Both ultrashort echo-time STEAM and MEGA-PRESS-edited spectroscopy were used to validate noninvasive quantification of vitamin C (ascorbate) in the developing rat brain, where changes in ascorbate concentration have been reported. Despite strong overlap wi ...
We study phase separation in a deeply quenched colloid-polymer mixture in microgravity on the International Space Station using small-angle light scattering and direct imaging. We observe a clear crossover from early-stage spinodal decomposition to late-st ...
Hydrocarbon mass transfers to the atmosphere and water column drive the early weathering of oil spills and also control the chemical exposures of many coastal wildlife species. However, in the field, mass transfer rates of individual hydrocarbons to air an ...
A nanoreactor based on mesoporous silicates is described for efficient tryptic digestion of proteins within the mesochannels. Cyano-functionalized mesoporous silicate (CNS), with an average pore diameter of 18 nm, is a good support for trypsin, with rapid ...
In the last past years, many promising applications of nanoparticles in quantum electronics such as nanocrystal memories, chemical sensors or nanodevices based on single electron tunneling and Coulomb blockade effects have attracted much attention. Nanopar ...
Insight into the conformations and aggregation of alginic acid was gained by measuring its diffusion coefficient at very dilute concentrations using fluorescence correlation spectroscopy. Both the pH and ionic strength (I) had an important influence on the ...
The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...
The invention features a triblock copolymer including a hydrophilic block a hydrophobic block and a positively charged block capable of reversibly complexing a negatively charged molecule, e.g., a nucleic acid, wherein the hydrophobic block is disposed bet ...
Gold nanoparticles with hydrophobic surface have been deposited on a silicon substrate chemically patterned by reactive ion etching through a stencil mask and chemical vapour deposition of alkyl silanes. After deposition by dipping and adequate rinsing, th ...
We describe the first case of efavirenz-induced urolithiasis in a 47-year-old HIV-positive patient. Urinary obstruction led to pyelonephritis and septic shock, requiring emergency ureteral catheterisation. The subsequent clinical course was favourable, all ...
