Catalytic upgrading of pyrolysis vapors from wheat straw over Na2CO3 impregnated γ-Al2O3 was studied as a promising route to biofuels. The Na species were homogenously distributed on the support and created a basicity of ∼0.02 mmol CO2/g catalyst, at 80% lower catalyst acidity. Analytical pyrolysis using a micro-pyrolyzer showed that Na-Al2O3 particularly decreased the yield of acids via ketonization

Fusarium crown and root rot is among the world's major agricultural diseases caused by Fusarium. oxysporum f. sp. radicis-lycopersici, which always resulted in serious damage to vegetable production worldwide. Pyraclostrobin is a broad-spectrum and highly effective fungicide with strong activity against F. oxysporum f. sp. radicis-lycopersici. However, the limited distribution of pyraclostrobin in

With the development of 3D printing technology, photo-curable resin can be used to fabricate bulk objects. However, photo-curable epoxy resin used in 3D printers are commonly considered as a stiff material which is fragile. In this study, a molecular designed core-shell particles (CSP) comprising epoxide groups are prepared to improve the toughness and interlayer bonding of stereolithography resin

The human skin tissues were full of elastic collagen networks to keep water, mechanical strength and capture tactile signals. Learn from this, it is highly desired to use natural biomaterials especially protein host materials to prepare artificial skin with excellent mechanical property, highly transparent and multi-sensing. In this work, we first demonstrate a natural silk fibroin (SF) membrane based

It will be interesting and yet challenging to develop a near-infrared (NIR) laser trigger phototheranostics agent for multimodal imaging guided synergistic phototherapy. In addition, the mechanisms of phototheranostics agent or in combination with NIR for tumor therapy remain unclear. Herein, we fabricate porous Co3O4 nanoplates (pCo3O4 NPs) using a hydrothermal process followed by a calcination treatment

Deep eutectic solvents (DESs) are generally used as attractive solvents or extractants rather than catalysts in the field of synthesis and separation. Herein, dual Brønsted acidic DESs were prepared by mixing sulfonated quaternary ammonium and oxalic acid as extractants and catalysts for deep oxidative desulfurization. Compared to the DESs with single acidic group, the dual acidic DESs exhibited much

Biochar was added into constructed wetlands (CWs) as an amendment to the main substrate (i.e., coarse gravel) for improving the removal efficiency of pollutants and mitigating greenhouse gas (GHG) emissions. Four types of mesocosm-scale CWs, i.e., unamended subsurface batch constructed wetland (SSBCWs) and surface batch CWs (SBCWs), and biochar-amended SSBCWs and SBCWs, were established in this study

Ni-rich layered oxides are potential cathode candidate’s materials for Li-ion batteries due to their low cost and high energy density. However, it is difficult to reproducibly prepare uniformly distributed element and well-controlled morphology of Ni-rich layered oxide particles. This study develops a continuous microfluidic reaction process to synthesize spherical carbonate precursors (Ni0.6Mn0.2Co0

This work reports the experimental conversion of oleic acid (OA) into methyl oleate via UiO-66 MOF catalyst. Strong focus is on the kinetic modeling: 67 models, based on elementary reaction steps for Eley-Rideal, Langmuir-Hinshelwood and Hattori kinetic mechanisms, are proposed. Via the application of initial reaction rate theory and nonisothermal kinetic modeling, one model adequately describes the

Bismuth vanadate (BiVO4) as a promising photoelectrode has been received an increasing attention for photoelectrochemical (PEC) water splitting. However, the severe surface charge recombination of BiVO4 still limited the PEC water splitting efficiency. Herein, a simple process is developed for preparing ternary spinel MCo2O4 (M = Mn, Zn) nanoparticles on the surface of BiVO4 photoelectrode as an efficient

Rationally constructing the electrode with the hierarchical structure, different components, and the flexibility is a promising approach to further improve the electrochemical properties and meet the demand for flexible electronic devices. In this paper, for the first time, hafnium carbide nanowires (HfCNWs) networks, with the metrics of large specific surface area, excellent conductivity, and chemical/physical
