Friction stir welding of SS 316 LN and Nitronic 50 jacket sections for application in superconducting fusion magnet systems (open access)

Friction stir welding of SS 316 LN and Nitronic 50 jacket sections for application in superconducting fusion magnet systems

Article explores the possibility of using friction stir welding (FSW) to join jacket web sections of two nitrogen-containing stainless steels for housing internally cooled superconducting cables which are utilized to generate magnetic fields in tokamak type fusion reactor systems. It has been shown that the FSW fabricated SS 316 LN jackets possessed the required strength and magnetic properties critical to this application.

Finding new friends and revisiting old ones – how plant lipid droplets connect with other subcellular structures (open access)

Finding new friends and revisiting old ones – how plant lipid droplets connect with other subcellular structures

Article talks about how the number of described contact sites between different subcellular compartments and structures in eukaryotic cells has increased dramatically in recent years, which has substantially reinforced the well-known premise that these kinds of connections are essential for overall cellular organization. The authors discuss contact sites involving plant lipid droplets (LDs), including LD-endoplasmic reticulum (ER) connections that mediate the biogenesis of new LDs at the ER, LD-peroxisome connections.

Regulating C2H2/CO2 adsorption selectivity by electronic-state manipulation of iron in metal-organic frameworks (open access)

Regulating C2H2/CO2 adsorption selectivity by electronic-state manipulation of iron in metal-organic frameworks

Article reports a metal electronic-state manipulation strategy to construct a pair of isostructural and interconvertible Fe-MOFs featuring open Fe centers with different electron densities for efficient Câ‚‚Hâ‚‚/COâ‚‚ separation. The authors show that the presence of Fe[II] centers with a medium-spin-state trail plays a crucial role in the enhanced Câ‚‚Hâ‚‚ selective adsorption.

Biochar aerogel-based electrocatalyst towards efficient oxygen evolution in acidic media (open access)

Biochar aerogel-based electrocatalyst towards efficient oxygen evolution in acidic media

Article argues that traditional acidic oxygen evolution reaction (OER) electrocatalysts are more prone to be oxidized and corroded as results of unstable carrier structures and variable electronic states of active species, so a high-performing biochar aerogel (BA) based electrocatalyst was realistically designed and synthetized via joint utilization of the terrestrial lignin and seaweed polysaccharide as carbon sources. This work puts forward a novel and effective strategy towards the enhancement of the acidic OER process by rational regulations of the BA and the coupling effect in micro-interface.

Complexity synchronization: a measure of interaction between the brain, heart and lungs

Authors of the article address the measurable consequences of the network effect (NE) on time series generated by different parts of the brain, heart, and lung organ-networks (ONs), which are directly related to their inter-network and intra-network interactions. The authors assert that these same physiologic ONs have been shown to generate crucial event (CE) time series, and herein are shown ,using modified diffusion entropy analysis (MDEA) to have scaling indices with quasiperiodic changes in complexity, as measured by scaling indices, over time.

Manipulating microRNA miR408 enhances both biomass yield and saccharification efficiency in poplar

Article describes how the conversion of lignocellulosic feedstocks to fermentable sugar for biofuel production is inefficient, and most strategies to enhance efficiency directly target lignin biosynthesis, with associated negative growth impacts. The authors demonstrate, for both laboratory-and field-grown plants, that expression of Pag-miR408 in poplar significantly enhances saccharification, with no requirement for acid-pretreatment, while promoting plant growth.
