The Role of Psychology in Media During the COVID-19 Pandemic: A Cross-National Study
(Ubiquity Press, 2022-04-07)
Dealing with COVID-19 and with the preventative measures that have been taken to mitigate the transmission of the virus causing the pandemic has posed a great challenge to the population. While psychologists have expertise ...
Use of Temperature Controlled Stage Confocal Raman Microscopy to Study Phase Transition of Lead Dioxide (Plattnerite)
(MDPI, 2020-05-21)
The present work concerns the study of the phase transition of plattnerite [β-PbO2 lead (IV) oxide]-based samples when they are analysed by Raman spectroscopy. The laser-induced degradation process was carried out either ...
Optical fiber interferometer for temperature-independent refractive index measuring over a broad range
(Elsevier, 2021-07)
The present work relates to manufacturing of a simple interferometric optical fiber refractometer that features broad refractive index measuring range without ambiguity. The device consists of a cylindrical polymer cavity ...
Temperature dependence of the rate coefficient of formation of CN radical from C + NH
(Elsevier, 2021-05)
Rate coefficients of the complex-forming C + NHH + CN reaction have been calculated at temperatures ranging from 5 K to 800 K using quasi-classical trajectories on a potential energy surface which accurately describes the ...
Goppa codes over the p-adic integers and integers modulo pe
(Elsevier, 2022-12)
Goppa codes were defined by Valery D. Goppa in 1970. In 1978, Robert J. McEliece used this family of error-correcting codes in his cryptosystem, which has gained popularity in the last decade due to its resistance to attacks ...
Conditioning the volatile stream from biomass fast pyrolysis for the attenuation of steam reforming catalyst deactivation
(Elsevier, 2022-03)
The fast deactivation of the reforming catalyst greatly conditions H2 production from biomass. In order to alleviate this problem, use of conditioning catalysts in a previous conditioning step has been proposed to modify ...
A feasibility study of the installation of a modular bioreactor inside a chemical scrubber at a wastewater treatment plant
(Elsevier, 2021-03)
Chemical scrubbing and biofiltration are well-established technologies for treating contaminated pollutants generated at wastewater treatment plants (WWTPs). Nevertheless, the growing need to reduce the ecological footprint ...
A photovoltaic forced ventilated façade (PV-FVF) as heat source for a heat pump: Assessing its energetical profit in nZEB buildings
(Elsevier, 2022-04)
The European Union is changing its energy model towards a more efficient and sustainable one. In this new outlook, the Heat Pump (HP) has become a leading technology in the building energy sector. The use of the air source ...
3D printed alginate-cellulose nanofibers based patches for local curcumin administration
(Elsevier, 2021-07)
Alginate and nanocellulose are potential biomaterials to be employed as bioinks for three-dimensional (3D) printing. Alginate-cellulose nanofibers (A-CNF) formulations with CNF amounts up to 5 wt% were developed and ...
Role of zeolite properties in bio-oil deoxygenation and hydrocarbons production by catalytic cracking
(Elsevier, 2022-03)
A comparison between the behavior of Y and ZSM-5 zeolites having the same Si/Al ratio was established in the catalytic cracking of bio-oil for producing fuels and platform chemicals. The catalysts were prepared by agglomerating ...
