Our research if focussed on fundamental light-matter interactions at a spatio-temporally confined conditions and its development towards advanced ultrafast laser 3D nanolithography (also known as Two-Photon Polymerization or Multi-Photon Lithography – 2PP / MPL).
The femtosecond laser direct writing (LDW) approach enables 3D printing with down to 100 nm feature dimensions of true free-form structures reaching dimensions up to mm in their overall sizes. It is compatible with diverse materials ranging from plant derived renewable resins to high technical performance offering hybrid polymers as well as inorganics - glasses, ceramics, and crystalline substances.
Such additive manufacturing technique allows production of various high-resilient and heavy-duty components applicable for micro-optics, nano-photonics as well as biomedicine.
Scientific research topics:
- Photophysical mechanisms influencing the nanoprocessing of materials with ultrafast lasers;
- Optical micro-/nano-printing of functional prototypes;
- Creation and characterization of a new generation integrated nanophotonic, microoptical, miomedical and microfluidic components;
- Development of additive and subtractive 3D laser mesoscale fabrication technologies (monolithic structures with nano- and macro-architecture out of different materials);
- Research of alternative optical 3D printing and soft lithography techniques and their applications.

Project description:
Darbas vykdytas lazerių fizikos, optikos, medžiagų mokslo ir chemijos mokslų sandūroje, siekiant įsisavinti ir panaudoti modernias tiesioginio rašymo technologijas daugiafunkcinių mikrooptikos ir nanooptikos komponentų formavimui bei integruoti juos į jau naudojamus lustus. Tiesioginio rašymo technologija vienu etapu leidžia sukurti reikiamos formos ir paskirties daugiafunkcinius mikrooptikos komponentus įvairiems taikymams pagrįstiems šviesos valdymu mikrometriniame mastelyje. Pagrindinės taikymo sritys yra telekomunikacija, mikroskopija, biologija ir medicina, lazerinių šaltinių gamyba, saulės elementų pramonė. Naudojant elektronų pluošto litografiją galima suformuoti itin aukštos erdvinės skyros nanometrinių matmenų planarinius optinius elementus.
Pagrindinis teikiamo projekto tikslas – įgyti supratimą ir eksperimentinę patirtį kaip tiesioginio lazerinio ir elektronų pluošto rašymo būdais galima formuoti įvairius mikrooptikos ir nanooptikos komponentus iš naujos kartos hibridinių organinių-neorganinių fotopolimerų, ištirti to ypatumus, apibūdinti tokių darinių optines savybes ir palyginti su teorinėmis vertėmis. Siekiant šio tikslo numatoma spręsti keletą uždavinių: vystyti ir optimizuoti darinių įrašymo polimeruose procesą bei jų ryškinimą po švitinimo, atrinkti optimalias hibridines medžiagas, tinkamas mikrooptinių ir nanooptinių komponentų formavimui ir jų taikymui, įvertinti komponentų kokybę ir charakterizuoti jų veikimą, įvertinti eksperimentinių rezultatų atitikimą modeliniams skaičiavimams.
Įvykdžius projektą išvystytas lankstus reikiamos formos funkcinių mikrooptikos ir nanooptikos elementų formavimas, pvz.: mikrolęšiai su fazinėmis gardelėmis, Frenelio, asferiniai ir cilindriniai bifokaliniai mikrolęšiai bei jų masyvai. Taip pat bus išbandyta ir išmokta juos formuoti ant įvairių paviršių (stiklo, metalo, silicio) ir integruoti į jau esančias sistemas (šviesolaidžio galas, mikrofluidiniai ir optofluidiniai lustai, saulės baterijos).

Project description:
Osteoarthritis is a degenerative joint injury, especially prevalent among older people. This is among the most common causes of pain and disability in the world. Osteoarthritis is usually the end result of cartilage damage, which tends not to heal spontaneously. Despite the growing number of articular cartilage damage, there is still no effective cartilage structure restoring treatment.
Recently, much attention is being paid to biological cartilage regeneration to repair hyaline cartilage tissue and delay disease progression. Articular cartilage lesions are successfully treated using autologous chondrocyte implantation for more than 20 years. In order to increase the effectiveness of treatment, it is necessary to improve procedures for cell isolation, cultivation, and growing on the scaffold. To justify this strategy we previously conducted a proof‐of‐concept study which has produced positive results on the ability of cells to proliferate, express chondrogenic markers; cells biocompatibility with microstructured scaffold was evaluated on morphological, histological, molecular levels; characterization was carried out at every stage and in vivo preclinical study showed that the therapeutic cellular product is biocompatible, safe, efficient for regeneration of cartilage tissue.
The planned study represents further steps of our scientific research with a focus on elucidation of product biocompatibility and clinical translation. The project aims to develop and characterize the most effective microstructured scaffold with animal (rabbit) and human cells. Results of our original work will be applied in search for an optimal type of scaffold and production methods. Formed construct will be used in preclinical model, and treatment safety and efficacy will be compared with positive and negative control groups. In case positive results will be obtained, newly acquired data can be adapted for clinical applications.

Review of the Current Object Detection Methods Used in NTUU KPI (Kyiv, Ukraine)
2.1. YOLOv4 - Context-Aware Data Augmentation for Efficient Object Detection by UAV Surveillance.
Abstract
The problem of object detection by YOLOv4 deep neural network (DNN) is considered on drone dataset with object classes (pedestrians, bicyclists, cars, skateboarders, golf carts, and buses) collected by Unmanned Aerial Vehicle (UAV) video surveillance. Some frames (images) with labels were extracted from videos of this dataset and structured in the open-access SDD frames (SDDF) version (https://www.kaggle.com/yoctoman/stanford-drone-dataset-frames). The context-aware data augmentation (CADA) was proposed to change bounding box (BB) sizes by some percentage of its width and height. Several CADA-sequences were analyzed and the best strategy consists in first-IN-then-OUT CADA procedures, where the extent of decrease and increase of BBs width and height can be different for various applications and datasets
2.2.Example 2: YOLOv5 family - Object Detection for Rescue Operations by High-altitude Infrared Thermal Imaging Collected by Unmanned Aerial Vehicles.
Abstract
The analysis of the object detection deep learning model YOLOv5, which was trained on High-altitude Infrared Thermal (HIT) imaging, captured by Unmanned Aerial Vehicles (UAV) is presented. The performance of the several architectures of the YOLOv5 model, specifically ’n’, ’s’, ’m’, ’l’, and ’x’, that were trained with the same hyperparameters and data is analyzed. The dependence of some characteristics, like average precision, inference time, and latency time, on different sizes of deep learning models, is investigated and compared for infrared HIT-UAV and standard COCO datasets. According to the findings, the significance and value of the research consist in comparing the performance of the various models on the datasets COCO and HIT-UAV, infrared photos are more effective at capturing the real-world characteristics needed to conduct better object detection.
2.3.Example 3: The Other Current Object Detection Methods and Future Plans Proposed by NTUU KPI (Kyiv, Ukraine)
Abstract
The real-world (from Russia’s war on Ukraine) UAV experience collected by the authors and end users will be reviewed in the context of possible application of advanced optical systems and AI-ML-DL-based methods.

Review of the Current UAV Navigation Methods Used in NTUU KPI (Kyiv, Ukraine)
Abstract
The current UAV operation experience collected by the authors and end users will be reviewed in the context of possible application of advanced optical systems and UAV navigation methods under field conditions in the dangerous operation zones.
Demo Conditions: The further details will be provided later, but at the moment we assume that any “playground” with the sizes (100 m * 100 m * 50 m) which is free of any objects will be sufficient to demonstrate the basic concepts and ideas. It could be like an empty football field or any kind of grass field, lawn, etc. This “playground” is assumed to be used for the further experiments at LRC.
