Methodology Synthesis of HBC-RH.The preparation of hydrogel-rice husk derived biochar composite (denoted as HBC-RH) was in accordance with procedures described by Karakoyun et al.[7].
Ozayet al. [9]reported that hydrophilic functional groups such as –OH, −COOH, −NH2, −CONH2, and –SO3H in hydrogel networks grant them the ability to absorb large quantity of water and consequently swell.
These results concur with the findings of other researchers such as Pellera et al. [10]and Zheng et al. [11].

According to Rabinkin et al. [16] the polarization in ferrite is through a mechanism similar to conduction process.
Rezlescu et al. [17] have established a strong correlation between the conduction mechanism and dielectric behaviour of ferrites.
Similar results have been reported by Verma et al. [19, 20] for Ni-Zn ferrites prepared by citrate precursor method.
Parvatheeswara et al [22] for V2O5 added Ni-Zn ferrites.

Then, NiFe2O4 ferrite was silanized with 3-aminopropyltriethoxysilane agent [H2N(CH2)3Si(OC2H5)3] with purity of 97%, whose methodology was described in detail in the work of Santos et al. [11].
Phadatare et al. [14] analyzed the effect of fuel type (PVA, glycine and urea) in the combustion reaction for obtaining nanoparticles of NiFe2O4, and observed by XRD single-phase formation of NiFe2O4 spinel for the three forms of synthesis.
Phadatare et al. [14] analyzed the magnetic behavior of NiFe2O4 nanoparticles synthesized by combustion reaction using different fuels (PVA, glycine and urea), and observed the same ferrimagnetic behavior presented by the samples under study, and saturation magnetization relatively higher, with values of 39, 41 and 44 emu/g, respectively.
Tomitaka et al. [16] evaluated the biocompatibility of NiFe2O4 magnetic nanoparticles in colonies of HeLa cells at a concentration of 100 mg/mL, and reported a cell viability of 77.6% for an exposure of 24h, and 59.4% for an exposure of 48h.

L Zhong et al [8] had develop a composite solder by adding Al2O3 into Sn-0.7Cu solder to improve its properties.
Mohd Salleh et al. [9] reported that mechanical properties of the fabricated composite solder has improved significantly.
It has been reported by Tsao et al [5] and Salleh et al [9] that with the increasing amount of reinforcement, higher hardness properties was resulted.
Due to the limitations of lab XRD, similar phenomenon was encountered by Billah et al. [7] where they could not detect small amount of Bi rich phase additions in Sn–8Zn–3Bi with XRD.

There are several studies [1] [2] [3] [4] [5], claiming that content of Al in the mix of raw materials for aerated concrete and reactivity of silica influence final properties of aerated concrete.
The reason of initial limitation of CSH gel formation from silica and Ca(OH)2 is the fact that Al reduces solubility of silica, which is caused by adsorption of aluminum on the surface of silica.
In the mix of raw materials for aerated concrete with content of reactive silica Al accelerated the crystallization of tobermorite in the direction of the c-axis selectively.
