The cationic complex in the title compound, [Ir(C9H7N2)2(C12H8N2)]PF6, comprises two phenylpyrazole (ppz) cyclometallating ligands and one 1,10-phenanthroline (phen) ancillary ligand. The asymmetric unit consists of one [Ir(ppz)2(phen)]+ cation and one [PF6]− counter-ion. The central IrIII ion is six-coordinated by two N atoms and two C atoms from the two ppz ligands as well as by two N atoms from the phen ligand within a distorted octahedral C2N4 coordination set. In the crystal structure, the [Ir(ppz)2(phen)]+ cations and PF6− counter-ions are connected with each other through weak intermolecular C—H...F hydrogen bonds. Additional C—H...π interactions between the rings of neighbouring cations consolidate the three-dimensional network. Electron density associated with additional disordered solvent molecules inside cavities of the structure was removed with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s). The title compound has a different space-group symmetry (C2/c) from its solvatomorph (P21/c) comprising 1.5CH2Cl2 solvent molecules per ion pair.

Los Angeles Unified School District officials are making plans for summer — and for now, none of those plans involve reopening school campuses shuttered by the coronavirus pandemic.

In a video address Monday, Superintendent Austin Beutner said LAUSD leaders have "made no decisions" about whether the fall semester — still scheduled to begin on August 18 — will involve students in classrooms, online or both. He said it's not clear what the public health conditions will allow.

Last week, Governor Gavin Newsom surprised many educators when he suggested California schools could resume in-person instruction early — perhaps even as soon as mid-July. Newsom fears the longer students remain at home, the farther they'll fall behind academically. Read more about this on LAist.

Effective ‘knowledge exchange’ - the process of producing, sharing, understanding and using knowledge - is vital to good environmental management. New research has uncovered five principles for this process which could help researchers, decision makers and other parties work together to better manage environmental change.

A Bosnian pine (Pinus heldreichii) growing in the highlands of northern Greece has been dendrocronologically dated to be more than 1075 years old. This makes it currently the oldest known living tree in Europe. The millenium old pine was discovered by scientists from Stockholm University (Sweden), the University of Mainz (Germany) and the University of Arizona (USA).

A research update on climate change has indicated that many global risks are now assessed as stronger than predicted by the 2007 IPCC Fourth Assessment Report (AR4). The risk of large sea-level rise, extreme weather events and ocean acidification are all thought to be underestimated by the AR4.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.)

The only way to establish a long-lasting and effective strategy for forest management is through collaboration between ‘conventional’ scientists and local experts, according to new research.

Understanding the social context of Swedish forestry is key to understanding how the sector could be persuaded to move beyond ‘business-as-usual’ practices, to prepare for future climate risks, argues a new study. Using an approach that provides insights for future behavioural change more widely, the researchers explore the influences on forest managers’ behaviour, and highlight certification schemes as one important driver of actions which make forests better adapted to climate change. Knowledge on climate change risks and actions in itself is not enough to change behaviour, the study finds. For many environmentalists it may seem ‘logical’ for forestry to adapt now to future climate change: it epitomises an industry where actions taken today will determine long-term development, given that trees will not be harvested until 70–90 years after planting. However, the sector has taken limited actions to adapt, despite an abundance of available information on the impacts of climate change — such as storms, drought and changes in insect population.

Outputs of conservation planning research are likely to be translated into action more quickly and successfully if a transdisciplinary approach is adopted, according to a recent study. The researchers have applied a transdisciplinary framework 'pyramid of knowledge' to aid in understanding the process of converting research into action, which may also be applicable to other academic disciplines.

Agricultural land use presents a number of environmental challenges, which the European Commission is committed to addressing through a range of agri-environmental policies. A new study points to the importance of aligning agri-environmental policies with farmers’ needs and operations. Using the case of land clearing in Finland, the research underlines the importance of incorporating input from grassroots stakeholders into policy design.

Research assessments should focus more on engagement processes and less on impacts and outcomes, a new study suggests. The authors examined researchers’ intended impacts and motivational factors, and stated that a change in research evaluation methods, together with better direction from university managers, could help incentivise knowledge exchange and engagement between departments and non-academic entities.

A recent analysis highlights the difference between the academic concept and the practical concept of ecosystem services. It suggests that academic science aims to discover and apply general and timeless concepts to measure ecosystem services, whereas in practice, stakeholders' valuations of ecosystem services vary with place and time.

New research has explored how well different governance systems can achieve desirable conservation outcomes. Results confirmed the importance of adaptive management, which relies on regular monitoring to enable 'learning through doing' to refine actions, and suggested that leadership using expert knowledge was also significant in successful governance.

The willingness of farmers to create wetlands within agri-environment schemes (AES) has been assessed as part of a new study in Sweden. Land-owning farmers and those with prior knowledge of the Water Framework Directive (WFD) were more likely to create wetlands than leasehold farmers or those with no prior knowledge of WFD. Common reasons for not wanting to take part in the scheme included the farmers’ senior age, that wetlands would not be suitable on the farm and high costs — leading the researchers to suggest that changes in subsidy payments may increase wetland creation.

Calculating the costs of nitrous oxide (N2O) emissions to society as well as business is vital to understand the true economic gains of reducing N2O emissions, new research suggests. Increasing nitrogen use efficiency by 20% by 2020 could bring global annual benefits to the climate, health and environment worth US $160 (€118) billion, the researchers conclude.

The most up-to-date knowledge and data must be used to assess policy objectives, new research confirms. Studying air pollution environmental quality targets set by the National Emission Ceilings (NEC) Directive1, a new study has shown that if 2001 data are used to assess progress, most such targets appear to have been met. However, more recent and accurate current data show that this may not be the case.

The most important findings from over a decade of research into environmentally persistent free radicals (EPFRs), a new class of environmental pollutants, are presented in a recent review. These toxic particles could be partly responsible for some of the health problems, such as asthma, associated with particulate matter (PM) exposure. The researchers issue a warning that some engineered nanomaterials (ENMs) could increase levels of EPFRs in the environment.
