Abstract The growth behavior of intermetallic compounds (IMCs) at the liquid-solid interfaces in Cu/Sn/Cu interconnects during reflow 250 °C and 280 on a hot plate was investigated. Being different from symmetrical isothermal aging, interfacial IMCs showed clearly asymmetrical reflow, i.e., Cu 6 Sn 5 IMC cold end significantly enhanced while that 3 hindered especially end. It found temperature gradient had caused mass migration atoms toward end, resulting sufficient atomic flux for reaction...
Zinc anode-based aqueous batteries have attracted considerable interest for large-scale energy storage and wearable devices. Unfortunately, the formation of Zn dendrite, parasitic hydrogen evolution reaction (HER), irreversible by-products, seriously restrict their practical applications. Herein, a series compact uniform metal-organic frameworks (MOFs) films with precisely controlled thickness (150-600 nm) are constructed by pre-oxide gas deposition (POGD) method on foil. Under protection...
Abstract Zn interfacial issues involved dendrite evolution and undesired parasitic reactions are tough challenges to impede the progress of ion battery. Herein, dendrite‐free anode with boosted stability is achieved by four‐in‐one functional additive triethyl phosphate (TEP). Experiments theoretical calculation reveal that TEP participates in generation compact inorganic interface prevent from corrosion. Meanwhile, electrical double layer (EDL) reconstructed adsorbed molecules inner weakened...
Thermal management poses a critical challenge in the design of modern electronic packages. This letter presents diamond-on-chip-on-glass interposer (DoCoG) technology that incorporates polycrystalline diamond heat-spreader substrates known for their exceptional thermal conductivity. These diamonds are directly bonded to back-side silicon chips on glass interposer, resulting markedly enhanced cooling performance. The junction-to-ambient resistance dropped by 28.5% due integration diamond....
Layered manganese‐rich oxides (LMROs) are widely recognized as the leading cathode candidates for grid‐scale sodium‐ion batteries (SIBs) owing to their high specific capacities and cost benefits, but notorious Jahn‐Teller (J‐T) distortion of Mn3+ always induces severe structural degradation consequent rapid failure, impeding practical implementation such materials. Herein, we unveil "intrinsic against J‐T distortion" mechanism effectively stabilize layered frameworks LMRO cathodes. The...
We study heat conduction behavior of one-dimensional lattices with asymmetric, momentum conserving interparticle interactions. find that a certain degree interaction asymmetry, the conductivity measured in nonequilibrium stationary states converges thermodynamical limit. Our analysis suggests mass gradient resulting from asymmetric interactions may provide phonon scattering mechanism addition to caused by nonlinear
Abstract The application of zinc‐ion batteries (ZIBs) is seriously challenged by the poor stability Zn anode and cathode in aqueous solution, which closely associated with electrolyte structure water reactivity. Herein, issues both for can be simultaneously addressed via tuning solvation hybrid tripropyl phosphate (TPP) as co‐solvent. On anode, a robust poly‐inorganic solid interphase (SEI) layer comprised 3 (PO 4 ) 2 ‐ZnS‐ZnF species situ formed, effectively suppressing parasitic reaction...
An ultrahigh energy storage performance is achieved in the BNST-20% (Sc 0.5 Ta ) 4+ ceramic via chemical modification, which could induce evolution of oxygen vacancies and local polar phases to achieve a high saturation polarization.
An all-optical non-resonant photoacoustic spectroscopy system for multicomponent gas detection based on a silicon cantilever optical microphone (SCOM) and an aseismic cell is proposed demonstrated. The SCOM has high sensitivity of over 96.25 rad/Pa with fluctuation less than ± 1.56 dB between 5 Hz 250 Hz. Besides, the minimal detectable pressure (MDP) sensor 0.55 μPa·Hz-1/2 at 200 Hz, which indicates that fabricated low noise level. Six different gases CO2, CO, CH4, C2H6, C2H4, C2H2 are...
Purpose This study aims to investigate the critical success factors of digital transformation in construction industry and identify whether respondents' profiles influence their perceptions for transformation. Design/methodology/approach To achieve objectives, a literature review was first conducted based on technology-organization-environment (TOE) framework. Then questionnaire survey carried out. A total 86 people were surveyed this study, mainly from industry. At level data processing,...
