A highly active and stable Sr2Fe1.5Mo0.5O6-δ-Ce0.8Sm0.2O1.95 ceramic fuel electrode for efficient hydrogen production via a steam electrolyzer without safe gas

open access: yesInternational Journal of Coal Science & Technology, 2022
High temperature steam (H2O) electrolysis via a solid oxide electrolysis cell is an efficient way to produce hydrogen (H2) because of its high energy conversion efficiency as well as simple and green process, especially when the electrolysis process is ...

Transients in Input and Output Signals in DC–DC Converters Working in Maximum Power Point Tracking Systems

open access: yesEnergies, 2023
Designing a maximum power point tracking system (MPPT) can raise many questions when it comes to choosing the best converter and algorithm for the job. The number of possible solutions can be overwhelming, especially when it comes to MPPT algorithms. New

Simulation of surface deformation control during selective laser melting of AlSi10Mg powder using an external magnetic field

open access: yesAIP Advances, 2019
Selective laser melting (SLM) produces complex physical behaviors. After laser melting, the molten pool condenses with an uneven surface, which influences the next powder spreading process and affects the quality of the final product.

Further Improvements in Topological Transformer Model Covering Core Saturation

open access: yesIEEE Access, 2022
This paper is devoted to improvements of the low-frequency topological model of a three-legged stacked-core transformer. It is shown that $B-H$ hysteresis loops employed in the transformer model and $\Psi -i$ curves measured at transformer terminals ...

Transient leukemia

open access: yesIndian Journal of Pathology and Microbiology, 2009
A new born with a mongoloid slant, brachycephaly and low-set ears presented at birth with a total leucocyte count of 57 x 10(3)/microL and the differential leucocyte count revealed 70% of these to be blasts. The morphology of the blasts was not characteristic of myeloid and lymphoid lineage.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
