Structural modification of A-C-A configured X-PCIC acceptor molecule for efficient photovoltaic properties with low energy loss in organic solar cells.

Modification of terminal acceptors of non-fullerene organic solar cell molecule with different terminal acceptors can help in screening of molecules to develop organic photovoltaic cells with improved performance. Thus, in this work, seven new molecules with an unfused core have been designed and thoroughly investigated. DFT/TD-DFT simulations were performed on studied molecules to explore the ground and excited state characteristics.

Enhancing the photoinduced via a novel nano-combination of terbium oxide and nickel oxide on graphene oxide surface: Cytotoxicity and water treatment.

The target is a novel nano-combination membrane (NCM) via Terbium oxide nanoparticles (TbO NPs) and nickel oxide (NiO NPs) which integrates on the graphene oxide (GO) surface. The NCM is characterized by different tools such as X-ray diffraction (XRD), UV-visible spectrophotometer (UV-vis), and Scanning electron microscopy (SEM)for removing organic pollutants. The precipitation method has been applied for fabricating the selected metal oxides (MOs), where the terbium chloride and nickel chloride are used as precursors for fabricating the metal oxides (MOs) NPs that formed with potassium hydroxide in the solution.

Selective adsorption of antiphospholipid and anti-dsDNA autoantibodies on histidine based pseudobioaffinity adsorbent from sera of patients with systemic lupus erythematosus (SLE).

Systemic lupus erythematosus (SLE) is an autoimmune diseases characterized by the presence of antiphospholipid and anti-dsDNA autoantibodies in the sera of patients. These autoantibodies and their subclasses have received increasing attention by medical community due to their association with recurrent venous thrombosis, fetal loss and thrombocytopenia. In particular, attention has been paid to IgG subclasses in SLE.

Effect of endogenous and synthetic antioxidants on hydrogen peroxide-induced guinea-pig colon contraction.

Objectives And Design: The effects of the endogenous antioxidant alpha-lipoic acid on guinea pig colon smooth muscle contraction (Gpcc) induced by hydrogen peroxide were examined. Having previously shown that the histone deacetylase (HDAC) benzamide inhibitor MGCD0103 inhibits guinea-pig smooth muscle contraction, as do various sulfur-containing antioxidants, we asked whether hybrid compounds possessing both alpha-lipoic acid-derived antioxidant properties and HDAC inhibitory activity could inhibit Gpcc.

Materials And Methods: Guinea pig colon (Gpc) was incubated at 37 degrees C with Krebs buffer; the four stimulants-hydrogen peroxide, carbachol, histamine, and sodium fluoride-were added independently.

Effect of antioxidants on airway smooth muscle contraction: action of lipoic acid and some of its novel derivatives on guinea pig tracheal smooth muscle.

Objectives And Design: The aim of this study was to investigate the ability of (a) antioxidants, some related to alpha-lipoic acid (LA), (b) histone deacetylase (HDAC) inhibitors, and (c) hybrid compounds possessing both alpha-lipoic acid-derived antioxidant properties and HDAC inhibitory activity to inhibit guinea pig smooth muscle contraction.

Materials And Methods: Guinea pig isolated tracheal rings (GPTR) were prepared and their isometric tension measured using a transducer. Histamine, carbachol and 5-hydroxytryptamine (5-HT) served as agonists.
