„OARECUM”. DESPRE MODELUL POLONEZ ÎN TRANZIȚIA ROMÂNEASCĂ (1990-1992)

Analele Universităţii din Craiova seria Istorie
“I like to look at Romania in the Polish mirror, and at Poland in the Romanian mirror” Adam Michnik once said at a conference in Bucharest. Beyond the vividness of the phrasing, this approach can prove very useful historically, especially concerning the transition from communism to democracy and a market economy.

Pure Deep Red Electroluminescence in Mixed Phase Quasi-2D Tin Iodide Perovskite Heterostructure. [PDF]

Small
Mixed‐cation quasi‐2D tin iodide perovskites show promise for deep red to NIR LEDs. Despite forming mixed n = 1, 2, and ∞ phases, pure deep red electroluminescence (≈700 nm) from the n = 2 phase is achieved by tuning cation ratios. Selective charge transport and cascade energy transfer enable phase‐selective emission. Abstract Mixed cation quasi‐2D tin

Chloride Double Perovskites Doped With Sb³⁺/Er³⁺ as Stable and Effective Luminescence Material in the Vis-NIR Region. [PDF]

Chemistry
The luminescence properties of Sb3+/Er3+‐doped chloride double perovskites Cs2Ag0.4Na0.6InCl6 have been investigated across 250‐1600 nm. Structural and spectroscopic analyses have been performed using XRD, SEM, Raman, XPS, and ToF‐SIMS methods. Energy transfer from Sb3+ to Er3+ enables emission at 525, 552, 665, 805 and 1540 nm.

Atomically Precise Ruddlesden-Popper Faults Induced Enhanced Emission in Ligand Stabilized Mixed Halide Perovskites. [PDF]

Adv Mater
This study overcomes challenges in visualizing atomic‐level defects in perovskite nanocrystals, promising to significantly improve the stability and performance of quantum dot‐based light‐emitting devices. Using double‐Cs‐corrected transmission electron microscopy, the study enables atomic‐resolution imaging of elusive RuddlesdenPopper faults hidden ...

Effects of connection to nature on residents’ perceptions of conservation policy justice of Natura 2000

Conservation Biology, Volume 36, Issue 5, October 2022., 2022
Abstract We examined the effects of human connection to nature on residents’ concerns about justice in conservation policies of Natura 2000. Expansion of Natura 2000 conservation network has resulted in local communities having to consider Natura 2000 in their development plans, and justice concerns have been strong in some communities near Natura 2000

Catholic Intimacies: Negotiating Contraception in Late Communist Poland

Journal of Religious History, Volume 46, Issue 3, Page 483-502, September 2022., 2022
The majority of people in Poland self‐identified as Catholic throughout the second half of the twentieth century. Despite the Polish Episcopate's unanimous rejection of contraception as immoral and sinful, a considerable proportion of Polish Catholics utilized family planning techniques and technologies explicitly banned by their institutional Church ...

Mechanochemical Transformation of CF3 Group: Synthesis of Amides and Schiff Bases

Advanced Synthesis &Catalysis, Volume 363, Issue 24, Page 5448-5460, December 21, 2021., 2021
Abstract We communicate two mild, solvent‐free mechanochemical coupling transformations of CF3 group with nitro compounds into amides or Schiff bases employing Ytterbia as a catalyst. This process proceeds via C−F bond activation, accompanied with utilisation of Si‐based reductants/oxygen scavengers – reductants of the nitro group.

A new sediment-dwelling pholadid bivalve from Oligocene glaciomarine sediments of King George Island, West Antarctica [PDF]

Acta Palaeontologica Polonica, 2016
We present a re-description of the pholadid bivalve from the Oligocene Polonez Cove Formation, King George Island, West Antarctica, previously identified as Penitella sp. The study is based on a collection of 210 specimens, preserved exclusively in life

ANU productions and the performance of otherness

Orbis Litterarum, Volume 76, Issue 6, Page 301-310, December 2021., 2021
Abstract Taking my lead from Ric Knowles’s analysis of interculturalism 'from below’ (Knowles, 2017, 2), the focus of this essay is on the representation of ‘otherness’ in three productions of Ireland’s multi‐award‐winning company ANU Productions: their 2014 play Vardo about ‘travellers’ in an inner‐city community; their 2016 play Sunder, in which ...

Elevated temperatures drive the evolution of armour loss in the threespine stickleback Gasterosteus aculeatus

Functional Ecology, Volume 35, Issue 8, Page 1735-1744, August 2021., 2021
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract While there is evidence of genetic and phenotypic responses to climate change, few studies have demonstrated change in functional traits with a known genetic basis.
