The in-situ nano-crystal-to-crystal transformation (SCCT) synthesis provides a powerful approach for tailoring controllable feature shapes and sizes of nano crystals. In this work, three nitrogen-rich energetic nano-crystals based on 5,5'-azotetrazolate(AZT2-) Cr(III) salts were synthesized by means of SCCT methodology. SEM and TEM analyses show that the energetic nano-crystals feature a compos...

At the nano-scale, yield and fracture strengths, for example, have been found to deviate from classical mechanics laws and, therefore, can no longer be inferred from the bulk (large-scale) response or from the literature. Unfortunately, the few existing conventional experimental techniques for assessing mechanical properties at this scale are insufficient, not easily accessible, and generally l...

ÐDevelopments in the ®eld of magnetic materials which show promise for future applications are reviewed. In particular recent work in nanocrystalline materials is reviewed, with either soft or hard behavior as well as advances in the magnetic materials used for magnetic recording. The role of microstructure on the extrinsic magnetic properties of the materials is stressed and it is emphasized h...

Cellulose has a complex, multi-level supermolecular architecture. This natural polymer is built from superfine fibrils having diameters in the nano scale, and each such nanofibril contains ordered nanocrystallites and low-ordered nano-domains. In this review, the nano-structure of cellulose and its influence on various properties of the polymer is discussed. In particular, the ability of nano-s...

In this paper, a teleoperated nano scale object manipulation system is proposed, and requirements of such systems are defined. The system consists of a user interface utilizing visual and haptic displays (macro world), nano-manipulator, controller and sensors (nano world), and teleoperation control and rough to fine imaging and actuation tools (between macro and nano worlds). A home-made Atomic...

Photosynthetic materials form the basis of quantum biology. An important attribute of quantum biology is correlation and coherence of spin states. Such correlated spin states are targets of static magnetic field. In this paper, we report magnetic properties and spectroscopically realizable static magnetic field effect in photosynthetic materials. Two classes of nano-scale assembly of chlorophyl...

A variety of geomaterials, such as cementitious or clay-based materials, has on the nano-scale a layered microstructure that can contain fluid in its nano-porous space. The creep of such nano-scale basic units is what causes the macroscopic creep. Here, one nano-pore whose walls consist of two parallel infinite solid layers interacting through Lennard-Jones potential is studied. The authors eva...

Filamentous networks can be widely found in biomaterials at the microand nano-scales. Some conventional theories may not apply to the materials with dimension at the microor nano-scale. The effects of strain gradient at the micro-meter scale and the effects of surface elasticity and initial stresses/strains at the nano-scale are incorporated into the deformation mechanisms in the analysis of st...
