A series of new coordination complexes of La(III) and Pr(III) with hydrazones, derived from 1,1-diacetylferrocene and different aromatic acid hydrazides have been synthesized and characterized by elemental analyses, electrical conductance, magnetic moment, IR, (1)H NMR, UV-vis spectra and molar conductance. The thermal behaviour of the complexes under non-isothermal condition was investigated by TG and DTG techniques. The antifungal activity of hydrazones and their corresponding complexes were also investigated.

The concise synthesis of O-methyled-inositol derivative and conduritol derivatives was obtained starting from p-benzoquinone. Spectroscopic methods have been performed for characterization of new synthesized compounds. Cyclitols are useful molecules with anticancer, antibiotic, antinutrient and antileukemic activity.

Background: Tissue engineering for bone regeneration aims to heal severe bone injuries. This study aimed to prepare and assess the early osteogenic differentiation effects of a gelatin/calcium phosphate- Punica granatum nanocomposite scaffold on stem cells from human exfoliated deciduous (SHED) and human dental pulp stem cells (HDPSCs).
Methods: The electrospinning method was used to prepare a gelatin/calcium phosphate nanocomposite scaffold containing pomegranate (Punica granatum) extract.

Organic redox systems that can undergo oxidative and reductive (ambipolar) electron transfer are elusive yet attractive for applications across synthetic chemistry and energy science. Specifically, the use of ambipolar redox systems in proton-coupled electron transfer (PCET) reactions is largely unexplored but could enable "switchable" reactivity wherein the uptake and release of hydrogen atoms are controlled using a redox stimulus. Here, we describe the synthesis and characterization of an ambipolar functionalized terthiophene (TTH) bearing methyl thioether and phosphine oxide groups that exhibits switchable PCET reactivity.

Objective: Disorders of arousal (DoA) are characterized by an intermediate state between wakefulness and deep sleep, leading to incomplete awakenings from NREM sleep. Multimodal studies have shown subtle neurophysiologic alterations even during wakefulness in DoA. The aim of this study was to explore the brain functional connectivity in DoA and the metabolic profile of the anterior and posterior cingulate cortex, given its pivotal role in cognitive and emotional processing.

In this study, dye/polymer matrix-stabilized β-FeOOH nanomaterials were fabricated for therapeutic applications. Rh-B/F127@β-FeOOH nanomaterials were synthesized using two different methods: co-precipitation (CoP) and hydrothermal (HT) methods. The as-synthesized nanoparticles were characterized using various spectroscopic techniques, including FT-IR, UV-Vis, PL, XRD, HR-TEM, and XPS analysis.
