“…In fact, the process operates with the same basic catalysts described in the production of biodiesel, such as KOH, sodium methylate, sodium hydride, some amines, as well as different alkaline solids, operating as heterogeneous base catalysts at different experimental conditions [196][197][198][199][200][201][202][203][204][205][206][207][208][209][210][211][212][213][214]. Given the interest of the process, supercritical conditions [215][216][217][218][219][220][221][222] or the use of different lipases [223][224][225][226][227][228][229][230][231][232][233][234][235][236][237][238][239] have also been studied. DMC has been recently investigated in regards to the synthesis of fatty acid methyl esters via ionic liquids [240,…”

The delay in the energy transition, focused in the replacement of fossil diesel with biodiesel, is mainly caused by the need of reducing the costs associated to the transesterification reaction of vegetable oils with methanol. This reaction, on an industrial scale, presents several problems associated with the glycerol generated during the process. The costs to eliminate this glycerol have to be added to the implicit cost of using seed oil as raw material. Recently, several alternative methods to convert vegetable oils into high quality diesel fuels, which avoid the glycerol generation, are being under development, such as Gliperol, DMC-Biod, or Ecodiesel. Besides, there are renewable diesel fuels known as “green diesel”, obtained by several catalytic processes (cracking or pyrolysis, hydrodeoxygenation and hydrotreating) of vegetable oils and which exhibit a lot of similarities with fossil fuels. Likewise, it has also been addressed as a novel strategy, the use of straight vegetable oils in blends with various plant-based sources such as alcohols, vegetable oils, and several organic compounds that are renewable and biodegradable. These plant-based sources are capable of achieving the effective reduction of the viscosity of the blends, allowing their use in combustion ignition engines. The aim of this review is to evaluate the real possibilities that conventional biodiesel has in order to success as the main biofuel for the energy transition, as well as the use of alternative biofuels that can take part in the energy transition in a successful way.

“…Transferring valuable traits from generation to generation and studying the nature of heredity serve as the basis for producing new cotton cultivars resistant to various stress conditions. Accordingly, the determination and transmission of farm-valuable traits of subspecies of cultivated cotton (G. arboreum L.) diploids, generation to generation, and the nature of heredity have a greater scientific and practical importance in creating valuable and high fiber-yielding recombinants with good fiber quality, drought-resistant and early maturing based on hybridization (Rizaeva et al, , 2015Panchal et al, 2018). Increasing efficiency in cotton selection depends on the characteristics of the cultivars being created.…”

The present study, comprising an evaluation of cotton amphidiploid hybrids and their families for yield and fiber quality traits, commenced from 2007 to 2022 at the Chirchik State Pedagogical University, Tashkent, Uzbekistan. The amphidiploid hybrids’ creation was through interspecific hybridization of Gossypium hirsutum subsp. euhirsutum cultivar Kelajak × F1 (G. arboreum subsp. perenne × G. arboreum subsp. obtusifolium var. indicum) and experimental polyploidy, with genetically enriched new genotypes obtained. According to genetic variability, a considerable variation showed based on F1–F6 populations belonging to various clusters for the traits boll weight (2.3–6.21 g), 1000-seed weight (67.3–125.529 g), fiber length (24.9–34.4125 mm), fiber yield (31.4%–40.26%), and fiber index (6.3–7.5875 g). Furthermore, among the F6 G. hirsutum subsp. euhirsutum cultivar Kelajak × F1 (G. arboreum subsp. perenne × G. arboreum subsp. obtusifolium var. indicum) combination families, the promising genotypes selected gave the highest trait values for boll weight (6.6 ± 0.13 g – Family- 41), 1000-seed weight (125.8 ± 3.48 g – Family-59), fiber yield (40.3% ± 0.65% – Family-59), fiber index (8.5 ± 0.23 g – Family-59), and fiber length (34.5 ± 0.16 mm – Family-8). Genotype evaluation using cluster analysis allows the prediction of cotton families with a better combination of traits. Introgressive hybrids created based on the early maturing families, viz., Family-5, Family-8, Family- 13, Family-14, Family-41, and Family-59, with high yields and fiber indices attained inclusion in the Cotton Gene Pool, Uzbekistan (Certificate of the Academy of Sciences of the Republic of Uzbekistan No. 4/1255-2635 dated November 26, 2020). The promising families selected based on their best performance included F5 (G. hirsutum L. × F1 [G. arboreum L. × G. arboreum L.], Family-5, Family-8, Family-13, Family-14, and Family-59) and F6 (G. hirsutum L. × F1 [G. arboreum L. × G. arboreum L.], Family-5, Family-13, and Family-59), with the said cotton gene pool as valuable recombinants benefiting future breeding programs.
