A General Cyanine‐Based Platform for Designing Robust Dual‐Channel Near‐Infrared Fluorescent and Photoacoustic Probes

open access: yesAdvanced Functional Materials, EarlyView.
The study presents a general cyanine‐based platform CySN for designing robust dual‐channel near‐infrared fluorescent (NIRF) and photoacoustic (PA) probes with high ratiometric signals change. CySN enables the construction of highly sensitive and selective dual‐channel NIRF/PA probes for both small molecule and enzyme biomarkers (H2O2, esterase ...

Constructing Covalent Organic Polymers through Dative B─N Bonds: Synthesis, Single Crystal Structures, and Physical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Exchange Rate Behavior and Exchange Rate Puzzles: Why the XVIII Century Might Help [PDF]

open access: yes
This article explores the behavior of exchange rates in Spain during the XVIII century. We posit that exchange rates were the result of both government intervention over nominal values of currencies and the estimate that the market –of bills of exchange-

Active Hydrogen for Electrochemical Ammonia Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
This review provides a comprehensive overview of the active hydrogen (H*) for electrochemical ammonia synthesis with particular attention given to the regulation of H* generation and consumption to suppress the competition of hydrogen evolution reaction and enhance the yield, selectivity, and Faradaic efficiency of ammonia.
