“…S20B). We believe that the gap between theoretical and experimental DT max values can be further narrowed by optimizing the interfacial contacting structure and the size of thermoelectric particles in the device (49,50). Therefore, much higher performance in both thermoelectric power generation and Peltier cooling are expected through future optimizing of the contact resistance and shape factor, which are believed to be the critical factors that determine the performance of thermoelectric devices.…”

Thermoelectric technology has been widely used for key areas, including waste-heat recovery and solid-state cooling. We discovered tin selenide (SnSe) crystals with potential power generation and Peltier cooling performance. The extensive off-stoichiometric defects have a larger impact on the transport properties of SnSe, which motivated us to develop a lattice plainification strategy for defects engineering. We demonstrated that Cu can fill Sn vacancies to weaken defects scattering and boost carrier mobility, facilitating a power factor exceeding ~100 microwatts per centimeter per square kelvin and a dimensionless figure of merit ( ZT ) of ~1.5 at 300 kelvin, with an average ZT of ~2.2 at 300 to 773 kelvin. We further realized a single-leg efficiency of ~12.2% under a temperature difference (Δ T ) of ~300 kelvin and a seven-pair Peltier cooling Δ T max of ~61.2 kelvin at ambient temperature. Our observations are important for practical applications of SnSe crystals in power generation as well as electronic cooling.

“…Alternatively, the selection of biocompatible biopolymers for coating mammalian cells has also been explored as a suitable option. [50,60,64] Among the different methodologies that have been employed to modify the cell surface, the alternate adsorption of oppositely charged polyelectrolytes, the so-called layer-by-layer (LbL) technique, has been the most widely used. [65] This methodology leads to the formation of a thin polyelectrolyte multilayer (PEM) film around the cell surface, forming a physical barrier.…”

Breakthroughs in precision cell surface engineering tools are supporting the rapid development of programmable living assemblies with valuable features for tackling complex biological problems. Herein, the authors overview the most recent technological advances in chemically‐ and biologically‐driven toolboxes for engineering mammalian cell surfaces and triggering their assembly into living architectures. A particular focus is given to surface engineering technologies for enabling biomimetic cell–cell social interactions and multicellular cell‐sorting events. Further advancements in cell surface modification technologies may expand the currently available bioengineering toolset and unlock a new generation of personalized cell therapeutics with clinically relevant biofunctionalities. The combination of state‐of‐the‐art cell surface modifications with advanced biofabrication technologies is envisioned to contribute toward generating living materials with increasing tissue/organ‐mimetic bioactivities and therapeutic potential.

Impact of macro molecular theory on the progress of sensing sciences and technology has been presented in the light of materials developments, advances in physical and chemical properties. The chronological advances in the properties of macromolecules have significantly improved the sensing performances towards gases, heavy metals, biomolecules, hydrocarbon, and energetic compounds in terms of unexplored sensing parameters, durability, and working lifetime. In this review article, efforts have been made to correlate the advances in structure and interactivity of macro-molecules with their sensing behavior and working performances. The significant findings on the macromolecules towards advancing the sensing sciences are highlighted with the suitable illustration and schemes to establish it as a potential “microanalytical technique” along with existing challenges.
