This study was aimed at developing environmental friendly adhesion materials using alkali soluble resins (ASRs). Water-borne emulsion pressure-sensitive adhesives show good compatibility with different polymer emulsions, high solid contents, and good working property, thereby allowing adjustment of the extensive viscosity. On the other hand, it is not easily recyclable and its adhesion and water-resistance properties are not optimal. Herein, ASR was used as the polymeric surfactant. ASR presents good emulsion stabilization, high molecular weight, and solubility in alkali solutions. ASR contains both hydrophobic and hydrophilic groups, thereby reducing the surface tension of the aqueous phase stabilizing monomer droplet or polymer particles. Additionally, it can form aggregates as a result of inter- and intramolecular hydrophobic interactions. The large number of carboxyl groups of this resin stabilizes polymer particles by an electrostatic effect. The recycling and adhesion properties of this resin were assessed by using UTM, a weight method. Further properties of the resin were determined by DSC, GPC, and ETC.

Soil salinization severely restricts the growth and development of crops globally, especially in the northwest Loess Plateau, where apples constitute a pillar industry. Nanomaterials, leveraging their unique properties, can facilitate the transport of nutrients to crops, thereby enhancing plant growth and development under stress conditions. To investigate the effects of nano zinc oxide (ZnO NP) on the growth and physiological characteristics of apple self-rooted rootstock M9-T337 seedlings under saline alkali stress, one-year-old M9-T337 seedlings were used as experimental materials and ZnO NPs were used as donors for pot experiment.

The processing of beans begins with a particularly time-consuming procedure, the hydration of the seeds. Ultrasonic treatment (US) represents a potential environmentally friendly method for process acceleration, while near-infrared spectroscopy (NIR) is a proposedly suitable non-invasive monitoring tool to assess compositional changes. Our aim was to examine the hydration process of red kidney beans of varying sizes and origins.

Dissolution of a poorly soluble active pharmacological substance in a drug carrier usually requires advanced techniques and production equipment. The use of novel carriers such as microemulsions, vesicles, or nanocarriers might entail various limitations concerning production cost, formulation stability, or active substance capacity. In this paper, we present a novel fumed silica-based organogel as a low-cost, simple preparation drug or cosmetic carrier with interesting rheological properties and high solubilization capacity.

Background: Saline-alkali stress is a major factor limiting the growth of oats. Sugar is the primary carbon and energy source in plants which regulates plant development and growth by regulating enzyme activity and gene expression. Sucrose, glucose, and fructose are ubiquitous plant-soluble sugars that act as signalling molecules in the transcriptional regulation of various metabolic and defence-related genes.
