“…Silver ion (Ag + ) has reached wide utilization area from jewelry designing [14] to photography [15] and electronic industry [16] over the years due to its prominent characteristics such as high thermal [17] and electrical conductivity [18], contact resistance [19] etc. Furthermore, due to its high antibacterial [20] and antifungal characteristics [20,21], silver ion is frequently used in medical applications as well, such as production of bone prostheses [22], dental amalgams [23], and catheters [24].…”

B esides the knowledge that DNA is the primary hereditary molecule with possessing genetic code hidden in its double stranded helix form (B-form), an increasing number of evidence demonstrate that DNA, due to its non-canonical (non-B-form) structures, have regulatory functions on various cellular processes as well [1]. While duplex form of DNA is built up via Watson-Crick base pairing edges of nucleotide residues, some forms of the DNA are created by binding of auxiliary strands to a duplex DNA via Hoogsten base pairing edges of nucleotides [2,3]. In particular, triplex DNA forms have become one of the primary research areas due to the possibility of targeting regulatory regions of several oncogenes [2][3][4] and that their providing ease to manipulation due to exhibiting high stability in comparison to duplex forms [5].These triplex DNA forms could be created via binding of an auxiliary strand which is either rich in purine or pyrimidine, purine rich strand of the duplex DNA [6].

Modern forensics encounters new challenges and demands new analytical methods that would meet variety of prerequisites regarding their accuracy, rapidness, flexibility, and reliability. Vibrational spectroscopic methods, in particular near-infrared spectroscopy, offer such potential and meet an increasing interest in forensics for authentication of various documents. Pittcon 2020 Conference, which took place in Chicago, Illinois, included a Session dedicated to the role of novel tools of investigation in the forensics of tomorrow. This article summarizes and complements the presentation upon how the current state-of-the-art and future prospects of vibrational spectroscopic techniques fits into this role. The application of near-infrared spectroscopy, including the benefits stemming from using novel miniaturized portable instruments, Raman and surface-enhanced Raman scattering techniques, is discussed in detail in the present article.

“…These techniques are relatively simple and versatile tools for the textural examination and the petrographical/mineralogical composition of a range of building materials, such us stones, limes, mortars, tiles, bricks, glasses, metals, and wood. Confocal optical microscopy has, also, emerged as an in-depth morphometric tool and offers the possibility for the 3D reconstruction of the sample surface [ 8 ].…”

Scanning Microscopy Techniques as an Assessment Tool of Materials and Interventions for the Protection of Built Cultural Heritage

Scanning microscopy techniques have emerged as powerful scientific tools for analysing materials of architectural or archaeological interest, since the commercialization of the first scanning electron microscopy instrumentation in the early 60s. This study is aimed at reviewing and highlighting the significance of several scanning microscopy techniques employed in the protection of built heritage. The diffusion of scanning electron microscopy with energy-dispersive X-ray spectroscopy analysis (SEM-EDX) is proven to be the widest among the available scanning microscopy techniques, while transmission electron microscopy (TEM) applications are steadily present in the field of built heritage protection. The building material characterization, the weathering mechanism investigation, and the development of compatible and performing conservation materials are some major research areas where the application of the aforementioned techniques is discussed. The range of techniques, along with aspects of instrumentation and sample preparation are, also, considered.
