Young engineers often ask about whether to select membrane or thin shell or thick shell for modelling area elements such as RCC slab. I am going to talk about the difference in the results when choosing thin-shell or membrane. This is what makers of ETABS says about the topic. I will quo...
All eggs produced at all time points (week 1 to 10) between both treatment groups were graded as USDA Grade AA of superior quality, with thick, firm egg whites and defect-free egg yolks. Additionally, the shells were clean and without defects. There were minimal number of blood spots or ...

attacked another sensing aspect – selectivity; they fabricated a ZnO-based H2 sensor modified by a thin SIM-1 hydrogen selective membrane, revealing very high selectivity towards H2 at high temperatures [98]. Lupan et al. electrochemically synthesized, in a single-step process, an ultra-low ...
We note that our excellent results of 50-μm-thin membrane PEMWEs might not be directly applicable to practical applications, as high crossover of hydrogen might occur under pressurized operations [47]. Elsewhere, strategies to mitigate hydrogen crossover have been developed, such as integration ...
Ockleston [10] showed that the capacity of a flat slab can be five times higher than that predicted by an upper-bound yield line analysis due to an arching effect he named compressive membrane action, which occurs when lateral movement is restrained. This supports the notion that an ...
(Supplementary Fig.9and Fig.4a). The larval shell is not uniform over the transversal section and it appears to be brighter at the outside part. Note that the darkest contrast indicates that a part of the mineral was removed during the ultrathin-section preparation. Interestingly, a cren...
The phenomena can be ascribed to the presence of C or an oxide shell outside of the silicon, which can offer a static surface for the formation of a thin and stable SEI, preserving the anode from irreversible reactions with the electrolyte29–31,44. In addition, in the work of Li's ...
Core–shell structured catalysts, made by placing either a monolayer or a thin layer of a noble metal on relatively cheap core-metal nanoparticles, are fascinating and promising fuel cell catalysts due to their high utilization of noble metals. Here, we report our development of a core–shell ...
We used the liquid flow TEM holder Poseidon 500 (Protochips, North Carolina, USA). A pair of chips were used. Two thin silicon nitride (SiN) membranes of the liquid cell window (50 nm thick for each membrane, 550 × 20 μm for window) encapsulatesthe gap of 50 nm, allowi...
