私は27歳で独立の研究室を始めるにあたり、伏見譲さんに
ユニオン技研を紹介され、製造を依頼しました。
これが私と長村さんとの出会いです。長村さんがユニソクとして独立してからは、蛋白質の変性・再生にも使用できる複雑なミキサーなど、種々のミキサーの開発に一緒に注力しました。
その後も長村さんとは、お亡くなりになる直前まで、いろいろ議論しました。
お亡くなりになって、長村さんの存在の大きさを今さら感じています。
さみしいです。
関西医科大学 名誉教授 木原裕様より心中よりお悔やみ申し上げます。
長村様には若いころから大変お世話になり共にナノ科学の発展のために励ましあってまいりまして研究室では長村様の開発された装置を何台かお納めいただき、長きにわたり愛用させていただきました。
ご退職されてからも、
なんどかお会いして若き日の活躍を称えあったことを想い起こします。
ご冥福を心からお祈りしております。

長村さんが亡くなられたとのこと、大変残念に思っています。長村さんには測定装置のことなどで大変お世話になり感謝しています。学生の頃から分光光度計やガス圧式のストップトフローなどのいくつかの装置を使わせていただきました。特にストップトフロー装置との関わりは現在のユニソク製の装置も含めて44年にもなりました。この間何度かお会いして装置のことをいろいろと教えていただいたことを昨日のことのように思い出しています。
愛知教育大学 元教授 稲毛正彦様より
長村氏には、
長い間、装置の作製でお世話になりました。
大抵は、研究室に来られて、作製する装置について話し合いながら仕事を進めて下さいました。
そうして完成した市販品でない装置は独自性と操作性に優れ、研究室の卒論生、大学院生は何の疑いも持たずに自由に使いこなして、数々の論文を作成することが出来ました。
今考えると、
このような多彩な装置を研究室に備えられたことは、幸運以外の何物でもないと思います。
長村氏の技術開発への思いとその手法が、ユニソクの方々によって継承され、発展されることを願って、長村様のご苦労とお力に思いをはせる次第です。

Sales Meeting 2023
Inviting nine people of seven distributors from the USA,
China, Germany, Taiwan and Korea this year,
UNISOKU finally held sales meeting for the first in four
years!
As this event was originally scheduled to be held
every two years, there was no end to the topics ofconversation with the distributors about recent
developments, such as business inquiries.
アメリカ、中国、
ドイツ、台湾、韓国から７社９名の代理店を招待し4年振りの開催が実現しました！
当初２年毎の開催予定に対して前回から久々の再会ということもあり、代理店の方々とは引合等の近況報告で話題が尽きませんでした。

Invaluable communication that cannot be achieved online
オンラインでは叶わない貴重な交流
This time, we were reminded of the importance of face-to-face meetings in which we could see facial expressions
and reactions of the participants. After the presentation from UNISOKU, there were many questions. We are happy to
see that our information is being conveyed more accurately to the distributors. We are sure that they will take what
they learned from this meeting and apply it to their customer service in their own countries.
今回、相手の表情や反応が見える形での対面のミーティングの重要性を再認識しました。ユニソクからの発表に対したくさんの質問が飛び交い、代理店には私たちの情報がより正確に伝わっていることの証としてうれしく思いました。
代理店は本会議で学んだことを自国でのカスタマーサービスに活かしてくれることと思います。
On the last day, we had an optional sightseeing day, which included a cruise around
Osaka City on an amphibious bus and a winery tour at Kawachi Winery, which wasfeatured in Newsletter 2021.
For even Osaka local people, it is rare to have a chance to ride on an amphibious
bus. The view of Osaka city from the amphibious bus was refreshing. Kawachi Winewas once served at the G20 Osaka Summit banquet. The winery has been cultivating
grapes since the mid-Meiji period and its taste of wine is characterized by its sweet
aroma and dry taste.
At the winery, about 10 kinds of wine and plum wine were served for tasting.
The wines were so good that participants bought them as souvenirs.
最終日にはオプションの観光日を設け、水陸両用バスで大阪市内をクルーズした後、ニュースレター2021でも紹介した河内ワインにてワイナリー見学と試飲を行いました。
大阪に住んでいてもなかなか乗る機会がない水陸両用バスからの大阪市内の景色は新鮮でした。河内ワイナリーはG20大阪サミット(2019)の晩餐会で振る舞われたこともあり、明治中期からブドウ栽培が盛んで香りが甘く辛口なところが特徴です。
ワイナリーでは10種類ほどのワインや梅酒を試飲でき、参加者がお土産に購入して帰る
ほど美味しいものでした。

Thermodynamic Control of Intramolecular Singlet Fission and Exciton Transport in Linear Tetracene Oligomers

Publication Introduction 論文紹介

S. Nakamura et al., Angew. Chem. Int. Ed. 62 e202217704 (2023).

Recently, singlet fission (SF), a multiexciton (a)generation process that can raise theefficiency of exciton generation up to 200 %,(b)
has been actively investigated as anext-generation photo-energy utilization.
To enhance the efficiency of SF,
Dr. Nakamura of Prof. Hasobe’s group, Keio University and co-researchers
proposed a molecular design strategy by linear oligomers, and they newly(c)synthesized a series of homo-tetracene [(Tc)n], and hetero-tetraceneoligomers [TcF3-(Tc)4-TcF3], then evaluated those performances byelectron paramagnetic resonance (EPR) and femtosecond to millisecond
transient absorption (TA) measurements. Especially, they made full useof CoolSpeK with picoTAS and TSP-2000, namely, they measured
temperature dependence of rate constants of each process by TA toprecisely calculate thermodynamic parameters and succeeded in
explaining the high efficiency of SF in both (Tc)n and TcF3-(Tc)4-TcF3.
(d)
Especially, efficient localization of exciton trapping was confirmed in
TcF3-(Tc)4-TcF3, with a trapped triplet yield of 176% due to the increaseof entropy change, ΔS.
Such thermodynamic control of SF by this molecular design will provide
a new perspective for novel photofunctional systems such as quantum
information science and solar energy conversion.

This study focuses on magic-angle twisted trilayer graphene (MATTG), exploring its correlated electronic phases thatbreak underlying symmetries. Using scanning tunneling microscopy, Kim, Choi et al. (Nadj-Perge group, California
Institute of Technology) identify interaction-driven spatial symmetry breaking in low-strain samples, revealing atomic-scale reconstruction and correlated gaps in the tunneling spectrum. The observed Kekulé supercell suggests
spontaneous inter-valley coherence between electrons, persisting across magnetic fields and temperatures associated with gap development. Large-scale maps show the coexistence of atomic-scale reconstruction and translation
symmetry breaking at the longer moiré scale. The auto-correlation and Fourier analyses support the theoretically
proposed incommensurate Kekulé spiral order. The findings provide insights into MATTG correlated phases, suggesting that superconductivity arises from an inter-valley coherent parent state.

Evidence for Chiral Superconductivity on a Silicon Surface
Ming, Wu et al., Nat. Phys. 19, 500 (2023).

Product used: USM1300

Low-dimensional superconductivity has attracted considerable interest for decades. Tin (Sn) adatoms on a silicon (Si)substrate at a one-third monolayer coverage form a two-dimensional triangular lattice with unpaired electrons. The
electrons organize into an antiferromagnetic Mott-insulating state, but doping the Sn layer with holes transforms it intoa two-dimensional conductor that exhibits superconductivity at low temperatures. The repulsive interactions andfrustration due to the triangular lattice suggest the possibility of unconventional superconductivity. Using scanningtunneling techniques, Ming et al. (Wang group,

17This study addresses the longstanding pursuit of electric spin control in solid-state physics, aiming to enhance information processing efficiency. The approach involves transitioning spintronics to the atomic scale. Using electron spinresonance scanning tunneling microscopy (ESR-STM), Kot et al. (Ast group, Max-Planck-Institut für Festkörperforschung) demonstrate electric control of spin resonance transitions in individual TiH molecules. Significant bias
voltage-dependent shifts in the ESR signal, approximately ten times its line width, are observed. These shifts are
attributed to the electric field in the tunnel junction, causing a displacement of the spin system and altering the g-factor
and effective magnetic field of the tip. The study further demonstrates direct electric control of spin transitions incoupled TiH dimers, presenting new possibilities for coherent control of interconnected spin systems and contributing

This study investigates Majorana bound states, which are collective excitations in solids with properties of Majorana
fermions, known for being their own antiparticles. In iron-based superconductors, zero-energy states in vortices havebeen suggested as potential Majorana bound states, but the evidence has remained debated. Using scanning tunneling noise spectroscopy, Ge et al. (Milan Allan group, Leiden University) examined tunneling into vortex bound statesin the superconductors NbSe2 and FeTe0.55Se0.45. They observed charge transfer of a single electron in both cases.
For FeTe0.55Se0.45, the findings exclude Yu–Shiba–Rusinov states, supporting the possibility of both Majorana andtrivial vortex bound states. The results provide insights into exotic states in vortex cores and implications for future
Majorana devices, but further theoretical investigations are needed, especially regarding charge dynamics andsuperconducting tips.

This study investigates moiré superlattices formed by transition metal dichalcogenides, specifically focusing on twisted
double-bilayer WSe2. Using a scanning single electron transistor (SET), Foutty et al. (Feldman group, Stanford Univ.)
conducted local electronic compressibility measurements to explore electronic correlations within the moiré bands
associated with the Γ-valley. The study identifies charge-ordered phases at various integer and fractional moiré
fillings. The magnetic field dependence of energy gaps and chemical potential measurements upon doping reveal
spin-polarized ground states with spin-polaron quasiparticle excitations. Additionally, applying a displacement field

This study investigates layered crystalline materials with transition metal atoms arranged on a kagome network,
focusing on the kagome metal CsTi3Bi5, which is isostructural to the vanadium-based kagome superconductor
AV3Sb5. It is known that, unlike AV3Sb5, CsTi3Bi5 does not exhibit a detectable charge density wave state. Li et al.
(Zeljkovic group, Boston College) performed spectroscopic-imaging scanning tunneling microscopy measurements
and density functional theory calculations to reveal significant electronic correlation effects at low energies. They
discover an electronic anisotropy breaking the sixfold symmetry of the lattice, originating from both in-plane andout-of-plane titanium-derived dorbitals. The findings suggest a

highlighting the role of electronic
orbitals in CsTi3Bi5.

About JapaneseConvenience Stores
日本でコンビニエンスストア（コンビニ）が生まれたのは1969年のことです。
（諸説あり） 1975年から24時間営業が始まり、店舗数は日本全国で57,000軒を超えるほど増加し、いまや不動産情報を見れば「徒歩5分圏内コンビニ」という紹介が当たり前のように書かれるほどになりました。

new products are introduced every week, and you may be able to find something that reflects the seasonal occasions.
For example, in January many strawberry sweets were on display.

Convenience stores(Kombini)
were first established in Japan in 1969.
(There are various views.)
Since 1975, they started 24-hour
operation. Nowadays, the number ofstores has increased to more than 57,000
across Japan and it is now common
description to see"Convenience stores within 5 minutes
walking distance"in real estate information.

べ物を温めることもできますし、店舗によってはイートインコーナーが設けられていることもあります。
夜中に急にスナック菓子が食べたくなった時も、早朝にエスプレッソマシンで入れたコーヒーを飲みたくなった時も、思い立ったらすぐに手に入ります。

You can also heat up the food you buy in the microwave oven installed in the store, and some stores have eat-in corners.
When you have a sudden craving for snacks in the middle of the night or a cup of coffee made by an espresso machinein the early morning, that will come true.

都市部では少し歩けばコンビニ、逆方向に歩いてもコンビニ、場所によってはコンビニの隣にコンビニがあり、どこでも見かける、生活に密着した商業施設となりました。

The floor area of the stores is very compact, and the products are arranged in typically thesame layout in any stores. The selection is very extensive, offering lunchboxes, bread, sweets,
beverages, alcohol, office supplies, and household goods. Especially for foods and beverages,

宿泊するホテル内や、ホテルのすぐ近くにコンビニがあることも多いです。
日本に来られた時はぜひ利用してみてください。

There are often convenience stores in the hotels or nearby the hotels. Please try
Japanese convenience stores when you come to Japan.
