Scientific Developments of the Thermochemistry Department

color transition red → yellow at 65 °C, reversible at ≈ 53 °C.

Visual temperature indicator without electronics — immediate detection of overheating.

Single-layer application (suitable for screen, flexographic, and pad printing).

UV-resistant with repeatability over 10 000 cycles (requires verification under industrial conditions).

security markings on valuable papers, smart packaging for food and pharmaceuticals, color-changing toys, overheating control of device casings.

selection of binder systems for specific printing technologies and stability testing in serial conditions.

a series of labels with activation points from +2 °C to –20 °C (cooling) and +40 °C to +70 °C (heating).

Tunable palette (blue ↔ colorless, violet ↔ pink, etc.) ensuring clear color dynamics.

Safe formulation — components selected in compliance with EU Reg. 1935/2004.

Dual functionality: cold-chain integrity monitoring + anti-counterfeiting protection.

customized label design, printing specifications, and incoming quality-control procedures.

1.52 – 2.99 eV (adjustable during synthesis).

Charge-carrier mobility: 15 – 25 cm² V⁻¹ s⁻¹ — higher than typical organic perovskites.

Moisture stability: ≥ 500 h @ 85 % RH — simplifies encapsulation.

Recombination length: ≈ 1.1 µm — suitable for thick-film solar cells.

active layer in photovoltaic panels (covering the green-red window), high-efficiency LEDs (λ ≈ 550 – 650 nm), and photodetectors for IoT sensors.

partnership for fabrication of 1×1 cm² test cells (spin-coating / blade-coating).

iron(IV) clathrochelate complex with a bioavailable stabilizing ligand.

Improves hemoglobin levels and overall resilience of animals under post-stress conditions (confirmed by laboratory and model studies).

Demonstrates reduced incidence of anemic states and improved general condition of young livestock.

Does not cause local irritation after subcutaneous administration.

sterile solution — 50 mg Fe/ml.

pre-clinical toxicology studies under GLP standards and preparation for registration with EFSA and FDA/CVM.

Vanadium dioxide (VO₂) exhibits a “metal ↔ dielectric” transition at ≈ 68 °C.

Embedding VO₂ nanoparticles into a polymer matrix with contrasting dielectric permittivity enables controllable change of microwave parameters upon heating.

Δ|S₁₁| up to 28 dB within 8–12 GHz (X-band).

Functional-layer thickness ≤ 150 µm — applicable for spray coating.

Stability > 500 heating/cooling cycles without noticeable degradation.

Radar-absorbing and adaptive camouflage coatings.

Tunable microwave screens and reflective panels.

Active shutters and reconfigurable waveguide antenna elements.

composition optimization for target frequency ranges and joint validation on technological samples.
