Summary :
⁣We consider the effects of the external static magnetic field on the electronic and physical properties in the excitonic AA-stacked bilayer graphene. We have considered the effect of coupling between the magnetic field B and the spins $\sigma$, which results in the phase modulation of the particles in the system or the spin-dependent magnetic field $B_{\sigma}$. We have constructed the wave strings attached to the particles, for each given periodic interval of the phases, governed by spins. We have calculated the electronic band structure of the AA-bilayer, in the presence of transverse magnetic field and we have found the Metal-Semiconductor-Insulator transition in the AA-bilayer graphene, governed by the strength of applied magnetic field. The spins in our problem are considered as localized along the direction of applied field or opposite to it. The transition into Dirac’s spectrum of usual graphene is also discussed at certain band structure parameters regimes.

Summary :
⁣In recent years, due to its remarkable physicochemical properties, graphene has attracted attention in electrochemical reactions such as the hydrogen evolution reaction (HER) for hydrogen production [1,2]. Graphene can be prepared by efficient reduction of graphene oxide structure. In this study, the effect of oxidation time and graphite precursors on the formation of graphene oxide structure by Hummers’ method was investigated. Graphene oxide samples prepared with oxidation times of 24-72 h using two different graphite precursors (20μm and 150μm) were denoted as GO-2024, GO- 2048, GO-2072, and GO-15048. In the XRD patterns of GO-2024, GO-2048 and GO-2072 samples, the oxidation peaks of graphite were observed

Summary :
⁣Two-dimensional (2D) materials have shown great promise in next-generation devices due to their atomic thinness and broad electronic properties. To realize these post-silicon electronics, it will be necessary to electrically connect these 2D materials both in- and out-ofplane. However, the lattice mismatch between these atomic membranes leads to unavoidable strain, dislocations, or ripples, which can strongly affect the mechanical, electronic, and optical properties. This presentation will discuss using state-of-the-art four-dimensional scanning transmission electron microscopy (4D-STEM) techniques to address how different 2D materials merge to form lateral heterostructures. The study has enabled discoveries of the intricate and complex interface structures unique to 2D materials. Subsequent control or engineer of these deformations can profoundly impact future material and device development.

⁣The declining quality of the Erath’s environment and climate change has been challenging the mankind since centuries. Despite the detrimental effects, plastics serve in a wide range of applications due to various properties like high strength, durability, transparency, corrosion resistance, low toxicity, and lightweight. Multifarious industries ranging from food packaging to space exploration tend to use plastics which leads to the immense pollution. Bio-based polymers have proved to be potential countermeasure to for plastic pollution and have thus drawn plentitude attention from the researchers in the recent years. In view of the above, bio-based carbon serves as an excellent filler for thermoplastics which can be used for diverse applications. The carbon is synthesized from the waste coconut shell powder by using high temperature/pressure reactor. Furthermore, Iron acetyl acetonate is used as catalyst and is loaded with 1 , 2 and 3 wt% in the coconut shell powder and is magnetically stirred for 3hrs in chloroform to obtain homogenous dispersion of catalyst in the coconut shell powder. The pyrolysis is conducted with heating rate of 10°C/min from room temperature to 1000°C and was held for 2 hrs isothermally. Thus derived carbon was ultrasonicated for 3hrs in the presence of ethanol and was characterized using SEM, Raman and XRD.

Summary :
⁣Copper oxide (CuO) loaded titanium dioxide (TiO2) nanotube photocatalyst was synthesised using the facile hydrothermal method. The synthesised photocatalyst were characterised by X-ray diffraction (XRD), field emission scanning microscopy (FESEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) to study their physiochemical properties. The photocatalytic activity of the photocatalysts was tested for carbon dioxide (CO2) photoconversion and methyl orange degrdadation. CuO loaded TiO2 nanotube demonstrated higher CO2 conversion (100%) and methyl orange degradation because of the former’s effective separation of photogenerated electron-hole pairs in the presence of CuO.

Summary :
⁣Corrosion is considered to be major challenge faced by oil and gas industry which becomes more disastrous in heavy operating conditions. In this research, zirconia nanoparticles were incorporated in NiP matrix to study the effect of concentration of ZrO2 particles in the NiP-ZrO2 nanocomposite coatings. Low alloy steel was used as the substrate and pulse electrodeposition technique was utilized owing to its advantages over other deposition methods. Co-electrodeposition of various concentrations of zirconia nanoparticles (0.0, 0.25, 0.50, 0.75, and 1.0 g/L) was carried out in the optimized chemical bath. Numerous techniques were adopted to evaluate the structural, morphological, mechanical and electrochemical properties of nanocomposite coating. SEM and EDS results prove the successful reinforcement of zirconia nanoparticles in NiP matrix. XRD and XPS analysis validates the structural formation of pure phase of NiP without any evident defect. An appreciable enhancement in the mechanical properties was noticed with an increase in the amount of zirconia nanoparticles. Likewise, EIS analysis confirms a gradual increase in corrosion protection behavior of the NiP-ZrO2 nanocomposite coatings with increasing zirconia concentration. The decent mechanical and corrosion resistance properties of NiP-ZrO2 nanocomposite coatings provide an exciting option for their suitability in numerous applications.

Summary :
⁣Extravasation is a major problem especially among the pediatric population. Extravasation is defined as infiltration or leakage of an intravenous chemotherapeutic agent into the surrounding tissue which results in local damage.The various types of extravasation causing agents can be Sclerosing,fibrosing agents.Drugs that can cause blisters,ulceration, severe tissue destruction & necrosis. Eg.. Vincristine.or drugs that can cause burning and inflammation.eg.. Dacarbazine. Usually cause extravasation. Two major mechanisms are believed to cause tissue damage,DNA binding vesicant agents (e.g., anthracyclines) Absorbed by local cells in the tissue and bind to DNA,causing cell death.Non DNA binding vesicant agents (e.g., vinca alkaloids)These agents do not bind to cellular DNA.Local tissue damage is more easily neutralized than damage to surrounding tissues. Pediatric nurses play a major role in preventing extravasations occurring and also managing the extravasations on time to prevent complications which even can be fatal.The aim of this presentation is to high light the role of nurses in preventing and managing extravasations in the hospital.

Summary :
⁣The egde functionalization of graphene layers was performed with biosourced C-3 and C-6 molecules, glycerol and galactaric acid derivatives: pyrrole compounds and 2-pyrones, respectively. Their synthesis and the functionalization of the graphene layers were done in line with the principles of green chemistry, avoiding solvents and catalysts, by simply mixing them with the graphitic material, with the help of either thermal or mechanical energy. High functionalization yield, up to 96%, high atom efficiency and very low E Factor were obtained. The bulk structure of the carbon substrate was left substantially unaltered, as demonstrated by X-ray and Raman analysis. Functional groups of defined chemical structure were covalently bound to the edges of the carbon material and the adducts were found to be stable up to very high temperature (> 200°C).

Summary :
⁣Rapid manufacturing on space/air/sea/land missions, where either gravitational force is missing or severe random disturbance may present continuously, is highly in demand. However, till today, there is no reliable technique for such working environments. The purpose of this study is to develop a technology for rapid 3D printing in solid state of polymeric materials to get rid of the problems in harsh working environment. The basic concept is to cross-link by either UV-light or photo-induced-heat of polymeric materials in the solid state for rapid volumetric additive manufacturing. The uncross-linked parts can be removed by heating or cooling for melting, or washing away by solvent. Finally, the shape memory effect (SME) of the cross-linked polymers is applied to ensure high accuracy of the printed items. We have successfully demonstrated this concept using thermal gel, UV cross-linkable vitrimer and other conventional materials.

Summary :
⁣A large number of genetically determined diseases have phenotypic manifestations in the form a large number of small anomalies of development, resistant, convulsive syndrome, psychomotor developmental delay syndrome, which can be used in the diagnosis of these diseases, starting from neonatal period. In order to carefully analyze the phenotype was used a specially designed scale - the scale of phenotype analysis (SAF) The use of this scale for additional examination of a newborn made it possible to suspect, and subsequently verify genetically determined diseases in 20% of the examined children. Comprehensive phenotype research can be used to optimize the diagnosis of genetically determined diseases. Careful study of the phenotype allows to diagnose genetically determined conditions, starting from the newborn period. The use of a phenotype assessment scale is available a fairly simple, inexpensive method of diagnosis that does not require additional equipment and special training.

Summary :
⁣In order to provide experimental guidance, a theoretical study was performed on transparent conduction oxide (FTO)/TiO2/interface defect layer 1/CH3NH3SnI3/interface defect layer 2/Cu2O/ back contact solar cell. The simulation was performed under the illumination of 1000 W/m2, at 300 K and an air mass of AM 1.5G. The diffusion lengths of electron and hole were set to 260 nm and 560 nm in absorber layer, respectively. The set value is very near to recently observed experimental values. The device performance is severely influenced by the thickness of absorber layer, acceptor density, defect density and work function of various back contact electrode materials. Oxidation of Sn2+ into Sn4+ was considered and it is found that the reduction of acceptor concentration of absorber layer significantly improves the device performance. Further, optimizing the defect density (1014 cm−3) of the perovskite absorber layer, encouraging results of the Jsc of 40.14 mA/cm2, Voc of 0.93 V, FF of 75.78% and PCE of 28.39% were achieved. This theoretical simulation provides an appropriate direction for devolving photovoltaic technology.

Summary :
⁣Twist angle between the adjacent layers of Transition Metal Dichalcogenides (TMDCs) provides an exotic degrees of freedom to tune the various optical and electrical properties in the field of twistronics. To realize the practical applications of twistronics, it is importance to tune the interlayer twist angle on large scales as the varying twist angle results in strong tuning of the indirect optical transition energy and Raman modes. In this work, we demonstrate the tunable Photoluminescence (PL) properties and the Raman modes of bilayer WSe2 through interlayer twist with a wide angle variation. PL and Raman spectra show that the interlayer coupling is highly sensitive to twist angle. Here, the stacking of CVD grown WSe2 bilayers was varied from 00 to 600 angle, which leads the homo-bilayer from AA to AB stacking orientation with a 60° periodic change of their PL spectra. We observed that, the twist angle can continuously change the indirect band-gap trion state at Q-K point in WSe2 homo-structures. At room temperature, the exciton and trion states are present at 00 twist angle and with increase in the twist angle, the indirect trion state dominates over the excitonic state. This PL modulation is attributed to the change of the interlayer coupling between the adjacent WSe2 layers. A systematic variation of Raman modes also revealed the manipulation of phonons with the twist angle in WSe2. These results enrich the understanding of the PL emission and interlayer coupling, which is significant in the field of twistronics.

Summary : ⁣With the growing demand for alternative energy (especially plant biomass) and to avoid competition with traditional food crops, part of the less-favored areas may be used for energy crops. LAMMC Vėžaičiai branch (Lithuania) has been conducting research on 2 perennial fast-growing plant species (herbaceous and woody) in the acidic whitish soils (pH 4.2-4.4) of Western Lithuania since 2009 and 2014. The effect of liming (to adjust the optimal soil pH level) and nitrogen fertilizers on biomass growth was investigated. The increase in dry weight of cocksfoot (Dactylis glomerata L.), reed canary grass (Phalaris arundinacea L.) and common osier (Salix viminalis L.) was directly related to nitrogen fertilization alone. Liming and fertilization with nitrogen fertilizers and their interaction had a positive effect on the productivity of the following plants: black poplars (Populus nigra L.), cup plact (Silphium perfoliatum L.), virginia mallow (Sida hermaphrodita Rusby). Except for virginia mallow, the effect of liming on other plants is more pronounced only in the first few years of plant growth. However, primary soil liming had a positive effect on soil chemical parameters (especially humus growth) and microbiological activity.

Summary :
⁣The interface between two-dimensional semiconductors and metal contacts is an important topic of research of nanoelectronic devices based on two-dimensional semiconducting materials such as molybdenum disulfide (MoS2). Although the effects of various contact metals on transport properties of MoS2 flakes were investigated in many prior studies, they have not been fully understood. Exploring the effects of contact metals and understanding the mechanism behind the effects of contacts remain necessary. We found that transport properties of thin MoS2 flakes with Al contacts were quite different from those contacted by Au, Ti, etc. The conductance of flakes with Al contacts exhibits a smaller gate-voltage dependence, which is consistent with a substantial electron doping effect of the Al contacts.
