Catalytic reduction of toxic dyes over nickel oxide nanoparticles supported on CMK-3 catalyst.

In the current paper, a NiO nanoparticles-loaded mesoporous carbon (CMK-3) catalyst, denoted as NiO/CMK-3, has been successfully synthesized using a facile strategy. The as-prepared material has been characterized through XRD, Raman spectroscopy, low-temperature N physisorption measurements, FTIR, FE-SEM, TEM, and XPS. The as-fabricated NiO/CMK-3 catalyst manifested a superior activity in the NaBH-assisted reduction of methylene blue (MB) dye to its colorless leuco form.

Pushing the limits of PLA by exploring the power of MWCNTs in enhancing thermal, mechanical properties, and weathering resistance.

The present study focuses on enhancing the mechanical, thermal, and degradation behavior of polylactic acid (PLA) by adding carbon nanotubes (CNTs) with different concentrations of 0.5, 1, 3, and 5%. The CNTs were prepared using catalytic chemical vapor deposition, and the prepared PLA/CNTs nanocomposite films were characterized using techniques such as FT-IR, Raman spectroscopy, TGA, SEM, and XRD.

Facile Synthesis of ZnS/1T-2H MoSnanocomposite for Boosted adsorption/photocatalytic degradation of methylene blue under visiblelight.

Facile solvothermal techniques were used to manufacture ZnS/1T-2H MoS nanocomposite (ZMS) with outstanding adsorption-photocatalytic activity. The formed catalyst was characterized by different tools; XRD, HR-TEM, EDX, FTIR, Raman, Nadsorprion/desorption, Zeta potential, PL,and XPS. The analysis provided the formation on mixed phase of metallic 1Tand 2H phases.

In vitro neurogenesis from neural progenitor cells isolated from the hippocampus region of the brain of adult rats exposed to ethanol during early development through their alcohol-drinking mothers.

Aims: This study was aimed to determine whether ethanol exposure during early development altered neurogenesis in the brain of adult rats.

Methods: Pregnant rats were given either ethanol-mixed or mannose-mixed (for control) rodent liquid diet ad libitum. Ethanol drinking continued during pregnancy and nursing.

Incremental cost-effectiveness of supplementary immunization activities to prevent neonatal tetanus in Pakistan.

Objective: This study aimed to estimate the incremental cost-effectiveness of supplementary immunization activities to prevent neonatal tetanus in the Loralai district of Pakistan. The supplemental immunization activities were carried out in two phases during 2001-03.

Methods: A state-transition model was used to estimate the effect of routine vaccination with tetanus toxoid as well as vaccination with tetanus toxoid during supplementary immunization activities.

Insomnia in children: when are hypnotics indicated?

Insomnia in children is a nonspecific impairing symptom that may be the result of normal developmental changes, psychosocial duress, a sleep disorder, a psychiatric disorder, other medical disorders, substance misuse, or an adverse effect of medication. Careful clinical assessment of insomnia in children may include the use of symptom rating scales, laboratory testing, or other medical assessment. Short- and long-term treatment of insomnia in children involves management of etiological factors and associated syndromes.
