Molecular Engineering of the Lead Iodide Perovskite Surface: Case Study on Molecules with Pyridyl Groups
We computationally
investigate the molecular engineering approach
of the lead iodide perovskite surface employing a pyridyl anchor-based
molecular adsorbate as an example. The molecular adsorption approach
on lead halide perovskite surfaces has been employed for passivation
purposes in perovskite solar cells and was demonstrated to successfully
enhance the solar cell performance in previous experimental studies.
It is an open question whether the structures and properties of the
lead halide perovskite can be further modified via the molecular engineering
approach, and this study serves to probe the molecular engineering
approach in the lead halide perovskite surface. First-principles calculations
are employed to determine the nanoscopic structure of the lead halide
perovskite surface with pyridyl anchor-based molecular adsorbates
and prove that the pyridyl anchor-based molecule resides stably on
the perovskite surface and modifies the perovskite surface structure.
In addition, the calculations demonstrate that the electronic and
optical properties of the lead halide perovskites can be controlled
by the molecular engineering method. Noteworthily, we find that the
molecular engineering approach is effective to modify the optical
properties of the lead halide perovskite layer investigated in this
study. Such molecular engineering approach on the perovskite surface
could be potentially applicable to further enhance the performance
of perovskite solar cells and perovskite-based optoelectronic devices
Probing Electronic Doping of Single-Walled Carbon Nanotubes by Gaseous Ammonia with Dielectric Force Microscopy
The electronic properties of single-walled carbon nanotubes
(SWNTs)
are sensitive to the gas molecules adsorbed on nanotube sidewalls.
It is imperative to investigate the interaction between SWNTs and
gas molecules in order to understand the mechanism of SWNT-based gas-sensing
devices or the stability of individual SWNT-based field effect transistors
(FETs). To avoid the Schottky barrier at the metal/SWNT contact, which
dominates the performance of SWNT-based FETs, we utilize a contactless
technique, dielectric force microscopy (DFM), to study the intrinsic
interaction between SWNTs and gaseous ammonia molecules. Results show
that gaseous ammonia affects the conductivity of semiconducting SWNTs
but not metallic SWNTs. Semiconducting SWNTs, which are p-type doped
in air, show suppressed hole concentration in ammonia gas and are
even inverted to n-type doping in some cases

CD146 Deletion in the Nervous System Impairs Appetite, Locomotor Activity and Spatial Learning in Mice
<div><p>Cell adhesion molecules (CAMs) are crucial effectors for the development and maintenance of the nervous system. Mutations in human CAM genes are linked to brain disorders and psychological diseases, and CAM knockout mice always exhibit similar behavioral abnormalities. CD146 is a CAM of the immunoglobulin superfamily that interacts with Neurite Outgrowth Factor and involved in neurite extension <i>in vitro</i>. However, little is known about its <i>in vivo</i> function in the nervous system. In this study, we used a murine CD146 nervous system knockout (CD146<sup>ns-ko</sup>) model. We found that the brains of some CD146<sup>ns-ko</sup> mice were malformed with small olfactory bulbs. CD146<sup>ns-ko</sup> mice exhibited lower body weights and smaller food intake when compared with wild type littermates. Importantly, behavior tests revealed that CD146<sup>ns-ko</sup> mice exhibited significant decreased locomotor activity and impaired capacity for spatial learning and memory. Our results demonstrate that CD146 is important for mammalian nervous system development and proper behavior patterns.</p></div

Knockout of CD146 in the nervous system impaired spatial learning and memory in mice.
<p>(A) WT and CD146<sup>ns-ko</sup> mice at the age of 1 month were subjected to the Morris water maze test. During the 7-day training period, time spent in finding the target of each mouse was recorded and analyzed with a repeated measures ANOVA. At the last day of probe test, distance swam (B) and time spent in each quadrant by the mice (C) were recorded and analyzed with Student’s t test. The brains of 1-month-old WT and CD146<sup>ns-ko</sup> mice were sagittally sectioned. The hippocampal area (D) and neuron density of CA1, CA3 and DG (E) were measured after Nissl staining. Data is presented as means ± SEM.</p
