Recycling thermosets have become extremely important due to their ecological and economic benefits. The development of thermosets that undergo reversible polymerization provides a solution to the end-life disposal issue of thermosetting materials. However, the synthesis and recycling of the current chemically recyclable thermosets are harsh, complex, and energyintensive, and their stability is often low. Here, we designed asymmetric acetal-containing thermosets (PRCs) from general phenolic resin and 1,4-cyclohexanedimethanol divinyl ether through one-step "click" cross-linking without using catalysts and solvents and without releasing small-molecule byproducts. PRCs exhibited conspicuous stress relaxation via a dissociative mechanism, corresponding to the superior malleability and reprocess recyclability. Importantly, PRCs presented excellent creep resistance even at 100 °C. In addition, PRCs could be readily and highly efficiently recovered to original phenolic resin via hydrolysis under specific mild acidic conditions but possessed high chemical stability under neutral conditions and even weak acidic conditions or acidic conditions in the absence of organic solvents with outstanding wettability and swellability toward the samples. Thermosets with different properties could be easily achieved via regulating raw materials. This work provides a promising dynamic covalent motif and a practical method to produce readily dual-recyclable (reprocess recyclable and chemically recyclable) thermosets with superior performance and stability.

Polylactide (PLA) is a bio-based polymeric material which is earth abundant in nature. It also possesses abundant strength and stiffness making it a promising material for industrial applications. However, its brittle behavior is currently limiting research work on them. As such, an eco-friendly blending approach is developed in this study in order to fabricate a ductile and toughen PLA composites using renewable bio-based materials as a precursor. Specifically, PLA, epoxidized soybean oil (ESO), and frangible powder form of cellulose nanocrystals (CNCs) are melt blended to prepare the ternary composite system (PLA/CNC/ESO). During the composite routing, it is found out that the ESO successfully attached to the surface of CNC which in turn results in CNC/ESO mixtures in the PLA matrix. This intrinsic combination induces cavitation which consumes the energy produced under the stretching and impacting, resulting in the turning of the PLA's brittle phenomenon. In fact, a reasonable increase in the ductility is observed. The elongation and notched impact strength of the ternary nanocomposite are found to be $32% and $4.8 kJ m −2 , respectively, which are comparatively higher than that of neat PLA or PLA/CNC composites. Differential scanning calorimetry analyses show that the ESO layer on CNC affects the thermal characteristics of PLA in the ternary composite while thermogravimetric analysis shows that there is an increase in the char yield of the composite. Furthermore, scanning electron microscopy analysis shows that the synthesis approach adopted here enables a mechanistically turning of the PLA's brittle phenomenon to ductile.

This study presents the functionalization of organic cotton fabric (OCF) by green synthesized silver nanoparticles (AgNPs). Nontoxic sodium alginate (SA) was utilized as a reducing and stabilizing agent. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), UV–vis spectroscopy, color coordinates, Ag content, and release (%) were used for characterization of the AgNPs and the functionalized OCF. The results reveal that AgNPs were successfully deposited on the surface fibrils of the OCF. Optimistic colors were observed from the treated OCF due to the localized surface plasmon resonance (SPR) of AgNPs. Moreover, studies of mechanical properties in terms of breaking strength and elongation at break (%), crease recovery angle, bending length, and hand-feel were performed, and better results were found in comparison with the control OCF. It was also observed that the presence of AgNPs significantly enhanced the UV resistance and antibacterial activity of the OCF.

'The Tree of Life' or 'Miracle Tree' is the name of the plant of Moringa oleifera (Shajna). Moringa oleifera is one of the important plants in plant kingdom. Its leaves and fruits are used as vegetable in Indian sub continent, at the same time each part of the plant rich with some important medicinal values. It is now considered as a valuable source of several unique products for the medicines against various diseases. The present review is to focus on the nutritive values, physico-chemical properties, phyto-chemicals and pharmacological activities of M. oleifera. Various parts of the plant like seeds, leaves, flowers, bark and fruits have been investigated for their significant pharmacological activity. Phyto-chemicals like flavanoid, anthraquinone, alkaloids, essential oils, tannic acid, carotene, glucose have been reported for significant antioxidant, hepatoprotective, anticancer, aphrodisiac, antiinflammatory, antihyperlipidaemic, antihyperglycaemic and antiulcer activities of Drumstick tree and emphasizes the need for further exploring available information.

Herein, an approach was carried out toward in situ synthesis of chitosan-mediated silver (Ag) nanoparticles (AgNPs) on merino wool fabrics (MWFs) and its utilization as colored textile, antibacterial material and removable substrate after toxic dye reduction. The investigation on the as-produced products (AgNPs@MWFs) indicates that AgNPs were successfully assembled on the MWF surface through efficient interaction between the wool and chitosan terminals with nanoparticles. The AgNPs@MWFs revealed three primary colors (red, yellow and blue) with a brilliant shade due to the localized surface plasmon resonance properties of metal nanoparticles. The colorfastness and color strength (K/S) values were found to be as significant as those of traditional dyes. The tensile properties of the MWFs, such as strength and elongation at break, were measured before and after in situ synthesis of AgNPs and were found improved compared with those of the control samples. The antibacterial performance was also noticed to be excellent with ∼99% bacterial reduction after five consecutive standard washes. Afterward, AgNPs@MWFs coupled with sodium borohydride (NaBH4) were used for azo-containing wastewater treatment. Higher than 90% azo-dye degradation by 30 min was found, which was six times faster than that of the control sample.

Globally, social protection schemes are considered as effective tools in ensuring the well-being of the poor, disempowered and otherwise marginalised people of society. It is applicable in cases of elderly people who are comparatively vulnerable due to their old age, and at times poverty or the lack of financial security.The proportion of elderly people in poverty is higher than that in the working age population, indicating the increasing likelihood of people falling into poverty as they leave or retire from the workforce. Therefore, one way of addressing poverty among the elderly is through social protection mechanisms. Malaysia and the Philippines are two Southeast Asian countries on their way to becoming ageing nations. As such, both these countries have already adopted numerous social protection schemes to ensure the well-being of the marginalised segments of society, including the elderly. Thus, based on existing literature, this paper is an attempt to revisit and re-examine the role and adequacy of existing social protection schemes available in Malaysia and the Philippines.
