A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Measuring Corporate Alignment With the Circular Economy: a Text‐Based Circularity Index From Mandatory Non‐Financial Disclosures

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) has become a strategic priority for firms, yet empirical assessments of corporate circularity remain fragmented and heavily dependent on structured indicators or self‐reported metrics. This paper proposes a novel, text‐based circularity index derived from mandatory non‐financial statements of large ...

Coal combined-cycle plant with working medium heating in gas-turbine cycle in periodic regenerative heat exchangers

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2009
The authors consider the technique based on application of air heated in periodic regenerative ceramic heat exchangers by coal powder combustion products as a gas-turbine working medium to be rather promising for being studied.

An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Investor Perceptions of Climate Policy: Insights From the US Inflation Reduction Act

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper provides the first event study evidence on how the Inflation Reduction Act's (IRA) dedicated climate provisions reshaped equity valuations in the US carbon‐intensive sectors. Focusing on environmentally sensitive industries (ESI), we analyze cumulative abnormal returns around the four key IRA milestones in 2022–2023.

Green Finance, Digitalization, and Banks' Sustainable Business Model Innovations Toward Net‐Zero Transitions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Financial capital is widely recognized as having the potential to provide investments needed for net‐zero transitions. While recent empirical studies reveal that financial digitalization and fintech have changed Chinese banks' loan portfolios and business models, they stem from credit restrictions on heavily polluting enterprises and from ...

Thermal, environmental, and economic analysis of the gas turbine fogging system

open access: yesResults in Engineering
Ambient temperature can be considered a critical indicator of the efficiency and power production of gas turbines, especially in hot areas, so compressor air inlet cooling systems have been widely used to mitigate this problem.
