This study investigates the effects of Cu content (1.35, 3.10, and 6.01 wt.%) on hydrogen diffusion behavior and hydrogen embrittlement resistance in Cu x Ni 2.7 Mn low‐carbon steel, supplemented by numerical simulations using a cellular automata (CA) model. Through hydrogen permeation experiments, mechanical property…
Multi-layer flexible packaging has been widely adopted in the food, pharmaceutical and industrial sectors, as it can balance mechanical integrity and barrier properties. Through comprehensive laboratory testing, this study carried out a critical assessment of the mechanical and chemical properties of PET/PE flexible p…
FINDING: Penrose tilings are aperiodic and their tiling problem is computationally undecidable, equivalent to the halting problem. MATH: - Penrose tilings use two rhombi (angles 36°/144° and 72°/108°) with edge lengths in golden ratio φ = (1+√5)/2 ≈ 1.618. - Aperiodicity enforced by matching rules that forbid periodic…
The environmental durability under 720 h water immersion of recycled polymer composites is a key requirement for their application in humid service environments. This study investigates the influence of biochar on the moisture transport behaviour and mechanical durability of recycled polypropylene (rPP) composites fab…
Abstract Flexible polyimide (PI) dielectrics must simultaneously combine a dielectric constant (Dk) below 2.5, water uptake below 1 wt %, and sufficient mechanical strength, representing a persistent materials trilemma. Post-synthetic surface fluorination of porous fillers may leave internal polar sites insufficiently…
The increasing accumulation of polyethylene terephthalate (PET) bottles represents a significant environmental challenge due to their high consumption and limited recovery. The purpose of this study was to develop a sustainable alternative for reusing this waste by manufacturing educational test specimens for laborato…
Biochar is a porous carbonaceous material synthesized through the pyrolysis of diverse biomass resources, including agricultural and forestry residues as well as livestock manure. It possesses superior characteristics such as a large specific surface area, adjustable pore architecture, abundant surface functional grou…
This paper examines the theoretical and practical voltage limitations of aluminum–air batteries. It reviews the electrochemical reactions responsible for energy generation, including aluminum oxidation and oxygen reduction, and explains why the theoretical cell voltage of approximately 2.71 V is significantly higher t…
AIMS: Breast cancer (BC) remains the most prevalent malignancy in women, with conventional chemotherapy limited by drug resistance. This study develops a glutathione (GSH)-responsive nanoplatform combining chemotherapy with phototherapy against drug-resistant BC. METHODS: Gambogic acid (GA) was conjugated to carboxyme…
Atlantic bonito (Sarda sarda) is a commercially important fish species with high nutritional value that is widely harvested along the Portuguese coast; however, it is highly susceptible to lipid oxidation and microbial deterioration during refrigerated storage. This study investigated the effectiveness of oregano oil…
Abstract Supervised Machine Learningmodels are often regarded as black boxes, as they are frequently designed to give accurate predictions without disclosing how individual features contribute to those outcomes. Explainable Machine Learning (XML) offers methods such as feature importance and SHAP value analysis to mak…
The upscaling of waste-derived nanomaterials represents a critical intersection between nanotechnology and sustainable resource management. This chapter examines recent advances in converting diverse waste streams, such as agricultural residues, industrial by-products and electronic waste, into high-value nanomaterial…
This study presents biodegradable antibacterial biocomposite beads incorporating Calotropis procera powder within a hyaluronic acid–alginate matrix (HA/ALG/CPP) prepared via ionic crosslinking with calcium chloride. Beads with varying plant powder loadings (5–20 wt%) were fabricated and systematically characterized. S…
This study investigates the suitability of sunflower husks as an alternative raw material for the production of particleboards. For this purpose, shredded sunflower husks bonded with 5% polymeric diphenylmethane diisocyanate (pMDI) were used. Single-layer particleboards were manufactured at three density levels: 800,…
The bottom-up synthesis of life aims to replicate the characteristics of natural living systems from basic abiotic building blocks. In this context, synthetic cells based on liquid-liquid phase separation, such as complex coacervate droplets, have gained attention because they form spontaneously and readily take up mo…
Doğal karakterdeki bir tekstil malzemesinin özü itibariyle ekolojik olsa bile üretim sürecinde gördüğü ekolojik olmayan işlemler dolayısıyla sürdürülebilir olmayabileceği fikrinden yola çıkıldı. Doğal tekstil malzemelerinden yün, pamuk, keten ve kenevirin sürdürülebilirliğe uygunlukları ve sürdürebilirlik kapasitesi a…
FINDING: Icosahedral symmetry group is simple; quasicrystals exhibit non-Fermi liquid behavior; viral capsids use icosahedral symmetry for assembly. MATH: - Icosahedral rotational symmetry group: order 60, isomorphic to \(A_5\) (alternating group on 5 letters), simple (no nontrivial normal subgroups). - Quasicrystal p…
Epsilon-near-zero (ENZ) photonic media exhibit extreme optical dispersion that enables unconventional light–matter interactions and enhanced optical nonlinearities. Recent studies suggested that thermo-optic effects, traditionally regarded as slow and secondary, can be strongly modified under the ENZ condition. We est…
Abstract 4 H b -TaS 2 is a natural heterostructure of correlated ( T ) and superconducting ( H ) layers. Using time- and angle-resolved photoemission spectroscopy, we observe a narrow feature slightly above the Fermi level on the T -layer termination, corresponding to the band edge of a charge-density-wave (CDW)-gappe…
ABSTRACT Dynamic covalent assemblies offer ample structural and functional diversity, and dynamic bonding systems with tunable stability and controlled bond transformation are challenging to achieve due to the inherent conflict between the stability and the reversibility. Herein we report a photoswitching‐mediated C–N…
