Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey

Arthritis Care &Research, EarlyView.
Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...

Ti4C3 and Ti4N3 MXenes: ultrafast Na-ion diffusion and figure-of-merit benchmarking for sodium-ion battery anodes

Materials Today Sustainability
Here, density functional theory calculations are used to evaluate Ti4C3 and Ti4N3 MXenes as sodium ion-battery (SIB) anodes. Both MXenes offer multiple energetically favorable Na adsorption sites with strong binding, supporting uniform Na accommodation ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Thermoelectric properties of carbon nanotube/silicone rubber composites

Journal of Experimental Nanoscience, 2017
In this paper, we have studied the relevant physical quantities to the figure of merit of carbon nanotube (CNT)/polydimethylsiloxane composites at different loadings, and found that with increasing the CNT loadings, the electrical conductivity jumps ...

Editorial: Figures Of No Merit [PDF]

Optical Engineering, 1986
The subject of this editorial is figures-not the kinds of figures seen on the beach or those displayed in the columns of a ledger. The figures of concern here are those included with manuscripts submitted to Optical Engineering. You might ask, "Why an editorial on figures?" I'll tell you why-because we have been receiving too many crummy ones!

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Mathematical Tools that Connect Different Indexing Analyses

Proceedings, 2020
As mathematical tools that can be commonly used for indexing analyses from different types of experimental patterns, we have recently developed (i) rules on forbidden hkl’s that can be used even when the space group and setting are unknown, (ii) an ...
