Abstract Contact‐killing antimicrobial coatings are important for reducing medical device related nosocomial bacterial infections, yet they inadvertently suffer from rapid bacterial colonization. To lessen the extent of biofilm formation on such surfaces, it is hypothesized that coatings containing alternating regions…
The contemporary trend of cost-saving is the primary motive while studying the relative motion between the material surfaces. Therefore, exceptional surface characteristics are the most desirable features for any material. The rapid emerging surface modification phenomena like Friction Stir Processing (FSP) have prove…
Abstract The two‐photon excited process of surface‐enhanced hyper‐Raman scattering (SEHRS) provides advantages for studies of complex biological samples, yet suitable SEHRS nanoprobes and labels, as well as experimental conditions, must be established. Here, SEHRS spectra of the four reporter molecules (2‐naphthalenet…
Abstract Fabricating 2D organic crystalline semiconductors (2DOCSs) in a patterned structure is an essential prerequisite for application toward large‐scale and high‐throughput manufacturing integrated devices. However, the deposition of 2DOCS arrays with structural perfection and thickness control through suitable so…
Three-dimensional (3D) cardiac tissue reconstruction using tissue engineering technology is a rapidly growing area of regenerative medicine and drug screening development. However, there remains an urgent need for the development of a method capable of accurately measuring the contractile force of physiologically rele…
Abstract Boosting the efficiency and lifetime of all inorganic metal halide perovskite nanocrystals (PeNCs) based light‐emitting diodes (PeLEDs) will promote the application of PeNCs in displays and lighting. However, achieving high‐stability CsPbBr3 NCs is still a critical challenge. In this study, a physical adsorpt…
A novel method is developed in this paper to characterize the band diagram and band modal fields of gyromagnetic photonic crystals that support topological one-way edge states. The proposed method is based on an integral equation formulation that utilizes the broadband Green's function (BBGF). The BBGF is a hybrid rep…
Abstract Morphology evolution of conjugated organic molecular materials in the solid state has important implications for optoelectronic applications. Two aspects that have a large impact on materials self‐assembly in the film are the nature of the side‐chains and the processing conditions. Films of N‐annulated peryle…
The development of nanocomposites has swiftly changed the horizon of drug delivery systems in defining a new platform. Major understanding of the interaction of nanocomposites with cells and how the interaction influences intracellular uptake is an important aspect to study in order to ensure successful utilisation of…
This paper introduces the fabrication of a lemon battery enabled through Fused Deposition Modelling (FDM) with commercially available filaments in combination with electrodeposition. The battery consists of a printed polylactic acid (PLA) structure with two 3D-printed, conductive polymer composite electrodes with a la…
New functional initiators for the cationic ring-opening polymerization of 2-alkyl-2-oxazolines are described to introduce a thiol moiety at the α terminus. Both tosylate and nosylate initiators carrying a thioacetate group are obtained in multigram scale, from commercial reagents in two steps, including a phototrigger…
This work presents biocompatible flexible piezoelectric composite fabricated by self-assembly of amino acid glycine molecules inside natural chitosan polymer. Piezoelectric composite film consists of glycine spherulite structure embedded in chitosan matrix. The x-ray diffraction confirms the crystallization of stable…
A multi‐responsive Cd metal–organic framework {[Cd (ttpe)(H2O)(ip)]•4H2O•DMAC}n (1•4H2O•DMAC) was synthesized using hydrothermal method (ttpe = 1,1,2,2‐tetra(4‐(1H‐1,2,4‐triazol‐1‐yl)phenyl)ethylene, ip = isophthalate, DMAC = N,N‐dimethylacetamide), and characterized. 1 exhibits a 2D (4,4) network. The luminescent sen…
At high frequency, AC resistance of a printed circuit board (PCB) winding becomes important and accounts for a large proportion of planar transformer losses. The winding is then influenced by both skin and proximity phenomenon, which makes the current distribution uneven resulting in an increased resistance. The study…
Boiling heat transfer is known for high heat fluxes at relatively small temperature differences. However, over the decades, technological innovations have demanded further augmentation in heat fluxes associated with boiling. Among the various active and passive methods, use of ultrasonic waves in boiling liquid has em…
Power quality problems are becoming a major issue. Every utility company consumer desires to receive steady-state voltage, i.e. a sinusoidal waveform of constant frequency as generated at power stations, but the influence of disturbances in the shape of sags and swells, interruptions, transients and harmonic distortio…
Abstract Engineering large and functional tissue constructs with complex structures (e.g., external ear or nose) for reparation and reconstruction of tissue defects remains one of the major challenges in regenerative medicine, which demands abundant cell sources, advanced biofabrication schemes, and satisfactory integ…
2-Phenylquinoline ( PQ ) and four coumarin-based ligand isomers with ease of synthesis have been selected to construct the unsymmetric heteroleptic [Ir(C 1 ∧ N)(C 2 ∧ N)(acac)]-type complex phosphors for organic light-emitting diodes (OLEDs). Six unsymmetric heteroleptic Ir(III) complexes have been obtained by employi…
Abstract The fatigue life of cast steel G42CrMo4 in two different heat treatment conditions was investigated at room temperature (RT), 473 K and 773 K up to the range of very high cycle fatigue (VHCF), that is, 109 cycles. The fatigue life is determined by casting defects, the hardness of the steel matrix and by tempe…
Curved π-electronic molecules, dipyrrolylbenzodiazepines (dpbs), were synthesized via condensation of 1,3-dipyrrolyldiketones and phenylenediamines. Dpbs exhibited 1D hydrogen-bonding chains between pyrrole NH and diazepine N and the resulting packing structures in the solid state. The pyrrole and diazepine N sites co…
