Activated carbon was produced from Cocos nucifera (coconut) fibers by carbonization and activation processes. The sample first pretreated before processes at 450°C 700°C respectively in an electric furnace. Chemical using Potassium hydroxide (KOH) 4:1 (weight basis) carried out to increase the activated adsorption properties. element contained analyzed Energy Dispersive Spectroscopy (EDS) while...

There is a need for sustainable ways of processing plant fibers. Most chemical degumming methods pose threat to the eco-system because presence toxins during disposal. This study aimed find banana fiber with less harm environment. Sodium hydroxide (NaOH) and activated water were utilized softening fiber. Activated an aqueous solution electrolyte strongly oxidizing active substances prepared by ...

We evaluated the effect of dilute sodium hydroxide (NaOH) on wheat straw at boiling temperature for removing lignin and increasing the yield of reducing sugar. Various concentrations of NaOH (0.5% to 2%) were used for pretreating wheat straw at 105 °C for 10 min. Scanning electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy studies revealed that the 2% NaOH-...

Modified by the pretreated model with collagen under the crosslinking effect of glutaraldehyde, the moisture absorption of modified samples increased by 26.34% and 42.6%. The test results of SEM, AFM and DSC show that there was coating on the fibers modified with collagen, and the relative average roughness of the modified fabric decreased. Modification with collagen also affected the thermal p...

Although aramid fiber has the advantage of excellent chemical and mechanical properties, performance composites may be reduced due to low interfacial adhesion between fabric matrix. The surface was modified improve properties. fibers treated with ZnCl2 polydopamine. After pretreated fabrics were made into a composite material by vacuum-assisted resin transfer molding (VARTM) process, their inve...

The present study analyzes the effect of selective deafferentation on the reperfusion injury of the skeletal muscle when nociceptive sensory fibers of the left sciatic nerve are selectively damaged by capsaicin pretreatment in a rat model following tourniquet ischemia (ISC) applied for 30 min, 1 h, and 2 h on the left hind limb. The isometric tetanic contractile force of the extensor digitorum ...

Plant fiber has a complex aggregated structure, high crystallinity and large number of hydrogen bonds, low chemical reaction activity. Therefore, in order to improve the reactivity, plant needs be pretreated before modification. pretreatment method an important influence on modification fibers. In this paper, Jute fibers were successively treated by particular continuous screw-extrusion steam e...

We studied the mechanisms underlying the increase in automaticity induced by a,-adrenergic stimulation of normal and "ischemic" canine Purkinje fibers. Fibers were superfused with a control Tyrode's solution, followed by an ischemic superfusate that included 10 mM KCI, 5 mM NaHCO3, P02 of 10-25 mm Hg, and pH 6.7. To exclude ,B-adrenergic actions, propranolol was added to all solutions. In the p...
