Article
Rechargeable lithium metal batteries (LMBs) are deemed as a viable solution to improve the power and/or energy density of the contemporary lithium‐ion batteries (LIBs). However, poor Li‐ion diffusivity within high‐energy cathodes causes sluggish kinetics of the corresponding redox reactions particularly at high C‐rates, thereby largely impeding the...

The use of two types of bulky cations, tetrabutylammonium (TBA⁺) and Cs⁺, as electrolyte additives in Na-O2 batteries is investigated. These cations facilitate the stabilization of sodium superoxide in the electrolyte, promoting the solution-mediated pathway. Both the addition of TBA⁺ and Cs⁺ favor the growth of larger NaO2 cubes than in the case o...
Article
The abundance of the available sodium sources has led to rapid progress in sodium-ion batteries (SIBs), making them potential candidates for immediate replacement of lithium-ion batteries (LIBs). However, commercialization of SIBs has been hampered by their fading efficiency due to the sodium consumed in the formation of solid-electrolyte interphas...
Article
Safe and efficient utilization of electrochemical energy is of prime importance for e-mobility and sustainable development of the current society. Solid state batteries (SSBs) have emerged as one of the most promising solutions to address aforementioned challenges due to the replacement of conventional liquid electrolytes with inherently safer soli...

Full-text available
A series of electrospun binder‐free carbon nanofibre (CNFs) mats have been studied, for the first time, as air cathodes for Na‐oxygen batteries using a pyrrolidinium‐based electrolyte and compared with the commercial air cathode Toray 090. A 10‐fold increase in the discharge capacity has been attained using a CNFs in comparison with Toray 090, achi...
Article
Submicron-sized poly(lactide-co-glycolide) nanoparticles (PLGA-NPs) stabilised with bovine serum albumin (BSA) are dual radiolabelled using gamma emitters with different energy spectra incorporated into the core and coating. PLGA core is labelled by encapsulation of 111 In-doped iron oxide NPs inside PLGA-NPs during NP preparation, while the BSA co...
Article
Mono-, bis-, and tris-1,2,3-triazole ligands are used for the stabilization of gold nanoparticles (AuNPs), and the catalytic activities of these AuNPs in 4-nitrophenol reduction by NaBH4 in water are compared as well as with polyethylene glycol 2000 (PEG)- and polyvinylpyrrolidone (PVP)-stabilized AuNPs. The excellent catalytic results specifically...
Article
The determination of nanoparticle (NP) stability and degradation in vivo is essential for the accurate evaluation of NP biodistribution in medical applications and for understanding their toxicological effects. Such determination is particularly challenging because NPs are extremely difficult to detect and quantify once distributed in a biological...
Article
Monofunctional triazoles linked to ferrocene, ferricenium, or coumarin (Cou), easily synthesized by copper-catalyzed azide alkyne (CuAAC) "click" reactions between the corresponding functional azides and (trimethylsilyl)acetylene followed by silyl group deprotection, provide a variety of convenient neutral ligands for the stabilization of functiona...
Article
A large family of bifunctional 1,2,3-triazole derivatives that contain both a polyethylene glycol (PEG) chain and another functional fragment (e.g., a polymer, dendron, alcohol, carboxylic acid, allyl, fluorescence dye, redox-robust metal complex, or a β-cyclodextrin unit) has been synthesized by facile “click” chemistry and mildly coordinated to n...
Article
Two new water-soluble 1,2,3-triazole-containing nona-PEG-branched dendrimers are obtained with nine intradendritic 1,2,3-triazoles (trz). Addition of HAuCl4 in water to these dendrimers quantitatively leads to the intradendritic formation of AuCl3(trz) moieties subsequent to complete Cl(-) substitution by trz on Au(III), whereas the analogous compl...
Article
Nanoparticle-supported tris(triazolyl)-CuBr, with a diameter of approximately 25 nm measured by TEM spectroscopy, has been easily prepared, and its catalytic activity was evaluated in the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. In initial experiments, 0.5 mol % loading successfully promoted the CuAAC reaction between benzyl az...
Article
The intracellular degradation of poly(lactide-co-glycolide) (PLGA) nanoparticles (NPs) is studied by means of flow cytometry (FACS). NPs are prepared with PLGA of two different ratios of the D,L-lactide and glycolide blocks: 85 : 15 and 65 : 35. PLGA molecules are labelled with rhodamine B. Flow cytometry is first used to follow the degradation of...
Article
Poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) incorporating quantum dots (QDs), superparamagnetic iron oxide nanoparticles (SPIONs) and gold (Au) NPs for neutrophil labeling were fabricated via the w/o/w double emulsion method. QDs and SPIONs were entrapped in the PLGA core during emulsification while Au NPs were assembled on top of the...
