The great potential of nanoporous membranes for water filtration and chemical separation has been challenged by the trade-off between selectivity permeability. Here we report on polymer with an excellent balance permeability ions. Our are fabricated irradiating 2-μm-thick polyethylene terephthalate Lumirror® films GeV heavy ions followed ultraviolet exposure. These show a high transport rate K+ up to 14 mol h-1 m-2 alkali metal over >500. Combining experiments molecular dynamics simulations...
Novel transport phenomena through nanopores are expected to emerge as their diameters approach subnanometer scales. However, it has been challenging explore such a regime experimentally. Here, this study reports on polymer pores exhibiting unique selective ionic transport. 12 μm long, parallel oriented fabricated in polyethylene terephthalate (PET) films by irradiation with GeV heavy ions and subsequent 3 h exposure UV radiation. These show selectivity spanning more than 6 orders of...
Physicochemical properties of the cationic liposomes, including structure lipids, lipid-to-DNA ratio, liposome particle size, and inclusion helper were studied for their effect on level, site, duration time gene expression in vivo by intravenous administration. Using a cytomegalovirus (CMV)-driven system containing either luciferase or green fluorescence protein as reporter two lipids [N-(2,3-dioleoyloxy)propyl-N,N,N-trimethylammonium chloride (DOTMA) 1,2-dioleoyloxy-3-trimethylammonium...
Reverse electrodialysis is a promising method to harvest the osmotic energy stored between seawater and freshwater, but it has been long-standing challenge fabricate permselective membranes with power density surpassing industry benchmark of 5.0 W m
Patterning of body parts in multicellular organisms relies on the interpretation transcription factor (TF) concentrations by genetic networks. To determine extent which absolute TF concentration dictates gene expression and morphogenesis programs that ultimately lead to patterns Drosophila embryos, we manipulate maternally supplied patterning determinants measure readout at position various developmental markers. When increase overall amount maternal Bicoid (Bcd) fivefold, Bcd cells...
In the present paper, a new cyclodextrin/porphyrin supramolecular sensitizer for zinc ion has been proposed based on porphyrin dual fluorescence emission ratio. aqueous solution, meso-tetraphenylporphyrin shows weak fluorescence, while in presence of alkylated β-cyclodextrin, it exhibits significant enhancement by forming inclusion complex. Furthermore, formation complex causes remarkable increase metalation rate following changes at two different wavelengths. The tetraphenylporphyrin 656-nm...
The initial aggregation kinetics of hematite nanoparticles (NPs) that were conjugated with two model globular proteins—cytochrome c from bovine heart (Cyt) and serum albumin (BSA)—were investigated over a range monovalent (NaCl) divalent (CaCl2) electrolyte concentrations at pH 5.7 9. behavior Cyt-NP conjugates was similar to bare NPs, but the additional electrosteric repulsion increased critical coagulation concentration (CCC) values 69 mM 113 in NaCl 5.7. An unsaturated layer BSA, protein...
The electrokinetic effect to convert the mechanical energy from ambient has gained sustained research attention because it is free of moving parts and easy be miniaturized for microscale applications. practical application constrained by limited conversion performance. Herein, we report vertically oriented MXene membranes (VMMs) with ultrafast permeation as well high ion selectivity, in which several thousand higher than largely researched horizontally stacked (HMMs). VMMs can achieve a...
The interplay between dehydration and electrostatic interactions leads to a switch in ion selectivity nanochannels as the surface charge density increases.
A new zinc(II) porphyrin conjugate with an appended pyrene subunit has been synthesized and shown to exhibit significant analytical usefulness for fluorescence sensing toward imidazole derivatives. The molecular recognition was based on the bridging interaction of ring analyte center porphyrin, while transduction signal process excimer fluorescence. sensor constructed applied assay histidine in aqueous solution by immobilizing material a plasticized PVC membrane.

The sympathetic nervous system (SNS) regulates bone resorption through β-2 adrenergic receptor (Adrb2). In orthodontic tooth movement (OTM), mechanical force induces and alveolar remodeling. Compressive force-associated osteoclast differentiation are the rate-limiting steps of movement. However, whether can activate Adrb2 thus contribute to OTM remains unknown. this study, nickel-titanium springs were applied upper first molars rats Adrb1/2(-/-) mice confirm role SNS in OTM. results showed...
Periodontal ligament (PDL) is subjected to mechanical force during physiologic activities. PDL stem/progenitor cells are the main mesenchymal stem in PDL. However, how progenitors participate homeostasis upon and after largely unknown. In this study, force-triggered orthodontic tooth movement following relapse were used as models demonstrate response of their role remodeling force. Upon force, collagen on compression side significantly degraded, showing a broken disorganized pattern. After...
Abstract Searching for possible biochemical networks that perform a certain function is challenge in systems biology. For simple functions and small networks, this can be achieved through an exhaustive search of the network topology space. However, it difficult to scale approach up larger more complex functions. Here we tackle problem by training recurrent neural (RNN) desired function. By developing systematic perturbative method interrogate successfully trained RNNs, are able distill...

With the development of nano-fabrication and nanofluidics, nanoporous membranes have shown great potential in applications such as molecular separation, energy conversion, sensing. However, their performance has often been limited by trade-off between selectivity permeability lack scalability. The prospect overcoming these problems with polymer ion-track is promising. Focusing on membranes, this review provides a comprehensive overview fabrication methods, including traditional track-etching...
