Summary: This research studied the mechanical and shape recovery characteristics of thermal-responsive shape-memory polyurethane (SMPU) reinforced with two types of reinforcements, multiwalled carbon nanotubes (MWCNTs) and halloysite nanotubes (HNTs). Composite specimens with different weight percentages (0, 0.5, and 1%) of reinforcements in the SMPU matrix were obtained through injection moulding. Tensile, flexural, impact, and shape recovery behaviors were experimentally studied, and the concentration of both reinforcements significantly improved mechanical properties and shape recovery.

Summary: In this study, we report in situ measurements of the electrical resistance of a single parallel contact between carbon nanotubes. By varying the contact length, we derive the electrical conductivities of the nanotubes and interfaces. The results show that the interface between carbon nanotubes exhibits a conductivity intermediate between that of pyrolytic and single-crystalline graphite.

Summary: This paper reports on the direct ink writing 3D printing of multifunctional composite materials based on commercial epoxy resin and the recycling of printed composite materials. By adding graphene nanoplatelets as a thixotropic additive, the liquid epoxy resin can be shear-thinning and suitable for direct ink printing. The printed composite materials have high resolution, high mechanical strength, as well as high thermal and electrical conductivity, and fast thermo-induced shape memory response. The printed objects can be recycled by comminuting them into micropowders and used as a thixotropic agent for preparing recycled DIW ink.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

Summary: This study aims to develop a nano-biofungicide comprising of volatile essential oil molecules to enhance its efficacy in the field of agriculture through easily scalable green synthesis technique. The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
