Technology
TOUA20171225001
Offers
There is growing demand for organic food now in the world. Therefore, the development of organic farming is becoming a popular business. This allows to predict a steady market demand for organic fertilizers. Biohumus is used as the main organic fertilizer at planting, fertilizing all types of agricultural crops, forestry, horticulture, as well as resuscitation and soil restoration. Ecological products company allow to enrich plants with humic and fulvic acids, increase the fertility of the soil. Fertilizer is easy and gradually absorbed by plants during their life cycle.

Technology
TODE20190416002
Offers
Wastewater sludge is becoming increasingly difficult to dispose of. Due to new environmental regulations more restrictions apply for using municipal wastewater sludge as fertilizer in agriculture. For incineration purposes or use as biomass the sludge needs to be dewatered. If the sludge is to be disposed of, each percentage in volume reduction leads to savings. The low energy microflotation wastewater treatment technology developed by a German engineering company has proven most effective in sludge thickening.

A novel approach for reaching highly effective antibacterial action using activated gold

Technology
TOSI20190415001
Offers
A novel approach in which activated gold particles are used has been invented for formation of material with reduced toxicity and increased antibacterial activity. Gold nanoparticles, which are naturally inert for living organisms and ineffective against bacteria, are combined with ceramics and carefully selected organic biomolecules into composites with very high antibacterial activity. This material has been activated for antibacterial activity in such a manner that it is twice as efficient as compared to silver.

Optimized circuit for high frequency energy harvesting

Offers
A German university offers a dynamic range extender for the recovery of electrical energy from electromagnetic radiation. There are different approaches to power electronic devices. Possibilities exist to charge via the so-called "energy harvesting" batteries or to provide a direct source of energy. As an example: the energy of electromagnetic radiation in the 2.4 GHz band can be used for this. However, the efficiency of such devices decreases rapidly with decreasing power. The basic structure of this invention is the balanced rectifier as it can be seen in the picture.

Improved bass sound quality for small speaker enclosures

Technology
TODE20190312005
Offers
Loudspeaker enclosures for low frequency reproduction face the developer with a goal conflict. Either he achieves a small volume enclosure or he achieves a low cutoff frequency. One approach to overcome this shortcoming is the well-known vented enclosure. However, the commonly utilized resonator ports cause other issues, such as flowing noise and delay differences between driver and port. Due to this delay, vented designs suffer from worse phase response compared with sealed enclosures.

Liquid concentrate extender for short-time preservation of boar semen

Technology
TOCZ20190329001
Offers
A liquid form of a concentrate for the dilution and preservation of boar semen should assure first of all easy and simple preparation for insemination of sows. At present mostly only powder diluted solution is used, which is complicated to prepare and takes longer time. The Czech animal breeding institute has developed a liquid form of an extender concentrate for the dilution and preservation of boar semen. The dilute solution can be stored in a plastic bottle for up to 4 months, and individual doses can have a shelf-life up 2-3 days as well as being faster to prepare.

Increased capacity for optical transmission systems

Technology
TODE20190312003
Offers
In very thin waveguides only one mode can propagate, in thicker waveguides several modes are possible. If several modes are transmitted, each mode can transmit data and the data flow is increased. A German university now developed such an optical transmission system: A plurality of signals of different modes per wavelength is generated on the transmitter side. The signals are then combined via a mode multiplexer and a wavelength division multiplexer and coupled to a fiber. The order of multiplexing is freely selectable.
