An unprecedented polyoxoniobate (PONb) oligomer was obtained by addition of a methylene blue (MB) dye solution over the PONb solution formed a blue nanogel that was converted into a stable blue solid through a lyophilization process. The new solid composite, so-called “blue polyoxoniobate” (blue-PONb), presents a two-dimensional (2D) morphology with electrochemical performance that stand out among

As a new method of alloying, entropy engineering has proven to be an effective strategy to decrease the lattice thermal conductivity (κL). However, the majority of entropy engineering applications of half-Heusler alloys (HHs) are suboptimal. The poor Seebeck coefficients (S) and obscure underlying electron and phonon transport mechanisms of medium- and high-entropy HHs hinder the further optimization

Aqueous zinc ion batteries (AZIBs) have received extensive attention and study owing to environmental protection and intrinsic safety, in which ammonium vanadate (NH4V4O10) with possessing stable bi-layered structure and high theoretical quality capacity is regarded as a potential cathode material. Nevertheless, the excessive ammonium ions located in the interlayer largely limit the Zn2+ diffusion

Rational manipulation of low dimensional composite materials with tunable phase hybridization and hierarchical structure is evolving as a promising strategy to boost electromagnetic (EM) wave absorption performance. Herein, a cation-π interaction-driven assembly and carbothermic reduction strategy is proposed to construct the hierarchical 0D core-shell embedded 1D reduced graphene oxide (rGO) scroll

Remediation of wastewater with solid waste-based adsorbents is of great environmental significance, but most current waste-based adsorbents suffer from low efficiency. In this work, aminated waste paper (WP-NH2) membrane is successfully prepared by oxidation of various types of waste paper followed by grafting and crosslinking polyethyleneimine (PEI). WP-NH2 shows extremely high adsorption for various

In this study, a reticulated ceramic photocatalyst was developed to conduct the photocatalytic oxidation of gaseous toluene at high concentration. Toluene was used as a target pollutant to be degraded mainly due to its high toxicity and health effect. It was aimed to prove the potential of reticulated ceramic material with open and interconnected porous structure, high mechanical property, high surface

A novel reduced graphene oxide grafted carbon fiber (rGO-CF) cathode for electro-Fenton was prepared using a simple thermal treatment method and applied to the degradation of tetramethyldecynediol (TMDD), a massively used non-ionic surfactant. Electrochemical characterization demonstrated that the new cathode possessed high electroactive surface area (1387.1 cm2 g-1), low electron-transfer resistance

The raceway dynamics and combustion by lateral injection of high-temperature gas into a packed bed of solid fuel are widely practised in various industries such as ironmaking blast furnace (BF), yet the particle-scale simulation and understanding were hindered by low resolution and huge computational cost. In this work, an advanced reactive computational fluid dynamics-discrete element method (rCFD-DEM)

Depolymerisation of lignin to well-identified aromatic chemicals has been recognized as one of the most promising ways to valorise lignin. Widely investigated hydrogenolysis and oxidative depolymerisation strategies selectively disrupt labile interunit C−O linkages (e.g., β−O−4 linkages) but are ineffective on the disruption of robust interunit C−C linkages (e.g., methylene linkages) in condensed technical

Photovoltaic technologies for indoor energy harvesting have attracted considerable attention because of the unique power requirements associated with the Internet of Things. However, intermittent power supplies, low light intensities, and security issues are barriers to the development of indoor photovoltaic technology. Herein, we demonstrate an all-solid-state photo-rechargeable battery system for

Electrode materials with hollow micro-nanostructure have exhibited exciting promise in the field of advanced energy storage devices. Herein, a template-free strategy based on the Kirkendall effect was presented to synthesize a self-supporting bimetallic selenide with hollow nanostructure as a cathode for an aqueous zinc-based battery (AZBB). This strategy discards the tedious template introduction

It is well known that a small amount of surfactant may significantly affect the flow stability in bubble columns, which cannot be interpreted by the slight variation of the liquid physical properties, e.g., surface tension, viscosity or density. The underlying mechanism is relevant to the interfacial dynamics due to surfactant concentration gradient. However, direct resolution of the micro-scale dynamics

Injuries to the cornea can cause corneal opacity or even blindness. Especially scald wounds and chemical burns to the cornea can usually lead to loss of corneal epithelium function and deep damage to the corneal stroma. Injectable hydrogel has been widely applied in corneal tissue engineering because it is easy to handle and can completely fill the defect area with minimally invasive surgical procedures

With the advent of an aging society and increasing concern for cardiovascular health, comfortable long-term electrocardiographic (ECG) monitoring systems in daily life are much in demand. If the system can give real-time feedback on cardiovascular status and offer timely personalized advice like doctors, it will be beneficial to promote cardiovascular health and alleviate the imbalance of medical resources

A novel three-dimensional electrokinetic remediation (3D EKR) system, with FeOx/granular activated carbon (GAC) composite constituting a third electrode was investigated for the removal of Cr from a real contaminated soil. Such third electrode particles were distributed evenly throughout the contaminated soil and their additional presence enabled the generation of a higher and more stable current density

The need to improve current wastewater treatments to ensure a clean and sustainable water supply is an unquestionable contemporary challenge. It is therefore essential to facilitate knowledge transfer between research institutions and the industry by developing novel technologies to a proof-of-concept stage, demonstrating both treatment efficiency and compliance with environmental criteria. This study

The preparation of mesoporous silica from solid waste is an effective method to realize high-value utilization of solid waste and reduce the synthesis cost of mesoporous silica. However, the silica derived from solid waste often suffers from small pore size and weak adsorption capacity. Besides, the traditional method of extracting silicon from solid waste requires high-temperature melting in the presence

In present work, graphitic carbon nitrite (g-CN) homojunction was synthesized and coated onto 3D-printed photoreactor for the removal of Rhodamine B (RhB) dye. The photocatalysis and adsorption experiments were investigated for 6 hours under visible light irradiation and in the dark, respectively. The experimental parameters were flow rate of dye solution (1.0 – 3.0 mL/min), initial dye concentration

MXenes, as attractive two-dimensional materials, have shown extraordinary potential for applications, however, their instability severely limits further research and applications on a large-scale and industrial level.
