Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

Influence of Fe Particle Size Distribution on Chemical Homogeneity, Microstructure, and Crack Formation in Fe–SiC Powder Blends Processed by PBF‐LB/M

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of Fe particle size on in situ alloying of Fe–SiC powder blends in PBF‐LB/M is revealed. Contrary to expectations, the coarser Fe fraction provides a broader crack‐free processing window and slightly improved elemental homogeneity while producing higher but more variable hardness. The results highlight a complex trade‐off between particle

Impacts of sulfur application on microbial communities and functional attributes in rubber plantation soil

open access: yesBMC Microbiology
Elemental sulfur is widely used in fungicide applications to control crop diseases in agricultural systems, but its effects on soil microbial communities are largely unknown.

Sulfur Metabolites in the North Pacific Subtropical Gyre and Transition Zone

open access: yes, 2021
Sulfur is an essential nutrient for life and a constituent of many important biomolecules. Phytoplankton in the surface ocean use assimilatory reduction pathways to reduce inorganic sulfur, primarily in the form of sulfate (SO4 2-), into the necessary

Edible Cuttlefish Ink: Complex Chemistry, Structure, and Electrical Response

open access: yesAdvanced Engineering Materials, EarlyView.
An integrated approach of chemistry‐structure‐electrical properties is used to assess the potential of edible cuttlefish ink as a bio‐based conductive ink for printable electronics. Chromatography and Neutron Activation Analysis reveal a fascinating molecular and elemental diversity.

Volcanically driven Hg–C–S cycling and climate change across the Early Permian Artinskian warming

open access: yesCommunications Earth & Environment
Climate change and driving mechanisms of the Late Paleozoic Ice Age, an ideal analogue to the present-day global change, remain controversial. Here we propose a volcanic carbon–sulfur radiative forcing mechanism by investigating the Lower Permian ...

Deep-sea in situ and laboratory multi-omics provide insights into the sulfur assimilation of a deep-sea Chloroflexota bacterium

open access: yesmBio
Chloroflexota bacteria are abundant and globally distributed in various deep-sea ecosystems. It has been reported based on metagenomics data that two deep-sea Chloroflexota lineages (the SAR202 group and Dehalococcoidia class) have the potential to drive

Understanding the lithium–sulfur battery redox reactions via operando confocal Raman microscopy

open access: yesNature Communications, 2022
The complex redox processes in lithium–sulfur batteries are not yet fully understood at the fundamental level. Here, the authors report operando confocal Raman microscopy measurements to provide mechanistic insights into polysulfide evolution and sulfur ...

Sulfur-Doped Carbon Nanotemplates for Sodium Metal Anodes

open access: yes, 2018
Sodium metal is a good candidate as an anode for a large-scale energy storage device because of the abundance of sodium resources and its high theoretical capacity (∼1166 mA h g–1) in a low redox potential (−2.71 V versus the standard hydrogen electrode).
