Coal Fly Ash Decorated with Graphene Oxide–Tungsten

Coal fly ash was decorated with a graphene oxide–tungsten oxide nanorods nanocomposite (CFA/GO/WO 3 NRs nanocomposite) via a hydrothermal method and applied for the remediation of lead (Pb 2+ ions). The Pb 2+ ion-loaded spent adsorbent (CFA/GO/WO 3 NRs + Pb 2+ nanocomposite) was reused for the photodegradation of acetaminophen.

Fuel Cell explained

1 – Origins and principle 1. Back to the origins: from the gas battery to the fuel cell The seminal work of William Grove on fuel cells in 1839 is well known nowadays but at the time of his invention, the scientist rather called the device a "gas voltaic battery". Therefore

Separator technologies for lithium

2010/12/30US patents 4994335, 4138459, 3801404, and 3843761 have described this process in detail. Generally speaking, a uniaxially stretched membrane exhibits good mechanical properties (150-MPa tensile strength) but a high thermal shrinkage in the machine direction, while a low tensile strength (15 MPa) but a negligible thermal shrinkage in the transverse direction.

Nanocomposites: synthesis, structure, properties and new

Similarly, patents with complete document on nanocomposites account for about 4663 during the same period as per Scirus ). Additionally, specific conferences and special issues of some journals have been devoted exclusively to the emerging science and technology of nanomaterials.

Recent Advances in Heterogeneous Photocatalytic

During the process and operation of the dyes, the wastes produced were commonly found to contain organic and inorganic impurities leading to risks in the ecosystem and biodiversity with the resultant impact on the environment. Improper effluent disposal in aqueous ecosystems leads to reduction of sunlight penetration which in turn diminishes photosynthetic activity, resulting in acute toxic

Cloth Face Masks Containing Silver: Evaluating the Status

2021/4/16This has led to both new and existing companies to manufacture reusable cloth face masks, some of which are impregnated or coated with nanoparticles including silver, copper, graphene, and zinc. (3,4) The market of antiviral coatings is currently valued at $0.5 billion US dollars and is expected to grow to $1.3 billion by 2027, with silver coatings predicted to be the most profitable.

Bicarbonate or Carbonate Processes for Coupling Carbon

More than 60% of these patents were published since the year 2000, and a sharp increase in patent nos. was seen in the last several years: ∼25% patents were published in the last 2 years. Substantially more patents on CO2 removal and sepn. technologies are expected in the coming years.

Fuel cell

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes

Advantages and Limitations of Microwave Reactors: From

Further patents include liquefaction of biomass, whether it is a pyrolysis to prepare oil specifically rich in aromatics(228,229,233) or furfural, a reactive dissolution using ionic liquids, which are themselves a good microwave absorbents, or even torrefaction to (9).

GT

Three grades of impregnated graphite, using two different resin types to cover steel industry applications. We are the second company in the world able to supply "real" PTFE impregnated graphite. Our GT-FLON show extraordinary corrosion properties outclassing traditional phenolic resin impregnated graphite.

US5501729A

A pitch based impregnant for a carbon or graphite body and a method of impregnation. The method involves forming a liquid solution of a substantially solids free pitch having a Q.I. of less than 1% dissolved in furfural and containing an acid catalyst with the solution having a viscosity of less than 150 cps at room temperature and heating the impregnated body to between 150-200 C. until

Frontiers

Biogas is defined as the mixture of CH4 and CO2 produced by the anaerobic digestion of biomass. This particular mixture can be transformed in high valuable intermediates such as syngas through a process known as dry reforming (DRM). The reaction involved is highly endothermic, and catalysts capable to endure carbon deposition and metal particle sintering are required. Ni-pyrochlore catalysts

Who made the first fiberglass fly rod

His only patents up until then were for tires and artificial limbs. His only patent for fishing rods came later for his "sandwich" method of compressing the impregnated cloth to the mandrel. This was quickly abandoned because it resulted in two spines that had to be carefully ground off and the guides had to be carefully oriented on the shaft.

Carbon Nanotubes: A Review on Structure and Their

Carbon nanotubes (CNTs) are allotropes of carbon with a nanostructure that can have a length-to-diameter ratio greater than 1,000,000. Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, and chemical vapor deposition. Developments in the past few years have illustrated the potentially revolutionizing impact of nanomaterials
