Microstructure and thermal conductivity of high thermal conductivity carbon/ carbon composites

Cailiao gongcheng, 2020
Porous carbon/carbon (C/C) composites prepared by pitch-based carbon fiber and mesophase pitch were densified by chemical vapor infiltration (CVI) and precursor impregnation process (PIP).

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Influence of aluminum alloy interlayers with different composition on bonding strength of high volume fraction aluminum matrix composites

Fenmo yejin jishu
Using the aluminum alloys as the interlayers, the 60%SiC/6061Al composites (volume fraction) were bonded by hot isostatic pressure, the influence of aluminum alloy interlayers with varying composition (without Al, 1060Al, and 4047Al) on the ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Superior ablation resistance of plasma sprayed SiC based coating by structural optimized powders

Journal of Materials Research and Technology
Pristine SiC coating prepared by plasma spraying is difficult to achieve good ablation resistance at high temperature due to its weak SiO2 scale. Besides incorporation by ultra-high temperature ceramics, the modification of the SiC coating from its ...

Synthesis of PAN with adjustable molecular weight and low polydispersity index (PDI) value via reverse atom transfer radical polymerization

Designed Monomers and Polymers, 2019
The reverse atom transfer radical polymerization (RATRP) of acrylonitrile (AN) was carried out in N, N-dimethylformamide (DMF) with AIBN as initiator, FeCl3•6H2O/triphenylphosphine (PPh3) and FeCl3•6H2O/pentamethyldle-thylenetrlamlne (PMDETA) as ...

Introduction to composite materials

, 1980
The combination of materials to form a new material system with enhanced material properties is a well documented historical fact. For example, the ancient Jewish workers during their tenure under the Pharaohs used chopped straws in bricks as a means of ...

Finite element simulation of delamination growth in composite materials using LS-DYNA [PDF]

, 2009
In this paper, a modified adaptive cohesive element is presented. The new elements are developed and implemented in LS-DYNA, as a user defined material subroutine (UMAT), to stabilize the finite element simulations of delamination propagation in ...
