Battery electrode aging processes, biofilm growth, crystallization, and transport/signaling across cellular membranes are only a few examples of such phenomena. This special issue delves into applied electrochemistry and nonlinear optical techniques applicable to surface characterization.</p>\u0000<p>Near-field techniques usually require specialized instrumentation. However, although much improvement has been made over recent years, many surface-characterization tools are still limited to samples in a vacuum; therefore, in-situ and in-operando experiments are impractical. On the other hand, optical techniques are more flexible and less demanding regarding sample handling. Still, they usually need more surface specificity and sensitivity, and in principle, they have a lower resolution compared to electron beam-based techniques.</p>\u0000<p>On the other hand, optical techniques also offer different contrast modalities. For example, Second-harmonic generation (SHG) or surface-enhanced Raman spectroscopy (SERS) are versatile optical tools for probing surfaces. From symmetry considerations, SHG responses are forbidden from the bulk of metallic electrodes and observed only from the surface where the symmetry is broken. Thus, high sensitivity can be attained using SHG, and when both SHG and SERS are combined, selectivity and sensitivity can be achieved. In addition, nanofabrication of metallic surfaces can further improve the sensitivity of SHG and SERS by orders of magnitude due to local field enhancement.</p>\u0000<p>In recent years, much improvement has been made in super-resolution microscopy and imaging, enabling fast yet high-resolution imaging over areas as large as half-by-half-millimeter squares. For the field of electrochemistry, such development is very important since it may open the door for real-time optical characterization of solid-liquid interfaces during charging/discharging cycles, which can potentially lead to significant improvements in the performance and durability of the electrode. These contributions not only expand the horizons of applied electrochemical science but also underline its influence on our daily lives and its pivotal role in addressing global challenges related to climate and energy.</p>","PeriodicalId":14686,"journal":{"name":"Israel Journal of Chemistry","volume":"175 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139465262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lerner (August 28, 1938–December 2, 2021), whose visionary presidential leadership and guidance for over a quarter century (1987–2012) catapulted The Scripps Research Institute (La Jolla, California and Jupiter, Florida) into a powerhouse at the interface of chemistry, biology, and medicine. Following is a colorful assortment of twenty contributions that collectively paint a picture of a man who intuitively and ingeniously blended organic chemistry and immunology to arrive at new molecular compositions and concepts that have defined contemporary small and large-molecule drug discovery.&lt;/p&gt;&lt;p&gt;Prof. Lerner's mix of creativity, fearlessness, and unboundedness conceived and conceptualized inventions like catalytic antibodies, antibody libraries, and DNA-encoded small molecule libraries. Several articles in this Special Issue pay tribute to these transformative discoveries, depicted in the cover image. Other articles add additional facets to the theme of bioinspired chemistry. Sprinkled in are numerous anecdotes of Prof. Lerner's rebellious and humorous nature that made him, as his friend and presidential successor at Scripps Research, Prof. Peter G. Schultz, notes, “one of a kind […] who defied boundaries and lived life to its fullest.”&lt;/p&gt;&lt;p&gt;Above all, Prof. Lerner was an enabler of ideas who recruited, protected and connected brilliant minds at every academic level at The Scripps Research Institute (now Scripps Research). He cherished their discoveries at least as much as his own, corroborated by one of his mentees, Prof. Benjamin F. Cravatt, who writes in his contribution, “I have never met someone so accomplished who took their greatest joy in the accomplishments of others.” Prof. Lerner's infectious energy and enthusiasm catalyzed the careers of graduate students, postdocs, and faculty on both the Pacific and Atlantic campuses of Scripps Research, as well as beyond the United States, as reflected here by contributions from Israel, Korea, Russia, Sweden, Switzerland, and the United Kingdom. Many of us have come together for this Special Issue as a tribute to the unconventional explorer, builder, and leader who transformed and empowered our thinking and doing. We are fortunate to have crossed paths with him.&lt;/p&gt;&lt;p&gt;Since the Israel Journal of Chemistry is the official Journal of the Israel Chemical Society (ICS), we welcome the recently established ICS-Lerner Prize and Lectureship that commemorates the legacy of Prof. Richard A.
