Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

open access: yesAdvanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

open access: yesAdvanced Healthcare Materials, EarlyView.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...

Evaluation on the Use of Synthetic Essential Oils as Perfumery Diluent in Yenagoa, Bayelsa State, Nigeria

open access: yesJournal of Applied Sciences and Environmental Management
Essential Oils (EOs) is responsible for their essence or odor, however, the natural composition of the product has been long defeated with the introduction of synthetic products to gag the inequality in demand and supply chain.

Synergistic Effect of Zataria multiflora Boiss. and Bunium persicum (Boiss.) B. Fedtsch. Essential Oils on Linseed Oil Oxidative Stability [PDF]

open access: yesJournal of Medicinal Plants and By-products, 2014
We studied the antioxidant activities of the essential oils of Zataria multiflora Boiss. (ZEO) and Bunium persicum (Boiss.) B. Fedtsch (BEO) in mixed form on linseed oil using (DPPH•), ­(­ABTS•+), H2O2 scavenging, and reducing power assays.

Fructose‐Based Single‐Chain Polymer Nanoparticles for GLUT1–Mediated Delivery: Impact of Polymer Design on Uptake and In Vivo Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Single‐chain nanoparticles have been proposed as drug delivery carriers, but adding a tail can significantly enhance their performance. This was demonstrated using a tadpole‐like structure comprising a head prepared from a UV‐crosslinked fructose‐based glycopolymer capable of targeting GLUT receptors, combined with a PEG‐based tail. Compared with other

Essential oil composition of Bacopa imbricata (Benth.) pennel collected at wet and dry Amazonian seasons

open access: yes, 2015
The volatiles of Bacopa imbricata, collected at wet and dry Amazonian seasons were obtained by hydrodistillation and analyzed by GUM and GUMS. Comparison with the essential oil obtained from the samples collected from the same locality shows noticeable ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
