CH\u2082F\u2082 flames have lower temperatures and suppressed H and OH radical formation, due to dominant HF-producing pathways inhibiting radical chain reactions. Despite susceptibility to blowoff, CH\u2082F\u2082 maintains high adiabatic flame temperature, allowing combustion at low oxygen if sufficient residence time is provided.  <\/p>\n        <p>[<a href=\"https:\/\/pr.eng.hokudai.ac.jp\/rc\/en\/featured\/202604fa002\/\">Featured Research<\/a>]<\/p>\n      <\/div>\n      <div class=\"content_data wp-block-group is-style-group-contentinfo\">\n    <p class=\"content_person\"><p><a href=\"https:\/\/scholar.google.com\/citations?user=3UOupVsAAAAJ&amp;hl=ja\" target=\"_blank\" rel=\"noopener\">Yusuke Konno<\/a>, Ayuto Ota, <a href=\"https:\/\/scholar.google.com\/citations?user=ZeAH_08AAAAJ&amp;hl=ja\" target=\"_blank\" rel=\"noopener\">Nozomu Hashimoto<\/a>, and <a href=\"https:\/\/scholar.google.com\/citations?user=PYx5i2UAAAAJ&amp;hl=ja\" target=\"_blank\" rel=\"noopener\">Osamu Fujita<\/a><\/p>\n<\/p>\n\n    <p class=\"content_info\"><p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0010218025006510?via%3Dihub\" target=\"_blank\" rel=\"noopener\">Combustion and Flame 284, 114614<\/a><\/p>\n<\/p>\n<\/div>\n<!-- \/\/ BLOCK: CONTENT-DATA -->\n    <\/div>\n  <\/li>\n<!-- TEMP: FEATURED_POST ARCHIVE -->\n  <li id=\"featured000468\" class=\"wp-block-post post-468 featured_post type-featured_post status-publish has-post-thumbnail hentry tag-ai tag-concrete-engineering tag-non-destructive-inspection content_type-articles content_issue-vol0002-2026 content_field-civil-engineering content_year-347\">\n    <div class=\"wp-block-group post_block is-layout-flow wp-block-group-is-layout-flow\">\n\n      <h3 class=\"wp-block-post-title\"><a href=\"https:\/\/pr.eng.hokudai.ac.jp\/rc\/en\/featured\/202604fa001\/\">Impact-echo for different level cracks detection in concrete with artificial intelligence based on un\/supervised deep learning<\/a><\/h3>\n      <div class=\"wp-block-post-content\">\n        <p>Aging concrete infrastructure such as bridges and tunnels requires effective inspection to ensure safety and durability, particularly for detecting invisible internal cracks subjected to structural integrity. Impact-echo, which is one of non-destructive testing methods, is widely used but costly and time-consuming with relying on skilled and experienced analysis. This study integrates AI with impact-echo data to improve crack detection. Supervised deep learning using FFT-transformed signals enables accurate classification of multiple crack levels, including intact condition of concrete. However, data labeling for each existing structures is impractical, so an unsupervised approach using an auto-encoder is proposed to identify internal crack levels through anomaly-based indices without labeled data.<\/p>\n        <p>[<a href=\"https:\/\/pr.eng.hokudai.ac.jp\/rc\/en\/featured\/202604fa001\/\">Featured Research<\/a>]<\/p>\n      <\/div>\n      <div class=\"content_data wp-block-group is-style-group-contentinfo\">\n    <p class=\"content_person\"><p>Jeero Pandum, <a href=\"https:\/\/researchmap.jp\/ktfmhsmt?lang=en\" target=\"_blank\" rel=\"noopener\">Katsufumi Hashimoto<\/a>, Takafumi Sugiyama, Wanchai Yodsudjai<\/p>\n<\/p>\n\n    <p class=\"content_info\"><p><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0950061825022317\" target=\"_blank\" rel=\"noopener\">Construction and Building Materials 487 142080<\/a><\/p>\n<\/p>\n<\/div>\n<!-- \/\/ BLOCK: CONTENT-DATA -->\n    <\/div>\n  <\/li>\n<!-- TEMP: FEATURED_POST ARCHIVE -->\n  <li id=\"a202510sa001\" class=\"wp-block-post post-123 content_post type-content_post status-publish hentry tag-al tag-cfrp tag-electroplating tag-ionic-liquid content_type-articles content_issue-vol0001-2025 content_field-313 content_year-347\">\n    <div class=\"wp-block-group post_block is-layout-flow wp-block-group-is-layout-flow\">\n      <h3 class=\"wp-block-post-title\">Carbon Fiber-reinforced Plastic Surface Modification by Al Electroplating in AlCl\u2083\u2013EmImCl Ionic Liquids<\/h3>\n      <div class=\"wp-block-post-content\">\n        \n<p>To improve the wear resistance of the CFRP surface, Al electroplating was formed on the surface in an ionic liquid and anodizing was also performed.
