Self‐Transcendence and Self‐Enhancement Values as Drivers of Eco‐Travel Behavior. Implications for Business Strategies for Eco‐Tourism Sector

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Ecotourism encourages environmentally friendly travel; however, little is known about the underlying value systems influencing travelers' choices and actions. This study uses a mixed‐method methodology that combines post hoc qualitative analysis with a large‐scale quantitative survey to examine the influence of multiple value dimensions on ...

Corporate Governance and Environmental Performance: Does Contingency Theory Affect the Explanatory Power of Theoretical Frameworks?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT There is extensive literature on the relationship between corporate governance (CG) and firms' environmental performance (EP). However, the empirical findings remain somewhat equivocal. A variety of theoretical approaches have been utilised to provide a suitable basis for explaining the causal relationship, including legitimacy theory ...

Turbulent Flame Behavior near Blow-Off in Multi-Stage Swirl Combustors: A Hybrid RANS-LES Study

open access: yesAerospace
Advances in high-performance computing have expanded the use of computational fluid dynamics (CFD) for reacting-flow analysis; however, simulations involving detailed flame kinetics remain computationally intensive for many practical systems.

Blow-Spinning Enabled Precise Doping and Coating for Improving High-Voltage Lithium Cobalt Oxide Cathode Performance

open access: yes, 2019
Lithium cobalt oxide (LiCoO2) possesses an attractive theoretical specific capacity (274 mAh g–1) and high discharge voltage (∼4.2 V vs Li+/Li). However, only a half of the theoretical capacity of LiCoO2 is available in commercialized lithium ion ...

Dynamic‐FLPs Enabled by Orbital Hybridization Tuning: Boosting 100% CO Selectivity for Dilute CO2‐to‐CO Conversion

open access: yesCarbon Energy, EarlyView.
This study, for the first time, constructs photostructured dynamic frustrated Lewis pairs (DFLPs) via a p‐p orbital hybridization regulation strategy, achieving the 100% reduction of low‐concentration CO₂ to CO and breaking the stability‐activity trade‐off.

Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

open access: yesCarbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular

Precision Synthesis of Biomass‐Derived Graphene‐Like Carbon With Tailored Crystallinity via Controlled Flash Joule Heating

open access: yesCarbon Energy, EarlyView.
A dual‐phase flash Joule heating strategy converts pre‐pyrolyzed biomass into structurally tunable carbon materials from waste feedstocks. By decoupling current‐driven thermodynamic input and duration‐dependent kinetic relaxation, the process maps the transition from amorphous carbon to few‐layer turbostratic graphene and turbostratic nanographite ...
