The paper deals with Dielectric Behaviour, Complex Impedance Spectroscopy and Magnetoelectric effect in La_0.7Sr_0.3MnO₃(LSMO) and BaTiO₃ (BT) Composites. The LSMO and BT are synthesized by hydroxide co-precipitation route. The nanocomposites are prepared by two series x LSMO + (1-x) BT + 2 wt % Bi₂O₃, for x = 0.05, 0.1, 0.15 and 0.2 ……series 1. x LSMO + (1-x) BT + 3 wt % Bi₂O₃, for x = 0.05, 0.1, 0.15 and 0.2 ……series 2. and sintered at T_s=1000°C and 1080°C. The composites are termed as LSMO-BT. The paper reports the crystal structure, micro-structural analysis, dielectric constant, complex impedance spectroscopy and magnetoelectric properties of LSMO-BT composites. It has been observed that the ε_r passes through a broad maximum at T ~ 124° C, which is nearly the ferroelectric transition temperature of BT. Both ε_r and ε_rmax increases as x increases from 0.05 to 0.2. The ε_r' and ε_r'' decreases sharply for all the compositions at low frequencies. This feature is typical of the presence of interfacial polarization. The variation of 4πMs is almost linear with x, the 4πMs increases with x as well as sintering aid. The 4πMs of respective compositions reduce as the sintering temperature is increased. The value of α increases for increase in sintering temperature as well as increase in wt % of the sintering aid. The magnitude of α is in the range as reported earlier for composites based on BT.

This paper deals with the adhesion strength of laminated bamboo composites fabricated only from steam-exploded bamboo plates by using a hot-pressing method. The adhesion strength of laminated bamboo composites were evaluated by a short beam bending teats. The effects of molding conditions on the shear strength were examined by changing the molding temperature, time, and pressure. The optimum molding conditions of the laminated bamboo composites are 140°C, 30 min. and 10 MPa among the conditions investigated. The maximum shear strength of the laminated bamboo composites was approximately 46 MPa, and this value is comparable to that of single plate bamboo composites without lamination.
