Modeling lignin polymerization, I: simulation model of dehydrogenation polymers [PDF]

open access: yes, 2010
Lignin is a heteropolymer that is thought to form in the cell wall by combinatorial radical coupling of monolignols. Here, we present a simulation model of in vitro lignin polymerization, based on the combinatorial coupling theory, which allows us to ...

Hierarchical Cellulose/MXene Aerogel Films with Coral‐Like Polyaniline Skin for Absorption‐Led Broadband EMI Shielding

open access: yesAdvanced Functional Materials, EarlyView.
A regenerated cellulose/MXene aerogel film is engineered with a surface‐confined, coral‐like polyaniline skin to intensify interfacial polarization while a porous, percolated conductive core is retained. By molten salt hydrate processing and interfacially confined oxidative polymerization, PANI growth is localized at the outer surface and internal ...

A Study of the Feasibility of Using a Pulping Aid with Polysulfide Kraft Cooks [PDF]

open access: yes, 1970
The purpose of this paper was to determine the feasibility of using a pulping aid with a polysulfide kraft cook. Since any change in an operation such as pulping must yield a product such that the quality is better or not appreciably reduced and at the ...

Nano‐Engineered Titanium Implants Loaded With Gingival Fibroblasts‐Derived Microvesicles Enhance Early Osseointegration And Soft Tissue Attachment In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Our study showed that human primary gingival fibroblast–derived microvesicles on nano‐engineered titanium implants promote early osseointegration and soft‐tissue attachment in vivo. ABSTRACT Titanium dental implants require both reliable osseointegration and peri‐implant soft tissue seal formation to ensure long‐term success. While osseointegration has

Properties of high quality paper from rag fibers recycling [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2012
In this investigation, soda pulps from old rags applying three pulping times (60, 120 and 180 minutes ) and three levels of active alkali ( 6,8, and 10% NaOH based on OD weight  of rag) and pulping temperature of 125º C were produced. Liquor to rag ratio

A Mechanistic Study of Bio‐Based Nanotemplated Carbon Nanofibers Derived From Water Processable Lignin Blends for Sustainable Energy Storage Applications

open access: yesAdvanced Materials, EarlyView.
As‐spun carbon materials produced from Lignosulfonate, gelatin, and alginate, selected for water solubility, and ability to produce templated sustainable carbon nanostructures. Gelatin and alginate are sacrificial during thermal processing, allowing the production of engineered high surface area nanostructures, which are further characterized for ...
