Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

open access: yesCytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Bioactive components of red seaweeds: A promising source for therapeutic uses in the future

open access: yesJournal of Biological Research
Seaweed grows and reproduces in intertidal and subtidal regions where photosynthesis is possible due to the available lighting. Marine macroalgae are classified into three main groups according to their pigment content: red algae (Rhodophyceae), green ...

Strategic Prioritization of Environmental, Social, and Governance Goals: A Data‐Driven Efficiency Framework

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Organizations are increasingly required to integrate environmental, social, and governance (ESG) objectives alongside operational performance, yet empirical guidance on how firms should prioritize among ESG activities under resource constraints remains limited.

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

open access: yesDeep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Possible role of microtubules in vesicular transport of matrix protein during sea urchin larval biomineralization

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.
