Rational design of carbon shell-encapsulated cobalt nanospheres to enhance microwave absorption performance

Microwave Absorption Characteristics of Carbon Nanotubes

Microwave absorption properties of pyrolytic carbon nanofilm

We analyzed the electromagnetic (EM) shielding effectiveness in the Ka band (26 to 37 GHz) of highly amorphous nanometrically thin pyrolytic carbon (PyC) films with lateral dimensions of 7.2 × 3.4 mm2, which consists of randomly oriented and intertwined graphene flakes with a typical size of a few nanometers. We discovered that the manufactured PyC films, whose thickness is thousand times less ...

Enhanced Microwave Absorption Properties of Intrinsically Core/shell Structured La0.6Sr0.4MnO3Nanoparticles

The intrinsically core/shell structured La(0.6)Sr(0.4)MnO(3) nanoparticles with amorphous shells and ferromagnetic cores have been prepared. The magnetic, dielectric and microwave absorption properties are investigated in the frequency range from 1 to 12 GHz. An optimal reflection loss of -41.1 dB is reached at 8.2 GHz with a matching thickness of 2.2 mm, the bandwidth with a reflection loss le...

Thermodynamics of nanospheres encapsulated in virus capsids.

We investigate the thermodynamics of complexation of functionalized charged nanospheres with viral proteins. The physics of this problem is governed not only by electrostatic interaction between the proteins and the nanosphere cores (screened by salt ions), but also by configurational degrees of freedom of the charged protein N tails. We approach the problem by constructing an appropriate compl...

Synthesis and assembly of core/shell nanospheres.

In this paper, we reported a new simple and effective method, osmotic membrane-assisted self-assembly, for fabricating massive interconnected macroporous silica monolith as catalyst supports. Using the method, we can prepare massive interconnected macroporous silica monolith with homogeneous structures beyond millimeter scale one time. Typically, silica/polystyrene and polystyrene/poly 4-vinyl ...
