Abstract The SOLARIS synchrotron located in Krakow, Poland, is a third-generation light source operating at medium electron energy. first was observed 2015, and the consequent development of infrastructure lead to users’ experiments soft X-ray energies 2018. Presently, expands its operation towards hard X-rays with continuous developments beamlines concurrent infrastructure. In following, we will summarize design, describe research together main performance parameters, upgrade, plans.
Hydrogen generation by photoreforming of methanol is being one the most intensely investigated photochemical transformations in pursuing a sustainable, zero waste circular economy. This transformation usually produces significant amount gaseous carbon form CO2 and CO that disqualifies many active photocatalysts as fully sustainable. Here, we demonstrate atomically dispersed Cu on TiO2 composite nanoparticles synthesized wet impregnation method are highly selective hydrogen production...
Novel functionalized nanoparticles, with toxicity controlled by laser irradiation, are perspective agents for potential (MRI)-guided stimulated chemo-photothermal treatment of cancer.
Abstract The novel iron-oxide nanoparticles (NPs) stabilized with triethanolammonium oleate were produced. specimens divided into two groups: the top NPs (extracted from supernatant) and bottom (nanoparticles sedimented at of flask during centrifugation), respectively. XRD Mössbauer studies revealed a presence Fe 3 O 4 phase in both types nanoparticles. Furthermore, formation maghemite layer on surface was observed. Average particle sizes determined TEM lower than superparamagnetic limit for...
Abstract Phase formation by pulsed laser irradiation of suspended nanoparticles has recently been introduced as a promising synthesis technique for heterostructures. The main challenge still lingers regarding the exact mechanism particle due to non‐equilibrium kinetic by‐products resulting from localized alternative, fast, high‐temperature nature process. Here, authors analyze bond breaking/formation copper or (II) interfaces with ethanol during absorption pulses Cu‐CuO‐Cu 2 O applicable an...
Structural behavior of Ca 10 Ni 0.5 (VO 4 ) 7 under low temperature and high pressure conditions: lattice parameters, thermal expansion, compressibility analysis.
Airborne fine particulate matter (PM2.5) pollution decreased during last decade in Krakow, Poland. X-Ray Absorption Near Edge Structure (XANES) technique at ASTRA beamline of SOLARIS Synchrotron (Krakow, Poland) has been used to study 8 aerosol samples collected Krakow summer and winter 2018/2019 2020/2021 K absorption edges sulphur, chlorine, potassium, iron zinc. Samples PM2.5 contain sulphur mostly as sulphates. On the other hand, additionally bisulphates, sulphides organic sulphur. KHSO4...
In this study, we present a complex approach for increasing light utilisation and peroxymonosulfate (PMS) activation in BiVO4-based photocatalyst. This involves two key considerations: the design of precursor BiVO4 synthesis interface engineering through CuOx sub-nanoclusters deposition. The designed ammonium methavanadate (NH4VO3, NHV) leads to reduction particle size, better dispersion improved harvesting ability, confirmed by calculations local volume rate photon absorption (LVRPA) using...
Abstract In this work, a family of Ni‐based dibenzotetraaza[14]annulene (dtaa) complexes are investigated for their application in memristors (memory resistors). A series four Ni(II) with different peripheral substituents the dtaa ligand successfully synthesized. Based on these compounds, two‐terminal thin‐film devices fabricated planar architecture. Four metals work functions tested: Mg, Cu, Ni, and Au. It is demonstrated that ITO|[Ni(Me 4 dtaa)]|Cu show hysteretic behavior offer stable,...
This work evaluates partially amorphous La0.6Sr0.4CoO3-δ (LSC) as a potential oxygen electrode for low-temperature solid oxide cells. LSC was deposited using the spin-coating technique onto Ce0.8Gd0.2O2-δ (CGO) substrates. The optimal thickness determined 500 nm. electrochemical impedance spectroscopy (EIS) study showed significant improvement in reduction/oxidation reaction kinetics when annealing temperatures below 600 °C. lowest value of polarisation resistance observed sample annealed at...
Cyanothiazoles, small and quite overlooked molecules, possess remarkable optical properties that can be fine‐tuned through coordination with transition metals. In this study, we investigate a promising application of cyanothiazoles, where their combination copper(I) iodide forms new class complexes exhibiting outstanding properties. X‐ray crystallography isomeric cyanothiazoles revealed key structural features, such as π‐π stacking, hydrogen bonding, rare halogen‐‐‐chalcogen I‐‐‐S...
XANES spectra of sulphur compounds measured at ASTRA beamline (SOLARIS) support a growing reference library for biological research, enabling detailed insights into sulphur’s roles in medicine, biotech, and environmental studies.
The influence of La- or Nb-doping was studied for the phase transition Sr 2 Fe 1.5 Mo 0.5 O 6−δ . Niobium does not have a positive impact on stability and properties, while La enhances electrical conductivity double perovskites.
Thiazolothiazoles (TzTzs) are planar, π‐conjugated heterocyclic compounds exhibiting unique structural and optoelectronic properties.
