This study developed an integrated process combining ultrasound-assisted enzymatic extraction (UAEE) with purification for the efficient recovery of bioactive flavonoids from Rhododendron anthopogonoides Maxim. (RA). Extraction conditions were optimi...
Antibody–drug conjugates (ADCs) are structurally complex biopharmaceuticals whose quantitative characterization is often complicated by payload-related interferences and molecular heterogeneity. In this study, two complementary chromatographic...
Germanium is a strategically critical metal with indispensable applications in infrared optics, fiber-optic communications, and semiconductor devices. Although previous reviews have extensively addressed the hydrometallurgical recovery of germanium f...
The global energy transition and rapid electrification are driving increased demand for copper. However, conventional pyrometallurgical and hydrometallurgical extraction routes are increasingly challenged by declining ore grades and stricter environm...
A new efficient coupled process to produce green solvent ethyl propionate was developed, which involved a fixed-bed reactor and pervaporation membrane separation. Firstly, the esterification reaction alone was investigated to explore reaction conditi...
Reversed-phase chromatography stationary phases (such as C18) are widely used in commercial high-performance liquid chromatography (HPLC). However, when dealing with complex mixtures, they often exhibit limited separation capabilities and peak tailin...
Excessive nitrate discharge causes water eutrophication and public health risks, which has become a core challenge in global water environment governance. Conventional nitrogen removal technologies suffer from limitations such as carbon source depend...
Photocatalytic degradation technology has been widely acknowledged for its low cost and high degradation efficiency. However, the loss, migration and difficult recovery of powdered catalysts are still critical bottlenecks for practical applications....
Gas–solid fluidized bed separation uses upward gas flow to fluidize a dense medium. By controlling medium properties, gas velocity, and bed height, the apparent bed density can be adjusted so that low-density particles float and high-density pa...
Extracellular polymeric substances (EPS) are recoverable high-value biopolymers from excess sludge (ES), but their antioxidant performance and enhancement strategies remain poorly understood. This study systematically investigated sludge-derived EPS...
Heavy metal wastewater, characterized by high toxicity, poor biodegradability, and strong bioaccumulation potential, poses a serious threat to the ecological environment and human health. Conventional chemical treatment methods are costly and prone t...
Separation sciences in Türkiye have evolved from early laboratory-based instruction into a robust, multidisciplinary field integral to analytical chemistry. The foundational roots were established before the Ottoman period and were further stren...
After in situ leaching of weathered crust elution-deposited rare earth ore (WREO), large amounts of residual ammonium (RA) salts remain in the ore body and slowly release, causing persistent ammonia-nitrogen pollution in surrounding waters. This stud...
Black cumin (Nigella sativa L.) oil is one of the most important vegetable oils with food, therapeutic and medicinal uses; however, it has high acid and peroxide values even in fresh oil extracted by cold pressing. One of the main factors that can ca...
Low-cost and effective F− removal technology and operational parameters were provided. A novel bimetallic fluoride-removing coagulant (BFrC) was synthesized. Simultaneous removal of fluoride (F−) and turbidity were studied using a new int...
Capillary electrophoresis (CE) is widely used for DNA fragment analysis, but its separation performance depends strongly on the composition of the polymer sieving matrix, especially in multicapillary systems where matrix operability and reproducibili...
Sludge-conditioning strategies are commonly optimized for filtration performance, with less attention paid to the rheological and textural properties of concentrated sludge and their relevance to low-temperature drying. Here, thermally modified drink...
The booming clean energy industry has driven the expansion of photovoltaic (PV) and lithium-ion battery (LIB) sectors, causing the accumulation of new energy solid wastes such as wind turbine blades (WTB), PV modules and LIBs. Such solid wastes exhib...
The compositional complexity of plant-derived food matrices and the structural diversity of phenolic compounds influence sample preparation, promoting miniaturized solid-phase extraction using advanced sorbents for their determination. This critical...
Hydrodesulfurization (HDS) is a critical technology for producing clean petroleum products. With the steady growth in annual crude oil processing volumes, the consumption of HDS catalysts has been continuously increasing. The massive release of spent...
Natural bioactive compounds found in plants, agri-food by-products, microorganisms, marine sources, and other sustainable biological resources continue to drive scientific innovation due to their structural diversity and wide spectrum of biological a...
This study developed an analytical method based on comprehensive two-dimensional gas chromatography–mass spectrometry/flame ionization detection (GC×GC-MS/FID) for the simultaneous qualitative and quantitative analysis of phenolic compoun...
Wastewater from textile industries that contain methylene blue poses a serious environmental problem due to its stability and toxicity. In the current study, calf starter feed (CSF), goat feed (GF), and lamb grower feed (LGF) were investigated as pot...
This study optimized supercritical fluid extraction (SC-CO2) parameters for Boswellia sacra leaves to evaluate how extraction thermodynamics influence subsequent pharmacological bioactivity. Using a multi-parametric approach, extracts obtained at 40...
The food industry is interested in utilizing active compounds from agri-food waste to produce healthy products and promote sustainability and resource efficiency. This study aimed to conduct a phytochemical analysis of grape pomace derived from Vitis...
The rapid expansion of RNA therapeutics requires analytical methods that resolve molecular integrity, heterogeneity, and process-related impurities. Capillary electrophoresis (CE) provides direct RNA separation with low sample consumption and can be...
China is rich in magnetite mineral resources, but they are generally characterized by low grade, fine dissemination size, and a high content of harmful impurities. Wet low-intensity magnetic separation (WLIMS) is an important method for processing fi...
Self-supported gradient bilayer NaA zeolite membranes were hydrothermally converted from geopolymer precursors for pervaporative dehydration of the propylene glycol methyl ether (PGME)/water azeotrope. XRD confirms crystallization of amorphous geopol...
A preparative purification process was developed for the enrichment of four C-glycosyl flavones from leaves of Phyllostachys edulis (Carrière) J.Houz., namely orientin, isoorientin, vitexin, and isovitexin. The crude P. edulis leaf extract was...
