Influence of the microstructure on the degree of sensitization of a duplex stainless steel UNS S31803 aged at 650ºC [PDF]

Materials Research, 2013
This work evaluates the phase transformations during aging of an UNS S31803 DSS at 650ºC and its influence on the DOS. The material was solution treated at 1175ºC and then aged at 650ºC for times up to 360 h. SEM-BSC images indicate the formation of Cr2N,

Co‐Ligand‐Induced Electronic Modulation Controls Substrate Adsorption and Selectivity in Biomass Electrooxidation

Advanced Science, EarlyView.
A molecular design strategy is reported that introduces distinct anionic co‐ligands into Cu‐based catalysts to modulate the electronic density of the metal center and, consequently, its interaction with both OHads and HMF. The work establishes co‐ligand engineering as an effective strategy for precise interfacial adsorption control in electrocatalysis,

Selenocyanate Driven Organic Cations Homogenization in Wide‐Bandgap Perovskite

Advanced Energy Materials, EarlyView.
Selenocyanate pseudohalide doping stabilizes 1.66 eV wide‐bandgap formamidinium (FA)‐based perovskite lattices via strong FA+ hydrogen bonding and matched ionic radii. Uniform cation distribution and suppressed ion migration reduces defect losses, delivering >24% single‐junction efficiency and 32.66% perovskite/silicon tandem performance with ...

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

Materials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...
