TVS' fantastic-looking flagship - the Apache RR 310 has got an important update for 2019 that should keep a lot of customers happy! Here, in this comprehensive review, we tell you how the new version is to ride and what all has changed, for the good or bad!

Steel is one of the most widely produced industrial products in the world, and the sector depends heavily on a range of raw materials for its production. The aim of this workshop was to better understand the impacts of trade-restrictive raw material policies on the global steel industry and to explore policy approaches that would improve the longer-term efficiency and functioning of these markets.

The world’s consumption of raw materials is set to nearly double by 2060 as the global economy expands and living standards rise, placing twice the pressure on the environment that we are seeing today, according to a new OECD report.

Worldwide, 62 billion tons of natural resources – minerals, wood, metals, fossil and biomass fuels, and construction material – are extracted. On average, that’s almost 10 tons for every person on the earth. Of that, about one fifth ends up as waste and must be reused, recycled or disposed of in a way that is safe for people and the environment.

Extended Producer Responsibility (EPR) is increasingly recognised worldwide as an efficient waste management policy to help improve recycling and reduce landfilling of products and materials. This Forum took place on 17-19 June 2014, in Tokyo, Japan, to identify key challenges and opportunities for further developing EPR policies.

Urgent research is needed to assess the possible risks to human health and ecosystems from the ever-increasing amounts of engineered nanomaterials going into household waste and ending up in the environment, according to a new OECD report.

Advanced economies have reduced their consumption of raw materials and improved waste management, but more should be done to design and produce goods in a way that uses fewer natural resources and produces less waste, according to a new OECD report.

This communication outlines the achievements made so far by OECD in addressing the human health and environmental safety implications of manufactured nanomaterials

This is a guidance on sample preparation and dosimetry, to which special attention should be paid when testing nanomaterials for human health and environmental safety endpoints.

This document provides information on current/planned activities related to the safety of manufactured nanomaterials in OECD member and non-member countries that attended at the 10th meeting of OECD’s Working Party on Manufactured Nanomaterials (Paris France, 27-29 June 2012).

This document follows on from a report entitled Important Issues on Risk Assessment of Manufactured Nanomaterials [ENV/JM/MONO(2012)8]. This report identified a range of issues which the WPMN considered important in risk assessment and which should be addressed in the future. It summarised results of a survey which was circulated to delegations of the WPMN, methodologies used to analyze the survey, and the identified priorities.

The OECD has recommended its Member Countries apply existing international and national chemical regulatory frameworks to manage the risks associated with manufactured nanomaterials.

This document includes the conclusions and recommendations resulting from a workshop that addressed the ecotoxicology and environmental fate of manufactured nanomaterials, and in particular the applicability of existing OECD Test Guidelines (TG) related to these topics. A number of TG developments are underway at OECD as a follow-up to these recommendations.

This report includes the conclusions and recommendation of an expert workshop on Physical-Chemical Properties of Manufactured Nanomaterials and Test Guidelines organized by OECD’s Working Party on Manufactured Nanomaterials. The workshop addressed issues relevant to the physical-chemical properties of manufactured nanomaterials from a regulatory perspective point with a view to the need for new or adapted test guidelines.

Today the OECD marks the end of a seven year experimental testing programme, investigating 11 commercially viable nanomaterials across 110 chemical tests. The results were co-ordinated across 11 countries with tests and data generated from government agencies, universities, research institutions and businesses. Over 780 studies on the specific properties of nanomaterials were undertaken.

This document provides background information on activities related to manufactured nanomaterials, as well as other activities on nanotechnologies at the international level. The information provided in this document captures OECD activities between February and December 2013.

This new document focuses on the evaluation of test methods applied to determine the physico-chemical properties of different types of nanomaterials.

Nanomaterials have unique physical and chemical features. OECD's Decision Framework and Guiding Principles tools fill data gaps in the hazard characterisation by identifying the most useful parameters and best available methods for a given type of nanomaterial.

VACB squads to conduct checks across State

Two in situ `nanoreactors' for high-resolution imaging of catalysts have been designed and applied at the hard X-ray nanoprobe endstation at beamline P06 of the PETRA III synchrotron radiation source. The reactors house samples supported on commercial MEMS chips, and were applied for complementary hard X-ray ptychography (23 nm spatial resolution) and transmission electron microscopy, with additional X-ray fluorescence measurements. The reactors allow pressures of 100 kPa and temperatures of up to 1573 K, offering a wide range of conditions relevant for catalysis. Ptychographic tomography was demonstrated at limited tilting angles of at least ±35° within the reactors and ±65° on the naked sample holders. Two case studies were selected to demonstrate the functionality of the reactors: (i) annealing of hierarchical nanoporous gold up to 923 K under inert He environment and (ii) acquisition of a ptychographic projection series at ±35° of a hierarchically structured macroporous zeolite sample under ambient conditions. The reactors are shown to be a flexible and modular platform for in situ studies in catalysis and materials science which may be adapted for a range of sample and experiment types, opening new characterization pathways in correlative multimodal in situ analysis of functional materials at work. The cells will presently be made available for all interested users of beamline P06 at PETRA III.

This feature article reviews the control and understanding of nanoparticle shape from their crystallography and growth. Particular emphasis is placed on systems relevant for plasmonics and catalysis.

The title compound, hexa­kis­(2-methyl-1H-imidazol-3-ium) hepta­molybdate 2-methyl-1H-imidazole disolvate dihydrate, (C4H7N2)6[Mo7O24]·2C4H6N2·2H2O, was prepared from 2-methyl­imidazole and ammonium hepta­molybdate tetra­hydrate in acid solution. The [Mo7O24]6− hepta­molybdate cluster anion is accompanied by six protonated (C4H7N2)+ 2-methyl­imidazolium cations, two neutral C4H6N2 2-methyl­imidazole mol­ecules and two water mol­ecules of crystallization. The cluster consists of seven distorted MoO6 octa­hedra sharing edges or vertices. In the crystal, the components are linked by N—H⋯N, N—H⋯O, O—H⋯O, N—H⋯(O,O) and O—H⋯(O,O) hydrogen bonds, generating a three-dimensional network. Weak C—H⋯O inter­actions consolidate the packing.

CsCl-type materials have many outstanding characteristics, i.e. simple in structure, ease of synthesis and good stability at room temperature, thus are an excellent choice for designing functional materials. Using high-throughput first-principles calculations, a large number of topological semimetals/metals (TMs) were designed from CsCl-type materials found in crystallographic databases and their crystal and electronic structures have been studied. The CsCl-type TMs in this work show rich topological character, ranging from triple nodal points, type-I nodal lines and critical-type nodal lines, to hybrid nodal lines. The TMs identified show clean topological band structures near the Fermi level, which are suitable for experimental investigations and future applications. This work provides a rich data set of TMs with a CsCl-type structure.

In the past three years, Dirac half-metals (DHMs) have attracted considerable attention and become a high-profile topic in spintronics becuase of their excellent physical properties such as 100% spin polarization and massless Dirac fermions. Two-dimensional DHMs proposed recently have not yet been experimentally synthesized and thus remain theoretical. As a result, their characteristics cannot be experimentally confirmed. In addition, many theoretically predicted Dirac materials have only a single cone, resulting in a nonlinear electromagnetic response with insufficient intensity and inadequate transport carrier efficiency near the Fermi level. Therefore, after several attempts, we have focused on a novel class of DHMs with multiple Dirac crossings to address the above limitations. In particular, we direct our attention to three-dimensional bulk materials. In this study, the discovery via first principles of an experimentally synthesized DHM LaNiO3 with many Dirac cones and complete spin polarization near the Fermi level is reported. It is also shown that the crystal structures of these materials are strongly correlated with their physical properties. The results indicate that many rhombohedral materials with the general formula LnNiO3 (Ln = La, Ce, Nd, Pm, Gd, Tb, Dy, Ho, Er, Lu) in the space group R3c are potential DHMs with multiple Dirac cones.

X-ray imaging of soft materials is often difficult because of the low contrast of the components. This particularly applies to frozen hydrated biological cells where the feature of interest can have a similar density to the surroundings. As a consequence, a high dose is often required to achieve the desired resolution. However, the maximum dose that a specimen can tolerate is limited by radiation damage. Results from 3D coherent diffraction imaging (CDI) of frozen hydrated specimens have given resolutions of ∼80 nm compared with the expected resolution of 10 nm predicted from theoretical considerations for identifying a protein embedded in water. Possible explanations for this include the inapplicability of the dose-fractionation theorem, the difficulty of phase determination, an overall object-size dependence on the required fluence and dose, a low contrast within the biological cell, insufficient exposure, and a variety of practical difficulties such as scattering from surrounding material. A recent article [Villaneuva-Perez et al. (2018), Optica, 5, 450–457] concluded that imaging by Compton scattering gave a large dose advantage compared with CDI because of the object-size dependence for CDI. An object-size dependence would severely limit the applicability of CDI and perhaps related coherence-based methods for structural studies. This article specifically includes the overall object size in the analysis of the fluence and dose requirements for coherent imaging in order to investigate whether there is a dependence on object size. The applicability of the dose-fractionation theorem is also discussed. The analysis is extended to absorption-based imaging and imaging by incoherent scattering (Compton) and fluorescence. This article includes analysis of the dose required for imaging specific low-contrast cellular organelles as well as for protein against water. This article concludes that for both absorption-based and coherent diffraction imaging, the dose-fractionation theorem applies and the required dose is independent of the overall size of the object. For incoherent-imaging methods such as Compton scattering, the required dose depends on the X-ray path length through the specimen. For all three types of imaging, the dependence of fluence and dose on a resolution d goes as 1/d4 when imaging uniform-density voxels. The independence of CDI on object size means that there is no advantage for Compton scattering over coherent-based imaging methods. The most optimistic estimate of achievable resolution is 3 nm for imaging protein molecules in water/ice using lensless imaging methods in the water window. However, the attainable resolution depends on a variety of assumptions including the model for radiation damage as a function of resolution, the efficiency of any phase-retrieval process, the actual contrast of the feature of interest within the cell and the definition of resolution itself. There is insufficient observational information available regarding the most appropriate model for radiation damage in frozen hydrated biological material. It is advocated that, in order to compare theory with experiment, standard methods of reporting results covering parameters such as the feature examined (e.g. which cellular organelle), resolution, contrast, depth of the material (for 2D), estimate of noise and dose should be adopted.

A scanning soft X-ray spectromicroscope was recently developed based mainly on the photon-in/photon-out measurement scheme for the investigation of local electronic structures on the surfaces and interfaces of advanced materials under conditions ranging from low vacuum to helium atmosphere. The apparatus was installed at the soft X-ray beamline (BL17SU) at SPring-8. The characteristic features of the apparatus are described in detail. The feasibility of this spectromicroscope was demonstrated using soft X-ray undulator radiation. Here, based on these results, element-specific two-dimensional mapping and micro-XAFS (X-ray absorption fine structure) measurements are reported, as well as the observation of magnetic domain structures from using a reference sample of permalloy micro-dot patterns fabricated on a silicon substrate, with modest spatial resolution (e.g. ∼500 nm). Then, the X-ray radiation dose for Nafion® near the fluorine K-edge is discussed as a typical example of material that is not radiation hardened against a focused X-ray beam, for near future experiments.

The microstructures of six stacking-faulted industrially produced cobalt- and aluminium-bearing nickel layered double hydroxide (LDH) samples that are used as precursors for Li(Ni1−x−yCoxAly)O2 battery materials were investigated. Shifts from the brucite-type (AγB)□(AγB)□ stacking pattern to the CdCl2-type (AγB)□(CβA)□(BαC)□ and the CrOOH-type (BγA)□(AβC)□(CαB)□ stacking order, as well as random intercalation of water molecules and carbonate ions, were found to be the main features of the microstructures. A recursive routine for generating and averaging supercells of stacking-faulted layered substances implemented in the TOPAS software was used to calculate diffraction patterns of the LDH phases as a function of the degree of faulting and to refine them against the measured diffraction data. The microstructures of the precursor materials were described by a model containing three parameters: transition probabilities for generating CdCl2-type and CrOOH-type faults and a transition probability for the random intercalation of water/carbonate layers. Automated series of simulations and refinements were performed, in which the transition probabilities were modified incrementally and thus the microstructures optimized by a grid search. All samples were found to exhibit the same fraction of CdCl2-type and CrOOH-type stacking faults, which indicates that they have identical Ni, Co and Al contents. Different degrees of interstratification faulting were determined, which could be correlated to different heights of intercalation-water-related mass-loss steps in the thermal analyses.
