Article Synopsis
- The offshore Multi-use Setting (MUS) aims to combine marine industrial activities like wind farms and aquaculture to optimize space and resources while addressing global policy priorities.
- A study using expert predictions assessed the potential social and environmental impacts of co-locating seaweed aquaculture with a wind farm, revealing both risks, such as species mortality and stakeholder conflict, and benefits, like improved habitat functionality.
- The findings highlight the complexity and uncertainty in managing MUS, suggesting the need for further integrated assessments and alternative strategies to minimize trade-offs and risks in such ventures.
Article Synopsis
- The growing global population necessitates more animal protein production, and seaweed is emerging as a potential protein source for animal feed.
- A biorefinery approach was developed that processes green seaweed to extract protein and sugars, yielding a protein-rich fraction suitable for monogastric animals, showing better digestibility than whole biomass.
- The extracted sugars can be fermented to produce valuable chemicals like acetone and ethanol, indicating the multifunctional potential of seaweed in sustainable production systems.
The unique chemical composition of seaweeds and their fast growth rates offer many opportunities for biorefining. In this article we argue that cascading biorefinery valorization concepts are viable alternatives to only using seaweeds as carbohydrate sources for the fermentative production of biofuels. However, many challenges remain with respect to use of seaweeds for chemical production, such as the large seasonal variation in the chemical composition of seaweeds.

The following compounds were examined: Tl{Co(CO)(4)}(3) (Ia), [BnMe(3)N](3)[Tl{Fe(CO)(4)}(3)] ([BnMe(3)N](3)[Ib]), Tl{M(CO)(3)Cp}(3) (Ic, M = Cr; Id, M = Mo; Ie, M = W), TlFp(3) (If; Fp = CpFe(CO)(2)), [PPN](2)[Tl(2)Fe(6)(CO)(24)] ([PPN](2)[II]), [Et(4)N](2)[Tl(2)Fe(4)(CO)(16)] ([Et(4)N](2)[III]), [Et(4)N][L(2)Tl{Fe(CO)(4)}(2)] ([Et(4)N][IV]: [IVa](-), L(2) = bipy; [IVb](-), L(2) = en; [IVc](-), L(2) = phen; [IVd](-), L(2) = tmeda; [IVe](-), L(2) = dien), [Et(4)N](4)[Tl(4)Fe(8)(CO)(30)] ([Et(4)N](4)[V]), and TlCo(CO)(4) (VI). The (205)Tl NMR technique was used to probe the dynamic behavior of the Tl-metal cluster complexes [II](2-), [III](2-), and [V](4-) in solution and the formation of Lewis base adducts of [III](-), as well as the possibility of formation of carbonylate anion adducts of Ia, Ic, Id, and If.
