Pandey, Optimization and comparative evaluation of optical and photocatalytic properties of TiO 2 thin films prepared via sol-gel method, Journal of Saudi Chemical Society (2015), doi: http://dx. Abstract:TiO 2 thin films were fabricated with optimization of the synthesis parameters for efficient photocatalysis. The films were sculptured from gels obtained from Ti(O i Pr) 4 and Ti(OBu s ) 4 via spin coating at different rotation speed ranging from 1000 rpm to 3000 rpm. Thicknesses of the films were in the range of ≈ 112 nm to ≈ 160 nm. The X-ray diffractograms showed a phase transformation from anatase to rutile along with increase in average crystallite size from 11 nm to 18 nm with decrease in thickness of the films.Refractive index (n) values of the films were in the range of 2.50 to 3.45 while extinction coefficient (k) values ranged from 0.090 to 0.860. These films were transparent with high transmittance (T ≤ 95%) in the visible region. The optical band gaps for films were calculated to be in the range of 3.00 eV to 3.95 eV. Photocatalytic degradations of methylene blue by the fabricated TiO 2 thin films has also been investigated.Introduction:

“…A shielded enclosure will use a conductive material or a mesh to attenuate the propagation of electronic fields into the enclosure. Sufficient shielding (attenuation) of the enclosure is important to make it difficult to connect to the devices (wirelessly) and alter, delete data or add corrupt digital materials/data onto the devices [3], or to allow the devices to act remotely to perform such functions such as timer-based dialling of a detonator on an improvised explosive device.…”

Heaviside, in volume 1 of Electromagnetic theory , considered shielding of conducting materials in the form of attenuation. This treatment is still significant in the understanding of shielding effectiveness. He also considered propagation of electromagnetic waves in free-space. What Heaviside (1850–1925) could never have imagined is that 125 years later, there would be devices we know as mobile phones (or cell phones, handies, etc.) with capabilities beyond the dreams of the great science fiction writers of the day like H. G. Wells (1866–1949) or Jules Verne (1828–1905). More than this, that there would be a need for law enforcement agencies, among others, to use electromagnetically shielded enclosures to protect electronic equipment from communicating with the ‘outside world’. Nevertheless, Heaviside's work is still fundamental to the developments discussed here. This paper provides a review of Heaviside's view of shielding and propagation provided in volume 1 of Electromagnetic theory and develops that to the design of new experiments to test the shielding of these portable enclosures in a mode-stirred reverberation chamber, a test environment that relies entirely on reflections from conducting surfaces for its operation. This article is part of the theme issue ‘Celebrating 125 years of Oliver Heaviside's ‘Electromagnetic Theory’’.

“…For the purposes of this paper, a list of all the different types of born-digital carriers would only be limiting because a welldeveloped workflow should be able to process any type of born-digital carrier that the archivist encounters, providing the archivist has access to the right type of equipment. While handheld devices such as phones and tablets could eventually enter archives and would need further equipment and processes, these objects are not something archivists are currently receiving or expect to receive in the near future (Doherty 2016).…”

Digital forensics allows cultural heritage institutions to validate, preserve, and recover digital objects. This thesis discusses the development and implementation of a custom digital forensics workflow for the Archives of Ontario. The justifications for the workflow are based on research into digital forensics, authenticity, diplomatics, and digital preservation. The workflow seeks to clarify best-practice policies and procedures for using a Digital Intelligence Forensic Recover of Evidence Device (FRED), an out-of-the-box digital forensics hardware solution. The Archive procured a FRED tower requiring an implementation plan and overall strategy for its effective use. Presented in this paper is a workflow built specifically for the needs of the Archives as well as justifications for the processes proposed within the workflow. The BitCurator processing environment is addressed as an integral tool for implementation. Also discussed are modifications made to the Archive’s FRED tower to produce what I have called FrankenFRED.
