Polymethylmethacrylate (PMMA) bone cement is used in orthopedics and dentistry to get primary fixation to bone but doesn’t provide a mechanically and biologically stable bone interface. Therefore, there was a great demand to improve the properties of the PMMA bone cement to reduce its clinical us...
3c). Taking the negatively charged wall of the microchannel as an example, when the liquid contacts the negatively charged wall of the microchannel, the cations in the liquid gather on the wall of the microchannel to form a thin electric double layer (EDL) (0.1 nm-10 nm). Under the ...
Methyl methacrylate (MMA) serves as a fundamental component in the synthesis of poly(methyl methacrylate) (PMMA), a material extensively utilized across a wide array of industries such as furniture, drug delivery systems, and the fabrication of dentures [3]. However, traditional chemical processes ...
Instead, our method is based on reverse patterning with a positive e-beam resist (polymethyl methacrylate (PMMA)) using multiple dry etching methods, thus avoiding lift-off hard masks and ensuring the glass surface remains protected throughout the fabrication process (Methods). Note that this ...
After being transferred to SiO\(_{2}\) /poly-Si wafers, the excess graphene was removed in the sheets using 100 keV electron beam lithography in PMMA followed by an oxygen plasma etch, leaving only the square or ribbons shaped regions. A 20 nm thick layer of Al\(_{2}\)O\(_{3}\...
PMMA has good thermal stability; however, PEKK's thermal stability is superior, making it more resistant to high temperatures [25]. In summary, PEKK offers a unique combination of properties that makes it an attractive material for dental implant applications. It has shown superior biocompatibility...
(PMMA), nanotechnology-based antibiotic transporters such as lipid nanoparticles, silica, and clay nanotubes may improve medication delivery and enable timed release. Antimicrobial characteristics of other non-antibiotic-based nanotechnology cement additives such as chitosan, silver, and dendrimer are also ...
Highly rarefied gas flows through a rough channel of finite length with small bumps appended to its surfaces are investigated, by varying the accommodation coefficient $$\alpha$$ in Maxwell’s diffuse-specular boundary condition, the characteristic size
