Development of ultra-thin polyethylene balloons for high altitude research upto mesosphere [PDF]

arXiv, 2014
Ever since its inception four decades back, Balloon Facility of Tata Institute of Fundamental Research (TIFR), Hyderabad has been functioning with the needs of its user scientists at its focus. During the early nineties, when the X-ray astronomy group at TIFR expressed the need for balloons capable of carrying the X-ray telescopes to altitudes up to 42

Extremal graphs for odd-ballooning of bipartite graphs [PDF]

arXiv, 2022
Given a graph $H$ and an odd integer $t$ ($t\geq 3$), the odd-ballooning of $H$, denoted by $H(t)$, is the graph obtained from replacing each edge of $H$ by an odd cycle of length at least $t$ where the new vertices of the cycles are all distinct. In this paper, we determine the range of Tur\'{a}n numbers for odd-ballooning of bipartite graphs when $t ...

Metal–Organic Framework‐Based Antimicrobial Touch Surfaces to Prevent Cross‐Contamination

Advanced Materials, EarlyView.
A MOF‐based antimicrobial door handle cover is developed. It completely inhibits the cross‐contamination of Gram‐positive bacterial species (Staphylococcus aureus, and Enterococcus faecalis), Gram‐negative bacterial species (Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii), and fungi (Candida albicans). Abstract Infection diseases

SABAT: the "Sapienza" Balloon Trajectory Simulation Code [PDF]

arXiv, 2018
We present SABAT ("Sapienza" Balloon Trajectory Simulation Code), a Fortran software for the simulation of zero-pressure scientific balloon trajectories at stratospheric altitudes. Particular attention is made to the correct reproduction of the balloon ascending phase to the floating altitude.

Tribenzyl Organic Cations Carried Multidentate X‐Type Lewis Soft Base for High‐Performance Foldable Perovskite Light‐Emitting Diodes

Advanced Materials, EarlyView.
This study proposes tribenzyl organic cation carried multidentate X‐type Lewis soft base to enhance adhesion and passivate defects simultaneously, aiming to achieve foldable and efficient perovskite nanocrystal‐based light‐emitting diodes. The resulting pure red F‐PeLEDs exhibit a recorded high EQE of 16.2% and robust mechanical properties to endure ...

Impermeable and Elastic Polydimethylsiloxane Film by Parylene‐Caulking for Inflatable Soft Devices

Advanced Materials Interfaces, EarlyView.
This study investigates poly‐para‐xylylene (parylene)‐caulking of polydimethylsiloxane (PDMS) without loss of its elasticity for use in inflatable soft devices such as a pneumatic balloon actuator (PBA). This study reports updated results using time‐of‐flight secondary ion mass spectrometry and the dependence of characteristics on prepolymer ratio ...
