Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

open access: yesJournal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Biodegradable Natural Polymer‐Based Drug Delivery Systems for Bone Tissue Engineering

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT The increasing incidence of bone diseases and injuries, especially among aging populations, has underscored the shortcomings of traditional treatments such as bone grafts and metal implants, which often face complications including immune rejection, mechanical failure, and delayed healing.

Rheology–Performance Framework for PA6/GO Nanocomposites via a Hybrid Processing Route

open access: yesPolymer Engineering &Science, EarlyView.
Hybrid PA6/GO nanocomposites with tuned melt rheology and improved thermal–mechanical performance. ABSTRACT Balancing melt processability with stiffness and heat resistance remains a central challenge for PA6 nanocomposites. Here, graphene oxide (GO) was synthesized by a modified Hummers method and incorporated into PA6 via a hybrid route (solution ...

Hybrid Thermosetting Polymer Nanocomposite Thin Films With Optimized Thermal Conductivity and Mechanical Reinforcement

open access: yesPolymer Engineering &Science, EarlyView.
3ω Study of Hybrid Nanostructure Epoxy Thin Films for Thermal Interfaces. ABSTRACT Epoxy‐based thin films reinforced with graphene oxide (GO), hexagonal boron nitride (h‐BN), and their hybrid combination (GO/h‐BN) at low filler contents (< 1 wt%) were developed to advance thermosetting nanocomposites for high‐performance thermal interface materials ...

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
