Lead-free halide perovskite memristors for scalable crossbar arrays

open access: yesNano Convergence
Lead-free halide-perovskite memristors have advanced rapidly from initial proof-of-concept junctions to centimeter-scale selector-free crossbar arrays, maintaining full compatibility with CMOS backend processes.

Stress Tensor of the Hydrogen Molecular Ion [PDF]

open access: yes, 2009
The electronic stress tensor of the hydrogen molecule ion H_2^+ is investigated for the ground state (sigma_g 1s) and the first excited state (sigma_u^* 1s) using their exact wave functions.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Tris(4-hydroxypyridinium) hydrogen sulfate–sulfate monohydrate

open access: yesActa Crystallographica Section E, 2009
In the crystal structure of the title salt, 3C5H6NO+·HSO4−·SO42−·H2O, the hydrogen sulfate ion is linked to the sulfate ion by an O—H...O hydrogen bond. The hydrogen sulfate–sulfate anion

Stellar wind bubbles around WR and [WR] stars [PDF]

open access: yes, 2002
We study the dynamics of stellar wind bubbles around hydrogen-deficient stars using numerical simulations with time- and ion dependent cooling. We consider two types of hydrogen-deficient stars, massive WR stars, producing Ring Nebulae, and low mass [WR]

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

OXIDATION OF AQUEOUS SOLUTION OF BROMIDE USING H2O2 , UV AND PEROXONE [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2012
In this study , aqueous solutions of bromine were prepared with different concentration ranging from (0.025, 0.030, 0.035, 0.040, 0.045 to 0.050 N ) . At the beginning the oxidation was done using only Hydrogen peroxide then only ultraviolet radiation at

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Crystal structure of bis[μ-bis(diphenylphosphanyl)methane-κ2P:P′]-μ-chlorido-chlorido-1κCl-(1-phenylthiourea-2κS)disilver acetonitrile hemisolvate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each AgI ion displays a distorted tetrahedral coordination geometry with two P atoms from two bis(diphenylphosphanyl)methane (dppm) ligands, one bridging chloride ion, one terminal ...
