Biomaterials for bone tissue regeneration represent a major focus of orthopedic research. However, only a handful of polymeric biomaterials are utilized today because of their failure to address critical issues like compressive strength for load-bearing bone grafts. In this study development of a high compressive strength (~13 MPa hydrated state) polymeric bone composite materials is reported, ...
Although buckling instabilities in elastic solids have been known for a long time, high interest in this phenomenon is relatively recent. The current and prospective applications in flexible electronics, materials with tunable surface properties (adhesion and wettability), responsive photonic and phononic structures, and reinforced nanocomposites led to a surge in the interest in buckling insta...
Particle reinforced composite materials can be characterized as having electrical conductive properties due to their fillers’ material behavior. The paper aims to present a virtual instrumentation layout (Labview design) to aid electrical resistivity changes measurements for iron reinforced polymeric composite samples subjected to an external stress state. A LabJack U12 acquisition board will a...
We present measurements of the low-temperature thermal conductivity of a number of polymeric and composite materials from 0.3 to 4 K. The materials measured are Vespel SP-1, Vespel SP-22, unfilled PEEK, 30% carbon fiber-filled PEEK, 30% glass-filled PEEK, carbon fiber Graphlite composite rod, Torlon 4301, G-10/FR-4 fiberglass, pultruded fiberglass composite, Macor ceramic, and graphite rod. The...
An air-stable LiBH4 polymeric composite was successfully prepared by modifying LiBH4 with a gas-barrier polymer matrix, poly-(methylmethacrylate) (PMMA). The as-prepared LiBH4@PMMA composite started to dehydrogenate at 53 °C with the first main dehydrogenation peak at 116 °C, and 5.2 wt% of hydrogen released at 162 °C within 1 h.
By targeting dendritic cells, polymeric carriers in the nano to lower micron range constitute very interesting tools for antigen delivery. In this critical review, we review how new immunological insights can be exploited to design new carriers allowing one to tune immune responses and to further increase vaccine potency (137 references).
The objective of present work was to develop novel sunscreen creams containing polymeric nanoparticles (NPs) of morin. Polymeric NPs containing morin were prepared and optimized. The creams containing morin NPs were also prepared and evaluated. Optimized NPs exhibited particle size of 90.6 nm and zeta potential of -31 mV. The entrapment efficiency of morin, within the polymeric NPs, was found t...
