Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Investigation of Cutting Tools and Working Conditions Effects when Cutting Ti-6al-4V using Vegetable Oil-Based Cutting Fluids

, 2015
Power consumed in metal cutting is typically converted into heat near the cutting tool edge. Cutting fluids are then provided to a cutting zone in order to improve the tribological characteristics of machining processes and to dissipate the generated ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, Volume 68, Issue 3, Page 317-329, June 2026.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 3, Page 1587-1595, May/June 2026.
Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...

Marked Impact of Regulatory Bans on Formaldehyde and Formaldehyde‐Releaser‐Induced Allergic Contact Dermatitis: A Retrospective Cohort Study (1996–2024) From Turkey

Contact Dermatitis, Volume 94, Issue 5, Page 515-523, May 2026.
The overall prevalence of sensitization to FA/FRs was 1.9% (48/2592). ACD was diagnosed in 37.5% (18/48), comprising non‐occupational ACD (83.3%) and occupational ACD (16.7%). FA 1%–2% aq. failed to detect FR sensitisation in 31.9% (n = 15/47) and FR‐induced ACD in 35.3% (n = 6/17) of patients.

Interventions and Implementation Strategies for Preventing Occupational Contact Dermatitis: A Scoping Review

Contact Dermatitis, Volume 94, Issue 5, Page 437-464, May 2026.
ABSTRACT Numerous preventive measures for occupational contact dermatitis (OCD) have been evaluated, but their effectiveness varies, suggesting that contextual factors and corresponding implementation strategies are important. This scoping review aimed to identify preventive interventions for OCD and explore their implementation strategies and outcomes.
