Scalable engineered blood vessels would improve clinical applicability. Using easily sizable 3D-printed guides, rings of vascular smooth muscle were created and stacked into a tubular form, forming a vascular graft. Grafts can be sized to meet the range of human coronary artery dimensions by simply changing the 3D-printed guide size.

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes. Many viruses self-assemble into a fully functional unit using the infected host cell to...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

CRISPR-associated protein Cpf1 can be guided by a specially designed CRISPR RNA (crRNA) to cleave double-stranded DNA at desired sites, generating sticky ends. Based on this characteristic, a DNA assembly standard (C-Brick) was established, and a protocol detailing its use is described here.
FAQs
Alternating membrane types creates repeating compartments that guide oppositely charged ions through different selective barriers. This arrangement maintains the intended sequence of high- and low-salinity solution compartments, allowing ion movement across the stack to contribute to an electrochemical potential. The membrane order is therefore central to converting the salinity difference into collectable electrical current.
The difference between high- and low-salinity solutions drives ions down a concentration gradient through the exchange membranes. That directed movement produces an electrochemical potential across the assembled stack, which electrodes collect as current. Maintaining distinct solution compartments is important because the gradient provides the driving force for energy conversion.
Accurate membrane alignment preserves the intended compartment sequence and fluid pathways, while sealed interfaces help prevent solution leakage between compartments or outside the stack. These assembly conditions limit fluid-management problems and electrical losses. As a result, careful mechanical construction supports more reliable ion transport and improves the stack’s ability to produce usable current.
A basic assembly sequence places cation- and anion-exchange membranes in alternating order, establishes the repeating high- and low-salinity compartments, aligns the membrane layers, and forms controlled fluid pathways. The interfaces are then sealed to limit leakage. These steps connect membrane organization, solution handling, and electrical collection into one functioning stack.
The critical construction elements are the cation- and anion-exchange membranes, the high- and low-salinity solution compartments, the fluid pathways, the sealed interfaces, and the electrodes that collect current. Their positions and relationships must remain controlled during assembly. Poor alignment or leakage can disrupt solution separation and increase electrical losses.
A properly assembled stack provides a platform for studying salinity-gradient power, membrane performance, and fluid management. It also supports engineering research on scalable renewable-energy systems. By controlling membrane arrangement, solution pathways, and sealing, researchers can examine how assembly choices affect ion transport, electrochemical potential, current collection, and overall stack operation.
