Thermosetting resin compositions based on novolac and modified novolac
Advances in Polymer Technology, 2011 AbstractNovel formaldehyde novolac resins at various molar ratios of monomers (4,4′‐methylenedianiline/p‐nonylphenol/p‐formaldehyde) were synthesized in the presence of an acid catalyst. The obtained resins were characterized by using elemental analysis, FT IR, and 1H NMR spectroscopic methods.

Carbon Neutralization, Volume 5, Issue 3, May 2026.Schematic diagram of challenges and advanced strategies by CBP after thickness reduction. ABSTRACT The proton exchange membrane fuel cell (PEMFC) converts clean hydrogen's chemical energy into electricity and is vital for carbon neutrality. However, its development is limited by low volumetric power density and high cost.

Studies on Allyl Ether of Novolac
Kobunshi Kagaku, 1965 アリルエーテル化ノボラックの硬化反応および硬化物の性質を比較検討することにより次のような知見を得た。1) アリルエーテル化ノボラックは通常のビニルモノマーで橋かけすることにより, 不溶不融の硬化物を与え, 硬化物の性質は用いたモノマーや開始剤の種類に関係がある。2) 多くのモノマーに対してカチオン系開始剤による硬化はすみやかに完全に進むのに対し, ラジカル系開始剤では不完全に進むか, または全然進行しないものが多い。3) 開始剤を添加した直後の樹脂および硬化生成物にESRの吸収が認められた。これはその中にかなりの量の不対電子が安定に存在していることを示している。このことより硬化反応にはカチオンおよびラジカルのいずれもが寄与していると推定される。4 ...

Advanced Materials, Volume 38, Issue 21, 13 April 2026.We present a microfabrication and integration strategy for lead halide perovskite photodetectors on electronic readouts. Standard photolithography, aqueous processing, selective transparent electrode etching, and plasma‐assisted pixel isolation enable precise monolithic integration of patterned 400 × 400 perovskite microphotodetector arrays on a CMOS ...
