Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Removal of boron from wastewater of geothermal power plant by selective ion-exchange resins. I. Batch sorption-elution studies

open access: yes, 1999
Boron removal was studied using N-glucamine-type resins Diaion CRB 02 and Purolite S 108. The resin Diaion CRB 02 exhibited a higher sorption capacity for boron removal from 0.01 M H3BO3 solution than did Purolite S 108.
