The crystal structure of the organic pigment 2-monomethyl-quinacridone (Pigment Red 192, C21H14N2O2) was solved from X-ray powder diffraction data. The resulting average structure is described in space group Poverline 1, Z = 1 with the molecule on the inversion centre. The molecules are arranged in chains. The molecules, which have no inversion symmetry, show orientational head-to-tail disorder. In the average structure, the methyl group is disordered and found on both ends of the molecule with an occupancy of 0.5 each. The disorder and the local structure were investigated using various ordered structural models. All models were analysed by three approaches: Rietveld refinement, structure refinement to the pair distribution function (PDF) and lattice-energy minimization. All refinements converged well. The Rietveld refinement provided the average structure and gave no indication of a long-range ordering. The refinement to the PDF turned out to be very sensitive to small structural details, giving insight into the local structure. The lattice-energy minimizations revealed a significantly preferred local ordering of neighbouring molecules along the [0ar 11] direction. In conclusion, all methods indicate a statistical orientational disorder with a preferred parallel orientation of molecules in one direction. Additionally, electron diffraction revealed twinning and faint diffuse scattering.

The crystal structure of the nanocrystalline pigment mono­methyl-quinacridone was solved from X-ray powder data. The orientational disorder was investigated using Rietveld refinements, structure refinement to the pair-distribution function, and lattice-energy minimizations of various ordered structural models.

Relativistic electron diffraction depends on linear and quadratic terms in the electric potential, the latter being neglected in the frequently used relativistically corrected Schrödinger equation. The quadratic electric potential term modifies atomic scattering amplitudes in particular for large-angle scattering and backscattering. The respective correction increases with increasing scattering angle, increasing atomic number and increasing kinetic energy. Conventional tabulations for electron scattering and its large-angle extrapolations can be amended in closed form by a universal correction based on the screened Coulomb potential squared.

The methods for X-ray crystal orientation are rapidly evolving towards versatility, fewer goniometry measurements, automation, high accuracy and precision. One method that attracts a lot of attention is energy-dispersive X-ray diffraction (EDXRD) which is based on detecting reflections from crystallographic planes in a crystal at fixed angles of a parallel polychromatic X-ray incident beam. In theory, an EDXRD peak can move in a diffraction pattern as a function of a crystallographic plane d-spacing and its orientation relative to a fixed direction in space can change also. This is equivalent to the possibility of measuring the orientation of single crystals. The article provides a modeling for the EDXRD method whose main feature is the nonmoving crystal in the sense of traditional goniometry where the angle measurements of diffracting planes are a must. The article defines the equation of orientation for the method and shows the derivation in great detail. It is shown that the exact solutions of the equations can be obtained using the generalized reduced gradient method, a mathematical subroutine that is implemented in Excel software. The significance and scientific impact of the work are discussed along with the validated tested results.

Features of azimuthal plots for RHEED and its new counterpart, RHEPD, are discussed. The plots, for both electrons and positrons, are determined using dynamical diffraction theory.

A new report from the National Research Council examines and, when possible, estimates hidden costs of energy production and use.

The U.S. Department of Energy should place a higher priority on developing an accurate and actionable inventory of agency-owned or managed properties that can be leased or sold for energy development, says a new report from the National Academies of Sciences, Engineering, and Medicine.

With the sharp and largely unexpected increase in the long-distance movement of domestically produced crude oil, ethanol, and natural gas since 2005, a number of concerns have arisen about the safe transport of these hazardous materials, particularly in relation to railroad track defects, rural communities’ emergency response preparedness, and the older tank car designs that will continue to be used in multi-car unit trains, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Over the next several decades as the global population grows, society will be faced with pressing challenges such as providing reliable supplies of food and water, diminishing climate change and adapting to its impacts, and building healthy, resilient cities.

Along with participation in the International Thermonuclear Experimental Reactor (ITER) project – a large, international burning plasma experiment – the U.S. Department of Energy (DOE) should start a national program of accompanying research and technology to build a compact pilot plant that produces electricity from fusion at the lowest possible capital cost, says a new report from the National Academies of Sciences, Engineering, and Medicine.

This project, along with two other new projects, increases the company's order backlog by 65%.

Shares of WPX Energy traded 25% higher after President Trump tweeted that he expected a deal between Russia and Saudi Arabia to scale back oil production.

The new agreement and its potential impact on Point Loma Resources are discussed in a Mackie Research Capital Corp. report.

A new study highlights the positive effects of plants and trees in cities. Urban green areas provide shade and reduce temperature fluctuations, bringing average temperatures down, while covering roofs with plants, rather than black roofs, reduces the energy required to heat and cool buildings.

Green roofs can cool buildings in summer and prevent heat loss in winter. A new study suggests, however, that in the warm climates of southern Europe the additional cost of watering means that 'cool roof coatings??? may be more cost effective.

Efforts to address climate change and protect natural ecosystems can – and need to – benefit each other. But conflicts can arise. This Future Brief focuses on how land-based ecosystems are affected by wind and solar photovoltaic (PV) development, and how win-win solutions which maximise both conservation and climate benefits may be developed. Recommendations include careful site planning, regeneration and enhancement, and use of multi-level ecosystem data.

Relatively simple, low-cost measures, such as insulating walls and installing solar collectors and efficient heaters for hot water can significantly reduce energy consumption in housing developments, according to a recent study from Portugal. Energy-efficient homes not only benefit the environment, but were found to potentially reduce residents’ energy bills by over half in an apartment block studied by the researchers.

A method has been developed to compare how EU Member States have implemented the Energy Performance Buildings Directive. It suggests that implementation varies widely across Europe but that the Czech Republic, Finland, Portugal and Slovakia have kept to the Directive’s aims and guidelines most closely, based on data available in 2009.

In a recent experiment in Norway, electrical appliance stores increased their sales of energy-efficient tumble driers when consumers were made aware of their cheaper lifetime operating costs by shop staff and a new product labelling system.

Whilst there is interest in bioenergy as a renewable alternative to fossil fuels, there is also concern about its environmental impact. A recent study demonstrates that potential bioenergy crops in Hawaii are 2 to 4 times more likely to be invasive than other plants.

A Dutch study has assessed the water requirements of 13 bioenergy crops across the world. The findings could help select the best crops and locations to produce bioenergy.

Large-scale cultivation of bioenergy crops on marginal land is unfeasible, according to a recent study. While limiting bioenergy crops to less productive land could cut the sector’s impact on food prices, the financial incentive to grow crops on more productive land may be too strong for landowners to ignore, the researchers suggest.

Energy efficiency is at the centre of EU policy for achieving a fundamental transformation of Europe’s energy systems by 2030. This Thematic Issue reveals the complexity of the issue of energy efficiency, its links with resource efficiency and the wide range of factors influencing it, from technology to social practices.

Researchers have developed a straightforward approach to help small to medium enterprises (SMEs) analyse their energy use and increase efficiency. They tested the methodology on 280 businesses in Europe, which, as a result, invested more than €10m in energy-saving measures. The measures reduced energy use by 6 500 toe (tonnes of oil equivalent) per year and avoided 13 500 tonnes of CO2 emissions.

A recent study has analysed risks to European renewable industries from the Chinese supply of critical raw materials. The offshore wind sector was found to be the most vulnerable of the renewable industries to supply risks. EU and industry strategies should be able to deal with these supply risks in the short term, but there are potential long-term risks to solar and wind sectors. The development of alternative technologies less reliant on these raw materials, and methods to recycle these materials is, therefore, a priority.

Researchers have developed a new energy map that traces the flow of global energy from the fuel sources to the final services provided. The study provides new insight into the potential of energy efficiency measures by focusing on technologies rather than economic sectors.

A set of indicators has been devised to assess the vulnerability of energy systems to climate change and suggest possible adaptation measures that could be taken in response.

Information policy measures aimed at reducing household energy consumption need to take a number of approaches, according to Swedish researchers. They should stress both economic and environmental motives and encourage public discussion.

New EU-funded research from Finland has indicated that poor communication between producers of energy-efficient housing technologies and potential house-buyers is a major barrier to sustainable housing. It suggests that government bodies can encourage energy-efficiency innovations not only through regulations but also by improving information flow.

Environmental impact studies which are conducted early on in the development of wave and tidal-power schemes allow the schemes' technology to be adapted to consider their impacts on marine ecosystems, according to a recent study which reports on a Swedish research wave park.

A recent study in Finland suggests new building regulations will lead to a substantial reduction in the total energy demand and CO2 emissions in new apartment buildings. This could have an impact on the source of energy used for new buildings. In particular, the demand for space heating will fall, which could have an impact on the source of energy used for new buildings.

Recent research from China suggests that partially converting both natural gas and coal into 'syngas' fuel for power generation can generate around 6 per cent more electricity than competing 'conventional' gasification methods. The savings arise from more efficient use of the chemical energy in gas and coal which is lost in a conventional burner.

New research identifies important influences on the energy and environmental performance of biofuels made from agricultural crops. Type of land use change, type of biofuel crop and the by-products from the conversion process all influence performance.

There are no technical or economic barriers to providing all of the world’s energy from renewable sources, according to a recent study. With a concerted effort, including reduced demand and international cooperation, the researchers suggest that the world could be entirely reliant on renewable energy for electric power, transportation and heating/cooling by 2050.

Renewable technologies could supply 77 per cent of the world demand for energy by 2050, according to a report recently published by the IPCC. However, strong and flexible national and international policies are needed to stimulate investment and encourage accelerated use of renewable energy. The most pessimistic scenarios see the renewables share remaining almost static until mid-century.

New research has investigated the complex relationship between energy consumption and public health, by analysing historical data from around the world. It indicates that electricity does not provide additional health benefits for countries with low levels of infant mortality, and that increased coal consumption has negative health impacts.

Connecting Europe and North Africa with a single, long-distance electricity ‘supergrid’ is technically possible and the cheapest option available to meet Europe’s renewable energy targets, according to new research. However, significant political challenges, such as minimising the perception of risk and attracting sufficient investment, need to be overcome.

A new survey from 2010 reveals that upfront costs of up to €14,000 and lengthy payback times can discourage even the most environmentally conscious citizens from installing domestic renewable technology, such as solar panels and wind generators. However, people signing up to a ‘climate pledging’ scheme were still at least 11 times more likely to install these technologies than the average person in the UK.

Techniques for reducing the noise caused by wind turbines are reviewed in a new study. Noise pollution is one drawback of wind power and restricts where wind farms can be located in relation to people and wildlife. The researchers identify methods that could aid the design of low-noise wind turbines, including modifying the blade’s shape and adding rows of brushes to the edge of the blade.

New insights into energy saving behaviour in the home could help inform measures to ensure the EU meets energy efficiency targets. A new study shows that younger and more educated households have more positive attitudes towards energy conservation, and suggests that greater emphasis of the financial benefits associated with energy savings could help reduce energy use in households that are less-motivated to save energy for environmental reasons.

Some scientists have suggested that, when all potential inefficiencies are accounted for, local food distribution systems may be less sustainable than globalised systems. However, new research examining the behaviour of participants in local food networks in France suggests that they can be as energy efficient as globalised systems.

In a recent experiment in Norway, electrical appliance stores increased their sales of energy-efficient tumble driers when consumers were made aware of their cheaper lifetime operating costs by shop staff and a new product labelling system.
