We have developed apparatus to assess spinnability that uses an impedance to prevent of electrolysis. The spinning distance and the stress confirmed by measurement of dial gauge. A total of 10 starch pastes was prepared from corn, sago, katakuri, sweet potato, kuzu, edible canna, cassava, Indian lotus root, bracken, and potato, at 2% and 4% concentrations. The spinning distance of each starch paste showed a dependence on the concentration and the tensile velocity. The strain at the point of maximum stress increased in all samples with increases in the tensile velocity. The spinning energy increased with increase in the tensile velocity, with a particularly large dependence on the tensile velocity of potato. Cluster analysis was done using the spinning property values of 4% starch pastes as the parameters, which showed a division at a distance of 20, yielding four clusters, with each cluster showing a distinctive spinning pattern.

Hot dry rock (HDR) is a novel green, low-carbon energy. Its development requires the creation of fracture channels in deep thermal reservoirs. Traditional methods such as hydraulic fracturing have limited effectiveness in reservoir stimulation, so a method of liquid nitrogen cold shock was proposed.

Geopolymer concrete (GPC) offers a sustainable alternative by eliminating the need for cement, thereby reducing carbon dioxide emissions. Using durable concrete helps prevent the corrosion of reinforcing bars and reduces spalling caused by chemical attacks. This study investigates the impact of adding 5, 10, and 15% silica fumes (SF) on the mechanical and durability properties of GPC cured at 60 °C for 24 h.

This study investigates the effects of incorporating wood dust particles on the mechanical and erosive wear properties of Luffa acutangula fiber (LAF)-reinforced phenol-formaldehyde composites, fabricated using the hand layup method with a constant 20% fiber content and varying wood dust particle contents of 0%, 10%, 20%, and 30%. Using the Taguchi method, the study identifies the optimal combination for minimizing erosive wear - 20% wood dust content, 45 m/s impact velocity, 60° impingement angle, 600 μm erodent size, and 60 mm standoff distance-achieving a minimum erosion rate of 189.

High-pressure die casting (HPDC) of aluminum alloys is one of the most efficient manufacturing methods, offering high repeatability and the ability to produce highly complex castings. The cast parts are characterized by good surface quality, high dimensional accuracy, and high tensile strength. Continuous technological advancements are driving the increase in part complexity and quality requirements.

This study investigated both the static and dynamic behavior of silicate materials through a series of experimental and numerical tests. Compression tests were conducted on cubic samples, three-point bending tests on beams, and perforation tests on silicate plates. In the compression tests, stress-strain curves were generated, enabling the calibration of the Concrete Damaged Plasticity (CDP) model for silicate materials.
