CO2 Adsorption on Mesoporous Silica Using Response Surface Methodology (RSM)

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The aim of the current study is to investigate the CO2 adsorption on the mesoporous silica. The adsorbent was characterized by XRD, TEM, SEM, and N2 adsorption desorption. The adsorption isotherms of carbon dioxide (CO2) on the silica were investigated using a static volumetric method at various temperatures.

Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...

First‐Principles Investigation of the Thermoelectric Behavior of the Orthorhombic Cadmium Stannate (Cd2SnO4)

open access: yesAdvanced Physics Research, EarlyView.
Cd2SnO4 exhibits excellent thermoelectric properties with a high Seebeck coefficient, power factor, and figure of merit, surpassing Bi2Te3. It shows both positive and negative Seebeck coefficient values, making it suitable for diverse applications. Its high electrical conductivity and low thermal conductivity enhance efficiency, while its negative Hall

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.
