Summary: This study evaluated the intraspecific variability of common valerian in Poland, focusing on the developmental traits, chemical composition, and genetic parameters of wild-growing populations and a specific landrace. The results showed high developmental and chemical variabilities among the wild-growing populations, with no clear relation to their origin region. The wild-growing populations had higher levels of essential oils and lower seed germinability compared to the landrace.

Summary: A dementia case is diagnosed every three seconds worldwide, with 50-60% of cases being caused by Alzheimer's disease (AD). The deposition of amyloid beta (Aβ) is believed to be correlated with the onset of dementia, although it remains unclear whether Aβ is causative. Optogenetic techniques provide a precise way to regulate cellular dynamics and could offer a better understanding of the etiology of AD.

Summary: This study found that exogenous methionine could reduce Cd accumulation in valerian roots, while increasing Cd uptake in the shoots. The addition of phosphate affected root Cd contents due to increased apoplastic Cd binding. However, in the presence of methionine, the phosphate effect on root Cd accumulation was mainly due to increased symplastic mot Cd allocation.

Summary: In Alzheimer's disease, the inactive and active forms of acetylcholinesterase (AChE) exhibit differences in their glycosylation pattern, particularly in the presence of terminal mannoses in the active forms. Sporadic AD patients have reduced binding to terminal mannoses compared to non-demented individuals, while familial AD patients with PSEN1 gene mutations have higher binding. Furthermore, presenilin-1 (PS1) modulates AChE trafficking and maturation in Golgi regions, promoting the presence of active forms in the cell membrane.

Summary: This study numerically investigates the behavior of Martian micro-particles in a human alveolar model under Martian gravity. It considers various physical and physiological factors and makes important findings: 1) Martian particle deposition is sensitive to alveolar direction and respiratory depth, but not to wall motion pattern; 2) particle size and density affect the starting time and duration of deposition; 3) compared to Earth gravity, deposition efficiency decreases and deposition time is prolonged under Martian gravity. It concludes that particle deposition under Martian gravity differs significantly from that under Earth gravity.

Summary: In this work, optical convolution is achieved through a time-wavelength plane stretching approach on a microcomb-driven chip-based photonic processing unit. Optical neural networks (ONN) have greatly benefited from parallel convolution-operation technology, which utilizes the dimension of optical wavelength to enhance complexity and functionality. However, challenges in high-level integration and on-chip operation remain for this advanced architecture. The authors develop a dedicated control and operation protocol, enabling a record high weight precision and demonstrating comparable processing capability to that of a digital computer in proof-of-concept experiments.

Summary: Flexible perovskite solar cells are promising new energy devices with high defect tolerance, strong solar absorption, and low non-radiative carrier recombination rates. However, their operational stability and moisture corrosion resistance need improvement. This study developed a highly cross-linked, dense flexible encapsulation material AlOC using Plasma-Enhanced Molecular Layer Deposition. The resulting encapsulation film exhibited excellent barrier performance and flexibility, making it suitable for flexible perovskite solar cell applications.

Summary: Understanding how lunar dust particles deposit in the human respiratory system is crucial for protecting astronauts from lunar dust toxicity. A Euler-Lagrangian method is used to track the motion of lunar dust particles in a human oral airway model. The study considers different factors such as inspiration rates, particle sizes, abnormal pressures, and temperatures. The findings show that most lunar dust particles tend to enter the right lung, especially the upper right lobe. Lower ambient pressure leads to fewer particles depositing in the upper airway and more entering the lung. Lower temperature results in more particles depositing in the upper airway and fewer in the lung.

Summary: In this study, four ruthenium complexes modified with selenium-ether were synthesized and showed excellent antibacterial activity against Staphylococcus aureus (S. aureus). The most active complex, Ru(II)-4, efficiently targeted the bacterial cell membrane, preventing drug resistance and inhibiting biofilm formation. In toxicity experiments, Ru(II)-4 exhibited low mammalian toxicity. In vivo tests using both G. mellonella wax worms and mouse skin infection models confirmed the potential of Ru(II)-4 as an effective antibacterial agent against S. aureus infections, with minimal toxicity to mouse tissue. These findings highlight the promising strategy of introducing selenium-atom into ruthenium compounds for developing interesting antibacterial agents.

Summary: The researchers designed a sandwich-type transparent conductive electrode by combining atomic layer deposition ZnO and thermally evaporated Ag films, proving that its film conductivity and optical transmittance are superior to metal electrodes with the same thickness. By using an optimized solution-based thin and continuous CH3NH3PbI3 (MAPbI(3)) film as the light absorber layer, the semitransparent perovskite solar cells (ST-PSCs) achieved a power conversion efficiency of 10% and an average visible transmittance of 19.6%. These findings illustrate a novel structure design strategy to overcome the contradiction between the efficiency and transparency of ST-PSCs.

Summary: The increase in packaging and power density has resulted in a higher electric field strength between solder joints and increased potential for failure due to electrochemical migration. To enhance the anti-electrochemical migration ability of SAC305 solder, Cu6Sn5 nanoparticles (NPs) were added to the paste and their mechanism for inhibiting ECM was studied. Cu6Sn5 NPs were prepared through ultrasound-assisted chemical reduction and composite solder pastes were prepared by mechanically mixing them with SAC305. In situ observation showed that adding 0.6 wt% Cu6Sn5 NPs effectively inhibited ECM by prolonging the incubation period, but exceeding this amount led to accelerated failure. Furthermore, Cu6Sn5 NPs increased the threshold for instantaneous failure under high voltage.

Summary: This review focuses on the measurement methods used to evaluate the geometry and electrical properties of through-silicon vias (TSVs) and examines the reliability issues associated with TSVs in 3D integrated circuits (ICs). Non-destructive measurement techniques for TSV contours and copper fillings have been researched, including high-frequency signal analysis methods and thermal detection methods. The reliability risks of TSVs arise from various factors such as copper contamination, thermal fields in 3D-ICs, stress fields, noise coupling, and interactions between multiple physical fields. Designing reliable 3D-ICs with TSVs requires electrical characterization of copper contamination, assessment of stress distribution using micro-Raman spectroscopy and finite element simulations, and the proposal of shield insertion to mitigate cross-coupling effects.

Summary: An intermetallic compound (IMC) capsule was developed to optimize the interfacial properties of copper pillars by adding Co and overcome the oxidation tendency of Co. The transformation process of CoSn2 nanoparticles into CoSn3 at the nanoscale was comprehensively analyzed using in situ heating transmission electron microscopy (TEM). The experimental results showed that CoSn2 nanoparticle growth occurred through polymerization, while CoSn3 nanoparticle formation relied on the reaction between CoSn2 and Sn.
