Here, we provide a mini-review on molecular hybrids based on metal oxide hydrates—compounds that readily react with, for example, hydroxylated polymers to form inorganic:organic materials systems with many desirable features and properties. Focusing on titanium oxide hydrates, we discuss here that such molecular hybrids can exhibit a broad refractive index range in addition to an increased glass transition temperature, mechanical stiffness and swelling resistance in comparison to the neat polymer, which illustrates that such hybrid systems offer a new, low-cost, robust and versatile functional materials platform with great promise for, for example, solution-processed photonics, catalysts and antimicrobial coatings. Generally, our mini-review seeks to provide a concise and accessible overview of titanium oxide hydrate:polymer hybrid systems, focusing on their unique properties and processability as well as their broad and largely untapped potential as functional materials. © 2024 The Author(s).

Functionalized halloysite nanotubes ((3-aminopropyl)triethoxysilane acid treated halloysite nanotubes) at different weight percentages (1, 3, 5 and 7 wt%) were loaded with a broad-spectrum antibiotic amoxicillin trihydrate-potassium clavulanate, incorporated into the electrospun membranes, and characterized by different techniques such as XRD, FTIR, SEM, TEM and TGA. Different physical and mechanical properties were evaluated, such as porosity, water uptake, water vapor transmission rate, wettability and tensile properties.

Naturally derived fibers/fillers have gained much attention these days due to their use in the development of renewable and biodegradable components. This research emphasizes the physical, mechanical and tribological aspects of silanized Corchorus olitorius particle‐based thermoset composites. With the help of a contact lay‐up technique, varied weight fractions (0, 2.5, 5, 7.5, 10 and 12.5%)‐based composites as per ASTM standards were generated. The experimental results reveal that silanization promotes the interfacial relationship between particles of Corchorus olitorius and the matrix and also the established silanized particle‐based composites demonstrated a potential modest density feature. The minimal weight fraction‐based composite exhibited the best mechanical and wear‐resistant features. Furthermore, the interval‐valued intuitionistic fuzzy Schweizer–Sklar power weighted average approach has been developed as a distinctive structure for obtaining the most effective composite material for any further industrial applications. From this optimization strategy, the specimen with 5 wt% particle content is found to be the best, followed by the specimen with 7.5 wt% particle content.

Also, biofiber production can stimulate economic growth in rural economies, fueling sustainable development. PLA resins are commonly compounded with biofibers to create biocomposites suitable for additive manufacturing. PLA‐biofiber composites often exhibit better overall material properties than neat (pure) PLA, but the associations between biofiber properties and the material properties of their biocomposites remain largely unexplored. Hence, this research delves into a comprehensive exploration of diverse biofibers, scrutinizing their physical and chemical attributes, including size, shape, ash content and biochemical composition. The study meticulously analyzes the flow properties of each biofiber and elucidates the ultimate tensile strengths and Young's modulus of corresponding biocomposite samples. Noteworthy correlations between biofiber and biocomposite tensile properties are uncovered, shedding light on critical interrelationships. The study introduces an approach employing regression models to predict the ultimate tensile strength and Young's modulus of biocomposites. These models, validated with a cross‐validation technique, exhibit remarkable predictive accuracy, particularly in estimating ultimate tensile strength. © 2024 Oak Ridge National Laboratory managed by UT‐Battelle, LLC and The Author(s).

Hydrodynamic sizes were 164 ± 20.2 and 190 ± 28.2 nm for ZMC and ZMC@Cur, respectively. For both formulations, zeta potential, differential scanning calorimetry, Fourier transform infrared spectroscopy and X‐ray diffraction analyses were conducted. Curcumin encapsulation efficiency was 92%, and its release profile was pH responsive. Using MTT assay, ZMC@Cur demonstrated a significant cytotoxic effect against MCF‐7 and HepG2, surpassing the impact of curcumin. This underscores the pivotal role of ZMC@Cur in enhancing curcumin properties, thereby potentiating cancer cell death. Compared with free curcumin, ZMC@Cur markedly promoted DNA damage in cancer cells, owing to precise curcumin targeting into the nucleus.
