The asymmetric unit of the title compound, C13H10N2O2, contains two crystallographically independent mol-ecules (A and B). The indazole ring systems are approximately planar [maximum deviations = 0.0037 (15) and -0.0198 (15) Å], and their mean planes are oriented at 80.10 (5) and 65.97 (4)° with respect to the furan rings in mol-ecules A and B, respectively. In the crystal, pairs of C-H⋯N hydrogen bonds link the B mol-ecules, forming inversion dimers. These dimers are bridged by the A mol-ecules via C-H⋯O hydrogen bonds, forming sheets parallel to (011). There are also C-H⋯π inter-actions present, and π-π inter-actions between neighbouring furan and the indazole rings [centroid-centroid distance = 3.8708 (9) Å] of inversion-related mol-ecules, forming a three-dimensional structure.

Microplastics (MPs) in nature inevitably undergo various aging processes and may exhibit varied interfacial interactions with the coexisted contaminants. Here several discarded disposable polyethylene and polypropylene plastic packaging materials were collected and employed as the raw materials of MPs, and the effects of stimulated UV irradiation and microbial colonization on the variations of surface physicochemical characteristics, including biofilm content, oxygen-containing functional groups, oxygen/carbon ratio, hydrophilicity and surface charge properties were explored. Simultaneously, the adsorption behavior of each MPs on the representative cationic dye crystal violet (CV), as well as the influences of salinity and pH of CV solution, was investigated.

The development and modification of grouting materials constitute crucial factors influencing the effectiveness of grouting. Given the pivotal role of water in the hydration of cement-based composite materials and construction processes, this study proposes an exploratory approach using green, economical magnetized water technology to enhance the performance of cement grouts. The research systematically investigates the effects of magnetized water on the fundamental grouting properties (stability, rheological behavior, and stone body strength) of cement grouts, prepared under varying magnetization conditions (including magnetic intensity, water flow speed, and cycle times).

Minimizing the oxidation of lipids remains one of the most important challenges to extend the shelf-life of food products and reduce food waste. While most consumer products contain antioxidants, the most efficient strategy is to incorporate combinations of two or more compounds, boosting the total antioxidant capacity. Unfortunately, the reasons for observing synergistic / antagonistic / additive effects in food samples are still unclear, and it is common to observe very different responses even for similar mixtures.

High-entropy metal-organic frameworks (HE-MOFs) hold promise as versatile materials, yet current rare examples are confined to low-valence elements in the fourth period, constraining their design and optimization for diverse applications. Here, a novel high-entropy, defect-rich and small-sized (32 nm) UiO-66 (ZrHfCeSnTi HE-UiO-66) has been synthesized for the first time, leveraging increased configurational entropy to achieve high tolerance to doping with diverse metal ions. The lattice distortion of HE-UiO-66 induces high exposure of metal nodes to create coordination unsaturated metal sites with a concentration of 322.
