Summary: The purpose of this research was to evaluate the effectiveness of the microbially induced calcite precipitation (MICP) method in repairing shrinkage cracks. The study found that the addition of bacterial spores successfully healed the cracks, with the specimen containing 1% spores completely sealing the crack within three days. XRD analysis showed that the MICP process promoted the formation of calcite crystals, while SEM/EDS investigation revealed concentrated calcite crystals in certain regions, especially at the top surface of the crack. However, the compressive strength of the specimens decreased due to the addition of nutrients.

Summary: This paper proposes an emotion-based behavioral inhibition and self-repairing memristive circuit that mimics the repair process of the amygdala in the limbic system. The circuit consists of recognition and retention module, damage detection module, repair compensation module, and output module. The circuit enables emotion recognition and behavioral inhibition when recognizing fear through the repair of a damaged amygdala, providing reference for the further development of memristive affective bionic circuits.

Summary: Low molecular weight organogelators, such as phenylboronate alkylglucosides, have found applications in various fields and can form water-sensitive gels. This study focused on the impact of the position of alkyl and phenyl moieties in these structures, and synthesized and studied different counterparts. Rheology and electron microscopy were used to characterize the obtained organogels in toluene and ethyl myristate, and the disruption rates of these gels by water were determined. The results showed that alkylboronate alkylglucosides were not effective gelators, while derivatives with a phenyl ring were good organogelators, although alkylboronates had higher water sensitivities than phenyl counterparts. Therefore, this work expands the scope of glucoside-boronate organogelators and their potential applications in drug delivery systems.

Summary: A simple, practical, and eco-friendly visible light-induced alkylation method for N-sulfonyl ketamine was developed. The method utilized low-cost alkanes and H2O2 as the alkyl sources and oxidant, respectively, without the need for metal, additives, or external photocatalysts. The N-sulfonyl ketamine served as both reactant and photocatalyst, simplifying the reaction system.

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.
