CHIMIA, 1969 A reinvestigation of the system K2O–UO3 by diffraction methods and i.r. spectroscopy shows that there are two well defined polyuranate phases. Both are based structurally on layers of uranium in hexagonal array, as found in U3O8 and K2U2O7. One polyuranate, isolated in crystalline form is of the diuranate type, with anionic layers 7.045 Å apart, the ...

Potassium and Hypertension [PDF]
Nutrition Reviews, 2009 A recent meta-analysis supports the premise that increased potassium intake may play a role in the prevention and treatment of hypertension. The possible mechanisms by which potassium may act as an antihypertensive and recommendations regarding increasing potassium intake are also discussed.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Feshbach resonances in ultracold K(39)
, 2007 We discover several magnetic Feshbach resonances in collisions of ultracold K(39) atoms, by studying atom losses and molecule formation. Accurate determination of the magnetic-field resonance locations allows us to optimize a quantum collision model for ...

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models
Advanced Functional Materials, EarlyView.Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.
