Large-area catalytic thin films offer great potential for green technology applications in order to save energy, combat pollution, and reduce global warming. These films, either embedded with nanoparticles, shaped with nanostructuring techniques, hybridized with other systems, or functionalized with bionanotechnological methods, can include many different surface properties including photocatalytic, antifouling, abrasion resistant and mechanically resistive, self-cleaning, antibacterial, hydrophobic, and oleophobic features. Thus, surface functionalization with such advanced structuring methods is of significance to increase the performance and wide usage of large-area thin film coatings specifically for environmental remediation. In this review, we focus on methods to increase the efficiency of catalytic reactions in thin film and hence improve the performance in relevant applications while eliminating high cost with the purpose of widespread usage. However, we also include the most recent hybrid architectures, which have potential to make a transformational change in surface applications as soon as high quality and large area production techniques are available. Hence, we present and discuss research studies regarding both organic and inorganic methods that are used to structure thin films that have potential for large-area and eco-friendly coatings.

The application of green technologies can reduce environmental hazards and promote sustainability. The connotation of green technology innovation has two main aspects: the first aspect is the generation of green technology from nothing to something, and the other aspect is the improvement and upgrading of existing green technology; these two aspects are related. However, from the existing research, there are relatively few studies on the process of green technology innovation from these two aspects at the same time. If green technology is not studied from this perspective, the evolutionary process and influencing factors of green technology from generation to development cannot be clarified, which is not conducive to the development of green technology and the realization of the goal of environmental friendliness. Research considers the green innovation process from R&D to upgrading linkages and analyses the roles of government departments, green technology R&D institutions, and green technology application enterprises in green technology innovation. In addition, the green technology application enterprises are considered to promote technology enhancement through technology application feedback with green technology R&D institutions. The evolutionary game model of three subjects was established, the strategic evolution process of different subjects was analyzed, the influence of each element on the strategic choice of different subjects was explored, and the stability analysis of strategic choice was conducted using simulation software. The study shows the following: (1) The greater the government’s punishment and support to green technology R&D institutions, the more favorable it is for green technology R&D institutions to carry out green technology R&D. (2) In green technology applications, if the government has no direct interest relationship with green technology application enterprises, the enterprises will choose negative response behavior. (3) The greater the technology enhancement gains of green technology R&D institutions and the greater the feedback gains of technology applications actively carried out by enterprises in response to the government’s call, the more the government departments tend to support green technology R&D.

With an increase of Green Technology applications, Photovoltaic have emerged as the most appropriate solution for electricity generation purposes. However, due to variable temperature and irradiance, under the partial or shaded conditions Maximum Power Point Tracking is needed to determine highest efficiency of the system. The paper describes dynamic modeling and control of variable temperature and irradiance on solar panel in SIMULINK-MATLAB environment. The implementation of Buck Converter is used for power switching and impedance matching on connecting the panel to the load. The effectiveness of the model, with enhanced efficiency through voltage stabilization, is performed using Proportional-Integral-Derivative and Fuzzy-Logic-Controllers. A comparative study is made for PID and FLC on the basis of outputs to deal with online set point variations. FLC gives closer results to Standard Test Conditions when compared with PID. The Fuzzy system developed, using tested membership functions serve as a platform for sustainable standalone and grid-based applications using distributed MPPT.   With an increase of Green Technology applications, Photovoltaic have emerged as the most appropriate solution for electricity generation purposes.

Although sustainability and technology are two major concerns in the lodging industry, sustainability applications and practices are quite new and in need of more research. This study was conducted to examine and understand hotel guests' perceptions of green technology applications and practices. Data were collected in 2018 from 210 respondents via an online survey. The Technology Acceptance Model was applied to examine how ease of use and usefulness of green technology applications and practices can influence guests' booking decisions. The results showed significant positive correlations between behavioral belief and usefulness and between usefulness and intention to use green technology applications and practices. However, behavioral belief and ease of use were not correlated, nor were ease of use and intention to adopt green technology. These results demonstrate that guests do believe in the important role of green technology in sustainability and they intend to book hotels that adopt this technology.

Technology applications in the concrete mix is ??growing very rapidly in this modern era to obtain concrete results with characteristics that are environmentally friendly and non-toxic. Bioconc is innovation in developing green technology with the insertion of a micro-gap or slit gradation mycelia microbe as a micro-filter to mengoptimalkanatau reduce the amount of cement concrete on the concrete mix in total will increase the efficiency in the concrete and reduce the material components of the most expensive in the concrete, the cement. in job mix additive Bioconc require R%, ie a reduction factor of cement that will determine how the dose of cement and dose additive Bioconc, and therefore to seek R% require some percentage of reduction factor of cement optimum ranging from the concrete Normal, 5%, 10%, 15%, 20%, 25%, 30%, 35%.? + 31271x? - 4709x³ - 233.1x² + 79.66x + 22:18, concrete quality obtained from normal concrete with fc '= 20 MPa generate optimum value reduction of cement amounted to 28.869%.
