Technology transfer (TT) is a mechanism designed to accurately make knowledge, innovations, and advancements available to the general population. TT is conducted through scientific papers, educational and governmental initiatives, and the commercialization of technology. The TT process per se is complex, involving many stakeholders and factors that can impact implementation. Feasibility studies are needed to assess the types of technology that can be transferred, the economic options to be chosen, and to stimulate the receptive part, making understandable the whole transfer flow. Furthermore, TT involves a dynamic mechanism that has advanced with the development of technology, with different linear, non-linear, and alternative models being proposed and scientifically validated, and with the possibility of addressing different perceptions of the factors involved. The international TT level, as well as the level of innovation in the economic context, differs from nation to nation. The need for this paper is based on the lack of a comprehensive detailed presentation of the TT infrastructural concept, approached in a novel and in-depth way by assessing international TT, technology flow, technology distribution and expansion, collaborative networks, TT centers and TT models, regional operational programs etc., all of which are related to national/international legislation and sustainable development. The deficit of representation and implementation of this concept in Romania was also covered, the assessment providing the current status and suggesting the need to develop and optimize the implementation of TT in this country.

The problem of the environment in the inhabited area, in particular of the hygienic-sanitary comfort, are current topics of concern for the builders. The interest of the authors meets the requirements of the tenant. In general, it seems that the cause of the hygienic-sanitary discomfort of the inhabited environment would be the faulty execution of the construction or an inconsistent architectural conception; the current paper presents several factors that cause this discomfort, the tenant being just one of them. The result of faulty operation/utilization of living spaces is inadmissible for those who live there, both materially and with repercussions on their health. Additionally, this paper demonstrates the deficiency of the existing energy performance certificate. The results of our research offer real solutions in eliminating, solving, and correcting the hygienic-sanitary discomfort of the environment inside the buildings; this can be achieved by designing, executing and operating spaces correctly, adequately and optimally, ensuring a healthy environment. The authors propose to improve the norms of protection of the built environment, by modifying the related energy performance legislation/certificate; moreover, new and real practical solutions have been suggested by the authors for the prevention and remediation of hygienic-sanitary discomfort.

The unpleasant odor that appears in the industrial and adjacent waste processing areas is a permanent concern for the protection of the environment and, especially, for the quality of life. Among the many variants for removing substance traces, which give an unpleasant smell to the air, membrane-based methods or techniques are viable options. Their advantages consist of installation simplicity and scaling possibility, selectivity; moreover, the flows of odorous substances are direct, automation is complete by accessible operating parameters (pH, temperature, ionic strength), and the operation costs are low. The paper presents the process of obtaining membranes from cellulosic derivatives containing silver nanoparticles, using accessible raw materials (namely motion picture films from abandoned archives). The technique used for membrane preparation was the immersion precipitation for phase inversion of cellulosic polymer solutions in methylene chloride: methanol, 2:1 volume. The membranes obtained were morphologically and structurally characterized by scanning electron microscopy (SEM) and high resolution SEM (HR SEM), energy dispersive X-ray analysis (EDAX), Fourier transform infrared spectrometry (FTIR), thermal analysis (TG, ATD). Then, the membrane performance process (extraction efficiency and species flux) was determined using hydrogen sulfide (H₂S) and ethanethiol (C₂H₅SH) as target substances.

Significant environmental and social issues confront the textile and apparel industries, including resource depletion and excessive textile waste. Implementing circular economy principles is essential for the sustainability of this industry. The present paper is a bibliometric analysis study type designed to identify collaborative networks, prolific countries, journals, and influential articles pertaining to the implementation of the circular economy in the textile and apparel industries that may serve as a starting point for an in-depth understanding of the subject, facilitating the knowledge of essential bibliometric parameters for pre-publication phases. The data were extracted from the Web of Science and analyzed using both the Web of Science web interface and the VOSviewer software version 1.6.19. The bibliometric data were divided into two distinct periods to analyze the evolution of this subject over time: from 1975 to 2010 and from 2011 to 2023. In the first period, the most productive country was the United States, with 527 publications, accounting for 10.81% of the scientific output during that time. In the second period, China emerged as the most productive country, with 2478 published documents, constituting 18.44% of the total production in this period. During the first period, Istanbul Technical University was the most active institution, with 91 publications (1.87% of the total production), while in the second period the Indian Institute of Technology System was the most productive, with 265 documents (1.95%). These key findings demonstrate the textile industry’s commitment to sustainable and environmentally friendly practices. They also highlight the industry’s adoption of advanced technologies and its exploration of new research areas; but there is still room for improvement, which is why continuous research implemented through future research areas is essential.

Currently, setting the obligation to use respiratory protective equipment with a level of protection of at least FFP2 in public transport and commercial and shopping centers are considered within the European Union. Many new products appeared on the European market within these specifications, and many symbols have been used. The paper deals with the meaning of selected respiratory protection based on respirators symbols and markings (which appeared massively, especially after the pandemic situation in the spring of 2020), these symbols not being uniformly understood and well communicated. We also mention and discuss some of the problems related to setting the conditions of public procurement, which affect respirators. Thus, this review is an “informative guide” in facilitating the understanding and use of full knowledge of the most appropriate respiratory protective devices in various situations.
