Kernels and Graphs on M25 + H
2023
Codes related to article "Graphs and Kernelized Learning Applied to Interactions of Hydrogen with Doped Gold Nanoparticle Electrocatalysts". There are two main types of codes: codes to transform a catalytic system of protected gold nanoparticle and a single hydrogen atom into a graph-based representation, and codes to run kernel-based machine learning methods to predict interaction energies between the nanoparticle and the hydrogen atom. This is a snapshot of the code dataset that has been taken on 06.06.2023. A more detailed description of the data and the address to the GitLab repository for the latest version of the code can be found from the parent dataset of this data publication.

Vanadium catalysts for ethylene-norbornene copolymerization
2020
Kopolimery cyklicznych olefin (COCs) stanowią obiecującą grupę materiałów o specyficznych, możliwych do zaprojektowania właściwościach. Szczególnym zainteresowaniem w tej grupie związków cieszą się kopolimery etylenu z norbornenem. Do ich syntezy stosuje się różnorodne kompleksy metali przejściowych, przede wszystkim pierwiastków z grupy 4. Artykuł stanowi przegląd literatury dotyczącej wykorzystania katalizatorów wanadowych z różnego rodzaju ligandami w syntezie kopolimerów etylenu z norbornenem. Opisano wpływ ligandów i warunków prowadzenia reakcji na aktywność oraz wybrane właściwości otrzymanych kopolimerów.
Studies of ethylene/1-hexene copolymerization over zirconocene catalyst supported on MAO-modified MgCl2(THF)2. The effect of copolymerization conditi…
2003
Composition of catalytic system and copolymerization reaction conditions influence on heterogeneity of ethylene/1-hexene copolymers obtained over MgCI2(THF)2/MAO/Cp2ZrCl2/MAO catalyst was studied. One of the DSC techniques, i.e. successive self-nucleation/annealing (SSA) method allowing separation of the polymer into fractions with differing chemical composition in result of alternating crystallization and melting cycles was applied. It was found that the intermolecular heterogeneity exists inside all studied samples irrespective of the reaction conditions (temperature and time) and the catalyst composition (Al/Zr molar ratio). It was also confirmed that catalyst composition has a considera…
MICROBIAL FUEL CELL WITH Ni-Co CATHODE AND KMnO4 CATHOLYTE
2017
The improving standard of living causes the increases in energy consumption and waste or wastewater production. The possibility of combining wastewater treatment and electricity production can be accomplished by means of a microbial fuel cell. The possibility of wastewater treatment using the Ni-Co alloy as cathode catalyst with KMnO4 catholyte for microbial fuel cells was presented in this paper. The measurements covered the comparison of changes in the concentration of COD, NH4+ and NO3- in the reactor without aeration, with aeration and using a microbial fuel cell (with Ni-Co cathode and KMnO4 catholyte). The reduction time for COD using a microbial fuel cell with the Ni-Co catalyst (and…
USE OF Ni-Co ALLOY AS CATHODE CATALYST IN SINGLE CHAMBER MICROBIAL FUEL CELL
2017
Technology of microbial fuel cells allowing for the direct production of electricity from biodegradable materials can provide only energy production, but also wastewater treatment. This technology is seen as supporting of the traditional wastewater treatment. One of the problems with microbial fuel cells is a low current density of those energy sources. Nonetheless, it is possible to increase the current density by using the catalyst for electrodes (anode and cathode). The possibility of wastewater treatment using the Ni-Co alloy as catalyst for single chamber microbial fuel cells is presented in this paper. The studies have included measurements of H2O2 reduction on Ni-Co catalyst, power o…
State of the art and prospects for halide perovskite nanocrystals
2021
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics and photocatalysis. The ease with which metal-halide perovskites can be synthesized in the form of brightly luminescent colloidal nanocrystals, as well as their tunable and intriguing optical and electronic properties, has attracted researchers from different disciplines of science and technology. In the last few years, there has been a significant progress in the shape-controlled synthesis of …
A systematic literature review of the transition to the circular economy in business organizations: Obstacles, catalysts and ambivalences
2021
There is a need for a transition from unsustainable linear business models to a more sustainable circular approach, called the circular economy. To promote this need, a deeper understanding of which issues hinder organizations’ transition to the circular economy and which ones catalyse it is needed. A systematic literature review was performed on the business implementation of the circular economy and 69 articles covering the topic were found. The review identifies different types of catalyst, obstacles and ambivalent factors influencing circular economy implementation in business. This study contributes to research on circular economy implementation at business organizations by providing u…
Badanie aktywności katalizatorów Ni-Al2O3 w procesie uwodornienia kwasu maleinowego
2016
Zbadano wpływ zawartości aluminium na aktywność katalizatorów Ni-Al2O3 w procesie uwodornienia kwasu maleinowego. Aktywność katalityczną mierzono metodą potencjometryczną. Najwyższą aktywność katalityczną wykazywał katalizator zawierający 1% mol. Al. Stwierdzono obniżenie aktywności badanych katalizatorów ze wzrostem temperatury procesu uwodornienia.
Evaluation of the concept of heterology in a monoclonal antibody-based ELISA utilizing direct hapten linkage to polystyrene microtiter plates.
2005
A series of new heterologous haptens has been synthesized and used as coating haptens in an antigen-immobilized immunoassay with a monoclonal antibody against atrazine. Coating was achieved by covalently linking the different haptens to a glutaraldehyde network directly bound to the polystyrene surface of a standard 96-well microtiter plate. With the assay designed in the antigen-immobilized format with direct chemical linkage of the hapten to the solid polystyrene surface well-defined hapten densities were achieved in all experiments. The results of different experiments with different coating haptens were comparable. Using different heterologous haptens it appears that the concept of hete…
