Giovanni Antonio Scopoli's De Hydrargyro Idriensi Tentamina (1761): Mercury Mining, Mercurialism, and Preventive Reasoning in Eighteenth‐Century Occupational Medicine

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Giovanni Antonio Scopoli (1723–1788), a physician‐naturalist of the Enlightenment, is primarily remembered for his contributions to botany and entomology. Less attention has been paid to his medical work De hydrargyro Idriensi Tentamina physico‐chymico‐medica (1761), written during his fifteen years of service as physician at the mercury mines

Connecting Thoughts and Actions: A Managerial Process Model on Circular Business Model Innovation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Addressing environmental grand challenges such as resource scarcity requires circular business model innovation (CBMI) that enables firms to efficiently close and slow resource cycles through novel activity systems. Drawing on a grounded theory approach based on 59 in‐depth interviews with top managers from Swiss SMEs, we developed a process ...

Release Pattern of Light Aromatic Hydrocarbons during the Biomass Roasting Process

open access: yesMolecules
Roasting is an important step in the pretreatment of biomass upgrading. Roasting can improve the fuel quality of biomass, reduce the O/C and H/C ratios in the biomass, and provide the biomass with a fuel quality comparable to that of lignite.

Effectiveness of Sustainability Rating Scales in Dual‐Labeling: The Role of Eco‐Label Familiarity in Consumer Responses

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Eco‐labels and sustainability rating scales are widely used to communicate product sustainability, yet it remains unclear whether combining these signals enhances or undermines consumer responses. Drawing on signaling theory, this study examines how eco‐label familiarity and the presence of a sustainability rating scale jointly shape consumer ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.
