Abstract Microbial polysaccharides, due to their unique physicochemical properties, have been shown to effectively enhance the stability of foam fracturing fluids. However, the combined application of microbial polysaccharides and surfactants under high-temperature and high-salinity conditions remain poorly understood. In this study, we innovatively investigate this problem with a particular focus on foam stabilization mechanisms. By employing the Waring blender method, the optimal surfactant-microbial polysaccharide blends are identified, and the foam stability, rheological properties, and decay behavior in different systems under varying conditions are systematically analyzed for the first time. The results reveal that microbial polysaccharides significantly More >

Abstract Tannins are polyphenols widely present in the plant kingdom, commonly divided into two groups: condensed and hydrolysable tannins. Sustainable furanic bio-foams based on condensed tannins have been largely studied, but little is described about the use of hydrolysable tannins for this material. This study examined the potential of hydrolysable chestnut tannin in comparison to condensed mimosa tannins to produce furanic foams by chemical expansion. Due to the low reactivity of the hydrolysable tannin, the use of an external source for its polymerization and curing was necessary. Through Fourier transform infrared spectroscopy (FTIR) chromatography, it was More > Graphic Abstract

Abstract Natural rubber (NR) foams are widely used. However, further studies are required for preparing eco-friendly NR foam and determining the optimum physical properties appropriate for application. This study aims to create an NR foam from rubber reinforced with sugarcane bagasse ash (SCBA) and sodium alginate. The results showed that the SCBA was primarily composed of silica or silicon dioxide (87.52% by weight) and carbon (11.41% by weight). This study investigated the influence of the amount of sodium alginate (0–5 phr) used in the NR foam formation. The addition of SCBA on the NR foam affected More > Graphic Abstract

Abstract In recent years, degradable materials to replace petroleum-based materials in preparing high-performance foams have received much research attention. Degradable polymer foaming mostly uses supercritical fluids, especially carbon dioxide (Sc-CO₂). The main reason is that the foams obtained by Sc-CO₂ foaming have excellent performance, and the foaming agent is green and pollution-free. In current research, Poly (butylene adipate-co-terephthalate) (PBAT), poly (lactic acid) (PLA), and other degradable polymers are generally used as the main foaming materials, but the foaming performance of these degradable polyesters is poor and requires modification. In this work, 10% PLA was added to PBAT to… More > Graphic Abstract

Abstract In this study, two series of foams based on tannic acid (TA), furfuryl alcohol (FA), soybean protein isolate (SPI), and casein (CA), namely TA–FA–SPI (TS series) and TA–FA–CA (TC series) were developed, and their properties were enhanced by adding poplar fibers (WF). From the samples produced, a complete set of characterization was performed including possible crosslinking reactions, morphology, mechanical properties, flame retardancy, thermal insulation and thermal stability. Fourier-transform infrared spectroscopy (FTIR) revealed possible covalent crosslinking among the components and hydrogen bonding between WF and the matrix. Viscosity results indicated that lower prepolymer viscosity led to… More >

Abstract This work explores the development of biodegradable laminar composite foams for cushioning applications. The focus lies on overcoming the inherent brittleness of starch foams by incorporating various paper types as reinforcement. Tapioca starch and glutinous starch were blended in varying ratios (100:0–0:100) to optimize the base material’s properties. The morphology, density, flexural strength, and impact strength of these starch blends were evaluated. The results revealed a trade-off between impact strength and density, with increasing glutinous starch content favoring impact resistance but also leading to higher density. The optimal ratio of tapioca to glutinous starch for… More > Graphic Abstract

Abstract This study investigated the development of mycelium-based biofoams as sustainable cushioning materials using Pleurotus ostreatus and Lentinus squarrosulus, combined with different sawdust substrates, and subjected to various pressing methods. The results indicated significant effects of mushroom species, sawdust type, and pressing method on the properties of biofoams. Growth rate, morphology, chemical composition, physical and mechanical properties, water resistance, and cushioning factor were evaluated. The results indicated that Lentinus squarrosulus (LS) exhibited faster growth rates (up to 14.37 mm/day) and produced biofoams with superior properties compared to Pleurotus ostreatus (PO). Core wood (CW) sawdust generally resulted in biofoams with lower… More > Graphic Abstract

Abstract Background: Dihydrolipoamide S-acetyltransferase (DLAT) is a subunit of the pyruvate dehydrogenase complex (PDC), a rate-limiting enzyme complex, that can participate in either glycolysis or the tricarboxylic acid cycle (TCA). However, the pathogenesis is not fully understood. We aimed to perform a more systematic and comprehensive analysis of DLAT in the occurrence and progression of tumors, and to investigate its function in patients’ prognosis and immunotherapy. Methods: The differential expression, diagnosis, prognosis, genetic and epigenetic alterations, tumor microenvironment, stemness, immune infiltration cells, function enrichment, single-cell analysis, and drug response across cancers were conducted based on multiple computational… More > Graphic Abstract

Abstract Fused deposition modeling (FDM) with foaming materials offers the capability to generate internal porous structures through in-situ foaming, imparting favorable characteristics such as weight reduction, shock absorption, thermal insulation, and sound insulation to printed objects. However, the process planning for this technology presents challenges due to the difficulty in accurately controlling the foaming rate, stemming from a complex underlying mechanism that remains poorly understood. This study introduces a multi-sensor platform for FDM with foaming materials, facilitating in-situ process monitoring of temperature field information during material modeling and quality evaluation of printed objects, i.e., abnormal foaming… More >

Abstract Tannin foam is a new functional material. It can be widely applied to the automobile industry, construction industry, and packaging industry due to its wide range of raw materials, renewable, easily degraded, low cost and almost no pollution. Preparing tannin foam is a very complex process that includes high temperature, two phases, mechanical agitation, and phase change. To investigate the influence of the stirring velocity and paddle shape, simulation was calculated by making use of the volume of fluid (VOF) method and multiple reference frame (MRF) method in a three-dimensional flow field of tannin-based foaming… More > Graphic Abstract
