High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Preliminary archaeological and dendrochronological researches at the pile-dwelling settlement Veliki Otavnik Ib near Bistra

open access: yes, 2009
In 2006, we discovered remains of a pile-dwelling settlement Veliki Otavnik Ib during underwater survey of the riverbed of the Bistra stream at the Ljubljansko barje, not far from the foot of the mountainous Karstic fringe.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Two decades of dendrochronology in the pile dwellings of the Ljubljansko barje, Slovenia

open access: yes, 2013
Systematical excavations and interdisciplinary research have been performed in prehistoric pile dwelling sites of the Ljubljansko barje in Slovenia since 1995. Wood from 16 sites has been collected for wood identification, dendrochronology and radiocarbon dating.

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

The zooarchaeological findings of birds in ancient pile dwelling at Ljubljansko barje

open access: yesAcrocephalus, 2004
Predstavljene so zooarheološke najdbe avifavne na območju Ljubljanskega barja (osrednja Slovenija). Seznam obsega 36 vrst ptic iz 9 redov. Domnevno gre za kostne akumulacije kuhinjskih ostankov koliščarjev, ki so živeli na Barju od konca mlašje kamene dobe, v bakreni ter zgodnji bronasti dobi, od prve polovice 5. do prve polovice 2. tisočletja pr.

The pile dwelling of Tombola di Cerea (Verona) (1999 excavation)

open access: yesIpoTESI di Preistoria, 2018
The pile dwelling was discovered in 1955 in the valley of the river Menago, just a few hundred meters south of the settlement of Tombola di Cerea (VR). A first excavation was carried out that very year by Francesco Zorzi, director of the Museo Civico di Storia Naturale of Verona; the digging has been resumed in 1999 by the Soprintendenza Archeologica ...

Lake dwellings in the east and southeast baltic region in the early metal period: types and reconstruction possibilities.

open access: yes, 2014
Investigations of lake-dwellings in the Eastern and southeastern part of Baltic region, inspirited by the investigations in Zurich lake (Switzerland), started in XIX th century, like in the rest part of Europe.

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

open access: yesAdvanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...
