Influence of a Cu–zirconia interface structure on CO2 adsorption and activation
2021
CO2 adsorption and activation on a catalyst are key elementary steps for CO2 conversion to various valuable products. In the present computational study, we screened different Cu–ZrO2 interface structures and analyzed the influence of the interface structure on CO2 binding strength using density functional theory calculations. Our results demonstrate that a Cu nanorod favors one position on both tetragonal and monoclinic ZrO2 surfaces, where the bottom Cu atoms are placed close to the lattice oxygens. In agreement with previous calculations, we find that CO2 prefers a bent bidentate configuration at the Cu–ZrO2 interface and the molecule is clearly activated being negatively charged. Strain…

HPLC Determination of Polyphenols from Calendula officinalis L. Flowers
2017
Abstract Romanian spontaneous flora provides a lot of resources for the determination of different chemical compounds. This study uses flower samples from Calendula officinalis L. extracted through maceration. The chemical compounds determined were: (+)-catechin, caffeic acid, chlorogenic acid, cinnamic acid, ferulic acid, gallic acid, rutin, resveratrol and quercetin. They were analyzed by using an optimized HPLC method. (+)-Catechin, caffeic acid, chlorogenic acid and quercetin could not be identified in the analyzed samples. The greatest amount of phenolic compound found was rutin and the smallest quantity was determined for ferulic acid. The quantified compounds have proven to have bene…
Current Status on the Functional Characterization of Chemosensory Receptors of Cydia pomonella (Lepidoptera: Tortricidae)
2018
Cydia pomonella (Lepidoptera: Tortricidae) is a major pest of apple, pear and walnuts. For its control, alternative strategies targeting the olfactory system, like mating disruption, have been combined with insecticide applications. The efficacy of these strategies headed the direction of efforts for the functional characterization of codling moth chemosensory receptors to implement further control methods based on chemical sensing. With the advent of transcriptomic analysis, partial and full-length coding sequences of chemosensory receptors have been identified in antennal transcriptomes of C. pomonella. Extension of partial coding sequences to full-length by polymerase chain reaction (PCR…

Multifunctional polymer/inorganic hybrid nanoparticles with controlled structure
2019
Hybrids and composite materials offer a synergic combination of polymer and inorganic features. The integration of specific functionalities at the nanoscale leads to the improvement of the characteristics of macroscopic materials. In this context, the attractiveness of multifunctional polymer–inorganic nanoparticles is remarkable. The relative arrangement of the components forming the hybrid nanostructure determines the accessibility of the functionalities, the properties, and the applicability of the material. Colloidal methods have been traditionally used for the preparation of hybrid nanoparticles, but the precise control of their morphology remains still a challenge. The objective of th…
ReO as a Brønsted acidic modifier in glycerol hydrodeoxygenation : Computational insight into the balance between acid and metal catalysis
2023
A computational study for the competitive conversion of glycerol to 1,2-propanediol and 1,3-propanediol is presented, considering a two-step sequence of dehydration followed by hydrogenation. The elementary steps for dehydration, i.e., breaking of C–H followed by C–OH or vice versa, were studied computationally both on the Rh metal surface and the acid-modified ReOH–Rh surface in order to understand the role of the acid promoter. While the acid modifier can catalyze the C–OH cleavage, the activation energy for the C–H cleavage was found to be considerably smaller on both pure and acid-doped Rh(111) surfaces, and breaking the secondary C–H bond is kinetically favored over breaking the termin…

Bakalaura darbs “Disfunkcionālas ģimenes ietekme uz bērnu – speciālistu un cilvēku no šādām ģimenēm viedokļi” ir par personām, kuras ir auguši disfunkcionālā ģimenē. Darba mērķis ir noskaidrot indivīdu, kuri auguši disfunkcionālā ģimenē un speciālistu, kuri ikdienā strādā ar bērniem no disfunkcionālām ģimenēm viedokli par ietekmi, ko atstāj augšana šādā ģimenē. Darba uzdevums ir noskaidrot personu, kuri auguši disfunkcionālā ģimenē un speciālistu, kuri ikdienā strādā ar bērniem no disfunkcionālām ģimenēm viedokli par ietekmi, ko atstāj augšana šādā ģimenē, kā arī salīdzināt abu atlasītu grupu viedokļus un noskaidrot, kā personas no disfunkcionālām ģimenēm pārvar bērnībā gūto traumu. Pēc dar…
Balance confidence and functional balance are associated with physical disability after hip fracture
2012
Background. This cross-sectional study investigated the associations between balance confidence, functional balance, and physical disability among older people after hip fracture. Material and methods. The study utilizes baseline data of two randomized controlled trials (ISRCTN34271567 and ISRCTN53680197). The participants were 159 community-dwelling over 60-year-old people. Health, fracture status, the date and type of surgery, and contraindications for participation were assessed in a clinical examination. Balance confidence was assessed by the Activities-specific Balance Confidence Scale (ABC) and functional balance by the Berg Balance Scale. Physical disability was assessed by a questio…
