An investigation of the effect of sodium dodecylbenzenesulfonic acid (SDBS) on both growth rate and morphology of borax crystal has been carried out.  This experiment was carried out at temperature of 25 °C and relative supersaturation of 0.21 and 0.74 under in situ cell optical microscopy method.  The result shows that SDBS inhibits the growth rate and changes the morphology of borax crystal.   Keywords: Borax; growth rate; crystallization, SDBS

Biological material has been documented to produce an external magnetic field that radiates out. There have been several papers documenting the magnetic fields produced by steady currents in the body. The most notable was published in 1980 by Cohen et al. where the human hair follicle was used as sentinel and biophysically evaluated via sophisticated equipment such as a double planar Superconducting Quantum Interference Devices (SQUID). Most recently, in 2019 Cohen’s work was duplicated by Khan,S by also using double-planar gladiometers. Of interest to this manuscript is that since the introduction of anovel optical microscopy method in 2016 by Scherlag BJ et al is that numerous papers have been introduced in the literature now identifying intrinsic biomagnetic properties of the follicle such as penetration through glass barriers. In this manuscript, a concept of biomagnetic fields by the concave part of the human hand transferring energy to hair follicles is introduced, this was accomplished by using a novel optical microscopy method, in other words, the hair follicle is not limited to radiate out biomagnetism; but also, to receive externally radiated biomagnetic fields from a body part. This magneto receptive property is herein introduced.

he growth rates of borax crystals from aqueous solutions in the (001) direction at various relative supersaturations were measured using in situ cell optical microscopy method. The result shows that the growth mechanism of the (001) face of borax crystal at temperature of 20 °C is spiral growth mechanism.   Keywords: Growth mechanism, borax.
