We show that ionic liquids (ILs) interact with electron-rich, porous polyphosphazene (PPZ), to form hybrid PPZ-IL nanoreactors able to simultaneously capture and transform CO2 into carbonates. The PPZ nanospheres swell in organic solvents and effectively a ...

The world needs to move from a fossil fuel to a renewable energy based society. With the increasing electricity production from wind and PV, short and long term energy storage are becoming one of challenge of the 21st century. While batteries are the prefe ...

This work is addressing the arenes' hydrogenation-the processes of high importance for petrochemical, chemical and pharmaceutical industries. Noble metal (Pd, Pt, Ru) nanoparticles (NPs) stabilized in hyper-cross-linked polystyrene (HPS) were shown to be a ...

Cyanine dyes represent a class of ionic functional materials used by a broad heterogeneous science community contain-ing biologists, chemists, physicists and materials scientists. Their diverse application opportunities are ranging from fluorescence marker ...

An ionic liquid encompassing a bulky tertiary amine was synthesized and used as a dual solvent-reactant for the formation of a frustrated Lewis pair with tris(pentafluorophenyl) borane, forming a pseudo-frustrated Lewis pair-ionic liquid system. The ionic ...

We demonstrate the application of inkjet-printed near room-temperature chemiresistors composed of polymer-carbon black (CB) composites for detecting and classifying volatile organic compounds (VOC). Our results demonstrate that the printed sensors can sele ...

Online characterization of aerosol composition at the near-molecular level is key to understanding chemical reaction mechanisms, kinetics, and sources under various atmospheric conditions. The recently developed extractive electrospray ionization time-of-f ...

Overprediction of fine-particle ammonium-sulfate molar ratios (R) by thermodynamic models is suggested as evidence for interactions with organic constituents that inhibit the equilibration of gas-phase ammonia with aerosol sulfate and questions the equilib ...

The present work deals with the defect chemistry and charge transport properties in halide perovskites, and in particular in the archetypal methylammonium lead iodide. These materials are extensively researched due to their very promising application as li ...

Three hole transport materials (HTMs) based on a substituted triphenylamine moiety have been synthesized and successfully employed in triple-cation mixed-halide PSCs, reaching efficiencies of 19.4 %. The efficiencies, comparable to those obtained using spi ...

Energy Storage in the chemical bonds of water, a process accessible through electrochemical conversion, is a simple approach to compensate supply fluctuation common to sustainable energy production such as wind and solar. However, the water cycle is limite ...

Perovskite solar cell (PSC) technology is the flag bearer for the future of photovoltaics allowing unlimited possibilities for its application. This technology is currently limited by issues related to its scale-up, stability and the composition of the mat ...

Molecular dynamics simulations and DFT calculations suggest that leaching of palladium species from Pd nanoparticles in ionic liquids does not involve "naked" Pd(0) atoms or neutral ArPdX species formed by oxidative addition of arylhalides. Instead, the io ...

The inferior power conversion efficiency (PCE) compared to their regular counterparts (n-i-p) and undesirable stability issues of inverted (p-i-n) perovskite solar cells (PSCs) are the foremost issues hindering their commercialization. Here, for the first ...

Dye-sensitized solar cells (DSSCs) based on Cu-II/I bipyridyl or phenanthroline complexes as redox shuttles have achieved very high open-circuit voltages (V-OC, more than 1 V). However, their short-circuit photocurrent density (J(SC)) has remained modest. ...

Measuring the concentration of different compounds in aquatic ecosystem and understanding their impact on the environment are some of the main objectives in the environmental monitoring field. Trace metals, nutrients, volatile organic compounds (VOCs), bio ...

Distributed photovoltaic (PV) generation is typically connected to power distribution grids, which are not designed to host a large amount of production if it is significantly larger than their nominal electricity demand. Given the prominent role of PV in ...

Platinum nanoparticles (NPs) were synthesized in situ in the ionic liquid (IL) [Emim]NTf2 (1-ethyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide) as well as in mixtures of [Emim]NTf2 with a second IL, Lewis acid or Brønsted acid, but in the absenc ...

the most studied perovskite‑based solar cells reported up to date contain the toxic lead in its composition. photovoltaic research and development towards non‑toxic, lead‑free perovskite solar cells are critical to finding alternatives to reduce human heal ...

The authors report the fabrication and characterization of chemiresistive sensors, composed of a thermoplastic elastomer (TPE), styrene‐ethylene‐ran‐butylene‐styrene, and a high‐structure carbon black (CB) targeted for detecting hydrocarbons at or near roo ...
