Thirteen years ago Andre Geim and Kostya Novoselov— two researchers at the University of Manchester—isolated graphene for the first time. Prior to that day scientists knew the one atom thick, 2D crystal material existed, but no one had worked out how to extract it from graphite. During one of their weekly Friday night experiment sessions the duo removed flakes from a lump of bulk graphite with sticky tape and noticed that some flakes were thinner than others. They kept separating graphite fragments repeatedly until they created flakes that were just one atom thick. Six years later they won the Nobel Prize in Physics for their discovery. Today Manchester continues to serve as a center for graphene innovation. Coined ‘Graphene City,’ the University of Manchester is home to over 250 researchers working on graphene and has over 70 industry partners, including high-profile companies Dyson, Merck, GlaxoSmithKline, Rolls-Royce, Samsung, Sharp, and Siemens. “Our vision of Graphene City is a bit like Silicon Valley,” said James Baker, business director of graphene at the University of Manchester. “We are trying to create a hub in Manchester, where at the heart of activity we have the University of Manchester where we have lots of academics and scientists, and then we also have international partnerships. The biggest chance of graphene being a success is through that partnership and collaboration model and this Graphene City concept.” As part of this initiative, a significant investment has been made in two state-of-the-art facilities. The first, the National Graphene Institute (NGI), houses both academics carrying out fundamental research as well as industrial partners. The goal of the £61-million facility is to foster collaboration between the two and grow early-stage applications of graphene-based products. The £60m Graphene Engineering Innovation Center (GEIC)—which will open in the second half of 2018—will foster commercialization of those early-stage applications, serving as a facility to scale-up and test graphene-based products. Both of these facilities will tackle some of the major challenges regarding graphene. While many different companies are creating graphene, how to best use the material in the most efficient and intelligent manner is still unclear. “The challenge is less now how to produce a material, it is how do you disperse or how do you mix it, how do you go from a 2D material into a 3D product or application, and then how do you get that consistency, and qualification and certainty that it is safe?” said Baker. “We have over 70 industry partners that we are working with to look at those challenges. That will increase and accelerate once the GEIC is completed this year.” Since it wasn’t discovered until 2004, graphene is still in its “teenage years,” said Baker, and has only been seriously investigated for the past six to seven years. A material that new would typically take decades before significant products were commercialized, he said. Graphene City was created to change that. “We are looking to accelerate the production of graphene products and applications,” said Baker. “By working in a much more concurrent way, we can hopefully take a new material which typically takes 20 to 30 years to get to the market, and really reduce the time, and get it to market as quickly as possible.” Right now, there are a few simple products utilizing graphene in the marketplace. Most use the material as a composite or coatings, adding it to other materials instead of creating a brand new product with it. Using this technique, graphene has been used to created ‘smarter’ tennis rackets, cycle tires, light bulbs, and inks. However, the potential of graphene spans far beyond simple composite or coatings. Graphene membranes could be created and used for water desalination, nuclear cleanup, or novel fuel cells. The material also has potential in the aerospace and electrical industries, as well as biomedical applications such as using it to create novel drug delivery systems or artificial skin. In addition, the discovery of graphene has opened up a new world of potential 2D materials, and researchers are now investigating multiple types of materials that are also isolated to a single atomic layer. These 2D materials could be stacked together layer by layer to create a multi-functional, ‘smart’ material, said Baker. “We are now applying a similar science to a whole family of materials, and today we are studying over 100 different 2D materials,” said Baker. “This is huge is terms of its potential. It has the potential to change the world.”

Stability analysis of Surabhi landslide in the Dehradun and Tehri districts of Uttaranchal located in Mussoorie India, has been simulated numerically using the distinct element method focusing on the weak zones (fracture). This is an active landslide on the main road toward the town centre, which was triggered after rainfall in July-August 1998. Understanding the behaviour of this landslide will be helpful for planning and implementing mitigation measures. The first stage of the study includes the total area of the landslide. The area identified as the zone of detachment is considered the most vulnerable part of the landslide. Ingress of water and increased pore pressures result in reduced mobilized effective frictional resistance, causing the top layer of the zone of detachment to start moving. The corresponding total volume of rock mass that is potentially unstable is estimated to 11.58 million m3. The second stage of this study includes a 2D model focussing only on the zone of detachment. The result of the analyses including both static and dynamic loading indicates that most of the total displacement observed in the slide model is due to the zone of detachment. The discontinuum modelling in the present study gives reasonable agreement with actual observations and has improved understanding of the stability of the slide slope. © 2011 Springer-Verlag.

Low frequency sound, in addition to the effects of audible sound, contributes to human annoyance and building damage by inducing building vibration. This involves whole body vibration sensing of humans, and therefore frequencies down to a few Hz become important. Here, the results of a study of low frequency sound and its generation of building vibration and induced indoor sound is presented. The study is conducted by combining both full scale field tests and numerical simulations. It is shown that the low frequency sound interaction with the fundamental frequencies of the building components combined with air leaks in the building envelope are the main factors that govern transmission of sound into the building. Furthermore, radiation from vibrating ceiling and walls seems to be the dominant source of the low frequency indoor sound, and floor vibration is acoustically driven by the indoor sound pressure in the room. Due to the low frequencies in question, tools to predict sound and vibration, and design mitigation measures at low frequencies noise and vibration in building structures are virtually non-existent. To this end, a finite element model combining acoustic wave propagation and structural dynamics presented in this paper provides a first step. Using this model, a number of countermeasures has been tested and some proven effective in this low frequency range. © 2011 Institute of Noise Control Engineering.

In this contribution, we review the current practice in submarine landslides research, in which a multidisciplinary approach is essential. These include, but are not limited to, geophysics, geology, geochemistry, geotechnics and geomechanics, slope stability simulations, landslide dynamics, consequence analysis (e.g., tsunami, impact, risk assessment). Following a brief introduction on the - typical - three-phase landslide development, we address a number of issues at stake (e.g., gas, hydrate, excess pore pressure) that should be addressed in more detail in future research activities within this field. These include in situ measurements, but also the advanced use of geophysical methods to derive soil properties in the shallow sub-surface. Finally, we highlight activities conducted to develop the Finneidfjord area (northern Norway) as a natural field laboratory for submarine landslide investigations. When it comes to smaller-scale landslides, high lateral and vertical resolution is paramount to understand such landslides, which still can have devastating consequences.

Eastern Indonesia and the southern Philippines comprise a huge and seismically highly active region that has received less than the deserved attention in tsunami research compared with the surrounding areas exposed to the major subduction zones. In an effort to redress the balance the tsunami hazard in this region is studied by establishing a tsunami event database which, in combination with seismological and tectonic information from the region, has allowed us to define and justify a number of 'credible worst-case' tsunami scenarios. These scenarios have been used in numerical simulations of tsunami generation and propagation to study maximum water level along potentially affected shorelines. The scenarios have in turn been combined to provide regional tsunami hazard maps. In many cases the simulations indicate that the maximum water level may exceed 10 m locally and even reach above 20 m in the vicinity of the source, which is of the same order as what is forecasted along the Sumatra and Java trenches for comparable return periods. For sections of coastlines close to a source, a tsunami may strike only a few minutes after it is generated, providing little time for warning. Moreover, several of the affected areas are highly populated and are therefore also high risk areas. The combination of high maximum water levels, short warning times, dense populations, and relatively short return periods suggests strongly that the tsunami hazard and risk in these regions are alarmingly high. © 2012.

Pipelines laid on the seabed are subjected to loads that may cause unacceptable displacements. On fine-grained soils, the capacity of a pipeline to resist these loads is affected by the pipe embedment and any excess pore pressures remaining in the surrounding soil from the laying process. This paper presents results from model tests, performed at near to full scale, investigating the embedment response and the subsequent pore pressure equalisation of a pipeline on a high plasticity marine clay. Existing models for the penetration and dissipation processes are compared with the experimental data. Conventional undrained bearing capacity theory, making minor allowances for strain rate and softening effects, shows good agreement with the observed penetration response. Dissipation solutions based on elastic and elasto-plastic soil models capture the general shape of the pore pressure response. The operative coefficient of consolidation varies between tests, spanning the range between the compression and recompression values observed in oedometer tests. The observations validate the theoretical solutions for penetration resistance, and highlight the uncertainty that must be considered in estimating equalisation times. © 2016, ICE Publishing.
