This paper presents a new product, glass epoxy laminate reinforced aluminum (glare) -based thin-walled structures with stiffeners in the form of longitudinal ribs. The ribs rigid outer metal layer of the glare-based panels made with extra sheet forming techniques and alclad 2024-T3 alloy aluminum sheet used as adherends. The strength properties of adhesive joints between the layers of metal fiber laminates (FMLs) specified in the test three-point bending test of uniaxial tensile, drum skin tests, tensile / shear test and short-beam. Two variants of FMLs considered, with and without adhesive films adhesive films between adherends and prepreg epoxy / glass. The FMLs tested at three different temperatures associated with successfully found those under real flight operating conditions, ie -60 ° C, room temperature and 80 ° C.
It was found that the temperature does not affect the tensile strength and shear strength of FMLs tested. However, there is a noticeable increase in the stiffness of samples runs at reduced temperatures. Additional adhesive film layer between the adherends and glass / epoxy prepreg significantly improves static power strip joints in both the reduced and at high temperatures. A clear increase in critical power where buckling occurs has been clearly demonstrated in uniaxial compression test panel glare-based rigid ribs. In the case of rib-rigid panel glare-based, critical power of the average 15 370 N, while for non-remitting variant, was 11,430 N, which translates into a 34.5% increase in critical power.
Information from the relaxation behavior of the polymer film is very important to assess the durability of emulsion polymer isocyanate (EPI) as a structural adhesive for bonding wood-based products. A sequence of tensile creep test and evaluation of EPI-free volume cured adhesive film for isothermal conditions is done by dynamic mechanical analysis and positron annihilation lifetime spectroscopy, respectively.
It was the first time to explore the creep response and physical aging EPI films, as well as the related microstructural evolution. The results showed that the creep characteristics of the glass EPI intimate layer depends on the crosslinker and time elapsed, and the ideal host momentary creep curve can be constructed in terms of the modified horizontal shift method.
Strength Analysis of a Rib-Stiffened GLARE-Based Thin-Walled Structure
Brush Polymer Coating and Adhesion Technology in Skala
Creating strong joints between different materials for high performance hybrid products puts high demands on modern adhesive. Traditionally, the adhesion depends on the compatibility between the surface, often requiring the use of primer and bonding layer thickness to achieve a stable joint. Polymer brush layers allows kompatibilisasi material surface through more precise control of surface chemistry, facilitate strong adhesion through a nanometer-thin layer.
Here, we give a detailed account of our research on the adhesion promoted by the polymer brush along with examples of industrial applications. We discuss two fundamentally different adhesive mechanisms of brush polymers, namely (1) the physical bonding through entanglement and (2) chemical bonding.
Description: Caspase-1 Antibody: Caspases are a family of cysteine proteases that can be divided into the apoptotic and inflammatory caspase subfamilies. Unlike the apoptotic caspases, members of the inflammatory subfamily are generally not involved in cell death but are associated with the immune response to microbial pathogens. Members of this subfamily include caspase-1, -4, -5, and -12 and can activate proinflammatory cytokines such as IL-1β and IL-18. Caspase-1 was initially identified as an IL-1β-converting enzyme; later experiments revealed it to be a mammalian homolog of the C. elegans cell death gene ced-3 whose overexpression can induce apoptosis in fibroblasts.

Description: Caspase-1 is a cysteine protease that regulates inflammatory processes through its capacity to process and activate the interleukin-1-beta, interleukin 18, and interleukin 33 precursor proteins. The Caspase-1 gene consists of 10 exons spanning at least 10.6 kb and is mapped to 11q23, a site frequently involved in rearrangement in human cancers, including a number of leukemias and lymphomas.

It belongs to a family of cysteine proteases known as caspases that always cleave proteins following an aspartic acid residue. The Caspase-1 gene consists of 10 exons spanning at least 10.6 kb and is mapped to 11q23, a site frequently involved in rearrangement in human cancers, including a number of leukemias and lymphomas, by Southern DNA blot analysis of rodent-human hybrids and by in situ hybridization to normal human metaphase chromosomes. Caspase 1 has been shown to induce cell necrosis or pyroptosis and may function in various developmental stages.
Description: Caspase-1, an apoptosis-related cysteine protease, is a cysteine protease that regulates inflammatory processes through its capacity to process and activate the interleukin-1-beta, IL-18, and IL-33 precursor proteins. It was purified from the cytosol of the THP monocytic cell line and found that the active protease was made up of two peptides, which they called p20 and p10 based on their apparent molecular masses by SDS-PAGE. It belongs to a family of cysteine proteases known as caspases that always cleave proteins following an aspartic acid residue. The CASP1 gene is mapped to 11q23, a site frequently involved in rearrangement in human cancers, including a number of leukemias and lymphomas, by Southern DNA blot analysis of rodent-human hybrids and by in situ hybridization to normal metaphase chromosomes.

The former mechanism is demonstrated by, for example, a strong bond between the poly (methyl methacrylate) (PMMA) coated stainless steel brush and bulk PMMA, while the latter is indicated by, for example, improved adhesion between the silicon and titanium substrates, enabled by hydrosilane- modified poly (hydroxyethyl methacrylate ) (PHEMA) brushes.
