From Pineapple Crown Waste to Functional Cellulose and Carboxymethylcellulose: Processing–Structure–Function Relationships for Circular Biorefinery Applications

Pineapple crown waste is a cellulose-rich residue generated along fresh-fruit and processing chains and is increasingly investigated as a feedstock for higher-value cellulosic materials. This review critically examines conversion of pineapple crown and related residues into cellu...

Forest Fragment Proximity as an Important Predictor of Restoration Success in Mining‐Degraded Areas

ABSTRACT Ecological restoration is essential for achieving global climate and biodiversity targets, particularly in tropical landscapes affected by large‐scale disturbances. Following the 2015 Fundão tailings dam collapse in Mariana, Brazil, extensive areas of the Atlantic Forest...

Experimental assessment of column rectangularity in flat‐slab slab–column connections

Abstract This paper presents an experimental investigation of the punching shear behavior of seven 3.00 m × 3.00 m × 0.20 m flat slabs without shear reinforcement, supported by internal rectangular columns. The column side lengths were varied to obtain aspect ratios, c max / c mi...

Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance, viscoelastic response, and residual stress distribution in fiber–metal laminates (FMLs). Two groups of laminates were produced: (i) fiber‐reinforced po...

Data and channel-aware device selection for split learning in resource-constrained B5G/6 G networks

Abstract Split learning (SL) is a promising distributed learning approach for fifth-generation/sixth-generation (B5G/6 G) networks. However, its performance is affected by bandwidth constraints and statistical heterogeneity in the data. Prior works have considered either channel-...

Landscape history matters: decoupled responses of plant taxonomic, phylogenetic and functional diversity to intensive agriculture impacts in Cerrado

Loss of woody plants due to intensive agricultural expansion is particularly critical because of their role in ecosystem functions and services, as well as in ecosystem resilience. Therefore, understanding the effects of landscape changes on multiple dimensions of biodiversity (i...

Pilot-scale optimization of atmospheric acid leaching for enhanced nickel and cobalt recovery from laterite ore

Nickel and cobalt are critical metals predominantly extracted from laterites. However, deposits with high iron content (>15%) and SiO2/CaO + MgO ratios (∼1.8) limit the applicability of conventional pyrometallurgical routes. In this scenario, hydrometallurgical processes, particu...
