description: We have investigated the vibrational density of states (VDOS) of a thin Cu nanowire with $<100>$ axial orientation and considered the effect of axial strain. The VDOS are calculated using a real space Green's function approach with the force constant matrices extracted from interaction potential based on the embedded atom method. Results for the vibrational density of states of a strain-free nanowire show quite distinctive characteristics compared to that of a bulk atom, the most striking feature of which is the existence of high frequency modes above the top of the bulk spectrum. We further predict that the low frequency characteristics of the VDOS reveal the quasi-1 dimensional (Q1D) behavior only when the wire is extremely thin. Through decomposition of VDOS into local atoms we also exhibit that while the anomalous increase in low frequency density of states is mainly due to the corner atoms, the enhancement in high frequency modes is primarily moderated by core atoms. We, additionally, find that while the high frequency band above the top of the bulk phonon shifts to higher frequencies, the characteristics at low frequencies remains almost the same upon stretching the nanowire along the axial direction.

description: Generically, massive gravity gives a non-unique gravitational field around a star. For a special family of massive gravity theories, we show that the stellar gravitational field is unique and observationally acceptable, that is close to Einsteinian. The black hole solutions in this family of theories are also studied and shown to be peculiar. Black holes have a near-horizon throat and the curvature diverging at the horizon. We show that there exists a sub-family of these massive gravity theories with non-singular at horizon black holes.

description: We examine the impact of a solid sphere into a fine-grained granular bed. Using high-speed X-ray radiography we track both the motion of the sphere and local changes in the bed packing fraction. Varying the initial packing density as well as the ambient gas pressure, we find a complete reversal in the effect of interstitial gas on the impact response of the bed: The dynamic coupling between gas and grains allows for easier penetration in initially loose beds but impedes penetration in more densely packed beds. High-speed imaging of the local packing density shows that these seemingly incongruous effects have a common origin in the resistance to bed packing changes caused by interstitial air.

description: The SPICA coronagraph instrument (SCI) provides high-contrast imaging and moderate resolution (R < 200) spectroscopy at the wavelength range from 3.5 to 27 μm. Based on the planet evolutional model calculated by Burrows et al. (2003), SCI will search for gas giant planets down to one Jupiter mass around nearby young (1 Gyr) stars and two Jupiter masses around nearby old (5 Gyr) stars. SCI also allows to characterizing those planets of less than 1 Gyr by spectroscopic observations to reveal the nature of planetary formation and evolution. Focusing on the high sensitivity and high contrast at wavelengths longer than 10 μm, we show that SCI also allows us to directly image icy giant planets like Uranus and Neptune as well as gas giant planets around nearby early-type stars. In this paper, we compare the capabilities of SCI and the JWST coronagraphs and also discuss a new approach to answering questions concerning the formation and evolution of planetary systems through planet detection with SCI.

CFD simulation of two- and three-phase flow in FCC reactors

Publisher: name: University of British Columbia
Year: 2015

description: Liquid distribution and evaporation in Fluid Catalytic Cracking (FCC) reactors are investigated numerically. The well-documented inaccuracy of conventional two-fluid modeling of hydrodynamics in fluidized beds of Geldart Group A particles is revisited. A new force-balance (FB) sub-grid-scale model, introduced and applied to the conventional Wen-Yu drag correlation, analyzes the balance of van der Waals, drag, gravity and buoyancy forces. It predicts formation of agglomerates inside the bed, updating the drag calculations by applying a correction factor to the conventional drag models. Good predictions are obtained of fluidization regimes and bed expansion, and there is promising agreement with experimental time-average radial voidage profiles reported by Dubrawski et al. (2013). Good quantitative agreement between discrete element models (DEM) and two-fluid predictions of minimum bubbling velocity is also observed when the model is used to predict minimum bubbling velocity, in contrast to the predictions from a non-cohesive, Wen-Yu model. Liquid injection experiments on a lab-scale fluidized bed were conducted, at the Institute of Chemical and Fuels from Alternative Sources (ICFAR) in London, Ontario to study the distribution, as well as the penetration, of liquid into catalyst pores. The results shed light on complexities involved in the injection zone to understand the effect of superficial gas velocity on evaporation and imbibition of liquid into particle pores. A methodology is developed to couple and incorporate existing liquid imbibition (into particle pores) models with evaporation models in the CFD code. The results are compared to another set of lab-scale experiments conducted at the British Columbia Research Institute (BCRI) facilities in Burnaby, BC. Simulation results demonstrate that CFD models can capture correct qualitative behavior of liquid injection and evaporation inside the bed. However, quantitative deviations revealed the likely effect of hydrodynamic properties on drying from both the liquid film around the particles and inside the pores. The deviations also imply that the assumption of convection- or diffusion-dominant drying might be unsuitable, and the two should be combined. Based on experimental results, a methodology is proposed to include the effect of hydrodynamic properties such as superficial gas velocity and particle impact velocity on drying.

description: The efficiency of collecting photons from optically active defect centres in bulk diamond is greatly reduced by refraction and reflection at the diamond-air interface. We report on the fabrication and measurement of a geometrical solution to the problem; integrated solid immersion lenses (SILs) etched directly into the surface of diamond. An increase of a factor of 10 was observed in the saturated count-rate from a single negatively charged nitrogen-vacancy (NV-) within a 5um diameter SIL compared with NV-s under a planar surface in the same crystal. A factor of 3 reduction in background emission was also observed due to the reduced excitation volume with a SIL present. Such a system is potentially scalable and easily adaptable to other defect centres in bulk diamond.

Origami engineering : advanced converting for novel paper products

Publisher: name: University of British Columbia

description: The recent work has focused to develop a fully automated prototype in order to make products in large quantities. A unique and novel methodology has been developed to create self-folding paper products. This platform technology enables us to create sophisticated complex 3D paper structure from ordinary 2D paper sheet. The self-folding material is composed of pre-cut and creased paper and heat shrinking thermoplastic polymer. A computational drawing tool is first used to design folds for particular 3D shape then a computer numerical controller cutter with knife at variable pressure is employed to cut paper and the thermoplastic polymer. The cut paper and thermoplastic polymer can be attached together by a large number of polymeric materials and several means of attaching polymer-paper have been explored. The effect of various polymer-paper attachments including chemical adhesion, stitching and welding was studied. Heat welding procedure was quite successful and it showed to be promising technique to make a strong polymer-paper bond. An experimental device was made and a series of experiments were conducted to reveal the significant factors, their effective range, and their impact on the paper-polymer bond strength. The effect of pressure, temperature, welding attachment area and, thickness of paper on the paper-polymer bond strength were determined and a database of strength attachments with an effective factors variation was collected. First, our in-house developed servo-robot for cutting was assisted with automatic welding system and then a large flatbed cutter has been used and functionally changed to perform cutting, creasing and adhering paper and plastic in one step. The effect of significant factors such as attachment distance to fold line, heating temperature and paper thickness on the folding angle has been studied and discussed in chapter 4. Several examples of folded decorative and industrial products have been developed using this technique and introduced in chapter 5.

description: We report the detection of CO(1-0) emission in the strongly lensed high-redshift quasars IRAS F10214+4724 (z=2.286), the Cloverleaf (z=2.558), RX J0911+0551 (z=2.796), SMM J04135+10277 (z=2.846), and MG 0751+2716 (z=3.200), using the Expanded Very Large Array and the Green Bank Telescope. We report lensing-corrected CO(1-0) line luminosities of L'(CO) = 0.34-18.4 x 10^10 K km/s pc^2 and total molecular gas masses of M(H2) = 0.27-14.7 x 10^10 Msun for the sources in our sample. Based on CO line ratios relative to previously reported observations in J>=3 rotational transitions and line excitation modeling, we find that the CO(1-0) line strengths in our targets are consistent with single, highly-excited gas components with constant brightness temperature up to mid-J levels. We thus do not find any evidence for luminous extended, low excitation, low surface brightness molecular gas components. These properties are comparable to those found in z>4 quasars with existing CO(1-0) observations. These findings stand in contrast to recent CO(1-0) observations of z~2-4 submillimeter galaxies (SMGs), which have lower CO excitation and show evidence for multiple excitation components, including some low-excitation gas. These findings are consistent with the picture that gas-rich quasars and SMGs represent different stages in the early evolution of massive galaxies.

description: Based on our analytical results [http://arxiv.org/abs/1006.3670], we predict that undoped nanoparticles (size <10-100nm) of incipient ferroelectrics without any magnetic ions can become ferromagnetic even at room temperatures due to the inherent presence of a new type of magnetic defects with spin S=1, namely oxygen vacancies, where the magnetic triplet state is the ground state in the vicinity of the surface (magnetic shell), while the nonmagnetic singlet is the ground state in the bulk material (nonmagnetic core). Consideration of randomly distributed magnetic spins (S=1) had shown that magnetic properties of incipient ferroelectric nanoparticles are strongly size and temperature dependent due to the size and temperature dependence of their dielectric permittivity and the effective Bohr radius proportional to permittivity. The phase diagrams in coordinates temperature - particle radius are considered. In particular, for particle radii less that the critical radius ferromagnetic long-range order appears in a shell region of thickness 5 - 50 nm once the concentration of magnetic defects exceeds the magnetic percolation threshold. The critical radius is calculated in the mean field theory from the condition of the magnetic defects exchange energy equality to thermal energy. For particle radii higher than critical value only the paramagnetic phase is possible. The conditions of the super-paramagnetic state appearance in the assembly of nanoparticles with narrow distribution function of their sizes are discussed also.

description: To describe clinical effects and outcomes of hymenopteran stings and to explore the non-laboratory factors associated with adverse clinical outcomes, a composite outcome including death, respiratory failure requiring intubation, acute kidney injury (AKI) requiring dialysis and hypotension requiring vasopressor use. A retrospective cross-sectional study was performed at the Ramathibodi Poison Center, a poison centre of a tertiary care hospital in Thailand. All cases of hymenopteran sting consultations from January 2015 to June 2019 were consecutively enrolled, and charts were reviewed. Demographics, initial clinical characteristics and outcomes were collected. Factors associated with adverse clinical outcome were explored. One hundred and fourteen hymenopteran stings cases (wasp 48%, bee 33%, hornet 14% and carpenter bee 8.8%) were included (median age, 36.5 years (interquartile range 9–55); male 63%). The prevalence of adverse clinical outcomes was 12.3% (95%CI 6.88–12.8). At initial presentation, 100% of cases had local skin reactions, 11.4% were clinical anaphylaxis, and 8% had red urine. Adverse clinical outcomes included death (n = 10), respiratory failure requiring intubation (n = 9), AKI requiring dialysis (n = 6) and hypotension requiring vasopressor use (n = 2). None of the patients with carpenter bee or hornet stings developed adverse clinical outcomes. In univariable analysis, urticaria, wheezing, red urine, wasp sting and sting number > 10 were significantly associated with adverse clinical outcomes. In multivariable analysis, red urine (adjusted OR 11.1 (95% CI 1.57–216)), wheezing (adjusted OR 16.7 (95% CI 1.43–402)) and a number of stings > 10 (adjusted OR 21.5 (95% CI2.13-2557)) were significant. Adverse clinical outcomes in hymenopteran stings were not uncommon among cases inquiring to a national Thai poison centre. At initial presentation, red urine, wheezing and a number stings >10 were significantly associated with adverse clinical outcomes. Larger epidemiologic studies are required to confirm these associations.

description: Although developing a cultural identity is a core task for adolescents from immigrant families and the school is a highly important context in adolescence, to date, few studies have examined whether adolescents with particular cultural identities cluster in certain school contexts. Using data from a representative German sample including 7702 secondary school students of immigrant background from 1643 classrooms, we examined how the attended school track and four aspects of ethnic classroom composition relate to adolescents' cultural identity (i.e., their ethnic identity and mainstream identity). Two-level structural equation models indicated that students' ethnic identity was not systematically associated with the attended school track and the ethnic composition of the classroom. However, attending the academic school track, a classroom with a low proportion of classmates with immigrant background and frequently using German with classmates related positively to mainstream identity. Ethnic diversity and proportion of co-ethnics in class did not relate to mainstream identification. Our findings suggest that the ethnic identity of adolescents with an immigrant background in Germany is largely independent from the different socialisation contexts related to school tracks and the ethnic classroom composition. Yet, students' with a strong mainstream identity cluster in certain school contexts.

description: The solar surface magnetic field is connected with and even controls most of the solar activity phenomena. Zeeman effect diagnostics allow for measuring only a small fraction of the fractal-like structured magnetic field. The remaining hidden magnetic fields can only be accessed with the Hanle effect. Molecular lines are very convenient for applying the Hanle effect diagnostics thanks to the broad range of magnetic sensitivities in a narrow spectral region. With the UV version of the Zurich Imaging Polarimeter ZIMPOL II installed at the 45 cm telescope of the Istituto Ricerche Solari Locarno (IRSOL), we simultaneously observed intensity and linear polarization center-to-limb variations in two spectral regions containing the (0,0) and (1,1) bandheads of the CN B 2 Σ - X 2 Σ system. Here we present an analysis of these observations. We have implemented coherent scattering in molecular lines into a NLTE radiative transfer code. A two-step approach was used. First, we separately solved the statistical equilibrium equations and compute opacities and intensity while neglecting polariza- tion. Then we used these quantities as input for calculating scattering polarization and the Hanle effect. We have found that it is impossible to fit the intensity and polarization simultaneously at different limb angles in the frame- work of standard 1D modeling. The atmosphere models that provide correct intensity center-to-limb variations fail to fit linear polar- ization center-to-limb variations due to lacking radiation field anisotropy. We had to increase the anisotropy by means of a specially introduced free parameter. This allows us to successfully interpret our observations. We discuss possible reasons for underestimating the anisotropy in the 1D modeling.

description: Results from the measurement of dynamical $K/π$ and $p/π$ ratio fluctuations are presented. Dynamical fluctuations in global conserved quantities such as baryon number, strangeness, or charge may be observed near a QCD critical point. The first measurement of results of $K/π$ and $p/π$ fluctuations from Cu+Cu collisions at an energy $\sqrt{s_{NN}}$ = 22.4 GeV are shown. This energy range is close to the top SPS energy and has garnered additional interest due to the proposed QCD critical point search at RHIC. The new Cu+Cu data is compared to previous results from Au+Au collisions at the energies $\sqrt{s_{NN}}$ = 19.6, 62.4, 130, and 200 GeV, and to measurements from the NA49 experiment. The dynamical $K/π$ fluctuation results from Cu+Cu at $\sqrt{s_{NN}}$ = 22.4 GeV are in good agreement with previous measurements from the STAR and NA49 experiments near that energy. Results are compared to theoretical predictions from several models including the HIJING and UrQMD models.

The models indicate new features of the instability: the influence of quantum capillary waves and the separation of droplets, which are qualitatively different from the classical case. We perform numerical simulations of the instability in a trapped Bose-Einstein condensate using the Gross-Pitaevskii equation and compare the simulation results to the model predictions.

We confirm the magnetic inclination angle dependent transmission of incident acoustic waves into upward propagating waves, and derive (1) proof that helioseismic travel times receive direction dependent contributions from such waves and hence cause errors in conventional flow inferences, (2) evidences for acoustic wave sources beneath the umbral photosphere, and (3) significant differences in travel times measured from the chosen magnetically sensitive and insensitive spectral lines.

description: This work conducts a life-cycle assessment (LCA) of ethanol production from sugarcane bagasse in the Indian context. A cradle-to-gate system boundary was considered, and a functional unit of 1 MJ of energy from ethanol was used. Eight pre-treatment technologies and four hydrolysis-fermentation technologies were considered, thereby comparing 32 process combinations. Process data were collected from various published studies, government reports and also personal communication, and were used to perform LCA. The ReCiPe and TRACI models were used to perform the impact assessment using OpenLCA 1.6.1. The results show that the dilute acid pre-treatment (DA) with simultaneous saccharification and fermentation (SSCF) processing route had lower impacts in most categories. The global warming potential for this combination was 0.132 kg CO2 eq. per MJ, with 85% of the contribution due to steam generation. The impact can be reduced to 0.019 kg CO2 eq. per MJ by using a natural gas for steam generation. Ammonia fiber explosion (AFEX) pre-treatment had the highest impact in many categories, primarily due to ammonia production, implying the importance of ammonia recycling. DA had a lower impact due to higher yields and lower biomass requirements. The water footprint ranged between 232 and 672 L/L of ethanol and was mostly dominated by agricultural water.

description: A large variety of explosions result in mildly or ultra relativistic shock breakouts. Here we calculate the luminosity and spectrum that these breakouts produce. In order to do so we improve an analytic description of relativistic radiation mediated shocks and follow the system from the breakout itself, through the planar phase and into the spherical phase. We limit our calculation to cases where the post breakout acceleration of the gas ends during the planar phase. (i.e., the final gas Lorentz factor

description: In the present work, we develop a systematic examination of the existence, stability and dynamical properties of a discrete breather at the interface between a diatomic and a monoatomic granular chain. We remarkably find that such an "interface breather" is more robust than its bulk diatomic counterpart throughout the gap of the linear spectrum. The latter linear spectral gap needs to exist for the breather state to arise and the relevant spectral conditions are discussed. We illustrate the minimal excitation conditions under which such an interface breather can be "nucleated" and analyze its apparently weak interaction with regular highly nonlinear solitary waveforms.

description: A general kind of Brownian vortexes are demonstrated by applying an external nonconservative force field to a colloidal particle bound by a conservative optical trapping force at a liquid-air interface. As the liquid medium is translated at a constant velocity with the bead trapped at the interface, the drag force near the surface provide enough rotational component to bias the particle's thermal fluctuations in a circulatory motion. The interplay between the thermal fluctuations and the advection of the bead in constituting the vortex motions is studied, inferring that the angular velocity of the circulatory motion offers a comparative measure of the interface fluctuations.

description: Numerous studies already identified that the fatigue strength of 316 L parts processed by laser beam melting (LBM) is distinctly affected by the surface integrity. Among others, surface defects as well as residual stresses are of crucial importance. Despite new findings in the field of surface engineering of laser beam melting (LBM) parts, the low cycle fatigue strength of thermally sprayed additively manufactured substrates has not been in the focus of research to date. This study aims at evaluating the effect of different pre-treatments onto 316 L substrates processed by laser beam melting (LBM) prior to the deposition of a high velocity oxy-fuel (HVOF) sprayed tungsten carbide-cobalt coating and their effect on the low cycle fatigue strength. Therefore, 316 L substrates were examined in their as-built state as well as after grit blasting with regards to the surface roughness, strain hardening effects, and residual stresses. To differentiate between topographical effects and residual stress related phenomena, stress-relieved 316 L substrates served as reference throughout the investigations. The tungsten carbide-cobalt coated and differently pre-treated 316 L substrates were mechanically tested under quasi-static and dynamic load conditions. Besides the low cycle fatigue strength, the fracture toughness as well as the fracture mechanism were identified based on fracture surface analysis.

description: Chemical compositions of plant essential oils can be affected by many environmental and biological factors. Understanding the role of individual constituents and their interactions to overall insecticidal bioactivity is prerequisite to the use of essential oils as an alternative to conventional insecticides. In the present study, the chemical compositions of Rosmarinus officinalis (rosemary), Thymus vulgaris (thyme) and Cymbopogon citratus (lemongrass) essential oils were analyzed by gas chromatography-mass spectrophotometry (GC-MS), and relationships between chemical composition and toxicity of the constituents, and synergistic interactions of the major constituents of the oils were evaluated against third instar larvae and an ovarian cell line of the cabbage looper, Trichoplusia ni, via different application methods. To explore underlying mechanisms of synergy, penetration through the insect cuticle and inhibitory activities on three detoxifying enzyme systems were investigated. The most abundant constituents of rosemary, thyme and lemongrass oils were 1,8-cineole, thymol and citral, respectively, and their overall contributions to in vivo and in vitro toxicity varied according to the application methods, as did their designation as major active principles. A weak correlation between insecticidal activity and cytotoxicity was observed, indicating limitation of insect cell cultures as a screening tool for novel insecticides. Several synergistic interactions were found among the major constituents of each oil, including 1,8-cineole+camphor, thymol+p-cymene and citral+limonene. Analysis by GC-MS showed a significant penetration-enhancing effect of topically applied camphor by 1,8-cineole in their synergistic binary mixture. 1,8-Cineole was more toxic than camphor when applied topically to larvae, but a bioassay via injection revealed greater toxicity of camphor than 1,8-cineole. A bioassay combining injection and topical application confirmed the increased penetration of both compounds when mixed, showing the same bioactivity with higher amounts applied individually. A similar pattern of enhanced penetration of insecticides through the cuticle of T. ni in other synergistic combinations was observed as well. Lowered surface tension and increased solubility along with the interaction between essential oil constituents and the lipid layer of the insect’s cuticle may explain their enhanced penetration. Although some mild enzyme inhibitory activities were observed in essential oil-treated larvae, no correlation was observed between detoxicative metabolism and synergistic toxicity.

description: The combination of an alkoxy and an amino function combined in one silane is rarely found due to the difficult synthesis and isolation.[1] However, this combination offers unique opportunities to investigate the influence of steric requirements or the size of a metal on the structure or reactivity of alkoxysilylamides towards electrophiles by varying the metallating reagent (n-butyllithium or di-n-butylmagnesium) or the organo group on the amino function. For this purpose, we synthesized two alkoxyaminosilanes with acidic NH units that can be metalated. On the one hand, the tert-butylamino-substituted (tert-butylamino)-methoxydiphenylsilane (1) and on the other hand the isopropylamino-substituted methoxydiphenyl(isopropylamino)silane (2). The resulting structures showed an interesting interrelation between the Si–O or Si–N bond lengths and the strength of the coordinative bond to the corresponding metal cation (lithium or magnesium).

description: The atomic third-order open-shell many-body perturbation theory is developed. Special attention is paid to the generation and algebraic analysis of terms of the wave operator and the effective Hamiltonian as well. Making use of occupation-number representation and intermediate normalization, the third-order deviations are worked out by employing a computational software program that embodies the generalized Bloch equation. We prove that in the most general case, the terms of effective interaction operator on the proposed complete model space are generated by not more than eight types of the $n$-body ($n\geq2$) parts of the wave operator. To compose the effective Hamiltonian matrix elements handily, the operators are written in irreducible tensor form. We present the reduction scheme in a versatile disposition form, thus it is suited for the coupled-cluster approach.
Innovative polymeric iron chelators with iron binding affinity and biocompatibility for the treatment of transfusional iron overload.

description: Desferrioxamine (Desferal®, DFO), deferiprone (Ferriprox®, L1) and desferasirox (Exjade®, ICL-670) are clinically approved iron chelators used to treat transfusion associated iron overload, a common condition in patients with severe hemoglobin disorders like β-thalassemia, sickle-cell disease and the myelodysplastic syndromes. The poor pharmacokinetics and inefficacy of iron chelators necessitate administration of almost maximum tolerated doses to achieve adequate iron removal. This causes toxicity ranging from neurological dysfunction in DFO users, agranulocytosis and neutropenia in L1 users, and severe kidney toxicity in ICL-670 treated patients. This also hinders the use of iron chelators during gestation. Thus, developing iron chelators with improved long-term efficacy and reduced toxicity is essential. All currently approved iron chelators are of low molecular weight (MW) (< 600 Da) and the objectives reported for the “ideal” chelator of low MW is yet to be realized in practice. However, the limited attempts towards developing higher MW, long circulating iron chelators has shown tremendous promise. This thesis assesses the role of a new polymer, hyperbranched polyglycerol (HPG) in improving the properties of iron chelators. High MW iron chelators were developed by conjugating DFO to HPG of various MWs, forming a library of HPG-DFO conjugates. Iron binding affinity of HPG-DFO was investigated using isothermal titration calorimetry, UV-visible spectroscopy and studying iron removal from ferritin. Biocompatibility and toxicity were investigated using coagulation assays in human blood and cell culture. Since iron chelator toxicity during development remains an under-explored area, the second goal of this thesis was to expand knowledge of chelator toxicity during development. The toxicity of FDA-approved and HPG-DFO in developing embryos was investigated using zebrafish. Studies indicate that HPG-DFOs are biocompatible, efficient chelators, capable of binding ferritin iron and preventing harmful redox reactions. Moreover, combining a low MW iron chelator with HPG-DFO enhances chelation. In vivo chemical screening indicated that while low MW chelators L1 and ICL-670 may interact with zebrafish embryos and cause toxicity, DFO and HPG-DFO did not have this effect. Results indicate that HPG-DFO is a new class of efficient, biocompatible iron chelator, potentially useful for development into clinical agents for the prevention of transfusion associated iron overload.

description: Biomolecular condensates consisting of proteins and nucleic acids can serve critical biological functions, so that some condensates are referred as membraneless organelles. They can also be disease-causing, if their assembly is misregulated. A major physicochemical basis of the formation of biomolecular condensates is liquid–liquid phase separation (LLPS). In general, LLPS depends on environmental variables, such as temperature and hydrostatic pressure. The effects of pressure on the LLPS of a binary SynGAP/PSD-95 protein system mimicking postsynaptic densities, which are protein assemblies underneath the plasma membrane of excitatory synapses, were investigated. Quite unexpectedly, the model system LLPS is much more sensitive to pressure than the folded states of typical globular proteins. Phase-separated droplets of SynGAP/PSD-95 were found to dissolve into a homogeneous solution already at ten-to-hundred bar levels. The pressure sensitivity of SynGAP/PSD-95 is seen here as a consequence of both pressure-dependent multivalent interaction strength and void volume effects. Considering that organisms in the deep sea are under pressures up to about 1 kbar, this implies that deep-sea organisms have to devise means to counteract this high pressure sensitivity of biomolecular condensates to avoid harm. Intriguingly, these findings may shed light on the biophysical underpinning of pressure-related neurological disorders in terrestrial vertebrates.
