Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Fatigue Strength in Additive Toolmaking: A Study of Metal Binder Jetting and Electron Beam Melting for Processing Carbide‐Rich Cold‐Work Tool Steels

steel research international, EarlyView.
Focusing on the critical tap hole region of the blast furnace, this work examines binder characteristics, prepares tap hole clay with different formulations, and evaluates their physical properties. The findings confirm the advantages of composite binders and offer a new binder option for tap hole clay.

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

On the Maxumum Loop Gain of Chopper Amplifiers with a Make-before-break chopper

On the Maxumum Loop Gain of Chopper Amplifiers with a Make-before-break chopper
論文(Article) 著者の一人（中津山）によって発表されたチョッパ増幅器の精密な解析法を用いて，中央短絡形チョッパを用いたチョッパ増幅器の負帰還量の限（(安定をそこなわずに帰還できる最大ループ利得）を計算し実測値と比較検討した。その結果両者は良く一致し，今までほっきりしなかった時定数が小さい場合の帰還量の限界が計算で求められ，この形のチョッパを用いた増幅器の安定性が明らかになった。これは，増幅器を設計する時の一つの基準になるであろう。　　また，回路の時定数がチョッパ断続周期より大きい場合，誤差が少なく簡単に負帰還量の限界を求めることができる近似式が得られたので，これについても報告した。

Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

VIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...
