Summary: This article introduces the traditional and modern applications of camphor, including its use as a source of wood, camphor, and perfume, as well as its use in treating inflammation and pain. However, there is currently a lack of systematic studies on the extraction and separation of camphor, as well as the medicinal effects of its various components.

Summary: In this study, we proposed an efficient pad dyeing method for wool fabrics using curcumin, which showed excellent dyeing performance. By wet steaming with added tannin, the utilization rate of natural dyes was significantly improved. This method endowed wool fabrics with excellent color intensity, fastness and antibacterial activity, while reducing energy consumption.

Summary: Isoprenoids, such as camphor released by Cinnamomum camphora, protect plant membranes against high temperature damage by maintaining membrane lipid stabilization. This study investigated the effects of camphor fumigation on membrane permeability, cell ultrastructure, membrane lipid variations, and gene expression in C. camphora under high temperature conditions. The results suggest that camphor acts as a signaling molecule and regulates the expression of genes related to lipid metabolism, thereby protecting the membrane system.

Summary: In this paper, the focus was on Cinnamomum camphora (L.) J. Presl. (Lauraceae) at three levels: micromorphological, phytochemical, and bioactive. The micromorphological investigation revealed the presence of secretory cells producing muco-polysaccharides and terpenes. Phytochemical analyses showed a predominance of monoterpenes, with 1,8-cineole, alpha-terpineol, and sabinene being the main components. Conservation procedures influenced the amounts of specific components in the essential oils, while antibacterial studies demonstrated promising activity against various microorganisms.

Summary: The study utilized natural dyes of madder and weld, native to Iran, with oak as a new tannin-rich mordant for dyeing yarns. The extraction method involved ultrasound-microwave assistance, yielding approximately 27%, 32%, and 36% for madder, weld, and oak respectively. Analysis included UV-Visible and SEM techniques, as well as assessment of fastness properties and colorimetric characteristics of the dyed yarns.

Summary: The efficiency of zeolite 4A and activated carbon (AC) in removing color, COD, TOC, and metals from wool dyeing wastewaters was evaluated in this study. The results showed that zeolite was effective in removing metallic ions, while AC was more efficient in reducing organic pollution. All three adsorbents significantly reduced the color of the wastewaters.

Summary: This study identified the chirality of borneol and camphor in C. camphora leaves and discovered an efficient BDH, CcBDH3, that catalyzes the conversion of borneol to camphor. Comparing with other reported BDHs, CcBDH3 showed high conversion rates with both (+)-borneol and (-)-borneol, providing a potential approach for producing new types of camphor.

Summary: A detailed characterization of the chemical composition and nutritional value of C. camphora seed kernels collected from different regions in China is provided. The results showed significant differences among the samples in weights, proximate composition, minerals, phenolics, flavonoids, and amino acid contents. The CCSKs may be developed as an excellent source of plant-based medium-chain oil, protein, dietary fiber, minerals, phytochemicals, and essential amino acids.

Summary: Due to the high demand for natural dyes, researchers have been using the microwave-assisted extraction (MAE) technique to extract natural dyes from plants. In this study, dyes were extracted from Quercus Coccifera L. species using a domestic microwave oven, and the extraction parameters of pH, microwave power, and extraction duration were studied. The quality of the dyeing was evaluated using colorimetric coordinates and colour strength.

Summary: Plant root and shoot growth are closely related, and their directional distribution of mass in architecture and resulting interactions are key to understanding the dynamic balance of below- and above-ground organs. This study focused on camphor trees and found opposite interactions between below- and above-ground biomass distributions. These findings enrich our understanding of root-shoot interactions and have implications for root design in urban forest management.

Summary: A comparative study was conducted on seven plant extracts applied on cotton fabric for coloration, mosquito repellency, UV protection, and antimicrobial potential. Tagetes erecta showed good mosquito repellency, UV protection, and antimicrobial potential but poor fastness, while Acacia nilotica demonstrated outstanding fastness properties but moderate color strength.

Summary: This study focused on the photocatalytic degradation of Rhodamine B in both heterogeneous and homogeneous photo Fenton reactions. Iron(II) doped copper ferrite nanoparticles were used as catalysts in the heterogeneous system, while H2O2 was employed for visible light-induced photodegradation in the absence of heterogeneous photocatalysts. Antibacterial tests showed inhibition activities of more than 60% against Vibrio fischeri.

Summary: This study investigates the effects of calcination temperature on the structural, morphological, and photocatalytic properties of CuII 0.4FeII 0.6FeIII 2 O4 ferrite. The ferrite was prepared using a simple precipitation method and subjected to sequential increments in calcination temperature. XRD and SEM analysis revealed the formation of separated phases of hematite and tenorite as the calcination temperature increased. The materials exhibited needle-like morphologies above 300 degrees C. Photocatalytic degradation of methylene blue followed pseudo-first-order kinetics.

Summary: The study establishes a sustainable method for fabricating microcapsules from Eucalyptus oil, Moringa oleifera, and Arabic gum. The microcapsules can be used to coat military clothing for mosquito repellency in mountainous and wilderness environments. The coated fabric demonstrates good mosquito-repellent properties and durability, but slightly affects the water absorbency and air permeability of the fabric.
