Recent experimental advances have revealed that the mean free path (mfp) of phonons contributing significantly to thermal transport in crystalline semiconductors can be several microns long. Almost all of these experiments are based on bulk and thin film materials and use techniques that are not directly applicable to…
The structural organization of compounds in a confined space of nanometer-scale cavities is of fundamental importance for understanding the basic principles for atomic structure design at the nanolevel. Here, we explore size-dependent structure relations between one-dimensional PbTe nanocrystals and carbon nanotube co…
Abstract One challenge in the development of molecular photoswitches for solar energy storage is to increase the energy of the isomer formed upon irradiation. This work focuses on how to affect the relative stabilities of the isomers of the dihydroazulene/ vinylheptafulvene (DHA/VHF) couple by combining the light‐indu…
A new subgroup of bis(pyrazolyl)methane ligands has been developed through the synthesis of the first N , N , N , N ‐tetradentate bis(pyrazolyl)methane compounds, namely, bis(pyrazolyl)bipyridinylmethane [HC(Pz) 2 Bipy, L1 ] and bis(3,5‐methylpyrazolyl)bipyridinylmethane [HC(3,5‐MePz) 2 Bipy, L2 ]. From these ligands,…
] core are reported. 1 exhibits uni-axial anisotropy for which a slow magnetic relaxation is observed under 1.4 kOe dc field. It is the first example of an 8-coordinate Fe(ii) complex exhibiting field-induced single-molecule magnet (SMM) behaviour.
Susceptibility to intergranular corrosion (IGC) of 13 wt% Cr martensitic stainless steel, with different tempering treatments was studied by potentiodynamic and potentiostatic polarizations and a modified double loop electrochemical potentiokinetic reactivation (DL-EPR) tests in sulfuric acid solution. Further, the el…
The polar corundum structure type offers a route to new room temperature multiferroic materials, as the partial LiNbO 3 -type cation ordering that breaks inversion symmetry may be combined with long-range magnetic ordering of high spin d 5 cations above room temperature in the A FeO 3 system. We report the synthesis o…
Draft is unwanted local convective cooling. The draft risk model of Fanger et al. (Energy and Buildings 12, 21-39, 1988) estimates the percentage of people dissatisfied with air movement due to overcooling at the neck. There is no model for predicting draft at ankles, which is more relevant to stratified air distribut…
A facile one‐step hydrothermal strategy has been developed to prepare 3D porous Co 3 O 4 /graphene aerogel (Co 3 O 4 /GA). Due to the combination of a highly interconnected 3D network of GA and porous Co 3 O 4 nanospheres, the resulting Co 3 O 4 /GA electrode exhibits exceptional electrical conductivity and pseudocapa…
High thermal conductivity was obtained for nanofluid-based EG containing Cu nanoparticle-decorated Gr–MWCNT hybrid material synthesized by chemical reduction.
Fabrication of a multilayered quantum dot-light-emitting diode (QLED) with an inverted architecture cannot be usually fully solution-processed mainly due to the significant destruction of the pre-existing quantum dot (QD) emitting layer (EML) occurring during the subsequent solution-deposition of the hole transport la…
PHSCN peptide (licensed as ATN-161) is an effective α 5 β 1 integrin inhibitor that has advanced to phase II clinical trials to treat solid tumors. Here we developed ATN-161 functionalized self-cross-linkable and intracellularly de-cross-linkable polymersomes (ATN/SCID-Ps) for highly efficient and targeted delivery of…
Characterization of the three-dimensional (3D) structure in directed self-assembly (DSA) of block copolymers is crucial for understanding the complex relationships between the guiding template and the resulting polymer structure so DSA could be successfully implemented for advanced lithography applications. Here, we c…

O, ethanol, or a 0.008 m aqueous diethylenetriaminepentaacetic acid (DTPA) solution]. This is a simple approach for the fabrication of carbon dots with tunable photoluminescence (PL) that differs from other preparation methods, as no post-passivation step is required. The unfocused beam of the second harmonic (wavelen…
Mechanistic modeling facilitates rational crystallization engineering and design space screening. For an accurate model, the dominant growth mechanism operating on each face must be determined, which is highly dependent on supersaturation. Considering the case of centrosymmetric growth units, we developed and connecte…
Antifouling manganese oxide (Mn 3 O 4 ) nanoparticles (NPs) were synthesized by solvothermal decomposition of tris(2,4-pentanedionato) manganese(III) in the presence of trisodium citrate, followed by surface modification with polyethylene glycol and l -cysteine. The as-prepared nanoparticles have a uniform size distri…
Abstract Ag 2 O cubes, truncated octahedra, rhombic dodecahedra, and rhombicuboctahedra were synthesized in aqueous solution. Two tungsten probes were brought into contact with a single particle for electrical conductivity measurements. Strongly facet‐dependent electrical conductivity behaviors have been observed. The…
Inhibition of frost formation is important for increasing efficiency of refrigeration systems and heat exchangers, as well as for preventing the rapid icing over of water-repellant coatings that are designed to prevent accumulation of rime and glaze. From a thermodynamic point of view, this task can be achieved by eit…
High Resolution Image Download MS PowerPoint Slide We report an approach to linearly upscale hot-injection syntheses of colloidal nanocrystals by applying mild underpressure to the flask reactor prior to the injection such that rapid addition of large volumes of the precursor is facilitated. We apply this underpressur…
