Chip stacking using through-silicon via (TSV) and direct copper-to-copper (Cu─Cu) bonding technology has emerged as a superior solution to overcome the limitations of Moore's law. However, conventional approaches face a fundamental trade-off: coarse-grained Cu requires high bonding temperatures (>300 °C), while nanograined Cu is unstable and tends to coarsen even at room temperature after electroplating. Here, this paradigm is broken through a unique composite copper (comp-Cu) architecture featuring alternating nanograin (ng─Cu) and (111)-oriented nanotwin (nt─Cu) domains.

Article Synopsis
  • * Over 80% of the identified CPEH strains belong to the high-risk ST78 lineage, which carries a specific plasmid (pOXA48-CREH) related to another endemic plasmid found in a different lineage (ST11).
  • * The research indicates that the ST78 lineage has rapidly spread and acquired various plasmids that facilitate carbapenem resistance, emphasizing the need for ongoing genomic monitoring and strategic measures to contain this threat in hospitals.

A series of bifunctional compounds have been discovered for their dual functionality as MER/AXL inhibitors and immune modulators. The furanopyrimidine scaffold, renowned for its suitability in kinase inhibitor discovery, offers at least three distinct pharmacophore access points. Insights from molecular modeling studies guided hit-to-lead optimization, which revealed that the 1,3-diketone side chain hybridized with furanopyrimidine scaffold that respectively combined amino-type substituent and 1-pyrazol-4-yl substituent on the top and bottom of the aryl regions to produce and , exhibiting potent antitumor activities in various syngeneic and xenograft models.

  • Autism spectrum disorder (ASD) affects over 1% of the global population, causing social difficulties and repetitive behaviors, often alongside other conditions like anxiety.
  • Research on mice exposed to valproic acid (VPA) as a prenatal factor suggests that the probiotic PS128 may improve behavioral symptoms in ASD by restoring dendritic structure and oxytocin levels.
  • These findings point to PS128’s potential in altering gut microbiota and supporting the development of new therapies for ASD.

Carbapenem-resistant ST11_KL64 emerged as a significant public health concern in Taiwan, peaking between 2013 and 2015, with the majority of isolates exhibiting OXA-48 as the sole carbapenemase. In this study, we employed whole-genome sequencing to investigate the molecular underpinnings of ST11_KL64 isolates collected from 2013 to 2021. Phylogenomic analysis revealed a notable genetic divergence between the ST11_KL64 strains in Taiwan and those in China, suggesting an independent evolutionary trajectory.

Long-term potentiation (LTP) is one of the major cellular mechanisms for learning and memory. Activity-dependent increases in surface AMPA receptors (AMPARs) are important for enhanced synaptic efficacy during LTP. Here, we report a novel function of a secretory trafficking protein, ICA69, in AMPAR trafficking, synaptic plasticity, and animal cognition.

Article Synopsis
  • The study investigates how varying concentrations of bis-(3-sulfopropyl) disulfide (SPS) in electroplated copper (Cu) foils impact their mechanical properties, particularly during tensile tests.
  • It finds that the SPS concentration influences the grain size of the Cu foils, which is crucial for their reliability in electronic packaging applications.
  • The research highlights a significant Hall-Petch effect, where changes in grain size due to SPS impurities lead to different fracture behaviors in the material.

The performance improvement of advanced electronic packaging material is an important topic to meet the stringent demands of modern semiconductor devices. This paper studies the incorporation of nano-alumina powder and thermoplastic elastomer (TPE) into thermoplastic polystyrene matrix to tune the thermal and mechanical properties after injection molding process. In the sample preparation, acetone was employed as a solvent to avoid the powder escape into surrounding during the mechanical mixing in a twin-screw mixer.

Solder/Cu joints are important components responsible for interconnection in microelectronics. Construction of the solder/Cu joints through liquid/solid (L/S) reactions accompanies the formation of the Cu-Sn intermetallic compounds (IMCs) at the joint interface. The CuSn IMC exhibits remarkable distinctions in thickness and morphology upon increasing the L/S reaction time.

Covalent organic frameworks (COFs) are of great interest in the energy and optoelectronic fields due to their high porosity, superior thermal stability, and highly ordered conjugated architecture, which are beneficial for charge migration, charge separation, and light harvesting. In this study, polyimide COFs (PI-COFs) are synthesized through the condensation reaction of pyromellitic dianhydride (PMDA) with tris(4-aminophenyl) amine (TAPA) and then doped in the TiO photoelectrode of a dye-sensitized solar cell (DSSC) to co-work with N719 dye to explore their functionality. As a benchmark, the pristine DSSC without the doping of PI-COFs exhibits a power conversion efficiency of 9.

Background: Castration-resistant prostate cancer (CRPC) with sustained androgen receptor (AR) signaling remains a critical clinical challenge, despite androgen depletion therapy. The Jumonji C-containing histone lysine demethylase family 4 (KDM4) members, KDM4A‒KDM4C, serve as critical coactivators of AR to promote tumor growth in prostate cancer and are candidate therapeutic targets to overcome AR mutations/alterations-mediated resistance in CRPC.

Methods: In this study, using a structure-based approach, we identified a natural product, myricetin, able to block the demethylation of histone 3 lysine 9 trimethylation by KDM4 members and evaluated its effects on CRPC.

The development of multiple intelligences used to focus on kindergartens and elementary schools as educational experts and officials considered that the development of students' multiple intelligences should be cultivated from childhood and slowly promoted to other levels. Nevertheless, the framework of multiple intelligences should not be simply promoted in kindergartens and elementary schools, but was also suitable in high schools, universities, and even graduate schools or in-service training. Taking employees in Southern Taiwan Science Park as the research subjects, total 314 employees in high-tech industry are preceded the 16-week (3 h per week for total 48 h) experimental teaching research.

Epoxy with low viscosity and good fluidity before curing has been widely applied in the packaging of electronic and electrical devices. Nevertheless, its low flexibility and toughness renders the requirement of property improvement before it can be widely acceptable in dynamic loading applications. This study investigates the possible use of 2-hydroxyethyl methacrylate (HEMA) toughening agent and nano-powders, such as alumina, silicon dioxide, and carbon black, to form epoxy composites for dynamic property improvement.
