Evaporation of Metals during the Thermal Treatment of Oxide Nanomaterials in Cellulose-Based Matrices

Like conventional material products, waste is the last stage of the life cycle of engineered nanomaterials, which are then incinerated or stabilized before disposal. However, because of their special physical characteristics, the fate of the thermally trea ...

Reusability of filtering facepiece respirators after decontamination through drying and germicidal UV irradiation

David Vernez, Véronique Michaud, Guillaume Suarez, Kiattisak Batsungnoen

Introduction During pandemics, such as the SARS-CoV-2, filtering facepiece respirators plays an essential role in protecting healthcare personnel. The recycling of respirators is possible in case of critical shortage, but it raises the question of the effe ...

One-dimensional facile growth of MAPbI(3) perovskite micro-rods

Mohammad Khaja Nazeeruddin, Zubair Ahmad

One-dimensional microrods (4-5 mm) of PbI2 and CH3NH3PbI3 (MAPbI(3)) with unique structural and morphological properties have been grown at room temperature. X-ray diffraction (XRD) patterns of both types of micro-rods exhibit a hexagonal system (P3m1(164) ...

Effect of annealing temperature on the performance of printable carbon electrodes for perovskite solar cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Zubair Ahmad

Perovskite solar cells (PSCs) with mesoporous TiO2 electron transport layers have reached > 22% efficiency at laboratory scale ( < 1 cm(2)), however, these layers are fabricated using spin-coating, which is not conducive to large-scale or high throughput f ...

Rapid, Robust, and Relevant (R3) Reactivity Test for Supplementary Cementitious Materials

Karen Scrivener, François Henri Avet, Ruben Anton Snellings, Xuerun Li

Although supplementary cementitious materials (SCMs) are now commonly accepted and widely used, consensus has not been reached for methods to test their chemical reactivity. A multitude of test methods exist but often fall short on one or more of the key f ...
