The proton conduction mechanism in protic ionic liquids

Credit: Niigata University Niigata, Japan - Researchers from the Graduate School of Science and Technology at Niigata University, Japan along with their collaborators from Tokyo University of Science (Japan), Yamagata University (Japan) and University of Regensburg (Germany) have published a scientific article which enhances clarity on the understanding of proton conduction mechanism in protic ionic liquids. The findings which were recently published in The Journal of Physical Chemistry B sheds light on the transport of hydrogen ions in these liquids, which opens new avenues for the development of novel energy generation and storage devices. With an objective to understand the underlying ion transport mechanism in protic and pseudo-protic ionic liquids, the multinational research team has been on constant pursuit for over a decade to uncover the mystery. We are fascinated by the immense potential exhibited by proton conducting ionic liquids. These superionic liquids are usually

Tungsten-substituted vanadium oxide breathes fresh air into catalyst technology

Their new catalyst material works at lower temperatures and does not suffer major drops in performance when processing wet exhaust, resolving a major drawback in conventional vanadium oxide catalysts. They found that the unaggregated dispersal of atomic tungsten in the original crystal structure plays a key role in how it functions.

Recovery of ovarian function in infertile mammals lacking gonadotropin release

 E-Mail IMAGE: This study has found that KNDy neurons are key to controlling ovarian function in mammals. These neurons express signalling molecules (peptides) in the brain that stimulate pulses of a hormone. view more  Credit: Sho Nakamura Gonadotropins are any hormones that are released from the anterior pituitary to stimulate the gonads, or sex glands, to carry out their reproductive functions. The gonadotropin-releasing hormone (GnRH) is therefore fundamental for mammalian reproduction. In a healthy reproductive system GnRH is produced by the brain in pulses. Reports suggest that at least 25% of ovarian disorders are due to dysfunction of the brain mechanism controlling the release of gonadotropins, which is a kind of reproductive disorder associated with the hypothalamus.

Boosted photocatalysis for hydrogen evolution: Reactant supply thru phosphonate groups

However, processes inside the solution had yet to be thoroughly explored. One recent approach to improve photocatalytic hydrogen production was proposed by loading phosphonate groups on the surface of the visible-light-responsive photocatalyst lanthanum and rhodium-doped strontium titanate (La,Rh:STO) with a silane coupling agent. The phosphonate functional group functions as a mediator of proton supply (i.e., promotes the supply of reactants) and improves hydrogen production activity.
