n support of the National Aeronautics and Space Administration’s (NASA) Human Exploration and Operations Mission Directorate (HEOMD), the Space Launch System (SLS) is being designed for safe, affordable, and sustainable human and scientific exploration missions beyond Earth’s orbit (BEO). The SLS Team is tasked with developing a system capable of safely and repeatedly lofting a new fleet of spa...

The advancement of heat transfer techniques is a challenge to the researcher in this era. Implementation nanotechnology one potential which enhance rate significant amount. Subsequently, can reduce requirement pumping power. However, suspension nanoparticle with liquid produce new working fluid called nanofluid has better thermal and dynamic properties comparison

Physiochemical interactions which occur at the surfaces of oxide materials can significantly impair their performance in many device applications. As a result, surface passivation of oxide materials has been attempted via several deposition methods and with a number of different inert materials. Here, we demonstrate a novel approach to passivate the surface of a versatile semiconducting oxide, ...

Citrus bergamia Risso et Poiteau, also known as "Bergamot," is a plant belonging to the Rutaceae family, defined as a hybrid of bitter orange and lemon. It is an endemic plant of the Calabria region (Italy). Bergamot fruit is primarily used for the extraction of its essential oil (bergamot essential oil: BEO), employed in perfume, cosmetics, food, and confections. The aim of this review was to ...

Building energy optimization (BEO) is a promising technique to achieve efficient designs. The efficacy of algorithms imperative for the BEO and significantly dependent on algorithm hyperparameters. Currently, studies focusing hyperparameters are scarce, common agreement how set their values, especially problems, still lacking. This study proposes metamodel-based methodology hyperparameter appli...

Optical properties such as the dynamic dielectric function, reflectance, and energy-loss function of beryllium oxide (BeO) in its ambient and high-pressure phases are reported for a wide energy range of 0–50 eV. The calculations of optical properties employ first-principles methods based on all-electron density functional theory together with sum over states and finite-field methods. Our result...

The short-time dynamics of amorphous beryllium oxide (a-BeO) has been investigated for electronic excitation/ionization by fast incident electrons, as well as by Ar, Ar, Xe, and Xe ions at velocities of 6% to 10% the speed of light. Site specific Augerelectron spectra induced by fast heavy ions are the central point of this investigation. Electron induced Auger spectra serve as a reference and ...

beryllium  oxide  (beo)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (tl) properties of  the bulk material  in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied  following  irradiation to  the 137 c...
