Sunflowers are plants from the Asteraceae family which are popular as ornamental plants, as well as consumed in the form of microgreens. The problem with microgreen cultivation is that it requires light as a substitute for sunlight and is difficult to imbibition because it has a hard skin. The aims of this study were (1) to obtain the best light spectrum color on the growth and yield of sunflower microgreens, (2) to obtain the best soaking time for sunflower microgreen growth and yields, (3) to obtain the best interaction of light spectrum treatments and soaking time seed. The research method was arranged using a split plot experimental design in a randomized block design with 3 repetitions. The main plot are the light spectrum and the sub plots are the soaking time of the seeds. Variables observed: germination time, germination percentage, germination rate, microgreen height, sample weight per plot. The results showed that the white light spectrum produced the best germination percentage and germination rate, while the blue light spectrum produced the best microgreen height. Seed soaking time of 12 hours produced the best percentage of germination, germination rate, and weight per plot, while soaking time of 24 hours produced the best germination time and microgreen height. Blue light spectrum and 24 hours soaking time produced the best interaction on microgreen height, and weight per plot. White light spectrum and 12-hour soaking produced the best interaction on germination percentage.

Freshwater environments and coastal marine areas provide key ecosystem services to society and serve as habitats for biodiversity. However, they face major challenges from human activities and climate factors, leading to global degradation. The effect of these agents depends on geographic location and climate, among other factors. To comprehensively understand the effect of these factors, continuous, standardized and long-term information is crucial. In particular, the aquatic microbiome plays a fundamental role in the cycling of matter and has been shown to act as a robust indicator of ecological status. Long-term monitoring of microbial assemblages can provide valuable insights into the characteristics and the changes water bodies undergo, delivering early warnings of critical impacts. Thus, the Latin American Aquatic Microbial Observatory Network (AMOLat) was set up during the inaugural meeting of the Latin American Collaborative Network on Microbial Aquatic Ecology (μSudAqua) in 2017. Observatory sites were carefully chosen, considering their accessibility and local relevance to each research group, ensuring the ongoing consistency of sampling efforts. This work aims to provide a historical overview of the network’s formation, highlighting key debates and definitions that took place during 2017-2023. Furthermore, it includes an initial characterization of the observatory sites and explores the possibilities that they offer to understand the structure and function of aquatic ecosystems in Latin America. The network presently encompasses 13 observatories, spanning a broad latitudinal range, numerous ecoregions and diverse aquatic ecosystems, displaying different environmental and anthropic impacts. Participating groups enhanced interactions, created a Protocol Book and showcased initial results through various communication efforts. Ultimately, establishing a regional network of aquatic observatories becomes mandatory for providing essential reference points to assess the response of microorganisms to global change in both the short and long term within Latin America.

Published: November 2024

With the increasing demand for optical data transmission and processing by modern communication systems, high-speed optoelectronics operating at telecom wavelengths are greatly desired. Two-dimensional (2D) materials with high carrier mobility and picosecond intrinsic response times exhibit large potential in this respect. However, most reported 2D material photodetectors for the telecom C-band either suffer from a slow response speed or rely on integrated silicon waveguides, which is a consequence of the inefficient utilization of hot carriers in these devices. Here, we report a high-performance and waveguide-free WS2/graphene photodetector operating at 1560 nm enabled by hot carrier injection and long-lived charge separation. The efficiently injected hot electrons from graphene to WS2 exhibit ultrafast cooling dynamics with 3 ps intrinsic response time. Simultaneous hole trapping in WS2 ensures a long circulation of injected electrons, enabling a high responsivity of 0.26 A/W. In continuation, we present a vertical WS2/graphene/WSe2 device with a built-in electric field and the same detection mechanism, for which a photocurrent on-off ratio of 3500 and an extrinsic response time of 1.71 ns are obtained. Our study highlights the benefits of combing 2D semiconductors and semimetals for high-speed photodetection.
Divergent Activity Shifts of Sn-Based Catalysts for Electrochemical CO2 Reduction: pH-Dependent Behavior of Single-Atom vs. Polyatomic Structures
Authors: WANG Yuhang , Zhang Di , Sun Bin , Jia Xue , Zhang Linda , Cheng Hefeng , Fan Jun , Li Hao
Published: November 2024

Tin (Sn)-based catalysts have been widely studied for electrochemical CO2 reduction reaction (CO2RR) to produce formic acid, but the intricate influence of the structural sensitivity in single-atom Sn (e.g., Sn-N-C) and polyatomic Sn (e.g., SnOx and SnSx; x=1,2) on their pH-dependent performance remains enigmatic. Herein, we integrate large-scale data mining (with >2,300 CO2RR catalysts from available experimental literature during the past decade), ab initio computations, machine learning force field accelerated molecular dynamic simulations, and pH-field coupled microkinetic modelling to unravel their pH dependence. We reveal a fascinating contrast: the electric field response of the binding strength of *OCHO on Sn-N4-C and polyatomic Sn exhibits opposite behaviors due to their differing dipole moment changes upon *OCHO formation. Such response leads to an intriguing opposite pH-dependent volcano evolution for Sn-N4-C and polyatomic Sn. Subsequent experimental validations of turnover frequency and current density under both neutral and alkaline conditions well aligned with our theoretical predictions. Most importantly, our analysis suggests the necessity of distinct optimization strategies for *OCHO binding energy on different types of Sn-based catalysts.

Inverted singlet-triplet gap materials (INVEST) have emerged as an intriguing class of materials with potential applications as emitters in Organic Light Emitting Diodes (OLEDs). Indeed, this type of material exhibits a negative singlet-triplet energy gap (ΔEST), i.e., an inversion of the low-est singlet (S1) and triplet (T1) excited states, that goes against Hund’s rule. In this study, the ΔEST of a set of 15 INVEST molecules has been computed within the framework of Restricted Open-Shell Kohn-Sham (ROKS) and Delta Self-Consistent Field (ΔSCF) methods and the results benchmarked against wavefunction-based calculations performed at the EOM-CCSD, NEVPT2 and SCS-CC2 levels. We find that ROKS always (and wrongly) predicts a positive ΔEST with global hybrid, meta-GGA and long-range corrected functionals and that this is almost functional-independent. We also show that the only way to get an inverted gap was to resort to double hy-brid functionals. In contrast, using the above-mentioned functionals, ΔSCF usually gives a nega-tive ΔEST, although the results are largely functional-dependent. Overall, applying a ΔSCF meth-od based on the PBE0 functional provides the lowest MSD and MAD with respect to EOM-CCSD results. We further show that the singlet-triplet inversion is driven by different degrees of orbital relaxation in the singlet versus triplet state and that this is well captured by ΔSCF calcula-tions. As a matter of fact, this orbital relaxation in ΔSCF somehow mimics the involvement of double and higher-order excitations in EOM-CCSD, which leads to a difference in spatial locali-zation of the and spins, and accounts for spin polarization effects sourcing the negative ΔEST. However, care should be taken when using the ΔSCF method to screen materials with potential INVEST behavior in view of their limited quantitative correlation with reference EOM-CCSD results on the molecular data basis used here.

Microkinetic models (MKMs) are widely used within the computational heterogeneous catalysis community to investigate complex reaction mechanisms, rationalize experimental trends, and to accelerate the rational design of novel catalysts. However, constructing these models requires computationally expensive and manually tedious density functional theory (DFT) calculations for identifying transition states for each elementary reaction within the MKM. To address these challenges we demonstrate a novel protocol that uses the open-source kinetics workflow tool Pynta to automate the iterative training of a reactive machine learning potential (rMLP). Specifically, using the silver-catalyzed partial oxidation of methanol as a prototypical example, we first demonstrate our workflow by training an rMLP to accelerate the parallel calculation of DFT-quality transition states for all 53 reactions, achieving a 7x speedup compared to a DFT-only strategy. Detailed analysis of our training curriculum reveals the shortcomings of using an adaptive sampling scheme with a single rMLP model to describe all reactions within the MKM simultaneously. We show that these limitations can be overcome using a balanced "reaction class" approach that uses multiple rMLP models, each describing a single class of similar transition states. Finally, we demonstrate that our Pynta-based workflow is also compatible with large pre-trained foundational models. For example, by fine-tuning a top-performing graph neural network potential trained on the OC20 dataset, we observe an impressive 20x speedup with an 89\% success rate in identifying transition states. This work highlights the synergistic potential of integrating automated tools with machine learning to advance catalysis research.
Alternate InP Synthesis with Aminophosphines: Solution-Liquid-Solid Nanowire Growth

Indium phosphide nanowires are important components in high-speed electronics and optoelectronics, including photodetectors and photovoltaics. However, most syntheses either use high-temperature and costly vapor-phase methodology or highly toxic and pyrophoric tris(trimethylsilyl)phosphine. To expand on the success of the aminophosphine-based InP colloidal quantum dot synthesis, we developed a synthesis for thin (~13 nm) zincblende InP nanowires at 180 °C using indium tris(trifluoroacetate) and tris(diethylamino)phosphine. A flat nanoribbon morphology was identified by transmission electron and atomic force microscopy analysis, with the stoichiometric (110) lattice plane exposed. Nanowire growth proceeds through a solution-liquid-solid mechanism from in situ-formed indium metal nanoparticles. Molecular byproducts of tris(oleyl)aminophosphine oxide and N-oleyltrifluoroacetamide observed by 31P and 19F NMR spectroscopy inform a proposed mechanism of indium reduction by the aminophosphine. Morphological control over the nanowire product is achieved by varying the phosphorus injection to control the aspect ratio, the In:P ratio to toggle between nanowires and multipods, and the pre-hot injection evacuation step to favor a quantum dot product. Replacing the indium precursor with indium tris(trifluoromethanesulfonate) is found to make bulk zincblende InP nanowires with an average diameter of >250 nm and tens of microns in length.

Vaginal yeast infections, such as vulvovaginal candidiasis (VVC), affect nearly three out of four women worldwide. Re-occurrence is frequent and requires repeated treatments with oral, antifungal medications at high doses. Prolonged treatments contribute to development of resistant fungal strains and the risk of systemic adverse effects. Vaginal drug delivery can overcome several of the disadvantages associated with oral drug administration. However, current dosage forms, such as vaginal creams and gels, are rapidly expelled from the vaginal tract and require daily dosing to assure therapeutic outcome, thus jeopardizing patient compliance. Therefore, we developed rapidly dissolving microneedle arrays for local, vaginal delivery of antifungal drugs. Clotrimazole, a poorly water-soluble antifungal agent, was formulated in lipid-based nanocarriers (LNCs) and incorporated in the tips of microneedles. The antifungal activity was then tested against the most common VVC fungal strains, C. albicans and C. glabrata, using an in vitro disk diffusion assay and an explant model from bovine vaginal tissue. Antifungal activity increased when the LNCs were incorporated in the microneedles. Notably, the LNC-loaded microneedles inhibited fungal growth at a 10-fold lower drug dose than a commercial clotrimazole cream. Finally, a device prototype was manufactured, based on an intravaginal ring with multiple microneedle arrays on its surface. Local vaginal drug delivery using such microneedle-based devices could enable more effective treatment strategies for VVC.
Nuclear Quantum Effects in Chemical Bonding Theory: Inter/Intramolecular Hydrogen-Bonding Interactions

Nuclear quantum effects (NQEs) play a crucial role in a wide range of chemistry, from life science to mate- rial chemistry. This study employs the approaches based on the Born-Oppenheimer quantum chemistry calculations and the beyond and investigates NQEs in inter/intra- molecular hydrogen-bonding interactions. The chemical bond analyses with natural bond orbital and non-covalent interaction approaches revealed that NQEs generally en- hance hydrogen-bonding interaction for (HX)3 (X=F, OH, NH2), tropolone, malonaldehyde, 9-hydroxyphenalenone, and deuterated species. It was also clarified that hydrogen- bonding interaction in -H species is more ionic (less cova- lent) than in -D. These findings highlight the essential role of NQEs in controlling chemical bonds and have practical implications for designing new materials and understanding biological processes from a molecular electronic states’ point of view.
A DFT analysis for synthesizing vitamin A

Vitamin A deficiency (VAD) is a major nutritional concern in lower-income countries. It is responsible for thousands of deaths in those countries every year. Thus, finding the optimal route for vitamin A synthesis is essential, especially for the countries that are influenced by VAD. Three mechanisms of synthesizing Vitamin A have been evaluated by Density Functional Theory (DFT) calculations. This experiment investigated the BASF C15 + C5 Wittig approach, the Rhône-Poulenc C15 + C5 Julia approach, and the Kuraray C10 + C10 approach. The electronic energy, highest occupied molecular orbital energy, and dipole moments were calculated using the B3LYP functional and the 3-21g basis set. The energy profiles of these synthesis routes were compared to determine the most energetically favorable method. The Julia approach has the lowest energy change, indicating its higher efficiency in terms of energy compared to the Wittig and Kuraray methods. It is shown that other factors such as scalability and raw material availability should also be considered in industrial applications.

Group 13 TEMPO (2,2,6,6-tetramethylpiperidine 1-oxyl) complexes of the form (L)E(TEMPO)3 (L=THF (tetrahydrofuran) or Py (pyridine); E = Al, Ga, In) were prepared and structurally characterized. The complexes (THF)Ga(TEMPO)3 (1·THF) and (Py)In(TEMPO)3 (2·Py) are shown to heterolytically cleave H2 under mild conditions (3 atm, 20 ◦C, t ≤ 1 h). 1·THF reacts reversibly with H2 to form a formal H2-adduct that bears a Ga(III) hydride center and a protonated TEMPO ligand with concomitant loss of THF, consistent with Ga(III) and TEMPO functioning as Lewis acid and base, respectively. Conversely, 2·Py is reduced by H2 to form an intermediate dimer complex of monovalent {In(TEMPO)}2, which undergoes further reactivity with H2 to form elemental indium as determined by powder X-ray diffraction. Treatment of 2·Py with H2 and Ph3PSe forms binary InSe, in addition to Ph3P and TEMPOH, demonstrating that 2·Py functions as a molecular source of zerovalent indium under mildly reducing conditions. Computational studies support an intramolecular metal-ligand cooperativity pathway in the heterolytic cleavage of H2.

Influencer marketing has become a fundamental tool in advertising. At the same time, the presence of minors on social media has become widespread, especially on their parents’ channels, as seen with micro-influencer mothers (those with less than 100 000 followers). This study aims to understand their communication and engagement strategies through an exploratory data analysis of the Instagram activity of five micro-influencers during five months (August to December 2022), analyzing 276 posts. The research shows that, like instamoms, the profiles studied feature several brands employing different advertising techniques, often lacking transparency regarding their commercial relationships. Most posts that showcase brands do not include any disclosure about a commercial collaboration. Fashion brands appear more frequently, but the food sector is particularly concerning, as many promote unhealthy products. Minors play an essential role by appearing in the most-liked and commercial posts. The results highlight the involvement of minors in profiles that fail to comply with key industry regulations, despite a great deal of advertising activity occurs, along with a lack of transparency from both micro-influencers and brands.
