Published: January 2017

Formation of methanol and hydrocarbon derivatives from CO and H, their simplest molecular building blocks, under biocompatible conditions is proposed. Alternate panspermia of similar extraterrestrially formed and observed hydrocarbons to earth is also discussed. The simple molecular building blocks derived from CO and H are carbon sources in the initial stage of biological evolution of cells leading to life's origin.

Biosynthesis of silver nanoparticles from macroalgae Hormophysa triquetra and investigation of its antibacterial activity and mechanism against pathogenic bacteria.

Sci Rep

January 2025

Environmental Science Program, Department of Biological and Environmental Sciences, College of Arts and Sciences, Qatar University, P. O. Box: 2713, Doha, Qatar.

In this study, brown macroalgae Hormophysta triquetra (HT) collected from the Qatari coast is used to biosynthesize silver nanoparticles (AgNPs) from its aqueous (AQ), chloroform: methanol (MCF), and ethanolic extracts (ET). The NPs are characterized using Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Gas chromatography/Mass spectrometry (GC/MS) and X-ray photoelectron spectroscopy (XPS). The NPs were evaluated for their antibacterial activities by disc-diffusion method and their minimum inhibitory concentrations (MIC) were assessed.

Mechanistic Understanding of Dissociated Hydrogen in Cu/CeO-Catalyzed Methanol Synthesis.

ACS Appl Mater Interfaces

School of Physical Science and Technology, ShanghaiTech University, Shanghai 201210, People's Republic of China.

The hydrogen dissociation and spillover mechanism on oxide-supported Cu catalysts play a pivotal role in the hydrogenation of carbon dioxide to methanol. This study investigates the hydrogen spillover mechanism on Cu/CeO catalysts using spectral characterization under high-pressure reaction conditions and density functional theory (DFT) simulations. The research confirms that the Cu sites serve as the initial dissociation points for the hydrogen molecules.

Background: Anti-angiogenesis or inhibition of blood vessel formation is the best way to prevent the growth and metastasis of tumors. Natural sources like plants are currently being explored for its antiangiogenic activity as they are factories of various phytochemicals. The goal of the current study is to investigate the antiangiogenic potential of () by using chorioallantoic membrane (CAM) assay and molecular docking.

Several neurodegenerative diseases are associated with the deposition of amyloid fibrils. Although these diseases are irreversible, knowing the aggregation mechanism is useful in developing drugs that can arrest or decrease the aggregation rate. In this study, we are interested in investigating the effect of Coomassie brilliant blue (CBB G-250) on the aggregation of hen egg white lysozyme (HEWL) at pH 7.
