Potato Micropropagation Medium (PMM) is the growth medium used for in vitro micropropagation of potato tubers. The present study was intended to assess the effect of biofield energy treatment on the physical, thermal and spectroscopic properties of PMM. The study was attained in two groups i.e. control and treated. The control group was remained as untreated, while the treated group was receive...

A new semi-organic nonlinear optical crystal of Glycine Magnesium Chloride (GMC) has been grown by slow evaporation solution growth technique. The crystal system and lattice parameters were determined from the single crystal X-ray diffraction analysis. Fourier transform infrared (FTIR) studies confirm the various functional groups present in the grown crystal. The transmittance and absorbance o...

Abstract Prior to shoulder replacement, the quality of cancellous bone stock humerus head should be evaluated. Thermogravimetric analysis (TGA) has already been utilized assess thermal stability mineral, collected from femoral patients with osteoarthritis and osteoporosis. Our workgroup recently examined parameters rotator cuff undergoing reversed replacement. We hypothesized that TGA would ind...

The present work reports electrochemical synthesis of MgB6 from molten salts using the precursor consists of LiF-B2O3-MgCl2. An attempt has been made to synthesize metastable phase MgB6 crystal by electrolysis method. DTA/TGA studies were made to determine the eutectic point of the melt and it was found to be around 900°C. The electrolysis was performed at 900°C under argon atmosphere, at curre...

A nonlinear optical crystal of gamma glycine was grown by slow evaporation solution growth technique using deionized water and sodium acetate. The functional groups and vibrational frequencies were identified using FTIR spectral analysis. The cell parameters were determined from single crystal X-ray diffraction analysis. Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) w...

A new semiorganic nonlinear optical crystal of bisthiourea nickel bromide (BTNB) was grown successfully by slow evaporation technique using water as solvent. The lattice parameters of the grown crystal have been determined by X-ray diffraction studies. Vibrational spectrum is recorded to determine symmetries of molecular vibrations. Optical absorbance spectrum recorded revealed that this crysta...
