The compression behavior of [Rb(18-crown-6)][SbCl6] crystal under pressure up to 2.16 (3) GPa was investigated in a diamond anvil cell (DAC) using a mixture of pentane–iso­pentane (1:4) as the pressure-transmitting fluid. The compound crystallizes in trigonal space group R3 and no phase transition was observed in the indicated pressure range. The low value of pressure bulk modulus [9.1 (5) GPa] found in this crystal is a characteristic of soft materials with predominant dispersive and electrostatic interaction forces. The nonlinear relationship between unit-cell parameters under high pressure is attributed to the influence of reduced intermolecular H⋯Cl contacts under pressure over 0.73 GPa. It also explains the high compression efficiency of [Rb(18-crown-6)][SbCl6] crystals at relatively low pressures, resulting in a significant shift of the Rb atom to the center of the crown ether cavity. At pressures above 0.9 GPa, steric repulsion forces begin to play a remarkable role, since an increasing number of interatomic H⋯Cl and H⋯H contacts become shorter than the sum of their van der Waals (vdW) radii. Below 0.9 GPa, both unit-cell parameter dependences (P–a and P–c) exhibit hysteresis upon pressure release, demonstrating their influence on the disordered model of Rb atoms. The void reduction under pressure also demonstrates two linear sections with the inflection point at 0.9 GPa. Compression of the crystal is accompanied by a significant decrease in the volume of the voids, leading to the rapid approach of Rb atoms to the center of the crown ether cavity. For the Rb atom to penetrate into the center of the crown ether cavity in [Rb(18-crown-6)][SbCl6], it is necessary to apply a pressure of about 2.5 GPa to disrupt the balance of atomic forces in the crystal. This sample serves as a compression model demonstrating the influence of both attractive and repulsive forces on the change in unit-cell parameters under pressure.

SnGe4N4O4 was synthesized at high pressure (16 and 20 GPa) and high temperature (1200 and 1500°C) in a large-volume press. Powder X-ray diffraction experiments using synchrotron radiation indicate that the derived samples are mixtures of known and unknown phases. However, the powder X-ray diffraction patterns are not sufficient for structural characterization. Transmission electron microscopy studies reveal crystals of several hundreds of nanometres in size with different chemical composition. Among them, crystals of a previously unknown phase with stoichiometry SnGe4N4O4 were detected and investigated using automated diffraction tomography (ADT), a three-dimensional electron diffraction method. Via ADT, the crystal structure could be determined from single nanocrystals in space group P63mc, exhibiting a nolanite-type structure. This was confirmed by density functional theory calculations and atomic resolution scanning transmission electron microscopy images. In one of the syntheses runs a rhombohedral 6R polytype of SnGe4N4O4 could be found together with the nolanite-type SnGe4N4O4. The structure of this polymorph was solved as well using ADT.

This study reports the synthesis and crystal structure determination of a novel CrTe3 phase using various experimental and theoretical methods. The average stoichiometry and local phase separation of this quenched high-pressure phase were characterized by ex situ synchrotron powder X-ray diffraction and total scattering. Several structural models were obtained using simulated annealing, but all suffered from an imperfect Rietveld refinement, especially at higher diffraction angles. Finally, a novel stoichiometrically correct crystal structure model was proposed on the basis of electron diffraction data and refined against powder diffraction data using the Rietveld method. Scanning electron microscopy–energy-dispersive X-ray spectrometry (EDX) measurements verified the targeted 1:3 (Cr:Te) average stoichiometry for the starting compound and for the quenched high-pressure phase within experimental errors. Scanning transmission electron microscopy (STEM)–EDX was used to examine minute variations of the Cr-to-Te ratio at the nanoscale. Precession electron diffraction (PED) experiments were applied for the nanoscale structure analysis of the quenched high-pressure phase. The proposed monoclinic model from PED experiments provided an improved fit to the X-ray patterns, especially after introducing atomic anisotropic displacement parameters and partial occupancy of Cr atoms. Atomic resolution STEM and simulations were conducted to identify variations in the Cr-atom site-occupancy factor. No significant variations were observed experimentally for several zone axes. The magnetic properties of the novel CrTe3 phase were investigated through temperature- and field-dependent magnetization measurements. In order to understand these properties, auxiliary theoretical investigations have been performed by first-principles electronic structure calculations and Monte Carlo simulations. The obtained results allow the observed magnetization behavior to be interpreted as the consequence of competition between the applied magnetic field and the Cr–Cr exchange interactions, leading to a decrease of the magnetization towards T = 0 K typical for antiferromagnetic systems, as well as a field-induced enhanced magnetization around the critical temperature due to the high magnetic susceptibility in this region.

High-pressure neutron powder diffraction data from PbNCN were collected on the high-pressure diffraction beamline SNAP located at the Spallation Neutron Source (SNS) of Oak Ridge National Laboratory (Tennessee, USA). The diffraction data were analyzed using the novel method of multidimensional (two dimensions for now, potentially more in the future) Rietveld refinement and, for comparison, employing the conventional Rietveld method. To achieve two-dimensional analysis, a detailed description of the SNAP instrument characteristics was created, serving as an instrument parameter file, and then yielding both cell and spatial parameters as refined under pressure for the first time for solid-state cyanamides/carbodi­imides. The bulk modulus B0 = 25.1 (15) GPa and its derivative B'0 = 11.1 (8) were extracted for PbNCN following the Vinet equation of state. Surprisingly, an internal transition was observed beyond 2.0 (2) GPa, resulting from switching the bond multiplicities (and bending direction) of the NCN2− complex anion. The results were corroborated using electronic structure calculation from first principles, highlighting both local structural and chemical bonding details.

Facebook and Instagram users in Europe will get the option to see less personalized ads if they don’t want to pay for an ad-free subscription, social media company Meta said Tuesday, bowing to pressure from Brussels over privacy and digital competition concerns.

Meta Platforms has been offering European Union an ad-free subscription option for about a year to comply with the continent’s strict data privacy rules, but regulators had accused the company of giving people a false choice.

The company said in a blog post that while people will still be able to choose between the subscription and existing free versions, it would also start giving free users an extra option over the coming weeks to see digital ads that are less personalized.

This means ads will be targeted at users based only on what they see during their current session on Facebook or Instagram going back no more than two hours, plus minimal personal information such as age, location, gender as well as how they engage with ads.

Data from all of a user’s previous time spent on Facebook or Instagram, which is typically combined to precisely target an individual with tailored ads, won’t be used.

“While this new choice is designed to give people an additional control over their data and ad experience, it may result in ads that are less relevant to a person’s interests,” Meta said in a blog post. “That means people will see ads that they don’t find as interesting. This drop in relevance is inevitable given that drastically reduced data is being used to show these less personalized ads to people.”

People who choose the new option will see ad breaks that can’t be skipped for a few seconds, Meta said.

European Union regulators had accused Meta of breaching the 27-nation bloc’s digital rules when it gave user the option to pay a monthly fee to avoid being targeted by ads based on their personal data.

The U.S. tech giant had rolled out the option after the European Union’s top court ruled Meta must first get consent before showing ads to users, in a decision that threatened its business model of tailoring ads based on individual users’ online interests and digital activity.

The company also said Tuesday it’s slashing monthly subscription prices for the ad-free option. Web users will pay 5.99 euros ($6.36), down from 9.99 euros previously, while iPhone and Android users will be charged 7.99 euros instead of 12.99 euros, which includes commissions charged by the Apple and Google mobile app stores.

Meta’s new subscription model could hit the company’s lucrative digital ad business in one of its biggest markets. The company said it has already factored the new offering into its most recent business outlook and financial guidance.

The options are available to users 18 and older in the EU’s 27 member countries, plus Switzerland, Norway, Iceland and Liechtenstein.

The European Union has notified Apple that it may be violating EU anti-geo-blocking regulations with practices regarding its media services, giving the company one month to respond.


The European Commission, in conjunction with the Consumer Protection Cooperation (CPC) Network, today announced that it has formally notified Apple regarding potential breaches of the EU's anti-geo-blocking rules. This follows an investigation led by national consumer authorities from Belgium, Germany, and Ireland, coordinated by the European Commission. According to the Commission, Apple's practices appear to unlawfully restrict European consumers from accessing digital content based on their country of residence.

According to the CPC Network, consumers using Apple Media Services, such as the App Store, Apple Music, and Apple TV+, encounter different interfaces and content depending on their country of registration. This regional segmentation allegedly makes it difficult, if not impossible, for users to switch between country-specific versions of Apple's services, which may be in violation of the EU's Geo-blocking Regulation enacted in 2018, designed to protect the Digital Single Market.

A significant point of concern for the EU authorities are restrictions on downloading apps. The investigation found that the ‌App Store‌ does not allow users to download apps available in other EU countries. The EU maintains that consumers should be able to access and download apps offered in other EU/EEA countries when traveling or staying temporarily in another member state.

Consumers are also only permitted to use credit or debit cards issued in the country where their Apple account was created. The Commission argues that consumers should be able to use any EU-issued payment method without facing unnecessary barriers.

Apple has been given one month to formally respond to the Commission's findings and to propose potential commitments to align its practices with EU regulations. If Apple does not adequately address the concerns raised by the CPC Network, the company may face enforcement actions. The European Commission's latest action against Apple is part of a broader push to ensure that tech giants operating within the EU comply with the bloc's regulatory frameworks.
