Total organic carbon, organic phosphorus, and biogenic barium fluxes as proxies for paleomarine productivity
Shane D. Schoepfer,Jun Shen,Jun Shen,Hengye Wei,R. V. Tyson,Ellery D. Ingall,Thomas J. Algeo,Thomas J. Algeo +7 more
TL;DR: In this paper, the accumulation rates of three commonly used proxies for productivity from a set of primarily Quaternary sediment cores at 94 marine sites, compiled from 37 published sources, were evaluated for total organic carbon, organic phosphorus, and biogenic barium (Babio).

A Special Material or a New State of Matter: A Review and Reconsideration of the Aerogel
TL;DR: In this review, the characteristics, classification, history and preparation of the aerogel were introduced and more attention was paid to the sol-gel method for preparing different kinds of aerogels, given its important role on bridging the synthetic parameters with the properties.
Recent Advances in Friction Stir Welding/Processing of Aluminum Alloys: Microstructural Evolution and Mechanical Properties
TL;DR: Friction stir welding (FSW) has been termed as green technology due to its energy efficiency and environment friendliness as mentioned in this paper, which is an enabling technology for joining metallic materials, in particular lightweight high-strength aluminum and magnesium alloys.

Marine productivity changes during the end-Permian crisis and Early Triassic recovery
Jun Shen,Jun Shen,Shane D. Schoepfer,Qinglai Feng,Lian Zhou,Jianxin Yu,Huyue Song,Huyue Song,Hengye Wei,Thomas J. Algeo,Thomas J. Algeo +10 more
TL;DR: In this article, the authors assess secular and regional patterns of productivity variation during the end-Permian mass extinction through an analysis of the burial fluxes of three elemental proxies: total organic carbon (TOC), phosphorus (P), and biogenic barium (Babio), showing that primary productivity rates appear to have increased from the pre-crisis Late Permian through the Early Triassic in many parts of the world.

Nanocellulose-derived highly porous carbon aerogels for supercapacitors
TL;DR: In this article, high-surface-area carbon aerogels are synthesized by pyrolysis of nanocellulose aerogel that are prepared by dissolving of cellulose microcrystalline in NaOH aqueous solutions followed by gelation, regeneration and freeze drying or supercritical CO2 drying.
