Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments

International Journal of Cosmetic Science, EarlyView.
One important aspect of daily hair grooming routines is whether, after combing, conspicuous numbers of broken hairs are observed. Machine‐based cyclic combing of hair tresses serves as a good indicator for early hair breakage and as a suitable measure to determine the effect of an ingredient/product/process on hair ‘strength’.

Compatibility of personal care thickening polymers in sulphate‐free surfactants

International Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

Meteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

Real‐Time Kinetic Monitoring of Dental Composite Photopolymerization by Photo‐DSC

Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Real time photo‐DSC was used to investigate polymerization kinetics of Bis‐GMA/TEGDMA dental composites. The study thoroughly examines how photo‐initiator type, concentration, silica filler content, and moisture affect conversion and curing rate. Results highlight optimal initiator systems, filler effects, and moisture tolerance, providing valuable ...

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Synthesis and Evaluation of the First Generation of Glycosylated Nucleoside Analogues as Potential Inhibitors of the Base J Metabolism in Kinetoplastid Parasites

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Novel analogues of the kinetoplastid‐specific DNA base J unlock a new way to target parasite epigenetic regulation. Some compounds selectively inhibit Leishmania and Trypanosoma species without harming human cells, revealing a promising route toward innovative antiparasitic therapies.

L’isolation dans les projets de bâtiments entre le choix et l’exigence

Revue des Énergies Renouvelables, 2015
Dans notre pays, les coutumes de conception des structures sont conservées depuis des décennies avec le même rythme de politique. Nous cherchons l’économie, la construction avec le moindre coût et avec les matériaux habituellement utilisés. Malgré que le

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.
