Light-activated photosystem II (PSII) carries out the critical step of splitting water in photosynthesis. However, PSII is susceptible to light-induced damage. Here, results are presented from a novel microbial electro-photosynthetic system (MEPS) that uses redox mediators conjunction with an electrode drive electron transport live Synechocystis (ΔpsbB) cells lacking PSII. MEPS-generated, light-dependent current increased light intensity up 2050 μmol photons m–2 s–1, which yielded delivery...
A system called AUDACity was developed and demonstrated for continuously delivering ~100 g per day of direct air-captured (DAC) CO2 into aqueous alkaline solutions within a 4.2 m2 outdoor raceway pond in moisture-driven process. Anion-exchange resin particles contained elongated mesh tube packets were found to reduce drying loading time ~4-fold over larger bags, which allowed the sorbent clump surface area exposed air, as measured closed loop wind tunnel. The used cultivating cyanobacterium...
Proteins and peptides fold into dynamic structures that access a broad functional landscape; however, designing artificial polypeptide systems is still great challenge. Conversely, DNA engineering now routinely used to build wide variety of 2D 3D nanostructures from hybridization based rules, their diversity can be significantly expanded through site specific incorporation the appropriate guest molecules. Here we demonstrate new approach rationally design nucleic acid–amino acid complexes...
Proteins have evolved to carry out nearly all the work required of living organisms within complex inter- and intracellular environments. However, systematically investigating range interactions experienced by a protein that influence its function remains challenging. DNA nanostructures are emerging as convenient method arrange broad guest molecules. flexible methods needed for arranging proteins in more biologically relevant 3D geometries under mild conditions preserve function. Here we...
PNA is hybrid molecule ideally suited for bridging the functional landscape of polypeptides with structural diversity that can be engineered DNA nanostructures. However, more challenging to work in aqueous solvents due its hydrophobic nature. A solution phase method using strain promoted, copper free click chemistry was developed conjugate fluorescent dye Cy5 2 bifunctional strands as a first step toward building cyclic PNA-polypeptides arranged within 3D nanoscaffolds. nanocage designed...
Direct Air Capture, the chemical separation of carbon dioxide (CO2) from air, is considered a necessary approach to generate negative emissions and in turn limit global warming, though energetic monetary costs must continue decline meet needed gigaton scale. The promise energy-efficient continuous membrane has only recently been investigated with development facilitated transport novel electrochemically driven methods. This work demonstrates potential for pumping CO2 air using commercial...
