A Comprehensive Review on Mechanical based and AI based Natural Fibres Reinforced Composite Materials Nowadays, many people are shifting towards eco friendly materials because synthetic ones cause harm to the environment. Natural fibre based composites like jute, hemp, banana, and sisal are becoming popular since they are cheaper, biodegradable, and easy to produce. These materials are now being used in place of synthetic composites in civil, automotive, and packaging industries. Researchers have tested different combinations of natural fibres and biodegradable plastics to make strong and sustainable materials. This review talks about various types of natural fibres and their properties like strength, moisture resistance, and durability. It also explains how fibre treatment and the use of nanofillers can improve performance of composites. Some studies also show how these composites are being used in civil engineering for structural repair work and with the help of AI methods which have more influence on predicting, optimizing, and improving the mechanical and thermal qualities of composites made from natural fibres. AI can also be used in composite for major improvement in industries of automobiles and different constructions,with the help of AI we can do predictions for production process and maintaining high product quality with more efficiency.

The Effects of Temperature on CO2 Corrosion of Mild Steel in 3.5 wt.% NaCl: Corrosion Rate, Surface Morphology, and Phase Characterisation CO2 corrosion of mild steel constitutes a significant integrity threat within hydrocarbon transport systems. This work comparatively investigates the temperature-dependent corrosion behaviour of mild steel in CO₂-saturated and CO₂-free environments through weight loss test, surface morphology, and phase characterisation. Mild steel samples were exposed to two media, which are CO2-rich 3.5% NaCl solution and CO2-free 3.5% NaCl solution at 25°C, 40°C, 60°C, and 80°C for 7 days. Morphology changes, microstructure of corrosion products, cross sections, and phase characterisation were analysed using field emission scanning electron microscopy (FESEM), optical microscope (OM), and X-ray diffraction (XRD). Results from weight loss tests found that an increase in temperature resulted in an accelerated corrosion rate. However, in a CO2 environment, a decrease in corrosion rate was observed at higher temperatures, attributed to the emergence of protective layers. FESEM images revealed that mild steel in a CO2 environment underwent uniform corrosion, whereas localised corrosion was observed in the absence of CO2. The corrosion scales thickened with increasing temperature in both media; however, the development of a protective carbonate layer in the CO₂ environment inhibited further deposition, leading to a thinner final layer. XRD analysis confirmed the formation of siderite, hematite, and ferrous hydroxide in a CO2 environment, while cementite, hematite, and ferric oxyhydroxide were identified in a non-CO2 environment. These findings suggest that while temperature initially accelerates sweet corrosion, the emergence of a compact FeCO3 scale above 60°C transitions the behaviour to partial protection, guiding the developing temperature-dependent mitigation strategies and the application of nano-enabled monitoring in CO2-rich pipeline environments.

Gate-tunable fresnel zone plate based on single-walled carbon nanotubes for terahertz applications The active manipulation of electromagnetic waves through electrical tuning of nanomaterials is a key advantage for modern technology.We employed the tunable optical response of ionic-liquid-gated single-walled carbon nanotube (SWCNT) films to address a major challenge in terahertz (THz) optics -the limited range of materials with suitable optical properties.In this study, we demonstrated a high-performance THz intensity modulator combined with a focusing Fresnel zone plate (FZP) integrated in electro-chemical cell.We introduce a new approach for designing and fabricating the FZP, based on pre-measured dielectric properties of SWCNT films under applied voltage.The superior shielding effectiveness (up to 810 8 dB cm 2 g -1 ) of SWCNT films enables the creation of an ultrathin terahertz lens.Electrical gating doubled the minimum refractive index, enhancing lens performance.This also enabled in situ tunability of the intensity modulation depth, from +15 to -20 %, with an applied voltage of +2 to -2 V.Although the current switching time is 3.6 seconds, our work presents the first demonstration of an electrochemically gated SWCNT FZP, offering distinct advantages in tunability and thin-film design.Operating at 327 GHz, this FZP is a promising solution for novel adaptive THz communication devices.

Self-supervised domain adaptation of protein language model based solely on positive enzyme-reaction pairs There is growing interest in developing predictive models of enzyme catalytic properties that leverage activity data spanning diverse enzyme families. A fundamental challenge lies in the inherent biases of public biochemical databases. These databases predominantly catalog valid enzyme activities, rarely include negative instances, and report quantitative catalytic parameters for only a relatively small subset of enzymes. Such limitations pose a major obstacle to supervised learning of enzyme catalytic properties. One existing approach for model training involves generating synthetic negative enzyme-activity pairs by recombining existing enzymes and their activity information, particularly substrates or chemical reactions, that were not originally associated within datasets. However, it remains unclear whether the generated negative examples are truly inactive or merely unobserved active instances. To build a model that captures functional properties across diverse enzyme families while avoiding reliance on negative examples, this paper introduces a self-supervised domain adaptation methodology for pre-trained protein language models, solely based on positive enzyme-reaction pairs. The enzyme representations obtained from the adapted protein language model achieved superior or at least competitive performance compared to those from an existing method that relies on synthetic negatives, in both the turnover number prediction task for natural reactions of wild-type enzymes and the activity prediction task for family-wide enzyme-substrate specificity screening datasets. Overall, our approach represents a methodological advancement that eliminates the need for synthetic negatives and provides a scalable framework for leveraging the growing enzyme activity data in biochemical databases.

Synthetic Routes to Biomass-Derived Carbon Dots: a Mini-Review. Biomass-derived carbon dots (BDCDs) have emerged as sustainable photoluminescent nanomaterials for sensing, bioimaging, photocatalysis, and drug delivery, offering advantages of low cost, low toxicity, and waste valorization. BDCD properties - including particle size, quantum yield, surface chemistry, and emission wavelength - are critically influenced by the synthetic route and processing conditions, rather than the type of precursor alone. This mini-review systematically compares bottom-up methods (microwave-assisted, pyrolysis, hydrothermal/solvothermal) and top-down approaches (arc discharge, laser ablation, chemical oxidation), evaluating their influence on material characteristics and functional performance. Representative examples with quantitative data illustrate how reaction parameters control structural and photophysical properties. Critical analysis reveals persistent challenges, including batch-to-batch variability, structural ambiguity (between carbon dots and carbonized polymers), energy consumption ranging from 0.5 to 50 kWh/g, and inconsistent reporting standards. The review extracts empirical design rules that link synthesis conditions to target properties, compares BDCDs with conventional fluorophores, and assesses their environmental credentials. Directions for advancing the field include the development of standardized protocols, integration with renewable energy, comprehensive toxicological evaluation, and application-driven optimization to enable the transition from laboratory proof-of-concept to scalable, reproducible BDCD technologies.

MATHEMATICAL MODELING FOR PREDICTIVE BIOFILM-INDUCED STRESS CORROSION ON OIL PIPELINES Microbiologically influenced corrosion (MIC) in oil pipelines continues to pose a significant risk to energy infrastructure and public safety due to the intricate biofilm patterns and mechanical forces acting on them. In this work, we propose a spatially resolved predictive model that integrates laboratory assays with field inspection data for pitting prognosis that can be prevented by mitigation measures and is justifiable through experimental data. How? A coupled system of nonlinear partial differential equations is formulated for substrate diffusion, biofilm growth, detachment, and interaction with stress–corrosion at the surfaces of carbon steels. Laboratory boundary conditions were defined by linear polarization resistance and optical coherence tomography (OCT) biofilm thickness measurements in flow loops. Field parameters were obtained from inline inspection (ILI) data with ultrasound and electromagnetic sensors. An adaptive finite-element mesh for spatial heterogeneity in shear stresses (0.1–2 Pa) and flow velocities (0.5–2 m/s) was constructed in COMSOL Multiphysics and MATLAB. Model parameters (diffusivity, growth kinetics, some thresholds for detachment, and stress-intensity factors) were calibrated using Bayesian regression and global sensitivity analysis against empirical measurements of pit depth. Simulations demonstrate that spatially heterogeneous biofilm patches increase the rate of localized corrosion: high shear areas increased peak current density by 38 % and delayed biofilm maturation by more than 35%. The model, using calibrated parameters, demonstrated a field corrosion rate prediction with a root-mean-square error of 0.72 mA/cm². Incorporating sophisticated mathematical modeling with bench-scale and field data enables our tool to provide real-time risk assessments and insights, allowing for the optimization of pigging, biocide application, and maintenance scheduling. This approach sets a new vision for the future of pipeline operations by making them safer and more resilient.

Ultrasensitive and Selective Fluorescent Sensor for 5-Hydroxymethylfurfural Based on a Molecularly Imprinted Polymeric Nanocomposite A fluorescence sensor was designed based on nitrogen-doped graphene quantum dots confined in a metal-organic framework and molecularly imprinted polymer for the selective determination of 5-hydroxymethylfurfural (HMF). Morphological, structural, and spectroscopic characterizations, such as SEM, STEM, BET, FT-IR, and XRD, verified successful synthesis and imprinting with enhanced surface area and structural durability. The sensor demonstrated intense fluorescence at around 420 nm, which was quenched through photoinduced electron transfer (PET) by HMF, exhibiting a linear relationship up to 35 µmol L<sup>-1</sup> and a detection limit of 30 nmol L<sup>-1</sup>. It offered high imprinting efficiency, selectivity, and stability. The sensing platform also displayed efficient anti-interference performance toward interference species and presented excellent recovery in actual food samples such as honey, juice, and coffee, thus revealing the applicability of the sensing device for real-world HMF measurement in complicated matrices.

Understanding the origin of stereoselectivity in the photochemical denitrogenation of 2,3-diazabicyclo[2.2.1]heptene and its derivatives with non-adiabatic molecular dynamics Photochemical denitrogenation reactions of bicyclic azoalkanes produce strained bicyclic compounds of interest to synthetic organic chemists. We report a computational study on the mechanism of diazabicyclo[2.2.1]heptenes to address long standing mechanistic questions. Indeed, the mechanism of these reactions have been disputed for over six decades. We employed non-adiabatic molecular dynamics (NAMD) simulations combined with state-of-the-art multireference quantum mechanical calculations to understand the photophysical properties and mechanisms of these diazabicyclo[2.2.1]heptenes. The energetically accessible lowest excitations are n NN (σ CN ) → π* and range from 3.94 – 3.97 eV. From the &gt;292 trajectories, the reaction proceeds through a dynamically concerted but asynchronous denitrogenation reactions. One σ CN bond breaks along the S 1 -surface; the other σ CN breaks after hopping to the S 0 . We identified two clusters of S₁/S₀ surface hopping points from these trajectories. In the first cluster, the methylene bridge is fully inverted relative to the reactant geometry. In the second cluster, the inversion is only partial, with one of the carbon atoms in the methylene bridge inverted relative to the reactant. We identified each cluster's corresponding minimum energy conical intersection (MECI), indicating at least two possible S 1 /S 0 -MECIs. Our dynamics simulations illustrate that inversion begins in the excited state immediately after the first σ CN bond breaks. This inversion is driven by the atomic momenta acquired after the bond breaks. These dynamical effects promote the formation of the inverted housane, thereby explaining the observed selectivities. A minority of trajectories undergo thermal conversion in the ground state, producing the minor retained housane product from inverted housane.
