Structural studies of mesoporous ZrO$_{2}$-CeO$_{2}$ and ZrO$_{2}$-CeO$_{2}$/SiO$_{2}$ mixed oxides for catalytical applications [PDF]

open access: yes, 2016
In this work the synthesis of ZrO$_{2}$-CeO$_{2}$ and ZrO$_{2}$-CeO$_{2}$/SiO$_{2}$ were developed, based on the process to form ordered mesoporous materials such as SBA-15 silica.

A computational approach to the theory of adjoints

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2016
The word "adjoint" refers to several definitions which are not all equivalent (see, for example, Greco and Valabrega 1979, 1982): we shall deal with any of them.

Recent Developments in Ceria-Driven Solar Thermochemical Water and Carbon Dioxide Splitting Redox Cycle

open access: yesEnergies, 2023
Metal oxide (MO) based solar thermochemical H2O (WS) and CO2 splitting (CDS) is one of the most promising and potential-containing processes that can be used to produce H2 and syngas (liquid fuel precursor).

Ionic and Electronic Conductivity of Nanostructured, Samaria-Doped Ceria [PDF]

open access: yes, 2012
The ionic and electronic conductivities of samaria doped ceria electrolytes, Ce_(0.85)Sm_(0.15)O_(1.925−δ), with nanometric grain size have been evaluated.

Performance Evaluation of Overcurrent Protection Relay Based on Relay Operation Time (ROT)

open access: yesInternational Journal of Electrical Engineering and Applied Sciences, 2018
Protection system plays an important role in detecting the presence of disorders and may prevent damage that can caused interference. Thus, the reliability of the system to maintain continuity of supply to the load will be improved.

Bar Code vs Janet tree

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
In this paper we study how to compute Janet-multiplicative variables for the elements of a given finite set of terms. A comparison between Bar Codes and the Janet tree defined by Gerdt-Blinkov-Yanovich and reformulated by Seiler is given.

Enhancing the capacity of oxygen carriers for selective oxidations through phase cooperation: Bismuth oxide and ceria-zirconia [PDF]

open access: yes, 2018
Interfacing selective catalysts with oxygen carriers enhances capacity without affecting the surface chemistry, simplifying the design of selective oxygen carriers.

Catalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application [PDF]

open access: yes, 2009
Catalyst layers (4–20 lm) of rhodium (1 wt%) supported on alumina, titania, and ceria–zirconia (Ce0.5Zr0.5O2) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water.

Pengaruh Suhu Sintesis Katalis Partikel Ceria Zirconia terhadap Efektivitas Proses Delignifikasi

open access: yesJurnal Teknik Kimia dan Lingkungan, 2020
Biomass is organic material produced through photosynthetic processes. The presence of lignin on the cell wall will inhibit cellulose to be converted into products. Delignification will open the lignocellulose structure to make cellulose more accessible.
