Abstract:

<strong>Abstract</strong> One of the basic ingredients of modern soap making is synthetic alkali such as caustic soda or lye (NaOH). The utilization of plant-based alkalis to make soap has been compared to the use of synthetic caustic alkalis (sodium hydroxide). Synthetic alkalis cause significant adverse effects on the environment which may be drastically reduced by using plant-based alkalis.

Abstract:

Saline-alkali and drought stresses are one of the abiotic stress factors that limit the normal growth and development of plants. In this work, various agronomic indexes including growth physiology and yield attributes were studied under saline-alkali and drought stress treatments. It was found that the limit of plant growth and development caused by drought stress is much higher than that of saline-alkali stress (p < 0.01). Based on the comprehensive evaluation value (D value), under saline-alkali stress condition, 36 maize varieties could be divided into four groups by cluster analysis (CA

Abstract:

This paper presents the development and implementation of a fly-ash-based alkali-activated concrete mixture for use in precast, prestressed concrete beams. Alkali-activated concrete, which contains no portland cement and often incorporates recycled materials, offers an environmentally friendly alternative to conventional concrete. The study evaluated over 40 mortar mixtures to identify a design suitable for precasting plant production. Full-scale beams and mechanical property specimens were fabricated and tested, alongside comparable portland cement concrete specimens. Results showed that the

Hydrogen is considered a key energy carrier for which interest has grown over recent years. Chlor-alkali plants in the United States (U.S.) can potentially recover and supply the by-product hydrogen at scale. However, there is a scarcity of standard analysis for energy use and emissions associated with products from chlor-alkali plants owing to lack of data and variations in chlor-alkali plant technology and operation.

Saline–alkali stress is a significant abiotic stress that restricts plant growth globally. Basic region leucine zipper (bZIP) transcription factor proteins are widely involved in plants in response to abiotic stress such as saline–alkali stress. Based on transcriptome and quantitative real-time PCR (qRT-PCR), we found that the MhbZIP23 gene could respond to saline–alkali stress. Despite this discovery, the underlying mechanism by which the MhbZIP23 transcription factor responds to saline–alkaline stress remains unexplored.

Abstract:

Biochar and bioorganic fertilizers (BOF) that are used in agriculture can, both directly and indirectly, impact rhizosphere soil microorganisms. However, changes to the halophyte rhizosphere bacterial community after applying biochar and BOF to saline–alkali soil have not been thoroughly described. This study has investigated the bacterial communities of halophytes in saline–alkali soil through the addition of different biochar and BOF formulas using Illumina-based sequencing of the 16S rRNA gene fragment. B_BOF (biochar and BOF combined application) had the best effect, either by promoting th

Abstract:

Fuel gas cleaning is an important step in the development of coal-based combined cycle technologies. By integrating hot gas cleaning facilities in the combined cycle power plant, higher operating temperatures can be achieved. Research is being carried out at the Institute of Ferrous Metallurgy, Technical University of Aachen, to develop a process for gas cleaning at temperatures above 1300°C using a venturi scrubber with molten slags as sorbents. This process offers simultaneous removal of particulate matter and alkali vapours in the gas stream. The present paper deals with the particulate rem

Abstract:

Alkali stress, a type of abiotic stress, severely inhibits plant growth. Only a few studies have investigated the mechanism underlying the transcriptional-level response of Morella cerifera to saline-alkali stress. Based on RNA-seq technology, gene expression differences in the fibrous roots of M. cerifera seedlings exposed to low- and high-concentration alkali stress (LAS and HAS, respectively) were investigated, and the corresponding 1312 and 1532 alkali stress-responsive genes were identified, respectively. According to gene set enrichment analysis, 65 gene sets were significantly enriched.

Sorghum (Sorghum bicolor) is the fifth most important cereal crop in the world. It is an annual C4 crop due to its high biomass and wide usage, and has a strong resistance to stress. Obviously, there are many benefits of planting sorghum on marginal soils such as saline-alkali land. Although it is known that abscisic acid (ABA) is involved in plant abiotic stress responses, there are few reports on sorghum. Here, we obtained RNA-seq data, which showed gene expression at the genome-wide level under saline-alkali stress. The genes related to ABA biosynthesis, catabolism, and signaling were ident

Soil salinization is a major factor that reduces crop yields. There are some plant growth-promoting rhizobacteria (PGPR) that can stimulate and enhance the salt tolerance of plants near their roots in saline–alkali environments. Currently, there is relatively little research on PGPR in rice saline–alkali tolerance. In the early stages of this study, a strain of Microbacterium ginsengiterrae S4 was screened that could enhance the growth of rice in a laboratory-simulated saline–alkali environment (100 mM NaCl, pH 8.5).

Abstract:

Fractal analysis is an effective tool to describe real world phenomena. Water evaporation from the soil surface under extreme climatic conditions, such as drought, causes salt to accumulate in the soil, resulting in soil salinization, which aggravates soil shrinkage, deformation, and cracking. Hippophae is an alkali tolerant plant that is widely grown in Northwest China. Laboratory drying shrinkage tests of saline−alkali soil samples with 0%, 0.5%, 1%, and 2% concentrations of hippophae roots were carried out to study the effect of hippophae roots on the evaporation and cracking of saline−alka
