Design of Sustainable Flexible Pavement
The conventional methodologies for the design of flexible pavements are not adequate in providing solutions that meet the diverse sustainability challenges. Therefore, developing new methodologies and frameworks for the design of flexible pavement has become a priority for most highway agencies. On the other hand, there is no sound sustainable flexible pavement framework at the design phase that considers the key engineering performance, environmental impact, and economic benefits of sustainability metrics. Hence, premature failure of flexible pavements has become a common problem leading to a growing demand for sustainable pavement. Pavement engineers need to have access to tools that permit them to design flexible pavements capable of providing sustainable solutions under various complex scenarios and uncertainties.

AxBy Intermetallics for hydrogen storage
AxBy intermetallics show outstanding performances, notably for stationary hydrogen storage applications. Elemental substitution, whether on the A or B site of these alloys, allows the effective tailoring of key properties such as gravimetric density, equilibrium pressure, hysteresis and cyclic stability for instance.

Comprehensive Review on Wearable Sweat-Glucose Sensors for CGM
The incidence of diabetes is increasing at an alarming rate, and regular glucose monitoring is critical in order to manage diabetes. Currently, glucose in the body is measured by an invasive method of blood sugar testing. Blood glucose (BG) monitoring devices measure the amount of sugar in a small sample of blood, usually drawn from pricking the fingertip, and placed on a disposable test strip. Therefore, there is a need for non-invasive continuous glucose monitoring, which is possible using a sweat sensor-based approach.

Control Strategy for High Speed On/off Valves
Digital hydraulic technology is considered to be a potential solution to replace traditional hydraulic servo control technology in the “Industry 4.0” era. Digital valves mainly consist of incremental digital valves and high speed on/off valves (HSV), of which the former have been abandoned by academia and industry due to its low-frequency and tendency to become out-of-step.

Ford Maverick (1970)
The Ford Maverick is a compact car manufactured and marketed by Ford for model years 1970–1977 in the United States, originally as a two-door sedan employing a rear-wheel drive platform original to the 1960 Falcon — and subsequently as a four-door sedan on the same platform. The Maverick was also manufactured in Venezuela, Canada, Mexico, and from 1970 to 1979, in Brazil. The name "maverick" was derived from the word for unbranded range animals, and the car's nameplate was stylized to resemble the head of Longhorn cattle.

Characteristics and Hazards of Lead–Zinc Tailings
Lead–zinc tailings are the typical solid wastes in mines with high yield and low utilization rates in some countries. They are mainly stockpiled in tailings reservoirs, occupying massive land resources and threatening the health of the environment.

15 Minute City
The 15-minute city is a residential urban concept in which all city residents are able to meet most of their needs within a short walk or bicycle ride from their homes. The concept was popularized by Mayor Anne Hidalgo of Paris, who was in turn inspired by French-Colombian scientist Carlos Moreno. It has been described as a "return to a local way of life. 15-minute cities are built from a series of 15-minute neighborhoods, also known as complete communities or walkable neighborhoods.

Biomass Feedstock
The importance of energy demands that have increased exponentially over the past century has led to the sourcing of other ideal power solutions as the potential replacement alternative to the conventional fossil fuel. However, the utilisation of fossil fuel has created severe environmental issues. The identification of other renewable sources is beneficial to replace the energy utilisation globally. Biomass is a highly favourable sustainable alternative to renewable resources that can produce cleaner, cheaper, and readily available energy sources in the future. The palm oil industry is essentially ideal for the availability of abundant biomass resources, where the multifaceted residues are vital for energy production through the conversion of biomass waste into value-added products simultaneously. This article discusses the utilisation of palm oil and its residues in the energy and transportation sector. Assessment and evaluation on the feasibility of palm oil and its residues were made on the current valorisation methods such as thermochemical and biochemical techniques. Their potential as transportation fuels were concurrently reviewed. This is followed by a discussion on future challenges of palm oil industries that will take place globally, including the prospects from government and non-government organisations for the development of palm oil as a sustainable alternative replacement to fossil fuel. Hence, this review aims to provide further insight into the possibilities of palm oil and its residues towards sustainable development with reduced environmental-related issues.

Proposed Melbourne Rail Extensions
Several proposals have been put forward by various groups to expand the Melbourne rail network—proposals for additional rail lines, extensions to existing lines, as well as electrification to existing lines and new stations on existing lines. Some of these plans were so seriously considered at various times that they appeared in the Melway street directory, and on suburban train destination rolls.
