Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

The Relationship Between Maximal Strength and Reactive Strength

International Journal of Sports Physiology and Performance, 2017
Maximum- and reactive-strength qualities both have important roles in athletic movements and sporting performance. Very little research has investigated the relationship between maximum strength and reactive strength. The aim of this study was to investigate the relationship between maximum-strength (isometric midthigh-pull peak force [IMTP PF]) and ...

Laboratory Investigation on Reactivated Residual Strength

Journal of Geotechnical and Geoenvironmental Engineering, 2008
Recent research has outlined that mobilized in situ strength at the reactivation of displacements along a preexisting sliding surface may be slightly greater than laboratory residual strength. Although geotechnical literature explains this difference in various ways — for instance, strength gain due to soil aging — little work has been devoted to this ...

Enhancing the reactivity and strength of cotton fibers

Journal of Applied Polymer Science, 1992
AbstractBoth sodium hydroxide solution of mercerizing strength and anhydrous methylamine are suitable pretreatments for enhancing the reactivity of cotton cellulose. Favorable results are achieved by maintaining the fiber material in the never‐dried state after the swelling treatment. Extraction by organic solvents is to be preferred over water‐washing

Flexural Strength of the Reactive Powder Concrete

Solid State Phenomena, 2016
Reactive powder concrete (RPC) is cement composite which is characterized by an absence of coarse aggregate. That resulted in a greater homogeneity of the mixture and thus also in a higher compressive strength. On the other side, the absence of coarse aggregate and typically a large volume of the paste lead to the deterioration of some of the ...

Zinc Ammonio-dodecaborates: Synthesis, Lewis Acid Strength, and Reactivity

Inorganic Chemistry, 2022
Two series of zinc salts, [EtZn][A] and Zn[A]2, with weakly coordinating anions [A]- as counterions have been prepared, and their activities as catalysts for hydrosilylation reactions of 1-hexene, benzophenone, and acetophenone have been investigated. The counterions and per- and partially chlorinated 1-ammonio-closo-dodecaborate anions [Me3NB12Cl11]- [

Strength and Ductility of Reactive Powder Concrete Columns

Key Engineering Materials, 2009
Two hollow rectangular bridge columns with Reactive powder concrete (RPC) were tested under a cyclically reversed horizontal load. Based on the test results, the seismic behavior of such columns was presented. An analytical model was developed to predict the force-displacement relationship of specimens.

Strength and Stiffness of Aluminum/PTFE Reactive Composites

Recent Advances in Solids and Structures, 2001
Abstract Aluminum/Polytetrafluoroethylene mixtures are currently being studied as reactive material compositions, with focus on shock or impact ignition. In addition, there is an emphasis on increasing the strength of these composites to survive high strain-rate deformation.

Effect of pore structure and matrix reactivity on coke reactivity and post-reaction strength

Metallurgical Research & Technology, 2017
Metallurgical coke accounts for a significant portion of the costs associated with blast furnace operations. The coke reactivity index (CRI) and coke strength after reaction (CSR), determined via the Nippon Steel Corporation test, are the most popular indexes for estimating the high-temperature properties of coke.
