Programming the hierarchical self-assembly of small molecules has been a fundamental topic great significance in biological systems and artificial supramolecular systems. Precise highly programmed can produce architectures with distinct structural features. However, it still remains challenge how to precisely control pathway desirable way by introducing abundant information into limited molecular backbone. Here we disclose strategy that directs sodium thioctate, molecule origin, ordered...
The Inflation Reduction Act (IRA) in the United States provides unprecedented incentives for deploying low-carbon hydrogen and liquid fuels, among other low-greenhouse gas (GHG) emissions technologies. To better understand prospective competitiveness of or negative-carbon fuels under IRA early 2030s, we examined impacts provisions on costs producing synthetic fuel made from natural gas, electricity, short-cycle biomass (agricultural residues), corn-derived ethanol. We determined that, with...
A series of triptycene-containing sulfonated polysulfone (TRP-BP) materials was prepared via condensation polymerization, and the desalination membrane-relevant fundamental water salt transport properties (i.e., sorption, diffusion, permeability coefficients) polymers were characterized. Incorporating triptycene into increased content material compared to that do not contain triptycene. No significant difference in sorption observed between TRP-BP membranes other membranes, suggesting...
Metal–organic frameworks (MOFs) are a promising class of functional materials with applications in catalysis, separations, electronics, and drug delivery, among others. Despite range techniques utilized for MOF synthesis, generalizable scalable approach has yet to be developed producing MOFs without using environmentally damaging organic solvents. Here, we look at synthesis as reaction an aqueous medium propose new methods measuring conversion selectivity. We show that controlling reactant...
Ag-loaded ZnO mesocrystals with Fe3+ doped (FAZ) can be quantity-produced through an atmospheric self-induction synthesis method. This method avoids the use of a high-pressure instrument for mesocrystal catalysts. Compared traditional Ag-ZnO catalysts, threshold wavelength 1FAZ was shifted to full visible light region and absorbance catalyst in increased more than 300%. The content iron ion found significant photocatalytic efficiency FAZ mesocrystals. experimental results demonstrated that...
To optimize the productivity of ion exchange membranes used in electric field-driven separation processes, an understanding relationship between membrane structure–property metrics and a measure is necessary. The factor commonly indicator efficacy, as outlined this review, it can be related to intrinsic sorption diffusion selectivity properties membrane. Doing so connects key theories that describe transport, connection facilitates analysis implications these on separations. process...
Membrane-based desalination processes are used widely to address increasing global demand for purified water. To continue meet demand, advanced and highly selective membranes needed effectively efficiently purify water that is increasingly contaminated saline. A general lack of fundamental structure–property relationships frustrates the development these membranes. Advanced polymer synthesis capabilities enable precise molecular control over position functional groups on a backbone could be...
Understanding the effects of polymer chemistry on membrane ion transport properties is critical for enabling efforts to design advanced highly permselective exchange membranes water purification and energy applications.
Little is known about how aqueous electrolyte exposure affects hydrated polymer relative permittivity and state of water properties. Increasing NaCl solution concentration (0.01, 0.1, 1.0 mol/L) caused a cross-linked glycidyl glycerol methacrylate-based copolymer to osmotically deswell ion sorption increase opposite electrostatic theory Maxwell Garnett equation predictions. The presence, due salt equilibration, ions in the drove an static compared that pure water-equilibrated equivalent...
We have carried out neutron and magnetic studies on Nd/sub 2/Fe/sub 17-x/T/sub x/ (T=Si, Mn) alloys. The unit cell of the compounds contracts with both Si Mn substitution. atoms avoid 6c site, prefer 18h site strongly, fill 9d steadily 18f only at relatively high concentration. sites but while slowly. occupancies appear to be dominated by crystal environment are steric considerations. Curie temperature compound 17/ increases significantly substitution is affected slightly Although increasing...
A series of Nd2Fe17−xMnx solid solutions with x values between 0 and 6 were prepared analyzed using magnetic measurements, neutron diffraction, Mössbauer spectroscopy. All the samples crystallized in Th2Zn17−x-type rhombohedral structure. The lattice parameters unit cell volumes decrease increasing manganese content up to ∼x equal 2, then increase for higher content. magnetizations is paramagnetic at room temperature greater than 3. Curie maximum 0.5 decreases a rate ∼10° per substituted 3,...
