Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Targeting PLD3 Reverses the Immunosuppressive Niche by Reprogramming Tumor‐Associated Macrophages and Potentiates Antitumor Immunity

Advanced Science, EarlyView.
PLD3 activates the lysosomal‐AKT‐NF‐κB axis to drive cellular senescence in macrophages, establishing an immunosuppressive TME by limiting the infiltration of cytotoxic T, NK, and NKT cells, which confers resistance to anti‐PD‐1 therapy. Abrine inhibits PLD3 expression, restoring antitumor immunity and synergizing with anti‐PD‐1 treatment.

Chemical pulping: the influence of the molecular weight of added xylan on pulp properties [PDF]

, 2013
The aim of this study was to investigate if added beech xylan with low molecule weight (Mw) could penetrate into the fiber wall to a greater extent compared to xylan with high Mw. The high Mw (ca 11000) xylan was degraded using enzymes to obtain xylan with low Mw (ca 1800).

Synthesis of Cyclopropene‐Modified Fatty Acids Allows Single‐Cell Quantification of Uptake by Immune Cells

Angewandte Chemie, EarlyView.
Cyclopropene fatty acids have been made that allow the study of fatty acid uptake in complex mixtures of immune cells with single cell resolution and combined with metabolic and proteomic analysis so that for the first time nutrient uptake can be correlated to the phenotype of single immune cell.

Influence of Cooking Conditions on Pulp Properties of Acacia auriculiformis in Kraft Pulping

JAPAN TAPPI JOURNAL, 2007
Acasia auriculiformisを，蒸解時間，温度および活性アルカリ添加率などの操業因子を変えたクラフト蒸解に供した。セントラルコンポジト法を適応して，パルプ特性（全収率，精選収率，カッパー価，裂断長，比破裂強度，比引裂き強度）に及ぼす操業条件の影響を調べた。三つの独立変数からなる二次多項式モデルは，Acasia auriculiformisのKP蒸解を正確に表現できることがわかった。最小R2値は0．94以上であり，提案した式に良く合致することを示している。操業変数の中央点における精選収率，全収率，カッパー価，裂断長，比破裂強度，比引裂き強度の値は，それぞれ43．5％，44．6％，26．1，41．7N. m／g，3．3kPa. m2／g，12．3mNm2／gであり，ほぼ予測値に近い。

IMPACT OF ACID WASHING AND CHELATION ON Mg(OH)2-BASED HYDROGEN PEROXIDE BLEACHING OF MIXED HARDWOODS CMP AT A HIGH CONSISTENCY

BioResources, 2010
The removal of transition metal ions is crucial for improving the efficiency of subsequent peroxide bleaching. Acid-washing and chelation have been proposed for such a purpose. However, their influences on the Mg(OH)2-based peroxide bleaching of hardwood
