Quenching of the beam-plasma instability by 3-D spectra of large scale density fluctuations [PDF]
A model is presented to explain the highly variable yet low level of Langmuir waves measured in situ by spacecraft when electron beams associated with Type III solar bursts are passing by; the low level of excited waves allows the propagation of such ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Direct preparation of coal–water slurry using coal chemical wastewater represents an economical and feasible approach for wastewater resource utilization. Unlike clean water, however, the complex organic components in wastewater may exert adverse effects on slurry properties.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study presents a comparative evaluation of phosphate adsorption on pristine ZIF‐8 and Fe3O4‐doped ZIF‐8 (Fe3O4/ZIF‐8), a hybrid adsorbent combining high surface area with magnetic separability. Structural integrity and composition were confirmed using SEM, XRD, FTIR, and XPS.

Estudio cinético de la hidrogenación de trans-cinamaldehído sobre catalizadores de Ir/Nb2O5
Revista Facultad de Ingeniería Universidad de Antioquia, 2010 Se estudió la hidrogenación de trans-cinamaldehído sobre catalizadores de Ir/Nb2O5 reducidos en atmósfera de hidrógeno a 473 K (LTR) y a 773 K (HTR). Los catalizadores se caracterizaron por adsorción de N2 a 77 K, quimisorción de H2 a 298 K, TPR y TPD ...

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