Subcritical water is one method of hydrolysis that can convert coconut husk to produce reducing sugars. However, this method has the disadvantage of producing derivative products such as furfural and phenolic compounds that act as inhibitors. One effectiv... see more

Carbon fibre has an increasing demand in application of current technology. The limited supply of current fossil-fuel based precursor from pitch and polyacrylonitrile (PAN) causing the carbon fibre to become expensive. The newest technology is by using li... see more

Waste lignocellulosic biomass obtained from the dry plant matter is the most abundantly available resource for the production of biofuels, and biochar. The invasive weed tree of Prosopis juliflora was employed as feedstock for the extraction process, whic... see more

A mini subcritical nuclear reactor was designed using Monte Carlo methods. The reactor has light water as moderator, natural uranium as fuel, and a 239PuBe neutron source. In the design uranium fuel was modeled in an arrangement of concentric rings: 8.5, ... see more

The solubility of camphene and caryophyllene oxide in subcritical and supercritical carbon dioxide were determined using dynamic off-line analysis method. Under subcritical condition, solubility of camphene and caryophyllene oxide were (1.738 to 18.118) ·... see more

Subcritical water extraction of Tribulus terrestris leaves and fruits was performed at 100 ºC and 60 atm for 30 min. Chemical composition of volatile extracts was investigated.  A simple lactone compound Loliolide (23,82%) was  main components a... see more

This research aims to study the glycerol degradation reaction in subcritical and supercritical water media. The degradation of glycerol into other products was performed both with sulphate salt catalysts and without catalyst. The reactant was made from gl... see more

Degradation of epichlorohydrin was investigated using subcritical water oxidation method in the presence of hydrogen peroxide. Degradation rate was monitored by means of total organic carbon (TOC) analysis. The central composite design was used to determi... see more

Annona muricata (soursop) is a native American plant and is well known for its leafy canopy and its fruits, widely consumed in South America and Southeast Asia. The objective of this work was to obtain Annona muricata leaf extracts and to evaluate their a... see more
