Wastewater Treatment by Catalytic Wet Peroxidation
Nowadays, there is an increasing interest in the development of promising, efficient, and environmentally friendly wastewater treatment technologies. Among them are the advanced oxidation processes (AOPs), in particular, catalytic wet peroxidation (CWPO), assisted or not by radiation. One of the challenges for the industrial application of this process is the development of stable and efficient catalysts, without leaching of the metal to the aqueous phase during the treatment. Gold catalysts, in particular, have attracted much attention from researchers because they show these characteristics. Recently, numerous studies have been reported in the literature regarding the preparation of gold catalysts supported on various supports and testing their catalytic performance in the treatment of real wastewaters or model pollutants by CWPO. This review summarizes this research; the properties of such catalysts and their expected effects on the overall efficiency of the CWPO process, together with a description of the effect of operational variables (such as pH, temperature, oxidant concentration, catalyst, and gold content). In addition, an overview is given of the main technical issues of this process aiming at its industrial application, namely the possibility of using the catalyst in continuous flow reactors. Such considerations will provide useful information for a faster and more effective analysis and optimization of the CWPO process.

Road Traffic Noise Wall Design
Despite the long-term experience in the application of noise walls, the uncertainty in wall panel service life efficiency is almost equal between panels built from established and new materials, which are—because of the desire to increase the sustainability of noise walls—developing at an ever-faster pace. The presented meta-analysis of data collected during a systematic review of concrete, metal, and wood panels’ acoustic and non-acoustic characteristics, long term performance, and cradle-to-gate sustainability aims to reduce this uncertainty and support the process of noise wall design and management by shifting the emphasis in decision making from construction costs to the long-term sustainability of the road traffic noise mitigation project. The multi-criterial analysis showed that when choosing a panel, preference should be given to those using lightweight concrete materials.

Firearm (Tool)
A firearm is primarily a weapon, but can be used as a tool to project either single or multiple objects at high velocity through a controlled explosion. The firing is achieved by the gases produced through rapid, confined burning of a propellant. This process of rapid burning is technically known as deflagration. In older firearms, this propellant was typically black powder, but modern firearms use smokeless powder, cordite, or other propellants. Many firearms such as mortars do not have rifled bores to impart spin to the projectile for improved flight stability, such as is seen with firearms used as weapons, although some are rifled. The lack of rifling can prevent tangling of grappling hook lines, buoy lines, and such, although some firearms intended for use at the longest ranges in these applications are rifled.

Semantic Support of Cultural Heritage
The usage of semantics is not new in cultural heritage disciplines. They are commonly used to define standards for meta-, para-, and provenance information for documenting and archiving. Examples of such standards are LIDO and MIDAS Heritage. These XML schema standards are still used in cultural heritage. In recent years, however, the emergence of the Semantic Web has provided the much-required boost to semantic frameworks and technologies. It also dictates how semantics are defined and used today. Techniques and tools that formalize semantics through formalized knowledge representations have become the norm in different fields applying semantics.

Ground Based Strategic Deterrent
The Ground Based Strategic Deterrent (GBSD) is a future American land-based intercontinental ballistic missile system (ICBM) currently in the early stages of development. It is slated to replace the aging Minuteman III missiles, currently stationed in North Dakota, Wyoming, Montana, Nebraska and Colorado, from 2029 through 2075. In 2020, under the Trump administration, the Department of the Air Force gave the defense contractor, Northrop Grumman, a $13.3 billion sole-source contract for development of the GBSD after Boeing withdrew its proposal. Northrop Grumman's subcontractors on the GBSD include Lockheed Martin, General Dynamics, Bechtel, Honeywell, Aerojet Rocketdyne, Parsons, Textron and others.

Integrated Treatment of Agro-industrial Waste
This document reports a synthetic description of a research work in which a new integrated treatment was defined for the production of biofuel and the recovery of phosphorus compounds from agro-industrial residues. As the first step of the proposed process, anaerobic co-digestion was carried out to produce biogas by exploiting raw waste mixtures. Afterwards, the residual digestates were converted to syngas using supercritical wet gasification (SCWG. Finally, the liquid phases from SCWG were treated to recover the phosphorus content as MgKPO4×6H2O crystals. This integrated treatment could be a suitable approach to exploit agro-wastes because it can produce biofuel and valuable chemicals and generates a residual effluent with a very low polluting load

Functionalised Graphene for Sensing Applications
The demand for gas detection is increasing nowadays. However, its fast detection at room temperature (RT) is a major challenge. Graphene is found to be the most promising sensing material for RT detection, owing to its high surface area and electrical conductivity. The high edge functionalized chemically synthesized graphene derivatives thin films are promising candidates to achieve a fast gas sensing response at room temperature. The high amount of edge functional groups is prominent for the sorption of analyte gas/vapor molecules.

Co-CeO2 Catalyzed Water-Gas Shift Reaction
Co-CeO2 catalysts were synthesized by the different methods to derive the optimal synthetic method and to investigate the effect of the preparation method on the physicochemical characteristics of Co-CeO2 catalysts in the high-temperature water-gas shift (HTS) reaction. Co-CeO2 catalyst synthesized by a sol-gel method features the strong metal to support interaction and the largest amount of oxygen vacancies compared to other catalysts, which affects the catalytic activity. As a result, Co-CeO2 catalyst synthesized by the sol-gel method exhibited the highest WGS activity among the prepared catalysts, even in the severe conditions (high CO concentration: ~38% in dry basis and high gas hourly space velocity: 143,000 h−1).

Microfluidics to Study Membrane Filtration
Membrane filtration processes are best known for their application in the water, oil, and gas sectors, but also in food production they play an eminent role. Filtration processes are known to suffer from a decrease in efficiency in time due to e.g., particle deposition, also known as fouling and pore blocking. Although these processes are not very well understood at a small scale, smart engineering approaches have been used to keep membrane processes running. Microfluidic devices have been increasingly applied to study membrane filtration processes and accommodate observation and understanding of the filtration process at different scales, from nanometer to millimeter and more. In combination with microscopes and high-speed imaging, microfluidic devices allow real time observation of filtration processes.

Epson HX-20
The Epson HX-20 (also known as the HC-20) was the first "true" laptop computer. It was invented in July 1980 by Yukio Yokozawa, who worked for Suwa Seikosha, a branch of Japanese company Seiko (now Seiko Epson), receiving a patent for the invention. It was announced in 1981 as the HC-20 in Japan, and was introduced by Epson in North America as the HX-20 at the 1981 COMDEX computer show in Las Vegas, where it drew significant attention for its portability. It had a mass-market release in July 1982, as the HC-20 in Japan and as the Epson HX-20 in North America. The size of an A4 notebook and weighing 1.6 kg, it was hailed by BusinessWeek magazine as the "fourth revolution in personal computing".
