How founders' values enable business model innovation in new ventures: The case of Magnum Photos

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary This study explores why and how founders' values lead them to design novel business models. To address these questions, we conducted a historical case study of Magnum Photos, a photo agency whose novel business model revolutionized magazine photography in the mid‐20th century.

Stretchable Water‐Repellent PEDOT:PSS‐Impregnated Polyurethane Nanofiber Mats for Electromagnetic Interference Shielding

open access: yesSmall, EarlyView.
Poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) is impregnated onto an ultrastrong electrospun polyurethane (PU) nanofiber mat, resulting in the fabrication of an electrically conductive, robust, and stretchable EMI shield. This robust textile, stretchable up to 207% with 86% elastic recovery, shows a normalized EMI shielding effectiveness ...

Enhanced Electromagnetic Wave Absorption in Mapbi3 Hybrid Perovskite Through a Defect‐Tunable Green Synthesis

open access: yesSmall Structures, EarlyView.
Mechanosynthesis allowed synthesizing and providing large amount of high‐quality MAPbI3 powders with defects tuned by grinding time. Mechanosynthesized MAPbI3 for 4 h dispersed in a polymeric matrix led to a marked enhancement in dielectric loss at 11.4 GHz, which makes this green synthesis approach promising for producing hybrid perovskites with ...
