We report a reconstitution method which could provide consistent shade depth and add-on in wet-on-wet pad/batch dyeing and finishing. Textile wet processing involves many steps of wetting and drying. Eliminating some of them by the wet-on-wet process could save energy. For a continuous process, due to the fast fabric movement, a wet fabric also could enhance chemical penetration for the improvement of properties and savings on auxiliary chemicals. One common problem associated with wet-on-wet process is that after padding several hundred yards of yarns/fabrics, chemical add-on is considerably

In papermaking, the conventional way to add chemicals to the web is to dose them into the fiber stock and form the paper afterwards. However, in many cases, adding chemicals directly to the stock is challenging. For example, strength aids tend to increase flocculation in the stock, which limits the addition amounts of those aids. The need for better performance of paper (and paperboard) products has given rise to the need for functionalization of paper. Adding such functional chemicals to the stock is usually rather inefficient. Hence, novel methods are needed to add chemicals to the paper bul

In the present work, densification of synthesised hydroxyapatite (HA) bioceramic prepared via chemical precipitation method was investigated. HA samples was prepared by compaction at 200 MPa and sintered at temperatures ranging from 800°C to 1400°C. The results revealed that the HA phase was stable for up to sintering temperature of 1250°C. However, decomposition of HA was observed in samples sintered at 1300°C with the formation of tetra-calcium phosphate (TTCP) and CaO. Samples sintered above 1400°C were found to melt into glassy phases. The bulk density increases with increasing temperature

Abstract Dry abrasive blast is the most widely used surface preparation method in coating industries. However, dry blasting has several drawbacks − (1) dusting to cause environmental hazard and health concern, and (2) residual salt contamination remained. Residual salts are buried in the corrosion pits and difficult to clean off. The abrasive blasted steel surface will develop flash rust within a day in a 50% Relative Humidity atmosphere and just in a few hours in offshore saline environment.

Municipal solid waste is a multicomponent mixture, when it is burned, diverse group of substances with different physic-chemical properties produces into the exhaust gases: carbon monoxide, sulfur dioxide, nitrogen oxides, f

Abstract Intergranular stress corrosion cracking (IGSCC) in above-ground carbon steel pipelines has been identified as a distinct mode of failure, different from the typical neutral pH and high pH SCC observed in buried pipelines. This form of SCC occurs under specific conditions, including operating temperatures ranging from 70°C to 190°C, exposure to wet mineral wool insulation, and insulation installations dating from post-2003. The affected carbon steel grades have included API 5L or CSA Z245.1 with specified minimum yield strength (SMYS) of 52 ksi or higher, as well as A106 Gr B, A234 WPB

Abstract Thermal oxidation in sophisticated incineration systems has become the technically preferred method for permanent disposal of chemical wastes, medical wastes, and hazardous wastes. The waste streams processed in these incineration systems contain sulfur, chlorine, fluorine, bromine, iodine, nitrogen, and phosphorus compounds. After combustion, they all form corrosive acidic liquids when absorbed in water. The resulting solutions can cause severe corrosion problems with most common metals. Upon initial gas contact with the scrubbing liquid, the pH can precipitously drop to less than ze

Abstract A method has been developed for creating diamond-like carbon (DLC) coatings on the interior surfaces of pipes. Newer formulations of DLC coatings have shown resistance to chemical attack in high temperature, high pressure autoclaves tests simulating sour production environments even when the coatings are deliberately mechanically damaged prior to testing. These coating have also been shown to be highly abrasion resistant in standard dry and wet abrasion tests. Thus, DLC coatings may significantly extend component life in abrasive hot sour applications in the oil and gas industry.

Abstract The cost of corrosion to the oil industry was estimated at more than 800 million dollars in 1983. At that time, oil companies were spending more than 50 million dollars per year on chemical inhibitors to control corrosion. Nearly all corrosion in gas wells occurs in the water condensation zone. A computer model, known as DOWN*HOLE, has been developed which can predict the location of the water condensation zone in gas condensate wells. This paper outlines the method used to predict the water-wet zone and discusses potential uses of the program.

Grooving corrosion is a phenomenon by which the weld seam of electric resistance welded (ERW) pipe is preferentially attacked in wet natural gas environments containing CO,. The attack initiates as an aligned string of pits which grow and intersect, forming a round-bottomed groove of damage centered on the weld seam. The susceptibility of ERW pipe to this damage mechanism is known to be related to the chemical composition (particularly the sulfur content) of the pipe, the welding process employed, and the use of a post weld heat treatment. Of particular concern to the natural gas pipeline indu

We proposed to extend the QuEChERS approach to veterinary drugs and other contaminants, and conduct fast and ultra-fast analyses using novel 5MB-MS instrumentation, ideally with real samples.

Background to the topic: For food safety and security reasons, hundreds of pesticides, veterinary drugs, and environmental pollutants should be monitored in the food supply, but current methods are too time-consuming, laborious, and expensive. As a result, only a tiny fraction of the food is tested for a limited number of contaminants.

Preferential flow is the process whereby water and solutes move by preferred pathways. During preferential flow, local wetting fronts propagate to considerable depths in the soil profile, essentially bypassing the matrix pore space. Under such conditions classical methods, such as the convective-dispersive equation, for quantifying flow of water and solutes in uniform soils are not valid. This project set out to develop methods to predict fast and early breakthrough of solutes. To facilitate understanding of these processes, several field drainage studies were conducted in the United States an

Integrated pest management in modern crop protection may combine chemical and biological insecticides, particularly due to the risks to the environment and livestock arising from the massive use of non-selective chemicals. Thus, there is a need for safer alternatives, which target insects more specifically. Scorpions produce anti-insect selective polypeptide toxins that are biodegradable and non-toxic to warm-blooded animals. Therefore, integration of these substances into insect pest control strategies is of major importance. Moreover, clarification of the molecular basis of this selectivity

Postharvest treatment of garden strawberries and the development of effective storage methods are crucial to increase the shelf life and preserve its quality until consumption. Although some reviews on certain treatment technologies have been published, we have not found studies that considered and compared common and advanced methods of storing garden strawberries. Therefore, the goal of this study is to review modern postharvest methods of strawberry storage (Fragaria × ananassa Duch). The review includes reports published in English and Russian in 2014—2024.

Polymer flooding is one of the most promising EOR methods (Smalley et al. 2018). It is well known and has been used successfully (Pye 1964; Standnes & Skjevrak 2014; Sheng et al. 2015). From a technical perspective we recommend that polymer flooding should be considered as a viable EOR method on the Norwegian Continental Shelf for the following reasons: 1. More oil can be produced with less water injected; this is particularly important for the NCS which are currently producing more water than oil 2.

There is increased demand for high quality fruit produced and marketed with reduced chemical inputs to minimize toxic effects on human health and the environment. Granny Smith (GS) apple quality is reduced by two major physiological disorders, superficial scald and bitter pit (BP). These disorders cause great loss to apple growers worldwide. Superficial scald is commonly controlled by chemical treatments, mainly the antioxidant diphenylamine (DPA) and/or the ethylene action inhibitor, 1-methylcyclopropene (1–MCP). Both chemicals are ineffective in controlling bitter pit incidence. We proposed
