Surveying the solar system by measuring angles and times: from the solar density to the gravitational constant

, 2004
A surprisingly large amount of information on our solar system can be gained from simple measurements of the apparent angular diameters of the sun and the moon. This information includes the average density of the sun, the distance between earth and moon,

DNA Origami‐Cyanine Nanocomplex for Precision Imaging of KRAS‐Mutant Pancreatic Cancer Cells

Advanced Science, EarlyView.
DNA origami‐cyanine (Do‐Cy) nanocomplexes are synthesized to selectively image KRAS‐mutant pancreatic cancer cells in the highly desmoplastic tumors. This study shows that the Do‐Cy nanocomplexes are preferentially internalized by cancer cells over other stroma cells via KRAS‐dependent macropinocytosis.

How to Weigh a Star Using a Moon

, 2010
We show that for a transiting exoplanet accompanied by a moon which also transits, the absolute masses and radii of the star, planet and moon are determinable. For a planet-star system, it is well known that the density of the star is calculable from the

Can citizen scientists provide a reliable geo-hydrological hazard inventory? An analysis of biases, sensitivity and precision for the Rwenzori Mountains, Uganda

Environmental Research Letters, 2022
Spatio-temporal inventory of natural hazards is a challenging task especially in rural or remote areas in the Global South where data collection at regional scale is difficult. Citizen science, i.e. involvement of no-experts in collecting information and

Real‐Time Wireless Detection of Heavy Metal Ions Using a Self‐Powered Triboelectric Nanosensor Integrated with an Autonomous Thermoelectric Generator‐Powered Robotic System

Advanced Science, EarlyView.
This study introduces a self‐powered environmental monitoring system that integrates a triboelectric nanosensor (TENS) with a robotic hand, controlled remotely by an exo‐hand and powered by a thermoelectric generator (TEG). The fully autonomous system detects Pb2⁺, Cr⁶⁺, and As3⁺ ions in real‐time and operates without external power, ideal for remote ...

Pressure‐Driven Reactivity in Dense Methane‐Nitrogen Mixtures

Angewandte Chemie, EarlyView.
CH4 and N2 are abundant molecules in our solar system and are the primary constituents of Titan's atmosphere. Under extreme pressures and temperatures within a diamond anvil cell, CH4 and N2 are demonstrated to react to form a range of compounds, dependent on the conditions and initial concentrations.

Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin

The Planetary Science Journal
The timing and scale of lunar tectonism provide a crucial insight into the geologic evolution of Earth’s Moon. Within the nearside lunar maria, wrinkle ridges formed during and after the emplacement of the mare basalts as a result of subsidence-induced ...

Low‐Irradiance Antimicrobial Blue Light‐Bathing Therapy for Wound Infection Control

Advanced Science, EarlyView.
Antimicrobial blue light has been shown as an appealing non‐pharmacological antimicrobial alternative. However, its clinical applications have been hindered by high irradiance‐associated photothermal risks. In this work, a low‐irradiance blue light‐bathing concept and a wearable photonic wound patch are established to address this challenge in terms of

Nanoconfinement‐Induced Electrochemical Ion‐Solvent Cointercalation in Pillared Titanate Host Materials

Angewandte Chemie, EarlyView.
Interlayer‐expansion of hydrogen tetratitanate is realized with organic pillars. Optimized atomistic configurations of the pillared materials are proposed by characterization with experiment and simulation. The nanoconfinement modification of HTO induces ion‐solvent cointercalation reactions with improved kinetics and increased storage capacity ...

Fragmenti o intertekstu pesničkog dela Stevana Pešića

Slavistična Revija, 2018
U radu je ukazano na reflekse slovenskog mitološkog nasleđa i folklorne tradicije u pesništvu Stevana Pešića. Kao semantički i ekspresivno aktivan citatni i intertekstualni sloj autorskog iskaza, mitsko i usmenopoetsko pesničko iskustvo Pešićevo delo ...
