Colloidal syntheses of PbSe nanocrystals (NCs) have been widely investigated and the properties of nanocrystals have been shown to vary with reaction conditions, time, concentration and chemistry of reagents as well as the surfactants used. In this work the effects of reaction temperature, solvents, ligand purity, lead and selenium sources on the optical and structural properties of PbSe nanocrystals were investigated. PbSe NCs synthesized at 90 °C were observed to be spherical and had a narrower size distribution as compared to those synthesized at higher temperatures. 1-octadecene, trioctylphosphine and oleylamine were investigated as solvents for NC synthesis with the non-coordinating solvent octadecene showing the fastest growth rate with medium sized NCs. The coordinating solvents trioctylphosphine and oleylamine produced larger and smaller NCs respectively; this could be attributed to solvent interference during NC nucleation and growth phases. Oleate ligands were used during these syntheses and the ligand purity was not observed to have a significant effect on the NC optical and structural properties. The selenium precursor used affected the NC size and their optical properties while the lead source influenced both the NC shape and size. Lead acetate produced cubic NCs which were larger than the spherical NCs obtained when lead oxide was used.

Lead acetate (lead ac.) is a widespread ecological toxicant that can cause marked neurotoxicity and decline in brain functions. This study aimed to evaluate the possible neuroprotective role of L-ascorbic (ASCR) and curcumin (CRCM) alone or together against lead ac.-induced neurotoxicity. Rats were injected with lead ac. then treated orally with ASCR and CRCM alone or in combination for seven days. Lead ac. caused elevation in brain tumor necrosis factor- α (TNF-α), interleukin-6 (IL-6), caspase-3, and malondialdehyde (MDA) levels, while superoxide dismutase (SOD), reduced glutathione (GSH) as well as the expression of brain-derived neurotrophic factor (BDNF), cAMP response element-binding (CREB) and Beclin1 were down-regulated. Expressions of C/EBP homologous protein (CHOP) and mammalian Target of rapamycin kinase (mTOR) were upregulated in brain tissues matched with the control group. Histopathological examination supported the previously mentioned parameters, the administration of the antioxidants in question modulated all the altered previous parameters. The combination regimen achieved the superlative results in the antagonizing lead ac.-induced neurotoxicity via its antioxidant and anti-apoptotic activities.

AbstractModified sol-gel processes have been developed for the preparation of precursor solutions of undoped, La and Ta doped PZT (25/75). These processes use different solvents (methoxyethanol, butoxyethanol) and different lead sources (lead acetate, lead oxide). Due to variations in the structure and in the composition of the solutions, significantly different thermal decomposition behaviors were found. These inevitably affected texture and microstructure of the sol-gel derived thin films, demonstrating the important role of precursor chemistry in the improvement of film properties. In the case of tantalum doped Pt/PZT/Pt ferroelectric capacitors a rectangular hysteresis loop, featuring high Pr, was obtained for one specific precursor chemistry.

ABSTRACTWe report a robust method by which colloidal PbS nanosheets can be synthesized with nearly 100% success rate. It is achieved by replacing the lead acetate by lead oxide for preparation of the lead precursor. Acetic acid either injected externally or produced during the reaction can significantly affect the growth of the nanosheets. The existence of water in the reaction solution makes the nanosheets smaller in lateral size while the purity of trioctylphosphine has no significant effect on the nanosheet growth.

Hylocereus Polyrhizus

Lead is a heavy metal, the main polluting material in the environment, which comes from gasoline, batteries, paint, pipes, soil, cosmetics, household appliances, and decorations. Lead is a free radical causing oxidative stress. Lead can accumulate in the body due to its slow elimination process. Lead increases oxidative stress by forming reactive oxygen species (ROS) such as superoxide ion (O2-), hydroxil radical (OH-), and nitric oxide (NO), and direct suppression of antioxidant reserves such as Superoxide Dismutase (SOD), Catalase, and Glutathione Peroxide (GPx). Hylocereus polyrhizus peel is a natural antioxidant that can overcome the toxic effects of lead. The aim of this study was to analyze the treatment of Hylocereus polyrhizus peel extract orally once in a day for 40 days to increase testosteron levels of Balb/C mice (Mus musculus) exposed to lead acetate. The type of this study was true experimental study with Post Test Only Control Group design. Forty mice aged 8-10 weeks and the range of the body weight 30-40 grams were divided into 5 groups (each group of 8 mice). K- group was the control group without lead acetate and Hylocereus polyrhizus peel extract. K+, P1, P2 and P3 group was given 100 mg/kgBW lead acetate orally on the 1st day until day 14th. P1, P2 and P3 group was continued by giving Hylocereus polyrhizus peel extract orally on the 15th day until 39th day. P1 with dose 250 mg/KgBW, P2 with dose 500 mg/KgBW, and P3 with dose 1000 mg/KgBW. The results showed significant differences in testosterone levels between the K+ groups with P1 and P2. The conclusion of this study is Hylocereus polyrhizus peel extract can increase the testosteron levels of mice exposed to acetate lead.
