Data from: Preparation of isolated guard cells, containing cell walls, from Vicia faba
<p>Stomatal movement, initiated by specialized epidermal cells known as guard cells (GCs), plays a pivotal role in plant gas exchange and water use efficiency. Despite protocols existing for isolating GCs through proplasting for carrying out biochemical, physiological, and molecular studies, protocols for isolating GCs with their cell walls still intact have been lacking in the literature. In this paper, we introduce a method for the isolation of complete GCs from <em>Vicia faba </em>and show their membrane to remain impermeable through propidium iodide staining. This methodology enables further in-depth analyses into the cell wall composition of GCs, facilitating our understanding of structure-function relationship governing reversible actuation within cells.</p>
Comprehensive study of antimicrobial polycaprolactone/clay nanocomposite films: preparation, characterization, properties and degradation in simulated body fluid
<p>Even though the biodegradability of polycaprolactone (PCL) and its nanocomposites is lower compared to other biodegradable polyesters, this property and good biocompatibility are used for development of materials for drug delivery with a long-term effect. We prepared novel PCL/clay nanocomposite films with antimicrobials chlorhexidine (CH) or octenidine (OCT) combined with ZnO anchored on vermiculite (VER). The intercalation of CH and OCT into the interlayer of VER/ZnOVER was confirmed by XRD, FTIR and SEM. The organically modified nanofillers compared to VER (−46.0 mV) or ZnOVER (−34.9 mV) showed a positive ζ-potential (+30.7 mV (VER_CH), +21.9 mV (VER_OCT), +24.6 mV (ZnOVER_CH)) indicating a relatively stable materials, except ZnOVER_OCT (+8.6 mV), which strongly agglomerated.</p> <p>Thin PCL/clay films were prepared by solvent casting method and the effect of used nanofillers on structural, thermal, mechanical and antimicrobial properties followed by degradation under hydrolytic conditions was studied. The results showed that presence of ZnO significantly decreases thermal and mechanical stability. The nanofillers with the higher hydrophilic character are responsible for the fastest degradation of PCL matrix. Films possessed high antimicrobial efficiency in long time intervals, hence these nanocomposites open new avenues for the possible application of such materials for the drug delivery with a long-term effect.</p>

Data from: Determining ground-state phase diagrams on quantum computers via a generalized application of adiabatic state preparation
<p>Quantum phase transitions materialize as level crossings in the ground-state energy when the parameters of the Hamiltonian are varied. The resulting ground-state phase diagrams are straightforward to determine by exact diagonalization on classical computers, but are challenging on quantum computers because of the accuracy needed and the near degeneracy of competing states close to the level crossings. In this work, we use a local adiabatic ramp for state preparation to allow us to directly compute ground-state phase diagrams on a quantum computer via time evolution. This methodology is illustrated by examining the ground states of the XY model with a magnetic field in the z-direction in one dimension. We are able to calculate an accurate phase diagram on both two and three site systems using IBM quantum machines.</p>

Analysis table of optimal preparation conditions of expanded graphite
<p><span>The environmentally friendly preparation of sulfur-free expanded graphite (EG) remains a great challenge. A large amount of strong acids and strong oxidants were used in the preparation of expandable graphite, resulting in environmental pollution problems. Herein, a novel and green preparation method for sulfur-free expanded graphite (EG) has been developed. Sulfur-free EG was fabricated using natural flake graphite (NFG), sodium perchlorate (NaClO<sub>4</sub>), and oxalic acid (C<sub>2</sub>H<sub>2</sub>O<sub>4</sub>) as raw materials. The electrochemical oxidation method was applied to prepare sulfur-free expandable graphite, and microwave irradiation technology was adopted to prepare sulfur-free EG. The optimum weight ratio was as follows: NFG:NaClO<sub>4</sub>:C<sub>2</sub>H<sub>2</sub>O<sub>4</sub> = 1.5:10:2. The anodic oxidation occurred under a constant current density of 47 mA/cm<sup>2</sup>, and the intercalation reaction lasted for 60 min at ambient temperature. The largest expanded volume (EV) of sulfur-free EG was 290 mL/g. The FTIR spectrum proved that the ClO4<sup>−</sup> and COO<sup>−</sup> groups had entered the graphite layers. The SEM images showed that the graphite layers were completely opened, and the pore structure was clearly observed. The sulfur-free EG prepared by the method does not cause environmental pollution and has broad application prospects.</span></p>

Data from: Preparation of Pt and bamboo charcoal co-modified TiO2 for formaldehyde sensing at room temperature
<p>Anatase TiO<sub>2</sub> has evolved to be one of the most attractive materials for gas sensing due to its strong oxidation activity and excellent sensing properties. In this study, we prepared a Pt and bamboo charcoal co-modified nano-TiO<sub>2</sub> using one-pot hydrothermal process and applied it for detection of formaldehyde. The successful incorporation of precious metal Pt and bamboo charcoal onto TiO<sub>2</sub> was confirmed by SEM, TEM, EDS, XRD, and XPS. These modifiers significantly improved the response of TiO<sub>2</sub> to formaldehyde, e.g., the response signal increased by 4 times, while the response time decreased from 91.05 to 67.76 s. The sample with 0.5@Pt and 0.5@C bamboo charcoal performed the best. Our work showed the potential of using biomass-derived carbon to improve the detection of formaldehyde.</p>

Neighbor-detection causes shifts in allocation across multiple organs to prepare plants for light competition
<p>To maximize their fitness, plants have to adjust their allocation strategy according to their abiotic and biotic environments. Plants can use the ratio of red to far-red light (R:FR) to sense neighbors, allowing them to modify their growth in response to aboveground competition.</p> <p>In this study, we used supplemental FR light to artificially lower the R:FR of the lower leaves of common sunflowers (Helianthus annuus) to examine how plants change their growth in response to the threat of neighbors. We combined this treatment with a nitrogen fertilization treatment to investigate how responses to neighbor-detection interact with nitrogen limitation.</p> <p>Plants grown in low R:FR increased in height at the expense of root growth, resulting in nitrogen limitation that restricted leaf growth. However, we found that plants reduced their nitrogen investment into leaves in low R:FR. By weakening the nitrogen sink strength of these lower leaves before they experienced low photosynthetically active radiation, plants were able to preemptively allocate nitrogen to leaves higher in the canopy.</p> <p>Plants responded to the perception of neighbors by simultaneously diverting resources from root growth to stem elongation and from leaves threatened by neighbors to leaves that would pose a threat to neighbors. This whole-plant response to neighbor-detection enables plants to change their allocation in a way that simultaneously manages their limited nitrogen and prepares them for future light competition.</p>
