Summary: With the increase of discarded electronic devices, gold recovery from e-waste has become a topic of great interest. Covalent organic framework (COF), a new kind of porous crystalline material, shows advantages in gold recovery due to its large specific surface area, selective functional groups, regular channels, and controllable synthesis. In this study, a simple structured and highly crystalline COF decorated with abundant hydroxyl groups (TzDa-COF) was prepared and demonstrated to have high selectivity and fast kinetics in gold recovery.

Summary: This study evaluated the effects of adding agro-industrial lignocellulosic wastes to particleboards made with eucalypt wood. While the mechanical properties of these particleboards were generally inferior to the control group, the addition of 10% of the waste was found to meet the requirements for particleboards of general use. The environmental gains of using these wastes are promising as it helps avoid inappropriate disposal.

Summary: This study utilized waste paper as a cross-linking agent to immobilize persimmon tannin for the removal of U(VI) and Cr(VI), achieving competitive maximum removal capacities. The adsorption process was influenced by various factors and well fitted by Langmuir and Pseudo-second-order equations. Adsorption mechanisms were identified as surface complexation for U(VI) and redox reaction for Cr(VI), providing a high-efficiency and low-cost adsorbent for radioactive nuclide and heavy metal treatment.

Summary: This study found that L-arginine treatment during low-temperature storage of persimmon can reduce weight loss and chilling injury, maintain fruit firmness and antioxidant enzyme activity, and increase the content of total soluble tannin compounds. However, it has no significant impact on titratable acidity and total soluble solids. Therefore, the application of L-arginine can effectively improve the postharvest quality and extend the storage life of persimmon.

Summary: MdPG1 encoding polygalacturonase is a key gene related to fruit firmness and texture variations in apple. We identified a SNPA/C variant in the promoter region of MdPG1 and found that the promoter with SNPA could be strongly bound and activated by MdCBF2, while the promoter with SNPC could not. We also discovered a novel long non-coding RNA, lncRNA(PG1), in the promoter of MdPG1, which was a causative variant. Our study provides new insights into the genetic regulation of MdPG1 allele expression and has implications for apple breeding.

Summary: MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression at the posttranscriptional level by negatively modulating target mRNA expression through translational inhibition or degradation. The study focuses on the regulatory role of miRNAs in fruit crops, exploring their biosynthesis, target genes, function, and regulatory network, and providing a theoretical basis for future research on miRNAs in fruit plants.

Summary: By studying the key flowering-time gene FLC in precocious walnuts, it was found that FLC was specifically expressed during the bud dormancy stage of precocious walnut and its expression gradually decreased as the ambient temperature warmed. Overexpression of JrFLC in Arabidopsis thaliana delayed flowering and increased the total leaf number, suggesting that JrFLC also functions as a floral repressor in walnut and other plants.

Summary: Ethylene production is negatively associated with storage life in sand pear, and 1-aminocyclopropane-1-carboxylic acid synthase (ACS) is considered crucial for fruit storage. The study identified 13 ACS genes in the sand pear genome, showing different expressions in climacteric and non-climacteric fruit types during ripening. These ACS genes have different roles in ethylene biosynthesis during fruit development, associated with system 1 and system 2 of ethylene production.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
