      Soot
      Soot production is an inevitable process connected with solid fuel combustion. Soot is a complex substance, its chemical composition can vary a lot. Usually it includes ashes and tarry substances. They are generated mainly during combustion of coking coal. Furthermore, soot can form deposits, which are very difficult to remove.
      Soot deposition in boilers and on chimney walls can lead to potentially risky situations and economic losses, e.g.: soot ignition in flue, decrease in boiler thermal efficiency, increase in fuel usage, inefficient ventilation, increase in carbon monoxide (CO) concentration in exhaust fumes, flues blockage, air pollution.
      Application of solid fuel additives may improve fuel combustion efficiency and contribute to environment protection.

      Solid fuel additive
      Presented solid fuel additive can be used with bituminous coal (black coal), lignite (brown coal), coomb, coke, anthracite, peat, pellets, briquettes and wood. The additive is intended for low-power household boilers.
      The additive is ecological and environment-friendly, since it:
       reduces soot production and consequently improves boiler thermal efficiency and fuel combustion effectiveness,
       lowers costs of heating,
       decreases combustion temperature of soot what minimizes soot deposition on chimney walls, flues and boiler installation,
       modifies soot composition – soot becomes biodegradable and boosts plants growth,
       prevents releasing soot-related pollutions such as: polycyclic aromatic hydrocarbons (PAH), stable organic radicals and heavy metals,
       does not contain compounds which are very harmful to environment,
       does not cause boiler corrosion,
       is not harmful to human health.
      How does the additive work?
      Solid fuel eco-additive is inserted into furnace together with fuel or strewn onto fuel surface. The additive components are activated in temperature range from 80 to 650°C. The additive formula comprises of two components kinds: those which decompose in high temperature releasing oxygen and those which catalyze complete fuel combustion.
      Due to additive presence, soot starts to burn in much lower temperature (300°C) than in situation when there is no additive added (usually soot burns in temperature over 700°C). The additive aids much easier and faster oxygenation of soot deposition overlaying chimney and flues.
      Dose: 0.5-2 kg of the additive for 1000 kg of fuel. When used regularly, 50 g of the additive should be applied once a week.

      Ecological solid fuel additive for reducing soot generation is the subject of patent application.
      Currently the Centre for Technology Transfer CITTRU is looking for entities interested in licensing and commercial application of described solution.

          Description

          Key facts:
          - Lead structures classified as multimodal agents (serotonin, dopamine receptors ligands)
          - Lead structures display anti-psychotic, pro-cognitive and pro-social efficacy; the latter suggesting favorable effects on negative symptoms of psychoses
          - Uncomplicated synthesis
          In vitro testing:
          - Compounds display high affinity for dopaminergic D2 and D3 receptors and serotoninergic 5-HT1A, 5-HT2A, 5-HT6, 5-HT7 receptors; they were mostly classified as D2, 5-HT2A antagonists
          - Compounds have no affinity for M1, H1 lowering the risk of side effects related to cholinergic-, histaminergic- activity
          - Lead structures are brain penetrant
          - Lead structures display acceptable CYP interaction, no toxicity (hERG)
          In vivo testing:
          - Favorable profile in tests predictive of anti-psychotic activity: PCP-induced hyperactivity, conditioned avoidance response (CAR), prepulse inhibition (PPI), social interaction
          - Pro-cognitive efficacy in the novel object recognition (NOR) test, attentional set shifting (ASST), and others suggesting an enhancement of prefrontal flexibility disturbed in schizophrenia
          - Activity was confirmed following oral administration
          - Lead structures don’t affect ECG in guinea pigs and show lack of cardiovascular effects in rats, suggesting the lack of cardio-toxicity

          Compounds may be regarded as drug candidates for the treatment of schizophrenia symptoms and cognitive impairment.

            Description

            The object of the present invention is a photovoltaic cell made of silver nitrate and rochelle salt (potassium sodium tartrate), which provides a higher efficiency that the commercial ones due to driving the piezoelectric effect and the properties materials, these ones also making it cheaper because is not made of silicon.
            Currently there are photovoltaic/solar cells, to capture solar energy and transform it into electrical energy. One of the materials currently used is silicon, therefore the end the object of this invention is to create a cell capable of producing up to 3 times the energy of existing cells, making it flexible and easy to manufacture, since it does not require vacuum systems and can be manufactured in different shapes and dimensions. With far more advantages than conventionals.
