Mg(SPh)2 as a Catalyst for Efficient Photocatalytic Alkylation Reactions of Active Methylene Compounds with Nonactivated Alkenes

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Mg(SPh)2 has been found to be a highly active catalyst in photocatalytic alkylation reactions of active methylene compounds with nonactivated alkenes. The desired reactions proceeded smoothly to afford the corresponding alkylated products in high yields with low catalyst loadings (0.2–0.3 mol%). This protocol is applicable to a continuous‐flow

Dual Photoredox/Cu‐Catalysis Enables Diastereoselective Synthesis of 3‐β‐Ethynyltropanes via Decarboxylative Alkynylation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A copper‐catalyzed decarboxylative alkynylation of tropanes is developed. This approach works under mild conditions and selectively produces a range of 3‐β‐alkynylated tropanes. Moreover, it provides a versatile and convergent platform for further functionalization of the triple bond.

Synergistic Visible Light Nanophotocatalysis and Asymmetric Organocatalysis for the Stereoselective α‐Alkylation of Aldehydes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
An unprecedent dual catalytic nanophotocatalytic and asymmetric organocatalytic system for the α‐functionalization of aldehydes is developed using carbon nanodots as photosensitizers. The optimized methodology yields the alkylated products with up to 94% yield and up to 98:2 e.r., evidencing the possible recycling of the nanocatalysts.

Carbon‐Cloth Supported ZnO Nanorods as Binder‐Free Zinc‐Ion Battery Anodes: An Investigation into the Electrode Formation Process

open access: yesAdvanced Sustainable Systems, EarlyView.
A freestanding ZnO nanorod array on carbon cloth (ZnO/CC) is synthesized via hydrothermal growth and studied during its electrochemical reduction to Zn. Advanced characterization techniques (SEM, HRTEM, and STXM) reveal the morphochemical evolution of ZnO nanorods, providing unprecedented insights into the ZnO‐to‐Zn conversion mechanism.

Bifunctional WO3 Photoelectrodes Decorated by Inkjet Printing for Solar Supercapacitors

open access: yesAdvanced Sustainable Systems, EarlyView.
WO3 bifunctional photoelectrodes, produced by screen printing and then superficially decorated by inkjet printing, are successfully applied to prepare solar supercapacitors. Under illumination, the areal capacitance is enhanced thanks to the positive contribution of the photogenerated charges and the higher exposed area; its value becomes even more ...

Emerging Therapeutic Strategies for Hearing Loss

open access: yesAdvanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design
