This study aims to determine whether there is an effect of Current Ratio (CR), Total Asset Turnover (TATO), and Net Profit Margin (NPM) on profit growth at PT HM Sampoerna Tbk on the Indonesia Stock Exchange in 2017-2021. This type of research is quantitative, while the data used is secondary data obtained from the financial statements of PT HM ...

Synthesis and characterization of acidic properties of Al-HMS materials of varying Si/Al ratios
Thermochimica Acta, 2006HMS and Al-HMS materials with Si/Al ratio in the range 5–45 were synthesized by neutral templating pathway. The as synthesized as well as calcined samples were examined for pore size distribution, surface area and XRD. These investigations confirmed the hexagonal mesoporous structure formation at all Si/Al ratios.

Copper-containing mesoporous Al-HMS catalysts prepared via the deposition−precipitation method have been found to be highly efficient in the catalytic hydrogenation of dimethyl oxalate (DMO) to ethylene glycohol (EG). Besides the Al chemical environment, the Si/Al ratios of the mesoporous support show remarkable effect on the catalytic performance. The

10th International Conference on Nuclear Engineering, Volume 4, 2002
Calculations were performed using MOCUP, which includes the use of MCNP for neutron transport and ORIGEN for depletion. The MOCUP calculations were done using a unit cell (pin cell) model, where the ThO2 varied from 65–75wt% and the UO2 varied from 25–35wt%. The fission products and actinides being tracked in the calculations account for >97% of

ABSTRACTNi‐W/HZSM5‐HMS catalysts were evaluated for the benzene hydrogenation reaction at 130–190°C. To study the catalyst characterization, X‐ray diffraction, X‐ray fluorescence, Fourier transform infrared, UV–vis, diffuse reflectance spectra, temperature‐programmed desorption of NH3, FT‐IR of adsorbed pyridine measurements (Py‐IR), H2 chemisorption ...

Abstract In this work, the primary amine template has been extracted from freshly synthesized hexagonal mesoporous silica (HMS) materials by means of modified supercritical carbon dioxide at 60–85 °C under 10.0–20.0 MPa. The influences of amine identity and matrix Al/Si ratio on the extraction efficiencies and structural properties of HMS thus ...

The complexation of oppositely charged polyelectrolytes leads to Polyelectrolyte Complexes (PECs). PECs can exist in many different states, depending on the architecture of the polymers and the environmental parameters of the solution. Using double hydrophilic block copolymers (DHBCs), PECs can be stabilized as dispersed aggregates in solutions ...
