Perovskite materials are crucial in a variety of important technological applications. Using quantum-mechanical simulations, we have computationally investigated ferroelectric materials for applications in computer memory and piezoelectric devices. We have determined that tetragonality of perovskite ferroelectrics, which is crucial for high piezoelectric performance, exhibits a quadratic depend...

Two fungal species commonly found in indoor environments, Penicillium commune and Paecilomyces variotü, were cultivated on pine wood and on a combination of gypsum board and mineral wool. Air from the cultures was adsorbed on Tenax TA and analysed using thermal desorption-cold trap injection gas chromatography. Identification of the produced volatile metabolites was performed by mass spectromet...

Molecularly imprinted polymers (MIPs) have been playing an increasingly important role in volatile organic compounds (VOC) sensing for air quality control. The unique feature of these materials is their biomimetic molecular recognition functionality. Theoretical chemistry can advance our ability to design and synthesize new MIPs with specific functions, providing valuable insight into the syste...

We have designed and synthesized highly porous COFs and MOFs as functional architectures that are capable of capturing volatile TICs. In parallel, we have explored novel crystalline porous materials that have reactive sites and functionalities, which can be controlled by an external stimulus. We demonstrated that reticular chemistry facilitates the design and synthesis of new robust COFs, as we...

Laboratory analyses of lunar samples provide a direct means to identify indigenous volatiles and have been used to argue for the presence of Earth-like water content in the lunar interior. Some volatile elements, however, have been interpreted as evidence for a bulk lunar mantle that is dry. Here we demonstrate that, for a number of lunar pyroclastic deposits, near-infrared reflectance spectra ...

Introduction April 26, 1986, will go into history as the date when the 4th reactor of the Chernobyl Nuclear Power Station exploded causing radioactive contamination of a wide area practically in all Europe. The initial explosions and heat carried volatile radioactive materials up to 1.5 km height from where these materials were transported over large territories. Plumes containing numerous quan...

printing and copying centers have been implicated as an emission source of pollution, and affecting air quality in closed environments. the aim of this study was to measure the btex compound (benzene, toluene, ethyl benzene, and xylenes), and the intensity of electromagnetic fields and the uva ray in photocopy centers in the hamadan city. this descriptive study was done on 45 printing and copyi...

Verticillium wilt is a serious disease of pistachio caused by Verticilliumdahliae. Control of the disease is difficult due to soil borne nature of the causal agent. Verticillium wilt has been biologically controlled by Trichoderma spp. In the present study, Trichoderma spp. was isolated from soils of pistachio orchards and their effect was investigated on radial growth of Verticillium dahliae b...

PURPOSE Although there is no clinical evidence of nephrotoxicity with the volatile anesthetics currently used in general anesthesia, a better agent should be needed in terms of preserving postoperative renal function in living kidney donors who have only single remaining kidney. The purpose of the current retrospective, single-center study was to evaluate and compare renal function of living ki...
