The scenario of clean wines is rather articulated, and many consumers perceive diverse types of wines as a homogeneous category, not actually related with the true characteristics of the products. Additionally, most often, individuals turning to these wines are driven either by health concerns or environmental consciousness or by curiosity. The purpose of this study is to understand whether there are differences in monetary preferences for four distinct clean labels and to analyze the level of interest of diverse market segments of regular wine consumers for this specific category of wines.

This study applied a computer-assisted Web interviewing technique. A survey was administrated in mid-September 2021 by a professional panel provider to a quota-based sample (N = 1,113) of Italian regular wine consumers. Individual willingness-to-pay (WTP) for red wines carrying different claims (organic, natural, low-sulfites and no-additives) and a conventional counterpart were collected. Clean wines’ WTP were subsequently used for hierarchical clustering.

Among the clean labels presented, respondents reported a higher WTP for organic wine. Cluster analysis yielded three actionable segments: “Easygoing wine enjoyers” (63.7%), “Convenience drinkers” (13.4%) and “Clean wine passionate” (23%). The latter reveals high preferences for all the investigated clean wines.

Sociodemographics and wine-related characteristics of regular wine consumers particularly interested in clean wines are depicted in this study; further analysis should delve on the core drivers of individual preferences.

Wineries should consider the heterogeneous interest of regular wine consumers for clean wines, developing tailored strategies for specific market segments. Stakeholders interested in safeguarding consumers should carefully monitor the landscape of different clean claims entering the wine market.

To the best of the authors’ knowledge, no previous study has simultaneously analyzed regular wine consumers’ preferences for the four types of clean labels.

The throwing power of the acid copper plating process is affected by solution composition, organic additives, plating conditions and bath geometry. Recommendations for optimising these areas are given and production experiences reported.

Rheox, Inc., is a leading producer of rheological additives. The company's products are used in a wide variety of industries including those involved in the formulation and production of paints, resins, ink, adhesives and sealants.

The purpose of this paper is to examine the use of additives in formaldehyde‐free copper‐plating solutions with low reducing agent (RA) concentration to improve the start reaction of electroless copper deposition and to enable a copper‐plating process which is more environmentally friendly.

Different additives were investigated and their influence on the plating reaction and deposition rate was elucidated using several deposition trials.

On palladium‐activated base material, the additives reacted with the palladium and generated additional electrons in the initial phase of the deposition. Thus, the adequate supply of electrons from two sources (RA and additive) permits the deposition of a homogeneous and compact copper layer.

At the present time, formaldehyde is the established RA in the electroless copper metallization process used with plated through‐holes. Because of its environmental impact, there is a need to replace formaldehyde. In this investigation, the more environmentally friendly glyoxylic acid is used as an autocatalytic RA. However, glyoxylic acid is more expensive and causes undesirable side reactions. In order to keep process costs under control, the concentration of glyoxylic acid in the copper bath should be reduced without affecting the quality of the copper deposits.

Additives can compensate for the lower RA concentration, and thus the lack of essential electrons for the copper deposition.

As multifunctional additives, ZDDP, which provides excellent oxidation resistance and superior antiwear properties, has been used widely in lubricants, however, it shows oppositional effect with friction modifiers when used together. In this paper, an attempt is made to find a novel kind of borate ester which can be used as potential substitute for ZDDP.

A novel borate ester containing dialkylthiophosphate group was prepared and characterized. Its tribological properties as an additive in synthetic ester were evaluated using a four‐ball tribometer and antioxidative ability tested by pressurized differential scanning calorimetry (PDSC). Thermal degradation tests were conducted to identify its thermal stabilities using thermogravimetric analyzer (TGA). The worn surface of the steel ball was investigated by X‐ray photoelectron spectroscopy (XPS) and the antiwear mechanism of the additive was preliminarily discussed.

Results show the additive possesses outstanding loading‐carrying and friction‐reducing properties, compared with ZDDP, and can improve antiwear properties of the base oil dramatically. Moreover, it also has excellent antioxidation performance and thermal stability.

This paper provides a multifunctional ashless additive which possesses excellent tribological properties, and gives another selection for industrial applications in which ZDDP is needed.

The purpose of this paper is to solve the issue of via filling and pattern plating simultaneously by concentration optimization of accelerator and leveler in the electroplating bath.

This paper designs a series of experiments to verify the performance of pattern plating with the via filling plating formula. Then the compositions of electroplating solution are optimized to achieve via filling and pattern plating simultaneously. Finally, the mechanism of co-plating for via and line is discussed in brief.

To achieve excellent performance for via filling and pattern plating simultaneously, proportion of additives are comprehensively considered in optimization of electroplating process. Effects of additives on the via filling and pattern plating should be taken into consideration, especially in achieving flat lines.

This paper discusses the different effects of accelerator and leveler on the via filling and the pattern plating, respectively. The process of co-plating for the via and the line is presented. The superfilling of via and the flat line are simultaneously obtained with the optimized via filling formula.

The purpose of this paper was to examine the film-forming behaviour of simple compositions of polyalphaolefin (PAO) containing an oil-soluble polyalkylene glycol (OSP) alone, a zinc dialkyl dithiophosphate (ZDDP) alone and then combinations of an OSP and ZDDP.

A Mini-Traction Machine with Spacer Layer Imaging technology was used to evaluate friction and film formation under a specific contact pressure, temperature and slide-to-roll ratio. Electrical contact resistance measurements were used to follow surface film formation.

The inclusion of an OSP to a PAO showed evidence of friction-reducing behaviour with low friction values over the rubbing cycle but no significant tribo-film build up. When a ZDDP (1 per cent) is added to the PAO, a thick tribo-film forms of about 100 nm. Addition of an OSP (10 per cent) shows this film still forms despite the OSP being a polar and surface-active additive.

The study was conducted under a narrow range of test conditions (e.g. temperature and contact pressure), and future work will focus on friction and film formation across a broader set of conditions.

Despite OSPs being polar and surface-active, they do not interfere with the ZDDP in forming an anti-wear film in a PAO and, therefore, their inherent properties of good deposit control could enhance the performance of modern lubricants.

OSPs offer promising benefits as friction reducers in PAOs. The research also suggests that OSPs do not negate the formation of ZDDP anti-wear tribo-films when in combination in a PAO.

The purpose of this paper is to investigate the inhibiting properties of four N‐3‐hydroxyl‐2‐naphthoyl hydrazone derivatives in 0.5 M H₂SO₄ solution and to study the mechanism of their action.

The effect of various parameters on the behavior of these inhibitors has been studied using the weight loss and polarization measurements.

The inhibiting action of the investigated compounds depends primarily on their concentration and molecular size. The compounds act as mixed type inhibitors and function via adsorption on carbon steel surface, which follows Frumkin adsorption isotherm. The addition of KI, KBr and KSCN to N‐3‐hydroxyl‐2‐naphthoyl hydrazone derivatives had a synergistic effect in enhancing the efficiency of corrosion inhibition.

This paper provides useful information regarding inhibition effect of N‐3‐hydroxyl‐2‐naphthoyl hydrazone derivatives and clarifies the role of the molecular structure and substituents on the inhibition efficiency of these investigated compounds on the corrosion of carbon steel in acidic solutions.

The purpose of this paper is to investigate the hydrolytic stability of several S‐hydroxyethyl N,N‐dialkyl dithiocarbamate‐derived borates SNB1, SNB2, and SNB3, to evaluate their tribological performances used as additives in polyalpha olefins (PAO), and to explore the tribochemical action mechanism.

First, the three additives are synthesized and characterized. Second, the hydrolytic stabilities of the three compounds are investigated. As the third step, they are, respectively, added to PAO and a series of samples with different concentrations of the additives in PAO are prepared, respectively. Their tribological properties are evaluated with two types of four‐ball machines, and then the wear scars were observed using a JSM‐5600LV scanning electron microscope. Finally, the elements on the worn surface are analyzed with a X‐ray photoelectron spectroscope (XPS).

The three novel compounds possess relatively good hydrolytic stabilities, excellent anti‐wear (AW) performances, friction reduction properties, and load‐carrying capacity. There is an optimum concentration of each of the three additives for their AW properties. According to the XPS analytical results, a boundary lubrication protective film has formed during friction consisting of FeSO₄ film, Fe₂O₃ film, and the complicated adsorption film composed of N‐containing organic compounds. In the protective films, a large quantity of compounds containing element B is not found.

The antioxidation performances and the anticorrosion properties are not estimated.

This paper aims to report on the synthesis and characterisation of new flame retardants and anticorrosive additives based on Schiff’s base compounds, which were added physically to organic coating.

Flame retardants are incorporated into polymeric materials either as additives or as reactive materials. Additive-type flame retardants are widely used by incorporating into polymeric materials by physical means. In this research, Schiff’s base (azomethine) compounds are added physically to alkyd paint as flame-retardant additives. Elemental analysis, infrared spectroscopy and proton nuclear magnetic resonance spectroscopy were used to characterise the structure of the prepared Schiff’s base compounds. Thermal gravimetric analysis was used to evaluate their thermal stability. Experimental coatings were manufactured on a laboratory scale, and then applied by brush on wood and steel panels.

Results of an oxygen index value indicated that alkyd paints containing Schiff’s base compounds as additives exhibit very good flame-retardant effects. Also the physical, mechanical and corrosion resistance properties were studied to evaluate the drawbacks of the additives. The additives did not affect the flexibility of the paint formula. The gloss and the impact strength were decreased by the additives, but the hardness, adhesion and corrosion resistance were significantly improved by these additives.

Alkyd resins are the most extensively used synthetic polymers in the coating industry. Nitrogen compounds are a small but rapidly growing group of flame retardants which are in the focus of public interest concerning environment-friendly flame retardants. So, the focus of this study is on Schiff’s base compounds as flame retardants and anticorrosive additives for alkyd resins to assess their applicability.

Schiff’s base compounds can be used as new additives in paint formulations to improve the flame-retardant and corrosion properties.

In recent years, there has been considerable interest in the nitrogen-based family of materials because they not only have a wide range of thermal and chemical stabilities, but can also provide improved thermal and flame-retardant properties to polymers. The present paper reports on the synthesis and characterisation of Schiff’s base compounds and their performance in alkyd resin coatings.
