Why Some Firms Perceive Climate Risks and Others Do Not—Evidence From the Logistics Sector
Business Strategy and the Environment, EarlyView.ABSTRACT This study explores how companies perceive risks stemming from climate change as a gradual process, focusing on the logistics sector. It advances research on organizational climate risk perception by integrating perspectives on embeddedness and resource configurations. Based on 41 semi‐structured interviews with representatives of 22 logistics

Carbon Energy, EarlyView.A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.

DETERMINING THE DISTANCE TO THE TARGET IN PASSIVE RADAR OF SURFACE OBJECTS [PDF]
Radio Physics and Radio AstronomySubject and Purpose. While outperforming active radar methods for range, stealth, and energy consumption, passive radar has a significant disadvantage: it cannot determine the target distance and coordinates when only one reference receiving point is ...
