“…It is estimated that there will be over 40 million date palm trees in the UAE. 31 Hence, an enormous amount of lignocellulosic biomass waste material is available in the form of leaves, fibers, date pits/stones, and stem waste. 32 Furthermore, it contains a plentiful amount of cellulose (30–45%), which is an advantage to isolate good yields of CNCs.…”

This study presents the isolation, characterization, and kinetic analyses of cellulose nanocrystals (CNCs) from date palm waste in the United Arab Emirates. After bleaching date palm stem waste with acidified NaClO 2 and delignification via NaOH treatments, cellulose was extracted. Mineral acid hydrolysis (62 wt % H 2 SO 4 ) was performed at 45 °C for 45 min to produce crystalline nanocellulose. Fourier transform infrared (FTIR) and chemical composition analysis confirmed the removal of noncellulosic constituents. The crystallinity index increased gradually with chemical treatments, according to the obtained X-ray diffraction (XRD) results. Thermogravimetric analysis and differential scanning calorimetry results revealed that the CNC has high thermal stability. The Coats–Redfern method was used to determine the kinetic parameters. The kinetic analysis confirmed that CNC has more activation energy than cellulose and thus confirms its compact and resistive crystalline structure. This has been attributable to the stronger hydrogen bonding in CNC crystalline domains than that in cellulose crystalline domains. Scanning electron microscopy revealed that lignin and hemicellulose were eliminated after chemical pretreatments, and CNC with a rodlike shape was obtained after hydrolysis. Moreover, transmission electron microscopy confirmed the nanoscale of crystalline cellulose. ζ potential analysis indicated that the CNC afforded a stable suspension (−29.27 mV), which is less prone to flocculation. Kinetic analyses of cellulose and cellulose nanocrystals isolated from date palm waste are useful for making composites and designing selective pyrolysis reactors.

“…Studies of ocular injuries due to date palm thorns and prickly pear spine showed mostly these thorny fruits causing keratitis, corneal ulcer, and corneal perforation with no injury beyond the lens. Both studies also show that eye injuries occur mainly due to a lack of protective eyewear [ 6 , 7 ]. Our patient demonstrated severe ocular injury caused by durian.…”

A devastating ocular injury can be caused by durian, the "king of fruits." We report a case of open globe injury secondary to a durian fruit fall. A 54-year-old unfortunate male was accidentally hit by a durian fruit that fell from a tree. The fruit hit directly his right face and eye. He experienced a transient loss of consciousness. He sustained extensive corneal and multiple scleral lacerations with total hyphema, iridodialysis, posterior dislocation of the lens, and retinal detachment. There were also multiple sites of a puncture wound on the right side of the face and right upper lid laceration. Primary suturing of corneal and scleral laceration with anterior chamber washout was performed. The right visual acuity remained poor postoperatively. Durian fruit injury to the eye may lead to severe devastating ocular complications that lead to blindness. The prognosis depends on the severity of the injury.

“…The date palm (Phoenix dactylifera) is a flowering plant cultivated principally for eating its fruit. Date trees can reach lengths of 21 to 23 m, with leaves that can attain heights of 4 to 6 m and have about 150 leaflets each [1]. The trees typically grow individually or in clusters from a single root system.…”

Dates are the fruits of the date palm belonging to the Arecaceae family; they comprise over 2500 species and 200 genera and constitute an essential part of the daily diet worldwide, with beneficial nutritional, health, and economic values. Several varieties of date palm (Phoenix dactylifera) fruit exist globally, especially in hot and humid regions. This review is an overview of date palms as a significant global food resource, including their historical significance, nutritional composition, cultivation practices, economic importance, and health benefits. The historical journey of dates goes back to ancient civilizations where they were revered for their richness in essential nutrients and natural sweetness. Today, dates are a vital crop in arid regions, contributing substantially to the agricultural economy and livelihoods of communities. This paper further explores the cultivation techniques employed to enhance date production. Furthermore, the nutritional composition of dates is analyzed in detail, highlighting their high content of vitamins, minerals, dietary fibers, and antioxidants. These attributes make dates a delicious treat and a valuable nutritional component, offering numerous health benefits. The potential health effects, including improved digestion, enhanced cardiovascular health, and increased energy levels, are discussed. Additionally, this paper delves into the economic significance of the date industry and its global trade.
