In modern engineering applications, the use of sustainable materials and eco-friendly methods has become increasingly important. Wood joints, especially those strengthened with bio-adhesive, have attracted considerable attention due to their inherent environmental benefits desirable mechanical properties. Compared traditional joining methods, adhesive joints offer unique advantages such as improved load distribution, reduced stress concentration, enhanced aesthetic appeal. This study aims enhance delamination resistance in wooden using a novel method involving reinforced high-toughness resin on surfaces. Additionally, hybrid substrate approach applies tough layer outer plies densified wood core greater fiber direction strength. Normal, toughened, single-lap joint specimens were analyzed through both experimental numerical under various loading conditions, including quasi-static intermediate rates. The proposed involved bio-adhesive penetration into substrate, forming surface zone. experimentally validated results show significant improvement strength, exhibiting an approximate 2.8-fold increase for toughened compared reference intermediate-rate conditions. Furthermore, absorbed energy increased by substantial factor up 4.5 times same fracture surfaces analysis revealed that toughening changed failure mechanism from breakage, indicating strength was lower than impact viscoelastic behavior also influenced response changing displacement rate. resilience load-bearing capacity making them more suitable dynamic applications.

Celluloid, the predecessor to plastic, was synthesized in 1869, and due technological advancements, plastic products appear be ubiquitous daily life. The massive production, rampant usage, inadequate disposal of have led severe environmental pollution. Consequently, reducing employment has emerged as a pressing concern for governments globally. This review explores microplastics, including their origins, absorption, harmful effects on environment humans. Several methods exist breaking down plastics, thermal, mechanical, light, catalytic, biological processes. Despite these methods, microplastics (MPs, between 1 5 mm size) continue produced during degradation. Acknowledging significant threat that MPs pose human health is imperative. form pollution pervasive air food infiltrates our bodies through ingestion, inhalation, or skin contact. It essential assess potential hazards can introduce. There evidence suggesting may negative impacts different areas health. These include respiratory, gastrointestinal, immune, nervous, reproductive systems, liver organs, skin, even placenta placental barrier. encouraging see most countries taken steps regulate particles. measures aim reduce which today. At same time, this summarizes degradation mechanism impact health, reduction policies worldwide. provides valuable information future research regulatory development.

Biomimetics has revolutionized materials innovation by drawing inspiration from biological systems. Cellulosic paper, a sustainable biomaterial, offers immense potential for biomimetic research. Paper-based materials, which replicate the structures and functionalities of natural utilizing cellulosic fiber network as substrate or skeleton, provide customizable functional properties, thereby enabling advanced applications. Here, we introduce rice-leaf-mimetic inspired leaf's microstructure biowax-based cuticle. This paper exhibited self-cleaning superhydrophobicity showcased possibilities additional functionalities, including antibacterial properties food preservation. We herein propose its utilization rewritable biolubricant-infused surfaces. These somehow distinct surfaces draw chemistry rice leaf. Although incorporating hydrochromic dyes enables rewritability, controlling retention time colors remains challenging. The biowaxy structure prolongs color maintenance inhibiting water evaporation. Moreover, hierarchically rough effectively stores biolubricant molecules, reducing friction enhancing slipperiness. Surface microcavity ratio analysis provides insights into paper's lubricant-storability. surface engineering using biolubricants holds designing novel materials. Leveraging mass-producibility papermaking processes, in conjunction with broad concepts biomimetics engineering, expands innovation.
