The hydrothermal technique was applied to prepare a new metal–organic framework, MIL-100(Fe), which was modified by ultrasonic impregnation with different wt % of copper. The results showed that the NOx conversion over 2.3Cu-MIL-100(Fe) was 100 % at 275 °C and maintained at ≥ 85 %, with N2 selectivity ≥ 90 % in the temperature range of 275–400 °C and high SO2 resistance. An increase in the Cu content up to 2.3 wt% showed the highest surface area ...

Pyrolysis of polyolefins generates a large amount of olefins, which can serve as a valuable feedstock for the synthesis of chemicals. Nevertheless, their effective utilization requires refining owing to their diverse carbon distribution. This study performed a comprehensive GCxGC analysis of pyrolysis oils derived from waste polypropylene (PP) and waste high-density polyethylene (HDPE). The chemical composition of PP pyrolysis oil exhibited a ...

Against the backdrop of growing environmental and social issues in the agri-food sector, voluntary sustainability standards (VSS) have proliferated as a non-state, market-based tool for sustainability in global food value chains. VSS are especially prominent in tropical commodity sectors where the area and number of producers under certification have nearly tripled over the last decade. Certified area now accounts for over 20% of the global ...

Indonesia is the world's third largest cocoa producer, but production is decreasing since 2011. We revisited cocoa farmers for an environmental assessment in Luwu Timur, Sulawesi, 7 months after a socio-economic survey on cocoa certification outcomes and observed many cocoa plantations being converted into oil palm and maize. Including our field data as well as secondary data on commodity prices and yields, we outline reasons for cocoa ...

Magnetic Resonance Imaging (MRI) often encounters image quality degradation due to magnetic field inhomogeneities. Conventional passive shimming techniques involve the manual placement of discrete magnetic materials, imposing limitations on correcting complex inhomogeneities. To overcome this, we propose a novel 3D printing method utilizing binder jetting technology to enable precise deposition of a continuous range of concentrations of ...

With growing gas and oil prices, electricity generation based on these fossil fuels is becoming increasingly expensive. Furthermore, the vision of natural gas as a transition fuel is subject to many constraints and uncertainties of economic, environmental, and geopolitical nature. Consequently, renewable energies such as solar and wind power are expected to reach new records of installed capacity over the upcoming years. Considering the above, ...

Metal-organic frameworks (MOFs) are highly porous materials, which consist of inorganic metal nodes coordinated by multitopic organic linkers. Thanks to their highly tunable chemical and structural properties, ordered pores, and high surface area, MOFs have attracted ever-growing interest in many applications. For many of these applications, such as membrane-based separations, sensors, electrocatalysis, and energy storage, it is required to ...

Patients with BRAFV600/NRASQ61 wild-type melanoma who progress after immune
checkpoint inhibitors (ICIs) have a poor prognosis. MEK inhibition has
shown activity in this patient population but is associated with treatmentlimiting
skin toxicity. Combining a BRAF inhibitor with a MEK inhibitor is
associated with less skin toxicity.
METHODS This phase II trial investigated trametinib (2 mg once daily) in patients with ...

High-precision searches for an electric dipole moment of the neutron (nEDM) require stable and uniform magnetic field environments. We present the recent achievements of degaussing and equilibrating the magnetically shielded room (MSR) for the n2EDM experiment at the Paul Scherrer Institute. We present the final degaussing configuration that will be used for n2EDM after numerous studies. The optimized procedure results in a residual magnetic ...
