Wear Tests of a Potential Biolubricant for Orthopedic Biopolymers [PDF]

Lubricants, 2015
Most wear testing of orthopedic implant materials is undertaken with dilute bovine serum used as the lubricant. However, dilute bovine serum is different to the synovial fluid in which natural and artificial joints must operate. As part of a search for a lubricant which more closely resembles synovial fluid, a lubricant based on a mixture of sodium ...

Synthesis, reactivity and application studies for different biolubricants [PDF]

Chemistry Central Journal, 2014
Les huiles végétales ont des propriétés uniques différentes en raison de leur structure chimique unique. Les huiles végétales ont une plus grande capacité à lubrifier et ont des indices de viscosité plus élevés. Par conséquent, ils sont examinés de plus près en tant qu'huile de base pour les biolubrifiants et les fluides fonctionnels.

Market potential of biobased chemicals: a qualitative network analysis of adoption dynamics in South Africa’s bioeconomy

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 854-878, March/April 2026.
Abstract The premise of a bioeconomy is the replacement of nonrenewable and unsustainable fossil‐derived resources and associated technologies with more sustainable alternatives. The adoption of biobased chemicals contributes toward the growth of a bioeconomy and is dependent on market and industry requirements.

LipoGels: Robust Self‐Lubricating Physically Cross‐Linked Alginate Hydrogels Embedded with Liposomes

Advanced Functional Materials, Volume 36, Issue 7, 22 January 2026.
Physically cross‐linked alginate hydrogels embedded with 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine liposomes (LipoGels) are prepared under optimized conditions to avoid shrinkage and achieve structural uniformity. LipoGels demonstrate robust mechanical strength (Young's modulus ≈1 MPa), excellent lubrication (friction coefficient ≈0.021), and ...
