Summary: A strong and water-stable lignin-cellulose composite (LCC) was developed using nanocellulose hybrid lignin complex (CHLC), significantly increasing the dry strength and wet strength compared to a typical lignin-free cellulose sheet. The LCC is an eco-friendly and biodegradable alternative to plastic, providing a solution for the mechanical properties' degradation and uncontrolled deformation challenges in cellulose as a replacement for plastic.

Summary: This study prepared LCNFs with lignin content ranging from 4.69% to 17.53% by adjusting the concentration of p-TsOH and hydrolysis temperature. It was found that the physical and chemical properties of LCNFs were significantly affected by the lignin content, with an increase leading to higher diameters and water contact angles, and lower crystallinity. Furthermore, by-product lignin nanoparticles (LNPs) with an average diameter of 50-500 nm were generated, enhancing the resource utilization value of SBP.

Summary: Hydrothermal liquefaction is a promising technology for converting high moisture biomass into biofuels. Research shows that lignin extracted from the process of lignocellulosic ethanol production can produce higher amounts of bio-oil compared to commercial cellulose. Dehydration is the main reaction observed for both raw materials, but decarboxylation plays a more important role in lignin liquefaction.

Summary: This study investigates the interactions between cellulose and lignin during fast pyrolysis at temperatures of 100-350 degrees C. The results suggest that co-pyrolysis of cellulose and lignin enhances volatile release at lower temperatures but increases char formation at higher temperatures. The differences in char yields between experimental and calculated values provide evidence of cellulose-lignin interactions during co-pyrolysis.

Summary: To address the urgent issue of freshwater pollution and shortage, a multi-functional membrane for fresh water production was developed. The regenerated lignocellulose modified cotton fabric showed excellent properties for efficient oil-water separation and solar steam generation. The membrane had underwater superoleophobic property, high evaporation rate, and salt-resistance, while being naturally degradable and environmentally friendly. This green and efficient membrane has great potential in oil-water separation and sewage purification.

Summary: The structural reconstruction mechanism of lignin and cellulose-derived biochars during direct graphitization under ultra-high temperatures was investigated. It was found that lignin-derived char retained some of its skeleton structures, while cellulose-derived char was composed mainly of carbon microcrystallites. This structural difference played a vital role in the formation of graphitic layers. The study provides theoretical guidance for preparing high-performance carbon materials from lignocellulosic biomass.

Summary: This study evaluated the influence of untreated and surface-modified nanofibrillated cellulose (NFC) on composite PLA matrix filaments, finding that the addition of NFC slightly affected the filaments' properties. The unmodified and surface-modified NFCs were present in the form of plate-shaped agglomerates.

Summary: Lignin-containing cellulose nanofibrils (LCNFs) with tunable lignin contents were directly prepared from sugarcane bagasse. LCNFs showed a more uniform size and narrow diameter distribution compared to cellulose nanofibrils (CNFs). CNPs made from LCNFs exhibited outstanding mechanical and optical properties, and LCNFs had higher water contact angles than CNFs.

Summary: Comparative studies on C3 and CAM succulents in a desert region of South Africa found that under identical conditions, C3 plants had higher carbon gain compared to CAM plants, while their maximum photosynthetic activity was similar. The differences in response dynamics to irrigation were attributed to variations in rooting depth, morphology, and water acquisition strategy between the two plant types.

Summary: Chlorophyll a fluorescence analysis is commonly used to study postharvest activity and stability of photosynthesis in vegetables and fruits. Commercial chlorophyll fluorescence imaging systems provide additional insights into spatial and temporal dynamics of photosynthesis, offering valuable information on the effects of postharvest handling and processing on the internal quality of green produce. While the physiological basics of fluorescence parameters are briefly summarized, the focus is mainly on recent applications of chlorophyll fluorescence imaging for evaluating quality and quality maintenance during postharvest handling and minimal processing of fresh fruits and vegetables.

Summary: The study investigated the fruit-bearing capacity (FBC) of apple trees through considering the inter-tree variability of leaf area. It was found that the variance of FBC was similar in two years, but each individual tree showed different FBC in both seasons, with FBC ranging from 84 to 179 fruit per tree depending on the total leaf area of the trees. The study also found that fruit quality, indicated by size and soluble solids content, showed enhanced percentages according to the seasonally total absorbed photosynthetic energy.

Summary: Green-ripe banana fruit are sensitive to chilling injury and early detection of chilling effects on photosynthesis is crucial for quality maintenance. Optical techniques such as chlorophyll a fluorescence analysis and spectroscopy can be promising tools, but a rigorous evaluation of chilling impacts on photosynthesis is necessary.Continuous and modulated CFA, imaging, and VIS remission spectroscopy can comprehensively reflect various effects of chilling on fruit photosynthesis, providing relevant requisites for improving CI monitoring and prediction.

Summary: Research shows that controlled mild water deficits during radish growth can positively affect the overall performance of produce and potentially improve their shelf life. However, it does not significantly impact photosynthesis and tuber yield. Limited water availability results in slightly reduced tuber water content and water potential, but increased sugar content and proline concentration.
