South Kalimantan-Indonesia is in the Southern part of Borneo which almost half population lives remote areas. Geographically, people are isolated and have poor access to electricity as well a clean water supply. It very essential ensure availability produced from peat overcome future shortages. This work performs fabrication multi-channel silica-based membranes applied for ultrafiltration demon...

Membrane-based rapid test reagents including immunochromatography are widely used in clinical practice. Recently, high-sensitive based on the method, such as silver amplification method and time resolved fluorescence for influenza testing, has been developed early confirmation of infection can be achieved. Furthermore, genetic automated all steps from extraction till detection, is getting popul...

A novel free-standing and flexible electrospun carbon-silica composite nanofibrous membrane is newly introduced. The characterization results suggest that the electrospun composite nanofibers are constructed by carbon chains interpenetrated through a linear network of 3-dimensional SiO2. Thermogravimetric analysis indicates that the presence of insulating silica further improve the thermal resi...

Rapid thermal treatments potentially allow for a significant reduction in production time of ceramic multilayered membranes, in turn aiding increased industrial application of these membranes and accelerating research on their development. Two methods are proposed for the rapid thermal treatment of thin supported inorganic membrane films. Both methods involve an instant increment in temperature...

In this study, silica gel was extracted from rice husk ash using a modified acid-leaching process. The then characterized an X-ray Diffractometer (XRD) and Fluorescence (XRF). At different loadings of 0, 0.05 0.10 wt.%, used as cross-linker in the membrane formulation. Fourier Transform Infrared Spectroscopy (FTIR) Scanning Electron Microscopy (SEM) were to characterize membranes, while their p...

In this study, thymol was covalently connected to mesoporous silica nanomaterial by a post-grafting method obtain stable antibacterial system, thus overcoming the volatilization of thymol, prolonging effective time action, and enhancing efficiency thymol. It proposed for first that such synthetic route be adopted synthesize silica-based mesoporous/essential oil materials. The could capable reta...

An aqueous-based microcompartmentalized model involving the integration of partially hydrophobic Fe(III)-rich montmorillonite (FeM) clay particles as structural and catalytic building blocks for colloidosome membrane assembly, self-directed membrane remodeling, and signal-induced protocell communication is described. The clay colloidosomes exhibit size- and charge-selective permeability, and sh...

We have developed for fuel cells a novel proton exchange membrane (PEM) using inorganic phosphotungstic acid (HPW) as proton carrier and mesoporous silica as matrix (HPW-meso-silica) . The proton conductivity measured by electrochemical impedance spectroscopy is 0.11 S cm(-1) at 90 °C and 100% relative humidity (RH) with a low activation energy of ∼14 kJ mol(-1). In order to determine the energ...
