The preparation of CdS was performed by the precipitation method using ethylenediamine as template and tetrahydrofuran, acetonitrile or butanol as organic solvents. The formation of CdS with hexagonal structure was observed by XRD due to the template effect. FTIR studies showed that the amount of the template linked to the surface of the CdS depends on the organic solvent used. TEM observations evidenced the formations of CdS nanofibers and the EDS analysis show the chemical composition of the surface. The photocatalytic activity of CdS nanofibers under blue light irradiation was strongly influenced by the amount of ethylenediamine template on the nanofiber surface. It was observed that when the amount of the template on the samples diminishes by the heat treatment, the photocatalytic activity is affected. The role of the ethylenediamine template in the mechanism for the H2 production reaction is discussed.

We prepared an organically templated magnet, (H)VPOOH (H = diprotonated ethylenediamine), hydrothermally and characterized its crystal structure by powder X-ray diffraction and Fourier-transform infrared spectroscopy, and its physical properties by magnetization, specific heat and nuclear magnetic resonance measurements and density functional theory calculations. (H)VPOOH consists of uniform chains of V (d, = 1) ions and exhibits Haldane magnetism with spin gap = 59.3 K from the magnetic susceptibility () at = 0.

Black-spot shell disease is an unresolved disease that decreases pearl quality and threatens pearl oyster survival. In previous studies, the bacterium Tenacibaculum sp. strain Pbs-1 was isolated from diseased Akoya pearl oysters Pinctada fucata, and a rapid, specific, and sensitive loop-mediated isothermal amplification (LAMP) assay for detecting this pathogen was established.

Mono- and bis-salen functionalised [2]rotaxanes have been synthesised from the esterification of [2]rotaxanes containing phenol-terminated threads (salen=N,N'-bis(salicylidene)ethylenediamine). The [2]rotaxanes have general formula [RH][CrNiF(OCBu)], where [RH] is a thread with a central secondary ammonium site that templates a [CrNiF(OCBu)] ring. The threads are terminated at one or both ends by carboxylic acid functionalised salen groups.
