Tuning the Twist by Molecular Design: A New Strategy for Hexabenzocoronene‐Containing Helical Twistacene

open access: yesChemistry – A European Journal, EarlyView.
An efficient Scholl–based strategy enables precise control of the C–C bond to access the first hexabenzocoronene–containing helical twistacene (NG2). The resulting nanographene shows pronounced helical distortion, high stability, enhanced solubility, and promising redox and optoelectronic properties.

Causal analysis of extreme risk in a network of industry portfolios

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We provide a detailed review of causal dependence within the framework of max‐linear structural models. Such models express each node variable as a max‐linear function of its parental node variables in a directed acyclic graph (DAG) and some exogenous innovation.

Stagewise crop yield prediction with multisource functional indices

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Index insurance design involves integrating weather data, soil moisture, phenology information, and satellite imagery, which presents challenges in data fusion. This article addresses the modelling of multisource functional indices of varying lengths by constructing a stagewise ensemble of sequential models.

Does Environmental Social Governance Performance Promote Green Innovation? Evidence From US Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT I examine the relationship between green innovation and ESG performance using a panel of 4920 US public firms over 2013–2022. Estimates from two‐way fixed‐effects models show that improved ESG performance is positively and significantly associated with greater green innovation. This relationship is mediated by reduced financing constraints and

Corporate Sustainability Transition: Methodological Analysis for a Rating Model

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study introduces a new rating model for the evaluation of corporate sustainability, addressing the inconsistencies and divergences that characterize current ESG assessment systems. The model is hierarchically structured, comprising 99 indicators organized into 19 modules, and is designed to be adaptable by sector and firm size.
