Recent Advancements and Perspectives of Low-Dimensional Halide Perovskites for Visual Perception and Optoelectronic Applications.

Low-dimensional (LD) halide perovskites have attracted considerable attention due to their distinctive structures and exceptional optoelectronic properties, including high absorption coefficients, extended charge carrier diffusion lengths, suppressed non-radiative recombination rates, and intense photoluminescence. A key advantage of LD perovskites is the tunability of their optical and electronic properties through the precise optimization of their structural arrangements and dimensionality. This review systematically examines recent progress in the synthesis and optoelectronic characterizations of LD perovskites, focusing on their structural, optical, and photophysical properties that underpin their versatility in diverse applications.

Integrated iontophoresis and sweat sensing paper-derived laser-induced graphene soft conductors.

The development of mechanically compliant, functional materials toward skin-integrated electronic systems has been a rapidly evolving field, aiming at flexible and even stretchable architectures that can be mounted into curved skin surfaces and adapt to their changing topography and biomechanics. One of the components required for functional bioelectronic systems is bioelectrodes that can robustly interact with the skin to perform sensing or stimulation tasks. In this work, paper-based laser-induced graphene is studied as a compatible material for skin-integrated systems for iontophoretic sweat stimulation and sweat metabolite sensing.

Microalgae-Based Hybrid Biophotoelectrode for Efficient Light Energy Conversion.

Photosynthetic microorganisms are promising candidates for sustainable energy production in photobio-electrochemical systems. However, integrating them with electrodes is challenging due to the compartmentalized nature of photosynthetic organelles. Microalgae, in particular, have a more complex cell structure than cyanobacteria, leading to low electron transfer rates and compromising electrochemical communication.

Engineered surface strategies to manage dental implant-related infections.

When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant-related infections-one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems. Despite extensive research, there is no consensus on the most effective protocol for managing peri-implantitis.

The Epstein-Barr virus EBNA1 protein binds to G-quadruplexes in its own mRNA hence controlling its expression and immune evasion of the virus.

The oncogenic Epstein-Barr virus (EBV) evades the immune system but has an Achilles heel: its genome maintenance protein (GMP) EBNA1, which is essential for viral genome replication, but also highly antigenic. Hence, the virus evolved a mechanism to limit the translation of EBNA1 mRNA to the minimum level which allows EBNA1 to fulfil its essential function while minimizing production of EBNA1-derived antigenic peptides. This mechanism involves the binding of the arginine-glycine-rich (RGG) motif of nucleolin (NCL), a host protein, to RNA G-quadruplexes (rG4) of the viral EBNA1 mRNA.

Photobiomodulation presents an anti-inflammatory effect, reflecting on the expression of receptors related to the pain process in a collagenase-induced tendinitis experimental model.

Pain associated with tendinopathy is a common and difficult to treat. A therapeutic strategy to control some chronic painful processes is the use of benzodiazepines, which act on their GABA receptors, producing a sedative and analgesic effect. Non-pharmacological approaches, such as photobiomodulation (PBM), have shown promising results in the control of inflammatory joint pain.

Exploring the Impact of Biotic and Abiotic Surfaces on Protein Binding Modulation and Bacteria Attachment: Integrating Biological and Mathematical Approaches.

The oral environment is composed of a diverse array of proteins, and any substrate inserted into this habitat promptly becomes subjected to protein adsorption and bacterial colonization. However, the predictive and modulatory nature of implant surfaces coated with salivary pellicle proteomes in microbial adhesion has not been explored using high-throughput techniques. Thus, using human saliva for salivary pellicle adsorption and microbial accumulation, we compared adsorption and community formation on titanium (Ti) biomaterials (implant devices) and dental surfaces (enamel and dentine).

Forest citizens and people-centered conservation in the Brazilian Amazon.

Demands for territorial recognition are foundational to the claiming of rights by forest-proximate people who attempt to conserve their forests. The rights of these often-marginalized populations have been largely overlooked by conservationists, yet they are central to achieving people-centered conservation. We further developed the concept of forest citizenship as a normative framework and analytical tool based on Brazilian social environmentalism (socioambientalismo), florestania (a former political project in Acre state), Latin American scholarship on ecological citizenship, and Eurocentric political philosophy.

ZnO Nanorod/Ag NanoparticleFunctionalized Paper Substrate for Sensitive SERS Detection of Environmental Contaminants.

In this work, we functionalize Whatman no 1 paper (WP) substrates with zinc oxide nanorods (ZnO NRs) decorated with silver nanoparticles (AgNPs) for detecting environmental contaminants. ZnO NRs were grown by hydrothermal synthesis assisted by microwave irradiation on WP substrate and subsequently decorated with AgNPs using the dewetting deposition method. WP substrates functionalized with ZnO NRs/AgNPs were used as a SERS platform for detecting rhodamine 6G (R6G) dye and the thiabendazole (TBZ) pesticide, widely used in modern agriculture for fungal disease protection in fruits and vegetables.

POU4F2 overexpression promotes the genesis of retinal ganglion cell-like projection neurons from late progenitors.

Retinal ganglion cells (RGCs) are the projection neurons of the retina, and their death promotes an irreversible blindness. Several factors were described to control their genesis during retinal development. These include Atoh7, a major orchestrator of the RGC program, and downstream targets of this transcription factor, including Pou4f factors, that in turn regulate key aspects of terminal differentiation.

The optimization of nonradiative recombination losses through interface engineering is key to the development of efficient, stable, and hysteresis-free perovskite solar cells (PSCs). In this study, for the first time in solar cell technology, we present a novel approach to interface modification by employing one-dimensional lepidocrocite (henceforth referred to as 1DL) TiO-based nanofilaments, NFs, between the mesoporous TiO (mp TiO) and halide perovskite film in PSCs to improve both the efficiency and stability of the devices. The 1DLs can be easily produced on the kilogram scale starting with cheap and earth-abundant precursor powders, such as TiC, TiN, TiB, etc.

Integration of spectroscopic techniques and machine learning for optimizing Phaeodactylum tricornutum cell and fucoxanthin productivity.

The development of sustainable and controlled microalgae bioprocesses relies on robust and rapid monitoring tools that facilitate continuous process optimization, ensuring high productivity and minimizing response times. In this work, we analyse the influence of medium formulation on the growth and productivity of axenic Phaeodactylum tricornutumcultures and use the resulting data to develop machine learning (ML) models based on spectroscopy. Our culture assays produced a comprehensive dataset of 255 observations, enabling us to train 55 (24+31) robust models that predict cells or fucoxanthin directly from either absorbance or 2D-fluorescence spectroscopy.
