2D trajectories of human pluripotent stem cell colonies
<p>This dataset is a part of the following manuscript submitted for publication in Life (MDPI):</p> <p>"Human Pluripotent Stem Cell Colony Migration is Related to Culture Environment and Morphological Phenotype"<br>by Vitaly V. Gursky, Alina S. Chabina, Olga A. Krasnova, Anastasiya A. Kovaleva, Daria V. Kriger, Michail S. Zadorsky, Konstantin N. Kozlov, and Irina E. Neganova</p> <p>A trajectory in the csv file is an array of the 2D coordinates {{x1,y1}, {x2,y2}, ...} (in µm; centered at {x,y}={0,0}), which represent the migration history of the center of one cell colony. Trajectories were obtained from the time-lapse bright-field images, using the Manual Tracking tool in ImageJ (Fiji). The data were collected for colonies from three human pluripotent stem cell lines (human induced pluripotent stem cell line AD3, patient specific human induced pluripotent stem cell line HPCASRi002-A (CaSR), and human embryonic stem cell line H9), grown under two culture conditions (media/matrix = mTESR1/MG or E8/GT). The colonies were phenotyped according to their morphological characteristics associated with the pluripotency status ("good" and "bad" phenotype); cells with the "bad" phenotype showed signs of incipient differentiation. The time interval between adjacent coordinates is 15 min.</p> <p>The data were obtained under the financial supprot of the Russian Science Foundation, grant number 21-75-20132.</p>

2D-Raman-THz Spectroscopy with Single-Shot THz Detection
<p>We present a 2D-Raman-THz setup with multichannel (single-shot) THz detection, utilizing two crossed echelons, in order to reduce the acquisition time of typical 2D-Raman-THz experiments from days to a few hours. This speed-up is obtained in combination with a high repetition rate (100 kHz) Yb-based femtosecond laser system and a correspondingly fast array detector. The wavelength of the Yb-laser (1030 nm) is advantageous, since it assures almost perfect phase matching in GaP for THz generation and detection, and since dispersion in the transmissive echelons is minimal. 2D-Raman-THz test measurements on liquid bromoform (CHBr3) are reported. An enhancement of ∼5.8 times in signal-to-noise ratio is obtained for single-shot detection when comparing to conventional step scanning measurements in the THz time-domain, corresponding to speed up of acquisition time of 34.</p>

Hot carrier extraction from 2D semiconductor photoelectrodes
<p>Hot carrier-based energy conversion systems could double the efficiency of conventional solar energy technology or drive photochemical reactions that would not be possible using fully thermalized, "cool" carriers, but current strategies require expensive multi-junction architectures. Using an unprecedented combination of photoelectrochemical and in situ transient absorption spectroscopy measurements, we demonstrate ultrafast (<50 fs) hot exciton and free carrier extraction under applied bias in a proof-of-concept photoelectrochemical solar cell made from earth-abundant and potentially inexpensive monolayer (ML) MoS<sub>2</sub>. Our approach facilitates ultrathin 7 Å charge transport distances over 1 cm<sup>2</sup> areas by intimately coupling ML-MoS<sub>2</sub> to an electron-selective solid contact and a hole-selective electrolyte contact. Our theoretical investigations of the spatial distribution of exciton states suggest greater electronic coupling between hot exciton states located on peripheral S atoms and neighboring contacts likely facilitates ultrafast charge transfer. Our work delineates future 2D semiconductor design strategies for practical implementation in ultrathin photovoltaic and solar fuels applications.</p>
