Abstract Scaling the synergistic properties of MXene nanosheets to microporous aerogel architectures requires effective strategies overcome nanosheet restacking without compromising MXene's advantageous properties. Traditional assembly approaches 3D aerogels normally involve external binders/templates and/or additional functionalization, which sacrifice electrical conductivities and electrochemical activities aerogels. Herein, inspired by hierarchal scale textures Phrynosoma cornutum , a...
Functional food development faces a considerable hurdle due to the poor bioavailability of incorporated bioactive compounds, which are caused by aqueous solubility, rapid release, low circulation time, physical and chemical instability, cytotoxicity compounds. Encapsulation emerges as pivotal strategy address this challenge protecting bioactives. Protein wall material for encapsulation plays significant role its biocompatibility, non-toxicity, surface activity, amphiphilic nature, diverse...
Nucleation underlies the formation of many liquid-phase synthetic and natural materials with applications in chemistry, geochemistry, biophysics, structural biology. Most nucleation processes are heterogeneous, occurring at specific sites a solid–liquid interface; however, chemical topographical identity these how kinetics vary from site-to-site remain mysterious. Here we utilize situ liquid cell electron microscopy to unveil counterintuitive nanoscale nonuniformities heterogeneous on...
Liquid-phase transmission electron microscopy (LP-TEM) enables real-time imaging of nanoparticle self-assembly, formation, and etching with single nanometer resolution. Despite the importance organic capping ligands in these processes, effect beam irradiation on surface-bound soluble during LP-TEM has not been investigated. Here, we use correlative fluorescence (FM) to demonstrate that polymeric undergo competing crosslinking chain scission reactions nonmonotonically modify ligand coverage...
Abstract Assembling 2D‐material (2DM) nanosheets into micro‐ and macro‐architectures with augmented functionalities requires effective strategies to overcome nanosheet restacking. Conventional assembly approaches involve external binders and/or functionalization, which inevitably sacrifice 2DM's nanoscale properties. Noble metal ions (NMI) are promising ionic crosslinkers, can simultaneously assemble 2DM induce synergistic Herein, a collection of NMI–2DM complexes screened categorized two...
The aim of the current study is to examine validity and reliability online examinations through undergraduates’ lecturers’ perceptions identify ways in which can be more focused effective. To this end, a questionnaire including both qualitative quantitative inquiries were administered among forty-five undergraduates fifteen lecturers three state universities Sri Lanka. Thematic Analysis SPSS software used analyze data respectively. Findings indicate that 80% preferred traditional assessments...
Nucleation is ubiquitous during liquid phase crystallization processes, both in natural and synthetic systems [1], controls phenomena such as polymorph selection of drug molecules proteins, biomineral nucleation, vivo aggregation pathogenic synthesis nanomaterials.Except for very clean systems, nucleation almost always heterogeneous because the presence a solid interface significantly decreases free energy barrier to [2].The given site depends sensitively on local surface topography...
