Ethology and Overwintering of \u3ci\u3ePodalonia Luctuosa\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
The nesting and overwintering behavior of Podalonia luctuosa (Smith) was studied in New York and Colorado. Females provisioned shallow (ca. 2 cm deep), unicellular nests with a single cutworm (Noctuidae) during April, May, and July.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

open access: yesAdvanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
