The advent of nanotechnology has engineered great interest in synthetic biopolymer-based nanocomposites for use tissue engineering scaffolds, automotives, pharmaceuticals, and so on, due to enhanced mechanical behavior, flexible biodegradation kinetics, biocompatibility. Poly(lactic acid) (PLA), attained from natural materials, exhibit biodegradability, bioabsorbability, with notable demand because inherent versatility applications aforementioned fields. Nevertheless, minimal glass...
A comparative study was performed on the use of esterified alkaline lignin (AAL) and organosolv (AOSL) as interfacial modifying agent to improve properties polypropylene-chitosan composites. Chitosan chemically modified through a reaction with in an alcohol medium. The composites were prepared using internal mixer hot-pressed method. Both chitosan showed different chemical structure upon modification lignins confirmed by Fourier transform infrared spectroscopy spectra. With lower molecular...
Hydrogels (HDG) are materials exhibiting versatile applications in varying fields such as the pharmaceutical and biomedical industries. However, HDG prone to inferior chemical, biological, electrical mechanical features. In order mitigate these deficiencies, advent of nanotechnology has informed inclusion multifunctional nanoparticulates within matrices garnerior superior Thus, polymeric hydrogel nanoarchitectures (PHN) amongst emerging category new nano-hydrogels, fabricated through...
ABSTRACT At present, the rubber toughening of plastics has become an attractive field study in polymer science and technology because brittleness is known to be a drawback many engineering plastics; it can cause premature failure during application. Among existing materials, epoxidized natural (ENR) been widely used as impact modifier or agent large number particular, enhances strength, which deteriorates with incorporation other additives, such fillers flame retardants. ENR modification...
This work examined the effects of filler content and chemical treatment on biodegradation poly(lactic acid) (PLA)/coconut shell (CS) biocomposites in a diastase enzyme-containing buffer medium. CS was treated with two distinct treatments: maleic acid silanation 3-aminopropyltriethoxysilane (3-APE). The incorporated into PLA composites their patterns were studied. Both PLA/CS exhibited lower rates than untreated due to enhanced interfacial adhesion, which reduced area exposed enzyme...
Phycocyanin is a pigment-protein complex synthesized by blue-green microalgae such as Arthrospira (Spirulina) platensis. This pigment used mainly natural colouring in food industry. Previous studies have demonstrated the potential health benefits of this pigment. The price phycocyanin vital factor that dictates its marketability. cost culturing algae, particularly from substrate for growth, one main factors determine phycocyanin. Another important growth yield algae. In our research,...
Corruption is a product of the attitude life group people who use money as standard truth and absolute power. has been going on for long time, since times Ancient Egypt, Babylonia, Rome until Middle Ages now. The purpose this study to determine eradication corruption law enforcement in terms perspective legal philosophy implementing positive Indonesia. This normative research with descriptive method which explains that carried out using primary materials, secondary materials tertiary...
Effects of methyl methacrylate on the properties chitosan-filled polypropylene (PP) composites has been investigated. Mechanical and thermal were analyzed according to ASTM D 638-91, thermogravimetry analysis (TGA) differential scanning calorimetry (DSC). The results showed that tensile strength PP decreased upon addition chitosan, while Young's modulus improved. At a similar filler loading, treated PP/chitosan found have higher as compared with untreated composites. Thermal stability...
Indonesia is one of the countries with largest copper reserves in world, namely Tembagapura area, Mimika Regency, Papua Province. The development electric car technology has a significant impact on increasing demand for copper. This study conducted material engineering materials forging process. aim research was to obtain average energy, strength, and fracture shape from variety materials. variation each test specimen formed following ASTM E23 standard size specification 55 mmL x 10 mmW 8...
Abstract The growing awareness and concern of having greener biodegradable materials has promoted researchers over the world to focus their attention on studies related natural fibre reinforced polymer composites. In this study, mechanical thermal properties coconut shell powder lignin obtained from different extraction methods such as Alkaline Organosolv, epoxy composites were studied. composite was fabricated using hand lay-up method, where fibers 1, 2, 3 4 wt.% mixed with matrix...
The effects of chitosan on properties regenerated cellulose/chitosan (RC/Ch) films were investigated. prepared using a sequence process solution-casting in lithium chloride/N,N-dimethylacetamide ionic liquid, and coagulation water. Due to the amorphous structure formation hydrogen bonding between functional groups both components, tensile strength decreased considerably; however, elongation at break increased. Furthermore, SEM morphology indicated visible separated layers comprising rigid...
