Summary: This study compares the feasibility of using force spectroscopy methods and nanoindentation techniques to obtain elastic properties of shale. It was found that the modulus range in nanoindentation data is larger, but it becomes more difficult to identify organic matter from intermediary phases as thermal maturity increases. In contrast, AFM provides higher resolution modulus maps, allowing for more accurate distinction between different phases.

Summary: This study investigated the effect of water immersion on the epoxy-cement paste interphase using nanoindentation. The results showed that water immersion degraded the nanomechanical properties of epoxy, interphase, and cement paste. The degradation was attributed to plasticization of the epoxy and decalcification processes in the interphase induced by exposure to low-pH water environment.

Summary: The use of precast systems in construction can reduce material wastage, minimize weather impacts, cut costs, decrease reliance on skilled labor, and minimize construction hazards. However, the development of precast substructures or foundation systems for lightweight buildings needs to consider functionality and susceptibility to damage caused by expansive soils. This study assesses the ultimate strength and serviceability of a developed precast concrete wall substructure through laboratory testing and finite element modeling.

Summary: This review summarizes the research conducted so far on cement-based composites reinforced with waste paper-based cellulose fibres, focusing on their composition, mechanical properties, and durability characteristics. The properties of the raw materials significantly affect the formation of the cement composite binders. Silica and magnesium compounds have positive effects on the setting of the cement composite when combined with waste paper cellulose fibres. The dispersion of fibres in the matrix is crucial for developing composites with well-balanced mechanical properties using waste paper cellulose fibres. Water quantity plays a role in improving fibre dispersion, but higher porosity and voids affect the strength properties beyond an optimum water-to-cement ratio.

Summary: The frequencies of time-varying mass systems in engineering structures are rarely studied due to small mass change rates. However, for silos storing granular materials, the mass of the stored granules can be relatively high, resulting in a time-varying mass system during flow-in or flow-out. This study investigates the influence of moisture content ratio on the vibration characteristics of granular materials inside a cylindrical silo using Variational Mode Decomposition, Hilbert Transform, and Hilbert Marginal Spectrum processing methods. The results show that the vibration amplitude and frequency vary with changes in moisture content ratio, indicating variations in the structural loads according to engineering mechanics principles. This research can contribute to the development of a diagnostic tool for conditionally monitoring the structural integrity and flow characteristics of silos.

Summary: The development of corrosion inhibitors with outstanding performance requires continuous efforts from researchers, engineers, and practitioners. This study investigates the electronic features, adsorption characteristics, and bonding mechanisms of two pyridine oximes, 2-pyridylaldoxime (2POH) and 3-pyridylaldoxime (3POH), with an iron surface. The simulations reveal that 3POH exhibits covalent bonding with iron in both its neutral and protonated states, while 2POH only forms bonds in its protonated form. The excellent adsorption properties and corrosion inhibition performance of 3POH can be attributed to its low stability compared to 2POH molecules.

Summary: The revolution of immobilization material has evolved from traditional plaster to modern synthetic casting tape since 3000 BCE, driven by the search for superior casting material with excellent properties in mechanics, load-bearing, non-toxicity, healing rates, patient satisfaction, and eco-friendliness. Traditional plaster remains a popular choice due to skin conformability, low cost, and availability, while synthetic material can cause complications such as compartment syndrome and deep vein thrombosis. This paper provides a comprehensive review on immobilization techniques, existing materials, and associated complications, aiming to assist medical practitioners and researchers in improving and selecting casting materials.

Summary: This study aimed to investigate the potential of Light-transmitting concrete (LTC) in transmitting natural light or sunlight, and explored the relationship between fibre diameter, fibre spacing, solar incidence angle, surface area, and light transmittance properties. The study developed an artificial neural network model and explicit equations to predict the light transmittance of LTC, and found that the incidence angle and surface area had significant effects on light transmittance. Additionally, the effect of these factors was reduced with smaller fibre diameter or larger fibre spacing. The ANN model and equations showed good accuracy in predicting LTC's light transmittance.
