Sol–Gel Synthesis of Ca2.5Ag0.3Sm0.2Co4O9 Semiconducting Materials for Thermoelectric Applications in Aerospace Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.

Investigation of Iron‐Aluminide‐Like Phase Composition in Complex Concentrated Fe32Cu12Ni11Ti16Al29 Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.

Androgen-independent events in penile development in humans and animals. [PDF]

open access: yes, 2020
The common view on penile development is that it is androgen-dependent, based first and foremost on the fact that the genital tubercle forms a penis in males and a clitoris in females.

Impact of Hot Isostatic Pressing on Microstructure Evolution and Creep Performance of Powder Bed Fusion–Laser Beam Processed CM247LC

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of Hot Isostatic Pressing (HIP) temperature on the microstructure and creep performance of powder bed fusion–laser beam processed CM247LC superalloy is investigated. Grain growth and γ’ precipitate evolution are characterized following HIP at varying temperatures.

Expression of Pro-Apoptotic Bax and Anti-Apoptotic Bcl-2 Proteins in Hydatidiform Moles and Placentas With Hydropic Changes

open access: yesActa Medica Iranica, 2019
Morphologic examination still forms the main diagnostic tool in the differential diagnosis of molar placentas. However the criteria are subjective and show considerable inter-observer variability among pathologists.

Ag Cluster‐Modified K0.5Na0.5NbO3 Piezocatalyst for Enhanced Electrochemical Dinitrogen Reduction Reaction

open access: yesAdvanced Engineering Materials, EarlyView.
Ag cluster‐modified K0.5Na0.5NbO3 acts as an efficient piezocatalyst for electrochemical N2 reduction, enhanced by built‐in electric fields under mechanical actuation. Comparative studies between static and actuated electrodes reveal improved performance under dynamic conditions.
