Abstract
 According to a unique nano-confi nement effect of entropic origin,
predicted by us several years ago for the equilibrium state of chemical
reactions, the equilibrium-constant and extent are greatly enhanced
depending on the small number of molecules involved, and for many
reactions also on the nano-space size. This work explored the validity
of this effect in the case of elemental dimerization reactions within
dilute alloy nanoparticles with separation tendency, Pd – Ir
cuboctahedra in particular. Employing a simple model for the system
energetics, computations based on the exact canonical partition-
function reveal nano-confi nement induced Ir2 dimer stabilization
within Pd surface segregated nanoparticles, refl ected e.g., by up to ~
60% increased dimerization extent and by doubling of the 1n KD vs. 1/T
slope, as compared to the macroscopic thermodynamic limit. The dual
role of the confi gurational entropy, namely mixing of Ir/Ir2 vs. Pd/Ir is
elucidated. Study based on more elaborate energetic models is
desirable as the next step of this research.

ZnO NPs (zinc oxide nanoparticles) has generated significant scientific interest as a novel antibacterial and anticancer agent. Since oxidative stress is a critical determinant of ZnO NPs-induced damage, it is necessary to characterize their underlying mode of action. Different structural and physicochemical properties of ZnO NPs such as particle surface, size, shape, crystal structure, chemical position, and presence of metals can lead to changes in biological activities including ROS (reactive oxygen species) production. However, there are some inconsistencies in the literature on the relation between the physicochemical features of ZnO NPs and their plausible oxidative stress mechanism. Herein, the possible oxidative stress mechanism of ZnO NPs was reviewed. This is worthy of further detailed evaluations in order to improve our understanding of vital NPs characteristics governing their toxicity. Therefore, this study focuses on the different reported oxidative stress paradigms induced by ZnO NPs including ROS generated by NPs, oxidative stress due to the NPs-cell interaction, and role of the particle dissolution in the oxidative damage. Also, this study tries to characterize and understand the multiple pathways involved in oxidative stress induced by ZnO NPs. Knowledge about different cellular signaling cascades stimulated by ZnO NPs lead to the better interpretation of the toxic influences induced by the cellular and acellular parameters. Regarding the potential benefits of toxic effects of ZnO NPs, in-depth evaluation of their toxicity mechanism and various effects of these nanoparticles would facilitate their implementation for biomedical applications.

ABSTRACT- In this study, the effect of ZnO and TiO2-NPs on beneficial soil microorganisms and their secondary metabolites production was investigated. The antibacterial potential of NPs were determined by growth kinetics of P. aeruginosa, P. fluorescens and B. amyloliquefaciens. Significantly decreased in the cell viability based on optical density measurements were observed upon treatment with increasing concentrations of NPs. While comparing the effect of the different concentrations of the NPs (200 µg/ml) on IAA production by different bacterial strains, ZnO nanoparticles showed greater inhibitory effect than TiO2-NPs on IAA production by bacterial strains. The effect of Nanoparticles on phosphate solubilization was found inhibitory at 200 µg/ml. Treatment with ZnO showed concentration dependent enhancement in siderophore production by bacteriaby exposure to ZnO-NPs whereas TiO2-NPs showed concentration dependent progressive decline for iron binding siderophore molecules. Reduction in antibiotic production by P. aeruginosa and P. fluorescens was noticed in the presence of ZnO and TiO2 as compared to the control. The fluorescence of NADH released by P. aeruginosa was observed to be quenched in presence of ZnO and TiO2-NPs as compared to control. The present study highlights that the impact of nanoparticles on bacterial strains and the release of plant growth promoting substances by PGPR strains was dose dependent, which gives an idea about the level of toxicity of these nanoparticles in the environment. Therefore, the discharge of nanoparticles in the environment should be carefully monitored so that the loss of both structure and functions of agronomically important microbes could be protected from the toxicity of MO-NPs.

Two- Step method has been applied to prepare stable In2O3 nano fluids in Ethylene Glycol with PVP (Polyvinyl pyrrolidone) used as stabilizing agent having In2O3 concentrations of 1% by volume, where the In2O3 nano particles are obtained by biosynthesis of Indium (III) Acetyl Acetonate and Gum Acacia. Since the two-step method is more versatile as it provides the opportunity to disperse a wide variety of nano particles in different types of base fluids. The nano fluids were characterised by UV-vis spectroscopy, FTIR, SEM, EDAX, and TEM, and systematically investigated for Thermal conductivity (TC), density, viscosity, specific gravity and electrical conductivity for different polymer concentrations. The size of nano particles was found to be in the range of 5-30nm for two different nano particle to PVP ratios. For higher concentration of polymer in nano fluid, nano particles were 20nm in size showing increase in Thermal conductivity but a decrease in density and viscosity which is due to the polymer structure around nano particles. It is observed that the viscosity, density & specific gravity increases with the increase in PVP concentration and decreases with temperature. The thermal conductivity measurements of nano fluids show substantial increment relative to the base fluid (Ethylene glycol). Effect of PVP Polymer on viscosity, density, specific gravity can have a significant effect on magnitude and behaviour of the Thermal conductivity enhancement confirming the Newtonian behaviour of nano fluid. This offers tremendous scope for developing compact and effective heat transfer equipment. An enhancement of 20-25% for 1:5 volume concentration are observed at an average voltage of 60V when compared with EG (Ethylene glycol) at the same voltage. This method is simple, fast and reliable for the synthesis of Newtonian nano fluids containing In2O3 nano particles.

Future prospects of nanotechnology innovations in animal production Ahmed Abdel-Megeed Department of Plant Protection, Faculty of Agriculture, Saba Basha, Alexandria University, Alexandria 21531, Egypt Corresponding author: ahmedabdelfattah@alexu.edu.eg Abstract Nanotechnology is a great innovation that is revolutionizing the agricultural practices. It is a science that works at the nanoscale and provides many benefits. In this review, the fundamental concepts of nanotechnology are clarified, focusing on its primary applications and a health and environment risk assessment especially in livestock production. There is currently a lack of reliable, cost-effective diagnostic tests for early detection of diseases in farmed livestock animals. Biosensing technologies have the potential to address these problems by developing innovative diagnostic tools for the rapid detection of key health threats within the agri-food livestock sector. It also allows for greater product innovation, with the creation of new food ingredients or supplements with nanoencapsulation or nanoemulsions, achieving a slow release of some composites, or perhaps obtaining healthier foods through the improvement of organoleptic properties in the product. Although nanotechnology provides many benefits, but as with all innovations, there are disadvantages and risks associated with its use. The risk assessment must take into account that the biokinetic profile and the toxicity in the target tissues can vary depending on which nanomaterial is being referred. A risk-benefit balance on the use of nanomaterials must be carried out, and in the majority of cases, though many people are open to the advancement, more information regarding the risks is required. Above all, it must be legally regulated to guarantee Agrofood safety in all products that have been manipulated using nanotechnology.

Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans. Motivated by recent JWST observations of K2-18 b, we self-consistently model the photochemistry and potential detectability of biogenic sulfur gases in the atmospheres of temperate sub-Neptune waterworlds for the first time. On Earth today, organic sulfur compounds produced by marine biota are rapidly destroyed by photochemical processes before they can accumulate to significant levels. Domagal-Goldman et al. suggest that detectable biogenic sulfur signatures could emerge in Archean-like atmospheres with higher biological production or low UV flux. In this study, we explore biogenic sulfur across a wide range of biological fluxes and stellar UV environments. Critically, the main photochemical sinks are absent on the nightside of tidally locked planets. To address this, we further perform experiments with a 3D general circulation model and a 2D photochemical model (VULCAN 2D) to simulate the global distribution of biogenic gases to investigate their terminator concentrations as seen via transmission spectroscopy. Our models indicate that biogenic sulfur gases can rise to potentially detectable levels on hydrogen-rich water worlds, but only for enhanced global biosulfur flux (20 times modern Earth’s flux). We find that it is challenging to identify DMS at 3.4 μm where it strongly overlaps with CH4, whereas it is more plausible to detect DMS and companion byproducts, ethylene (C2H4) and ethane (C2H6), in the mid-infrared between 9 and 13 μm.

Context. WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of the planet. The existence of this asymmetric signature has been confirmed by multiple studies, but its physical origin is still under debate. In addition, it contrasts with the absence of asymmetry reported in the infrared (IR) phase curve. Aims. We provide a more comprehensive dataset of WASP-76 b with the goal of drawing a complete view of the physical processes at work in this atmosphere. In particular, we attempt to reconcile visible high-resolution transit spectroscopy data and IR broadband phase curves. Methods. We gathered 3 phase curves, 20 occultations, and 6 transits for WASP-76 b in the visible with the CHEOPS space telescope. We also report the analysis of three unpublished sectors observed by the TESS space telescope (also in the visible), which represents 34 phase curves. Results. WASP-76 b displays an occultation of 260±11 and 152±10 ppm in TESS and CHEOPS bandpasses respectively. Depending on the composition assumed for the atmosphere and the data reduction used for the IR data, we derived geometric albedo estimates that range from 0.05 ± 0.023 to 0.146 ± 0.013 and from <0.13 to 0.189 ± 0.017 in the CHEOPS and TESS bandpasses, respectively. As expected from the IR phase curves, a low-order model of the phase curves does not yield any detectable asymmetry in the visible either. However, an empirical model allowing for sharper phase curve variations offers a hint of a flux excess before the occultation, with an amplitude of ∼40 ppm, an orbital offset of ∼−30◦ , and a width of ∼20◦ . We also constrained the orbital eccentricity of WASP-76 b to a value lower than 0.0067, with a 99.7% confidence level. This result contradicts earlier proposed scenarios aimed at explaining the asymmetry observed in high-resolution transit spectroscopy. Conclusions. In light of these findings, we hypothesise that WASP-76 b could have night-side clouds that extend predominantly towards its eastern limb. At this limb, the clouds would be associated with spherical droplets or spherically shaped aerosols of an unknown species, which would be responsible for a glory effect in the visible phase curves.

www.seribangash.com The Mariana Trench is one of the most remarkable geological features on Earth. Here are some details about it: Location: The Mariana Trench is located in the western Pacific Ocean, east of the Mariana Islands. It stretches for about 2,550 kilometers (1,580 miles) and is known as the deepest part of the world's oceans. Depth: The trench reaches incredible depths, with its deepest point known as the Challenger Deep, which plunges down to approximately 10,984 meters (36,037 feet) below sea level. To put this into perspective, if Mount Everest, the tallest mountain on Earth, were placed at the bottom of the Challenger Deep, its peak would still be over 2 kilometers (1.25 miles) underwater. Formation: The Mariana Trench was formed by the subduction of the Pacific Plate beneath the Mariana Plate. This process creates a deep trench as the heavier Pacific Plate is forced beneath the lighter Mariana Plate. Geological Features: The trench is characterized by steep, V-shaped valleys, and its walls are composed of highly compressed sedimentary rock. At the bottom of the trench, there are also large amounts of marine sediment. Pressure: The pressure at the bottom of the Mariana Trench is immense, reaching over 1,000 times the pressure at the surface. This extreme pressure creates a challenging environment for exploration and makes it difficult for organisms to survive. Exploration: Despite its extreme conditions, the Mariana Trench has been the subject of numerous scientific expeditions and explorations. One of the most famous explorations was the dive to the Challenger Deep by Swiss scientist Jacques Piccard and U.S. Navy Lieutenant Don Walsh in 1960. More recently, in 2012, filmmaker James Cameron made a solo dive to the bottom of the Challenger Deep in the Deepsea Challenger submersible. Biological Discoveries: Despite the harsh conditions, the Mariana Trench is home to a surprising variety of life forms, including unique species of deep-sea fish, crustaceans, and microbial life. Some organisms have adapted to survive in the extreme pressure and darkness of the trench. Environmental Importance: Studying the Mariana Trench provides valuable insights into the geology, biology, and oceanography of the deep sea. It also helps scientists better understand the processes that shape the Earth's crust and the distribution of life in the oceans. Conservation: Due to its remote location and extreme depths, the Mariana Trench has remained relatively untouched by human activity. However, there is growing concern about the potential impacts of deep-sea mining and pollution on this fragile ecosystem, highlighting the need for conservation efforts to protect this unique environment. https://seribangash.com/barber-shop-business-complete-guide-for-beginners/ https://seribangash.com/legend-virat-kohli-in-cricket-history/
