In‐Situ Solution Complexation for n‐Type Surface‐Energetics Reconstruction in 2.0 eV Ultra‐Wide‐Bandgap Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

Volatile organic compounds emitted from fungal-rotting beech (Fagus sylvatica) [PDF]

, 2008
Chemo-communication is an important mode of interaction within ecosystem. The living organism in the ecosystem can deliver signals to conspecifics, to co-organisms, and unintentionally to their enemies, by emitting the volatile organic compounds (VOCs ...

Modeling-based determination of physiological parameters of systemic VOCs by breath gas analysis, part 2

, 2018
In a recent paper we presented a simple two compartment model which describes the influence of inhaled concentrations on exhaled breath concentrations for volatile organic compounds (VOCs) with small Henry constants.

Fragranced Products and VOCs

Environmental Health Perspectives, 2011
In the article “Scented Products Emit a Bouquet of VOCs,” Potera (2011) gave a broad overview of the work of Steinemann et al. (2010) regarding the quantification of volatile organic compounds (VOCs) from fragranced products. Unfortunately, crucial facts were omitted about the materials cited and the use of alternative substances.

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

Advanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

Research progress on the poisoning mechanism of flue gas VOCs purification catalysts

能源环境保护
In the industrial environment, the composition of flue gas is complex, and impurities in flue gas can lead to catalyst poisoning and deactivation, which severely restricts their application in practice.

Tailpipe VOC Emissions from Late Model Gasoline Passenger Vehicles in the Japanese Market

Atmosphere, 2019
High concentrations of tropospheric ozone remain a concern, and strategies to reduce the precursors of ozone, volatile organic compounds (VOCs) and nitrogen oxides, have been established in many countries.

Quartz Crystal Microbalance Based Sensor Arrays for Detection and Discrimination of VOCs Using Phosphonium Ionic Liquid Composites

Sensors, 2020
Herein, we examine two sensing schemes for detection and discrimination of chlorinated volatile organic compounds (VOCs). In this work, phosphonium ionic liquids (ILs) were synthesized and vapor sensing properties examined and compared to phosphonium IL ...
