Recovering low-temperature heat Low-temperature sources are both abundant and largely dissipated into the environment. Yu et al. discovered a way to boost concentration gradient in liquid thermogalvanic cell that allows be recovered. The authors added component boosts by forcing crystallization of electrolyte at cold end, these crystals then melt hot end. This process efficiency is potential method for recovering low-grade heat.

Viscoelasticity describes the ability of a material to possess both elasticity and viscosity. Viscoelastic materials, such as rubbers, limited operational temperature range (for example, for silicone rubber it is -55° 300°C), above which breaks down below undergoes glass transition hardens. We created viscoelastic composed from random network long interconnected carbon nanotubes that exhibited an -196° 1000°C. The storage loss moduli, frequency stability, reversible deformation level,...
Improving the accessibility of ions in electrodes electrochemical energy storage devices is vital for charge and rate performance. In particular, kinetics ion transport organic electrolytes slow, especially at low operating temperatures. Herein, we report a new type MXene-carbon nanotube (CNT) composite electrode that maximizes resulting exceptional performance The improved temperatures made possible by breaking conventional horizontal alignment two-dimensional layers MXene Ti3C2 using...
Ni/Li exchange (disordering) usually happens in layered Li(NixMnyCoz)O2 (NMC) materials and affects the performance of material lithium-ion batteries. Most previous studies attributed this phenomenon to similar size Ni2+ Li+, which implies that should be more favorable than Ni3+ located at Li 3b sites slab. However, theory cannot explain why Ni-rich NMC where most Ni cations are Ni3+, even frequently. Using extensive ab initio calculations combined with experiments, here we report a...
Alignment represents an important structural parameter of carbon nanotubes (CNTs) owing to their exceptionally high aspect ratio, one-dimensional property. In this paper, we demonstrate a general approach control the alignment few-walled CNT forests from nearly random ideally aligned by tailoring density active catalysts at catalyst formation stage, which can be experimentally achieved controlling forest mass density. Experimentally, found that and degree were inseparably linked because...
Abstract Converting low‐grade thermal energy with small temperature gradient into electricity is challenging due to the low efficiency and high cost. Here, a new type of thermal–electric nanogenerator reported that utilizes electrokinetic effect for effective harvesting energy. The based on an evaporation‐driven water flow in porous medium gradient. With piece carbon film deionized water, maximum open‐circuit voltage 0.89 V under difference 4.2 °C obtained, having corresponding...
Abstract Considerable attention has been drawn to tune the geometric and electronic structure of interfacial catalysts via modulating strong metal-support interactions (SMSI). Herein, we report construction a series TiO 2− x /Ni catalysts, where disordered overlayers immobilized onto surface Ni nanoparticles (~20 nm) are successfully engineered with SMSI effect. The optimal catalyst shows CO conversion ~19.8% in Fischer – Tropsch synthesis (FTS) process under atmospheric pressure at 220 °C....
Abstract Conventional adhesives show a decrease in the adhesion force with increasing temperature due to thermally induced viscoelastic thinning and/or structural decomposition. Here, we report counter-intuitive behaviour of carbon nanotube (CNT) dry that temperature-enhanced strength by over six-fold up 143 N cm −2 (4 mm × 4 mm), among strongest pure CNT adhesives, range from −196 1,000 °C. This unusual leads electrical and thermal transports, enabling adhesive for efficient management when...
Abstract Zero liquid discharge (ZLD), which maximizes water recovery and eliminates environmental impact, is an urgent wastewater management strategy for alleviating freshwater shortage. However, because of the high concentration salts broad‐spectrum foulants in wastewater, a huge challenge ZLD lack robust membrane‐based desalination technology that enables direct without costly pretreatment processes. Here, paradigm‐shift membrane distillation (MD) presented, wherein traditional hydrophobic...
The shuttle effect of polysulfide (Li2Sn, 2 < n ≤ 8) and the sluggish reaction kinetics seriously hinder development lithium–sulfur (Li–S) batteries. Regulating electronic structure substrate materials could be an effective strategy to further modulate surface adsorption interface electron transfer for advanced Li–S Herein, a cobalt-doped vanadium nitride (Co-VN) microflower hierarchical with 5% Co/V ratio was synthesized as material. Theoretical calculation indicated that energy Co-VN...
