SPIRO-COMPOUNDS. PART V. THE FORMATION AND TRANSFORMATION OF SPIRO-COMPOUNDS FROM 3-AND 2-METHYLCYCLOHEXANONES.

open access: yes, 1938
Spiro-compounds have been built up from methylcyclohexanone to examine, on the basis of the valency deflexion hypothesis, the nature of strain in cyclohexane ring in which ortho or meta positions are occupied by groups. β-Methylnaphthalene has been obtained as a product of dehydrogenation of 3-methylcyclohexane-spiro-cyclopmtane-­5'-carboxylic acid.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

open access: yesAdvanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Interfacial Engineering by Metallic Ions and Organic Ammonium Ligand Passivation for Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
A synergistic approach using phenethylammonium iodide (PEAI) and antimony iodide (SbI3) enhances the operational stabilities of perovskite solar cells by providing p‐type doping effect, suitable band energy alignment, reduced defect density, and minimized surface ion vacancies in the perovskite films.

Silver(I) triflate-catalyzed protocol for the post-ugi synthesis of spiroindolines

open access: yes, 2019
A silver(I) triflate-catalyzed protocol for the post-Ugi synthesis of tetracyclic spiroindolines has been developed. The protocol worked best for indole-3-carbaldehyde-derived Ugi adducts obtained using anilines and 3-aryl propiolic acids.

Fungal Origins of the Bicyclo[2.2.2]diazaoctane Ring System of Prenylated Indole Alkaloids [PDF]

open access: yes, 2012
Over eight different families of natural products, consisting of nearly seventy secondary metabolites, which contain the bicyclo[2.2.2]diazaoctane ring system, have been isolated from various Aspergillus, Penicillium, and Malbranchea species. Since 1968,

Scalable Manufacturing of Roll‐to‐Roll Slot‐Die Coated Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Roll‐to‐roll (R2R) slot‐die coating is emerging as a scalable pathway for perovskite solar cells. This mini‐review summarizes advances in ink design, drying control, and electrode integration that enable high‐efficiency flexible devices and modules. Challenges in throughput, stability, and sustainable processing are outlined, guiding the translation of

Robust and Tailored 1D/3D Heterojunction for Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
This study successfully established a robust 1D/3D heterojunction, characterized by a stable 1D phase, favorable lattice matching, strong interface binding, and effective defect passivation. The resulting epitaxial perovskite film demonstrates preferential vertical orientation of (100) facets, thereby facilitating carriers’ transport and stress relief.
