The balance between the market demand and natural abundance of rare-earth elements (REEs) in ores, often referred to as Balance Problem (or Balancing Problem), is a major issue for REE suppliers. ideal situation perfect match production REEs, so that there are no surpluses any REEs. This means industry must find new uses REEs available excess search substitutes have either limited availability or high demand. We present an overview trends applications different show use magnets, catalysts,...
This study assessed specific peaks obtained by diffuse reflectance Fourier transform mid‐infrared spectroscopy (DRIFTS) for characterizing the soil organic matter (SOM) composition of a Haplic Chernozem. Soils were collected from Static Fertilization Experiment, Bad Lauchstädt, Germany, during 5 years farmyard manure (FYM), mineral fertilizer (NPK), combination (FYM + NPK) and no (Control) treatments. extracted with hot water (HWE), fractionated size density. Bulk fractions analysed DRIFTS....
Abstract Microfluidic devices with three‐dimensional (3‐D) arrays of microelectrodes embedded in microchannels have been developed to study dielectrophoretic forces acting on synthetic micro‐ and nanoparticles. In particular, so‐called deflector structures were used separate particles according their size enable accumulation a fraction interest into small sample volume for further analysis. Particle velocity within the was measured by video microscopy hydrodynamic friction exerted deflected...
Organic reduced tillage aims to combine the environmental benefits of organic farming and conservation increase sustainability soil quality. In temperate climates, there is currently no knowledge about its impact on greenhouse gas emissions only little information carbon (SOC) stocks in these management systems. We therefore monitored nitrous oxide (N2O) methane (CH4) fluxes besides SOC for two years a grass-clover ley – winter wheat cover crop sequence. The monitoring was undertaken an...
Using agricultural wastes as an alternative phosphorus (P) source has great prospects to improve soil P status. A 70-day incubation experiment was carried out investigate the effects of superphosphate (SSP), poultry manure (PM), cattle (CM), maize straw (MS), and bone meal (CB) with same total input on availability fractions in typical acidic (red soil) alkaline (fluvo-aquic soils. The results showed that both fluvo-aquic red soils, CM out-performed other sources improving availability....
We demonstrate that micrometre and sub-micrometre particles can be trapped, aggregated concentrated in planar quadrupole electrode configurations by positive negative dielectrophoresis. For less than diameter, concentration is driven thermal gradients, hydrodynamic effects sedimentation forces. Liquid streaming induced the AC field itself via local heating results, under special conditions, vortices which improve trapping efficiency. Microstructures were fabricated electron-beam lithography...
A traveling-wave-driven electrohydrodynamic micropump without moving parts is discussed. The fundamental operating principles, such as high-frequency traveling waves, a self-stabilizing temperature gradient, and increased wave number, are outlined. main advantages of the realized pump its ability to move conductive liquids water weak electrolyte solutions, lack any movable parts, integration. microfabricated structure demonstrating operation outlined, quantitative results described. Typical...
