Doped but Stable: Spirobisacridine Hole Transporting Materials for Hysteresis-Free and Stable Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Pascal Alexander Schouwink, Sanghyun Paek, Cristina Roldán Carmona, Albertus Adrian Sutanto, Hobeom Kim, Marius Franckevicius, Kun-Han Lin, Nikita Drigo, Muhammad Sohail

Four spirobisacridine (SBA) hole-transporting materials were synthesized and employed in perovskite solar cells (PSCs). The molecules bear electronically inert alkyl chains of different length and bulkiness, attached to in-plane N atoms of nearly orthogona ...

Multiquadratic Rings and Walsh-Hadamard Transforms for Oblivious Linear Function Evaluation

Juan Ramón Troncoso-Pastoriza

The Ring Learning with Errors (RLWE) problem has become one of the most widely used cryptographic assumptions for the construction of modern cryptographic primitives. Most of these solutions make use of power-of-two cyclotomic rings mainly due to its simpl ...

Computational parametric analysis of the design of cross-flow turbines under constraints

François Avellan, Sebastián Camilo Leguizamón Sarmiento

The cross-flow turbine is an attractive technology for small-scale hydropower generation thanks to its low capital cost and relatively high efficiency even under partial discharge operating conditions. It has been proposed that this kind of turbine can be ...

Heinz Isler’s twin shell roof in Deitingen – preservation of a ‘timeless wing beat’

Eugen Brühwiler

The Swiss shell pioneer Heinz Isler (1926–2009) fundamentally challenged established shell design methods by introducing original methods of form finding based on gravity. He realised elegant and pure shell forms in reinforced concrete, incarnating the per ...

Planning Supply with 'Opportunity Goods' : Complementing Premium Parts with Select Discount Components

Thomas Alois Weber

In this paper, we introduce the notion of an "opportunity good" as a discount production input that may prove of satisfactory quality upon inspection and otherwise can be returned to the supplier. While in a quality-sensitive setting it is never optimal to ...
