In the context of the current 21st century globalization processes, the author raises the significance of reflection articulated on the part of the post-communistand post-totalitarian communities, the integrating European Union and its member states. This importance stems from the necessity to consider contemporary integration processes from all angles, and not to concentrate only on the intellectual vision of both the European and American West, so apparently permeated with one-sidedness of interpretation. As it seems, the intellectuals of the West fail to notice the gravity of the fact that secular equivalents of religiousness, which are totalitarianism and western consumer capitalism, have become a mere caricature of human aspirations and ideals, thus distorting intellectual bases of consecutive stages of globalization. The reflection of the article has been contained in three parts. In its first part the author characterises the rising topicality of globalization. Next, he raises the necessity to differentiate between various human communities in the analyses on the current stage of globalization processes. Thus, he recognizes the importance to identify different stages of human communities' historical development, which due to an enormous progress in technology had to face the reality of globalization. Last but not least, the author attempts to outline the possibilities to overcome ideological helplessness concerning the issue of socio-ecological problems resulting from the globalization processes in the continental diversity of cultural religious local communities. ; W kontekście aktualnych procesów globalizacyjnych współczesności początków XXI stulecia autor podnosi doniosłość wyartykułowywanej refleksji także ze strony społeczności postkomunistycznych i posttotalitarnych, integrującej się Unii Europejskiej i jej państw członkowskich. Doniosłość wynika z konieczności podjęcia refleksji, która nie byłaby naznaczona jednostronnością postrzegania oraz interpretowania współczesnych procesów integracyjnych, jaką zdaje się być przeniknięta myśl intelektualna Zachodu europejskiego i zaatlantyckiego. Bowiem refleksja czyniona przez intelektualistów Zachodu zdaje się nie wychwytywać ważności faktu, że świeckie zamienniki religijności, czyli totalitaryzm i zachodni konsumpcjonistyczny kapitalizm, stały się zaledwie karykaturąludzkich aspiracji oraz ideałów, powodując z kolei wypaczanie się intelektualnych koncepcji, stanowiących podstawę kształtowania kolejnych etapów mondializacji.Refleksja artykułu została rozwinięta w trzech etapach. W pierwszym autor podjął próbę scharakteryzowania potęgującej się aktualności zagadnienia globalizacyjnego.W drugim etapie refleksji skoncentrował się na podniesieniu konieczności rozróżnień w analizach stanu ludzkich społeczności na obecnym etapie procesu globalizacyjnego. Podniósł ważność rozpoznania zróżnicowania etapów rozwoju historycznego ludzkich społeczności, które zostały zastane przez globalizacyjną równoczesność, wynikłą z możliwości techniczno-technologicznych. Natomiast w etapie trzecim i ostatnim podjął próbę zarysowania możliwości przezwyciężenia bezradności ideologicznych wizji w sprawie rozwiązania kwestii społecznych w konsekwencjach społeczno-ekologicznych procesów mondializacyjnych w zróżnicowaniu kontynentalnych lokalności kulturowo-religijnych.

Quantum-confined CsPbBr3 nanoplatelets (NPLs) are extremely promising for use in low-cost blue light-emitting diodes, but their tendency to coalesce in both solution and film form, particularly under operating device conditions with injected charge-carriers, is hindering their adoption. We show that employing a short hexyl-phosphonate ligand (C6H15O3P) in a heat-up colloidal approach for pure, blue-emitting quantum-confined CsPbBr3 NPLs significantly suppresses these coalescence phenomena compared to particles capped with the typical oleyammonium ligands. The phosphonate-passivated NPL thin films exhibit photoluminescence quantum yields of ∼40% at 450 nm with exceptional ambient and thermal stability. The color purity is preserved even under continuous photoexcitation of carriers equivalent to LED current densities of ∼3.5 A/cm2. 13C, 133Cs, and 31P solid-state MAS NMR reveal the presence of phosphonate on the surface. Density functional theory calculations suggest that the enhanced stability is due to the stronger binding affinity of the phosphonate ligand compared to the ammonium ligand. ; J.

Hybrid perovskite-based optoelectronic devices are demonstrating unprecedented growth in performance, and defect passivation approaches are highly promising routes to further improve properties. Here, the effect of the molecular ion BF4-, introduced via methylammonium tetrafluoroborate (MABF4) in a surface treatment for MAPbI3 perovskite is reported. The optical spectroscopic characterisations shows that the introduction of tetrafluoroborate leads to reduced non-radiative charge carrier recombination with a reduction in first order recombination rate from 6.5 × 106 to 2.5 × 105 s-1 in BF4--treated samples, and a consequent increase in photoluminescence quantum yield by an order of magnitude (from 0.5% to 10.4%). 19F, 11B and 14N solid-state NMR is used to elucidate the atomic-level mechanism of the BF4- additive-induced improvements, revealing that the BF4- acts as a scavenger of excess MAI by forming MAI–MABF4 cocrystals. This shifts the equilibrium of iodide concentration in the perovskite phase is presumably due to the formation of MAI-MABF4 cocrystal, thereby reducing the concentration of interstitial iodide defects that act as deep traps and non-radiative recombination centers. These collective results allow us, for the first time, to elucidate the microscopic mechanism of action of BF4-. ; S.N. would like to acknowledge Royal Society-SERB Newton International Fellowship for funding.
