In response to the limitations of traditional total antioxidant capacity (TAC) determination methods—namely limited sensitivity and weak anti-interference ability—as well as the reliance on toxic hydrogen peroxide in conventional nanozyme-based sensing systems, silver nanoparticles (HA-AgNPs) with enzyme-mimicking catalytic activity were synthesized using hydroxylamine hydrochloride as the reducin
Bacilladnaviridae is a family of viruses with single-stranded, circular DNA genomes that range from 3.4 to 6 kb and contain a short double-stranded region of 0.5–1 kb. The genome is replicated by the rolling-circle mechanism. Bacilladnavirids encode a jelly-roll capsid protein which forms non-enveloped icosahedral capsids with a T=3 symmetry. All cultured bacilladnavirids infect diatoms, a g
This study presents a generic method to selectively enhance radiative pathways over non-radiative states by leveraging vibrational coupling between the host lattice and mid-gap states of doped transition metal ions. While previously demonstrated with Mn, this work successfully incorporates Ni 2+ ions into CsPbCl 3 perovskite nanocrystals (NCs), showcasing the method's versatility and tunability
Doped perovskite lead halide nanocrystals (PHNCs) are promising materials for various optoelectronic applications, but the major challenge faced by the researchers is the inability to dope foreign elements into perovskite lattice because of the strong lead-halide bond energies. In this work, we have used Fe as a dopant in CsPbCl3 to explore different doping techniques based on the colloidal s
Lead halide perovskite (CsPbX3, where X = Cl, Br, or I) quantum dots (QDs), with tunable optical and electronic properties, have attracted attention because of their promising applications in solar cells and next-generation optoelectronic devices. Hence, it is crucial to investigate in detail the fundamental size-dependent properties of these perovskite QDs to obtain high-quality nanocrystals for
The optical and electronic properties of lead halide perovskite nanocrystals have been explored extensively due to their increasing demand in photovoltaic and optoelectronic applications. But little is known about the growth kinetics of these nanocrystals. In this work, we demonstrate an interesting new mechanism using the method of arrested growth and precipitation to isolate the intermediates. W
Herein we report the use of a hue parameter of HSV (Hue, Saturation and Value) color space—in combination with chromaticity color coordinates—for exploring the complexation-induced luminescence color changes, ranging from blue to green to yellow to white, from a non-luminescent Fe-doped ZnS quantum dot (QD). Importantly, the surface complexation reaction helped a presynthesized non-luminescen
Granular activated carbon (GAC) filtration is increasingly used for quaternary treatment of municipal wastewater to remove organic micropollutants, in line with the revised EU Urban Wastewater Treatment Directive (Directive (EU) 2024/3019). This review compiles and synthesises available, peer-reviewed, and long-term pilot- and full-scale studies and, in contrast to previous reviews, particularly a
Rapid adaptive evolution can increase the competitive ability of invasive species in their non-native ranges. However, whether this increase is a general response and what drives it remain uncertain because the evidence is largely based on studies with limited sampling, inadequate consideration of population co-ancestry, and oversimplified estimates of competitive ability. We conduct a large-scale
Mixing at the microfluidic scale is challenging due to the low Reynolds numbers and often high Péclet numbers. Without turbulence, mixing relies solely on diffusion, resulting in slow and inefficient mixing. We demonstrate enhanced mixing in a simple Y-shaped microfluidic channel using viscoelastic turbulence in fluids containing macromolecules, such as DNA and polyethylene oxide. We investigated
Den biologiska mångfalden i EU är hotad. För att naturen ska kunna återhämta sig har EU tagit fram naturrestaureringsförordningen med bindande och tidsatta mål för EU:s medlemsstater. Ett delmål inom restaureringsförordningen är att öka diversiteten och nå gynnsam bevarandestatus för vilda pollinerande insekter (pollinatörer). Genom en separat, delegerad förordning (DF) har det slagits fast att EU
Water and wastewater contain complex mixtures of chemical contaminants whose composition varies between locations, sample matrices, and treatment processes. This creates analytical challenges because different analytical strategies provide different balances between chemical coverage, identification confidence, and quantitative reliability. Target analysis can provide sensitive andquantitative inf
Swedish building envelopes are energy efficient due to thicker insulation and improved airtightness, which can reduce drying potential and increase the risk of moisture-related damage. Hygrothermal simulation supports moisture-safe design but predicted mould risk depends strongly on the representativeness of the exterior climate boundary conditions. This study compiled a quality-controlled 30-year
Machine intelligence is being employed for an increasing number of tasks in the healthcare sector. The more encompassing these tasks are becoming, the likelier it will be that, besides working with empirical data, algorithms are also coming into contact with normative aspects. This is a consequence of the fact that doing medicine is intimately intertwined with the making of value judgments. Will t
Covalently cross-linked whey protein microgels (WPM) were produced without the use of a chemical cross-linking agent. The hierarchical structure of WPM is formed by a complex interplay of heat denaturation, aggregation, electrostatic repulsion, and formation of disulfide bonds. Therefore, well-defined spherical particles with a diameter of several hundreds of nanometers and with relatively low pol
Water-in-oil-in-water double emulsions (W1/O/W2) consist of water droplets (W1) dispersed in oil globules (O), which are then redispersed in an external aqueous phase (W2). This paper reports multiple light scattering investigations on W1/O/W2 double emulsions, the inner W1/O emulsion being a concentrated micron sized inverse emulsion, and the outer O/W2 emulsion being a dense direct emulsion. Dou
We have investigated the structure of microgels formed during heating of demineralized β-lactoglobulin (βlg) solutions at pH 5.9 by small-angle X-ray scattering (SAXS) and light scattering. First, unheated βlg solutions were characterized at different pH values between 2.0 and 7.0. At pH 5.9, βlg solutions contain mainly dimers (with a radius of approx. 2nm), which coexist with a small number of l
We present a new 3D cross-correlation instrument that not only allows for static and dynamic scattering experiments with turbid samples but measures at four angles simultaneously. It thus extends the application of cross-correlation light scattering to time-resolved studies where we can, for example, efficiently investigate the temporal evolution of aggregating or phase separating turbid dispersio
Amphiphilic diblock copolymers such as poly(styrene)-block-poly(styrene sulfonate) (PS-b-PSS) (Matsuoka, H.; Maeda, S.; Kaewsaiha, P.; Matsumoto, K. Langmuir 2004, 20, 7412), belong to a class of new polymeric surfactants that ionize strongly in aqueous media. We investigated their self-assembly behavior in aqueous solutions and used them as an emulsifier to prepare electrosterically stabilized co
