Summary: The increased use of nanoparticles in various industries leads to their release into the environment, where plants come into direct contact with them. Studies on the uptake of nanoparticles by plants and their effects on plant developmental processes are still insufficient. Analysis of changes in the chemical components of cell walls exposed to gold nanoparticles showed that different surface charges of nanoparticles affect the presence and distribution of specific epitopes in root cells.

Summary: Plants use electrical and chemical signals for systemic communication, with herbivory triggering glutamate accumulation and calcium waves to report damage and initiate defense. By expressing fluorescent glutamate sensors in Arabidopsis, researchers found that displaying the sensors externally impacted plant growth and development. The study also revealed that sequestering glutamate at the cell surface disrupts meristematic cell supply and localized signaling, affecting root growth.

Summary: The MEDIATOR complex plays important roles in root biology, including root architecture, hormonal responses, nutrient stress adaptation, and meristem cell survival. Changes in the subunits and accessory histone acetyltransferases of MEDIATOR may affect gene expression. MEDIATOR interacts with TOPLESS and is involved in auxin and jasmonic acid responses, affecting the binding of transcriptional regulators to gene promoters. It also plays a crucial role in nutrient stress adaptation and plant productivity.

Summary: Root development is regulated by plant hormones, transcription factors, and recently identified small peptides and their receptors. Small peptides bind to receptors, inducing signaling for cell-to-cell communication and coordination of root development. The interconnection between peptide signaling and conventional phytohormone signaling, as well as the diversity of peptide-receptor interactions, have been discussed in recent studies.

Summary: Based on the research, the positioning of the lateral root (LR) is influenced by an internal spacing mechanism controlled by auxin oscillations known as the root clock. Surprisingly, none of the previously identified PIN and ABCB auxin transporters are involved in this LR prepatterning mechanism. However, the novel auxin-transporting ABCBs, ABCB15-22, were found to contribute to shootward auxin transport in the lateral root cap (LRC) and epidermis, thereby explaining the reduced auxin oscillation that correlates with strongly reduced LR densities. These findings suggest that LRC-derived auxin contributes to the amplitude of the root clock.

Summary: Gene expression is rapidly reconfigured during the cell cycle to carry out specific cellular functions for each phase. The use of fluorescence-activated cell sorting allowed for analysis of gene expression profile in G2/M cells in the growing root and identification of key regulatory factors. SCL28, a transcription factor, was found to play a crucial role in promoting progression through G2/M and modulating cell division plane selection.

Summary: This study investigated the influence of the (hafnium and zirconium)/molybdenum ratio on the microstructure and properties of Ti20Ta20Nb20(ZrHf)(20)Mo--x(x) (where: x = 0, 5, 10, 15, 20 at.%) high entropy alloys in an as-cast state. The results showed that the lattice parameters of the alloys decreased with increasing molybdenum concentration up to 10%, and then increased. Scanning and transmission electron microscopy confirmed the presence of a two-phase matrix microstructure and hafnium and zirconium precipitates. Mechanical property measurements revealed a decrease in hardness and Young's modulus up to 10% of Mo content, and then an increase up to 20% of molybdenum addition. Corrosion resistance measurements confirmed the high biomedical ability of the alloys.

Summary: The presented research thoroughly investigated the effects of print speed on glycol-modified polyethylene terephthalate (PETG) printed using fused filament fabrication (FFF) technology. The results showed that higher print speeds led to the formation of voids and other defects on the printed product's surface and inside. The surface profile and presence of pores were also significantly influenced by the print speed. In addition, the study found a non-monotonic relationship between polymer chain orientation and print speed using polarized Raman spectroscopy, while micromechanical properties slightly depended on the print speed.

Summary: This work presents a synthesis procedure for preparing vertically aligned mesoporous silica thin films with long nanometer-scale silver nanowires inside pores. The nanowires have a fine crystalline structure and a diameter of no more than 2 nm. The synthesis involves the use of silica nanoreactors and consists of two steps: fabricating an organically-functionalized silica thin film with regularly distributed silver ions inside vertically aligned pores, and thermally decomposing the film to form metallic crystalline nanowires. The resulting nanocomposite and initial material were characterized using electron microscopy and electrochemical techniques. The confinement provided by silica nanochannels enables the stabilization of small and ultra-thin nanowires and the formation of a hexagonal silver crystalline structure.

Summary: This study focuses on finding new methods for modifying the surface of the biomedical Ti-13Zr-13Nb alloy for applications in regenerative medicine and personalized medicine. Using anodizing in 0.5% HF electrolyte at 20 V for 120 min, oxide nanotube (ONTs) layers of first-generation (1G) were successfully produced on the Ti-13Zr-13Nb alloy. The physico-chemical characterization of the obtained 1G ONTs was conducted using TEM and ATR-FTIR methods. In vitro corrosion resistance of the 1G ONTs and the comparative Ti-13Zr-13Nb substrate was analyzed through various methods such as open-circuit potential, Tafel curves, anodic polarization curves, and EIS methods.

Summary: We report on the influence of Sr, Cr, Mn, and Mg doping ions on the structural and dielectric properties of barium calcium titanate (BCT) ceramics over a wide temperature and frequency range. Our findings reveal phase transitions from paraelectric to ferroelectric phases, distinguish diffused phase transition features induced by Cr and Mn ions, and highlight relaxor-like features caused by Mg ion doping. Additionally, the doping of Cr, Mn, and Mg ions affects the relaxation times of the B-sublattice ions jumping. Low-temperature ferroelectric-ferroelectric phase transitions were confirmed through dielectric and pyroelectric measurements, demonstrating the induction of non-zero net polarization by an applied electric field.

Summary: In this study, germanate phosphors Li2MgGeO4:Ln(3+) (Ln = Pr, Tm) were synthesized and their luminescence properties were investigated using spectroscopy. X-ray diffraction analysis showed that ceramic compounds Li2MgGeO4 with Pr3+ and Tm3+ ions crystallized in a monoclinic crystal lattice. The luminescence properties of Pr3+ and Tm3+ ions were examined under different excitation wavelengths. The most intense blue emission band of Tm3+ overlapped well with a broad band near 500 nm, while this effect was not evident for Pr3+ ions. Based on excitation/emission spectra and decay measurements, the germanate ceramics Li2MgGeO4 doped with trivalent rare earth ions can be used as inorganic phosphors emitting orange (Pr3+) or blue (Tm3+) light.
