Chemtrails Exposed
Chemtrails Exposed: A New Manhattan Project pulls back the curtain on one of the most controversial topics of our time--geoengineering and weather control. Through meticulous research and hard evidence, this book reveals how powerful global elites, shadowed institutions, and scientific gatekeepers have shaped the skies above us. Every applicable government agency and almost all mainstream media outlets claim that chemtrails are merely a "conspiracy theory." They say that the lines in the sky are harmless condensation trails and that jet aircraft have always produced emissions that can linger in the sky for hours as they spread out and form a hazy cloud-cover. They say that anybody who asserts that aircraft are routinely spraying us with toxic materials is crazy. If this is so, then why are we consistently seeing anomalously high levels of toxins in rainwater as well as in ambient air samples? Why are there hundreds of scientists and scores of scientific organizations advocating for spraying substances from aircraft and calling it "geoengineering?" Why is there a world-famous PhD scientist who has, in a long series of peer-reviewed journal articles, made the case for chemtrails and shown detailed evidence of their harmful effects? How do we have whistleblowers from the Air Force and the Environmental Protection Agency? How is it that there is a huge, detailed, chronologically consistent body of evidence supporting the notion that the lines in the sky are part of a global weather modification project with roots going back over 100 years? This is just scratching the surface. This book presents the evidence that the government and the mainstream media ignore. This book provides the evidence that what is commonly referred to today as "geoengineering" is an incredibly large, ongoing operation involving the open-air spraying of tens of thousands of megatons of toxic waste ANNUALLY from high-flying jet aircraft. Believe it or not, the media and the government have not been telling the truth. If you seek truth behind the haze, Chemtrails Exposed is your definitive guide to the unseen forces shaping our world's climate, science, and future.

Plasmonic Photocatalysts
Plasmonic properties of noble metals (NMs) have been used to activate wide-band-gap semiconductors. Although plasmonic properties were observed more than a century ago, scientifically explained, ca., 40 years ago, and have been commercially used in many fields, the examination of their application for photocatalysis is quite new. Despite the novelty of plasmonic photocatalysis, many studies have already been performed to improve photocatalytic activity and stability and to clarify the mechanism. Although desirable photoabsorption properties of plasmonic photocatalysts can be easily achieved by the preparation of nanoparticles of different sizes and shapes, their photocatalytic activities under vis are still low, and thus must be improved for possible commercialization. Therefore, various studies have been performed to obtain stable and highly active materials. Moreover, the mechanism of plasmonic photocatalysis has not been clarified yet. It is thought that the mechanism depends directly on the morphology of plasmonic photocatalysts and reaction conditions. Despite the novelty, plasmonic photocatalysts have already proven promising activity for environmental purification, solar energy conversion, and organic compound synthesis. This Special Issue describes the significant and increasing role of plasmonic materials in catalysis.
Corrosion and Mechanical Behavior of Metal Materials (2nd Edition)
Dear Colleagues, Many structural metal materials work under the coupling condition of the load and corrosion environment. Therefore, it is necessary to study the corrosion and mechanical behavior of metal structural materials. The corrosion behaviors of metals under the coupling condition of the mechanics and corrosion environment mainly include stress corrosion cracking, hydrogen-induced cracking, corrosion fatigue, erosion corrosion, wear corrosion, etc. From the macroscopic or microscopic point of view, these corrosion damages all involve the fracture process, and fractures are caused by environmental factors, also known as environmental fractures. Thus, this Special Issue, the second volume of "Corrosion and Mechanical Behavior of Metal Materials", will still focus on the environmental fracture behavior of metal materials. We present the topic, including but not limited to experimental, computational, or theoretical studies on the environmental corrosion fracture of high-strength metal materials.
Theme Issue in Memory to Prof. Jiro Tsuji (1927-2022)
This reprint is dedicated to Professor Jiro Tsuji, who passed away on April 1st, 2022. He pioneered the discovery of transition metal-catalyzed reactions and showed the general idea of developing these reactions in organic synthesis.

Advances in Measurement and Data Analysis of Surfaces with Functionalized Coatings
This Special Issue emphasizes the functional importance of topography in exhaustive surface exploration. Since the precision of small-scale surface data evaluation depends on the accuracy of the topography analysis, a comprehensive description of the measured roughness details influences the final rate of surface performances. The surface topography affects many material layer properties, from tribology, adhesion, and fatigue to some more sophisticated ones. Requirements from the industry also increase the accuracy in the surface evaluation with simultaneous decreasing of costs in the process control. Reducing the costs of qualified surface topography description processes enlarged the request from the detailed but fast methods of data measurement and study. Using sophisticated techniques involves mindful and skilled users. Therefore, the whole surface topography evaluation method relies on many factors. This Special Issue aims to provide some detailed information on how to be rewarded for false methods of surface topography inspection. A wide range of the presented surface topography results, including all of the chapters listed, might be classified as beneficial in many surface metrology issues addressed.
