Electrochemical carbon dioxide reduction (CO2RR), as an emerging technology, can combine with sustainable energies to convert CO2 into high value‐added products, providing an effective pathway to realize carbon neutrality. However, the high activation energy of CO2, low mass transfer, and competitive hydrogen evolution reaction (HER) leads to the unsatisfied catalytic activity. Recently, Indium (In)‐based...
For the last two decades, research has addressed whether the glass transition temperature and the molecular motions on the surface of organic films are significantly different from those inside the bulk glasses. It is reported that the surface of the photochromic diarylethene film prepared by vacuum deposition has fluidity and the vacuum deposition of small amount of rubrene molecules induces surface...
Although various types of bifacial solar cells exist, few studies have been conducted on bifacial semitransparent CuInSe2 solar cells (BS‐CISe SCs) despite the attractive potential in power generation from both sides in an albedo environment.

Designing a microenvironment that drives autonomous stromal cell differentiation toward osteogenesis while recapitulating the complexity of bone tissue remains challenging. In the current study, bone‐like microtissues are created using electrohydrodynamic atomization to form two distinct liquefied microcapsules (mCAPs): i) hydroxypyridinone (HOPO)‐modified gelatin (GH mCAPs, 7.5% w/v), and ii) HOPO‐modified...
Mechanically sensitive tissues (e.g., skeletal muscles) greatly need mechanical stimuli during the development and maturation. The extracellular matrix (ECM) mediates these signals through nonlinear viscoelasticity of collagen networks that are predominant components of the ECM. However, the interactions between cells and ECM form a feedback loop, and it has not yet been possible to determine the...
Manganese is an attractive element for sustainable solutions. It is largely available in the earth's crust, making it ideal for cost‐effective and large‐scale applications.
