Various less-toxic substitutes for the Pb2+-based perovskites have been proposed, of which Sn2+-based metal halide perovskites (namely, Sn-PVSKs) hold the best prospects because of their optoelectronic properties comparable to those of the Pb analogues. Nevertheless, the intrinsic instability and unfavorable crystallization of Sn-PVSKs place restrictions on both the device performance/durability a
This article analyzes administrative practices in relation to the emergence of novel technologies. “Smart mobility” is an umbrella term used to denote the potentially disruptive changes in the transport sector relating to automatization, digitalization, and the platform economy. While this development is largely driven by industry, public administrations are engaging in a number of processes where
This book focuses on Public Procurement for Innovation. Public Procurement for Innovation is a specific demand-side innovation policy instrument. It occurs when a public organization places an order for a new or improved product to fulfill certain needs that cannot be met at the moment of the order. The book provides evidence of the potential benefits to public and private actors from the selectiv
The possibility of prosecuting serious international crimes before domestic foreign courts when territorial courts are unwilling and unable to perform this function and international criminal tribunals with suitable competences are unavailable has been intensively debated since the time of the Spanish arrest warrants against Pinochet. The African disapproval of decisions by European courts to exer
This chapter provides an attempt to enable a productive conversation between the budding, interdisciplinary research field of celebrity studies, humanitarianism, and activism and feminist international political economy scholarship. It focuses on the Same Sky shopping initiative – a New York-based ethical trade and shopping initiative supported by a philanthropic foundation with the same name. The
ad transport of dangerous goods is due to its inherent risk associated with a potential impact far higher than the small volumes might suggest, and has therefore been the target of numerous ITS-related initiatives. However, there are few indications of actual working ITS solutions for dangerous goods. In this paper we conduct an empirical investigation of past projects and research to analyze the
Gas phase polyethylene reactors are able to produce several different grades of polymer. Adapting to market conditions requires grade transitions, associated with costs in terms of raw material and temporary production of lower priced off-specification products. In this paper, both stationary production and dynamic grade transitions are optimized to maximize profit, i.e., economic process optimiza
Objective: To evaluate long-term oncological outcome and surgical quality of robotic radical hysterectomy for cervical cancer. Methods: Consecutive women with stage IA2 to IIA operated between March 2006 and May 2012 with a robotic radical hysterectomy and pelvic lymphadenectomy were prospectively followed up until five years after surgery or until death. Details regarding clinical results, recurr
A general mixed initial-boundary value problem for a non-local hyperbolic equation, relevant for the study of the propagation of transient electro-magnetic waves in flat slabs, consisting of dispersive stratified complex media, and excited by incident plane waves, is treated. Theorems regarding unique solvability and causality are presented and proved by a time domain method similar to the one use
Objective. Most methods for measurements of the regional cerebral blood flow are unable to provide absolute blood flow values. Until now interest has been focused on measurement of the gray matter blood flow, while the white matter blood flow has been rather neglected. The aim of the present project was to develop and evaluate an improved method for reliable tomographic measurements of absolute wh
