“…The total waste of date palms is about 620,000 MT. Several attempts have been made to convert palm date biomass into valuable materials, such as activated carbon [21], hydrogel [22], biodiesel [23], and syngas [24]. However, most date palm wastes, such as leaves, twigs, and fibers, are not fully utilized in most cases and are usually burned, leading to numerous environmental problems (e.g., the unrestricted release of hazardous flue gas consisting of soot, CO 2 , NO x , SO x , etc.…”

In the present study, the ability for novel carbon microspheres (CMs) derived from date palm (Phoenix dactylifera) biomass using a hydrothermal carbonization (HTC) process and activated using phosphoric acid to remove methylene blue dye was investigated. Three types of palm-based wastes (seeds, leaflet, and inedible crystallized date palm molasses) were used and converted to CMs via the HTC process. The prepared samples were then activated using phosphoric acid via the incipient wetness impregnation method. The CMs samples before and after activation were analyzed using scanning electron microscopy (SEM), elemental analysis and scanning (CHNS), and the Fourier transform infrared (FTIR) and Brunauer–Emmet–Teller (BET) methods. The samples exhibited high BET surface areas after activation (1584 m2/g). The methylene blue adsorption results showed good fitting to the Langmuir, Fruendlich, and Temkin isotherm models for all activated samples. The maximum adsorption capacity achieved was 409.84 mg/g for activated CM obtained from the palm date molasses, indicating its high potential for application as a dye-based adsorption material.

“…Among all biomaterials, hydrogels have received extensive attention as scaffolds for cartilage tissue engineering due to their porous scaffolds and structural similarities to extracellular matrix (ECM) ( Van Vlierberghe et al, 2011 ). Hydrogels are hydrophilic three-dimensional structures composed of homopolymers and copolymers that can absorb water and swell in aqueous solutions, creating an appropriate microenvironment similar to ECM ( Kabiri et al, 2016 ; Sabzevari et al, 2016 ; Sabzevari and Kabiri, 2016 ). Therefore, it promotes the attachment, migration, differentiation, and proliferation of osteoblasts and chondrocytes and effectively delivers growth factors and nutrients ( Jin et al, 2009 ; Van Vlierberghe et al, 2011 ; Yazdimamaghani et al, 2014 ; Daly et al, 2020 ).…”

With the increase in weight and age of the population, the consumption of tobacco, inappropriate foods, and the reduction of sports activities in recent years, bone and joint diseases such as osteoarthritis (OA) have become more common in the world. From the past until now, various treatment strategies (e.g., microfracture treatment, Autologous Chondrocyte Implantation (ACI), and Mosaicplasty) have been investigated and studied for the prevention and treatment of this disease. However, these methods face problems such as being invasive, not fully repairing the tissue, and damaging the surrounding tissues. Tissue engineering, including cartilage tissue engineering, is one of the minimally invasive, innovative, and effective methods for the treatment and regeneration of damaged cartilage, which has attracted the attention of scientists in the fields of medicine and biomaterials engineering in the past several years. Hydrogels of different types with diverse properties have become desirable candidates for engineering and treating cartilage tissue. They can cover most of the shortcomings of other treatment methods and cause the least secondary damage to the patient. Besides using hydrogels as an ideal strategy, new drug delivery and treatment methods, such as targeted drug delivery and treatment through mechanical signaling, have been studied as interesting strategies. In this study, we review and discuss various types of hydrogels, biomaterials used for hydrogel manufacturing, cartilage-targeting drug delivery, and mechanosignaling as modern strategies for cartilage treatment.

“…It is well known from biomass waste practices and the literature that the structural (Fourier-transform infrared spectroscopy, Raman spectroscopy) [13,16,31,[34][35][36][37], morphologi-cal (X-ray diffraction, scanning electron microscopy, atomic force microscopy) [31,34,36,38,39], mechanical [40,41], and thermal characterizations (thermogravimetric analysis-TGA; differential scanning calorimetry-DSC; dynamic mechanical analysis-DMA) [31,35,37,40,[42][43][44][45] of these lignocellulosic compounds represent a key stage before addressing any application field. In this framework, a substantial body of research has been devoted to thermogravimetric analysis of biomass powders because it offers a deep understanding of the nature of pyrolysis phenomena and their kinetics.…”

Woody lignocellulosic biomasses comprise the non-edible parts of fruit trees. In recent years, the exploitation of this biomass has been widening in order to mitigate environmental issues. At the same time, this waste could be transformed into a value-added product (active carbon by pyrolysis, isolation of nanocellulose, oils or proteins). For either valorization path, a complete thermo-mechanical characterization is required. A detailed thermo-mechanical study (TGA, DSC, DMA) was performed on two types of lignocellulosic wastes, with and without kernels: on one side, the walnut shells (WS) and the pistachio shells (PsS) and, in the second category, the apricot seeds (AS), the date seeds (DS), and the plum seeds (PS). The results of the sample-controlled thermal analyses (HiRes TGA) evidenced a better resolution of the degradation steps of WS. Kinetic studies conducted also by conventional TGA (Flynn–Wall–Ozawa) and modulated TGA (MTGA) allowed us to make comparative reasonings concerning the degradation of the investigated biomasses. The DMA results revealed the effect of water traces and oil kernels on relaxation and supported the atypical DSC endotherm emphasized in the freezing temperature domain.
