Hydroxyapatite nanorods aligned with ultrahigh crystallinity and high-yield were successfully synthesized through a hydrothermal approach. In this experiment, a new composition of cetyltrimethylammonium bromide ((CH3(CH2)15N+(CH3)3Br-) was designated as CTAP)/Ca(NO3)2/(NH4)2HPO4/NaOH and distilled water under hydrothermal condition, to synthesize single crystalHAp nanorods with diameter of 20 ±...

various materials and techniques have been used in the treatment of periodontal disease to achieve regeneration of lost periodontal tissues including cementum, periodontal ligament (pdl) and alveolar bone. the composition, regenerative potential, application and therapeutic characteristics of several regenerative materials have been evaluated in the present study

This review discusses recent developments in the field of nanosized biomaterials and their use in tissue regeneration approaches. The aim is to provide an overview of the research focused on nanoparticle-based strategies to stimulate regeneration. In particular, nanoparticles improve the regenerative capabilities of biomaterials offering ways to control surface and mechanical properties. Moreov...

High-resolution transmission electron microscopy (HRTEM) has shown to be very powerful for solving three-dimensional (3D) structures of unknown crystals. HRTEM has a unique advantage over diffraction for solving structures. Crystallographic structure factor phases, which are lost in diffraction can be directly obtained from HRTEM images. For the determination of a 3D crystalline structure by HR...

An innovative methodology was implemented for removing arsenic from aqueous solution by developing successive biosorption experiments. Considering the high affinity of As oxyanions toward Fe(III) oxides, Fe(II) first conducted using nine biomaterials—aquatic and terrestrial invasive species, biowastes, local plants. Pistia stratiotes, an alien species presenting highest concentration adsorbed F...

The effects of thickness and tilt angle are studied numerically on experimental high-resolution transmission electron microscope (HRTEM) images of a wedge-shaped metal oxide crystal. For sufficiently thin and well-aligned crystals, the amplitudes and phases of the Fourier transforms of the HRTEM images are essentially the same as the crystallographic structure factors. For tilted crystals, the ...

We present an application of the digital image correlation (DIC) method to highresolution transmission electron microscopy (HRTEM) images for nanoscale deformation analysis. The combination of DIC and HRTEM offers both the ultrahigh spatial resolution and high displacement detection sensitivity that are not possible with other microscope-based DIC techniques. We demonstrate the accuracy and uti...

115 Abstract This article introduces the use of in situ high-resolution transmission electron microscopy (HRTEM) techniques for the study and development of nanomaterials and their properties. Specifically, it shows how in situ HRTEM (and TEM) can be used to understand diverse phenomena at the nanoscale, such as the behavior of alloy phase formation in isolated nanometer-sized particles, the me...
