Abstract The heterogeneous base catalyst, γ‐Al 2 O 3 loaded with KOH and K (K/KOH/γ‐Al ) was first prepared used in the transesterification of rapeseed oil methanol to produce biodiesel. catalyst characterized by X‐ray diffraction, scanning electron microscopy, Brunauer–Emmett–Teller method, infrared spectroscopy photoelectron spectroscopy. It found that when is K, Al–O–K species produced, resulting an increase catalytic activity. impacts preparation conditions on activities K/KOH/γ‐Al were...
Ralstonia solanacearum (Rs) is a soilborne phytopathogen that causes bacterial wilt and substantial yield losses in many plants, such as tomatoes. A resistant tomato cultivar can recruit beneficial microbiome from soil to resist Rs. However, whether this recruitment inheritable parent progeny has not been determined.
A novel approach to mitigate the environmental concerns associated with cement industry is replace Portland low carbon alternative materials such as fly ash-based geopolymer cement. Hence, reactive MgO-activated low-calcium Class F ash was employed in comparison Na2SO4-activated stabilize a lacustrine soil reused potentially soft coastal reclamation projects and reinforced aggregates for anti-corrosion marine engineering. The microstructural strength properties were investigated series of...
Hydrogen embrittlement (HE) impairs the durability of aluminium (Al) alloys and hinders their use in a hydrogen economy1-3. Intermetallic compound particles Al can trap mitigate HE4, but these usually form low number density compared with conventional strengthening nanoprecipitates. Here we report size-sieved complex precipitation Sc-added Al-Mg to achieve high-density dispersion both fine Al3Sc nanoprecipitates situ formed core-shell Al3(Mg, Sc)2/Al3Sc nanophases high hydrogen-trapping...
Alkali-activated industrial by-products (granulated blast furnace slag, Class F fly ash) by traditional alkali activator (such as NaOH and Na2SiO3) serves a partial replacement for Portland cement in soil stabilization projects suffers from environmental technical problems. Reactive MgO – greener more practical alternative has recently emerged potential slag ash, but its micromechanisms of alkaline activation still need to be deeply investigated strength improvement soils. Hence, this study...
A combined soil bacterial and fungal community survey was conducted for a copper tailings dam in the Chinese Loess Plateau. We investigated seasonal differences composition function of microbial to examine key environmental factors influencing microorganisms during restorative ecological processes. Significant were found structure both communities. Bacterial abundance (Shannon index) measurements highest summer. Soil nitrite nitrogen (NO2−-N) dominant factor The significantly affected by...
Triaxial unloading creep tests of layered rock specimen Jinping II hydropower station were carried out using the testing machine; thus deformation curves under different confining pressures acquired. The test results showed that, in addition to obvious characteristics specimen, nonlinear accelerating emerged last stage stress condition, and whole presented typical three stages. On other hand, Burgers model constitutive equations three-dimensional state also deduced. Based on data, through...
The comprehensive impacts of biotic and abiotic factors on the natural regeneration Abies georgei var. smithii (Abies) forests in Tibet are not thoroughly understood. To address this gap, our study focused densities seedlings, saplings, small trees across 21 plots (each 20 m × m) along an elevation gradient from 3730 to 4330 Sygera Mountains Southeastern Tibet. We meticulously measured a suite 11 variables that describe stand structures ecological conditions. Through analyses using...
Natural disasters such as landslides often occur on soil slopes in seasonally frozen areas that undergo freeze‒thaw cycling. Ecological slope protection is an effective way to prevent disasters. To explore the change mechanical properties of under influence both root reinforcement and cycles its stability, Baijiabao landslide Three Gorges Reservoir area was taken example. The different confining pressures, vegetation coverages (VCs) numbers were studied via tests, triaxial compression wave...
In recent years, vegetation plays a key role in landslide stability under extreme rainfall the Three Gorges Reservoir area, so it is very important to identify mechanism of slope protection. This study takes wildcat area as research object, using indoor model test and building monitoring systems such stress field, displacement soil erosion, illustrate protective effect typical vegetation. Furthermore, Bermuda cover effectively reduces pore water pressure, displacement, turbidity. particular,...
