Multifunctional nanoparticles for imaging and treatment in cancer are getting more and more attention recently. Herein, halloysite nanotubes (HNTs), natural clay nanotubes, are designed as multifunctional nanoplatform for targeted delivering photothermal therapy agents and chemotherapeutic drugs. Fe 3 O 4 was anchored…
Molecular substitutions were used to demonstrate preferential control over the kinetic rate constants in a poly(ethylene glycol)-based hydrogel with two different reversible thia-conjugate addition reactions. A strong electron-withdrawing nitrile group on the conjugate acceptor showed a 20-fold increase in the forward…
Solanum lycocarpum fruits contain two major glycoalkaloids (GAs), solamargine (SM) and solasonine (SS). These compounds are reported as cytotoxic. However, they have poor water solubility and low bioavailability. To overcome these disadvantages and getting an efficient formulation the current study aimed to develop, c…
Despite the wide utilization of amorphous solid dispersions (ASDs) for formulating poorly water-soluble drugs, fundamental understanding of the structural basis behind their stability and dissolution behavior is limited. This is largely due to the lack of high-resolution structural tools for investigating multicompone…
Following a screening of Antarctic glacier forefield-bacteria for novel cold-active enzymes, a psychrophilic strain Psychrobacter sp. 94-6PB was selected for further characterization of enzymatic activities. The strain produced lipases and proteases in the temperature range of 4-18ºC. The coding sequence of an extrace…
Raw bentonite was characterised and employed for adsorption of Cs(I), Sr(II), Co(II) and U(VI) from aqueous solution. Batch adsorption methodology was applied to study the factors influencing the adsorption capacity of bentonite. Thermodynamic parameters, ΔH°, ΔS°, and ΔG° were calculated and revealed that the sorptio…
Abstract Following the fundamental research conducted by J. B. Goodenough, the important role of electron localization induced by elemental substitution is studied. The size and electron negativity of host and substituting ions are two important factors in tuning material properties such as local structure and transit…
Abstract Hierarchical porous carbons (HPCs) are highly efficient supports for various remarkable catalytic systems. However, templates are commonly utilized for the preparation of HPCs, and the postremoval of the templates is uneconomical, time‐consuming, and harmful for the environment in most cases. Herein, a new hu…
The mycelial pellet is a microbial aggregator formed under certain conditions. Besides the ability to secrete metabolites and adsorb a large amount of pollutants, the mycelial pellet has the characteristics of high biological activity, fast sedimentation speed, and easy solid–liquid separation. The technology of the m…
Ti-6Al-4 V and Ti-6Al-4 V ELI alloys were surface modified with nanotube layers by electrochemical anodisation technique. Osteoblast cell viability and their osteogenic behaviour were studied. It was found that the pore diameters of the nanotubes were in the range of 70–105 nm for Ti-6Al-4 V sample and 60–130 nm for T…
Chemical solution deposition (CSD) of YBa 2 Cu 3 O 7−δ (YBCO) nanocomposites from colloidal precursor solutions containing double metal oxide preformed nanocrystals is a promising, cost-effective, and reproducible approach to producing superconducting films with high critical current density ( J c ) and enhanced pinni…
Introducing mRNA into cells has attracted intense interest for diverse applications; however, success requires delivery solutions. Engineered nanomaterials have been applied as mRNA nanocarriers; their functions are designed mainly as delivery vehicles, but rarely in regulation of the protein translation. Recently, pr…
The use of light-activated chemical probes to study biological interactions was first discovered in the 1960s, and has since found many applications in studying diseases and gaining deeper insight into various cellular mechanisms involving protein-protein, protein-nucleic acid, protein-ligand (drug, probe), and protei…
Abstract The use of a nonclassical light source for studying molecular electronic structure has been of great interest in many applications. Here we report a theoretical study of entangled two-photon absorption (ETPA) in organic chromophores, and we provide new insight into the quantitative relation between ETPA and t…
The molecular aggregation of nonfullerene acceptors (NFA) can significantly affect the light absorption, charge generation, and power conversion efficiency (PCE) of organic solar cells (OSCs). In this work, we demonstrate the regulation of J-aggregation of CO i 8DFIC NFA toward near-infrared absorption via solvent add…
Injured tendons are challenging in their regeneration; thus, tissue engineering represents a promising solution. This research tests the hypothesis that the response of amniotic epithelial stem cells (AECs) can be modulated by fiber diameter size of tendon biomimetic fleeces. Particularly, the effect of electrospun po…
Gastric carcinoma is one of the most lethal malignant tumors. As part of our long-term efforts on seeking effective diagnosis and therapeutic strategies of gastric cancer, we present herein novel ternary copper-based chalcogenide nanoplatform CuS–NiS2 nanomaterials with outstanding photothermal (PT)/photodynamic (PD)…
Incorporation of fluorinated moieties in polymeric nanoparticles has been shown in many instances to increase their uptake by living cells and, hence, has proven to be a useful approach to enhancing delivery to cells. However, it remains unclear how incorporation of fluorine affects critical transport processes, such…
Abstract Catalyst support with good conductivity and stability is an eternal pursuit in the search for a high‐performance electrocatalyst. Here, an unusual catalyst support, laser‐modified boron nitride with C, O dopants (L‐BN), for the oxygen evolution reaction is reported. L‐BN exhibits unique advantages for electro…
Membrane proteins possess a variety of functions essential to the survival of organisms. However, due to their inherent hydrophobic nature, it is extremely difficult to probe the structure and dynamic properties of membrane proteins using traditional biophysical techniques, particularly in their native environments. E…
