Low-energy channel for mass transfer in Pt crystal initiated by molecule impact by Babicheva, Rita I., Evazzade, Iman, Korznikova, Elena A., Shepelev, Igor A., Zhou, Kun, Dmitriev, Sergey V.

“…Crystal surface bombardment by atoms or molecules, neutral or ionized, occurs both in ambient conditions and in many technological operations, such as surface plasma treatment, ion implantation, etc. Recently, it was established that the impact of a molecule initiates the mass transfer in the one-dimensional Frenkel-Kontorova atomic chain more efficiently than that of a single atom. …”

Ionic covalent organic framework based electrolyte for fast-response ultra-low voltage electrochemical actuators by Yu, Fei, Ciou, Jing-Hao, Chen, Shaohua, Poh, Wei Church, Chen, Jian, Chen, Juntong, Haruethai, Kongcharoen, Lv, Jian, Gao, Dace, Lee, Pooi See

“…Herein, we demonstrate that the actuation performance of an ionic two-dimensional covalent-organic framework based electrochemical actuator is improved through the ordered pore structure of opening up efficient ion transport routes. Specifically, the actuator shows a large peak to peak displacement (9.3 mm, ±0.5 V, 1 Hz), a fast-response time to reach equilibrium-bending (~1 s), a correspondingly high bending strain difference (0.38%), a broad response frequency (0.1-20 Hz) and excellent durability (>99%) after 23,000 cycles. …”

Monocyte-derived extracellular vesicles, stimulated by Trypanosoma cruzi, enhance cellular invasion in vitro via activated TGF‐β1 by Ansa-Addo, Ephraim A., Pathak, Paras, McCrossan, Maria V., Volpato Rossi, Izadora, Abdullahi, Mahamed, Stratton, Dan, Lange, Sigrun, Ramirez, Marcel I., Inal, Jameel

“…Host cell lEVs were released through Mtr interaction with host cell lipid raft domains, integrins, and mechanosensitive ion channels, whereupon [Ca2+]cyt increased (50 to 750 nM) within 15 s. lEV release and cell entry of T. cruzi, which increased up to 30 and 60 mpi, respectively, as well as raised actin depolymerization at 60 mpi, were all reduced by TRPC inhibitor, GsMTx‐4. …”

Spin-ice physics and phase transitions in cadmium cyanide by Coates, CS

“…This thesis explores the structural ice analogue cadmium cyanide, Cd(CN)2, a cubic negative thermal expansion (NTE) material, in which the orientation of cyanide ions maps onto the spin orientation in spin-ices. …”

Electronic structure of paramagnetic transition metal complexes by Al-Ameed, K

“…The distribution of metal ions across sites of different coordination geometry is a fundamental problem in inorganic chemistry (the text-book example is the spinel family) and we show here that the ligand-field stabilisation energy available to Ni^II dominates the site distribution. …”

Synthesis of polymeric materials derived from abundant natural feedstocks using non-toxic heavy metals by Navickaite, G

“…The conformational flexibility of the ligand was discussed in relation with varying steric demands, and the bonding environment was contrasted with related bismuth structures, which contain a +3 metal ion with a considerable size difference (<em>r</em>_Sc3+ = 0.745, <em>r</em>_Bi3+ = 1.03 Å).…”

Tunable anti-ambipolar vertical bilayer organic electrochemical transistor enable neuromorphic retinal pathway by Laswick, Zachary, Wu, Xihu, Surendran, Abhijith, Zhou, Zhongliang, Ji, Xudong, Matrone, Giovanni Maria, Leong, Wei Lin, Rivnay, Jonathan

“…Increasing demand for bio-interfaced human-machine interfaces propels the development of organic neuromorphic electronics with small form factors leveraging both ionic and electronic processes. Ion-based organic electrochemical transistors (OECTs) showing anti-ambipolarity (OFF-ON-OFF states) reduce the complexity and size of bio-realistic Hodgkin-Huxley(HH) spiking circuits and logic circuits. …”

Topochemical cation exchange reactions of Ruddlesden-Popper oxides by Conway, R

“…It was found that modulation of the Mn-site occupancy corresponds to a chequerboard ordering arrangement, which is coupled to the modulation of the equatorial oxygen ion site. MnSrNb2O7 undergoes a transition to an antiferromagnetically ordered state below TN = 39 K, in which the Mn2+ magnetic moments are orientated parallel to the z-axis in a G-type arrangement. …”

Sensorimotor control of Drosophila copulation by Herbert, MR

Tumor cell-intrinsic signals promoting tolerance and adaptation to oncogenic kinase inhibition by Flower, Cameron Timothy

“…The work described in both parts was aided by two MS software solutions I developed: one to automate the generation of targeted acquisition methods for protein phosphosites and pathways of interest, and the other to retain quantitative information from fragment ion spectra with missing values. Together, this thesis reports new connections between cell signaling and kinase inhibitor response, and offers the intriguing hypothesis that SFK signaling may be a conserved barrier for maximally effective targeted cancer therapy.…”
