Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Medytacja nad Pustką. Konteksty buddyjskie w „Końcówce" i „Szczęśliwych dniach” Samuela Becketta
Thanks to Buddhist contexts, present in S. Beckett's two long plays (The Endgame and The Happy Days) we understand that death, signifying the ultimate Nothingness and Emptiness appears to be the change of the perceiving substance, which getting rid of ...

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Sprocket is one of the main components in two-wheeled vehicles that transfer the rotary force from the engine to the rear wheels of the motorcycle. Because of this main function, the sprocket wears out faster due to friction between the chain and the ...

Impact of symmetry breaking on the Flame Transfer Function of a laminar premixed flame [PDF]
This work presents a numerical study of the acoustic response of a laminar flame with tunable asymmetry. A V-shaped premixed flame is stabilised in the wake of a cylindrical flame holder that can be rotated.

Waveguide Photoactuators: Materials, Fabrication, and Applications
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Highly Flexible and Conformable ZnO/FeGa Magnetoelectric Heterostructures for Skin wound Healing
The magnetic field‐induced electric field generated by a highly flexile ZnO(piezoelectric)/FeGa(magnetostrictive) magnetoelectric heterostructure embedded in the low Young's modulus elastomer PDMS has been used to stimulate the wound healing processes.

Experimental Studies of Flame Transfer Function in Acoustically Excited Rijke Burners
本研究實驗探討一聲波激擾之垂直管道,位於管道下方一預混層流火焰之火焰移轉函數。本實驗類似於Rijke管的配置方式,在管道中一端分別導入三個不同聲納之燃燒爐。火焰轉移函數係由火焰區上下游所量測之聲波強度來決定,它與火焰上下游的壓力及速度有關。正值得火焰轉移函數代表火焰可能產生自發性振盪。研究結果顯示火焰轉移函數與火焰所在位置之流聲導納有著很大的關聯。火焰在聲波場所在之位置決定火焰轉移函數之正負值,同時,也決定其大小,火焰當量比所扮演的角色,僅是決定火焰轉移函數之大小 ...
