Abstract: Xerogel is a typical porous material with large internal surface area, causing them to have significant gas adsorption. Adsorption performance was investigated determine the potential contribution of xerogel removing Hydrogen Sulphide (H2S) in this research. well-known energy-efficient approach for acid gases at low temperatures. H2S harms human health, such as headaches, eye irritati...

Titanium dioxide nano-particles were synthesized via the sol-gel method using titanium butoxide as the precursor. Acid catalyzed and aged gels were dried under air to produce xerogels and under supercritical conditions to produce aerogels. Porous particles obtained were characterized using X-ray diffraction, SEM and BET analysis. Aerogel powder was found to have more favorable properties compar...

Abstract N-, Ni-, and graphene oxide (GO)-doped carbon xerogel were synthesized from melamine-resorcinol-formaldehyde gels by drying followed pyrolysis at 950 °C. The mass of nickel GO in xerogel, formed after carbonization was 5 1%, respectively. obtained product characterized scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD) Fourier transform in...

Kualitas dispersi bahan pengisi dalam karet sangat mempengaruhi sifat fisis dari vulkanisat karet. Metode baku pengujian silika (ISO 11345-2006) merupakan metode kualitatif sehingga hasilnya bersifat subyektif. Tujuan penelitian ini adalah menguji yang penggabungan mikroskop optik dan perangkat lunak ImageJ untuk mendapatkan secara kuantitatif. Alat dipergunakan mengevaluasi yaitu Arcs. Karet a...

The approach of the atomic pair distribution function (PDF) technique to study the structure of nanocrystalline materials is considered and successfully applied to V2O5.nH2O xerogel and Cs intercalated inside the pores of the zeolite ITQ-4. We find that V2O5.nH2O is an assembly of almost perfect bi-layers of VO5 units encapsulating the water molecules. Inside the nanopores of ITQ-4 the cesium i...
