A Boric Acid‐SnO2 Composite for Interfacial Stabilization of Highly Efficient Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The interaction between BA and FAI can inhibit the oxidation of iodide ions to elemental iodine (I2) in perovskite films, significantly improving the films' UV stability, and the power conversion efficiency (PCE) of the device containing BA reaches 25.7%.

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Preparation and Structure of Meta‐Hydroxy‐Substituted Aryliodonium Salts: New Structural Type of Phenol‐Derived Hypervalent Iodine Compounds

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The previously unknown meta‐hydroxy‐substituted aryliodonium salts were prepared by a two‐step one‐pot synthesis from 3‐acetoxy‐1‐[(diacetoxy)iodo]arenes and arylboronic acids. This procedure works well with halogen‐, methyl‐, methoxycarbonyl‐, or methoxy‐substituted arylboronic acids as well as naphthalenylboronic acids, phenanthren‐9‐ylboronic acid ...

Carbonylative Suzuki–Miyaura Coupling of 1‐Iodoglycals Mediated by the N‐Heterocyclic Carbene Catalyst PEPPSI: Preparation of C‐Acyl Glycosides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...

Multifunctional ionic liquid boosts the efficiency of hole transport layer‐free carbon‐based perovskite solar cells beyond 20%

open access: yesFlexMat, EarlyView.
HTL‐free carbon‐based PSCs are promising in stability but limited by efficiency. Systematic screening identifies DMAFo as an optimized ionic‐liquid additive: the DMA+ regulates lattice distortion and relieves residual stress, while Fo‒ passivates halide vacancies, and ameliorates band‐alignment.
