Effect of Bonding Pressure on Thermal Performance of Graphene-enhanced Thermal Interface Materials for Immersion Cooling Applications Graphene, due to its exceptional mechanical, optical, electrical, physical and thermal properties, has attracted strong interest for both fundamental studies and real applications. Among all these properties, the extraordinary high thermal conductivity makes graphene an ideal cooling material for power devices and systems. In mean time, rapid growth of information and AI technology continues to push power density and integration level in electronics devices, leading to an increase in greater heat dissipation causing lower performance, and shorter operating life. In this paper, the technology of a new graphene-enhanced thermal interface material (GT-TIM) manufacturing process is described. The effect of bonding pressures on thermal performance of the GT-TIM with different thicknesses is presented. The immersion test up to 1-month in immersion condition was carried out. The results show that the GT-TIM can be exposed to very high bonding pressure without delamination, well beyond normally used bonding pressure regions and extremely low thermal resistance in the range of 4-5 Kmm2/W at 40 psi (276kPa) at a thickness of 0,2 mm. In a typical biocompatible coolant environment, the thermal performance is basically intact after one month´s exposure. It is thus concluded that that this class of the novel GT-TIM has very interesting feature that can potentially be used for many large power cooling applications, especially for immersion cooling.

Spatial correlations of charge density wave order across the transition in 2H-NbSe2 Charge density waves (CDWs) involve coupled amplitude and phase degrees of freedom, but direct access to local amplitude correlations remains experimentally challenging. Here, we report cryogenic four-dimensional scanning transmission electron microscopy (4D-STEM) measurements of CDW ordering in a 2H-NbSe2 flake of 24 nm thickness, enabled by liquid helium-based cooling. By mapping the spatial distribution of CDW superlattice intensities at nanometer-scale resolution and analyzing their autocorrelations, we extract the temperature-dependent correlation length associated with the local amplitude of the CDW order parameter, independent of global phase coherence. Our results reveal that a finite local CDW amplitude is already established well above the transition temperature. When the system is cooled below the transition temperature down to 20 K, the correlation length extends to nearly 110 nm, and the local CDW amplitude is found to strongly anticorrelate with the local strain field.

Comparative Analysis of Ion Mobility Spectrometry-Based Explosive Trace Detectors Aviation security increasingly relies on explosive trace detectors (ETDs), particularly those employing ion mobility spectrometry (IMS). However, few studies have systematically compared the performance of IMS-based ETDs, especially in terms of measurement uncertainty and stability under repeated operation. This study evaluated two commercially available IMS-based ETDs using statistical analysis and data visualization. Repeated TNT (2,4,6-trinitrotoluene) detection tests were conducted to assess performance over consecutive operations. The results revealed significant differences in measurement uncertainty between the two devices. One ETD exhibited stable measurements throughout, while the other showed variance fluctuations that stabilized only after extended use. Despite using the same detection principle, the two devices responded differently to operational conditions, suggesting that internal specifications and design choices significantly affect reliability. This study offers a methodological framework for ETD comparison and provides insights to support more rigorous evaluation and certification practices in aviation security.

Effects of Changing the Specific Surface Area in the Ceramic Matrix of CAC-Containing Refractory Castables on the Rheology and Processing Besides the coarse and medium grain size distribution, the matrix components play a central role in the performance of refractory castables. Practical experience shows that the particle size distribution (PSD) and the specific surface area (SSA) of the ceramic matrix significantly influence processing, setting, and sintering behaviour. However, there is a lack of systematic studies on how changes in PSD or SSA affect castable properties. This study aims to address this gap by varying ceramic matrices to create model refractory castables with different matrix surface areas. Three dispersing agents with different mechanisms (electrosteric and steric) were used at graded concentrations. Results show that the SSA of the ceramic matrix has a significant influence on the rheological behaviour of refractory castables. A low SSA leads to shear thickening behaviour, a (very) low relative yield stress, and a high slump‑flow. Castables with an intermediate SSA and a multimodal composition show Bingham behaviour with a moderate relative yield stress and low relative viscosity, whereas a high SSA leads to shear thinning behaviour with a (very) high relative yield stress, (very) high relative viscosity, and a low slump-flow. Measurements of the dynamic viscosity of matrix suspensions at very low shear rates correlate with the rheological behaviour of fully composed refractory castables. Regression analysis using the Herschel‑Bulkley model successfully captures the observed qualitative relationships.

Use of Arecanut Agricultural Waste as a High-Value Textile Material in the Circular Textile Design Collection Purpose: This study addresses the growing need for sustainable and circular solutions in the textile industry by exploring the viability of arecanut (Areca catechu) agricultural waste, specifically its husks, as a novel source of natural textile fibre. The research aims to design a collection of textiles using arecanut yarns woven together with cotton and linen yarns to create interesting and innovative textile surfaces. Methodology/Design: Arecanut fibres were extracted through a water retting process and blended with cotton (75:25 ratio) to produce two yarn counts (5s and 10s). These yarns were then woven into fabrics using both powerloom and handloom techniques. Fibre and yarn properties were evaluated using standard testing protocols. Design development was guided by trend analysis and explored through applications in home furnishing and fashion accessories. Findings: The arecanut-cotton blended yarns demonstrated promising physical and mechanical properties for textile use. Fabric samples showcased the unique texture and visual appeal of arecanut fibres, proving their potential for upholstery, scarves, and traditional garments. The results highlight their compatibility with sustainable design approaches, including upcycling and zero-waste processes. Practical and Social Implications: This research promotes a circular economy approach by repurposing agricultural waste into value-added textiles. It also suggests new income opportunities for arecanut farmers and local weavers. Originality: This is the first documented study to investigate the direct application of arecanut fibres in textile development, combining sustainability with design innovation using cotton and linen yarns.

Enhancing the value of oils extracted from coconut processing by-products via enzymatic extraction The extraction of oil from coconut residue (CR) and testa (CT) using cellulasewas studied. By varying the amount of enzyme and extraction time at the enzyme’s optimal pH (pH 5-5.5) and temperature (55-60ºC), the optimised conditions for extracting the oil from CR and CT were 500 U/g CR and 700U/g CT for 4 hrs. The average oil yields from the enzymatic extractions and those from hexane extraction were not statistically different according to the t-test. The properties of CR and CT oils, and oil extracted from coconut milk foulants (FO) reported in previous work were studied. CR, CT and FO had the most comparable properties to those listed in the APCC standard. Compared to virgin coconut oil (VCO), the antioxidant activities of CR and CT oil were similar but FO had ~3 times higher activity. Hence, the oils extracted from CR, CT and coconut milk foulants by cellulase-assisted extraction showed potential as high value products.

Multilayer Radar Absorber Design with Grey Wolf Optimizer: Using Fabricated Literature Materials This study introduces a versatile methodology for the design of multilayer radar absorbing materials (MRAM) using both virtual and experimentally reported materials from the literature. The Grey Wolf Optimizer (GWO) algorithm is utilized to minimize total absorber thickness while maximizing reflection loss across multiple frequency ranges. Initially, 16 virtual materials- derived from previously validated electromagnetic parameters-are used to explore a wide design space. The algorithm's performance is subsequently validated using real materials compiled from the literature. Original MRAM configurations are successfully developed for 2–8 GHz, 8–12 GHz, and 1–20 GHz frequency bands. The designs demonstrated high absorption performance, maintaining reflection losses below –10 dB across 0° to 40° incidence angles under both transverse electric (TE) and transverse magnetic (TM) polarizations. In particular several optimized structures incorporating real materials achieved average reflection losses around –25 dB with total thicknesses below 1.2 mm, outperforming comparable designs in the literature. These findings confirm the effectiveness of GWO in producing compact, broadband, and angularly robust MRAM. The dual-stage approach, combining virtual exploration with real-material validation, highlights the algorithm’s potential for next-generation stealth, EMI shielding, and conformal absorber applications.

Characteristics and evolution of ground substrate in the black soil area of the residual veins of Changbai mountain Background The study of the formation and evolution of black soils holds significant implications for the sustainable utilization of black soil resources and human societal development. However, research exploring the regularity of black soil formation and evolution through surface substrate investigations remains limited. Method This paper, based on the novel concept of “surface substrate layer” proposed by China’s Ministry of Natural Resources, takes the black soils in Fengcheng City and Kuandian County of Dandong City, Liaoning Province, China as the research object. Objective Through integrated analysis of surface substrate classification and geochemical element characterization, this study systematically elucidates the multidimensional controlling mechanisms of parent rock properties on black soil pedogenesis for the first time. Results The results demonstrate pronounced differences in soil characteristics developed from various parent materials. In terms of physical properties: soils formed by the weathering of sedimentary rocks (e.g., carbonate rocks) exhibit finer particle sizes, while soils derived from older metamorphic rocks (e.g., TTG gneiss) have the coarsest particle sizes; soil pH is primarily influenced by parent rock mineral composition, with basic rocks (e.g., basalt) developing acidic soils whereas marble forms neutral soils; soil bulk density correlates with the compactness of parent rocks, with soils developed from Cenozoic basalt exhibiting the highest bulk density. Regarding geochemical characteristics: principal component analysis clearly distinguishes soils developed from different parent rock types, demonstrating their elemental composition inheritance from parent rocks. Chemical index of alteration (CIA) and silica-alumina ratio (Sa) analyses reveal that basic rocks (e.g., Cenozoic basalt) undergo the highest degree of weathering, while metamorphic rocks such as TTG gneiss exhibit the greatest weathering resistance. Beneficial trace elements (e.g., Se, N, P) are generally enriched, but their enrichment levels are closely related to parent rock types. Therefore, lithology of parent rocks serves as the key factor controlling the formation and differentiation of surface substrate properties in the study area’s black soil. Conclusions This understanding holds significant scientific importance for deepening the comprehension of black soil formation and evolution patterns, as well as for implementing precise conservation measures and soil quality improvement based on surface substrate investigation backgrounds.

Real-Time Out-of-Equilibrium Quantum Dynamics in Disordered Materials We report a linear-scaling numerical method for exploring nonequilibrium electron dynamics in systems of arbitrary complexity. Based on the Chebyshev expansion of the time evolution of the single-particle density matrix, the method gives access to nonperturbative excitation and relaxation phenomena in models of disordered materials with sizes on the experimental scale. After validating the method by applying it to saturable optical absorption in clean graphene, we uncover that disorder can enhance absorption in graphene and that the interplay between light, anisotropy, and disorder in nanoporous graphene might be appealing for sensing applications. Beyond the optical properties of graphenelike materials, the method can be applied to a wide range of large-area materials and systems with arbitrary descriptions of defects and disorder.
