Effects of femtosecond laser texturing on the corrosion and stress corrosion cracking resistances of the 316L austenitic stainless steel additively manufactured by binder jet printing
No full textThe impact of femtosecond laser texturing (FLT) on the corrosion and stress corrosion cracking (SCC) behavior of binder jet printed (BJP) 316L stainless steel, both in its as-printed form and after hot isostatic pressing (HIP), is investigated. Hierarchical micro- and nano-surface architectures were produced using FLT through 200, 400, and 800 laser passes, corresponding to low-, medium-, and high-depth textures, respectively. The latter two resulted in superhydrophobic surfaces, while the low-depth texture imparted superhydrophobicity to BJP 316L but only hydrophobicity to BJP+HIP 316L. Compared to the low-depth textures, the medium- and high-depth textures significantly reduced the adhesion of corrosive media. Cyclic potentiodynamic polarization tests showed that FLT enhanced localized corrosion resistance in BJP 316L but diminished it in BJP+HIP 316L. Corrosion rates correlated directly with increasing surface roughness, following the order 200 < 400 < 800 passes. Crucially, medium-depth FLT markedly improved SCC resistance in BJP 316L. Post-FLT, the SCC performance of BJP 316L matched that of their HIP-treated counterparts. These findings demonstrate that FLT is a promising post-processing strategy to bolster both localized corrosion and SCC resistance in additively manufactured 316L stainless steel.Version of Record 14 October 2025journal articl
Unemployment, Fiscal Competition, and the Composition of Public Expenditure
Full text linkThis paper investigates the efficiency of equilibrium policies and public expenditure composition under labor market imperfection in a fiscal competition model. The sources of the inefficiency in supplying public goods and inputs with a capital tax are the employment stimulus and fund-raising effects of public inputs and fiscal and employment externalities. Public goods and public inputs are provided optimally if public expenditures are financed by capital and lump-sum taxes. However, if the capital tax is solely available, then public goods and public inputs can be either undersupplied or oversupplied in the second-best sense because jurisdictional governments seek to attract capital and create employment and tax revenues. Hence, in contrast to reports of the earlier literature on fiscal competition, an increase in public input expenditure financed by a decrease in public goods expenditure improves social welfare, depending on the inefficiencies of public goods and public input supplies.First published online June 13, 2025journal articl
New classifications of B-cell neoplasms: a comparison of 5th WHO and International Consensus classifications
Full text linkIn 2024, the World Health Organization (WHO) launched a new classification of lymphoid neoplasms, a revision of the previously used Revised 4th Edition of their classification (WHO-4R). However, this means that two classifications are now in simultaneous use: the 5th Edition of the WHO classification (WHO-5) and the International Consensus Classification (ICC). Instead of a comprehensive review of each disease entity, as already described elsewhere, this review focuses on revisions made in both the WHO-5 and ICC from WHO-4R and discrepancies between them regarding B-cell neoplasms. Similarities include cutaneous marginal zone lymphoma, cold agglutinin disease, non-primary effusion lymphoma-type effusion-based lymphoma, and gray zone lymphoma. Differences include plasma cell neoplasms, high-grade B-cell lymphoma (double hit lymphoma), follicular lymphoma, LPD with immune deficiency and dysregulation, extranodal large B-cell lymphoma, transformations of indolent B-cell lymphomas, and diffuse large B-cell lymphoma, not otherwise specified. Understanding the similarities and differences between the two latest classifications will aid daily diagnostic practice and future research on lymphoid neoplasms.Online Published: 28 May 2024journal articl
