“…Thus, the vacancies created at some of the O 3 sites effect in an enlargement of the channel radius, thereby increasing of solubility of the material [37]. These changes in the lattice constants and c/a ratio increased from 0.720 (NHAp) to 0.734 (NHAp/PVP) ( Table 1) also indicate the presence of type B carbonate in NHAp [2,47].…”

“…The crystallinity index (CI) is a measure of the perfection and degree of ordering in a sample. It correlates linearly with NHAp crystal size and perfection in the caxis direction, and has obvious influences on hardness and density of the material [2,32,33]. CI is calculated (Table 1) from both FTIR (height method) and XRD (height method) according to the method and formulae used by the researchers [32,[34][35][36].…”

“…The increases in structural parameters (ε, δ and SF) confirm the decrease in the crystalline nature (Table 1). According to de Carvalho Almança Lopes et al [2], the presence of CO 3 2in the HAp structure could be highly important because it could be the main source of distortion of the crystalline network, creating micro-stresses and defects in its vicinity, greatly influencing its solubility. This is achieved in the present study and hence NHAp/PVP has favorable mechanical property and solubility for biomedical applications.…”

“…The biomechanical properties of bone result from its complex structural arrangement of organic (20-30%) (collagen, noncollagenous proteins and lipids), inorganic components (60-70%) and 5% water [1]. Bone inorganic matrix is mainly composed of hydroxyapatite (HAp; Ca 10 (PO 4 ) 6 (OH) 2 ) with 3% to 8% of carbonate content [2]. Mechanical properties of the bone are characterized by HAp compositions, its crystalline structure, morphology, particle size and orientation.…”

The nano-hydroxyapatite (NHAp), NHAp/PEG and NHAp/PVP have been derived from Clam shell by precipitation method. The presence of characteristic FTIR peaks and XRD planes indicates the formation of NHAp. Surface morphology of NHAp, NHAp/PEG and NHAp/PVP appeared to be flake, majorly hexagonal and rod clusters like structure, respectively. Sizes of the NHAp are in nanometer scale and size of NHAp/PVP is the lowest. The poor crystalline nature and high carbonate content presence in NHAp/PVP are assessed through crystallinity index, C/P ratio and CHNS analysis. EDX analysis shows the presence of HAp composition in NHAp. The calculated structural parameters expose that the NHAp/PVP shows favorable mechanical property. Good antibacterial activity is observed in NHAp/PVP against two bacteria strains. Hemolysis study also indicates that NHAp/PVP is non-hemolytic. Formation of complete apatite is found when NHAp/PVP immersed in SBF for 14 days. Thus, the NHAp/PVP derived from Clam shell may be useful for bone-related applications. ARTICLE HISTORY

We present an undergraduate laboratory that utilizes Fourier spectroscopy with two lasers in the visible range to demonstrate the measurement technique. In addition to teaching an important spectroscopic tool, this laboratory exercise deepens the understanding of Fourier transforms. A Michelson interferometer is used to determine the `unknown' wavelength of a green Helium Neon laser beam by scanning the position of a mirror and comparing the number of observed fringes with that from a known-wavelength red Helium Neon laser beam -the reference beam. The data points are recorded electronically using a photodiode and then transformed into frequency space where the unknown wavelength is calibrated against the known wavelength.

To investigate the reinforcing effect of nanoflower‐like hydroxyapatite (NFHA) in resin‐based dental composites, we synthesized a novel NFHA using microwave irradiation (MW), hydrothermal treatment (HT), and sonochemical synthesis (SS). Silanized NFHA was then used as the reinforcing filler in dental resin composites. We characterized the structure and morphology of various HA nanostructures using x‐ray diffraction, scanning electron microscope, and TEM. The mechanical performance of dental resin composites reinforced with silanized NFHA was measured using a universal testing machine. Spherical HA, synthesized through chemical precipitation (CP), served as the control group. One‐way analysis of variance was employed for the statistical analysis of the acquired data. The results demonstrate that the nanoflower morphology significantly was improved mechanical and physical properties. After conducting trials, the NFHA synthesized using MW and HT showed a substantial enhancement in mechanical and physical properties compared to the other structures. Therefore, it can be concluded that NFHA can serve as a novel reinforcing HA filler, providing regenerative properties to resin composites with sufficient mechanical strength.
