Carbon nanotubes (CNTs) are a class of materials that exhibit many special properties. So far, little is known about their environmental impact and ecotoxicological risk. These tubes, however, can accumulate in living organisms and enter living cells. CNTs are regarded as advanced materials in drug and gene delivery vectors, where the exact mechanism for the intake of CNTs as the cellular membrane is not clear. Herein, the interaction of COOH functionalized CNTs with artificial membranes is studied via combined experimental and computational approaches employing infrared and Raman spectroscopy and quantum chemical calculations. The related physicochemical features of the CNTs toward their role in drug delivery systems are discussed.

In recent years, there has been a lot of interest in the use of fuzzy logic-based control systems to construct autonomous drone vehicles. This method makes use of fuzzy logic's adaptability and flexibility to guide drones safely through challenging surroundings. This study gives a comprehensive framework for the design and implementation of fuzzy logic-based control systems for autonomous drone vehicles. The three primary parts of the proposed framework are perception, decision-making, and control. The perception module processes sensor input, including visual and depth data, to provide accurate representations of the world. The decision-making module interprets the perception data and uses fuzzy logic methods to arrive at sensible choices for navigation and obstacle avoidance. The fuzzy logic system's decisions are converted by the control module into the right control signals that the drone will follow. The fuzzy logic-based control system also shows resilience and adaptation to changing environmental circumstances and uncertainties, making it appropriate for real-time applications. New opportunities for autonomous drone applications, such as surveillance, delivery services, and search and rescue missions, are made possible by the adoption of this architecture. Using fuzzy logic-based control systems to create autonomous drone vehicles is a viable way to provide effective and precise drone navigation in challenging conditions. By offering a holistic framework that blends perception, decision-making, and control utilizing fuzzy logic approaches, this research advances the development of autonomous systems.

Abstract There is an urgent requirement for drug discovery and more importantly drug repositioning due to infectious new Severe Acute Respiratory Syndrome coronavirus 2. As per the recent report published in the journal L'Encéphale in May 2020, there is a planned ReCoVery Study examining the repurposing the chlorpromazine for the treatment of COVID-19. Here, we apply a combined Raman microspectroscopy and DFT-MD approach to investigate the structural dynamics of the Chlorpromazine (CPZ) drug with dipalmitoylphosphatidylcholine (DPPC) lipid bilayer, identifying the specific position of the drug in the DPPC lipid bilayer. The intensity ratios of the Raman peaks I 2935/I 2880, I 1097/I 1064 and I 1097/I 1129 are representative of the interaction of drugs with lipid alkyl chains and furnish conformation of lipid alkyl chains. Raman imaging microscopy for the study of the distribution of CPZ inside the lipid vesicles is reported. We also investigated the influence of order and disorder ratio in the CPZ on the DPPC liposomes prepared on phase transition temperature. HIGHLIGHTS Drug–membrane interactions using micromolar concentrations of both lipid and drugs. Neuroleptic drug and DPPC vesicles composed of DPPC/drug mixtures reveal qualitative differences between the Raman spectra The temperature-controlled Raman microspectroscopic study has demonstrated that below phase-transition temperature, the fatty acid chains of the phospholipids are stiff and packed in a highly ordered array. DFT and MD simulations to understand molecular interactions, structural dynamics, and Raman spectra. Above phase-transition temperature, the chains are disordered and possess more motional freedom.

ABSTRACT This work reports the interaction between neuroleptic drug, chlorpromazine, with dipalmitoylphosphtidylcholine (DPPC) lipid. Density functional theory was applied to assess the changes caused by chlorpromazine (CPZ) and to specify the exact location of the drug in the lipid. It is found that the incorporation of drugs in DPPC causes a concentration dependent increase of the membrane fluidity and they interact strongly with both the lipophilic part and the polar head group of the phospholipids. The results obtained from molecular electrostatic potential surface have shown that the amino groups interact with the negatively charged phosphate groups of the phospholipid molecules and the aromatic rings are directed towards the hydrophobic interior of the phospholipid membrane. The calculated HOMO and LUMO energy gap explains the charge transfer phenomenon within the molecule.

Layered zirconium hydrogen phosphate intercalation compounds can be easily tuned, leading to potential applications in many fields, specifically by introducing them in different polymeric composites as nanofillers. Employing first-principles density functional theory based calculations, we have investigated ground state electronic structure properties of α-zirconium hydrogen phosphate (α-ZrP). We discuss the structure and electronic band structure, where projected density of states calculations have been discussed to understand the different atomic orbitals contributions to electronic bands. ZrP has numerous properties of interest for use in many semiconductor device structures, specifically, layered zirconium hydrogen phosphate has substantial promise for both optical devices and for high power electronics due to its large direct band gap. Our structural calculations suggest that layered zirconium hydrogen phosphate exhibits monoclinic structure. The calculated structural parameters and band gap are in good agreement with available experimental data.

ABSTRACT In the present study, variable temperature FT-IR spectroscopic investigations were used to characterize the spectral changes in oleic acid during heating oleic acid in the temperature range from −30°C to 22°C. In order to extract more information about the spectral variations taking place during the phase transition process, 2D correlation spectroscopy (2DCOS) was employed for the stretching (C˭O) and rocking (CH2) band of oleic acid. However, the interpretation of these spectral variations in the FT-IR spectra is not straightforward, because the absorption bands are heavily overlapped and change due to two processes: recrystallization of the γ-phase and melting of the oleic acid. Furthermore, the solid phase transition from the γ- to the α-phase was also observed between −4°C and −2°C. Thus, for a more detailed 2DCOS analysis, we have split up the spectral data set in the subsets recorded between −30°C to −16°C, −16°C to 10°C, and 10°C to 22°C. In the corresponding synchronous and asynchronous 2D correlation plots, absorption bands that are characteristic of the crystalline and amorphous regions of oleic acid were separated.

The Fourier transform Raman and infrared (IR) spectra of the Ceramide 3 (CER3) have been recorded in the regions 200–3500 cm− 1 and 680–4000 cm− 1, respectively. We have calculated the equilibrium geometry, harmonic vibrational wavenumbers, electrostatic potential surfaces, absolute Raman scattering activities and IR absorption intensities by the density functional theory with B3LYP functionals having extended basis set 6-311G. This work is undertaken to study the vibrational spectra of CER3 completely and to identify the various normal modes with better wavenumber accuracy. Good consistency is found between the calculated results and experimental data for the IR and Raman spectra.

A systematic quantum mechanical study of the possible conformations and vibrational spectra of 2-amino 6-bromo 3-formylchromone has been reported. The equilibrium geometry, harmonic vibrational frequencies, infrared intensities and activities of Raman scattering were calculated by Hartree–Fock and density functional theory employing Becke's three-parameter (local, non-local and HF) hybrid exchange functionals with Lee–Yang–Parr co-relational (B3LYP) functionals using 6-311++G(d,p) basis set with complete relaxation in the potential energy surface. The calculated wavenumbers after proper scaling show a very good agreement with the observed values. The electrostatic potential mapped onto isodensity surface has been obtained. The natural bond orbital analysis has been carried out in order to study the intra-molecular bonding, interactions among bonds and delocalisation of unpaired electrons. The highest occupied molecular orbital–lowest unoccupied molecular orbital studies have been conducted in order to determine the way the molecule interacts with other species.
