True Random Number Generator for Robust Data Security via Intrinsic Stochasticity in a 2D hBN Threshold Switching Memristor

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate true random number generator (TRNG) circuits based on a 2D hBN threshold switching memristor integrated with passive components. Leveraging its intrinsic stochastic behavior, the spike generator produces output fluctuations directly converted into random bits via a comparator.

Determination of total titanium in titanium metal and titanium tetrachloride

open access: yesBUNSEKI KAGAKU, 1961
金属チタンおよび四塩化チタン中の全チタンの定量法につき,簡易化と迅速化の見地から容量法を詳細に研究し,つぎの諸方法を確立した.金属チタンは試料をフッ化水素酸と硫酸にとかし,ホウ酸を加えて液状亜鉛アマルガムで還元する.のち四塩化炭素を加えて液状亜鉛アマルガムを分離し,還元液を硫酸第二鉄アンモニウム溶液で滴定し全チタンを求める四塩化チタンは試料を注射針付き注射器で塩酸に注入溶解させる.のち試料がバナジウムを含まない場合は金属チタンと同様に還元,滴定する.またバナジウム含有の場合は塩酸溶液に硫酸と過酸化水素水を加え硫酸白煙ののち液状亜鉛アマルガム還元,過マンガン酸カリウム滴定を行ない別に求めたバナジウム含量により補正を行なう.分析精度を変異係数(σ%)で示せば金属チタンで約0.1%,四塩化チタンで約0 ...

Self‐Refreshing Bi‐Based Active Sites for Efficient and Durable Electrochemical CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A self‐refreshing Bi‐based catalyst is developed through the fabrication of a novel basic bismuth nitrate pre‐catalyst, which exhibits differential active sites of Bi2O2CO3 at low potentials and metallic Bi phases at high potentials, self‐repairing capability, and thus wide‐potential‐window efficiency and ultralong durability toward electrochemical CO2

Chiral SURMOFs for Vibrational Circular Dichroism: Multiscale Modeling and Experimental Insights

open access: yesAdvanced Functional Materials, EarlyView.
The use of solid‐state vibrational circular dichroism (VCD) for MOFs is still somewhat unexplored, and in this work, it is shown that chiral surface‐anchored MOFs (SURMOFs) grown on CaF2 provide an excellent platform for VCD. Experimental results are validated through multiscale modeling, showing strong agreement across multiple spectroscopic ...

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...
