Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame

open access: yesAdvanced Functional Materials, EarlyView.
High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

open access: yesAdvanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Strengthing Of Rc Columns

open access: yes, 2016
The deterioration of concrete structures might be due to ageing, poor maintenance, corrosion due to poor environmental conditions and accidental situations like earthquakes. The need to upgrade the deteriorated civil engineering infrastructure greatly enhances with the ever increasing demands. Therefore rehabilitating and retrofitting civil engineering
