Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments

Figure 3 from “Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments” by Miguel Cantero et al.: Treatment of TGEV with IGEPAL 0.2% (A). Topographical images before (left) and after (right) IGEPAL treatment (B). Profiles traced over the particles before (black) and after (blue) the treatment. The time interval between images was ~30 s (C). Height distribution of TGEV particles before (black) and after (blue) treatment (n = 103). Counts taken from the distribution curve were normalized for comparison. The peak shifts from the value of the intact particle height to the height of the cores. NANOSENSORS uniqprobe qp-BioAC AFM probes were used for the atomic force microscopy measurements.

Successful airborne transmission of coronaviruses through fluid microdroplets requires a virion structure that must withstand harsh natural conditions. * Because of the strict biosafety requirements… Read More »Monitoring SARS-CoV-2 Surrogate TGEV Individual Virions Structure Survival under Harsh Physicochemical Environments

Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys

Figure 5 from Morgan R. Jones et al. Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys: Tribofilm formation as a function of number of cycles as determined from the nanoscale experiments. (a) Intermittent-contact mode topography images (3 µm × 3 µm area) of the contact region at a contact pressure of 1.2 GPa after 0 cycles, 500 cycles, 1000 cycles, 2000 cycles, 3000 cycles, and 4000 cycles. (b) Tribofilm volume as a function of cycles for contact pressures up to 3.1 GPa. For all P, tribofilm volume increased asymptotically to a steady-state value at large numbers of cycles. NANOSENSORS Diamond Coated PointProbe Plus AFM probes DT-CONTR were used for the nanoscale tribology with atomic force microscopy.

Although catalysis is a popular explanation for tribopolymer generation, the interplay of catalysis, mechanochemistry, and electrostatic interactions remain incompletely understood. There is consensus, however, that… Read More »Stress- and Time-Dependent Formation of Self-Lubricating In Situ Carbon (SLIC) Films on Catalytically-Active Noble Alloys

Novel characteristics of soluble fibrin: hypercoagulability and acceleration of blood sedimentation rate mediated by its generation of erythrocyte-linked fibers

Figure 5 from D. Galanakis et al. “Novel characteristics of soluble fibrin: hypercoagulability and acceleration of blood sedimentation rate mediated by its generation of erythrocyte-linked fibers”: AFM images. Horizontal bars denote 100 nm and 50 nm in panels a and b, respectively. a FR fg adsorbed on a TOMA surface showing a large, upper arrow, and a smaller multimeric cluster, lower arrow, showing the marked variation in the cluster size. The smaller cluster also shows regular surface undulations indicating its multimeric composition. b FR fg adsorbed on modified graphite (MG) surface, showing a field of solitary trinocular monomers and two clusters. Inset: a 4 × magnification from a different area of the same field showing a monomer, right arrow, and a multimeric cluster, left arrow NANOSENSORS SuperSharpSilicon SSS-SEIHR AFM probes were used.

Soluble fibrin (SF) in blood consists of monomers lacking both fibrinopeptides A with a minor population in multimeric clusters. It is a substantial component of… Read More »Novel characteristics of soluble fibrin: hypercoagulability and acceleration of blood sedimentation rate mediated by its generation of erythrocyte-linked fibers

Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures

Fig. 4 from : Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures by Takuya Isono et al. Thin-film morphologies of Glc3-b-Sol and Glc4-b-Sol. AFM height images (a, b) and corresponding cross-sectional profiles (c, d) indicating the formation of 6–8-nm-thick horizontal lamellae in Glc3-b-Sol (a, c) and Glc4-b-Sol thin films (b, d). Thin-film samples were prepared by spin-coating the BCO solution onto the hydrophilic surface of a silicon substrate followed by thermal annealing at 85 °C for 1 h. NANOSENSORS PointProbe Plus PPP-NCHR standard silicon tapping mode AFM probes and NANOSENSORS SuperSharpSilicon high resolution silicon AFM probes were used

Discrete block co-oligomers (BCOs) can form highly ordered ultrasmall nanostructures which can be used for lithographic templates. These nanotemplates are promising for the low-cost, large-scale,… Read More »Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures
