Near-the-surface instabilities with a cusplike morphology were observed in ultrathin photo-cross-linked poly(N-isopropylacrylamide) coatings upon swelling in water. The characteristic wavelength of the instability was approximately 25 times the dry thickness and scaled linearly with coating thickness between 30 and 12…
Protein phosphorylation represents one of the most extensively studied post-translational modifications, primarily due to the emergence of sensitive methods enabling the detection of this modification both in vitro and in vivo. The availability of enrichment methods combined with sensitive mass spectrometry instrument…
IMPORTANCE OF THE FIELD: siRNAs may serve as novel nanomedicines for sequence-specific gene silencing in the clinic. However, delivering siRNA to targeted tissue or cells remains a challenge. An appropriate delivery nanosystem such as cationic polymers or liposomes is required for effective gene silencing with siRNA i…
A winning combination: Resveratrol derivatives incorporating a chroman moiety of vitamin E were constructed, resulting in the remarkable enhancement in tris(2,4,6-trichloro-3,5-dinitrophenyl)methyl radical (HNTTM.)-scavenging activity as compared with the parent molecules (see scheme). Reaction kinetic analysis, oxida…
Mesenchymal stromal/stem cells (MSCs) were originally isolated from bone marrow (BM), but are now known to be present in all fetal and adult tissues. These multipotent cells can be differentiated into at least three downstream mesenchymal lineages that include bone, cartilage, and fat. However, under some experimental…
A new unsymmetrical AB* inimer, p -(2-bromoisobutyloylmethyl)styrene (BiBMS), was applied to the atom transfer radical polymerization (ATRP) to prepare a family of polymers with the topologies ranging from linear to branched. The catalyst system was Cu/CuBr 2 coupled with 2,2′-bipyridine (Bipy) or N,N -bis(2-pyridylme…
Despite significant advances in management of severe wounds such as burns and chronic ulcers, autologous split-thickness skin grafts are still the gold standard of care. The main problems with this approach include pain and discomfort associated with harvesting autologous tissue, limited availability of donor sites, a…
A pilled fabric image consists of sub‐images of different frequency components, and the fabric texture and the pilling information are in different frequency bands. Interference from fabric background texture affects the accuracy of computer‐aided pilling ratings. A new approach for pilling evaluation based on the mul…
Direct delivery: Multifunctionalized magnetic nanoparticles, which are highly stable and positively charged, induce strong interactions with cells and nuclei, thus confining bleomycin (BLM) close to its DNA target (see picture; PEG=polyethylene glycol). Grafted BLM can induce significant damage in DNA and cancerous ce…
Current-induced magnetization switching (CIMS) in CoFeB (pinned layer)/MgO/Fe 4 N (free layer) magnetic tunnel junctions (MTJs) was investigated at room temperature and an inverse CIMS phenomenon was clearly identified. From the current-field magnetic phase diagram, determined from the dependence of the switching fiel…
Porous titanosilicate beads with a diameter of 0.5-1.5 mm (TiSil-HPB-60) were synthesized from a preformed titanosilicate solution with a porous anion-exchange resin as template. The bead format of this material enables its straightforward separation from the reaction mixture in its application as a liquid-phase heter…
Hybrid scenario performance in ITER is studied with the CRONOS integrated modelling suite, using the GLF23 anomalous transport model for heat transport prediction. GLF23 predicted core confinement is optimized through tailoring the q-profile shape by a careful choice of current drive actuators, affecting the transport…
The parenteral route has many merits over the oral route, including greater predictability, reproducibility of absorption, and rapid drug action, but injectable phytomedicines are uncommon due to protein precipitating tannin and hemolytic saponin components. In this study, in an effort to develop a safe injectable ana…
The surface morphology and nanomechanical properties of poly(styrene- b -ethylene- co -butylene- b -styrene) (SEBS) having different compositions were investigated using nanomechanical mapping measurements based on atomic force microscopy. We obtained the deformation image, true surface morphology, high-resolution You…
Abstract Cu(0)‐mediated living radical polymerization was first extended to acrylonitrile (AN) to synthesize polyacrylonitrile with a high molecular weight and a low polydispersity index. This was achieved by using Cu(0)/hexamethylated tris(2‐aminoethyl)amine (Me6‐TREN) as the catalyst, 2‐bromopropionitrile as the ini…
An otherwise dark magnetic dipole resonance in a split-ring resonator can be excited electrically with a Fano-type profile once the symmetric environment for this resonator is broken with respect to the polarized electric-field direction of incident waves. When this asymmetrically induced narrow resonance coincides wi…
As there are error judgments of float type in the traditional method based on image processing, it is hard to determine the woven fabric pattern from the recognition results. To solve this problem, fuzzy C‐means (FCM) algorithm was selected to classify the floats into two groups in the experiment, and BP neural networ…
A combined analysis of the electron localizability indicator (ELI; see isosurface ELI for TiBe2) and electron density, the characteristic structural motif of the Laves phases MN2 was shown to be mainly stabilized by charge transfer from M to N. In different groups of Laves phases, the bonding situation ranges from mul…
Abstract Oxygen transport across the cathode gas diffusion layer (GDL) in polymer electrolyte membrane (PEM) fuel cells was examined by varying the O2/N2 ratio and by varying the area of the GDL extending laterally from the gas flow channel under the bipolar plate (under the land). As the cathode is depleted of oxygen…
Nanometals are manufactured to particle sizes with diameters in the nanometer range and are included in a variety of consumer and health products. There is a lack of information regarding potential effects of these materials on aquatic organisms. Amphibians are regarded as environmental sentinels and demonstrate an ex…
