The Combination of Direct Aging and Cryogenic Treatment Effectively Enhances the Mechanical Properties of 18Ni300 by Selective Laser Melting by Yaling Zhang, Xia Chen, Bo Qu, Yao Tao, Wei Zeng, Bin Chen

“…TEM observations revealed that cryogenic treatment refined lath martensite from 0.75 μm (AT6) to 0.24 μm (AT6C8) and transformed reversed austenite into thin linear structures at the martensite boundaries. The combination of direct aging and cryogenic treatment effectively enhances the mechanical properties of SLM-fabricated 18Ni300 maraging steel through martensite transformation, microstructural refinement, and increased dislocation density. …”

Regionalization Analysis of Environmental Drivers of CONUS Grazing Land Biomass by Jisung Geba Chang, Feng Gao, Martha C. Anderson, Richard Cirone, Haoteng Zhao

“…However, the incorporation of adaptive modeling through clustering did not yield a significant improvement in the accuracy of the random forest model likely due to its inherent capability to capture regional variations through complex decision tree structures. In contrast, the multiple-linear-regression model demonstrated a substantial improvement of around 16%, with the <italic>R</italic>² value increasing from 0.388 to 0.556. …”

Feeding niches drive different responses to plant defenses in two closely related species of classical biological control herbivores by Jasleen Kaur, Lucia Navia, Emily Kraus, Octavio Menocal, Philip G. Hahn

“…This study explored the interactions between two congeneric specialist herbivores introduced to control Dioscorea bulbifera (air potato) in Florida, USA: Lilioceris cheni (Coleoptera: Chrysomelidae), primarily a leaf feeder, and L. egena, primarily a bulbil (aerial reproductive structures) feeder. We examined whether foliar herbivory by L. cheni or induced defenses by jasmonic acid (JA) or salicylic acid (SA) influenced L. egena’s feeding behavior and performance on bulbils. …”

Catalyzed biochar from date palm waste for ammonium removal: potential application in poultry farms for ammonia mitigation by Shymaa Saad Sayed Ibrahim, Yossry Bayoumy Abd-Elhay, Mohamed Mustafa Elkoly, Ahmed El-Raie Emam Suliman, Badr Ali Mohamed

“…Scanning electron microscope (SEM) analysis showed that the biochar without catalysts has a rough surface and pores of varying sizes, resulting in a relatively high specific surface area (39.52 m2/g), a critical feature for sorbent materials, and the interior of the biochar had evident, homogenous pores that formed cylinder-shaped structures. The findings of Fourier transformation infrared (FTIR) analysis conclude that biochar shows oxygen-functional groups (i.e., ‒OH and C‒O‒C). …”

Application of the method of insignificant divergences to diagnose the technical aircraft gas turbine engine state under the transient-state conditions of its operation by O. F. Mashoshin, I. G. Kharmats

“…It is shown that, despite the structural similarity of linear models of the steady and transient-state processes, diagnostics by means of the stated above processes is based on completely different principles – under the steady-state condition, the classification of a technical condition is determined by the variation in the value of the group of controlled responses, and under the transient-state condition, this operation is based on correlating the change in the transient-state behavior. …”
