Summary: The variability in biomechanical properties of vetiver roots was mainly influenced by root water content, especially in fine roots. Testing hydrated roots may underestimate strength but overestimate root ductility and underestimate the time of slope failure when considering slope stability.

Summary: This study evaluated the effects of cellulose nanofiber (CNF) addition on the mechanical properties of paper sheets. In the dry state, the Young's modulus and tensile strength increased with increasing CNF addition, but the dry specific Young's modulus remained constant. In the wet state, the wet tensile strength increased linearly with CNF addition up to 50%, followed by a slight decline, while the wet strength retention reached its maximum at 40% CNF addition.

Summary: This study measured the cyclic root mechanical traits and found that cyclic loading had an impact on the root tensile strength and breakage strain. However, the correlation between root diameter and tensile strength and Young's modulus remained unaffected. Hysteresis was observed during cyclic loading, with a significant reduction in hysteresis loop size and peak tensile stress during the first 20 cycles. The peak tensile stress explained a high variability of Young's modulus along the unloading path at all reversal strains.

Summary: The in-plane mechanical behavior of stacks formed by titanium carbide MXenes was investigated in microscale uniaxial tensile experiments. The Young's modulus of MXene stacks remained almost constant, while the tensile strength decreased with an increase in the number of monolayers. The observed dependence of the tensile strength on the number of stacked MXene monolayers was attributed to defects in different layers within the multilayer MXenes.

Summary: This study analyzes the tensile modulus of nanocellulose-reinforced composites and reveals the effects of nanocellulose treatment, radius, and interphase modulus on the relative modulus. The results show that nanocellulose treatment increases the modulus and thickness of the interphase, and the nanocellulose modulus and radius significantly affect the relative modulus, while the interphase modulus only has a significant effect within a certain range.

Summary: Cellulose nanofibrils (CNFs) are promising nanomaterials for food packaging and printed electronics, offering environmentally friendly and cost-effective alternatives to petroleum-based polymers. By combining CNFs with other materials, such as clay minerals, composite materials with superior mechanical properties can be produced using either solvent casting or filtration + hot pressing methods, with the latter showing shorter production times and comparable gas barrier properties to net CNF films.

Summary: The study found that high temperature has a negative impact on the residual mechanical properties of spruce wood, but has a relatively minor effect on stiffness. As the duration of the fire increases and the initial beam cross-section decreases, the residual bending strength decreases as expected.

Summary: Traditional fossil-based plastic usage and disposal pose significant environmental concerns. Poly(lactic acid) (PLA) has gained attention as a safer alternative due to its renewable nature and low environmental cost. This study explores the potential use of orange peel waste in enhancing the PLA matrix.

Summary: In this study, the Ji-developed model was used to predict interphase thickness and modulus of nanocomposites. The model was evaluated for accuracy by comparing it to experimental data. The effects of using compatibilizers or modified nanocellulose on the interphase parameters were also investigated. The results showed that the Ji model improved the prediction of young modulus by considering interphase thickness in nanocomposites.

Summary: This study investigated the impact of 2D WS2 nanoparticles on the conformational changes of lysozyme protein at different pH values, showing that WS2 can both inhibit and stimulate amyloid formation depending on pH and protein concentration. Additionally, an unusual spectroscopic behavior was observed in lysozyme when incubated with 2D WS2 nanoparticles at pH 2.5 and 3.5, indicated by narrowing of Amid I and Amid II bands.

The properties of nanogel and its solid films on various substrates were characterized using nondestructive methods. The results revealed the size and aspect ratio of nanofibrils in both water solutions and solid films, as well as the aggregation behavior of nanofibrils. Optical reflection and photoluminescence methods were found to be applicable for characterizing the nanocellulose.

Summary: The study investigates the cytotoxic effects of two-dimensional tungsten disulfide (2D WS2) water suspension nanoparticles on Lewis lung carcinoma cells and highlights a concentration-dependent decrease in viable cell numbers with prolonged incubation. Raman spectroscopy revealed characteristic bands in treated cells that matched the features of WS2 nanoparticles. The data suggest that the cytotoxicity of 2D WS2 on tumor cells is achieved through its ability to enter or accumulate on the surface of the cells, providing a rationale for further studies on its antitumor efficacy in combination with chemotherapeutic drugs.
