Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
Perovskite solar cells (PSCs) are well positioned for a successful market uptake. This is due to an unprecedented improvement of their efficiency and stability since the first report in 2009. In this review paper, the building blocks for the scalable manufacturing and future commercialization of flexible PSCs and their pathway to impact will be ...

Multiphoton Multicomponent Reactions: Discovery of the 2‐Photon Ketene 4‐Component Reaction (2P‐K‐4CR)

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Multicomponent reactions triggered by multiple photons: complex heterocycles can be synthesized in a regio‐ and stereoselective manner via a double photoactivation using visible light from simple building blocks, exploiting the combination of ketene 3‐component reaction and Paternò–Büchi cycloaddition.

Visible Light‐Promoted Esterification of Carboxylic Acids via Photoacid Generation Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A novel, environmentally friendly photochemical method for the esterification of carboxylic acids with alcohols using arylazo sulfones as photoacid generators was developed. This approach avoids traditional acidic catalysts, purification did not require chromatography and the method proved effective under continuous flow conditions for enhanced ...

Chemical preservatives in foodstuffs. V. The effect of benzoic acid on the sporulation of Bacillus megaterium

open access: yesAgricultural and Food Science, 1962
In Bacillus megaterium, benzoic acid does not inhibit the reproduction or germination of already-formed spores when the concentration of undissociated benzoic acid is 10-5-m, but it prevents the formation of new spores in this concentration.

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

Influence of yogurt cultures on benzoic acid content in yoghurt

open access: yesCzech Journal of Food Sciences, 2000
Benzoic acid is not the natural metabolite in ruminants, therefore it is blocked in their gastrointestinal system in the form of benzoylglycine (hippuric acid).

Photo‐Rechargeable Organic Supercapacitor via Light‐Activated Electrolytes

open access: yesAdvanced Science, EarlyView.
A photo‐rechargeable organic supercapacitor device is fabricated comprising activated charcoal electrodes and 2‐nitrobenzaldehyde as the electrolyte. The operation principle of the device relies on the photoinduced transformation of 2‐nitrobenzaldehyde into electrochemically active benzoic acid derivatives.
