Aluminum nanoparticles (Al NPs) have long been utilized for high-density energy storage and small-scale hydrogen production. The enthalpy of reaction for the formation of aluminum oxide (-1675.7 kJ mol-1) is a major reason for aluminum’s [...]
Aluminum metal, with its light weight, high energy density, and ready availability is particularly valued in energetic application such as fuel additives. Aluminum nanoparticles (Al NPs) offer the advantage of accessing this high energy content [...]
Plasmonic nanoparticles play an important role in biomedical applications today as they can serve as superior optically-stable bioimaging agents, be employed in biosensor devices for the early diagnosis of diseases, and exhibit promising results for [...]
We hypothesize that M287 encapsulated in PLA-PEG will provide for its slow controlled release and thus enhance its capacity to induce immune responses in mice.
There are no reports on the synthesis of single crystalline micrometric magnetite with superparamagnetic behavior. The literature mainly refers to micrometric particles obtained by nanoparticle agglomeration. The major disadvantage of magnetic microparticles composed of clusters [...]
Methods continue to be developed for improving the size and shape uniformity of Au nanoparticles (NP), however, fabricated NPs tend to be faceted and not highly spherical. We present results that show that the faceted [...]
Hepatocellular carcinoma is the third leading cause of cancer deaths in worldwide. In this study, multi-functional micelles loaded with doxorubicin (Dox) and labeled with the radionuclide rhenium-188 (188Re) were developed to provide the combination of [...]
New magnetic nanomaterials with tunable properties were produced using three procedures. (1) Mixtures of polyvinyl alcohol (PVA) solutions and ferric oxide  based ferrofluid were prepared and also electrospun with the purpose of synthesizing magnetic [...]
