This research aims to investigate and test the feasibility of the production of natural teak sheets and study the appropriate production methods. Study physical properties and mechanical properties to compare with industry standard insulation sheet. The ratio of tattoo and hyacinth. 5% 7% 9% of the material were dried at 400 600 800 kg / m3. The results showed that the modulus rupture. Elastic modulus And thickness swelling. It varies with the amount of glue. The nature of the tattoo causes absorption in the material if the density increases the water absorption will decrease. Compared to standard insulation products. The amount of adhesive is 7% of the weight of the material when dry. The density of 800 kg / m 2 is 25 kg / cm2. 140 degree Celsius ruptured modulus and elastic modulus But the thickness of the swelling has not met the criteria. In the next production should be mixed waterproofing in the work.

In this research scaffolds of β-tricalcium phosphate (β-TCP) and zinc nickel ferrite (ZnxNi1-xFe2O4) were simply fabricated via the uniaxial pressing together with pressureless sintering which can be tailored for specific applications. The morphology of ZnxNi1-xFe2O4/β-TCP scaffolds with all formulas obtained from the SEM result revealed the larger grains the higher porosity and higher interconnectivity with increasing of ZnxNi1-xFe2O4 amount in β-TCP matrix. The high porous structure of the composite scaffold provided high surface area for cell attachment indicative of good cell growth and differentiation. Biological in vitro test using direct contact method with human cells revealed that the composite scaffold of β-TCP and Zn0.8Ni0.2Fe2O4 with all ratios induced the higher growth of Human osteoblast cells and the better cell spreading on surface of specimens

In this work fiber mat based on silk sericin and thunbergia laurifolia linn extract was developed via electrospinning technique for wound dressing application. The waste cocoons were selected from Nakhon Ratchasima 1 (K1) with appropriate spicy for extracting the silk sericin protein. Trunk of thunbergia laurifolia linn was selected for preparing thunbergia laurifolia linn extract. Polyvinyl alcohol (PVA) with several concentrations were chose and fabricated to fibers by electrospinning technique to investigate suitable polymer concentration for mixing silk sericin and thunbergia laurifolia linn extract. The result revealed that PVA of 9 wt % was suitable due to Several parameters were investigated to prepare the electrospun fiber of silk sericin and thunbergia laurifolia linn extract such as their mixing ratio voltage the distance between the needle and the substrate and the needle size. The results indicated that mixing ratio of silk sericin and thunbergia laurifolia linn extract at 50:50 (w/w) voltage of 15 kV the distance of the needle and the substrate at 8 cm and the needle size of 18 were optimum condition for the fabrication of electrospun fiber with diameter of 100-200 nm and that with smooth and continue feature.

Research project on extraction and bioactivity of Xylocarpus granatum extracts. This study aimed to investigate the phytochemicals and antioxidant activities of the X. granatum extract. The fruits of X. granatum was separation by maceration and sequential extraction method with hexane ethyl acetate and methanol to crude extracts. Crude extracts were assessed for their total phenolic contents tested using the Folin–Ciocalteu method and antioxidant activities tested using DPPH radical scavenging assay. The results showed that 1. Phytochemical examination of the extracts of X. granatum included alkaloids condensed tannins phenolic compounds triterpenes steroids cardiac glycosides and anthraquinones. 2 . The crude methanol extract had the highest phenolic content was 96.55 mg GAE /g dw. 3. The crude methanol extract could reduce DPPH; The EC50 was 34 μg/ ml

This research aims to study the properties of local plants Phraek Nam Daeng community for the development of a herbal drink and development drink herbal tea. Local plants used in the study was Khlu (Pluchea indica (L.) Less). The leaves Khlu tested phytochemical composition antioxidant testing by testing their ability to reduce the amount of chemicals 11-diphenyl-2-picrylhydrazyl (DPPH) tests the amount of phenol used Folin-Ciocalteus reagent nutritional analysis and the amount of cellulose and developed the herbal drink tea. The research found that 1. Phytochemical composition of Khlu leaf is mainly flavonoids and tannins anthracnones. 2. Extracted from the leaf extract with methanol showed the ability to reduce the amount of substance 11-Diphenyl-1-picrylhydrazyl (DPPH) was the most abundant. Fresh leaves dried leaves and dried leaves were 30 days values at 131.23 ± 1.42 127.55 ± 1.03 and 125.90 ± 1.28 μg / ml respectively. 3. Extracts from the leaf extract with methanol showed the highest phenolic content as follows: fresh leaves dried leaves and dried leaves for 30 days were 84.91 ± 0.54 82.44 ± 1.09 and 81.01 ± 1.25 mg GAE / g dw respectively. 4. The optimal conditions for the process of making Khlu tea is a temperature of 70 °C for 7 hours. The score of sensory evaluation in terms of appearance color aroma flavor (astringent) and overall were 7.37 ± 1.22 7.23 ± 1.16 6.97. ± 1.30 7.00 ± 1.14 and 7.63 ± 1.10 respectively.
