Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Revised Rebound Hammer and Pull-Out Test Strength Curves for Fiber-Reinforced Concrete

Advances in Civil Engineering, 2020
Rebound hammer tests and postinstalled pull-out tests are commonly used for evaluating the compressive strength of ordinary concrete, and the strength of concrete is estimated by strength curves.

Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

Journal of Applied Polymer Science, EarlyView.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Large-area fabrication of low- and high-spatial-frequency laser-induced periodic surface structures on carbon fibers

, 2018
The formation and properties of laser-induced periodic surface structures (LIPSS) were investigated on carbon fibers under irradiation of fs-laser pulses characterized by a pulse duration $\tau$ = 300 fs and a laser wavelength $\lambda$ = 1025 nm.

From Compliance to Circularity: A Design‐Led Approach to Recyclable Packaging

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to recyclable packaging is a strategic priority for the Fast‐Moving Consumer Goods (FMCG) sector, aligning with the EU Packaging and Packaging Waste Regulation (PPWR). Adapting to regulatory uncertainty and integrating evolving recyclability criteria require not only technical innovation but also organisational transformation ...

Transforming Procurement: The Dynamic Capabilities and Microfoundations to Buy Circular

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular Procurement (CP) integrates Circular Economy (CE) principles into purchasing decisions to close material loops and retain value across product life cycles. Yet, its adoption remains limited due to persistent barriers within procurement processes.
