Summary: Conjugated porous polymers (CPPs) are a new family of functional porous materials with tuneable porosities and molecular architectures, showing great potentials in adsorption, light harvesting, and catalysis applications. This study describes the incorporation of strong visible-light absorbing BODIPY molecules into the skeleton of CPPs, resulting in CPPs with integrated properties of high surface area, hierarchical porous structures, and strong visible-light absorption. The obtained CPPs demonstrated relatively high adsorption capacity and high photocatalytic degradation efficiency towards organic dyes, with mechanism studies revealing the generation of singlet oxygen species as the main driving force for the dye degradation.

Summary: Dye wastewater from industries is causing serious environmental problems. Adsorption technology has emerged as a promising method for dye wastewater treatment in the past decade. We developed two kinds of magnetic porous adsorbents (HSF and HSVF) with different specific surface areas and activity sites. Both adsorbents showed excellent performance in terms of dye adsorption capacity, especially HSVF. The adsorption kinetics and isotherms were further studied and compared, revealing that introducing strong active sites can improve adsorption capacity and rate. This research highlights the significance of adsorption technology for treating dye wastewater.

Summary: Water pollution requires sustainable materials for green treatment solutions. This study successfully extracted nanocellulose from microalgae through alkaline treatment, bleaching, and hydrolysis without TEMPO-mediated oxidation. The effects of acid concentration on nanocellulose properties were studied and the maximum yield was achieved using sulphuric acid with a concentration of 60%(v/v). The extracted microalgae nanocellulose was incorporated into carboxymethyl cellulose/sodium alginate beads, significantly increasing methylene blue adsorption capacity and achieving a high dye removal percentage.

Summary: In this research, hydroxyapatite powder particles were coated on a Ti-6Al-4V alloy substrate using the plasma spraying method. The study aimed to take advantage of titanium's mechanical properties and hydroxyapatite's biological properties to create bone implants. Preheating the substrate was found to improve adhesion and reduce residual stress, however, it also resulted in the formation of an amorphous phase in the coating, leading to weaker mechanical properties.

Summary: This study investigates the effects of incorporating various types of nanoparticles, both singularly and in hybrid form, on the low-velocity impact (LVI) response of glass fiber reinforced polymer (GFRP) composites. The experimental results reveal that specimens with a single loading of MWCNT or nano-clay have a lower maximum contact force compared to pure specimens with fully rebounding behavior. Furthermore, incorporating more MWCNTs results in stiffer behavior and more brittleness.

Summary: The aim of this study is to investigate the critical buckling force of a sandwich structure with the addition of nanoparticles to composite faces in an acidic environment. The addition of 3 wt% nanoclay shows better performance in improving the durability of the structure against changes in the length and mass of the composite specimens. The immersion in 5% sulfuric acid for 30 days significantly reduces the critical buckling force of composite sandwiches.
