... Copyright @ 2022 Elsevier B.V. measurement, enhancing biomolecule sensing [297]. Real-time pH monitoring is achieved with fluorescein isothiocyanate (FITC) conjugated UiO MOF (F-UiO MOFs) [298,299], while thermosensitive luminescent-MOFs (LnMOFs) detect intracellular temperature variations, differentiating healthy and diseased cells [300]. These advancements underscore the transformative role of MOFs in precision diagnostics. ...

... The steric hindrance of the alkyl-rich polymer coating better protects the NCs and reduces the surface trap density. In addition, the sulfonate anion, a soft Lewis base, provides more effective passivation of the surface Pb 2+ than the carboxylate anion from the commonly used OA ligand [95]. The encapsulation of CsPbBr 3 NPLs has also been achieved using (3-aminopropyl)triethoxysilane (APTES), which undergoes hydrolysis ( Fig. 5(b)). ...

... Among these metal oxides, CeO 2 and Sm 2 O 3 , considered as environmentally friendly and economically advantageous materials, are quite effective. For example, Liao et al. [18] introduced CeO 2 into MnO 2 using the electrospinning method, which exhibited more active oxygen species and higher oxygen storage capacity. The T 50 of soot oxidation was decreased from 439 to 376 • C under tight contact. ...

... Whereas below this particle size bond lengths increase with decreasing particle size. 15 In addition to an increase in surface bond lengths with decreasing particle size in the nanoscale region changes in other structure/ properties were identied by Leffler et al. 16 in anatase titania below a diameter of y29 nm. These include changes in the surface structure, a shi toward lower point of zero charge values, increasing bond ionic content and an increasing percent of the global surface area being positively charged. ...

... Iron (hydroxyl) oxide is a type of iron containing inorganic compounds that are widely present in soil and rocks, mainly including goethite (α-FeOOH), orthorhombic hematite (β-FeOOH), lepidocrocite (γ-FeOOH), magnetite (Fe 3 O 4 ) and ferrihydrite (Fe 5 HO 8 ·4H 2 O) [7][8][9][10]. Among them, goethite is the most important, and its unique crystal structure and physicochemical properties make it have important application value in many fields, such as adsorbents [11][12][13], catalyst carriers [14], magnetic materials [15][16][17], etc. However, the isomorphic substitution of goethite in soil is a complex and interesting phenomenon that involves ion exchange processes in mineral lattices. ...

... [26,29] The high crystalline is adverse to the migration of small chain segments as the ion transport is prone in the amorphous regions. [10,97] The coordination structure can be expounded in PEO-Zn chloride (ZnCl 2 ) solid polymer electrolytes. [98] However, a sluggish diffusion of Zn 2+ with an ultra-low ionic conductivity at room temperature is achieved for the PEO electrolyte. ...

... Based on the above discussion and previous findings, [12,[25][26][27]38,[50][51][52][53] the roles played by oxygen vacancies in CO 2 hydrogenation reactions can be summarized. First, gaseous CO 2 could be effectively captured (CO 2 adsorption) and subsequently converted into active species including carbonate, bicarbonate, formate, etc (CO 2 activation and conversion) at oxygen vacancies. ...

... Natural mineral clay offers the advantages of affordability and excellent physical and chemical properties, making it a viable alternative to traditional supports. Chen et al. [46] utilized natural mineral clay as a support for DRM reactions, and characterization techniques revealed that the catalysts exhibited good activity and stability. Biomass charcoal surfaces contain numerous functional groups, such as carboxyl, hydroxyl, carbonyl, phenolic hydroxyl, lactone group, ether bond, and other polar or non-polar functional groups. ...
