Abstract Lithium metal is a promising anode candidate for the next-generation rechargeable battery due to its highest specific capacity (3860 mA h g −1 ) and lowest potential, but low Coulombic efficiency formation of lithium dendrites hinder practical application. Here, we report self-formed flexible hybrid solid - electrolyte interphase layer through co-deposition organosulfides/organopolysulfides inorganic salts using sulfur containing polymers as an additive in electrolyte. The serve...
A facile method for fabricating antifouling and high-flux nanofiltration (NF) membranes was developed based on bioinspired polydopamine (PDA). Polyethersulfone (PES) ultrafiltration membrane as the support first deposited a thin PDA layer then chemically modified by new kind of fluorinated polyamine via Michael addition reaction between quinone groups PDA. coating significantly reduced pore sizes PES endowed NF with high separation performance (flux about 46.1 L/(m2 h) under 0.1 MPa,...
The isotherm thickness and hydrogen-bonding interactions of water layers adsorbed on hydrophilic hydrophobic surfaces were quantified compared. modeled with an OH-terminated native oxide layer silicon a HF-etched terminated hydrogen, respectively. substrate allows the use attenuated total reflection infrared (ATR-IR) spectroscopy for quantitative measurement without interferences from gas phase water. On Si–OH surface, average strongly hydrogen-bonded increases up to ∼2 molecular as relative...
Lithium–sulfur (Li–S) batteries are promising candidates for high-energy storage devices due to high theoretical capacities of both the sulfur cathode and lithium (Li) metal anode. Considerable efforts have been devoted improving cathodes. However, issues associated with Li anodes, such as low Coulombic efficiency (CE) growth dendrites, remain unsolved unstable solid-electrolyte interphase (SEI) lead poor capacity retention a short cycling life Li–S batteries. In this work, we demonstrate...
The friction and wear behavior of materials are not intrinsic properties, but extrinsic properties; in other words, they can drastically vary depending on test environmental conditions. In ambient air, humidity is one such parameter. This paper reviews the effects macro- nano-scale various types materials. included this review graphite graphene, diamond-like carbon (DLC) films, ultrananocrystalline diamond (UNCD), transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN), boric...
Polymerization of allyl alcohol adsorbed and sheared at a silicon oxide interface is studied using tribo-tests in vapor phase lubrication conditions reactive molecular dynamics simulations. The load dependences product formation obtained from experiments simulations were consistent, indicating that the atomic-scale processes observable relevant to experiments. Analysis experimental results context mechanically assisted thermal reaction theory, combined with atomistic details available...
Abstract The application of lithium (Li) metal anodes in Li batteries has been hindered by growth dendrites, which lead to short cycling life. Here a Li‐ion‐affinity leaky film as protection layer is reported promote dendrite‐free anode. induces electrokinetic phenomena enhance Li‐ion transport, leading reduced concentration polarization and homogeneous distribution. As result, the anode during plating/stripping demonstrated even at an extremely high deposition capacity (6 mAh cm −2 )...
Shear-driven chemical reaction mechanisms are poorly understood because the relevant reactions often hidden between two solid surfaces moving in relative motion. Here, this phenomenon is explored by characterizing shear-induced polymerization that occur during vapor phase lubrication of α-pinene sliding hydroxylated and dehydroxylated silica surfaces, complemented reactive molecular dynamics simulations. The results suggest oxidative chemisorption molecules at surface sites, which transfers...
Interactions among antiwear additives (AWs), friction modifiers (FMs), and dispersant in a lubricating oil are critical for tribological performance. This study investigates compatibilities of three oil-soluble ionic liquids (ILs, candidate AWs) with an FM, molybdenum dithiocarbamate (MoDTC), dispersant, polyisobutene succinimide (PIBSI) under boundary lubrication. Either synergistic or antagonistic effects were observed depending on the IL's chemistry. Adding aprotic...
As much as 60 million liters of lubricating fluids end up in the environment annually, and thus, environmental impact lubricants is increasingly recognized addition to meeting rheological tribological requirements. Although US Environmental Protection Agency-approved environmentally acceptable base are available, there a lack additives that both nontoxic effective wear protection. This study reports successful development new class ionic liquids (ILs) with demonstrated significantly lower...
Physisorbed molecules at a sliding solid interface could be activated by mechanical shear and react with each other to form polymeric products that are often called tribopolymers. The dependence of the tribopolymerization yield on applied load adsorbate molecular structure was studied obtain mechanistic insights into mechanochemical reactions tribological stainless steel. Three hydrocarbon precursors containing 10 carbon atoms-α-pinene (C10H16), pinane (C10H18), n-decane (C10H22)-were chosen...
Increasing concerns on resource depletion and environmental pollution have largely obliged electrical electronic waste (e-waste) should be tackled in an environmentally sound manner. Recycling process development is regarded as the most effective fundamental to solve e-waste problem. Based global achievements related recycling past 15 years, we first propose a theory design process, including measuring recyclability selection of process. And summarize indicators tools terms dimension,...
We employed a scanning probe-based lithography process on single-crystalline Si(100), Si(110), and Si(111) surfaces studied the effects of crystallographic surface structures mechanochemical etching silicon in liquid water. The facet angle rate were different from those purely chemical process. In water, shape mechanochemically etched nanochannel appeared to be governed by thermodynamics surface, rather than stress distribution. Analyzing etch with mechanically assisted Arrhenius-type...
Mechanochemical reactions between adsorbate molecules sheared at tribological interfaces can induce association of adsorbed molecules, forming oligomeric and polymeric products often called tribopolymers). This study revealed the role or effect surface chemistry solid substrate in mechanochemical polymerization reactions. As a model reactant, α-pinene was chosen because it known to readily form tribopolymers sliding interface stainless steel under vapor-phase lubrication conditions. Eight...
