ESTUDO DA BRANQUEABILIDADE DA POLPA KRAFT DE EUCALIPTO

Ciência Florestal, 2015
The aim of this study was to evaluate how the pulp bleachability ability is correlated with the wood chemical characteristics, the cooking conditions, the kappa number of the brown pulp and the bleaching sequences, based on the pulp bleached brightness ...

Neuromorphic Electronics for Intelligence Everywhere: Emerging Devices, Flexible Platforms, and Scalable System Architectures

Advanced Materials, EarlyView.
The perspective presents an integrated view of neuromorphic technologies, from device physics to real‐time applicability, while highlighting the necessity of full‐stack co‐optimization. By outlining practical hardware‐level strategies to exploit device behavior and mitigate non‐idealities, it shows pathways for building efficient, scalable, and ...

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

Advanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Highly Entangled Bottlebrush Polymer Networks

Advanced Materials, EarlyView.
Bottlebrush polymers are difficult to entangle, enabling ultrasoft yet brittle networks. We report highly entangled bottlebrush elastomers that remain ultrasoft (∼1 kPa) yet stretch to ∼1800% and exhibit exceptional fatigue resistance. Their intrinsic fatigue strength—fatigue threshold normalized by modulus—surpasses that of highly entangled linear ...

THE EFFECTS OF COOKING PARAMETERS ON THE YIELD AND KAPPA NUMBER

Triticale (Triticosecale, Wittm. ex A. Camus) saplarından oksit ilaveli NaOH-O2 yöntemiyle optimum kağıt hamuru verim ve Kappa numarasını belirlemek için 27 adet pişirme denemesi yapılmıştır. Yapılan pişirme denemeleri sonucunda ekonomiklik de göz önüne alındığında pişirme sıcaklığı1200C, pişirme süresi 20 dakika, Al2O3 oranı %1, NaOH oranı %16 ...

One Number, Two Names: kappa = tau = 0.9539

A short genesis note on a single empirically-anchored number, 0.9539, which appears in the author's prior work under two distinct labels: tau, the cosine-similarity rejection threshold in the Anti-Drift Cognitive Control Loop (ADCCL); and kappa, the Sovereign Invariant of Geometrically Ordered Dynamics (GOD Theory), which couples redshift-dependent ...
