The aim of this paper is to solve the toxic and harmful problems caused by traditional volatile corrosion inhibitor (VCI) and to analyze the effect of the layered structure on the enhancement of the volatile corrosion inhibition prevention performance of amino acids.

The carbon dots-montmorillonite (DMT) hybrid material is prepared via hydrothermal process. The effect of the DMT-modified alanine as VCI for mild steel is investigated by volatile inhibition sieve test, volatile corrosion inhibition ability test, electrochemical measurement and surface analysis technology. It demonstrates that the DMT hybrid materials can improve the ability of alanine to protect mild steel against atmospheric corrosion effectively. The presence of carbon dots enlarges the interlamellar spacing of montmorillonite and allows better dispersion of alanine. The DMT-modified alanine has higher volatilization ability and an excellent corrosion inhibition of 85.3% for mild steel.

The DMT hybrid material provides a good template for the distribution of VCI, which can effectively improve the vapor-phase antirust property of VCI.

The increased volatilization rate also means increased VCI consumption and higher costs.

Provides a new way of thinking to replace the traditional toxic and harmful VCI.

For the first time, amino acids are combined with nano laminar structures, which are used to solve the problem of difficult volatilization of amino acids.

The process of chronic pain (CP) and strategies is to improve the patient’s health and well-being. CP is a frequent medical problem that presents a major challenge to healthcare providers because of its complex natural history, imprecise aetiology, and inadequate response to pharmacological treatment. Although different definitions exist it is widely accepted that CP is an ongoing pain that lasts more than 3 months or that persists longer than the reasonably expected healing time for the involved tissues. Also, it is acknowledged that its treatment is much different than the treatment for acute pain. When addressing a person with CP, one should always keep in mind that pain is much more about the individual than the underlying medical condition. Every person is different, and healthcare providers should take a tailor-made approach to managing their pain. This is the only way to ensure good results in pain treatment. Treatment goals should be discussed and adapted to the patient profile. It is fundamental to have clear goals from the beginning and to ensure these are realistic, individualized, and measurable. Effective treatment for CP is only achieved through a holistic framework in which the patient’s well-being is the first concern and an interdisciplinary and societal approach is implemented from the first day.

This paper aims to review 68 archival studies on the impact of audit committees (ACs) on firms’ consequences [(non)financial reporting, performance and audit quality] in European firms.

Applying a stakeholder agency-theoretical framework, the author differentiates between three categories of AC variables: presence; composition; and resources, incentives and diligence.

The author finds that AC composition, (non)financial reporting and audit quality are dominant in the literature review. Other inputs or outputs are either too low in amount or yielded heterogeneous results, hindering clear tendencies. However, there are indications that financial expertise is positively related to financial reporting and audit quality, in line with agency theory and European regulatory assumptions.

In the discussion of potential future research, the author emphasizes, among others, the need for the recognition of innovative and sustainable AC variables, inclusion of moderator and especially mediator variables and reaction to endogeneity concerns by advanced regression models.

As the European Commission currently discusses extended regulations on AC duties and composition, this literature review highlights the huge impact of financial expertise on financial reporting and audit quality. In view of the increased monitoring duties of sustainability reporting, both business practices and regulatory bodies should increase the sustainability expertise of ACs.

This analysis makes useful contributions to prior research by focusing on attributes of AC and their impact on firms’ outputs in the European capital market, based on a differentiation between mandatory one-tier/two-tier systems and the choice model. The findings support the promotion of European evidence-based regulations, such as the Corporate Sustainability Reporting Directive and the Corporate Sustainability Due Diligence Directive.

The purpose of this study is to analyse Benidorm, San Sebastián, Gijón, Málaga, Tenerife Island and Santander smart tourist destinations (STDs) as a touristic model and example to follow by other destinations in Spain and all over the world.

To fulfil the stated objective, this study follows several phases that introduce and classify a set of measures implemented by the six Spanish smart destinations to be designed as a STD.

Findings suggest that being a STD requires a high cost, and this is only accessible to big destinations with enough resources. Of the 50 Spanish provinces, eight are STDs, and these are localised in coastal areas. Obviously, this challenge is not within the reach of any Spanish city. Moreover, findings of the current study prove that the six Spanish smart destinations have a good air accessibility through their six airports, but the accessibility in a STD is not just physical; this must provide digital accessibility to tourists through destination marketing organisation’s website and app that will supply them with information on a wide range of services, including accommodations, tourist attractions, restaurants, public transport, museums and monuments’ locations, amongst many others.

From a resident point of view, a STD cannot be only focused on a technological and tourism context; a STD also requires knowing and meeting the needs of local residents and having a voice in decision-making processes. Hence, this study shows a new perspective on STDs that will benefit the literature on STDs.
