TL;DR: In this paper, the design, simulation and fabrication of a left-handed metamaterial (LHM) structure was presented, where the combination of the modifled square rectangular Split Ring Resonator (SRR) and the Capacitance Loaded Strip (CLS) were used to obtain the negative value of permeability, " and the negative permittivity, ". Nicolson- Ross-Wier approach was used to identify the double negative region.
Abstract: The design, simulation and fabrication of a left-handed metamaterial (LHM) structure is presented. The combination of the modifled square rectangular Split Ring Resonator (SRR) and the Capacitance Loaded Strip (CLS) were used to obtain the negative value of permeability, " and the negative permittivity, ". Nicolson- Ross-Wier approach was used to identify the double negative region. A good agreement between simulated and measured results has been achieved. Upon incorporation with a single patch microstrip antenna, the performance of the antenna was improved where the gain of the microstrip antenna was increased up to 4dB, and its bandwidth widens from 2.9% to 4.98%. These improvements are due to the negative refraction characteristics of the LHM structure that acts as a lens when placed in front of the antenna.

TL;DR: In this article, a photo-induced CO2-CH4 reaction was investigated under simulated solar energy and the results indicated that photo-activity and selectivity of Cu/g-C3N4 photo-catalyst for CO2 reduction greatly depended on the type of CO2reduction system.

TL;DR: The implementation of an intelligent traffic lights control system using fuzzy logic technology which has the capability of mimicking human intelligence for controlling traffic lights is discussed.
Abstract: Describes the design and implementation of an intelligent traffic lights controller based on fuzzy logic technology. A software has been developed to simulate the situation of an isolated traffic junction based on this technology. It is highly graphical in nature, uses the Windows system and allows simulation of different traffic conditions at the logic controller and a conventional fixed-time controller. Simulation results show that the fuzzy logic controller has better performance and is more cost effective.

TL;DR: In this article, the authors measured the streaming potential coupling coefficient in intact sandstone samples saturated with NaCl brines at concentrations up to 5.5 molL−1 and found that at low salinity, the coupling coefficient decreases in magnitude, but is still measureable up to the saturated concentration limit.
Abstract: [1] We present measurements of the streaming potential coupling coefficient in intact sandstone samples saturated with NaCl brines at concentrations up to 5.5 molL−1. The values we record at low salinity are consistent with those reported previously. As brine salinity increases, the coupling coefficient decreases in magnitude, but is still measureable up to the saturated concentration limit. The magnitude of the zeta potential also decreases with increasing salinity, but approaches a constant value at high salinity. This behaviour is not captured by current models of the electrical double layer. Our results suggest that streaming potential measurements may be used to monitor flow in saline subsurface environments such as deep saline aquifers and hydrocarbon reservoirs. However, they were obtained at laboratory temperature. Future work will focus on the effect of elevated temperatures at high salinity.

TL;DR: In this article, a review aimed at providing a cutting-edge critical assessment of research outputs on SO2 and NOx adsorption from flue gas by surface modified activated carbon is presented.
Abstract: A severe problem associated with combustion of fossil fuels and biomass in the quest for heat and power generation is the release of acidic gases. This posed great health and environmental concerns, and their presence in sufficient amount in flue gas affects the performance of CO2 capture system through formation of heat resistant salts on reaction with the capture medium. Among the various alternatives, removal of the SO2 and NOx gases by adsorption on surface modified activated carbon from renewable sources has proven to be an efficient and robust technology which is attributed to the presence of immobilized chemical species on the carbon surface providing the necessary affinity with the target gaseous pollutants. Thus, the present review aimed at providing a cutting-edge critical assessment of research outputs on SO2 and NOx adsorption from flue gas by surface modified activated carbon. Conspicuously, modification mechanisms, surface characterization, surface chemistry and application of surface modification of activated carbon were discussed elaborately.
