Norjizak is a new drug abused in the past few years in Iran with symptoms and complications distinct from other common forms of drug and characterized by higher rate of mortality. The present study aims to analyze the chemical components of this substance. Five samples were obtained from abusers referring from different areas of Tehran to a treatment clinic. All samples were 2 ml vials with yellowish fluid. Thin Layer Chromatography (TLC) was performed first to analyze the samples semi-quantitatively and the quantitative levels of components were then explored using high-performance liquid chromatography (HPLC). TLC revealed steroid (in form of betamethasone), heroin, codeine, morphine and thebaine in all five samples. Four samples contained acetaminophen and two samples contained caffeine. None of them contained amphetamine, benzodiazepine, tricyclic antidepressant, aspirin, barbiturates, tramadol and buprenorphine. HPLC revealed that heroin, codeine, morphine and thebaine constituted the narcotic foundation in all samples. In addition, the heroin to acetylcodeine ratio was significantly lower in three samples, which indicates their higher toxicity. The results of the present study on the chemical components of Norjizak showed that this substance is an opiate one similar to heroin and the heroin-based crack prevalent in Iran which contains betamethasone.

Enhancing oil recovery in sandstone reservoirs, particularly through smart water flooding, is an appealing area of research that has been thoroughly documented. However, few studies have examined the formation of water-in-heavy oil emulsion because of the incompatibility between the injected water-folded ions, clay particles, and heavy fraction in the oil phase. In this study, we investigated the synergistic roles of asphaltene and clay in the smart water flooding process using a novel experimental approach.

In order to evaluate the stability of an amorphous solid dispersion (ASD) it is crucial to be able to accurately determine whether the ASD components are homogeneously mixed or not. Several solid-state analysis techniques are at the disposal of the formulation scientist, such as for example modulated differential scanning calorimetry (mDSC) and solid-state nuclear magnetic resonance spectroscopy (ssNMR). ssNMR is a robust, versatile, and accurate analysis technique with a large number of application possibilities.

Developing of molecular crystalline materials with light-induced multiple dynamic deformation in space dimension and photochromism on time scales has attracted much attention for its potential applications in actuators, sensoring and information storage. Nevertheless, organic crystals capable of both photoinduced dynamic effects and static color change are rare, particularly for multi-component cocrystals system. In this study, we first report the construction of charge transfer co-crystals allows their light-induced solid-to-liquid transition and photochromic behaviors to be controlled by trans-stilbene (TSB) as an electron donor and 3,4,5,6-Tetrafluorophthalonitrile (TFP) as an electron acceptor.

The jute hairy caterpillar, Spilosoma obliqua (Lepidoptera: Erebidae) is considered as one of the major threats to jute cultivation. The best eco-friendly methods to combat these jute pests involve administration of nano-biopesticides, as a successful alternative to the toxic chemicals. In this study, a nano-biopesticide formulation containing green synthesized silver nanoparticles (Ag NPs) using Ocimum sanctum leaf extract has been proposed.
