The role of low-volatility organic compounds in initial particle growth in the atmosphere / Tröstl, Jasmin ; Chuang, Wayne K. ; Gordon, Hamish ; Heinritzi, Martin ; Yan, Chao ; Molteni, Ugo ; Ahlm, Lars ; Frege, Carla ; Bianchi, Federico ; Wagner, Robert et al.
About half of present-day cloud condensation nuclei originate from atmospheric nucleation, frequently appearing as a burst of new particles near midday1. Atmospheric observations show that the growth rate of new particles often accelerates when the diameter of the particles is between one and ten nanometres2, 3. [...]

Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic radiative forcing of the climate, yet remain poorly understood1. Globally, around half of cloud condensation nuclei originate from nucleation of atmospheric vapours2. [...]

On The Relativity of Redshifts: Does Space Really "Expand"? / Lewis, Geraint F
In classes on cosmology, students are often told that photons stretch as space expands, but just how physical is this picture? Does space really expand? In this article, we explore the notion of the redshift of light with Einstein's general theory of relativity, showing that the core underpinning principles reveal that redshifts are both simpler and more complex than you might naively think. This has significant implications for the observed redshifting of photons as they travel across the universe, often refereed to as the cosmological redshift, and for the idea of expanding space..

Absence of equilibrium chiral magnetic effect / Zubkov, M A
We analyse the $3+1$ D equilibrium chiral magnetic effect (CME). We apply derivative expansion to the Wigner transform of the two - point Green function. [...]

On the recurrence and Lyapunov time scales of the motion near the chaos border / Shevchenko, Ivan I
Conditions for the emergence of a statistical relationship between $T_r$, the chaotic transport (recurrence) time, and $T_L$, the local Lyapunov time (the inverse of the numerically measured largest Lyapunov characteristic exponent), are considered for the motion inside the chaotic layer around the separatrix of a nonlinear resonance. When numerical values of the Lyapunov exponents are measured on a time interval not greater than $T_r$, the relationship is shown to resemble the quadratic one. [...]

Synthesis of optical spring potentials in optomechanical systems / Slatyer, Harry J ; Guccione, Giovanni ; Cho, Young-Wook ; Buchler, Ben C ; Lam, Ping Koy
We propose a method to tailor the potential experienced by a moveable end mirror in a cavity optomechanical system by specifying the spectral properties of the input field. We show that by engineering the power spectral density of the cavity input field a desired force function can be approximated, with the accuracy of the approximation limited only by the linewidth of the cavity.

Gas sensing properties of multiwall carbon nanotubes decorated with Rh nanoparticles / Leghrib, Radouane ; Dufour, Thierry ; Demoisson, Frédéric ; Claessens, Nicolas ; Reniers, François ; Llobet, Eduard
In the present work, multiwalled carbon nanotubes were decorated with rhodium nanoparticles using a colloidal solution in the post-discharge of an RF atmospheric plasma of argon (Ar) or argon/oxygen (Ar:O$_2$). The properties of these hybrid materials towards the room temperature detection of NO$_2$, C$_2$H$_4$, CO, C$_6$H$_6$ and moisture were investigated and discussed in view of compositional and morphological studies.

Streaming potential modeling in fractured rock: Insights into the identification of hydraulically active fractures / Roubinet, D ; Linde, N ; Jougnot, D ; Irving, J
Numerous field experiments suggest that the self-potential (SP) geophysical method may allow for the detection of hydraulically active fractures and provide information about fracture properties. However, a lack of suitable numerical tools for modeling streaming potentials in fractured media prevents quantitative interpretation and limits our understanding of how the SP method can be used in this regard.
