PlumX: Facile preparation of glycine-based mesoporous graphitic carbons with embedded cobalt nanoparticles
A simple route has been developed for the preparation of mesoporous graphitic carbons with embedded cobalt nanoparticles just using glycine as a nitrogen source, cobalt nitrate and distilled water. After heating the mixture to 300 °C under magnetic stirring, a dry solid product was obtained, which was then carbonized at 900 ºC under argon atmosphere. Changing the glycine/Co molar ratio allowed controlling the size of the cobalt particles and their dispersion in the carbon matrix, the porosity of the carbon and its graphitic character.

Understanding the blade coated to roll-to-roll coated performance gap in organic photovoltaics

Título : Understanding the blade coated to roll-to-roll coated performance gap in organic photovoltaics
Autores: Rana Adel, Graham Morse, Francesco Silvestri, Esther Barrena, Eugenia Martinez-Ferrero, Mariano Campoy-Quiles, Priti Tiwana, Marco Stella

PlumX: Understanding the blade coated to roll-to-roll coated performance gap in organic photovoltaics
The fabrication of efficient organic photovoltaic (OPV) modules via high throughput methods is a crucial milestone to facilitate their commercialization. The achievement of reliable printing and coating processes for large-scale modules has, however, been challenging thus far. Indeed, the performance gap is large between cells produced at lab-scale and those resulting from industrial methods. Therefore, understanding the critical steps in the upscaling process is decisive to address the research efforts towards decreasing the aforementioned gap.

PlumX: Metal-Free Radical Dendrimers as MRI Contrast Agents for Glioblastoma Diagnosis: Ex Vivo and In Vivo Approaches
Simultaneously being a nonradiative and noninvasive technique makes magnetic resonance imaging (MRI) one of the highly required imaging approaches for the early diagnosis and follow-up of tumors, specifically for brain cancer. Paramagnetic gadolinium (Gd)-based contrast agents (CAs) are the most widely used ones in brain MRI acquisitions with special interest when assessing blood–brain barrier (BBB) integrity, a characteristic of high-grade tumors. However, alternatives to Gd-based contrast agents (CAs) are highly required to overcome their established toxicity.

Translational Covariance of Flexoelectricity at Ferroelectric Domain Walls

Título : Translational Covariance of Flexoelectricity at Ferroelectric Domain Walls
Autores: Oswaldo Diéguez and Massimiliano Stengel

PlumX: Translational Covariance of Flexoelectricity at Ferroelectric Domain Walls
Macroscopic descriptions of ferroelectrics have an obvious appeal in terms of efficiency and physical intuition. Their predictive power, however, has often been thwarted by the lack of a systematic procedure to extract the relevant materials parameters from the microscopics.

The reaction of [Co2(H2O)(TFMBz)4(py)4] (1) (TFMBz: 3,5-bis(trifluoromethyl)benzoate; py: pyridine) with 4,4′-bipyridine (bpy) in different solvents yields four coordination polymers with unlikely structures but with the same stoichiometry. Three of them contain similar ladder chains consisting of binuclear nodes “Co2(TFMBz)4”, in which two of the TFMBz ligands show bidentate bridge coordination, double linked to each adjacent node by bpy but packed in different fashions.

PlumX: Single-Step Electrochemical Liquid–Liquid–Solid-Assisted Growth of Ge–Sn Nanostructures as a Long-Life Anode Material with Boosted Areal Capacity
A single-step electrochemical liquid–liquid–solid (ec-LLS) deposition route is developed for growing nanowire-based Ge–Sn nanostructures with tailored morphologies and compositions. Composite films, submicron fibers, nanowires, and also three-dimensional (3D) hierarchical structures are fabricated in the same electrolyte, simply by varying the electrodeposition current density. COMSOL simulations indicate that the current density is able to generate sufficient Joule heating to activate the ec-LLS growth mode.

PlumX: Submolecular Resolution Imaging of P3HT:PCBM Nanostructured Films by Atomic Force Microscopy: Implications for Organic Solar Cells
The efficiency of organic bulk-heterojunction (BHJ) solar cells depends greatly on both the bulk and surface structure of the nanostructured bicontinuous interpenetrating network of materials, known as the active layer. The morphology of the top layer of a coated film is often resolved at the scale of a few nanometers, but fine details of the domains and the order within them are more difficult to identify. Here, we report a high-resolution atomic force microscopy (AFM) investigation of various stoichiometries of the well-studied poly(3-hexylthiophene):[6,6]-phenyl C61 butyric acid methyl ester (P3HT:PCBM) active layer mixture.

PlumX: Quatsomes Formulated with l-Prolinol-Derived Surfactants as Antibacterial Nanocarriers of (+)-Usnic Acid with Antioxidant Activity
The efficacy of the treatment of bacterial infection is seriously reduced because of antibiotic resistance; thus, therapeutic solutions against drug-resistant microbes are necessary. Nanoparticle-based solutions are particularly promising for meeting this challenge because they can offer intrinsic antimicrobial activity and sustained drug release at the target site. Herein, we present a newly developed nanovesicle system of the quatsome family, composed of l-prolinol-derived surfactants and cholesterol, which has noticeable antibacterial activity even on Gram-negative strains, demonstrating great potential for the treatment of bacterial infections.

PlumX: Highly Aligned Bacterial Nanocellulose Films Obtained During Static Biosynthesis in a Reproducible and Straightforward Approach
Bacterial nanocellulose (BNC) is usually produced as randomly-organized highly pure cellulose nanofibers films. Its high water-holding capacity, porosity, mechanical strength, and biocompatibility make it unique. Ordered structures are found in nature and the properties appearing upon aligning polymers fibers inspire everyone to achieve highly aligned BNC (A-BNC) films. This work takes advantage of natural bacteria biosynthesis in a reproducible and straightforward approach. Bacteria confined and statically incubated biosynthesized BNC nanofibers in a single direction without entanglement.

PlumX: Oscillatory patterns in redox gradient materials through wireless bipolar electrochemistry. The dynamic wave-like case of copper bipolar oxidation
Bipolar electrochemistry allows the development of processes in a wireless manner, with reactions occurring at the induced anodes and cathodes of an immersed conducting material in the electrolyte. As a result, a gradient oxidation state may appear along the main axis field on the surface or bulk of the material depending on the type of reaction available at each induced potential. Redox intercalation gradients have been observed, metal anodization, or deposition, and also reactions at the electrolyte in the nearby environment of the poles induced.
