Abstract High energy density lithium metal batteries (LMBs) are promising next‐generation storage devices. However, the uncontrollable dendrite growth and huge volume change limit their practical applications. Here, a new Mg doped Li–LiB alloy with in situ formed lithiophilic 3D LiB skeleton (hereinafter called Li–B–Mg composite) is presented to suppress Li mitigate change. The exhibits superior conductive characteristics, which contributes reduction of local current homogenization incoming...
Chemiluminescence is a powerful analytical technique with many advantages, while aptamers are well-known as good molecular recognition units. However, aptamer-based chemiluminescence assays employed interface sensing, which often needed several immobilization, separation, and washing steps. To minimize the risks of contamination false-positive, we for first time proposed photocatalytic aptamer chemiluminescent system homogeneous, label-free, generic assay small molecules. After binding to...
The Li-plated behavior was modified and Li-dendrites were suppressed through the generation of lithiophilic vertically aligned NiO hexagonal nanoplates on a Ni foil.
In both experiment and molecular simulation, it is found that a higher pressure required to sustain the infiltration of smaller ions in molecular-sized nanochannel. Simulations indicate effective ion solubility infiltrated liquid reduced nearly zero. Because strong interactions between couples solid or phases, an external force continuously advance confined segment. The competition probability entry ion-couple formation causes observed ion-size-dependent characteristics.
Polymers under nanoconfinement can exhibit large alterations in dynamics from their bulk values due to an interface effect. However, understanding the effect remains a challenge, especially ultrafine region. In this work, we prepare new geometries with ∼10nm through controlled distributions of crystalline phases and amorphous model semi-crystalline polymer, i.e., polylactic acid. The broadband dielectric spectroscopy measurements show that leads elevation glass transition temperature strong...
In pure water a hydrothermally treated zeolite Y is hydrophilic, while with the addition of an electrolyte it can no longer be soaked up spontaneously. The effective degree hydrophobicity increases ion concentration, which reflected by increase in infiltration pressure. pressure-induced behavior not only determined cations, but also highly dependent on anion species. This phenomenon attributed to confinement effect nanopore walls.
Event detection (ED) and word sense disambiguation (WSD) are two similar tasks in that they both involve identifying the classes (i.e. event types or senses) of some a given sentence. It is thus possible to extract knowledge hidden data for WSD, utilize it improve performance on ED. In this work, we propose method transfer learned WSD ED by matching neural representations tasks. Our experiments widely used datasets demonstrate effectiveness proposed method.
The infiltration of glycerin in a lyophobic nanoporous silica gel is investigated experimentally, and the effective interfacial tension viscosity are discussed. While simple superposition principle can be employed for analysis tension, nanopore liquid no longer material constant. It highly dependent on pore size loading rate, much smaller than its bulk counterpart.
The concept of thermally-chargeable supercapacitor was discussed and validated experimentally. As two double-layer supercapacitor-type devices were placed at different temperatures connected, due to the thermal dependence surface charge structures, electrode potentials became different, energy could be harvested stored as electric energy. important effect ion concentration investigated. results quite from prediction conventional theory, which should attributed unique behaviors ions confined...
Water-ion interaction in a nanoconfined environment that deeply constrains spatial freedoms of local atomistic motion with unconventional coupling mechanisms beyond free, bulk state is essential to spark designs broad spectrum nanofluidic devices unique properties and functionalities. Here, it reported the between ions water molecules hydrophobic nanopore forms coordination network an density nearly fourfold counterpart. Such strong facilitates connectivity water-ion uncovered by...
In a calometric measurement of infiltration and defiltration pressurized liquid in hydrophobic MCM41, it is observed that nanopores the energy change between solid phases dependent on direction motion: exothermic endothermic. The sorption curves temperature variation are insensitive to loading rate. magnitude decrease smaller than increase infiltration, fitting well with hysteresis curve. These phenomena can be attributed confinement effect nanopore walls thermally/mechanically aided surface...
The accurate discrimination of single-nucleotide variants is great interest for disease diagnosis and clinical treatments. In this work, a unique DNA probe with "Hill-type" cooperativity was first developed based on toehold-mediated strand displacement processes. Under simulation, owns thermodynamics advantage specificity due to two mismatch bubbles formed in the presence variants. Besides, strategies ΔG' = 0 more competitive strands are also beneficial discriminate feasibility successfully...
In a previous work we developed volume-memory liquid that can expand or shrink significantly as the temperature varies. The working mechanism is based on thermally induced infiltration and defiltration of an electrolyte solution in nanopores. current study, investigate influence concentration behavior, well its dependence temperature. testing data show that, varies, effective interfacial tension changes rapidly. This phenomenon be attributed to amplification effect nanopore surfaces...
In the past, energy absorption of protection/damping materials is mainly based on dissipation, which causes a fundamental conflict between requirements safety/comfort and efficiency. current study, nanofluidic "energy capture" system reported, nanoporous nonwetting liquid. Both molecular dynamics simulations experiments show that as liquid overcomes capillary effect infiltrates into nanopores, mechanical stress wave could be temporarily stored by confined phase isolated from transmission...
The liquid nanofoam (LN), a system composed of and hydrophobic nanoporous particles, is promising energy absorbing material. Despite its excellent capabilities under quasi-static conditions, the LN’s performance limited dynamic impacts due to heterogeneity. We hypothesize that absorption capacity LN can be increased by reconfiguration material into marble form. To test this hypothesis, we have prepared sample in two different configurations, one with heterogeneous layered structure other...
This work introduces a new mechanically triggered thermal runaway mitigation mechanism. The homogenizer of electrode failure (HEF), multiwall carbon nanotube (MWCNT), was added into LiNi0.5Mn0.3Co0.2O2 (NMC532) battery electrodes. We have studied the effect HEF additive on internal electrical resistance and mechanical impact additional MWCNTs reduced electrodes before abuse. Upon abuse, they could mitigate shorting at normal working temperature.
Liquid flow in nano-environment has been utilized as an advanced mechanism of energy absorption. While the process liquid outflow from nanopores shown to have a significant effect on system’s absorption efficiencies, its remains poorly understood. Here, we studied defiltration behavior nanofoam (LN) systems by controlling infiltration depth. The LN samples, composed different non-wettable phase and hydrophobic nanoporous silica with wide pore size distribution, compressed two loading modes...
Significance The outflow of prior confined or intruded liquid from a hydrophobic pore at the nanoscale is foundation for devising nanofluidics-enabled, reusable functional materials, structures, and devices fundamentally different that macroscale due to nanoconfinement effects.
