Understanding the Aqueous Self‐Assembly of Raw Sophorolipid Mixtures Using a Statistical Approach Applied to Synchrotron Small Angle X‐Ray Scattering (SAXS): A Focus on pH, Dilution, Aging, and the Underestimated Role of Residual Fatty Acids

Journal of the American Oil Chemists' Society, Volume 103, Issue 10, Page 1279-1296, October 2026.
The statistical analysis of SAXS modelling data allows to identify the critical physicochemical parameters that have an impact on the phase behavior of crude sophorolipid batches. ABSTRACT The aqueous self‐assembly of raw sophorolipid mixtures has been studied by small angle x‐ray scattering (SAXS) to understand the impact of the composition ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, Volume 7, Issue 5, October 2026.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Network pharmacology and molecular simulations reveal multi-target neuroprotective potential of Rhamnolipid and Surfactin against Alzheimer’s disease

Brain Research Bulletin
Background: Alzheimer’s disease (AD), the primary cause of dementia and lacks potent therapeutic interventions. Natural biosurfactants containing Surfactin and Rhamnolipid, with neuroprotective capability and anti-inflammatory, extend favorable multi ...

Improved remediation of co-contaminated soils by heavy metals and PAHs with biosurfactant-enhanced soil washing

Scientific Reports, 2022
Due to the huge toxicity of co-contaminated soil with PAHs and heavy metals and the complexity of their remediation, it is thus critical to take effective remediation actions to remove heavy metals and PAHs simultaneously from the co-contaminated soil ...

Relay Architectures and Ecological Strategies of Quorum Sensing Effects on Microbial Interactions

Environmental Microbiology, Volume 28, Issue 10, October 2026.
Quorum‐sensing activity in one population affects neighbouring populations through direct signal perception, QS‐regulated chemical effectors, or host‐ or environment‐mediated relays. Across distinct habitats, these relay architectures are associated with ecological strategies ranging from shared signal accessibility and reciprocal responsiveness to ...
