El-Shetehy, Mohamed ; Moradi, Aboubakr ; Maceroni, Mattia ; Reinhardt, Didier ; Petri-Fink, Alke ; Rothen-Rutishauser, Barbara ; Mauch, Felix ; Schwab, Fabienne

In: Nature Nanotechnology, 2020, p. 1–10

In plants, pathogen attack can induce an immune response known as systemic acquired resistance that protects against a broad spectrum of pathogens. In the search for safer agrochemicals, silica nanoparticles (SiO2 NPs; food additive E551) have recently been proposed as a new tool. However, initial results are controversial, and the molecular mechanisms of SiO2 NP-induced disease resistance...

Advances in porous organic polymers for efficient water capture

Byun, Yearin ; Je, Sang Hyun ; Talapaneni, Siddulu Naidu ; Coskun, Ali

In: Chemistry – A European Journal, 2019, vol. 25, no. 44, p. 10262–10283

Desiccant driven dehumidification for maintaining the proper humidity levels and atmospheric water capture with minimum energy penalty are important aspects in heat pumps, refrigeration, gas and liquid purifications, gas sensing, and clean water production for improved human health and comfort. Water adsorption by using nanoporous materials has emerged as a viable alternative to...
