3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Ecologically benign lubricants - Goodbye mineral oil

open access: yes, 2022
1 S.It is of great interest to replace mineral oil in coolants by renewable resources that have a better ecological life cycle performance. Thus, the technical performance and the potential environmental impacts of ester oils made of animal fat and used ...

Sensitivity of TEHL simulations to the use of different models for the constitutive behaviour of lubricants

open access: yes, 2023
This study compares the film thickness, lubricant temperature, and traction curves of two groups of commonly used constitutive models for lubricants in thermo-elastohydrodynamic lubrication (TEHL) modelling.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

open access: yesAdvanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

ECOLOGICAL AND ECONOMICAL ASPECTS OF USE OF BIO-LUBRICANTS AND CONVENTIONAL LUBRICANTS [PDF]

open access: yes, 2016
It is believed that more than 50 % of produced lubricants during or/and after the operation is due directly or indirectly to the environment. For these reasons, in areas where the application of lubricant is related to the total "loss" in the environment,

Oxidative and extractive desulfurization of petroleum middle distillates, using imidazole ionic liquids

open access: yesFuel Communications, 2021
The desulfurization of four petroleum distillates i.e. kerosene, light gas oil (LGO), heavy gas oil (HGO) and light cycle oil (LCO), with sulfur content 0.206–1.272% w/w, was carried out using the hydrogen peroxide-acetic acid oxidative system, in ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.
