Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes
Advanced Science, EarlyView.In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

Sustainability and Scope: A Comparative Study of Discretion Making for Sustainability
Business Strategy and the Environment, EarlyView.ABSTRACT The measurability of sustainability is a subject of ongoing debate. Discretion is an important antecedent to such valuation yet remains largely unaddressed. Thus, we conduct a cross‐case study of four organizations, finding differences between product and service firms in how they define their sustainability discretion, which is shaped by and,

Anomalous Behavior of a Solid Rocket Motor Nozzle Insert During Static Firing Test
Journal of Aerospace Technology and Management, 2016 This paper presents the study and development of a firing test used to evaluate the behavior of a solid rocket motor. The motivation for the development of a subscale solid rocket motor with end burning propellant grain geometry arose from the need to ...
