majority spin channel. The Mn2+xV1-xGa films epitaxially grown on MgO(001) substrates exhibits variations of B2 and L21 order with the Mn concentration. A high-quality L21 ordered film was achieved in the Mn-rich composition (x = +0.2) with B2 and L21 order parameters of 0.97 and 0.86, respectively, and a saturation magnetization of 1.4 μB/f.u, which agrees the Slater-Pauling rule. Scanning transmission electron microscopy observations showed that B2 and L21 phases coexist in Mn-poor and stoichiometric films, while the L21 phase is dominant in the Mn-rich film with small amounts of Mn-V and Mn-Ga disorders, as revealed by laboratory and anomalous X-ray diffraction. Combined first-principles calculations and anisotropic magnetoresistance analysis confirm that the addition of excess Mn preserves the high spin polarization by suppressing the formation of detrimental antisites of V atoms occupying Mn sites. Therefore, the Mn-rich composition is promising for negatively spin-polarized charge injection in Mn2VGa-based spintronic applications.

description: An agricultural residue, cowpea (Vigna unguiculata) husk (CPH), was used for the removal of Congo red dye from aqueous solution using a batch adsorption method. The adsorbent was characterized using FTIR and SEM techniques. The optimization of adsorption variables including pH, contact time, adsorbent dosage and initial dye concentration at 25 °C were also carried out. The results indicated the dependence of the adsorption system on the studied variables and equilibrium was attained in 60 min. The adsorption kinetics was fitted to four models (pseudo first order, pseudo second order, Elovich and intra-particle diffusion) to validate the kinetics, which resulted in pseudo second order as the best model for the description of Congo red dye uptake. Equilibrium isotherm modeling was also carried out using the Langmuir, Freundlich, and Temkin models. The Langmuir isotherm relatively giving the best fitting to the experimental results. The maximum loading capacity (qm) of the adsorbent for Congo red obtained from the Langmuir isotherm model is 161.29 mg/g. This result indicates that the CPH residue could serve as a good adsorbent for the removal of Congo red dye from aqueous system

description: Various stellar objects experience a velocity kick at some point in their evolution. These include neutron stars and black holes at their birth or binary systems when one of the two components goes supernova. For most of these objects, the magnitude of the kick and its impact on the object dynamics remains a topic of debate. We investigate how kicks alter the velocity distribution of objects born in the Milky Way disc, both immediately after the kick and at later times, and whether these kicks are encoded in the observed population of Galactic neutron stars. We simulate the Galactic trajectories of point masses on circular orbits in the disc after being perturbed by an isotropic kick, with a Maxwellian distribution of magnitudes with $σ=265$ km/s. Then, we simulate the motion of these point masses for $200$ Myr. These trajectories are then evaluated, either for the Milky Way population as a whole or for those passing within two kiloparsecs of the Sun, to get the time evolution of the velocities. During the first $20$ Myr, the bulk velocity of kicked objects becomes temporarily aligned to the cylindrical radius, implying an anisotropy in the velocity orientations. Beyond this age, the velocity distribution shifts toward lower values and settles to a median of $\sim200$ km/s. Around the Sun, the distribution also loses its upper tail, primarily due to unbound objects escaping the Galaxy. We compare this to the velocities of Galactic pulsars and find that pulsars show a similar evolution with characteristic age. The shift of the velocity distribution is due to bound objects spending most of their orbits at larger radii after the kick. They are, therefore, decelerated by the Galactic potential. We find the same deceleration to be predicted for nearby objects and the total population and conclude it is also observed in Galactic pulsars.

description: A natural clay was used as a low-cost adsorbent for simultaneous removal of Ni2+ ions and methylene blue (MB) dye from an aqueous solution. FTIR, XRD and SEM analysis were used to characterize the adsorbent. Batch adsorption methodology was used to evaluate the effect of solution pH, initial pollutants concentration and contact time on adsorption. The equilibrium isotherm data was analyzed using the Langmuir, Freundlich, Temkin and Dubinin–Radushkevich (D–R) isotherm model. The Freundlich isotherm model provided the best ﬁt to the experimental data for both pollutants as indicated by the values of the regression coefﬁcient. The kinetic data was analyzed using the pseudo-ﬁrst order, pseudo-second order equations, the Elovich equation and intraparticle diffusion rate equation. The pseudo-second-order model was found to explain the adsorption kinetics most effectively to the experimental data for both pollutants. The presence of intraparticle diffusion mechanism was indicated, although it was not the sole rate determining step. It was concluded that Natural Clay is an effective adsorbent for removal for simultaneous removal of Ni2+ ions and methylene blue (MB) dye from aqueous solution.

description: Pipelines of state-of-the-art spectrographs dedicated to planet detection provide, for each exposure, series of Cross-Correlation Functions (CCFs) built with a Binary Mask (BM), and the absolute radial velocity (RV) derived from Gaussian fit of a weighted average CCF$_{tot}$ of the CCFs. Here we tested the benefits of the application of the shift finding algorithm developed by Pierre Connes directly to the total CCF$_{tot}$, comparing the resulting RV shifts (DRVs) with the results of the Gaussian fits. In a second step, we investigated how the individual DRV profiles along the velocity grid can be used as an easy tool for detection of stellar line shape variations. We tested this new algorithm on 1151 archived spectra of the K2.5 V star HD 40307 obtained with ESO/ESPRESSO during a one-week campaign in 2018. Tests were performed based on the comparison of DRVs with RVs from Gaussian fits. DRV profiles along the velocity grid (DRV(i)) were scrutinized and compared with direct CCF$_{tot}$ ratios. The dispersion of residuals from a linear fit to RVs from 406 spectra recorded within one night, was found to be $σ$=1.03 and 0.83 ms$^{-1}$ for the Gaussian fit and the new algorithm respectively, a significant 20\% improvement in accuracy. The two full one-week series obtained during the campaign were also fitted with a 3-planet system Keplerian model. The residual divergence between data and best-fit model is significantly smaller for the new algorithm than for the Gaussian fit. This new algorithm is an easy tool allowing to obtain additional diagnostics on the RV measurements in series of exposures. It increases the accuracy of velocity variation determinations. Also, departures from constancy of the DRVi profiles, as well as varying differences between RVs from this new method and RVs from a Gaussian fit provide diagnostics of line shape variations due to stellar activity.

Density functional theory and molecular dynamic simulation studies on the corrosion inhibition of some thiosemicarbazide derivatives on aluminum metal
Creators: name: Muhammad, Thomas Aondofa Nyijime
Publisher: name: Journal of Applied Surfaces and Interfaces
Year: 2021
Subjects: Aluminum; Thiosemicarbazides; Corrosion inhibition; DFT; Molecular dynamics simulation.

description: Aluminum (Al), one of the most comercially used metals is also susceptible to corrosion like iron and zinc when subjected to corrosive environments, either in the industries or during applications in general. One major method of controlling corrosion of Al is through the use of inhibitors which are usually compounds containing heteroatoms, conjugated systems or which are relatively large in size. One of such inhibitors, thiosemicarbazide derivatives were reported in literature as an Al inhibitor in 2M HCl solution through experimental studies. In this study, computational methods were used to further provide an indepth explanation into the mode and mechanism of the thiosemicarbazides inhibition on Al surface. Parameters including quantum chemical through DFT and molecular dynamic simulations of studied molecules on Al surfaces were conducted. Results obtained through calculation of adsorption or binding energies of these thiosemicarbazides were in good agreement with the experimentally reported results elsewhere. With respect to the calculated adsorption or binding energies, thier relatively low values infered that the compounds are weakly adsorbed onto the surface of Al through Van der Waals forces and therefore obey the mechanism of physical adsorption. It was also established that the reference molecule thiosemicarbazide (TSC) was least adsorbed when compared to the other five molecules of its derivatives. The order of the inhibition efficiency as determined is as follows: PBT>DTC>DPT>PCT>PTC>TSC

description: Our purpose is to study the effect of binary companions located within the first 10 stellar radii from the primary AGB star. In this work, we target the mass-losing carbon star V Hydrae (V Hya), looking for signatures of its companion in the dust forming region of the atmosphere. The star was observed in the L- and N-bands with the VLTI/MATISSE instrument at low spectral resolution. We reconstructed images of V Hya's photosphere and surroundings using the two bands and compared our interferometric observables with VLTI/MIDI and VISIR archival data. To constrain the dust properties, we used DUSTY to model the spectral energy distribution. The star is dominated by dust emission in the L- and N- bands. The VISIR image confirms the presence of a large-scale dusty circumstellar envelope surrounding V Hya. The MATISSE reconstructed images show asymmetric and elongated structures in both infrared bands. In the L-band, we detected an elongated shape of approximately 15 mas, likely to be of photospheric origin. In the N-band, we found a 20 mas extension North-East from the star, and perpendicular to the L-band elongated axis. The position angle and the size of the N-band extension match the prediction of the companion position at MATISSE epoch. By comparing MATISSE N-band with MIDI data, we deduce that the elongation axis in the N-band has rotated since the previous interferometric measurements 13 years ago, supporting the idea that the particle enhancement is related to the dusty clump moving along with the companion. The MATISSE images unveil the presence of a dust enhancement at the companion position, opening new doors for further analysis on the binary interaction with an AGB component.

Restorative biocompatible polymer composites on the base of epoxy-resin filled by surface-modified disperse utilizated solid waste of industrial paper products
Creators: name: Starokadomsky, V. Halysh

Subjects: Paper industry waste; Epoxy-resin; Mechanical properties; Resistance to swelling

description: The paper industry is one of the sources of environment pollution. Therefore, the problem of efficient utilization of such wastes is an urgent one. One of the possible effective methods of paper industry waste recycling can be the application in epoxy composites. The review of literature proves a high scientific and industrial actuality of this thematic. Optical microscopy shows that 20 wt% of micro- and meso-particles of lignocellulose from waste-paper utilization leads to changes in morphology of composite due to interactions between phases. As result, the key mechanic (modulus at bending, resistance to wear) and resistant (swelling, fire- resistance) parameters changed. At the same time, 20wt% filling do not importantly change compression and bending strength parameters. Filled composites (as fresh as aged) are noticeable more resistant in acetone-containing solvents. Effect of filling on resistance in H2O2 depends on its concentration and age of templates: aged 20%-filled composites are more resistant than unfilled (in 35% H2O2), but fresh 10%-filled composite destruct quickly (unlike unfilled) in high-concentrated (60%) H2O2

description: The ever-increasing use of generative models in various fields where tabular data is used highlights the need for robust and standardized validation metrics to assess the similarity between real and synthetic data. Current methods lack a unified framework and rely on diverse and often inconclusive statistical measures. Divergences, which quantify discrepancies between data distributions, offer a promising avenue for validation. However, traditional approaches calculate divergences independently for each feature due to the complexity of joint distribution modeling. This paper addresses this challenge by proposing a novel approach that uses divergence estimation to overcome the limitations of marginal comparisons. Our core contribution lies in applying a divergence estimator to build a validation metric considering the joint distribution of real and synthetic data. We leverage a probabilistic classifier to approximate the density ratio between datasets, allowing the capture of complex relationships. We specifically calculate two divergences: the well-known Kullback-Leibler (KL) divergence and the Jensen-Shannon (JS) divergence. KL divergence offers an established use in the field, while JS divergence is symmetric and bounded, providing a reliable metric. The efficacy of this approach is demonstrated through a series of experiments with varying distribution complexities. The initial phase involves comparing estimated divergences with analytical solutions for simple distributions, setting a benchmark for accuracy. Finally, we validate our method on a real-world dataset and its corresponding synthetic counterpart, showcasing its effectiveness in practical applications. This research offers a significant contribution with applicability beyond tabular data and the potential to improve synthetic data validation in various fields.

description: In this study, the effect of recycled ceramic waste particles on the curing reaction and thermal degradation of unsaturated polyester resin has been studied kinetically. Methyl ethyl ketone peroxide and cobalt octoate were used as initiator and promotor, respectively. The porcelain powder obtained from ceramic waste was used as filler. The effect of methyl ethyl ketone peroxide and porcelain powder were investigated by measuring the gel time and exotherm behavior. Also, thermal properties have been carried out using TGA at different heating rates in an argon atmosphere, and the results were analyzed by the Friedman method. The results indicate that the curing process is affected by the incorporation of ceramic particles in two ways. Therefore, the use of ceramic particles increases the induction time and decreases the exotherm properties of unsaturated polyester resin. In addition, the results obtained by Friedman method demonstrates that the incorporation of ceramic particles in the resin increases the activation energy, and consequently improves the thermal stability of unsaturated polyester resin

description: As ground-based all-sky astronomical surveys will gather millions of images in the coming years, a critical requirement emerges for the development of fast deconvolution algorithms capable of efficiently improving the spatial resolution of these images. By successfully recovering clean and high-resolution images from these surveys, the objective is to deepen the understanding of galaxy formation and evolution through accurate photometric measurements. We introduce a two-step deconvolution framework using a Swin Transformer architecture. Our study reveals that the deep learning-based solution introduces a bias, constraining the scope of scientific analysis. To address this limitation, we propose a novel third step relying on the active coefficients in the sparsity wavelet framework. We conducted a performance comparison between our deep learning-based method and Firedec, a classical deconvolution algorithm, based on an analysis of a subset of the EDisCS cluster samples. We demonstrate the advantage of our method in terms of resolution recovery, generalisation to different noise properties, and computational efficiency. The analysis of this cluster sample not only allowed us to assess the efficiency of our method, but it also enabled us to quantify the number of clumps within these galaxies in relation to their disc colour. This robust technique that we propose holds promise for identifying structures in the distant universe through ground-based images.
