Spongy Diamond

Negatively curved spongy carbon

We describe the production and characterization of a form of nanostructured carbon consisting of fully connected, three-dimensional ~3D! sp networks. This form of carbon is characterized by interconnected thin layers forming a spongy structure with mesoand macroporosity. It is produced by a pulsed microplasma cluster source in the presence of a very low concentration of metallorganic catalyst. ...

Systemic Reactions of Intraosseous (Vascular, Spongy) Anesthesia

Separation of the methods of local anesthesia on diffuse and vascular that we proposed (Petrikas et al.), is related to the safety of dental spongy anesthesia. PURPOSE: To evaluate the systemic complications of dental spongy vascular injection based on publications and our records. Spongy anesthesia containing epinephrine, in each subject causes systemic reactions of the sympathetic or parasymp...

Evolutionary persistence of spongy myocardium in humans.

A15-year-old boy underwent successful cardiac transplantation for severe congestive heart failure. His sister had died at the age of 9 years of undefined congenital heart disease. At the age of 10 years, during a school medical screening, the patient was diagnosed with a cardiomyopathy. At cardiac catheterization, the right ventricle disclosed an increased trabecular pattern, mainly in the regi...

Adenine-functionalized Spongy Graphene for Green and High-Performance Supercapacitors

A simple method is demonstrated to prepare spongy adenine-functionalized graphene (SFG) as interconnected, porous 3-dimensional (3D) network crinkly sheets. Such 3D network structure provides better contact at the electrode/electrolyte interface and facilitates the charge transfer kinetics. The fabricated SFG was characterized by X-ray diffraction (XRD), FTIR, scanning electron microscopy (FESE...

Stem fracture of the cementless spongy metal Lübeck hip prosthesis.

We performed 204 cementless total hip arthroplasties using a fully porous stem made of a cast cobalt-chrome-molybdenum alloy. Five stems fractured at the middle part. Champagne-fluted canals (P<.0001) and low canal fillings 1 cm below the lesser trochanter (P =.02) significantly correlated with stem fractures. Subsequent surgery revealed that all of the proximal parts were surrounded by fibrous...
