Adhesive Formulation

A bio-based wood adhesive formulation free of formaldehyde and made from alkali-treated wheat gluten (WG) and sodium alginate (SA) was developed. Its formulation was optimised, and it was characterised by Fourier Transform Infrared (FT-IR) spectroscopy. The bio-adhesive was utilized to make particleboards both with virgin wood particles and recycled wood particles. A dry bio-adhesive content of 35% (w/w) was used to make samples with both type of particles. Single-layer samples of 10 mm thickness were obtained using wood particles of 1 mm (both virgin and recycled). These samples then were subjected to 3-point bending tests. Whereas the bending strength of samples made with recycled wood particles was 18.09 N/m2 and therefore satisfied Type 18 of the Japanese industrial standards (JIS A 5908:2015), the bending strength of the samples made with virgin wood particles was 8.08 N/m2 and satisfied ‘Type 8 Base particleboard Decorative particleboard’ of the Japanese standards. The density of particleboard samples made from recycled wood particles was 916 kg/m3, while that of samples made from virgin wood particles was 732 kg/m3. The alkali-treated WG and SA bio-adhesive has the potential to be used to re-manufacture particleboards, which can then be recycled and not disposed in landfills.

This paper makes use of two trade indicators, Revealed Comparative Advantage (RCA) and Regional Orientation (RO), to evaluate the economic impacts of the ASEAN Free Trade Area (The) and the Regional Comprehensive Economic Partnership (RCEP) on Vietnamese commodities at the Harmonized System (HS) 2-digit level. Several sectors in which Vietnam has revealed a comparative advantage, has benefited from the AFTA, and would continue to enjoy trade creation from the RCEP, are: Cereals (10), Salt, sulphur, earth, stone, plaster, lime and cement (25), Rubber (40), Knitted or crocheted fabric (60), etc. More importantly, the result provides a list of commodities in which Vietnam has a comparative advantage and only experiences trade creation when participating in the RCEP. These are: Milling products, malt, starches, inulin, wheat gluten (11), Vegetable plaiting materials, vegetable products not elsewhere specified (14), Wood and articles of wood, wood charcoal (44), etc. Findings also show commodities in which Vietnam has a comparative advantage; but are not well positioned in the RCEP market yet, e.g. Cereal, flour, starch, milk preparations and products (19) and Manmade staple fibres (55). If sufficient investment decisions and marketing strategies are applied to these commodities, they will well penetrate the RCEP market and bring trade creation and welfare improvement to Vietnam. Public and private investment should consider the above-mentioned commodities as targets to leapfrog the benefits of RCEP.

Dressing Materials

The aim of this paper is to introduce novel dressing with Mikania Micrantha for quick blood clotting and wound healing. When epidermis of human skin is cut or scrapped, sometimes too much bleeding occurs. Excessive bleeding may cause death, if bleeding is not stopped immediately. To promote blood clotting & wound healing natural based bio materials are still insufficient in medical textile sector. To fill up this scarcity, woven fabric treated with Mikania micrantha leaf juice & leaf powder was examined. M. micrantha exhibits good blood clotting time in comparison with available dressing materials. Woven fabric (bandage) that contains M. micrantha can be used for cut wounds healing purpose. The experiments were carried out in environment friendly way which indicates the production & processing of these dressing materials can have enormous contribution to sustainable operations and products.

<a></a><a>As a metal-free conjugated polymer, carbon nitride (CN) has attracted tremendous attention as heterogeneous (photo)catalysts. </a><a></a><a>By following prototype of enzymes, making all catalytic sites of accessible via homogeneous reactions is a promising approach toward maximizing CN activity, but hindered due to </a><a></a><a>the poor insolubility of CN</a>. Herein, we report the dissolution of CN in environment-friendly methane sulfonic acid and the homogeneous photocatalysis driven by CN for the first time with the activity boosted up to 10-times, comparing to the heterogeneous counterparts. Moreover, facile recycling and reusability, the <a>hallmark</a> of heterogeneous catalysts, were kept for the homogeneous CN photocatalyst via reversible precipitation using poor solvents. It opens new vista of CN in homogeneous catalysis and offers a successful example of polymeric catalysts in bridging gaps of homo/heterogeneous catalysis.
