Organic-inorganic hybrid ferroelectrics are an exciting class of molecular materials with promising applications in the area of energy and electronics. Herein, we report the synthesis, ferroelectric and piezoelectric energy harvesting behavior of a 3d metal ion-containing A 4 BX 6 type organic-inorganic hybrid salt [Ph 3 MeP] 4 [Ni(NCS) 6 ] ( 1 ) that crystallizes in the polar monoclinic space group Cc . The P-E hysteresis loop studies on 1 show a remnant ferroelectric polarization value of 18.71 μC cm -2 , at room temperature. Composite thermoplastic polyurethane (TPU) devices with 5, 10, 15 and 20 weight percent (wt %) compositions of 1 were prepared and employed for piezoelectric energy harvesting studies. A maximum output voltage of 19.29 V and a calculated power density value of 2.51 mW cm -3 were observed for the 15 wt % 1 -TPU device. Further, the capacitor charging experiments on the 15 wt % 1 -TPU composite device shows an excellent energy storage performance with the highest stored energies and measured charges of 198.8 μJ and 600 μC, respectively.

Light energy harvesting structures attached to the THYLAKOID MEMBRANES of CYANOBACTERIA and red algae (ALGAE, RED). These multiprotein complexes contain pigments (PHYCOBILIPROTEINS) that transfer light energy to chlorophyll a.
Screening techniques first developed in yeast to identify genes encoding interacting proteins. Variations are used to evaluate interplay between proteins and other molecules. Two-hybrid techniques refer to analysis for protein-protein interactions, one-hybrid for DNA-protein interactions, three-hybrid interactions for RNA-protein interactions or ligand-based interactions. Reverse n-hybrid techniques refer to analysis for mutations or other small molecules that dissociate known interactions.
Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.
A large multisubunit protein complex found in the THYLAKOID MEMBRANE. It uses light energy derived from LIGHT-HARVESTING PROTEIN COMPLEXES to catalyze the splitting of WATER into DIOXYGEN and of reducing equivalents of HYDROGEN.
The transfer of energy of a given form among different scales of motion. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed). It includes the transfer of kinetic energy and the transfer of chemical energy. The transfer of chemical energy from one molecule to another depends on proximity of molecules so it is often used as in techniques to measure distance such as the use of FORSTER RESONANCE ENERGY TRANSFER.
