Electrochemical oxygen reduction reaction (ORR) is at the heart in many sustainable energy conversion technologies such as rechargeable fuel cells and metal-air batteries. Currently, various noble/transition metal-based materials have been developed as catalysts for boosting their catalytic performances. Among them, single-atom catalysts (SACs) have received increasing interest as promising electrocatalysts

Sustained gene delivery by biocompatible materials represents a novel strategy for enhancing bone regeneration while providing protection against the damage of host immune response. However, compared with liposome-based vector, development of multifunctional biodegradable biocompatible biomaterials for in vivo efficient miRNA delivery is still a challenge in bone regeneration. Here, we developed an

Supported amine sorbents are extensively studied in literature due to their moisture tolerating abilities. Most of the work with this group of adsorbents pertain to experimental studies on adsorption capacity, kinetics, and stability tests on powdered sorbents. Only a handful of published studies have carried out thermodynamic assessment and process modelling to evaluate the performance of supported

Owing to their unique structural and electronic characteristics, MXenes are considered to be the most potential anode materials for Li-ion capacitors (LICs). However, the stacking of layers, which would inevitably lead to the reduction of active sites and the sluggish lithiation kinetics, highly inhibits their electrochemical performance. Herein, to overcome the stacking and simultaneously improve

Mesenchymal stem cell (MSC)-derived exosomes have shown potential as an effective therapeutic tool for repairing bone defects. In this study, we demonstrate that silk fibroin (SF) 3D-scaffolds enriched with MSC-derived exosomes successfully enhance bone regeneration in critical-sized rat calvarial defect areas. The exosomes coated on the SF scaffolds were not subjected to any chemical treatments or

Precisely striking the bacterially infected site and avoiding damage to healthy tissues is vital for bacterial infection therapy. Herein, an intelligent antibacterial platform that triggers the aggregation of gold nanoparticles (AuNPs) on bacterial surface based on the acidic environment of bacterial infection was developed. Also, the AuNPs functionalized with an acidity-triggered moiety (Pep-DA) exhibited

A continuous flow packed bed reactor system was developed for the asymmetric reductive amination of 5-methyl-2-hexanone with a chimeric amine dehydrogenase (AmDH) and the formate dehydrogenase (FDH) from Candida boidinii. Both enzymes were co-immobilized onto the Nuvia® IMAC resin from Bio-Rad which employs the well-established binding chemistry between 6xHis-tagged proteins and immobilized Ni2+. Binding

Chemical looping with oxygen uncoupling (CLOU) and chemical looping air separation (CLAS) are novel and potentially promising processes for the combustion of solid fuels (e.g. biomass) for power generation with inherent CO2 capture. Redox-experiments at 850–950 °C confirmed that copper manganese spinel oxides are promising oxygen carriers for these processes, as they combine a relatively high O2 release

Polysiloxane is one of the most favorite polymeric materials used in the emerging field of passive surface icephobicity; This is due to its tailorable softness, hydrophobicity, and relatively high durability. Given the state-of-the-art ice adhesion strength of polysiloxane surfaces has reached a threshold below 1 kPa, a timely survey on the published polysiloxane icephobic surfaces can serve as a valuable

In this work, clinochrysotile-like magnesium silicate nanotubes (MS-TNs) were fabricated by a hydrothermal method and then modified with dodecyltrimethoxysilane (DTMS) for the first time to act as a superhydrophobic material (MS-TNs/DTMS), whilst the MS-TNs was used as a nanocontainer to load a corrosion inhibitor 2-mercaptabenzimidazole (2-MBI). Taking the advantage of epoxy resin as a coating matrix

Anaerobic digestion has historically shown critical operational limitations for treating industrial wastewater. Our work aims to evaluate the resilience capacity of a novel concept so-called microbial electrochemical fluidized bed reactor (ME-FBR) for treating real brewery wastewater under continuous operation mode over one year period. All assays were run in parallel using a conventional anaerobic

The thermochemical splitting of CO2 into CO based on redox reaction demonstrates great promising for clean energy production. However, the redox material inevitably suffers from high-temperature sintering, leading to an increased ion diffusion barrier that deactivates the bulk phase. In this study, a distinct strategy is demonstrated to neutralize the adverse effect of sintering by engineering a non-stoichiometric

Phosphotungstic acid (H3PW12O40, HPW) exhibits a good desulfurization performance towards the oxidative desulfurization (ODS) of oil-derived fuels. However, it presents two drawbacks: a small specific surface area and poor recovery. In this work, HPW was loaded on the support UiO-66, with a stable structure and large specific surface area, and a family of [email protected] catalysts was prepared. Based

Fast pyrolysis is a promising way to convert biomass waste into value-added chemicals, but current approaches give poor yield and selectivity for the desired chemicals (e.g. anhydrosugars). This study reported a novel two-staged controllable pyrolysis process consisting of torrefaction of H2SO4-impregnated eucalyptus waste and subsequent fast pyrolysis for achieving directional valorization of eucalyptus
