The cold sintering process (CSP) has emerged as a revolutionary technique for low-temperature processing of ceramics and composites, enabling high-density fabrication at low temperatures. In this study, we demonstrated the implementation CSP in fabricating γ-glycine (γ-G)-bacterial cellulose (BC) composite evaluated effect temperature holding time on microstructure electrical properties. Our findings revealed that an increase leads to grain growth, transient solvent (water) facilitates...
Natural biopolymer materials have been of interest in wearable energy harvester technology, especially biocompatible triboelectric nanogenerators (BTENGs), due to their biodegradable, biocompatible, nontoxic and excellent antibacterial properties. Nevertheless, obstacles concerning economical utilization (TENGs) continue prevail. The natural biopolymer, chitosan (CS), is composed a long chain N-acetyl glucosamine. It enables exciting opportunities for low-cost, biodegradable nanogenerator...
Dielectric materials, like barium titanate-based (BT-based), have excellent dielectric properties but require high temperatures (above 1300 ˚C) for ceramic fabrication, leading to costs and energy loss. The cold sintering process (CSP) offers a solution these issues is gaining worldwide attention as an innovative fabrication route. In this work, we proposed alternative organic ferroelectric phase, gamma-glycine (γ-GC) that acts transient liquid phase fabricate high-density composites with...
In this work, double-layer mulch composite fi lm was prepared from natural materials (bacterial cellulose; BC, alginates, carboxymethyl CMC, and calcium hydrogen phosphate; CaHPO4) by the solvent casting method. The BC/CaHPO4 casted as a second layer serves two purposes: soil water absorption slow-release fertilizer. mechanical properties of double are signifi cantly improved using technique with tensile strength 17.4 MPa percentage elongation at break 78.7%. biodegradation increased to 60%...
This research aims to reduce production capital costs and added value natural products. The bio-mulching film was prepared by bacterial cellulose (BC) “Acetobacter xylinum”, extracted from three rotten fruits, grape, coconut, pineapple under standard tests in the laboratory. analysis FTIR technique confirmed molecular vibration of BC films. XRD pattern matched structure crystallinity JCPDS file which possessed a high percentage crystallinity. SEM micrographs were also revealed 3D nanofiber...
The purpose of this research was to enhance the surface linear low-density polyethylene (LLDPE) film by using single and hybrid nucleating agents reduce fat stains from food adherence on for easy rinsing before recycling, consequently reducing energy consumption recycling. process begins with preparation a high-concentration masterbatch LLDPE glycol (PEG), followed blown test analysis. results showed that both resulted in substantial modifications characteristics film. altered texture makes...
First, we explore the effect of bioacids on film processing preprocessed, i.e., deacetylated, chitosan (d-chitosan with molecular weight 1,000,000 kDa), using monocarboxylic acid (acetic acid), dicarboxylic (malic and tricarboxylic (citric acid) as model weak acidic solvents to destabilize hydrogen bonding transform crystal structures into film. Second, investigate chemical physical toughening in bionanocomposite composed cross-linkable multicarboxilic acid, succinic (SA). In doing so,...
This study presents a comprehensive exploration of enhancing the electrical output flexible hybrid piezoelectric-triboelectric nanogenerators (P-TENGs) through incorporation γ-glycine (γ-GC) into fully organic γ-GC/chitosan (CS) composites. A systematic investigation effects γ-GC content (wt%) on material characteristics and resulting signal is conducted. The research demonstrates pivotal role optimized CS concentrations in achieving superior performance. Through adherence to percolation...
