In this study, a new class of nanostructures with nanoscale constrictions is introduced as a prospective approach to increase the thermoelectric conversion efficiency of materials. To demonstrate this idea, a laterally arranged nanowire-based structure called a Nanowire Chain (NWC) with one-dimensional nano-constrictions is studied within this work. A combination of classical molecular dynamics and ab-initio calculations is used to evaluate the lattice thermal conductivity and the electronic properties of the structures. A notable order of magnitude reduction of thermal conductivity with respect to the precursor non-sintered nanowires was observed and is attributed to the variation in phonon vibrational density of states along the heat transfer direction caused by the shape of the structure. This was found to be a unique quantum-confinement based effect present in NWC structures. Through first principles calculations, it is revealed that a maximum thermoelectric figure of merit ((ZT)) of 1.9 was obtained for Si NWCs at a carrier concentration of 3.8 × 1020 cm−3 at room temperature. Increasing the temperature to 600 K, the maximum (ZT) increases to 5.4 at a carrier concentration of 2.6 × 1020 cm−3. This two-order improvement in thermoelectric (ZT) over doped bulk Si is achieved using the NWC structures. Consequently, the present study demonstrates that engineering crystalline nano-constrictions could be a promising technique for developing high (ZT) thermoelectric materials.</div>","PeriodicalId":776,"journal":{"name":"Silicon","volume":"17 7","pages":"1717 - 1727"},"PeriodicalIF":2.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In histochemical study, Cd-treated leaves showed intensified blue colour with NBT indicating ROS localization. Genotoxicity study by RAPD confirmed that SiO2NPs could mitigate genotoxic stress with minor impact at genomic DNA level, reflecting higher genomic template stability. Additionally, polymorphism was less pronounced in Cd + NP treated sets than in Cd treated counterpart. Sole Cd content of SiO2NPs treated plants also decreased. Nonetheless, SiO2NPs hydroponics followed by foliar was the most accepted application route in enhancement of antioxidant defence and reduction of stress markers, Cd contents in rice.

Coll acted as an organic material, associated with its prevalence and importance in the human extracellular matrix, while silica contributed as an inorganic bioactive material. However, the inherent stiffness of these materials was mitigated by the addition of TEC, known for its biodegradability and non-toxic properties, improving the mechanical attributes of the hybrid. FTIR spectra and TGA thermal analysis confirmed the presence of Coll in the synthesized hybrids. Additionally, the thermal analysis revealed that the incorporation of varying concentrations of Coll influenced the material's thermal stability. SEM analysis revealed that the structure of the silica hybrid containing 8% Coll exhibits features characteristic of a fiber-reinforced composite, along with traces of porosity of varying sizes.

MWIR filters hold significant importance due to their extensive applications in thermal imaging, spectroscopy, and sensing. The primary aim of this study is to achieve the maximum figure of merit (FOM) through precise tuning of the grating's structural parameters. Initially, the transmission spectra of the filters in the 9–11 µm wavelength range were simulated for various structures using the finite element method (FEM). Analysis of these spectra revealed two resonance modes exhibiting different interference behaviors based on changes in asymmetry parameters. Key parameters of each resonance mode, including transmission, peak wavelength, linewidth, and dip depth, were evaluated to calculate quality factors (Q-factor) and FOM. To optimize the FOM, two approaches were employed: artificial neural network (ANN) fitting on FEM data and direct optimization using the genetic algorithm (GA). The ANN model predicted a maximum FOM of 11.51 1/µm with optimal parameters: wsx = 80%, wsy = 10%, tsy = 10%, and tsx = 80%. Subsequently, the GA achieved an optimal FOM of 13.55 1/µm through direct parameter space search, with the best parameters being tsx = 86.98%, wsx = 65.39%, tsy = 45.76%, and wsy = 31.45%.
