Porous Poly(ε‐Caprolactone)/Keratin Composite Scaffolds: Structural Features, Degradation Behavior and Cell‐Material Interactions

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Porous scaffolds based on pure poly(ε‐caprolactone) (PCL) and on biocomposite made of PCL and feather‐extracted β‐keratin (FK) were fabricated by salt‐leaching method. FK was incorporated into PCL to address the limited bioactivity and hydrophobic nature of PCL, with the aim of improving cell–material interactions for bone tissue engineering ...

An innovative thiourea gold leaching process

open access: yesHydrometallurgy, 1998
The aim of this experimental work was devoted to the preliminary evaluation of the feasibility of thiourea leaching for the extraction of gold from a domestic gold-bearing ore 4 grt Au, at laboratory scale. The study has permitted identification of the influence of temperature, leaching agent concentration, pulp density and leaching time on the gold ...

Host Cell Protein Challenges in Antibody Processing: Insights Into Persistence and Mitigation Strategies

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Persistence of HCPs remains a major purification challenge in biopharmaceutical manufacturing with direct consequences for product quality, patient safety, and regulatory compliance. Over the last two decades, deeper insights into the mechanisms driving HCP persistence have clarified why certain proteins evade removal during purification ...

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

open access: yesBMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by

Digital Transformation on Green Operational Performance: Evidence From the E‐Waste Firm's Perspective

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Digital transformation (DT) is increasingly recognised as essential for improving environmental performance in process‐intensive and hazardous sectors; however, the mechanisms by which digitalisation translates into green operational performance (GOP) and environmental accountability remain insufficiently investigated, particularly in ...

Towards a Socially Inclusive Circular Economy: Evidence From Social Enterprises in Low‐ and Middle‐Income Countries

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular economy (CE) and social entrepreneurship (SE) are increasingly recognised as critical pathways for sustainable development, yet CE research often underplays social inclusion, particularly in low‐ and middle‐income countries (LMICs).

Achieving Immanent Organizational Ethics: Managing Paradoxical Tensions in Packaging

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Firms face strategic tensions in packaging materials through their conflicting but complementary social, environmental and economic goals in achieving sustainability. Reducing and repurposing plastics, glass, paper and cardboard in agriculture, horticulture and aquaculture is proving a challenge.
