Si-based anodes in lithium ion batteries (LIBs) have exceptionally high theoretical capacity, but the use of a Si-based anode in LIBs is problematic because the charging-discharging process can fracture the Si particles. Alginate and its derivatives show promise as Si particle binders in the anode. We show that calcium-mediated "egg-box" electrostatic cross-linking of alginate improves toughnes...

in this paper, the effect on the strength properties of high strength concrete (hsc) manufactured with silica fume (sf) and ground pumice (gp) is investigated. portland cement was replaced with sf, gp and combination of sf and gp up to 25%. 22 different concrete mixtures with these replacement ratios were produced by using 0.25 water-binder ratio. the ultrasound pulse velocity, compressive, spl...

binders are of prime importance in the agglomeration of iron ore concentrates. in this research, strength and density of briquette produced from the magnetite concentrate of gol-e-gohar were investigated using different binders at various applied pressures. the results showed that peridor was the most effective binder relative to bentonite and lime. for all types of binders, the increase in bin...

Hand-held signals (HHS) are used in signaling troop movements and aircraft. Meant to attract attention and to identify the positions of military personnel, HHS technologies find use in both training exercises and combat situations, and improvements are being sought to advance existing HHS technology. One of the most popular HHS items used by the US military for illuminating purposes is the M127...

Abstract Magnesium silicate hydrate (M–S–H) formed on reaction of MgO and reactive SiO 2 imparts binding characteristics similar to Portland cement (PC). Limited knowledge is available the long-term mechanical durability performance M–S–H binder systems. In this study, MgO–SiO was assessed up 365 days. addition silica fume (SF), most widely used source with MgO, calcined clay (CC) kaolinite con...

The objective of this study is to evaluate the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica. In this study, the nanosilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binders. Superpave binder and mixture tests were utilized in this study to estimate the characteristics of the nano-modifed aspha...

The use of an oral phosphate binder is a promising and most practical strategy for the prevention of vascular calcification in patients with chronic kidney disease (CKD). To secure the safety: 1) the oral phosphate binder must not cause adverse effects in the gastrointestinal tract; 2) the oral phosphate binder should be non-absorbable or barely absorbable through the gastrointestinal tract, or...

Abstract In this paper, S95 grade ultrafine mineral admixture (UMA) was prepared by water quenched manganese slag and fly ash 1:1 compound mechanical ball milling to a specific surface area of 714 m2/kg. Its activity index 86.8% at 7d 96.3% 28d. The UMA has the characteristics small particle size, high activity. Mixing with powders different sizes, such as cement silica fume (SF), is helpful im...

Recently, nanomaterials have been widely used to improve the properties of asphalt binders due their unique properties. This research aims evaluate performance nano-modified with two different types nanomaterials, which are Nano-Silica (NS) and Nano-Clay (NC). Each them was added a 60/70 penetration grade bitumen at concentrations ranging from 1% 4% by binder weight using high shear mixer speed...

This work explored the formation of mesoporous silicas pellets using a range bentonite and colloidal silica (LUDOX) fractions, aiming to optimise binder composition that minimises any deteriorating effects on adsorption performance, while providing adequate mechanical integrity. Thermogravimetric analysis, scanning electron microscopy, dynamic analysis were used structurally characterise pellet...
