Early Acitretin Therapy in a Patient With Harlequin Ichthyosis

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Harlequin ichthyosis (HI) is a rare, severe congenital disorder of keratinization caused by pathogenic variants in the ABCA12 gene resulting in thick, hyperkeratotic plates, deep fissures, and characteristic facial and limb abnormalities.

Cobalt‐Doped Diamond‐Like Carbon Coatings Combined With Functionalised Polymers for Enhanced Tribological Performance

open access: yesLubrication Science, EarlyView.
ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.

Health Hazard Manual For Cutting Oils, Coolants, and Metalworking Fluids [PDF]

open access: yes, 1991
[Excerpt] The metalworker can be exposed to cutting oils during application by two basic routes of entry: skin contact and inhalation. The higher risk jobs tend to be those with high cutting speeds, heavy oil flow, and continuous contact, which may ...

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

open access: yesLubrication Science, EarlyView.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Resin additive improves performance of high-temperature hydrocarbon lubricants [PDF]

open access: yes, 1971
Paraffinic resins, in high temperature applications, improve strength of thin lubricant film in Hertzian contacts even though they do not increase bulk oil viscosity.

Electrochemical Monitoring of Steel Corrosion in NS4 Solution Under Cathodic Protection Environment: Insights of Electrochemical Impedance Spectroscopy

open access: yesMaterials and Corrosion, EarlyView.
Electrochemical impedance spectroscopy (EIS) monitored corrosion on mild steel under cathodic protection in soil‐like conditions. CP reduced corrosion from 410 to 7 µm/yr, shifting the mechanism from mixed activation–diffusion to activation‐controlled, enabling protective calcareous and oxide film formation.
