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 ...

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

open access: yesAdvanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Solvent-mediated extraction of fatty acids in bilayer oil paint models: a comparative analysis of solvent application methods

open access: yesHeritage Science, 2019
The impact of solvent exposure on oil paintings and the differences between solvent application methods are longstanding topics in cleaning studies. Solvent exposure is ideally kept to a minimum, because solvent swelling can lead to the extraction and ...

Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents

open access: yesAdvanced Healthcare Materials, EarlyView.
Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Degradation Products Assessment of the Wooden Painted Surfaces from a XVIIth Heritage Monastery

open access: yesApplied Sciences, 2023
Currently, approximately 70% of paintings in museum collections are affected by the presence of metallic soaps, evidenced by spherical globules visible on the surface of the paintings.

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Infrared chemical mapping of degradation products in cross-sections from paintings and painted objects

open access: yesHeritage Science, 2019
Paintings and painted objects are quite susceptible to degradation, as paint layers are usually composed of complex mixtures of materials that can participate in chemical degradation processes.

DIPOLE MOMENTS OF METALLIC SOAPS

open access: yes, 1950
The dipole moments of six metallic soaps, viz., the oleates of Zn Cu, Mg, Ni, Pb and Ca have been determined by a heterodyne beat method. The values Are 0.29 D, 1.20 D, 1.66 D, 2.67 D, 4.29 D and 4.49 D respectively. Though the metallic soaps are generally regarded as non-polar from their physico-chemical, particu­larly solubility behaviour, being ...
