Newest firstUtilizing forestry and agricultural byproducts like wood and hemp residues advance sustainable additive manufacturing (AM), while reducing material costs. This study investigated the development and characterization of wood-sodium silicate composites incorporating hemp hurd and hemp fibers for AM applications. Formulations varied by wood fiber type (unsifted, 40 mesh, and pellet), sodium silicate concentration (50…
Open article record in new tab ↗Hemp is a high-yield crop traditionally cultivated for fiber used in products such as paper, textiles, ropes, and animal bedding, and more recently for sustainable applications in biofuels, insulation, and bioplastics. Beyond fiber, hemp is rich in phytochemicals. More than 500 compounds including cannabinoids, terpenes, phenolics, phytosterols, and tocopherols are accumulated in leaves, flowers, and seeds, which…
Open article record in new tab ↗Valorization of abundant agricultural residues, particularly lignin, provides the opportunity to divert waste streams while enabling materials to inherently exhibit durable functionalities, including UV-blocking, antioxidant properties and water repellency. This study reports the side-by-side valorization of hemp hurd (HL) and corn stover lignin (CL), extracted using the CELF process, into electrospun lignin/nylon…
Open article record in new tab ↗The rapid growth of the cannabidiol (CBD) market has raised concerns about product labeling accuracy and quality control. This study aimed to validate a high-performance thin-layer chromatography (HPTLC) method and apply it to analyze CBD content in commercial oils and e-liquids available in Costa Rica. The HPTLC method was validated following guidelines of the International Council for Harmonization of Technical…
Open article record in new tab ↗Hemp (Cannabis sativa L.) is one of the oldest cultivated plants in the world. It is a wind-pollinated and heterozygous species, and diverse phenotypes can occur within population varieties. In our study, three different hemp varieties-('Carmagnola Selected' (CS), 'Tiborszallasi' (TS) and 'Finola selection' (FS))-were grown. Based on visual characteristics, two, five and four phenotypes were identified within CS,…
Open article record in new tab ↗Plants frequently encounter diverse abiotic stresses, which require precise transcriptional regulation to maintain basic survival plasticity. The BES1 transcription factor family, a key component of brassinosteroid (BR) signaling, plays critical roles in plant development and stress responses. However, the genomic characterization, evolutionary characteristics, and biological functions of the BES1 family in indust…
Open article record in new tab ↗Plant lecithins are complex mixtures of phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), phosphatidic acid (PA) and lysophospholipids. They are increasingly demanded as natural, non-allergenic emulsifiers and as nutraceutical carriers. Quantitative data on the phospholipid (PL) fraction of less-commodity oilseeds, however, remain dispersed. This review compares the PL composition…
Open article record in new tab ↗The concept of the "cannabidiol (CBD) Hazard Triangle" reflects the unique position of CBD at the intersection of three overlapping dimensions: CBD as a substance associated with medicinal and pharmacological effects ("Drug"); CBD as a food ingredient subject to the EU Novel Food regulatory framework ("Novel Food"); and CBD as a potential source of food safety concerns ("Hazard"). This study investigates the growi…
Open article record in new tab ↗Cannabis sativa L. is a predominantly dioecious species, but sex expression is highly plastic and can be modified by genetic, hormonal, developmental, and environmental factors. This plasticity has major implications for commercial production because hermaphroditic expression in female plants can cause unintended pollination, seed formation, reduced floral quality, and losses in cannabinoid yield. This review summ…
Open article record in new tab ↗Introduction The study of hemp-based cannabinoids has focused primarily on cannabidiol (CBD). Cannabis sativa however, naturally synthesizes cannabidiolic acid (CBDA) as opposed to the better-known neutral derivative. The precursor to cannabidiolic CBDA is cannabigerolic acid (CBGA) and cultivar extracts that contain both acidic cannabinoids are available as animal supplements. Pharmacokinetically these acidic can…
Open article record in new tab ↗The urban heat island effect is strongly linked to the use of dense mineral pavements with high thermal inertia and lacking passive heat dissipation mechanisms. This article evaluates the potential of evaporatively cooled concrete pavers, based on capillary action and evaporation by incorporating recycled, bio-based, and lightweight materials to develop functional porosity. Ten paver formulations were developed us…
Open article record in new tab ↗Hemp (Cannabis sativa L.) is a multipurpose crop with significant industrial and therapeutic potential. This article reviews the various uses of hemp in production, building, food, cosmetics and medicine, focusing on its economic, environmental and health benefits. Industrially, hemp has been used for making fabrics, paper, bioplastics, construction materials and biofuels, because of its strong fibres, fast growth…
Open article record in new tab ↗This dataset provides Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectra of Cannabis sativa L. leaves from five industrial hemp varieties cultivated under field conditions in Paraguay. In total, the dataset comprises 80 ATR-FTIR spectra, corresponding to five varieties, two treatment conditions, and eight biological replicates per combination. The dataset includes raw spectral profiles from…
Open article record in new tab ↗Genomic characterization of Cannabis sativa has accelerated rapidly in the last decade as sequencing costs have decreased and public and private interest in the species has increased. Here, we present seven new chromosome-level haplotype-phased genomes of C. sativa. All of these genotypes were alive at the time of publication, and several have numerous years of associated phenotype data. We performed a k-mer-based…
Postharvest operations affect the yield and quality of industrial hemp (Cannabis sativa L.). This study aimed to investigate the postharvest drying and curing effects on the key quality and safety indicators of cannabinoid-type hemp. Freshly harvested hemp inflorescence of Hempress and Wild Bourbon cultivars were dried by three methods: (1) Hot air drying at 75 °C; (2) Ambient air drying at 25 °C; and (3) Freeze d…
Open article record in new tab ↗Cannabis sativa is a mainly dioecious plant, which means that female and male flowers develop on separate individuals, which is controlled by an XY sex determination system: females have two X chromosomes and male plants carry an X and a Y chromosome. C. sativa is a crop that has a wide variety of applications, some of which depend on the sex of the plant. Females are, for example, used for the cannabinoid product…
Open article record in new tab ↗Hemp field retting is a bioprocess that facilitates fibre extraction by degrading pectin and other matrix components surrounding fibre bundles. However, traditional methods rely on empirical practices, often resulting in inconsistent fibre quality. This study investigates the biodiversity-function relationship in the hemp retting ecosystem to identify microbial and enzymatic indicators for improved process control…
This study evaluates the thermal conductivity of hemp-based insulation materials, focusing on loose bulk mixtures of hemp fibre and hurd. Transient Plane Source (TPS) measurements were employed to assess the thermal conductivity of these materials, with a controlled variation in the fibre-to-hurd ratio and bulk density. Samples from various suppliers, including those with different fibre diameters and hurd content…
Open article record in new tab ↗Cannabis sativa L. containing < 0.3% delta-9 tetrahydrocannabinol (THC) is currently defined as hemp. Many different legal products in the United States now contain hemp and are marketed for their cannabinoid effects, as an alternative to tobacco products, or even as an aid for tobacco smoking cessation. The hemp cigarettes analyzed have similar designs to tobacco cigarettes with a filter and filler wrapped in pap…
