Analysis of Terpolymerization Systems for the Development of Carbon Fiber Precursors of PAN
International Journal of Polymer Science, Volume 2020, Issue 1, 2020., 2020 The thermal stabilization of polyacrylonitrile fibers (FPAN) is one of the most important steps in the production of carbon fibers (CFs). In this paper, new precursor polymers from PAN have been synthesized with different chemical characteristics using a solution polymerization, and FPAN was obtained using an unconventional wet spinning system in the ...

Molecularly Templated Buried Interfaces for Inverted Perovskite Solar Cells
Angewandte Chemie International Edition, EarlyView.We demonstrate a molecularly matched buried interface between SAM and perovskite, enhancing adhesion and passivating defects. This optimized interface achieves 26.58% power conversion efficiency and 86.72% fill factor with exceptional operational stability in both large‐area and wide‐bandgap devices, thereby increasing efficiency and prolonging ...

Lipids, Volume 61, Issue 4, Page 459-466, July 2026.ABSTRACT The effects of fish oil supplementation on omega‐3 (n‐3) polyunsaturated fatty acids, particularly intermediates between eicosapentaenoic acid (EPA, 20:5n‐3) and docosahexaenoic acid (DHA, 22:6n‐3), that may provide valuable metabolic information, have not been fully characterized in older populations.

IL‐4 induces cAMP and cGMP in human monocytic cells
Mediators of Inflammation, Volume 4, Issue 4, Page 298-305, 1995., 1995 Human monocytes, preincubated with IFN‐γ respond to IL‐4 by a cGMP increase through activation of an inducible NO synthase. Here, IL‐4 was found to induce an accumulation of cGMP (1 – 3 min) and cAMP (20 – 25 min) in unstimulated monocytes. This was impaired with NOS inhibitors, but also with EGTA and calcium/calmodulin inhibitors.

Global Observations of Acetyl Peroxynitrate (PAN) in the Remote Troposphere
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract We present global airborne observations of acetyl peroxynitrate (CH3C(O)OONO2, PAN) in the remote troposphere from the Atmospheric Tomography (ATom) campaign. These observations show that biomass burning is the dominant source of PAN in the Southern Hemisphere (SH).

Meridiano 47 - Journal of Global Studies, 2019 O Tratado sobre a Proibição de Armas Nucleares (TPAN) foi aberto para assinaturas em 2017, e em outubro de 2019 o tratado tinha 79 signatários. No entanto, nenhum Estado Nuclearmente Armado assinou o tratado. Este artigo argumenta que o TPAN é tanto uma inovação no regime de não proliferação de armas nucleares quanto um tratado inadequado para atingir ...
