Technology used for computer chip manufacturing is combined with soft lithography to produce small polymeric structures.
Abstract Alkaline water electrolysis at high current densities is plagued by gas bubble generation and trapping in stochastic porous electrodes (e.g., Ni foams), which causes a significant reduction the number of electrolyte accessible catalyst active sites. Here, 3D printed (3DPNi) with highly controlled, periodic structures are reported that suppress coalescence, jamming, and, hence, result rapid release. The 3DPNi decorated carbon‐doped NiO achieve density 1000 mA cm −2 1.0 m KOH hydrogen...
Maintaining fast charging capability at low temperatures represents a significant challenge for supercapacitors. The performance of conventional porous carbon electrodes often deteriorates quickly with the decrease temperature due to sluggish ion and charge transport. Here we fabricate 3D-printed multiscale aerogel (3D-MCA) via unique combination chemical methods direct ink writing technique. 3D-MCA has an open structure large surface area ∼1750 m2 g–1. At −70 °C, symmetric device achieves...
Aqueous rechargeable zinc–iodine batteries (ZIBs) are promising candidates for grid energy storage because they safe and low-cost have high density. However, the shuttling of highly soluble triiodide ions severely limits device's Coulombic efficiency. Herein, we demonstrate first time a double-layered cathode configuration with conductive layer (CL) coupled an adsorptive (AL) ZIBs. This unique structure enables formation reduction adsorbed I3– at CL/AL interface, successfully suppressing ion...
Catalytically active iron-containing silicon nanostructures prepared from a polyferrocenylsilane diblock copolymer have been used to produce single-walled carbon nanotubes with diameters of 1 nm or less. Spatially selective growth on lithographically defined catalyst islands has successfully demonstrated over large surface area.
Organic–inorganic hybrid perovskite (PVSK) compounds are at the forefront of photovoltaic research, consistently surpassing silicon solar cells in power conversion efficiency. Possessing high refractive index, broad absorption spectrum, and superior quantum yields, PVSK thin films theoretically also ideal candidates for luminescent concentrators (LSCs). In practice, however, possibility self‐absorption a continuous film, coupled with inherent instability materials, have hindered their use...
Poly(methacrylic acid)-grafted carbon nanotube-based thin films are found to significantly improve the neuronal differentiation efficiency, and relatively mature cells have been derived directly from hESCs, owing their excellent protein sequestration ability nanofibrillar characteristics. This novel material platform creates new opportunities in tissue regeneration field.
The World Health Organization's Expanded Programme on Immunization has led to a dramatic rise in worldwide vaccination rates over the past 40 years, yet 19.4 million infants remain underimmunized each year. Many of these have received at least one vaccine dose but may unprotected because they did not receive subsequent booster doses due logistical challenges. This study aimed develop injectable controlled release microparticles with kinetics that mimic common dosing regimens consisting large...
Electrochemical conversion of carbon dioxide (CO2) gas to value-added chemicals such as multicarbon (C2+) alcohols is a promising and attractive decarbonization strategy. However, there are tremendous challenges in tuning the intrinsic activity selectivity catalysts produce C2+ alcohols. In this work, we prepared CeO2–Cu composite catalyst via combination metallurgy dealloying method. The interfacial sites amorphous heterostructure improve adsorption key reaction intermediates *CO promote...
We report a method of fabricating nanotextured Ag surfaces using template self-assembled inorganic-containing block copolymer, polystyrene-b-polyferrocenylsilane. The with periodically ordered nanoscale features created by the self-organized copolymer are capable producing enhanced Raman signals. Using benzenethiol as probe molecule, an enhancement factor up to 106 has been observed. More importantly, is very uniform; less than 10% signal variation obtained. Furthermore, since size and...
A monolayer of gold-containing surface micelles has been produced by spin-coating solution formed the self-assembly gold-modified polystyrene-b-poly(2-vinylpyridine) block copolymer in toluene. After oxygen plasma removed template, highly ordered and uniformly sized nanoparticles have generated. Unlike other published methods that require reduction treatments to form gold zero-valent state, these as-synthesized are metallic gold. These demonstrated be an excellent catalyst system for growing...
A new type of crosslinked polyarylamide based film with a fibrillar morphology that is photomechanically responsive has been created. Without any additive or need pre-alignment, these films can actuate under NIR stimulation. By constructing the photoresponsive on top piezoelectric poly(vinylidene difluoride) film, electrical energy be generated excitation. This first polymer system exhibits response without conventional photosensitive moieties. Detailed facts importance to specialist readers...

Ultraviolet light induced changes in polyimide liquid-crystal alignment films were investigated. Infrared, UV-visible, x-ray photoelectron spectroscopy, and electron-spin-resonance measure- ments indicated that bond breaking subsequent oxidation reactions occur (SE7210, OCG284, DuPont 2555 2540) during the broadband UV illumination air. Mechanical rubbing has no effect on optical magnetic properties but it causes removal of UV-exposed film. Capacitance–voltage measurements indicate there is...
