摘要:Despite many studies of subsurface imaging of carbon nanotube (CNT)-polymer composites via scanning electron microscopy (SEM), significant controversy exists concerning the imaging depth and contrast mechanisms. We studied CNT-polyimide composites and, by three-dimensional recons...

摘要:Highly reliable field electron emitters were developed using a formulation for reproducible damage-free carbon nanotube (CNT) composite pastes with optimal inorganic fillers and a ball-milling method. We carefully controlled the ball-milling sequence and time to avoid any da...

摘要:Quantifying the nature and extent of the dispersion of nanomaterials in polymer matrices isthe important first step in understanding the relationship between the nanoscale structureand the bulk scale functional performance of nanocomposites. We present here amethodology for using...

摘要:A new method for producing long, small-diameter, single- and few-walled, boronnitride nanotubes (BNNTs) in macroscopic quantities is reported. The pressurizedvapor/condenser (PVC) method produces, without catalysts, highly crystalline, very long,small-diameter, BNNTs. Palm-s...

摘要:Changes in the crystal lattice of palladium nanowires (Pd NWs) upon hydrogen exposure by absorption and interstitial introduction of hydrogen atoms within the matrix can induce swelling of the nanostructure and generate dislocations through the solid that may alter the overa...

摘要:We report on a fully vacuum-sealed compact x-ray tube based on focused carbon nanotube (CNT) field-emission electrons for various radiography applications. The specially designed two-step brazing process enabled us to accomplish a good vacuum level for the stable and reliabl...
