Review on the Processing and Properties of Polymer Nanocomposites and Nanocoatings and Their Applications in the Packaging, Automotive and Solar Ener…
2017
For the last decades, nanocomposites materials have been widely studied in the scientific literature as they provide substantial properties enhancements, even at low nanoparticles content. Their performance depends on a number of parameters but the nanoparticles dispersion and distribution state remains the key challenge in order to obtain the full nanocomposites’ potential in terms of, e.g., flame retardance, mechanical, barrier and thermal properties, etc., that would allow extending their use in the industry. While the amount of existing research and indeed review papers regarding the formulation of nanocomposites is already significant, after listing the most common applications, this r…

Pb-PbOHCl Composite Nanowires Synthesized by Galvanic Deposition in Template
2019
In this paper, we report a detailed study on the synthesis of composite nanowires of Pb-PbOHCl via galvanic deposition into the pores of a membrane acting as a template. PbOHCl deposition quantitatively occurs as the solution pH exceeds the value of about 4.12. Simultaneously, owing to the galvanic coupling, electro-deposition of lead occurs, so composite nanowires were formed. The role of different parameters controlling the kinetic evolution of the process, such as oxygen bubbling, solution pH, surface area and type of sacrificial anode were investigated one at a time. The results suggest that every modification accelerating the alkalization of the solution inside the template pores favor…
Activation of Stainless Steel 316L Anode for Anion Exchange Membrane Water Electrolysis
2023
The increased emphasis on renewable energy has resulted in a surge of R&D efforts into hydrogen and battery research. The intensive electrochemical environment surrounding the anodic oxygen evolution reaction (OER) has plagued both the activity and stability of the catalytic layer, substrate and porous transport layer, ultimately affecting both these industries. Herein, we report the benefits of potential cycling (PC) a 316L stainless steel felt porous transport layer (PTL) for use in anion exchange membrane water electrolysis. The PC increased surface roughness and created a CrFe5Ni2-OxHy layer through the oxidation of iron as shown by SEM, EDS, XPS, XRD and Raman spectroscopy. Post-PC tes…
Bermudagrass adaptation in the Mediterranean climate: phenotypic traits of 44 accessions
2014
The use of bermudagrass in the Mediterranean area is increasing for its outstanding tolerance to heat and drought, and its aggressive growth and high recuperative potential make it particularly suited to heavily worn areas and appreciated for sports turfs. However, the overall performance of a given genetic type can be affected by the adaptation to a specific environment. The objective of this research was to determine the variability of a number of phenotypic traits that can affect bermudagrass turf performance on a wide range of bermudagrass accessions grown in two locations in Italy. In May 2010, 44 accessions of bermudagrasses, grouped in “wild”, “improved” “hybrid” and “dwarf” types we…
Zemesgrāmatu valsts nodevu principi
2018
Bakalaura darba temats „Zemesgrāmatu valsts nodevu principi” ir izvēlēts ar mērķi izpētīt tādas valsts nodevas tiesisko regulējumu, kas iekasējama par pirkuma ceļā iegūta nekustamā īpašuma tiesību nostiprināšanu zemesgrāmatā. Darbā apskatīts nodevas tiesību normu saturs, piemērošanas kārtība, fiskālā un sociālā ietekme. Tiek pētīta nodevas izcelsme un pielietojums citu valstu tiesību sistēmās salīdzinājumā ar Latvijas vēsturisko un aktuālo regulējumu, kā arī pārbaudīta nodevas likmes un bāzes atbilstība apliekamā notikuma būtībai. Darbā tiek izvirzīta tēze, ka nodevas patiesā jēga nav atlīdzība par valsts nodrošināto īpašuma tiesību nostiprināšanas pakalpojumu, bet gan nekustamā īpašuma pir…
Latvijas un Igaunijas nodokļu sistēmu salīdzināšana
2016
Latvijas Republikas nodokļu sistēmā ir nepilnības, kas neļauj sabiedrībai attīstīties. Bakalaura darba mērķis ir, izpētot nodokļu sistēmu struktūru un likumdošanu Latvijā un Igaunijā, izstrādāt priekšlikumus Latvijas nodokļu politikas uzlabošanai. Uzdevumos ietilpst nodokļu izpēte gan Latvijā, gan Igaunijā, padziļināti analizējot tos un praktiski veicot aprēķinus. Darba rezultāti ietver secinājumus un priekšlikumus, kas iegūti, izpildot darba uzdevumus. Galvenie secinājumi – Igaunijas nodokļu sistēma ir sabiedrībai labvēlīgāka nekā Latvijā, kā arī Latvijā pastāv liels ēnu ekonomikas īpatsvars. Priekšlikumi ietver pasākumus ēnu ekonomikas samazināšanai, lai uzlabotu nodokļu iekasēšanu un adm…
Critical issues and future prospects of the secondary substation in smart grid context
2014
This paper is focused on the new role of the secondary substation in the smart grids context. This innovative view has been proposed and developed in the framework of two Research Projects: NewCabELARC Project and Reipersei Project. The latter provides a concrete and comprehensive low cost solutions for the smart grid monitoring and control, allowing the real diffusion and integration of Distributed Generation and the full exploitation of Renewable Energy Sources. In this field, this paper shows how the secondary substation (SS) takes the role of smart transducer node where innovative devices can be located, collecting the measurement data coming from the field devices (power and energy met…
Reproducibility in Electroorganic Synthesis—Myths and Misunderstandings
2021
Abstract The use of electric current as a traceless activator and reagent is experiencing a renaissance. This sustainable synthetic method is evolving into a hot topic in contemporary organic chemistry. Since researchers with various scientific backgrounds are entering this interdisciplinary field, different parameters and methods are reported to describe the experiments. The variation in the reported parameters can lead to problems with the reproducibility of the reported electroorganic syntheses. As an example, parameters such as current density or electrode distance are in some cases more significant than often anticipated. This Minireview provides guidelines on reporting electrosyntheti…
Comparison of 99mTc-Labeled Colloid SPECT/CT and Planar Lymphoscintigraphy in Sentinel Lymph Node Detection in Patients with Melanoma: A Meta-Analysis
2020
We compared the detection rate (DR) for sentinel lymph nodes (SLNS), the number of SLNs and the subjects with additional SLNs of single-photon emission computed tomography (SPECT/CT) and planar lymphoscintigraphy (PL) in patients with melanoma. Furthermore, we evaluated the impact of SPECT/CT on surgical plans. Articles containing head-to-head comparisons between SPECT/CT and PL were searched in Pubmed/MEDLINE and Scopus. The literature search was updated until December 31st, 2019. DR was calculated on a per-patient-based analysis; the studies were pooled by their odds ratios (ORs) with a random effects model to assess the significance of difference (p < 0.05). The number of additional S…
