Delocalized Davydov D1 Ansatz for the Holstein polaron by Sun, Jin, Duan, Liwei, Zhao, Yang

“…Unique solutions are obtained with the delocalized D1 for different initial conditions when the transfer integral is 20 times the phonon frequency at the zone center, implying the absence of any self-trapping discontinuity. The scaled correlation variance is found to fit satisfactorily well with the predictions of the perturbation theories.…”

Characterising the iron dependence of T-cells by Teh, MR

“…Interestingly, exogenous aspartate substantially rescues the proliferation of iron deprived CD8+ T-cells suggesting that endogenous aspartate sources are unusable, possibly due to trapping of aspartate within the mitochondria. Overall, this thesis demonstrates that iron deprivation impairs T-cell biochemistry at multiple nodes providing insight as to how metabolic and iron modulatory interventions could be coupled to augment or suppress immunity.…”

Range expansion of a declining forest species, the Western Gray Squirrel (Sciurus griseus), into semi-arid woodland by Sultaire, SM, Montgomery, RA, Jackson, PJ, Millspaugh, JJ

“…Using a network of remote camera traps deployed across the Sierra Nevada–Great Basin ecotone in northwestern Nevada, we detected western gray squirrels across 16 of 100 camera-trapping sites. …”

A diminished large carnivore guild with contrasting species-habitat associations persists outside national parks in Namibia's central-eastern landscape by Verschueren, S, Hofmann, T, Briers-Louw, WD, Kakove, M, Leirs, H, Bauer, H, Marker, L, Cristescu, B

“…Through targeted searches for intensive-use areas and pooling detections across camera trap stations, we reliably detected the most elusive carnivores. …”

Experimental investigation on the effect of masked multiple passes abrasive waterjet machining surface texturing on coefficient of friction by Hafiz, Husin, Mohd Nazir, Mat Nawi, Asmelash, Mebrahitom Asmelash, Kushendarsyah, Saptaji, Azmir, Azhari

“…According to the findings, there is less friction in craters with greater densities because there are more craters in the contact zone, which improves the trapping of debris particles and reduces friction, when the crater density rises from 4% to 18%, there is a greater chance of worn debris becoming trapped, which reduces friction. …”

Development of a perfusable, hierarchical microvasculature-on-a-chip model by Chen, Sophia W., Blazeski, Adriana, Zhang, Shun, Shelton, Sarah E., Offeddu, Giovanni S., Kamm, Roger D.

“…Circulating cells were found to arrest in areas conducive to physical trapping or areas with the least amount of shear stress, consistent with hemodynamic or mechanical theories of metastasis. …”

Molybdenum disulfide (MoS_2) as a broadband saturable absorber for ultra-fast photonics by Zhang, H, Lu, S B, Zheng, J, Du, J, Wen, S C, Tang, D Y, Loh, K P

“…To explore its potential applications in ultrafast photonics, we fabricated a passive mode locker for ytterbium-doped fibre laser by depositing few-layered MoS2 onto the end facet of optical fiber by means of an optical trapping approach. Our laser experiment shows that few-layer MoS2-based mode locker allows for the generation of stable mode-locked laser pulse, centered at 1054.3 nm, with a 3-dB spectral bandwidth of 2.7 nm and a pulse duration of 800 ps. …”

Probing the toxicity mechanism of multiwalled carbon nanotubes on bacteria by Hartono, Maria Regina, Kushmaro, Ariel, Chen, Xiaodong, Marks, Robert S.

“…Using a field-emission scanning electron microscope, we demonstrated that membrane damage is caused largely by MWCNTs trapping bacteria and piercing the cell walls. As a result of our observations, we propose integrating MWCNTs and bacteria degradation for pollutant removal in nutrient-rich media to minimize the toxicity effect of CNTs.…”

Cathode material investigation towards high-performance aluminum batteries by Gong, Xuefei

Electrochromic smart window for modulation of infrared heat by Loke, Jie Yi

“…The improved electrochromic performance is due the existence of Nd-Mo co-dopants that restrict the trapping of Li+ ions within the α-WO3 framework. This reduces the degree of crystallization of α-WO3 layer and improves the electronic conductivity by transferring excess electrons to the conduction band of the SnO2. …”

Ultralow-threshold two-photon pumped amplified spontaneous emission and lasing from seeded CdSe/CdS nanorod heterostructures by Xing, Guichuan, Liao, Yile, Wu, Xiangyang, Chakrabortty, Sabyasachi, Liu, Xinfeng, Yeow, Edwin Kok Lee, Sum, Tze Chien, Chan, Yinthai

“…Ultrafast optical spectroscopy verified that while the Auger processes in these heterostructures are indeed suppressed, ASE in these samples could also be strongly affected by a fast hole trapping process to the NR surface states. Lastly, to exemplify the potential of these seeded CdSe/CdS nanodot/nanorod heterostructures as a viable gain media for achieving two-photon lasing, a highly photostable microsphere laser with an ultralow pump threshold is showcased.…”
